[Openmosix-devel] Fwd:[ANNOUNCE] supporting cluster communication with TIPC

[Ian L. <Ian...@mq...>]

FYI ..

Don't have a lot of time at the moment .. but this came thru linux-net
and looked interesting ...  will read up on it later ...

> Hi all,
> I would like to announce the availability of TIPC (Transparent Inter 
> Process Communication protocol). TIPC is a protocol specially designed 
> for high-performance, location transparent communication within 
> loosely connected clusters, and has been used successfully in various 
> Ericsson products over the last years. 
> 
> In cooperation with colleagues from OSDL and Intel, I have ported TIPC 
> to Linux,and  rewritten large parts of the code to fit the Linux kernel 
> environment and coding requirements. TIPC can be compiled either as a 
> part of the kernel or as a loadable module, and is now released as 
> open source code under a dual GPL/BSD license. 
> 
> 
> Overview
> --------
> TIPC provides a good support for designing scalable, distributed, 
> site independent, highly available, and high-performance applications.
> 
> It provides features such as:
> 
> o Reliable and unreliable connectionless communication modes: 
>   SOCK_RDM and SOCK_DGRAM.
> o Reliable connection oriented communication modes: SOCK_SEQPACKET
>   and SOCK_STREAM.
> o Reliable and unreliable multicast covering the whole cluster.
> o 35-80% better performance than TCP/IP for messages < 1.5 kbytes.
>   (The tipc-1.2 line).
> o A functional addressing scheme that allows primary/secondary key
>   addressing and group addressing.
> o Ability to adapt to and be carried over different media/protocols, 
>   depending on the available network infrastructure and security needs: 
>   raw Ethernet, RapidIO, ATM/AAL5, TCP, SCTP, UDP etc.(Only Ethernet 
>   supported in the latest version).
> o A topology service helping applications to keep track of available 
>   functional and physical addresses in the clusters.

> Implementation Status:
> ----------------------
> 
> There exists two main source code lines:
> 
> 
> tipc-1.2.X: this is the most stable and tested release. It works well
>             on both Linux 2.4 and Linux 2.6. This code is not compliant 
>             with Linux kernel code requirements regarding code style etc,
>             and now only has interest for comparative reasons. The 
>             corresponding CVS modules are "source/stable_ericsson" and 
>             "source/unstable_ericsson". 
>             A downloadable example using the API of this version is found
>             under "tipc-test", the file "tipc-benchmark-0.93.tar.gz"
> 
> tipc-1.3.X: the most recent code, written for Linux 2.6, and compliant with 
>             requirements on such code. It works well, but is still slightly 
>             less stable than the 1.2 line. The corresponding CVS module is 
>             "source/unstable", while we have not had the guts to check in
>             anything under "source/stable" yet. We have not been able to 
>             verify that this code has the same performance as the 1.2 code, 
>             but we have every reason to believe it will be comparable once 
>             the proper optimization work is done.
>             A downloadable example using the API of this version is found
>             under "tipc-test", the file "tipc_test-1.5.tar.gz"
