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.

Communications path status detection system

There is a class of applications that favor expediency of the communications over reliability. Counter-intuitively, the reliability aspect of a protocol may cause sub-optimal performance when considering this special class of applications in some environments. To resolve this performance issue, the exemplary illustrative non-limiting protocol implementation favors timeliness over reliability by allowing for loss of data, thus providing a non-guaranteed, order sensitive level of service. Such features can be combined in the same system and data stream/channel with a guaranteed-reliable protocol to provide a roamable VPN simultaneously providing both guaranteed-reliable and real-time, dynamically adaptable performance.

High performance digital communications resiliency in a roamable virtual private network

A network failover apparatus and method for use in a client-server system. The method includes establishing at least a first and further path between a client and a server. The first path connects the server to the client through a first network and a first interface of the client and the further path connects the server to the client through a further network that is separate from the first network and a further interface of the client. The method also includes reaching the server through the first interface, detecting that the server is no longer reachable through the first interface, and identifying the first interface as failed. The method also includes reaching the server through the further interface after the first interface is identified as failed, testing the first interface to determine whether the server is reachable while the server is reachable through the further interface, and reestablishing a connection to the server through the first interface.
