Abstract
A method for cache coherency in a network of a plurality of caching agents includes storing a plurality of miss requests, transmitting the miss requests into the network, sending a probe message on a probe channel and a request message on a second channel from one of the plurality of caching agents, and maintaining an open status for the miss request until the requesting cache agent receives the data or an ownership indicator.
