摘要： A method and apparatus to control call admission to a packet-based network and achieve load balancing over a packet-based network includes at selected times generating and sending a path status message along a defined path, such as an MPLS path, through the network. As the message travels along the path, a cost metric field within the message is updated. The cost metric may reflect available bandwidth, or percentage utilization of the aggregate bandwidth, on the most congested (bottleneck) link in the path that it tracks. The cost metric is determined for each link at a data measuring point, such as individual routers, along the path. The optimum path between two gateways is determined, and further packet streams are routed onto the optimum path. In the event that no paths between a source and destination gateway meet predetermined utilization criteria, a packet stream block indicator is set which shows a requesting edge router that no paths are currently available for a packet stream requesting routing between particular source and destination gateway. The path utilization status message may be generated alternately in routers or in a master gateway. In either case, the messages are sent and the status of the network is determined in a distributed fashion at selected times, such as a regular timed interval.

摘要： An admission control and load balancing system controls admission of packet streams or calls to a network and balances the packet traffic across the network, improving quality of service. The system includes a central database which stores information including cost data associated with individual paths and links across the network. A processor, in communication with the database, coordinates the admission control and load balancing decisions, and updates of the database cost data to reflect the dynamic network conditions, based on input from appropriate data sources. In one embodiment, referred to as the exact algorithm, the database is consulted by the admission control points or gatekeepers prior to admitting each arriving packet stream, and the database contents are updated call-by-call to reflect the allocation of resources to each admitted stream. In another embodiment, referred to as the inexact algorithm, control decision as well as database updates occur on a periodic rather than on a call-by-call basis to promote better scalability. In this embodiment, the processor periodically calculates admission decisions based on cost data in the central database. These admission decisions are then periodically forwarded to a satellite database associated with each gatekeeper, for storage and use in admission decisions until the next update epoch.
