Abstract: This invention provides a method of operating a controller for controlling a performance test in one or more access networks, wherein a first access network of the one or more access networks includes a first access node, a first plurality of network nodes and a first communications medium, and each network node of the first plurality of network nodes is connected to the first access node by the first communications medium such that the first communications medium is shared by the first plurality of nodes, the method comprising the steps of: obtaining data identifying the first communications medium of a first network node of the first plurality of network nodes; determining that a count of concurrent performance tests of the first communications medium is less than a first threshold; and in response to the determination, causing initiation of a first performance test of the first communications medium in which the first network node is a participant of the first performance test. This invention further provides a method of operating a network node of a first plurality of network nodes in a first access network, the first access network including a first access node and a first communications medium, and each network node of the first plurality of network nodes is connected to the first access node by the first communications medium such that the first communications medium is shared by the first plurality of nodes, the method comprising the steps of: sending a performance test request message to a controller, the performance test request message identifying the first communications medium; and receiving a performance test response message from the controller; and in response to receiving the performance test response message, participating in the first performance test.

Abstract: A communications router (6) is provided with an add-on device (7) for diverting data traffic over a replacement connection (70, 80) when a primary connection route (60) meets a failover criterion. Traffic addressed to an allocated network address associated with the primary connection (60) is diverted to a network termination of the replacement connection (70) by a routing function (31) if the replacement connection (70) has been authenticated by an authentication system (35). Authentication is provided by setting up an association between the internet IP address of the router (6) when addressed through the link (60), and a network identity of the add-in unit (7). This may achieved by having the add-on unit (7), when first installed, transmit its identity of a SIM over the fixed line connection (60) to the authentication system (35), which can then associate that SIM identity with the network address from which it has been received so that during a subsequent failover condition traffic addressed to the fixed-line network address can be diverted to the replacement connection, thereby allowing the same network address to be used during the failover condition.
