Protection performance components in MPLS networks
In this paper a new methodology to evaluate the protection performance of some existing mechanisms for establishing quality of service network paths with protection is presented. In order to evaluate the protection degree of a network, different components, such as protection parameters (packet loss and restoration time), or network parameters and constraints (link failure probability and netwo...
متن کاملEconomical protection in MPLS networks
The growth of Multi-Protocol Label Switching (MPLS) as the emerging choice for provisioning and managing core networks has placed significant emphasis on MPLS based recovery mechanisms. The present global protection frameworks require extensive involvement of Label Switching Routers (LSRs) in the protection framework. The LSRs are involved in failure propagation and maintenance of information r...
متن کاملDifferentiated Quality-of-Protection Provisioning in Optical/MPLS Networks
This paper investigates the problem of dynamic survivable lightpath provisioning against single node/link failures in optical mesh networks employing wavelength-division multiplexing (WDM). We present a new approach to provisioning lightpath requests according to their differentiated quality-of-protection (QoP) requirements. We focus on one of the most important QoP parameters, namely protectio...
متن کاملMPLS Transport Profile (MPLS-TP) Linear Protection
This document is a product of a joint Internet Engineering Task Force (IETF) / International Telecommunications Union Telecommunications Standardization Sector (ITU-T) effort to include an MPLS Transport Profile within the IETF MPLS and Pseudowire Emulation Edge-to-Edge (PWE3) architectures to support the capabilities and functionalities of a packet transport network as defined by the ITU-T. Th...
متن کاملEnd-to-End Protection Switching Mechanisms for MPLS Networks
In this paper we propose and investigate several end-to-end (e2e) protection switching mechanisms with application in Multiprotocol Label Switching (MPLS) networks. In case of local outages, the traffic of affected paths is switched to other e2e paths. In this case, Quality of Service can only be provided if sufficient extra capacity is available on the backup paths. If backup capacity can be s...
