Abstract

Virtual network interface selection manager in a client-server system, in which client and server are connectable through a plural alternate networks. System includes plural interfaces connectable to server through the plural networks, current interface indicator identifying a current interface through which data is transmitted to and/or received from the server, and prioritized listing of plural interfaces ranked in a descending order. Event detector detects occurrence of an event including time-out condition; successful interface test; and change in the plurality of interfaces, and a tester tests each plural interface in prioritized listing in a ranked order to test whether server is reachable. Marker identifies which of plural interfaces successfully pass the test, and switch switches from current interface to a higher priority interface when the marker identifies a higher priority interface as having successfully passed the test, whereby current interface indicator will identify the higher priority interface as current interface.
