traffic flows in a proper direction. This helps when you plan the traffic direction planning and
service configuration in future.

3.6.2 Signal Flow and Timeslot Allocation

To configure the two-fiber unidirectional MSP service, you can configure the services that need
to be added to the ring network on the source NE, to pass through the intermediate nodes, and
to be dropped from the sink NE if the MSP protection subnet is already created.
3.6.3 Per-NE Configuration Process
This topic describes how to configure the two-fiber unidirectional MSP service.
3.6.4 End-to-End Configuration Process
This topic describes how to configure two-fiber unidirectional MSP services.
3.6.1 Networking Diagram
The networking diagram of a single two-fiber unidirectional MSP ring is simple. When you
construct the network, follow a certain order to create and name these NEs and ensure that the
traffic flows in a proper direction. This helps when you plan the traffic direction planning and
service configuration in future.
