The invention relates to a computer system and method for high availability processing through a session on a transport connection, for use in a cluster with at least two nodes. The system comprises a protocol component; a cluster with at least two nodes, said cluster being arranged for running the protocol component; and a server arranged for maintaining a protocol session on a transport connection with a node of the cluster. The cluster is arranged for maintaining on each of said at least two nodes one instance of the protocol component, so that at least two instances are active; the server is arranged for simultaneously maintaining a protocol session with each instance.

System and method for an improved high availability component implementation

An extractor extracts from the payload of the Layer 2 packet a destination Layer 3 address of the Layer 3 packet. A forwarding engine, for in response to the extraction, with the destination Layer 3 address retrieves from a forwarding database an associated interface. The forwarding database includes at least one association between one of the plurality of interfaces and at least one Layer 3 address. Upon reception of the destination Layer 3 address having a full match with one of the Layer 3 addresses, the forwarding database provides the interface which is associated to the Layer 3 address. The network unit forwards the Layer 2 packet to the provided associated interface.
