Method and apparatus to provide centralized call admission control and load balancing for a voice-over-IP network

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.

Multiple criteria based load balancing

This invention provides the ability to load balance calls in a communications network using a certain criterion, such as a user-specified call priority, or the call service category. The method is applied when selecting a route for a new call or for re-balancing the calls across a network. When the user-specified call priority is used, the aggregated number of calls with the same priority or service category is calculated for all possible routes the new call may use. The aggregated number of calls is then divided by the number of hops in the respective routes; the route with the smallest ratio is selected for the new call. Re-balancing is performed by re-routing the calls in such a way as to obtain a similar number of calls of the same priority, or service category along all possible routes.

Active idle communication system

To reduce power consumption and heat generation, an active idle system is proposed that monitors for an idle period and then, after a predetermined time, initiates a silent period. During the silent period data and idle frames are not transmitted. During the silent period, one or more transceiver components may be turned off or forced into some other power saving mode. The predetermined time may be any amount of time and is selected to balance network usage and power savings. Periodically during the silent period, such as at predetermined times, one or more sync or idle frames are transmitted. Received sync or idle frames are processed to maintain receiver settings, synchronization or equalizer adaptation.
