The advantage of multi-protocol label switching (MPLS) is its capability to route the packets through explicit paths. But the nodes in the paths may be possibly attacked by the adversarial uncertainty. Aiming at this problem in MPLS Network, in this paper, we propose a novel mechanism in MPLS network under adversarial uncertainty, making use of the theory of artificial intelligence, at first, w...

In this article, Guarantee of Service (GoS) is defined as a proposal to improve the integration of Mission Critical Networking (MCN) services in the Internet, analyzing the congestion impact on those privileged flows with high requirements of trust and delay. Multiprotocol Label Switching (MPLS) is a technology that offers flow differentiation and QoS in the Internet. Therefore, in order to imp...

Multi-Protocol Label Switching (MPLS) is an alternative to integrate Internet Protocol (IP) routing and switching technologies because it provides end-to-end Quality of Service (QoS), guarantees traffic engineering, and support Virtual Private Networks (VPNs). However, MPLS must use path restoration schemes to guarantee the delivery of packets through a network. Considering that MPLS is a label...

Multicasting has become increasingly important with the emergence of Internet-based applications such IP telephony, audio/video conferencing, distributed databases and software upgrading. IP Multicasting is an efficient way to distribute information from a single source to multiple destinations at different locations. In practice IP is considered as a layer 3 protocol. Multiprotocol label Switc...

Due to the increasing multicast applications and high desire for its deployment, it seems that any new technology should support multicast. However; MPLS technology which enhances IP packet forwarding capability by using layer 2 switching still does not offer any special solution for multicast support. The main difficulty in supporting dense-mode multicast protocols like DVMRP and PIM-DM is lac...

This paper deals with Multi-Protocol Label SwitchingTraffic Engineering Routing (MPLS-TE Routing) Systems which offer key Traffic Engineering features, including optimization of resources utilization, Quality-of-Service (QoS) and Fast Recovery. Numerous MPLS-TE Routing systems have been defined in the past with their own advantages and drawbacks. This paper proposes a generic architecture for M...

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...
