  1. draft-touch-trill-prob-00 Joe Touch Postel Center Director Research Assoc. Prof. CS & EE USC/ISI

  2. Current Status • Redistributed author load • Touch – Problem & Applicability Statement • Gray – Architecture • Perlman – Protocol • Issues list • Posted lists • Discussion on issues • New drafts • Arch • Protocol

  3. Issues 1-3 (of 16) • #1 which version of ethernet is baseline? • STP, RSTP, VLAN, provider bridges, wireless, shortest path bridging, etc. (terminology issue) • #2 apply to current vs. larger scales? • Proposed starting point: • 1000 end-hosts in a single bridged LAN of 100 bridges • 100.000 end-hosts inside 1000 VLANs served by 10.000 bridges • #3 IF size is an issue... • what limits the size? STP/RSTP or broadcast traffic, or both?

  4. Issues 4-7 • #4 delivery requirements: • a) is in-order required? • b) is no-duplication required? • #6 address MSTP regions (esp sec 2.2) • as a way to limit STP scale/reconfiguration • IEEE 802.1Q Multiple Spanning Tree Protocol? • #7 differentiate between host reattachment effects • and bridge reattachment effects; the latter impact the STP more

  5. Issues 8-10 • #8 broadcast vs. subnet bcast vs. mcast • who gets a copy of multicast? all ports, or just subscribed? • #9 which addresses are not forwarded? • Bridge Group Addr 01-80-C2-00-00-00 (BPDU frames) • Pause Frame address 01-80-C2-00-00-01 • ?addresses 01-80-C2-00-00-00 to 01-80-C2-00-00-0F • #10 use campus (agreement at last meeting?) • or use "pool" or "set"

  6. Issues 11-13 • #11 internal/external, inside/outside terminology • CLOSED - moved to ARCH issues 12/08/2005 • #12 address VLAN configuration requirements • See recent discussion on mailing list. • #13 need configuration time examples • e.g. references to published research and a summary that shows how small changes can have large effects

  7. Issues 14-16 • #14 add risks of TRANSPARENT • (larger trees, slower to converge, etc.) • #15 sec 2.3 should be more clear about referring to computing backups to • use in case of failure - not that extra links makes routing easier. • #16 clarify ARP replay vs. proxu ARP • (a desired performance optimization) • (agreed on the mailing list)

  8. Next Steps • Approve as WG document • Revise • to unify terminology • to address issues • Restart issues resolution
