Userspace network stack git tree is now open.
One can check it via
web interface.

New userspace network stack release.
Unetstack
is an extremely small and fast TCP/UDP/IP stack implementation on top of packet socket or
netchannels interface.
This release includes sync with the new netchannels interface,
dropped routing table support, since userspace network stack is designed on
behalf of netchannels and thus efectively single opened object operates
with single source and destination peers, so there is no need to
introduce unneded caches, since all needed information can be stored in
the userspace network stack object itself.

New userspace network stack release.
Fixed bug found by Salvatore Del Popolo (delpopolo_dit.unitn.it)
in TCP implementation, when system checked sending window and determined,
that packet was not allowed to be sent and nevertheless tried to do so in some
cases.
Userspace network stack
is a very fast (if working on top of
netchannels,
also supported packet socket) and very small network stack (TCP/UDP/IP/ethernet) implemeneted
entirely in userspace. Because of it lives near the very the end of the peer (i.e. very close
or even embedded into application), it allows much faster processing of some workloads, namely
small packet sending and receiving, where
it
outperforms
vanilla Linux TCP/IP stack 3 times in performance and 4 times CPU usage (sending and receiving vary).
Comapre netchannels+unetstack versus Linux sockets (2006 year numbers).
It is not about problems in the Linux stack, but overhead of syscalls, which are in turn
results of too separate data sending and reply processing in the existing model.
