Abstract
A messaging protocol that facilitates a distributed cache coherency conflict resolution in a multi-node system that resolves conflicts at a home node. The protocol may perform a method including supporting at least three protocol classes for the messaging protocol, via at least three virtual channels provided by a link layer of a network fabric coupled to the caching agents, wherein the virtual channels include a first virtual channel to support a probe message class, a second virtual channel to support an acknowledgment message class, and a third virtual channel to support a response message class.
