MPLS is an emerging backbone technology for service providers, which is being deployed on a large scale in recent days. Using MPLS, service providers can deliver different types of services like TE, QoS and IP VPN along with adequate security according to the specific business demands, across either switched or routed networks. This paper deals with the current problems in service providers’ ne...

Multiprotocol Label Switching (MPLS) is an advanced forwarding scheme, which allows the network to achieve the Traffic Engineering (TE) objectives. When two or more MPLS nodes are connected via an ATM backbone merely composed of ATM switches, it is necessary to add some mechanisms to allow the label distribution and allocation between both nodes. In this paper a solution is proposed to integrat...

In this paper, we study multicast tree construction in MPLS network. We discuss the difficulty in combining multicast and MPLS in a network. We describe some MPLS proposals for the multicast traffic and we justify the need for defining a new protocol. Thereafter we propose MMT, the MPLS Multicast Tree protocol, which uses MPLS LSP** between multicast tree branching nodes in order to reduce the ...

In this paper, we extend NS-2 to simulate Micro-Mobile MPLS frameworks. The extension supports most of the important mechanisms used in the literature. The simulator is based on IEEE 802.11. The important mechanisms for IEEE 802.11 in our module are multi-channel, directional antennas, multiple interfaces, L2-handoff, L2-trigger, bicasting, pre-established LSP, and buffering mechanism. MPLS mod...

Various applications of MPLS make use of label stacks with multiple entries. In some cases, it is possible to replace the top label of the stack with an IP-based encapsulation, thereby enabling the application to run over networks that do not have MPLS enabled in their core routers. This document specifies two IP-based encapsulations: MPLS-in-IP and MPLS-in-GRE (Generic Routing Encapsulation). ...

MPLS is highlightened as the most promising technology for the integrated IP-over ATM backbone networks. Nowadays, one of the important practical issues in MPLS is the capability to provide Differentiated Services. For integrating IP and ATM with scalability, MPLS based ATM switch network can be available, especially for the fast Internet services adding Layer 3 routing module to the existing A...

Multiprotocol Label Switching provides a virtual path capability between packet (label) switches to efficiently carry differentiated services across the Internet. Additionally, MPLS has been enhanced with the capability to precisely engineer traffic tunnels to avoid congestion and utilize all available bandwidth in an efficient manner. This paper provides an extensive resource, serving the moti...

Multi Protocol Label Switching (MPLS) has been used to provide traffic engineering and high speed networking. MPLS is an evolving network technology. MPLS is a framework which is introduced by IETF. It is a differentiated and scalable framework. MPLS delivers end-to-end IP services with the use of simple configuration and management. Fault tolerance is an important Quality Of Service factor.
