Abstract
A method implemented in a computer network supports a number of client-server sessions from a protocol stack having a single physical adapter associated therewith. The method begins by associating at least two logical adapters to the physical adapter, with each of the logical adapters being adapted to handle a predetermined subset of the number of sessions. Sessions are then allocated to the logical adapters in a sequential manner. In particular, the sessions are allocated to a first logical adapter until the predetermined subset of the number of sessions for that adapter is reached, whereupon the sessions are allocated to a second logical adapter. Each session is associated with a pair comprising an identifier for the logical adapter and an entry in an associated table, with the table entry being a socket number. Communications are 'routed ' through the physical adapter and the logical adapters by associating socket numbers with logical adapter/session number pairs.
