Next Generation Network (NGN) is envisioned to be an internetworking environment of heterogeneous networks to offer next generation services anywhere, anytime. It integrates the services of 2G/3G/4G networks by incorporating IPv4/IPv6 into a single service platform with Multi-Protocol Label Switching (MPLS). Several efforts have been carried out by researchers to integrate MPLS technology into ...

BGP/MPLS VPN is a mechanism defined in IETF RFC 2547 that allows service providers to use their IP backbone to provide VPN services. This mechanism is based on using BGP to distribute VPN routing information to the routers in the backbone network and using MPLS to forward VPN traffic. MPLS tunnels are created dynamically when needed, which relieves service providers of pre-provisioning tens of ...

Problem statement: Traditional IP networks have many limitations such as routing tables, which can be complex and time consuming. These limitations affect the performance of the network in some applications of triple play services (i.e., voice, video and data) which are characterized as time sensitive applications. Thus, Multi Protocol Label Switching (MPLS) technology has been proposed to spee...

In an increasingly hostile environment, the need for security in network infrastructure is stronger than ever, especially for Multi-Protocol Label Switching (MPLS), widely used to provide most of the new-generation network infrastructure-level services in the Internet. Unfortunately, the MPLS control plane lacks scalable verification for the authenticity and legitimacy of signaling messages and...

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. Abstract This document presents a set of requirements for the establishment and maintenance of Point-to-Multipoint (P2MP) Traffic-Engineered (TE) Multiprotocol Label Switching (MPLS) Label Switched Paths (LSPs). There is no ...

In Programmable Virtual Network (PVN), network providers sell network resources including programmable/nonprogrammable nodes and links connecting the nodes to customers for building their virtual networks. PVN can use Multi-Protocol Label Switching (MPLS) for creating virtual channels and fast packet forwarding. By using special MPLS labels, PVN can identify customers’ packets that require proc...

MPLS (Multiprotocol Label Switching) provides interesting mechanisms to integrate network technologies like ATM (Asynchronous Transfer Mode) and IP (Internet Protocol) with QoS (Quality of Service). It is a next generation technology with a great interest in teaching of networks and communications in Telematics Engineering degrees. In this paper we show a simulator as an innovative and educatio...

This paper presents a review of QoS (Quality of Service) Routing algorithms and Load Balancing Techniques in MPLS Networks. MPLS has high lightened as the most promising technology for the internet to provide the speed and bandwidth guaranteed services. It is good to apply MPLS in an internet environment to make it efficient and get more customer satisfaction while using internet. In this paper...

MultiProtocol Label Switching (MPLS) is used today inside most large Service Provider (SP) networks. In this paper, we analyze the establishment of interdomain MPLS LSPs with QoS constraints. These LSPs cross diverse SP networks that may belong to different companies. We show that using the standard BGP route for the establishment of such LSPs is not sufficient. We propose two path establishmen...

This paper presents simulation and analysis of constraint-based routing (CR) with MPLS (multiprotocol label switching). MPLS is basically a fast forwarding scheme for the core of the Internet. Constraint-based routing computes routes that are subject to constraints to meet QoS (quality of service) requirements. Constraint-based routing with MPLS greatly enhances network utilization and enables ...
