Abstract:
A method, system, and computer program product for encapsulating a packet within a virtualized network. The method includes writing one or more first translation control entries (TCEs) from a TCE table of a client system to a TCE table of a host system, and writing one or more second TCEs to the TCE table of the host system. The first TCEs indicate a location within the client system of payload data for the packet, and the second TCEs indicate a location within the host system of at least one of header and footer information to be included with the payload data.
