[Xen-devel] XenSocket

[Suzanne McIntosh <skranjac@xxxxxxxxxx>]

At the recent Xen Summit held in April
2007, we introduced XenSocket - a reliable, very high 
throughput, interdomain transport mechanism.


Our XenSocket solution is comprised
of a sockets-based interface to a shared-memory-based 
transport, with the goal being to significantly
improve throughput over that obtained when using 
TCP/IP for same system interdomain communication.


We have had several requests for more
detailed information about XenSocket, and also for 
access to the source code.

We have documented the XenSocket design
and performance results in an IBM technical report, 
RC24247, which can be downloaded from:
http://domino.research.ibm.com/library/cyberdig.nsf/1e4115aea78b6e7c85256b360066f0d4/0f652cbf9ea1b2ee852572ce0060baba?OpenDocument

We are planning to make the source code
available once we have ported to Xen 3.0.5, and 
completed a few features that have been
requested. We also saw the note about XWay today, 
and Ian's response. We agree with Ian
that having an interdomain byte stream protocol available 
in Xen would be of great benefit to
the community and hope our work on XenSocket and the work 
by the XWay team could make that happen.


We welcome your feedback and questions.
