The current rapid growth in video content, music downloads and business Ethernet applications are driving a booming demand for network capacity, for both fixed and mobile operators. Therefore, the need for a cost efficient way to build and scale metro transport networks is paramount to the ongoing success of any operator.

Transmode’s answer to this challenge is the Native Packet Optical approach. Through its integration of key Layer 2 functionality into the optical (CWDM/DWDM) transport network it provides the scalability, efficiency, flexibility and manageability that are required for an affordable metro and metro/access network for today’s and tomorrow’s demands.

Some of the fundamental advantages of the Native Packet Optical approach are for operators to be able to “fill the pipes” in the metro network as efficiently as possible and to provide them with visibility of the services being transported in the Ethernet signals. This service awareness will eventually help monitor the SLAs at the packet level and make sure that the SLA sold is the SLA delivered.

The way Transmode’s Native Packet Optical approach enables these advantages is to make sure that digital wrappers are not used in the metro network until necessary. Wrappers hide what’s inside the Ethernet signal, such as the priority of the traffic and also hide the true utilization level, preventing aggregation and an efficient utilization of the capacity. Wrapper technologies, such as OTN, are often used in core networks where they are used more successfully, but in metro access networks the main data payload should be kept as native Ethernet instead of being wrapped. This will make the network service aware, simplify the structure and keep costs down.

By selectively deploying Native Packet Optical transport on a per wavelength basis the operator can ensure that investments in legacy systems are protected via the use of Multi-Service Muxponders to carry legacy and non-Ethernet services as efficiently as possible. Furthermore Native Packet Optical systems can interoperate smoothly with other network technologies such as OTN or MPLS-TP as all transport is based on standard Ethernet.
