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).

Routing and admission control with multiconstrained end-to-end quality of service in MPLS networks
Multiprotocol label switching (MPLS) networks require dynamic flow admission control to guarantee end-to-end quality of service (QoS) for each Internet protocol (IP) traffic flow. In this paper, we propose to tackle the joint routing and admission ...
Providing deterministic end-to-end fairness guarantees in core-stateless networks
IWQoS'03: Proceedings of the 11th international conference on Quality of serviceEnd-to-end fairness guarantee is an important service semantics that network providers would like to offer to their customers. A network provider can offer such service semantics by deploying a network where each router employs a fair packet scheduling ...
A New End-to-End Quality of Service Algorithm in DiffServ Networks
ICCEE '08: Proceedings of the 2008 International Conference on Computer and Electrical EngineeringDiffServ is assumed as a scalable solution for service differentiation in the internet. It applies differentiated behaviors on data packets for different quality levels on aper hop basis (PHB). However, it does not have any control on the traffic ...
