Virtual routing and management algorithm for QoS and security in internet

Abstract

The motivation for simultaneous providing QoS and security in the network will accelerate an introduction of new services, and is able to provide safe, secure access to the network resources, while allowing the resource is securely managed by end users needing with required QoS. This paper describes one approach to provide quality of service (QoS) guarantees in a network using secure networking mechanism. For provisioning of secured QoS in internet, additional routing and management mechanism are required through the logical architecture of overlay networking. It also suggests a novel algorithm to provide secure overlay networking, routing and forwarding mechanism, and admission and resource management algorithm to compute resource consumption amount and to evaluate its acceptability in the secured overlay network providing its QoS level is based on the discrete-time fluid flow process. And its results is applied to manage the virtual resource for the required security and QoS level and to make decision of a new flow admission in overlay network. © Springer-Verlag Berlin Heidelberg 2004.
