Hi,

This is just a reminder that Alia will be giving a talk on next
week's NRG (Monday February 28th). The talk will be held at MCS135
at 4:00pm.

Subject: [Nrg-l] Alia Atlas on IP Fast-Reroute (next Monday)

Folks, 

We will resume our NRG meetings this spring with a talk by Alia Atlas
(see below). Alia is not a stranger to our group as she got her PhD in
1999 (working on statistical real-time scheduling among other things).
Alia is one of the leading technical principals at Avici Systems, which
she joined at its formative stages from BBN.

Title: IP Fast-Reroute: An Analysis of Applicability to a Core Network 

Speaker: Alia Atlas (Avici Systems) 

Abstract:

IP Fast-Reroute can provide resilience in the event of a failure by
quickly (<50ms) rerouting traffic to pre-computed alternates. The basic
mechanism of loop-free alternates is described; candidate advanced
methods are also discussed. The related problem of avoiding
micro-forwarding loops during network convergence is described. Two
mechanisms for micro-forwarding loop prevention - path locking via safe
neighbors and Ordered FIB installation - are presented. 

The applicability of IP Fast-Reroute as applied to a particular core
network is analyzed. This analysis considers loop-free alternates and
U-turn alternates. The analysis examines both the effectiveness of the
techniques on the various network topologies and the capacity planning
implications of using IP Fast-Reroute. 

Joint Work with Gagan Choudhury (AT&T)
