Dear PCE WG

I support progressing this draft to publication.

This draft provides immense value to the operator community for deployment
of RSVP-TE or segment routing with this new PCEP extension for a generic
optional color TLV to carry color attribute part of tuple for SR policy by
stateful PCE for color signaling  overlay VPN color to underlay SR policy
color, color to intent mapping binding candidate path (CP) ERO BSID to the
forwarding plane.

Kind Regards

[Pce] Re: WG Adoption of draft-li-pce-controlled-id-space-16

2024-06-03 Thread Gyan Mishra
Dear WG

Sorry for the late reply.

I support WG adoption of this draft and am willing to work on the draft.

Few comments after reviewing the draft.

For SR-MPLS there are two label rangers SRLB and SRGB.  So you may want to
have a label control space TLV with different IANA registry for sub TLV for
SRLB and SRGB.

Similarly for SRV6 Func ID control space TLV maybe have a separate IANA sub
TLV for LIB (Local ID block) and GIB (Global ID block).

IANA registry is not mentioned for BSID label or ID control space TLV.

Also this ID space concept should be applicable to RSVP-TE as well.

Also today a stateful PCE manages the LSP or SRv6 path PCE ERO via PCE
delegation, however does not allocate a new label or sid range to be
distributed to all nodes.  However now this draft manages the service sid
range.  In a SR PCE environment where this new ID capability is advertised,
is there any impact in  distribution of this new ID space to all nodes in
rebuilding the SR forwarding plane state.  This should be added to the
considerations section.

Kind Regards

Gyan

I support WG adoption of this work.  This work has had a long history and

Re: [Pce] WG Adoption of draft-peng-pce-entropy-label-position-10

2024-02-05 Thread Gyan Mishra
Hi Quan

RFC 8662 talks about many interesting and creative  ways to reduce the size
of the label stack.

Section 4  talks about ERLD and then 7.2.1 talks about ERLD value
computation.

I think it maybe good to mention what is discussed in both section 4 and
7.2.1.

Your draft does not use ERLD and uses ELP so I think explaining why ERLD
computation is not necessary specifically when using ELP flag.

I reviewed the draft and support WG adoption.

I believe this ELP PCE  capability extension maybe helpful in determining
the position to place the ELI. EL label.  According to RFC 8662 a {ELI,EL}
label must be placed after every SID in the sid list based on the ERLD.  I
maybe a good idea to explain why computing the ERLD would add complexity in
the ELI/EL insertion process and why a new mechanism using the ELP is
necessary.  Also why the ERLD computation is not required as described in
RFC 8662.

Re: [Pce] WGLC for draft-ietf-pce-segment-routing-policy-cp-12

2024-01-11 Thread Gyan Mishra
I support publication.

I have reviewed v12 and have a few minor comments.

At the end of the abstract section you could say forwarding planes of SR
instead of dataplane.  As the data planes of SR would be MPLS and IPv6.

Old
The mechanism is applicable to all data planes of SR (MPLS, SRv6, etc.).

New

The mechanism is applicable to SR forwarding planes of SR (SR-MPLS SRv6,
etc.).

My understanding is that as RFC 8664 is the base PCEP extension for SR and
this draft is an add on to the base SR PCEP extension to provide the CP
support.

My thoughts was a more appropriate name for the draft as "PCEP extension
for SR Policy Candidate paths" or "PCEP SR Extension for Candidate paths"

2023-02-17 Thread Gyan Mishra
I have read the draft and support publication of the PCE SRv6 extension.

I don’t see anything SRv6 compression related which uses the same endpoint
behavior semantics from RFC 8986 SRv6 PGM but with new endpoint flavors for
C-SID Next SID (Cisco uSID) and Replace SID (Huawei GSID).

Also the related caveat that with SRv6 uSID as compare GSID the SRH is not
present for less than 5 uSID hops loose or strict steering which can be
accomplished with underlay ISIS SR Algo advertisement as L2 EVPN and L3 VPN
service label is encoded into the FUNC field so so does not require PCE or
SR policy to instantiate.  With SRv6 uSID  stateful PCE and SR policy would
come into play for greater than 5 uSID uN shift-forward hops of steering.

I support WG adoption by the PCE WG.

SR Policy VPN service route color to intent mapping is an important aspect
of Segment Routing to instantiate per flow or per destination steering and
this draft provides a PCEP extension to carry the coloring inter domain.

This is a very useful and important draft for operators migrating to
segment routing.

Thank you

This draft is very useful for operators deploying SRv6 and I support
adoption.

Should the Yang model include all SRv6 endpoint behaviors defined in RFC
8986 SRv6 programming?

Also should the draft include RFC 9252 SRv6 BGP overlay service and
transposition scheme details as well as SRv6 load balancing?

As well should the draft include SRv6 compression Next uSID and Replace
G-SID endpoint behaviors?

2022-07-01 Thread Gyan Mishra
Dear WG

I support adoption by PCE WG and would be willing to work on the draft.

I support IFIT PCE extension to carry the IFIT attributes for in-situ IOAM
on path telemetry.  I do agree this would be very useful for operators.

I was looking for a framework draft for IFIT and this is what I found.

I think a framework draft for IFIT solution should be addressed in the
draft in the introduction.

I noticed that there are a number of ifit related drafts across many WGs
with a variety of authors and it appears no common author across all the
documents.

Is there an IFIT framework draft of the overall IFIT architecture and goals?

IFIT is a component of IPPM IOAM but I think it should have its own
framework draft.

I did find this IFIT framework draft which I don’t see as informational
reference in this document.

https://datatracker.ietf.org/doc/draft-song-opsawg-ifit-framework/

Of all the IFIT related drafts I do see one adopted.

Re: [Pce] WG Adoption of draft-li-pce-pcep-pmtu-05

2022-04-22 Thread Gyan Mishra
Dear PCE Chairs

After the discussion thread with Ketan we are now in sync and I have agreed
to work with the authors of the IDR and PCE draft in a collaborative effort
 on publishing a draft in SPRING WG that addresses PMTU in SR Policy and
Fragmentation in SR policy.

I have discussed with the PCE authors that I agree that PMTU in SR Policy
definition and SR Policy and fragmentation should be in a Spring Standards
Track draft from an implementation standpoint to avoid any interoperability
issues in proprietary vendor specific definitions of PMTU in SR Policy.

Anything SR architecture related which PMTU and fragmentation in SR policy
are part of the SR architecture which is why it belongs in Spring.

We have reached an agreement that the PCE draft can proceed for Adoption
and once it becomes a WG document we will ensure that protocol specific
encoding is only included in the PCE draft with informational reference to
the new Spring PMTU draft that has the detailed framework of PMTU in SR
Policy specification.

Ketan has offered to help in editing the new draft.

As well if anyone else in Spring or PCE would like to collaborate on the
draft please let us know.

Kind Regards

Gyan

Gyan> I reviewed the mail archive on the discussion and your request
for a PMTU in SR policy Spring document.  I think this is an important

Would this draft go into the details of how fragmentation would work with

and PCEP  solution?  If the authors of the PCEP draft published an
informational draft on PMTU in SR Policy as it relates to both IDR and PCE

Re: [Pce] WG Adoption of draft-li-pce-pcep-pmtu-05

2022-03-28 Thread Gyan Mishra
Hi Dhruv

I reviewed the draft and support WG adoption.

Should this draft be adopted by the PCE WG?

Yes

Please state your reasons - Why / Why not?

This documents PCEP PMTU extension is valuable for any operator deployments
of SR-MPLS or SRv6 and/or uses SR-TE and want to ensure that fragmentation
does not occur along the stateful path instantiated.

What needs to be fixed before or after adoption?

The document well written and to the point and is ready for adoption

Are you willing to work on this draft?

Yes I would be happy to collaborate on the draft

Review comments should be posted to the list.

Few comments for the authors below:

It maybe worthwhile to mention PMTUD path MTU discovery which allows a TCP
session to dynamically adjust the MSS for incoming and outgoing MSS.  As
this document utilizes PMTU which is based on the PMTUD concept which is
being carried in a new metric field in the PCEP report message I think for
clarity it would.

BGP uses TCP and by default most all vendor implementations have PMTUD
enabled by default on all BGP sessions.  Maybe worthwhile mentioning.

In the abstract I don’t understand this sentence.

Since the SR does not require signaling, the path maximum
transmission unit (MTU) information for SR path is not available.


I understand SR eliminates the control plane signaling for label
distribution LDP which is now via IGP extension, but how does that make it
so the SR MTU information is not available.  Directed LDP is for adjacency
nodes or targeted LDP for session protection for non directly connected
nodes.

RFC 5036 LDP does not support signaling for MTU.

RFC 7552 LDP updates for IPv6 also does not support signaling for MTU.

RFC 3988 is an experimental extension to support signaling for MTU.

I see RFC 3988 as a informational reference.

I think it would be good to mention what I stated above related to LDP not
providing any signaling for MTU and RFC 3988 as its experimental and not
standard track also not implemented by all vendors.

Section 3.5 mentions that path MTU adjustment can be made for primary or
TI-LFA local protection path.

I would think this can be used for SR-TE protected path instantiated by
stateful PCE but not for local protection.

Also would this draft be applicable to Non SR MPLS and GMPLS LDP signaling
RFC 3988 is experimental only so MPLS and GMPLS as well have a gap for MTU
signaling.  I do see you stated in the introduction.  You may want to state
the gap that exists as RFC 3988 is experimental and now this solution fills
that gap as well.


Thanks

Re: [Pce] WGLC for draft-ietf-pce-vn-association-05

2022-03-16 Thread Gyan Mishra
Dear WG

I read the draft and support publication.

This document specifies a PCEP extension to associate a set of LSPs to a
newly defined VN association Group (VNAG).

Dear Authors,

Does this draft update RFC 8697 or any other PCEP RFC?

Thanks

Gyan

Re: [Pce] draft-dhodylee-pce-pcep-ls next steps!

2021-07-18 Thread Gyan Mishra
Hi Siva

Many thanks for your support and responding to WG poll sent for interest in
progressing research and development efforts of this work as as an
experimental draft.

Yes that is one of the main R=0 goals and use cases to be able to reuse the
existing PCECC CCI object SDN (SDN-like) SBI session for PCEP-LS, thereby
eliminating the needs for another protocol in this case BGP-LS NBI for that
purpose.  That is the main goal and use case and very nicely pointed out
Siva.

This draft does provide the nice flexibility as well if operators are not
yet using PCECC for R=1, to allow for mixed environments and cater to the
operators needs and requirements.  We want to emphasize that we are not
trying to by any means compete with the other existing solutions but rather
provide operators another valuable tool in the operators toolbox.

As part of the next steps in building the framework for the scope of the
experiments performed the to prove out any scalability concerns and impact
to other protocols namely the reuse aspect of the SBI.

We would like to prove out that this solution is solid and viable in the
tests and that the reuse of the SBI in fact provides improves scalability
rather than diminishing scalability by leveraging the R=0 existing sessions
between all nodes versus PCEP PCE R=1.  We would also like to prove out in
the experiment that we are in fact not overloading the SBI by the reuse for
PCEP-LS and in no way impacting the existing SBI PCECC PCE session.

We would like to address in the experiment any and all scalability,
overload, collateral damage related issues  or any fear or issues anyone
has to prove that this is a solid and viable solution on par with the other
existing solutions as an extra tool in the operators toolbox.


Kind Regards

Gyan

[Pce] draft-dhodylee-pce-pcep-ls next steps!

2021-07-05 Thread Gyan Mishra
Dear PCE WG,


We presented the PCEP-LS [1] I-D [2] in the IETF 110 with a quick recap and
a summary of past discussions. Some new scenarios such as PCECC, H-PCE were
highlighted where the PCEP session could be reused.


This is an experimental I-D with the aim to progress research and
development efforts. This work is not a replacement for any of the existing
mechanisms. There are specific scenarios highlighted where the reuse of
PCEP sessions for this information is deemed useful. To make progress, it
may not be useful to rehash the beauty context between everyone's favorite
protocol :). What would be useful would be - finding out if there is still
interest in this experimental work by some in the WG; are there strong
technical objections for the experiment in its limited scope etc...


As a next step, it would be good to define the scope of the experiments and
expected output especially targeting the scalability concerns as well as
impact in other protocols and the network, etc.


>From the last query on this draft March 18th we received positive feedback
from Aijun Wang with China Telecom mentioned that as a telco are interest
in deploying in their network PCEP-LS once the Huawei implementation is
ready.  Aijun pointed out in the thread that using this draft simplifies
the implementation of SDN controller.  One question asked by Aijun was
related to section 9.2.1 LS Capability TLV R=1 remote allowed meaning
hybrid mode to provide flexibility for operators not yet using SDN
(SDN-like) SBI.  For any operators already using PCEP as SDN (SDN-like)
SBI, a direct PCEP session already exist between all the nodes in the
network and the PCE which would be the PCECV SDN scenario in which case the
R flag in the open message is set to 0.


We also received positive feedback from Peter Park with telco KT regarding
interest in PCEP-LS.


We also had feedback from Bin as they have implemented PCEP and have
interest in this experimental implementation of this work.


I would like to poll the WG again for interest in progressing research and
development efforts of this draft as experimental.


As stated in the last WG poll, I would like get feedback from the WG on
scope of experiments especially related to scalability concerns and impact
to other protocols on the network.


Thanks!

I support WG adoption of this important draft for instantiation of  ECMP
multipath by encoding multiple segments lists of an SR candidate path.

Hi Peter

That’s good to hear interest from operators such as yourself in PCEP-LS.
As you deploy PCECC and H-PCE in a multi domain environments you will be
able to reuse the SBI PCEP session for PCEP-LS and then can take full
advantage of some of benefits of PCEP-LS such as synchronization
optimization and incremental updates.

Thank you for sharing your interest in PCEP-LS.

Kind Regards

Gyan

Understood.  I-D covers only BSID control plane handling for both RSVP-TE
and SR-TE

However, for RSVP-TE their is only a control plane component where SR both
control and data plane of which the SR-MPLS and SRv6 data plane is handled
in SPRING/MPLS/6MAN.

Is the usage for BSID only for control plane signaling as I described it.

What other use cases exist and maybe we should add to the draft.

Re: [Pce] WG Last Call for draft-ietf-pce-binding-label-sid-07 (and Code Point Allocation)

2021-03-28 Thread Gyan Mishra
Hi Siva

I believe  I was missing the signaling aspect for the PCE to build the
contiguous end to end LSP and that requires BSID to be signaled over
RSVP-TE which is although agnostic to data plane BSID component binding the
candidate path to the forwarding plane, is a requirement for end to end
control plane signaling for the single LSP end to end path instantiation.

The BSID signaling concept is somewhat analogous concept to LDP tunneling
over RSVP-TE tunnel stitching for an end to end LSP instantiation.

Thank you Siva for the clarification.

Re: [Pce] WG Last Call for draft-ietf-pce-binding-label-sid-07 (and Code Point Allocation)

2021-03-28 Thread Gyan Mishra
All

After further review with Siva the use case is for connecting SR islands
over RSVP-TE core.

So this is for stitching SR-TE on the edge islands binding SID to core
RSVP-TE tunnel.

One major gap  of RSVP-TE is the VRF / VPN coloring capability that in
order to achieve per VRF coloring mapping of VRF to a discrete TE tunnel
requires a separate loopback and static routes to egress PE so it does not
scale.  So for as many RSVP mapped tunnels that exist you need that many
loopbacks and static routes for the next hop rewrite to the RSVP tunnel
next hop.

So this Major gap is filled with SR VRF and app flow coloring capability
that with SR-TE Policy BSID bound to candidate path can provide the
scalability per VRF coloring.

So at the edges you may have many 100s of colored RSVP tunnels but as the
core does not scale you can not provide a 1-1 mapping of SR-TE tunnel to
RSVP tunnel.  So you would have many to 1 mappings of SR-TE tunnels to
single or aggregate.

So in my mind to only way the BSID would come into play is if you could do
a 1-1 mapping of SR-TE tunnel to RSVP tunnel.  Technically that is not
possible.

For PCE to compute end to end path in this scenario does RSVP-TE require
the BSID for the stitching even if a many SR-TE colors to single RSVP-TE
tunnel mapping. I would not think so.

If we think that for PCE to build the end to end path even for the end to
end path in this scenario requires BSID binding to the RSVP-TE single path
to make contiguous end to end then I agree technically we do need to make
this inclusive of RSVP-TE.

I think we need to clear this up and if this use case is really not
feasible then we should remove any mention of BSID use with RSVP-TE tunnel.

Kind Regards

[Pce] draft-dhodylee-pce-pcep-te-data-extn

2021-03-17 Thread Gyan Mishra
Dear PCE WG,

We presented the PCEP-LS [1] I-D [2] in the IETF 110 with a quick recap and
a summary of past discussions. Some new scenarios such as PCECC, H-PCE were
highlighted where the PCEP session could be reused.

This is an experimental I-D with the aim to progress research and
development efforts. This work is not a replacement for any of the existing
mechanisms. There are specific scenarios highlighted where the reuse of
PCEP sessions for this information is deemed useful. To make progress, it
may not be useful to rehash the beauty context between everyone's favorite
protocol :). What would be useful would be - finding out if there is still
interest in this experimental work by some in the WG; are there strong
technical objections for the experiment in its limited scope etc...

As a next step, it would be good to define the scope of the experiments and
expected output especially targeting the scalability concerns as well as
impact in other protocols and the network, etc.

Thanks!

I support WG adoption by the PCE WG.

I agree with Dhruv that maybe we should limit TLV to LSP object only.  I
don’t mind complexity if their is a significant gain with making it
generic.  I think we have to weigh the pros and cons.

Thanks

Reviewer: Gyan Mishra
Review Date: 2021-02-10
IETF LC End Date: 2021-02-08
IESG Telechat date: 2021-02-25

Summary:
This document is very well written and describes a new PCEP protocol extension
for using PCE as a centralized controller PCECC for provisioning using its own
discrete label space for all or discrete parts static LSP ERO path.

Major issues:
None

Minor issues:

For stateful PCE how do you prevent label collisions when both the PCE is
provisioning using its own label space and the routers also are using their own
label space as well and have a mix of both.  After the label download and sync
at each router hop PCE PCC session their maybe some nodes that use the router
label space  and other nodes using PCE label space.

It would seem more complicated to have a mix of having both PCE managed label
space and non PCE managed label space and for this draft since it’s about
provisioning static LSP using PCE discrete label space I think it would make
more sense to have entire LSP to be provisioned using PCE label space to
prevent label collisions.  This caveat I think should be added to the
considerations section as well.   I did not see it mentioned but I think it’s
also worthwhile mentioning what is the advantage of using this extension where
the PCE uses its own label space.  Also list the disadvantages as well so the
operator had a clear picture of reasons to use this extension and maybe reasons
to not use.  It maybe also worthwhile to mention use cases where it makes sense
to use this extension and others where it is not.

In section 9 I agree it’s a good idea to have mutually authentication and
encrypted sessions for all PCE PCC sessions to prevent malicious PCE using this
extension.

Nits/editorial comments:
The abstract states the following in the last sentence which I think should
better describe the goal and purpose of the draft.

“ This document specifies the procedures and PCEP extensions for using the PCE
as the central controller.”

I would say use of PCE as a centralized controller for provisioning RSVP-TE or
SR-TE static LSP explicit ERO path for all or parts of an LSP using its own
discrete label space.

Re: [Pce] PCE Controller & SDN Controller & Netconf/Yang NMS Controller - lines blurred and can the names be used ubiquitously meaning the same

2020-10-12 Thread Gyan Mishra
All

Another way of looking at BGP-LS is that it is an extremely powerful tool
for centralized controller based architectures or hybrid architectures, and
it does not bog down or impact the agility and lightweight aspects of BGP,
as BGP has its overall ability to stack & pile on SAFI's and codepoint's as
necessary to meet the desired design objectives.  So BGP can still remain
as light weight or as heavy weight as desired based on the design objective.

! BGP LS IAIA codepoints
https://www.iana.org/assignments/bgp-ls-parameters/bgp-ls-parameters.xhtml

So its safe to say that the use cases are pretty limitless for BGP-LS from
PCE path instantiation to ZTP & Day X provisioning & configuration.  I
think "dump drunk" depiction of BGP-LS is really a negative perception, as
BGP-LS has the native data structures primitives to build customizable
TLV's to meet almost any design objective.

Comments welcome.

Kind Regards

Gyan

[Pce] PCE Controller & SDN Controller & Netconf/Yang NMS Controller - lines blurred and can the names be used ubiquitously meaning the same

2020-10-10 Thread Gyan Mishra
Dear TEAS, PCE, IDR, LSR, BESS, BIER  Spring Working Groups,

I have noticed that after reviewing many drafts across many WGs it seems in
the industry that the lines seem to be blurred between a PCE controller,
ODL or Openflow SDN Controller and a Netconf/Yang NMS Controller ZTP & Day
X provisioning.

As this is a software sitting on a server you can have a swiss army knife
server that does everything from PCE path computation to  Netconf/Yang ZTP
& Day N provisioning as well as any SDN Controller ODL or Openflow
controller type functions as well.

How this comes into play and realization of the lines being blurred is the
use of BGP-LS in building the IGP topological graph of the network which
was designed for PCEP and PCE & PCC active & passive off line path
computation for both RSVP-TE or SR-TE path instantiation.

However now BGP-LS can also be used for other functions now such as usage
as I am a Shepherd reviewing a draft for BGP-LS usage for BIER to use
BGP-LS to gather the elements internals within BIER using the same BGP-LS
data structures to populate with BIER specific information to graph the
BIER topology.  So here we are not doing any path computations as we are
using in this use case  for NMS type function to gather data for ZTP & Day
N provisioning.

Similarly other use cases such as with TEAS TS-Transport slice and being
able to provision TS and capturing the TS Enhanced VPN RT & resource
information and leveraging BGP-LS to do the same data gathering & ZTP like
controller style provisioning.

It does seem as though BGP-LS as its a means of "data gathering" "dump
truck" of anything with the kitchen sink included to build any type of
topological graph of literally anything under the sun.  I see that is a
nice to leverage but it does in fact blur the lines of NMS Netconf/Yang
Controller based functionality and  PCE path computation functionality and
SDN controller based ZTP functionality into a single ubiquitous server that
can do all of the above and use BGP-LS to accomplish the "kitchen sink"
tasks.  It does however transform BGP to be an NMS tool but a "tool" and
not just the original function which it was intended NLRI network
reachability.

Am I off base and please let me know as its BGP-LS is being way over
leveraged.  There are pros & cons to everything but I thought I would bring
up to the WG as an important discussion point.

Lots of food for thought.  Welcome all comments as well as concerns related
to this topic.

Kind Regards,
