Sessions for the TIBCO Rendezvous Transport Type

Reliable (RV)

Reliable Message Delivery ensures that each multicast or broadcast message is received as long as the physical network and packet receivers are working. It also ensures that the loss of a message is detected.

Reliable Message Delivery can compensate for brief network failures, because it can retransmit a message on request if the first attempt fails. This option is appropriate when message delivery is expected but some loss can be tolerated.

Certified (RVCM)

Certified Message Delivery ensures that every certified message reaches its intended receiver in an order. A message can be sent across network boundaries. If a network fails, delivery attempts continue until delivery succeeds or until the time limit of the message expires. This is often called guaranteed delivery.

Distributed Queue (RVCMQ)

This type of session is supported only for Subscription Service and Request-Response Service. Distributed Queue delivers a message to one of many service listeners (workers). Distributed Queue contains features of both Certified Messaging and Fault Tolerance.
