You're still failing to explain why the kernel needs to do this
rather than some -lkademlia in userspace.

HTTP if more of an access protocol,the logical network is woven in
the web page controled by html, the network needed is formed and take
part in by tcp/ip protocol which usually lies in kernel.

Kademlia itself has the responsibility to weave the p2p network and
bring a node into the p2p network before access can be done.

Sorry, but no. You're suggesting adding a protocol to the kernel that
fits better in userspace without actually coming up with any reasons
why having it in-kernel would be better. Not to mention that adding
yet another protocol to the kernel means more vectors for possible
exploits.

Specifically, the reasons a network protocol goes in the kernel is
either because it needs a multiplex that isn't possible in userspace
(UDP, for example, needs a port number multiplex), or because acceptable
performance isn't possible in userspace (this mostly applies to NFS.)
