Hi, all
I'd like to introduce a socket communication facility optimized for sending
and receiving data between domains in a single machine, named Xway.
Xway is a network module that enables socket programs running on virtual
machines in a single machine to communicate each other efficiently though
socket interface. Xway shows better socket communication latency and
bandwidth than the native socket of Xen. Xway also provides binary
compatiblity for socket interface, so that the socket programs don't have to
be recompiled to exploit the advantages of Xway.
We have tested the binary compatiblity for a couple of programs such as ssh,
vsftp, proftp, apache, and mysql.
Those programs works well without any recompilication or modification to the
source codes as we expected.
The main schemes of Xway are as follows:
1) shared memory between domains
2) bypassing TCP/IP and Domain 0
3) dual channel approach dividing data send/receive and others on a socket
The implementation of Xway can be found at
http://sourceforge.net/projects/xway.
It consists of kernel patch, a kernel module, and a user daemon.
Please evaluate Xway and comments on it .
Feel free to contact me if you meet problems when installing and evaluating
it.
Thank you in advance.
