Abstract: Method and apparatus for providing integrated network and operations control for a converged communications network providing all service types on a common architecture.

Abstract: A method and apparatus for providing a centralized or regionalized transcoding function are disclosed. For example, the method detects a codec mismatch during a call setup between a calling party endpoint device and a called party endpoint device. The method then invokes a transcoding function directly by at least one border element (BE) to handle the detected mismatch, where the transcoding function is performed by at least one centralized or regionalized transcoding server and at least one media resource.

Abstract: In order to provide a single common cost-efficient architecture for real time communication services for audio, video, and data over internet protocol, a voice over internet protocol (VoIP) system and architecture is provided by placing border elements (BEs) at the interface boundaries between the access network the user devices use and the VoIP infrastructure. The BEs use SIP protocol as the access call control protocol over any access networking technologies, for example, IP, Ethernet, ATM, and FR, and provides all services transparently to the end users that use SIP-enabled devices. To enable a scalable system, the SIP BEs are decomposed into separate communicating entities that make the SIP BE scalable and provide new capabilities not previously available by a self-contained SIP BE.

Abstract: A method and system for providing fairness of capacity allocation in a network is presented. The method includes intercepting RSVP messages at a PE router, counting capacity requests for reservable classes of service for each VPN on each LSP, and rejecting requests when a VPN has inadequate capacity on the specific LSP. The present method allocates capacity to MPLS VPNs fairly, so that none is starved by the greediness of other VPNs sharing the same LSP.

Abstract: In a time division multiple access communication system utilizing a satellite for communicating signals between a plurality of ground stations, at spaced times a reference ground station reallocates the total channel capacity of the system among the several ground stations to minimize system blocking and to thereby utilize the available system channel capacity more effectively. To increase the time between successive reallocations, channels are reallocated only when a ground station makes a channel capacity request that is greater than or equal to its corresponding present channel allocation. System blocking is minimized by using a table look-up scheme to generate excess capacity allocation factors for the stations and to thereby determine each station's proportionate share of excess system capacity. An appropriate portion of excess capacity is then added to each station's channel capacity request to provide a new channel allocation for each station.
