End-to-end quality of service in pseudo-wire networks

Published: 06 December 2011 Publication History

Abstract

Carrier-grade networks are complex systems that include several heterogeneous domains and support various types of services under specific Quality of Service (QoS) requirements. To tackle the problem of setting end-to-end connections across heterogeneous domains, the Pseudo-Wire architecture [1] allows to emulate some protocols (e.g. SDH, Ethernet, ATM, etc.) over MPLS. This emulation is achieved by encapsulation and decapsulation functions called adaptation functions. A path crossing heterogeneous domains must involve compatible functions so that datagrams are understandable by the source and target nodes (e.g. if Ethernet is encapsulated in MPLS by a node, it must be decapsulated by another).
