The invention provides a system and method of controlling timing of release of traffic for a communication switch. The traffic originates from at least one source, is directed to a common ingress point of the switch and is directed to a common egress point in the switch. The egress point has a maximum egress transmission rate. The traffic has at least one datastream. Each datastream has a requested transmission rate. The method comprises, for each datastream, establishing a maximum cell release rate such that a sum of each of the maximum cell release rate does not exceed the maximum egress transmission rate and utilizing the maximum cell release rate to govern release of local traffic in the datastream from the ingress point.

Methods and apparatus for the dynamic assignment of re-assembly queues to multiple connections in a communications system are described. In a preferred embodiment of the invention an ATM to MPLS mediation application is implemented. In the mediation process ATM cells are assigned to re-assembly queues where they are converted to MPLS packets for transmission over a MPLS tunnel. Typically there are many more connections than re-assembly queues which necessitates a dynamic assignment of the re-assembly queues to ensure efficient operation of the system. Re-assembly queues are serviced based on either a cell count or a timing factor.

Dynamic assignment of re-assembly queues

A method and apparatus for sending packets from traffic flows to queues in a network element is provided. Each traffic flow has a packet size parameter indicating a sizing constraint for its packets. The method includes the step of grouping the traffic flows into groups utilizing the packet size parameter of each traffic flow. The method further includes the step of sending packets only from traffic flows of one group to at least one designated queue. Traffic flows of the one group are identified utilizing the packet size parameter of each traffic flow.
