Re: [Babel-users] ANNOUNCE: important babels update.
A new *incompatible* version of Babels is available. It is incompatible because we have changed the Source Specific Update TLV's format. Matthieu, I cannot find the Source Omitted field any longer.

Re: [Babel-users] ANNOUNCE: important babels update.
Matthieu, I cannot find the Source Omitted field any longer. Did you remove it? Yes, it's not a mistake. The Idea is that you will sort your TLVs by lexicographic (dst, src) in a Babel packet. Usually, the source prefix will not begin the same than the destination prefix cached: - external destinations are for addresses in our prefix, so in a different prefix, - destinations in our local network are probably /128 which are not source specific. In both case, we will change the source prefix. Now, consider we re-add both a flag field, and a src-prefix field, to memorize the source prefix, and consider we have 2 (or more) source prefix. Since we have sorted the message by lexicographic (dst, src), we will have, for example: (d1, s1) (d1, s2) (d2, s1) (d2, s2) and anyway, you will be obliged to rewrite the prefix. Now, if you believe it's important to rethink things and have a more memory efficient protocol, perhaps having a dictionary TLV with, as you explain me (or more precisely what I understood), with all current TLVs redefined as sub-TLVs... (probably isn't it the time for that.) Matthieu ___ Babel-users mailing list Babel-users@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/babel-users
Re: [Babel-users] ANNOUNCE: important babels update.
Suppose my network has prefixes 2001:bad:c0ff:ee::/64 and 2001:0dd:f00d:1/64. Then I'll see: 1. 64 routes towards both prefixes, typically /128; 2. default routes from both /64. If I place the source-specific after the right /128, I can compress the source prefix. so you earn 14 bytes in one packet... (?)

I haven't looked at the latest version of your code yet, but if the packet parser is not too horrible, we might want to freeze this version of the packet format. Let's discuss it on Monday. -- Juliusz ___ Babel-users mailing list Babel-users@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/babel-users
[Babel-users] ANNOUNCE: important babels update.
Dear all, A new *incompatible* version of Babels is available. It is incompatible because we have changed the Source Specific Update TLV's format. The source-sensitive branch of my public repositories has been forced-updated. All branches are rebased on the 1.5.1 version. Please update all your routers with the new version. git clone -b source-specific git://git.wifi.pps.univ-paris-diderot.fr/babels.git http://git.wifi.pps.univ-paris-diderot.fr/?p=babels.git https://github.com/boutier/babeld Note the babels openwrt's package targets my source-specific branch : your should be able to compile it directly after updating your sources. If you see Couldn't parse packet messages, it is probably that some of your routers are not updated. Have fun !

A new *incompatible* version of Babels is available. It is incompatible because we have changed the Source Specific Update TLV's format. Note that we've not frozen the packet format yet -- we reserve the right to break your routers again, just to be annoying. However, we've started documenting the protocol -- our WIP is on: http://www.pps.univ-paris-diderot.fr/~jch/software/babel/draft-boutier-babel-source-sensitive.html -- Juliusz ___ Babel-users mailing list Babel-users@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/babel-users
