Mapping of IntServ/RSVP reservations into MPLS domains
Abstract:
parameters to be used to obtain the required QoS for an Internet flow. After a reservation has been established using the Resource reSerVation Protocol (RSVP), each router classifies each incoming IP packet to determine whether it belongs to a QoS flow. The MultiProtocol Label Switching (MPLS) allows high-performing label switching of packets. Network traffic is then forwarded using a simple label. The Constraint-based Routing Label Distribution Protocol (CR-LDP) allows the definition of a Label Switched Path (LSP) with QoS constraints, that is to perform QoS classification using a single valued label. This paper proposes an efficient combination of the application-oriented IntServ QoS with the power of MPLS label switching, that is to define IntServ-like QoS services in MPLS domains. Using the mechanisms defined in this paper, a homogeneous end-to-end QoS is reached. Main
