NANOG Meeting Presentation Abstract

Supporting Jumbo Packets on the Internet
Meeting:	NANOG42
Date / Time:	2008-02-19 3:00pm - 3:30pm
Room:	Imperial Ballroom
Presenters:	Speakers: Tom Scholl, AT&T Labs Tom Scholl is a Lead New Technology Product Development Engineer at AT&T Labs. In the Global IP/MPLS backbone design & development team, he works on the design of routing architectures for the core network. Additional tasks include 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 network engineering roles.
Abstract:	With modern Ethernet equipment supporting frame sizes well above 1500 bytes, operators do not typically always agree upon an interface MTU between each other. To complicate this, vendors configuration commands also confuse operators as well. Inconsistent MTU settings can result in negative behavior for any network. This presentation covers the problems of inconsistent MTU settings, no MTU negotiation capability and other issues when operating at Internet exchange LANs.
