3-DEGREE ROADM - COLORED & DIRECTIONLESS SCENARIO

Felipe Sevillano, Transport & Data Planning Department, TELECOM PERSONAL PARAGUAY

Many times there are services that require high reliability, so more than two paths are constructed in the network to have a better protection of the services. In this case I show a scenario that covers three paths using the ROADM feature and ASON in the optical layer in order to transmit services along paths in direction north, west or east as an example.

When services from the main path are interrupted due to a network failure, services can be switched to protection path if manually configure optical cross-connections between NEs, but if ASON is configured in the network, the rerouting function of this protocol (GMPLS) can automatically find the paths and create the optical cross-connections to ensure the service reliability.

In the 3-degree ROADM - colored and directionless scenario, the direction of services can be done in any of the three available paths independently but only the same wavelength can be used for service rerouting.

Below a picture that illustrate the functionality:
