Ethernet over SDH (EoSDH)

Ethernet over SDH (EoSDH) combines the packet-optimized Ethernet technology with the real-time-optimized TDM method from the Digital Synchronous Hierarchy (SDH). In the combination of both techniques the advantages shall be used and their disadvantages shall be avoided.

The realization of the EoSDH technology includes flexible bandwidth management with dynamic bandwidth allocation to the communication demand, physical network separation, delay-free data transport as well as the integration of the Ethernet interfaces into the Digital SynchronousHierarchy (SDH).

The platform used for EoSDH technology is based on SDH with Ethernet as the physical layer. EoSDH offers network operators an interesting alternative to MPLS, especially since real-time behavior is available and the quality of service( QoS) can be adapted.
