IP Network Design With End-to-End QoS Constraints: The VPN Case
Overview The traditional approaches to optimal design and planning of packet networks focus on the network-layer infrastructure, thus neglecting end-to-end Quality of Service (e2e QoS) issues, and Service Level Agreement (SLA) guarantees. The challenge in the area is how to devise reasonable packet network design methodologies that allow the choice of the most adequate set of network resources, subject to e2e QoS constraints and, at the same time, consider the traffic dynamics of today's packet networks. This paper describes a simple methodology to tackle the packet network design problem, and illustrate an example of its application to the optimization of link capacities and routing in a corporate Virtual Private Network (VPN), where traffic is mostly due to TCP connections.
