چکیده

As the Internet evolves, additional capabilities are required to ensure proper treatment of data [3], voice, video and other delay sensitive traffic [4]. MPLS enhances source routing and allows for certain techniques, used in circuit switching, in IP networks. This permits a scalable approach to handling these diverse transmission requirements. CR-LDP [1] is a simple, scalable, open, nonproprietary, traffic engineering signaling protocol for MPLS IP networks.

RFC 3214 LSP Modification Using CR - LDP

This document presents an approach to modify the bandwidth and possibly other parameters of an established CR-LSP (Constraint-based Routed Label Switched Paths) using CR-LDP (Constraint-based Routed Label Distribution Protocol) without service interruption. After a CR-LSP is set up, its bandwidth reservation may need to be changed by the network operator, due to the new requirements for the tra...

Improvement of performance in MPLS domains by using caching and aggregation of CR-LSP

Constraint-based routing (CR-LDP) extends the features of MPLS Label Distribution Protocol (LDP) working in conjunction with a wide variety of QoS scenarios and services including IP differentiated services, integrated services, traffic engineering, Asynchronous Transfer Mode (ATM) service classes and frame relay. When a large number of CR-LSPs are required a lot of CR-LDP signalling is needed:...

Using LDP Multipoint Extensions on Targeted LDP Sessions

Label Distribution Protocol (LDP) can be used to set up Point-to-Multipoint (P2MP) and Multipoint-to-Multipoint (MP2MP) Label Switched Paths. However, the specification for the Multipoint Extensions to LDP presupposes that the two endpoints of an LDP session are directly connected. The LDP base specification allows for the case where the two endpoints of an LDP session are not directly connecte...

Applicability Statement for Restart Mechanisms for the Label Distribution Protocol (LDP)

Multiprotocol Label Switching (MPLS) systems are used in core networks where system downtime must be kept to a minimum. Similarly, where MPLS is at the network edges (e.g., in Provider Edge (PE) routers) [RFC2547], system downtime must also be kept to a minimum. Many MPLS Label Switching Routers (LSRs) may, therefore, exploit Fault Tolerant (FT) hardware or software to provide high availability...
