Ip-Based Virtual Private Networks And Proportional Quality Of Service Differentiation, Jingdi Zeng
Dissertations
IP-based virtual private networks (VPNs) have the potential of delivering cost-effective, secure, and private network-like services. Having surveyed current enabling techniques, an overall picture of IP VPN implementations is presented.
In order to provision the equivalent quality of service (QoS) of legacy connection-oriented layer 2 VPNs (e.g., Frame Relay and ATM), IP VPNs have to overcome the intrinsically best effort characteristics of the Internet. Subsequently, a hierarchical QoS guarantee framework for IP VPNs is proposed, stitching together development progresses from recent research and engineering work.
To differentiate IP VPN QoS, the proportional QoS differentiation model, whose QoS specification granularity compromises …
