Methods, Systems, and Apparatus of Providing QoS and Scalability in the Deployment of Real-Time Traffic Services in Packet-based Networks

摘要

Methods, Systems, and Apparatus of Providing QoS and Scalability in the Deployment of Real-Time Traffic Services in Packet-based Networks are disclosed. The aim of the invention is to provide QoS for both realtime and non-real-time traffic streams.;The invention presents an architectural framework coupled with the functional apparatus necessary to deploy services like Voice over IP (VOIP) in a scalable way in spite of network limitations such as shortage in IPV4 addresses, NAT traversal, and the processor-intensive requirements of RTP termination. Methods to solve these problems associated with large-scale VoIP deployment by distributing application gateways are presented. More importantly, the approach serves to provide consistent broadband performance over access technologies which are prone to capacity degradation due to unregulated admission of real-time traffic streams like VoIP and IP Television.;The paper gives emphasis on broadband wireless because of its shared access mechanism.
