Abstract:
An asynchronous transfer mode (ATM) switch for a telecommunications node, comprising:switch memory including a plurality of discrete queues; an ingress queue a first dedicated to a first connection from which a first traffic stream is received in cells in an inverse multiplex ATM (IMA) format; an second queue dedicated to a second connection over which a second traffic stream is transmitted in cells in an IMA format; and a switch controller operable to receive a plurality of cells, to identify cells for the first connection, to reconstitute and queue cells for the first connection in the first queue based on order information received with the cells, to switch the first traffic stream, to store-cells for the second connection in the second queue, to extract cells from the second queue in an order of transmission, to overwrite an upper portion of a virtual path indicator (VPI) in each successive cell for the second connection with order information that comprises a count value, and to transmit the cells from the second queue with the order information over multiple links to a destination node.
