PQ 152: An IETF Update On RIFT, BIER, SD-WAN And More

Today, an update on some compelling projects at IETF 102. Ours guest are Jeff Tantsura and Russ White. We review the following projects to see what’s new and understand what problems they’re solving: * RIFT (Routing In Fat Trees) * BIER (Bit Indexed Explicit Replication) * PPR (Preferred Path Routing) * YANG data modeling We also look at the state of SD-WAN, which is a bit of the Wild West, to look at standards and interoperability efforts underway. Jeff is the Head of Technology Strategy at Nuage Networks. He’s also deeply involved with the IETF as the Chair of Routing Area Working Group, the Chair of Routing In Fat Trees, a Member of Internet Architecture Board, and a Member of IP Stack Evolution. Jeff has recorded with us several times before, most recently on Priority Queue 126, where Greg chatted with Jeff about the future of data center fabrics. Jeff, welcome back to Packet Pushers. Russ White is a network architect, author, and blogger. Rush also chairs the Interface to Routing System and the Babel routing protocol efforts at the IETF, and is a reviewer in the IETF’s Routing Area Directorate.
