Shared Memory Communications – Direct Memory Access (SMC-D) capability was added to Communication Server 2.2 via PTF. This capability eliminates the TCP/IP processing in the data path by using shared memory instead of a wired connection. This can result in faster connection and better efficiency for system to system communications.
Today MainView for IP is making available full support for SMC-D including packet trace, and data associated with connections, ports and configurations. For more information, please follow this link.
