  • Mapping of high bandwidth connections in a multi-stage switch
    Patent number: 6816487
    Abstract: A high bandwidth connection is mapped through a multi-stage switch between an ingress node and an egress node via a center stage comprising M (an integer) center stage nodes. Each center stage node is connected to the ingress and egress nodes by respective links adapted to support m (an integer) respective connections. An m×M connection matrix of connections between the ingress node and the center stage is provided. Each column of the connection matrix contains 1≦j≦m connections between the ingress node and a respective one of the center stage nodes, and each row of the connection matrix contains 1≦k≦M connections between the ingress node and the center stage nodes. The high bandwidth connection is mapped through the multi-stage switch by layering the high bandwidth connection within the connection matrix. Thus the high bandwidth connection is divided into N segments.
