Abstract: In one illustrative example, a mobile network extender has a network interface configured to connect with a host router and a cellular modem configured to provide a wireless link for communications via a cellular mobile network. In a pairing process, the extender may establish a secure encrypted channel with the router via the network interface. In a locking process, the extender may receive information from the router and verify the information. Upon verification, the extender may be set in a locked state in which the extender is logically locked to the router. The extender may also receive and store a secret session key from the router, and permit the router to acquire the extender for communications. In the locked state, the extender may permit or deny subsequent router acquisition upon router reconnection based on verifying, using the secret session key, authentication data received via the network interface.

Abstract: A system, method and computer program to detect and recover from a communications failure in a computer network. The computer network has several nodes which include processor-based systems, input/output controllers and network controllers. Each node has a cluster adapter connected to multiple port switches through communications links. Data is transmitted through among the nodes through the communications links in the form of packets. A fabric manager module will monitor the network and detect a link failure. Upon the detection of a link failure between two switches a spanning tree partitioning module will partition the network into two trees at the point of the link failure. Thereafter, a link and switch identification module will identify a link between the two trees that can replace the failed link and has the least impact on the network. A routing table calculation algorithm module will calculate a new routing and distance table based on the identified link.
