In some scenarios, MPLS Transport Profile (MPLS-TP) pseudowires (PWs) (RFC 5921) may be statically configured when a dynamic control plane is not available. A fast protection mechanism for MPLS-TP PWs is needed to protect against the failure of an Attachment Circuit (AC), the failure of a Provider Edge (PE), or a failure in the Packet Switched Network (PSN). The framework and typical scenarios ...

MPLS enables service providers to meet challenges brought about by explosive growth and provides the opportunity for differentiated services without necessitating the sacrifice of the existing infrastructure. MPLS is a highly scalable data carrying mechanism which forwards packets to outgoing interface based only on label value .MPLS network has the capability of routing with some specific cons...

Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract RFC 3031 limits the MPLS archite...

MPLS security is an evolving issue which has been raised by many researchers and service providers. The basic architecture of MPLS network does not provide security services such as encryption. Therefore, MPLS does not protect the confidentiality of data transmitted. This paper provides a mechanism to enhance the security in MPLS networks by proposing a modified (k, n) Threshold Secret Sharing ...

Multiprotocol level switching is a promising technology which plays a vital role in new generation network by improvising QOS scalability speed and it also provide some other features like traffic engineering. MPLS came with a framework that is proficient for routing, switching and forwarding. MPLS has a permit to developing an environment of end-to-end circuits by using any transport protocol....

Various technologies about multi-path calculation for extensibility and failure restoration have been suggested as an increasing demand for QoS in MPLS networks. However, the MPLS networks have problems in extensibility for network traffic, failure restoration that waste usage of resources and much delay. Thus, we propose to H-MPLS networks recover failure in networks fast and support efficient...

This document specifies how Label Edge Routers (LERs) should behave when determining whether to MPLS encapsulate an IPv4 packet with header options. Lack of a formal standard has resulted in different LER forwarding behaviors for IPv4 packets with header options despite being associated with a prefix-based Forwarding Equivalence Class (FEC). IPv4 option packets that belong to a prefix-based FEC...

Multiprotocol Label Switching (MPLS) has gained momentum in recent years as an effective tool to provide Quality of Service (QoS) in a variety of networks. This has in turn created active interest in the area of recovery in MPLS based networks. A number of recovery schemes for MPLS domains have been proposed in recent years. However, the current schemes lack support for recovery in dynamic netw...

There can be a lot of QoS parameters that can improved in IP MPLS network Backbone such as bandwidth, CPU utilization, memory requirement, resources distribution and database optimization of each router in the backbone. In this paper, we have optimized database of each router by involving DR/BDR election on each interface so that all involved routers use that elected DR router as to communicate...

The paper provides a proposal for an MPLS-based transport network for future Radio Access Networks (RANs) and compares this with a regular IP-based transport network. Our MPLS-based approach takes into account the specific needs of current and future RANs especially with respect to QoS requirements and flexibility. In the paper we compare the MPLS-based solution with a regular IP-based network....
