IETF 76 6lowpan WG Minutes Monday November 10 2009 1300-1500 ---------- Agenda: Introduction - Chairs Routing Requirements - Chairs Use cases - Chairs HC - Chairs/Jonathan Hui Security - Chairs/Ki-Hyung Kim MIB - Ki-Hyung Kim SNMP Opt - Hamid Mukhtar ND - Zach Shelby 6LowApp Pointer, New Work? - Chairs ---------- Meeting Discussion: -- Introduction Carsten provided an introduction to 6lowpan and the agenda -- Routing Requirements After a short discussion and a review of the mailing list traffic Geoff and the working group decided that the Routing Requirements document was complete. Geoff will prepare it for the IESG. -- Use Case Document As there were some recent changes to the Use Case draft and some recent comments the group decided that there would be one more revision and then we would do a WGLC. -- Header Compression Draft Jonathan Hui give a quick status update for the HC draft. After a short discussion the WG felt the the draft is ready for WGLC. Geoff will issue a WGLC. -- Security Ki-Hyung Kim gave a presentation on the Security Analysis draft. The draft is an informational draft. Last updated by Wasim Haddad of Ericsson July 2009. Part of the point of the draft is to understand that many security mechanisms that could be used on standard IP devices are problematic for 6lowpan devices due to memory, processors and power. The question was asked if the document was ready to become of WG doc. Most people appeared to have not read the document. There was no consensus. We need to take this to the list. -- 6Lowpan MIB Ki-Hyung Kim made a presentation about 6lowpan MIBs. Ideas included: generic parameters: device roles device capabilities routing protocol route over parameters mesh under parameters statistics -- SNMP Optimization Hamid Mukhtar presented information about using SNMP in lowpans. This is a follow on to his presentation at the last IETF. New version of draft focuses on SNMPv3 applicability. Presentation covered: Contexts, Proxies, and use of snmp on lowpans. While SNMP would fit in 15.4 frames it would still use min of 67 bytes for snmpv3 and 20 bytes for snmpv1 for just the headers, leaving little space for snmp data. -- 6lowpan ND draft Zach Shelby presented information about the latest draft 07. There have been a number of small changes to the draft since the last IETF and draft 04. The discussion during the presentation was focused on the base requirements that lead up to the draft. One of the main topics of the requirements was and the necessity of DAD. If DAD is not required then the requirements for white boards and such maybe in question. The WG felt that DAD was not a requirement and requested that the authors take the draft and split it into two pieces. The first draft should focus on the most base functionality necessary for ND to work over 6lowpans, both for mesh under and route over networks and it must be compatible with RFC4861 and avoid single points of failure.
