Unicast

Iterative TCP Unicast (that is, message is sent to each the nodes individually over TCP) can be used instead of MSMQ UDP Multicast. In addition to the improved reliability of TCP, removing the dependence of UDP Multicast simplifies deployment on cloud infrastructures. Discovering of nodes can be accomplished using the shared storage (with file locking semantics) that EFT already requires.

An advanced property must be enabled to use Unicast.

Unicast provides:

• HA support for environments that do not support MSMQ Broadcasting

• Ability for HA to work in a vMotion environment

• Improved support for node-out-of-sync detection and availability.
