Process
migration is the act of transferring a process between two
machines during the execution of that process. Although it
has not achieved widespread use, with the growth of distributed
computing, socket migration is gaining importance.
This
project identifies the shortcoming of current process migration
approaches: the lack of network socket migration support at
the operating system level. A network socket is the interface
provided by the OS to a user program that abstracts-away the
complexities involved in network communications. A socket
is represented in a process by a socket descriptor. Comprehensive
process migration systems should include this socket descriptor
as part of the proecess that migrates. Otherwise, the candidates
for process migration are limited to processes that do not
have network connections.
MIGSOCK
is a solution to the problem of socket migration. MIGSOCK
provides a Linux kernel module that re-implements TCP to make
migration possible.
