 Hello,

 This should also work and can be customised however you want:

 I did add a test version at http://atl.ezeea.com/rotate.html just to check

 Just wondering if anyone can recommend Windows software (it could be

 It would be nice if it was freeware or open source but whatever works
 best is what I am looking for.
 For example, if I wanted one monitor to cycle thru my local SolarWinds
 Orion, Office 365 Health Status, and anyother webdashboards.

IETF contacts? - Fwd: Reference to historic or obsolated RFCs

2012-08-06 Thread Livio Zanol Puppim
Hello guys,

I've sent the e-mail below to IETF, but I couldn't find a contact e-mail to
address this kind of subject in IETF site. Does anybody knows which e-mail
to send this?

The contact page from IETF website:
http://www.ietf.org/contact-the-ietf.html

-- Forwarded message --
From: Livio Zanol Puppim livio.zanol.pup...@gmail.com
Date: 2012/8/6
Subject: Reference to historic or obsolated RFCs
To: ietf-i...@ietf.org, ietf-act...@ietf.org


Hello,

I don't know which contact to send this e-mail, so I'm copying the INFO and
ACTION e-mail... If these are the wrong contact, can you please point me
the correct e-mail?

Reading the *RFC 5375* I've found references to some RFCs that are
considered Historic, or have been updated. In some cases, this can lead to
a misunderstand of a a section in a RFC.

For example:
The* RFC 5375* in section *B.2.2* states that we should avoid using /127
IPv6 prefix, but* RFC 6164* clearly says that we can use /127 prefix for
Inter-Router links. In fact, the *RFC 6547*, moves the *RFC
3627*(referenced by the
* RFC 5375* in the above section) to Historic status.

If my point of view is indeed correct, I think that everytime a new RFC is
published that proposes an *Update* to another RFC, or *Obsoletes* another
RFC or moves a RFC to *Historic *status, the team responsible for it's
creation needs to read every reference to that RFC and request changes in
order to avoid this kind of misunderstanding. This is very important to
guys like me, that only reads the RFCs.

the section from RFC 5375
http://tools.ietf.org/html/rfc5375#appendix-B.2.2




B.2.2 http://tools.ietf.org/html/rfc5375#appendix-B.2.2.  /127 Addresses

   The usage of the /127 addresses, the equivalent of IPv4's RFC 3021
http://tools.ietf.org/html/rfc3021
   [RFC3021 http://tools.ietf.org/html/rfc3021], is not valid and
should be strongly discouraged as
   documented in RFC 3627 http://tools.ietf.org/html/rfc3627
[RFC3627 http://tools.ietf.org/html/rfc3627].

Re: Network diagram app that shows realtime link utilizatin

In a troubleshooting situation I think real time is valid. Off course, is
non-sense doing this for normal monitoring...

But firstly define: What's real-time? every second? miliseconds? 10

 Utilisation doesn't become 100%, instead measured utilisation will

DWDM Metro Access Design

2011-03-21 Thread Livio Zanol Puppim
Hello,

I don't know if this is the appropriate list for this kind of subject, so if
anyone knows another specific list, please tell me...

I'm analysing several DWDM designs to implement at my city, but I'm still a
bit confusing about the Metro acess design. I'm supposed to build a physical
ring topology with 6 pairs of fiber with an hub-and-spoke logical topology.
The ring will have about 40Km. At the HUB we'll install our
point-of-presence with a MPLS equipment, and at the spokes we'll use only IP
routers. We need an flexible design where we can add or remove spokes as
needed with the minimum effort possible. We are planning to have, at a
initial deployment, about 200 hundred spokes, and all these spokes are
talking only with the HUB site. Everything should work like in an FTTH or
FTTB design, no other type of transportation is allowed (wireless and
copper).

We can't use SONET/SDH. The solution must be only IPoDWDM or complemented
with TDMoIP at the access equipment.

The problem, is that all documents that I'm reading specifies that we should
be worried with faults scenarios at the spokes, so that the optical network
does not stops. For example, if the OADM equipment at the spoke is down, the
lambda dropped at that site will be down too... Or at least, if we use a lot
of lambdas, we need to keep and eye at the points where we have
regenerators.

We need bandwidth from 10Mbps to 1000Mbps at these spokes.

My question is:
Is it possible to make such a network in a way that we don't need to worry
about faults (electrical or others) at the spokes? If so, how can I do this?

I don't want the spokes sites interfering directly at the operation for the
whole network.

Thanks for your help.

Re: DWDM Metro Access Design

2011-03-21 Thread Livio Zanol Puppim
I don't rally care about the uptime at the spokes. It's not my
responsability to maintain the spokes sites, we'll just give communication
to our network.

I know that I'll have single point of failure in my topology, like having
just one HUB, but I just don't want a spoke interfering in the opeartion of
my network. Ex.: I don't want a eletrical failure at one spoke interfering
in the operation of other spokes...

Thanks for your reply. :)

 Hello Livio:

 At some point you will have a single point of failure, it's just a matter
 of where.  If you are running a single-threaded lambda or set of them into
 a spoke site, that node will go down should your transport gear fail.  If
 you want your add-drop sites to be redundant through the network layer you
 will have to feed each spoke site from the East and West side of your ring
 on separate add-drop gear.

 That will be expensive.  If price is no object, you can do that and then
 use your upper layer protocols to determine path availability.  Or, you
 can build your add drop site with a single device and built-in redundancy
 (controller cards, power supplies, etc.) to keep the cost down.

 Long story short, if you need those sites to stay up regardless of
 anything else, you have to build two of everything at each site.  It can
 certainly be done and many a vendor would like to talk to you about
 solutions I'm sure!  :-)

Re: Network management software with high detailed traffic report

2010-11-22 Thread Livio Zanol Puppim
IT depends on the manufacturer. Cisco can updates OIDs even on 1 second time
basis (maybe less?).

A long time ago I've made an real time monitor to troubleshooting problems
at the WAN. IT was not a NMS, only visual graphs using PHP and RRDtool in
one page showing IfOctests, IfDiscards, IfErrors, IfNUnicast and, in some
cases, BECN and FECN for frame relay.

 Steinar,

 I'm sure that router updates its counter more often than 5 seconds.
