Abstract
In a packet telecommunications environment, a method is provided for end to end explicit rate control through a plurality of heterogeneous internetworked networking topologies comprising networks without explicit rate signaling, such as TCP/IP based LAN subnets, and networks with explicit network layer rate signaling, such as Frame Relay permanent or switched virtual circuits (PVC/SVC) or ATM available bit rate (ABR) services by reallocating bandwidth in a partition using a Committed Information Rate of the portion comprising the virtual circuits for a partition size. In specific embodiments, the invention may exist as an integrated device, such as an enhanced FRAD, or a bandwidth management device, which detects congested network conditions from information obtained indirectly from a FRAD or network edge device using techniques such as reading the network edge device's MIB.
