[PHANI] The name-transparency and subscriptions were features that proved to be very useful. More so because they come bundled along with the same transport medium that understands those names etc. > Were there things missing? Things that should have been done > differently? [PHANI] The following things come to my mind: - A recent suggestion by Randy McLeod (mail titled "tipc and routing"). It could be useful to be able to instruct TIPC to use a specific link for certain kind of traffic. - Perhaps a "pure-connectionless" mode of TIPC traffic may be useful. The connection-less mode that TIPC supports right now still seems to undergo a "connection-like" treatment at inter-node level. That can introduce latency and unnecessary retransmissions. Additionally, send-operations could get blocked (for a max. of link-tolerance duration) if blocking sockets are used or we end up getting EAGAIN more often than actually required. A "pure-connectionless" mode could help in providing a "best-effort" service with "low-latency". > Have you identified missing features that would make it > suitable for use > in other services?

TIPC has primarily been used to fit into Opensaf's MDS requirements and therefore, I would say, TIPC is not fully utilized by MDS yet. Things such as TIPC's multicast feature are yet to be explored by Opensaf. > > Regards > ///jon > > Marella P-G19460 wrote: > > Hello all, > > > > TIPC group may be delighted to know of another software suite that > > uses the TIPC protocol - OpenSAF. > > > > OpenSAF is an open source implementation of a high availability > > operating environment which includes an implementation of > the SA Forum > > Application Interface Specification (AIS).
