Dynamic throughput allocation in a converged voice/data services network interface

The present invention generally relates to the area of integrated communications network and more particularly to methods and mechanisms for controlling connections on one or more physical links supporting both fixed throughput (voice/video) and variable throughput (data) connections between an external network and a set of end nodes on an internal network. A dynamic throughput allocation method and framework are disclosed. The method includes initially providing an interface having a finite throughput. The data calls are allocated varying portions of the connection's available throughput. A throughput allocation server assigns portions of the finite throughput supported by the interface to connections between ones of a set of internal nodes and ones of a set of external nodes connected to ones of the set of internal nodes. The throughput allocation server includes a table describing the portions of the finite throughput assigned to each one of the connections. A throughput allocation controller monitors the available throughput. When under heavy usage, the throughput allocation controller determines that available throughput is less than a minimum desired value, and in response de-allocates a portion, but not all, of the throughput previously allocated to at least one data call.
