A system and method for controlling queue size in a multiprocessor environment wherein items taken from queues associated with a first processor continue to use system resources in a second processor. A three pointer system is used to distinguish between an enqueue location, a dequeue location and a virtual dequeue location. The virtual dequeue pointer is indexed only after items taken from the queues have completely cleared the system. An application of the three pointer system in a Carrier Scale Internetworking (CSI) architecture is also discussed.

Integrated management of multiple networks with different topologies

A data transmission network includes a plurality of data processing devices for connection to local data sources. The data processing devices assemble data packets from the local sources into frame relay packets. A plurality of interconnected network nodes are connected to the data processing devices. Point-to-point frame relay links (FRLs) are established between nodes of the network. Frame relay switches installed at the nodes for switch frame relay packets between successive frame relay links through the network. Frame relay paths (FRPs) are established between endpoints of the network using a plurality of successive established frame relay links.
