Abstract
A boundary node for interworking between a first network and a second network comprises first equipment for interfacing with the first network and second equipment for interfacing with the second network. The first equipment comprises a switch fabric. A first interworking interface and a second interworking interface are provided for carrying traffic between the second equipment and the first equipment. Each of the interworking interfaces is for interfacing with a respective traffic-carrying path of the second network. For traffic flow in a direction from the second network to the first network, a method comprises determining that recovery switching is required for traffic on one of the traffic-carrying paths of the second network and performs a recovery switch, using the switch fabric in the first equipment, to switch between the interworking interfaces to achieve a recovery switch between the traffic-carrying paths of the second network.
