TLDR
In this paper, the authors propose a hybrid network including a nonguaranteed quality of service packet switched local area network and a circuit switched ISDN wide area network having a centralized multimedia bridge located within the wide-area network.Abstract:
Real-time multimedia services are transmitted over a hybrid network including a nonguaranteed quality of service packet switched local area network and a circuit switched ISDN wide area network having a centralized multimedia bridge located within the wide area network. The local area networks and multimedia bridge are interconnected via ISDN routers. An algorithm executed by the multimedia bridge receives signals from the packet switched network and detects the absence of properties needed for real-time audio visual services. The data signals are processed to compensate for the absence of the properties and then are transmitted over the wide area network to enable real-time audio visual services.read more

Sigmund Gavish,Roni Even +1 more
TL;DR: In this article, a multimedia gateway for use in a multipoint communication system is described that incorporates an interactive voice response unit through which users of non-Internet protocol devices (connected to the multimedia gateway) interact to establish a communication session with a multi-hop communication system.
Patent
Mechanism to guarantee quality of service to real-time traffic on IP networks
TL;DR: In this article, a system for routing of data traffic on a communications network comprising a plurality of gatekeepers interlinked to form a network wherein the plurality of routers aggregate real-time flow of data packets through said gatekeepers, and terminals which are connected to the network via the gatekeepers negotiate connection parameters.
