  • Patent number: 8644150
    Abstract: A method and system for performing admission control in a packet-based telecommunication network includes a backbone network coupled between at least two access networks. When a first user on a first access network wants to communicate with a second user located on a different access network, a request is made to a quality server whether network resources are available. The quality server separately monitors both access networks and the backbone network and determines whether network resources are available to satisfy the request. In one embodiment, a two-tier approach is used wherein a coordinator module interacts with an admission control subsystem including a plurality of subsystem modules. Each admission control subsystem module is responsible for monitoring a part of the network, such as, one access network or a backbone network. The coordinator module determines which subsystem modules are associated with the user request and interrogates such subsystem modules as to resource availability.

  • Patent number: 7801152
    Abstract: A system for scheduling utilization of a service resource by a plurality of flows of information packets, wherein the flows include rate-guaranteed synchronous flows and best-effort asynchronous flows, the asynchronous flows exploiting the service capacity of the resource left unexploited by the synchronous flows. A server visits the flows, in subsequent rounds, by visiting first the synchronous flows followed by the asynchronous flows. The server is configured for detecting any backlogged synchronous flow, and when the server visits any said backlogged synchronous flow, it allows the backlogged synchronous flow to utilize the resource for a given time, whereby the synchronous flows have a guaranteed transmission window on each round. When the server visits any asynchronous flow, the time elapsed since the last visit by the server to the same asynchronous flow is determined.
