SAVA Update and Refocus SAVA Framework Updated – now just three levels First Hop SAVA – how to gain trust in SRC Address. Intra-AS/Domain SAVA – How to preserve trust level from one edge of a domain to the other. Inter-AS/Domain SAVA – how to communicate and preserve trust level between admin domains. 2 Levels of trust of SRC address defined: “Strict SAVA” – host-level granularity. “Loose SAVA” – address-range/prefix level granularity. SAVA work is initially being focused on the First Hop. Will need to develop solutions for each access case. Local subnet in Enterprise networks Residential broadband, wireless mobile, etc. Focus for rest of 2007 is work towards BoF in Vancouver Charter to complete the work on local subnet/first hop and the framework doc. |
