Room: Salon H

Tom Scholl, AT&T Labs

Within the Global IP/MPLS backbone design & development team, his role is to design routing architectures for the core network and work on network integration of the legacy SBC Internet Services network to the AT&T common backbone. Tom has spent his last several years at SBC and Ameritech working in both operations and network engineering roles. He has presented several times at NANOG and always makes time available to help peers and distribute clue where needed.

Richard Steenbergen, nLayer Communications

Richard Steenbergen is the co-founder of nLayer Communications, a respectably sized and profitable North American based IP backbone, where he currently serves as the Chief Technical Officer. Richard brings years of experience in practical techniques for network operators, and is a frequent contributor in many community forums. Previously, Richard served as a Senior Network Engineer at several large NSPs, and was the Senior Software Engineer responsible for developing optimized routing technologies at netVmg, Inc.<BR> <BR> Richard is also an active developer for tools and software used by the network operator community. Some notable projects include PeeringDB, a portal used by many networks to help coordinate their peering activities, and IRRPT, a software package used by ISPs to maintain IRR-based prefix filters.
Abstract: This presentation covers proposed method to combine BGP and MPLS-TE to avoid congesting peering or transit links. The idea is to include MPLS-TE bandwidth reservation in the BGP best-path decision process in order to select alternate paths which have sufficient capacity. This behavior is currently executed today by manual policy modification by an operator. An operator typically has to move traffic around carefully while waiting further capacity upgrades. This ideally could work in two different scenarios. One example would be where you have multiple links to a peer and you wish to move traffic to another peering location with that particular peer. Another scenario allows you to avoid routing to a particular peer and route to them via a separate peer/AS-Path. This would be useful when you wish to keep traffic "local" (not have to haul it) and are willing to send it to another peer/transit provider.
