A system and method can implement highly available Internet Protocol (IP) based communication across multiple independent communication paths. The system can have different IP addresses associated with different interfaces and communication paths and can implement communication fail-over as part of the communication layers above the IP layer, e.g. at the application level. The system can provide a balance between an average fail-over time and implementation complexity, and can achieve simplicity and robustness while providing high communication performance.

System and method for supporting high available (HA) network communication in a middleware machine environment

A system and method can ensure Internet Protocol (IP) address and node name consistency when performing remote transactions via multiple un-related IP addresses for the same remote peer. The system can ensure that all cooperating peer nodes are in full agreement of the names and IP addresses at any point in time. In particular, when network configurations can be updated dynamically, the system can ensure that such updates do not lead to inconsistent or failed transactions because a peer node has a stale view of what addresses to use. Furthermore, the peer node that initiates the transaction can verify that all the other peer nodes have exactly the same view of the overall system configuration, in order to ensure that each distributed transaction is carried out using consistent address information.
