Source-specific routing ======================= We've found a problem with interoperability between source-specific Babel and plain Babel. I don't think the current implementation has the problem, but the current packet format does in principle allow encodings that plain Babel will mis-parse. Rather than setting complex rules that work around the problem, we're planning an incompatible change to the format of source-specific updates. Dave is not pleased. http://mid.gmane.org/E54827C6-2083-49D2-AB79-FF75BE72177D@pps.univ-paris-diderot.fr http://mid.gmane.org/87lhsdysis.wl%25jch@pps.univ-paris-diderot.fr Extension mechanism =================== We're working on formalising the extensions mechanism: http://datatracker.ietf.org/doc/draft-chroboczek-babel-extension-mechanism/ http://tools.ietf.org/html/draft-chroboczek-babel-extension-mechanism The current -01 doesn't specify a policy for TLV and sub-TLV assignments, we're planning on "Specification Required" together with a range of 16 codepoints reserved for experimentation. If you have strong opinions on the subject, please let us know now rather than later. http://mid.gmane.org/8761jgvt3s.wl%25jch@pps.univ-paris-diderot.fr http://mid.gmane.org/CAGnRvuq_PJe1wrcZqaUqwsqpoUH3A4HTcSSsFhQ=H+SLjfaQzg@mail.gmail.com Other drafts ============ In other news, the authentication draft is in AUTH48 (yay!): http://datatracker.ietf.org/doc/draft-ovsienko-babel-hmac-authentication/ http://tools.ietf.org/html/draft-ovsienko-babel-hmac-authentication there's a first cut at the RTT-based routing (overlay networks) extensions: http://datatracker.ietf.org/doc/draft-jonglez-babel-rtt-extension/ and a very early draft of the radio diversity extensions: http://www.pps.univ-paris-diderot.fr/~jch/software/babel/draft-chroboczek-babel-diversity-routing.html There's still no complete description of the source-specific routing extensions. -- Juliusz
