Title
Service continuations: an operating system mechanism for dynamic migration of internet service sessions
Abstract (type = abstract)
We propose service continuations (SC), an OS mechanism that supports seamless dynamic migration of Internet service sessions between cooperating multi-process servers. Service continuations provide a server application with a simple and easy to use abstraction, and a means to migrate the service state along with the serviced connection. SC supports transparent resumption of service to the client at another server, and guarantees integrity and consistency of communication channels used by server processes. SC is a generic, application independent mechanism that can be used to provide service continuity and availability for today’s complex Internet services. We have implemented SC in FreeBSD and used them successfully in three real servers: the Apache web server, the PostgreSQL transactional database server, and the Icecast streaming server. We present results of an experimental evaluation showing that using SC adds negligible run-time overhead to existing servers and that SC enable efficient dynamic migration of client sessions.
