Dear all, I've finally gotten my act together, and finished implementing the new AHCP protocol. You will find it on
http://www.pps.jussieu.fr/~jch/software/files/ahcpd-0.50.tar.gz http://www.pps.jussieu.fr/~jch/software/files/ahcpd-0.50.tar.gz.asc You will find a somewhat incomplete description of the protocol on the AHCP page, http://www.pps.jussieu.fr/~jch/software/ahcp/ The new protocol has a number of advantages over the old one. First of all, it is much simpler -- just 5 states for the client, as opposed to 8 for the old protocol, and no layering violations. Additionally, it is completely routing-agnostic: it will work fine in a Babel network, an OLSR network, a BATMAN network, or even a network with no routing protocol at all. The main downside is that there is no stateless component in the new protocol: when the network partitions, the part that is partitioned away From all the AHCP servers will only survive for the time it has a lease; in the old protocol, IPv4 would die, but IPv6 would survive almost indefinitely. The implementation is not quite finished; in particular, it doesn't do server selection right. This means that it will work fine if there's only one AHCP server in the network, or if all servers are equivalent; it will do stupid things when e.g. some servers serve both IPv4 and IPv6 addresses, but others do IPv6 only. So don't do that. Enjoy, Juliusz
