US Patent 7590706 Method for communicating in a computing system

One aspect of the invention is a method for communicating in a computing system. An example of the method includes establishing a local communications interface at a local site. This example also includes writing local site communication information to the local communications interface, which comprises storing the local site communication information on a first site storage device at the local site, and sending the local site communication information from the first site storage device, to a third site storage device at a remote site, wherein the local site communication information is sent using a remote data replication protocol. The remote site communications interface may read the local site communication information from a third site storage device, and may send the local site communication information to a remote application at the remote site. Similarly, the remote application may send information to a local application at the local site.
