Re: [Pce] Call for slot in the PCE WG at IETF 117

2023-07-09 Thread Dhruv Dhody
Hi WG,

There have been cases of missing emails to the chair's alias <
pce-cha...@ietf.org>. I am maintaining the incoming slot requests at
https://notes.ietf.org/PCE-Agenda-IETF117?view ; in case you made a request
and you dont see it on the list please send an email directly and not with
the alias.

Thanks!
Dhruv

[Pce] I-D Action: draft-ietf-pce-pcep-extension-pce-controller-sr-07.txt

A New Internet-Draft is available from the on-line Internet-Drafts
directories. This Internet-Draft is a work item of the Path Computation
Element (PCE) WG of the IETF.

   Title   : PCE Communication Protocol (PCEP) Extensions for Using PCE 
as a Central Controller (PCECC) for Segment Routing (SR) MPLS Segment 
Identifier (SID) Allocation and Distribution.

   Pages   : 34
   Date: 2023-07-08

Abstract:
   The PCE is a core component of Software-Defined Networking (SDN)
   systems.

   A PCE-based Central Controller (PCECC) can simplify the processing of
   a distributed control plane by blending it with elements of SDN and
   without necessarily completely replacing it.  Thus, the Label
   Switched Path (LSP) can be calculated/set up/initiated and the label
   forwarding entries can also be downloaded through a centralized PCE
   server to each network device along the path while leveraging the
   existing PCE technologies as much as possible.

   This document specifies the procedures and PCE Communication Protocol
   (PCEP) extensions when a PCE-based controller is also responsible for
   configuring the forwarding actions on the routers, in addition to
   computing the paths for packet flows in a segment routing (SR)
   network and telling the edge routers what instructions to attach to
   packets as they enter the network.  PCECC as defined in RFC 9050 is
   further enhanced for SR-MPLS SID (Segment Identifier) allocation and
   distribution.

[Pce] I-D Action: draft-ietf-pce-stateful-pce-optional-06.txt

2023-07-09 Thread internet-drafts


A New Internet-Draft is available from the on-line Internet-Drafts
directories. This Internet-Draft is a work item of the Path Computation
Element (PCE) WG of the IETF.

   Title   : Extension for Stateful PCE to allow Optional Processing of 
PCE Communication Protocol (PCEP) Objects
   Authors : Cheng Li
 Haomian Zheng
 Stephane Litkowski
   Filename: draft-ietf-pce-stateful-pce-optional-06.txt
   Pages   : 12
   Date: 2023-07-08

Abstract:
   This document introduces a mechanism to mark some of the Path
   Computation Element (PCE) Communication Protocol (PCEP) objects as
   optional during PCEP messages exchange for the Stateful PCE model to
   allow relaxing some constraints during path computation and setup.
   This document introduces this relaxation to stateful PCE and updates
   RFC 8231.

A New Internet-Draft is available from the on-line Internet-Drafts
directories. This Internet-Draft is a work item of the Path Computation
Element (PCE) WG of the IETF.

   Title   : Inter Stateful Path Computation Element (PCE) 
Communication Procedures.
   Authors : Stephane Litkowski
 Siva Sivabalan
 Cheng Li
 Haomian Zheng
   Filename: draft-ietf-pce-state-sync-05.txt
   Pages   : 35
   Date: 2023-07-08

Abstract:
   The Path Computation Element (PCE) Communication Protocol (PCEP)
   provides mechanisms for PCEs to perform path computation in response
   to a Path Computation Client (PCC) request.  The Stateful PCE
   extensions allow stateful control of Multi-Protocol Label Switching
   (MPLS) Traffic Engineering (TE) Label Switched Paths (LSPs) using
   PCEP.

   A Path Computation Client (PCC) can synchronize an LSP state
   information to a Stateful Path Computation Element (PCE).  A PCC can
   have multiple PCEP sessions towards multiple PCEs.  There are some
   use cases, where an inter-PCE stateful communication can bring
   additional resiliency in the design, for instance when some PCC-PCE
   session fails.

   This document describes the procedures to allow a stateful
   communication between PCEs for various use-cases and also the
   procedures to prevent computations loops.
