What is the function of T3 in WebLogic Server? (EJB)

Question :What is the function of T3 in WebLogic Server? (EJB)
Answer :T3 provides a framework for WebLogic Server messages that support for
enhancements. These enhancements include abbreviations and features,
such as object replacement, that work in the context of WebLogic Server
clusters and HTTP and other product tunneling.
T3 predates Java Object Serialization and RMI, while closely tracking and
leveraging these specifications. T3 is a superset of Java Object.
Serialization or RMI; anything you can do in Java Object Serialization and
RMI can be done over T3.
T3 is mandated between WebLogic Servers and between programmatic
clients and a WebLogic Server cluster. HTTP and IIOP are optional
protocols that can be used to communicate between other processes and
WebLogic Server. It depends on what you want to do. For example, when
you want to communicate between
n A browser and WebLogic Server-use HTTP
n An ORB and WebLogic Server-IIOP.
