In this thesis, an efficient traffic flow admission control mechanism supporting DiffServ is proposed to provide QoS in MPLS networks. We propose a dynamic and flexible flow admission control for MPLS support of DiffServ to prevent the waste of resources. Ingress LSRs may collect information to find out the congested area using control messages exchanged in QoS routing. We exclude the congested...

Multiprotocol Label Switching (MPLS) is emerging as a flexible technology that can transport voice, IPv4, IPv6, layer 2 services (Frame Relay, ATM, Ethernet, etc.), and even PDH and SDH/SONET circuits over a single packet infrastructure, in a new attempt to solve the old problem of network convergence. MPLS traffic engineering, quality of service support (in combination with DiffServ), and fast...

Multicast support in a Multipro-tocol Label Switching (MPLS) network has yet to be deened. An MPLS network consists of label switching devices such as ATM. This document discusses both dense-mode and sparse-mode IP multicast within the context of MPLS networks. Unlike unicast routing, dense-mode multicast routing trees are established in a data-driven manner and it is not possible to topologica...

Multi-Protocol Label Switching is a technology that combines the simplicity of IP routing with the high-speed switching of ATM. Mobile IP is a protocol that allows users to move around and yet maintain continuous IP network connectivity. In this paper, we propose a scheme to integrate the Mobile IP and MPLS protocols. The integration improves the scalability of the Mobile IP data forwarding pro...

Today MPLS-TE is one of the hot technologies which every major carrier has selected for its network infrastructure. Some of the key reasons for the high level of interest in MPLS-TE include the requirements of critical network applications in the areas of link capacity and network connectivity. MPLS-TE is able to handle various paths along different routes to balance the traffic load between tw...

Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. This document proposes an automated mechanism for establishing tunnels between provider-edge routers in a VPN, but does not provide an automated mechanism for establishing security associations for these tunnels. Without suc...

Different optimization models presented on literature show optimization schemes over MPLS or GMPLS networks. However, it has not been showed models that optimize one or more parameters integrating these two types of networks. In this paper a multiobjective scheme for multicast transmissions from a source node to a set of destination nodes in MPLS passing through a GMPLS optical backbone is show...

A mechanism for BGP that helps minimize the negative effects on routing caused by BGP restart has already been developed and is described in a separate document ("Graceful Restart Mechanism for BGP"). This document extends this mechanism to minimize the negative effects on MPLS forwarding caused by the Label Switching Router’s (LSR’s) control plane restart, and specifically by the restart of it...
