SAVI for Mixed Address Assignment Methods Scenario 
draft-bi-savi-mix-04.txt  
Eric Levy-Abegnoli

Eric Levy-Abegnoli presented SAVI for Mixed Address Assignment Scenario (draft-bi-savi-mix-04).
Eric first introduced the major changes since -03 version: text cleanup to reflect the outcome during ieft79 meeting to make the draft simpler and compliant with RFCs. The mixed environment is a potential risk in real deployment, so Eric introduced the way to avoid conflict and the way to handle conflict. 
Marcelo Bagnulo: The case of SEND/Non-SEND collision is in low possibility, but I hope the attacking case can be documented in the draft.

Eric then introduces a new proposed mechanism to allow the SAVI device to defend the DHCP address pool.
Marcelo: How does the SAVI device know the unused DHCP addresses?
Eric, and Joel Halper: one way is configured by administrator, another way is to have the SAVI device snooping DHCP messages.

Eric finished the presentation after introducing some other contents including handling conflict in binding removal, multiple switches scenario, etc. Then Eric asked, as this is already the -04 version and the WG agreed a mixed draft is needed, if the current version could be adopted as a WG draft. The WG chair asked the audience, about 5-6 people said it can be adopted as WG draft, nobody said it not acceptable. The chair agrees to include it as a WG draft and will ask for confirmation on the mailing list.

CNGI-CERNET2 deployment update
Jun Bi

Jun Bi presented CNGI-CERNET2 SAVI deployment update. Jun first reported the latest SAVI deployment progress in CERNET2, where 100 universities campus networks had deployed SAVI switches and the confirmed SAVI users are now around 900K. Then Jun introduced a new work which is SAVI for WLAN (draft-bi-savi-wlan-00). There are some new challenges in wireless environment and Jun introduced how it was handled. In the last part, Jun introduced the SAVI MIB design (draft-an-savi-mib-00) and a SAVI network management system.

WG roadmap: next steps
Jean-Michel Combes

Finally, Jean-Michel led the WG to discuss the next steps for SAVI WG.
Jean-Michel reviewed the current charter and introduced the next steps of current WG drafts.

Joel: For those draft that had ever been asked WGLC, if there is only minor changes, it doesn't need WGLC again.
Jun Bi: The WGLC for savi-dhcp had been completed after ietf79 and the -07 version with minor text changes had been finished two months ago. Since there are no more comments, it is suggested to go to IESG directly.
Jean-Michel: will think about those suggestions. 

The conclusion is to move forward to IESG review all the SAVI WG documents before the next IETF meeting in Quebec, then discuss in SAVI mailing-list about new items for a potential rechartering during the next IETF meeting.
