Title

RD-QoS - Extensions to RSVP and DiffServ to Signal End-to-End IP Resilience Requirements

Keywords

INTERNETWORK PROTOCOL; QOS; NETWORK ARCHITECTURE

Abstract

Based on the growing commercial importance of the Internet network resilience is becoming a key design issue for future IP-based networks. In this paper an extension to existing Quality of Service (QoS) architectures is presented which integrates the signaling of resilience requirements with the traditional QoS signaling. We refer to this extended QoS model as Resilience-Differentiated QoS (RD-QoS). The applications signal their resilience requirements in addition to their QoS requirements to network edge. The network takes the resilience requirements into consideration for the resource management and traffic handling. At the border of MPLS domains, the resilience requirements can then be directly mapped to the appropriate MPLS recovery options. This approach allows an integrated end-to-end provisioning of resilience and QoS in an IP-based network employing MPLS.
