NANOG Meeting Presentation Abstract

Source Routing 2.0. Why Now, Why Again?
Meeting:	NANOG64
Date / Time:	2015-06-03 11:30am - 12:00pm
Room:	Grand Ballroom
Presenters:	Speakers: Nick Slabakov, Juniper Networks Nick Slabakov is Chief Architect for the Web Services group, where he works with some of Juniper's most innovative customers on solutions to the challenges of scale, programmability, and efficiency in their networks. Nick’s recent work and industry involvement spans the areas of MPLS-TE, SPRING, SDN, Cloud Networking, and Network Automation / Programmability. His previous roles in Juniper included various Systems Engineering positions supporting Tier 1 carriers. Prior to Juniper, Nick was a Principal Systems Engineer at Riverstone Networks, which followed 10 years of experience as a Network Engineer in Enterprise and Service Provider settings.
Abstract:	Traditional source routing using IP header options was never widely deployed due to security concerns. Recent buzz around Segment Routing (a.k.a. SPRING) has re-invigorated interest in source routing technologies and their potential benefits. For many operators however, moving to SPRING represents a significant change in their operating practices, so in a more incremental approach they are implementing SPRING-inspired designs using current technologies with minor augmentations. In this talk we will review SPRING/SR, but will mainly focus on using existing protocols for achieving similar benefits. We will discuss: - clever usage of static LSPs to achieve predictable label values in a data-center network - minor enhancements to BGP-LU for more resilient EPE (Egress Peer Engineering) - interoperability considerations between SPRING and non-SPRING domains
