Simon,
You missed the question. Timothy is interested in finding companies who have
deployed the latest generation of edge devices. These devices specialize in
QoS, VPNs and more intelligent(CPU intensive) features. A GSR is not in the
same classification since this router is meant for the core. Vendors
competing in the edge space are Shasta, Ennovate, Cosine and Unisphere to
name a few.

Hi, just piping up for myself a little bit.
Yes, Chris is correct. I am interested in the VSR 15K as a non-core device
(e.g., distribution) for regional hub(s). There is no particular reason I
could not use a Cisco GSR. Perhaps it is best to make it clear what I am
looking for.
I want a chassis-based solution able to provide regional connectivity to a
number of access-level routers. There is a need to provide incredible density
(well, incredible for me, but I don't run a big network) over disparate access
technologies (frame, E-1/T-1, ATM). I don't have a very solid understanding of
many optical technologies just yet, but I am under the impression I can lay my
own dark fiber and put some sort of box on either end, not necessarily a VSR
15K, and run data across it without any telco intervention. Cisco has a line
card (apparently for the GSR) which supposedly does this, their OC-48/STM-16
bidirectional regenerator. Requirements for the chassis-based solution are the
ability of the company providing it to encrypt the data passing over the line
(including such things as routing updates, etc). I know this sounds weird, and
I may not be explaining it all properly. The box has to rock-solid - you can
assume I will be placing it somewhere where I can't go and fix it every time it
breaks. In the past, I have understood that Cisco's reliability record on
devices doing "weird things" has been better than Nortel's.
So, the questions are:
- Does it break under real production loads?
- Is Nortel's engineering team the type to do custom solutions?
(e.g., I provide encryption, they integrate it into their code?)
- Can it terminate(?) dark fiber?
- Does it speak everything it has to? What about non-IP traffic?
- Is the GSR a better solution?
- Is there any other box that can terminate a ghastly amount of
frame, T-1/E-1, DS-3, and OC-48+ circuits?
Regards,
Timothy
You cannot terminate OC-48 directly into the Versalar 15k. Its OC-12 and OC-12c.
I'm not finding my notes as to whether there is an Oc-12 card on the access side.
I recall an OC-3 access card (note, I refer to channelized not concatenated).
Certainly DS-3.
I have been told that it has been tested with 256 BGP peers in a mix of internal and external.
V15k was built for the edge of the network, but has been used for core by some because
there isn't anything bigger from Nortel until V25k release. V25k will eventually take OC-48
ATM. I believe it starts with WDM.
If you do not find the answers you need, I can point you at someone inside Nortel
Networks who has the answers and probably customer references.

Hello all,
Background:
I am the platform architect of a new, very high projected volume, web-site.
Initial troughput numbers are greater than 1Gbps with a TB of online disk
space. Initial site-backbone capacity is expected to exceed 5Gbps. Thois
includes both HTML and streaming multi-media content. Projections are
estimated to increase radically on commencement of service. Some of your
organization will be approached, by the General Contractor, within the next
few months. We will issue an RFP in 1Q2000. I am not at liberty to reveal
more than this at the moment.
What I need are links to vendors that provide instrumentation for multi-Gbps
backbones (aggregated 1000baseSX), local directors, and firewall support
(yes, I know about Checkpoint). Can some of you help me out here? What have
you used and what works, as well as what doesn't?
Please respond in private e-mail or the on-topic wardens will cast a hex on
me <grin>.
BTW, I also need (later) a list of providers that have a substantial "dark
fiber" network and can support cold-potato routing options. We will need
colo space with multi-Gbps feeds (Cisco 6500 series, our end).
