Hello everyone
In the context of a single service provider network running MPLS, if a
number of bandwidth constrained LSPs are passing through a particular node
and the sum of the bandwidth constraints for the LSPs is X Mb/s, then is X
the upper bound on the traffic through that node, or is it
Well, yes (if you don't count the additional traffic of signalling/routing
protocols, label imposition, etc) but consider the fact that topologies
change and routing will tend to change the total traffic handled through a
node. LSPs are not static unless you use TE tunnels. Remember that labels

Thanks for the reply. You say that LSPs are not static unless you use TE
tunnels. Are you referring to the staticness in terms of the path or in the
amount of bandwidth reserved on each link along a fixed path determined at
the time of signalling? Isn't a bandwidth constrained LSP always a
Anyone home with BGP/Routing access? I opened a ticket last Friday. As a
gigabit ethernet customer with a rather simple problem on your end of the
BGP config, it'd be nice to actually get some kind of response beyond

BTW...either
Furthermore, I was also wondering, if the bandwidth constraints are upper
bounds, what does the traffic distribution typically look like at an LSR?
We're interested in traffic within a single service provider, non-Internet
traffic. Perhaps most service providers set aside some (dynamic?) pool for

That should work then, and a reasonable solution for not having to
sign up for a third party service.

Dedicated servers are cheap and you can maintain control of the content.

Hello all,
I was wondering how many of you use route flap dampening in your network.
If you have it enabled, what is the main reason?
Thank you!

We've been considering it after the last flap around the world; perhaps
with extremely short penalty times.

I'm in the hunt for 3-4 AC to DC power supplies and was wondering if
anyone has a brand / part they suggest.
Basically, we only have AC power in my building but need to stage and

staged require -48VDC and a

Update: Qwest did not appear to be affected by this,
Just got off the phone with ATT MIS Support - there is some extremely
large facility outages in the Southern California area. I'm seeing
T1-OC3 facilities down from San Diego to Los Angeles to Riverside to
Palm Springs.
We've seen voice, data, legacy ATT and legacy SBC/PacBell circuits
affected.
Confirming outages in SoCal area affecting ATT (lost a large circuit
out there @ 1:24 PDT). I should add not all SoCal sites are affected,
just some.

Looks like Level3 at this point, not Qwest. Some traffic wasn't getting to
us, which caused the dip in our outbound. It lasted about an hour.
