364 Realization of EOS (Ethernet Over SDH)

Nowadays, with the continuous development of the data service, the traditional Synchronous Digital Hierarchy (SDH) Network which adopts Time Division Multiplex (TDM) cannot meet the corresponding requirements. People hope all kinds of information can be put together to transmit in order to save the cost of transmission and network management. So the Multi-Service Transport Platform (MSTP) was put forward. The MSTP is mainly in the SDH line transport mode and has multi-interface, ATM, Ethernet and Voice etc. This paper study two business: managed bandwidth services and Access for IP/VPN Networks.
