METHOD FOR CONFIGURING END-TO-END LOWER ORDER ODU NETWORK TRAILS ACROSS OPTICAL TRANSPORT NETWORK

摘要

The disclosure relates to a method of configuring end-to-end ODUj (lower order ODU) network trails across OTN (Optical Transport Network), in which the tributary port number (TPN) of the lower order ODUj inside higher order ODUk is specified. The time-slot value associated with the TPN is not to be specified by the user. The time-slots are dynamically allocated on the transmit side. On the receive side, there would be a capability in the ODUk adaptation sink function to find the set of time-slots associated with the TPN based on the received multiplex structure identifier (MSI). That is for an ODUj entity with a fixed TPN, the transmitted time-slots can change and the receive end can detect this change and based on that de-multiplex the ODUj from the ODUk.
