There has been significant recent work in increasing the capabilities of Ethernet switches and Ethernet forwarding models. As a consequence, the role of Ethernet is rapidly expanding into "transport networks" that previously were the domain of other technologies such as Synchronous Optical Network (SONET) / Synchronous Digital Hierarchy (SDH), Time-Division Multiplexing (TDM), and Asynchronous ...

The paper presents a fast and efficient mechanism for rerouting traffic when there is a link failure or congestion problem in Multiprotocol Label Switching (MPLS) networks. Our method uses a predefined, alternative Label Switched Path (LSP) in order to restore traffic and significantly improves the performance in comparison to similar, existing proposals. We show that our proposal is not only a...

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 specifies Operations and Management (OAM) requirements for Multi-Protocol Label Switching (MPLS), as well as for applications of MPLS, such as pseudo-wire voice and virtual private network services. Th...

This document describes a historical method for encapsulating Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) Path signals for transport across packet-switched networks (PSNs). The PSNs explicitly supported by this document include MPLS and IP. Note that RFC 4842 describes the standards-track protocol for this functionality, and new implementations must use RFC 4842 rather...

This document describes the applicability of Multiprotocol Label Switching (MPLS) to traffic engineering in IP networks. Special considerations for deployment of MPLS for traffic engineering in operational contexts are discussed and the limitations of the MPLS approach to traffic engineering are highlighted. Boyle, et al. Informational [Page 1] RFC 3346 Applicability Statement for Traffic Engin...

Increasing number of Internet users forced them to use popular services, television and telephone, to use the Internet as a medium to reach their customers. Organizations are now applying VoIP and MPLS for providing the convergence of voice and data communications over single network infrastructure. VoIP (Voice over Internet Protocol) usage all over their branches, this reduces a huge amount of...

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...

This document defines simple additions to the Link Management Protocol (LMP) to provide a control plane tool that can assist in the location of stranded resources by allowing adjacent Label-Switching Routers (LSRs) to confirm data channel statuses and provide triggers for notifying the management plane if any discrepancies are found. As LMP is already used to verify data plane connectivity, it ...

Users need high speed and low latency transmission for new applications. Since Ethernet is the dominant LAN technology, service providers wish to offer new Ethernet services as Layer 2 Virtual Private Network (L2VPN), to meet the requirements of these applications. MultiProtocol Label Switching (MPLS) is one of the most suitable technologies to deploy L3VPN and can also be used to realize L2VPN...

Email: [email protected] Abstract: This paper presents studies about Internet Protocol Television (IPTV) technology starting with its motivation that led to its birth and its great and current application. The article theoretical basis will present the description of mechanisms, standards and main protocols used to ensure a quality of service needed to the deployment of IPTV applications. Amon...
