Re: Aggregate traffic management

2003-01-28 Thread Kyle C. Bacon

Take a look at a product called "Path Control" by RouteScience.

http://www.routescience.com/

I have seen their product in action and it is very slick.  Does exactly
what you want,
plus a whole lot more and does it transparently (so if it fails you aren't
SOL) via
manipulating BGP tables and nexthop based on a multitude of criteria.

Dear NANOGers,

I have a very hands-on question:
Suppose I am a network operator for a decent-sized ISP, and I decide
that I want to "divide" aggregate traffic flowing through a router
toward some destination, in order to then send some of it through one
route and the remainder through another route.  Thus, I desire to
enforce some traffic engineering decision.

How would I be able to accomplish this "division"?  What technologies
(even if vendor-specific) would I use?

I can think of some methods like prefix-matching classification and
ECMP, but I am still not sure exactly how the latter works in practice
(at the router level) and how one may set them up to achieve such
load-sharing.

Thank you for your expertise and lore,

Re: Cogent issues at AADS PVC 5.34?

2002-07-22 Thread Kyle C. Bacon


We received notification this morning that there were some problems with at
least one of the ATM switch cards @ AADS.  If it is getting
worse, lets hope they fix it before their scheduled maintenance (this next
weekend).

SBC/Ameritech NAP customers,

We have been experiencing problems with the card that your circuit resides
on.   We are planning to swap it out on Sunday, July 28th at 12:01AM CST.
With that you will experience a short outage.

Thanks for your patience.

We're currently experiencing significant latency through Cogent at AADS.
 I've heard they have some general latency issues, but nothing concrete
yet as to what and where.  Does anyone have any details of any problems
while we're waiting for a response back from the NOC?  Thanks,

John

Maybe some of the telco's are finally learning that the quicker you can
install, the sooner you can bill.  :)

We always hear the worst but I just thought I would plug Qwest in that they
just installed an OC-12 point to point cross country for me in 27 hours
from
time of order.  This included cross connects at Level3.

We have two POP's and a colo in Detroit.  One in Southfield, one in Troy,
both on the North side of Detroit.

If anyone is looking for reliable access from a profitable regional player,
I'll volunteer.  :)

As far as I know, the following national providers exist in Detroit:
(This is by no means, a complete list, and some of these aren't "Big
Name" providers, but less likely to go under than John Q Random ISP)

Verio
Winstar
XO
AT&T
Qwest
Covad
Level 3
SBC
I've heard rumors of speakeasy.net, which I think resells internap

I'm sure there's a few other national networks, these are just the ones
I have heard of off the top of my head.
