- This paper describes the role of a standards-based Ethernet over SDH architecture that unites SDH, RPR and MPLS for the transport of Ethernet in QoS Switch/Router (QSR). One of QSR transport solution uses SDH as the physical layer and employs technologies such as GFP, VC and LCAS to enable transparent Ethernet over existing SDH infrastructure. Ethernet traffic can be carried over the RPR-enabled transport infrastructure using MPLS in QSR's EoS line card. In the aspect of the required SDH capacity the significant savings of capital expenditure are obtained from EoS and RPR-enabled overlay solution comparing to Ethernet point-to-point solution. EoS enables a service provider to offer Ethernet services efficiently by using existing SDH resources and to increase the value of existing SDH networks.
