Abstract
Network servers in a cluster share the same network protocol address for incoming client requests, and in a data link layer protocol a reply of a client to a request from a server is returned to this same server. For example: (1) ports of the servers are clustered into one single network channel used for incoming and outgoing requests to and from the servers; or (2) ports of the servers are clustered into one single network channel used for incoming requests to the servers and a separate port of each of the servers is used for outgoing requests from each of the servers; or (3) logical ports of the servers are clustered into one network channel used for requests to the servers and a separate logical port of each of the servers is used for outgoing requests from each of the servers.
