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.

Method for configuring end-to-end lower order ODU network trails across optical transport network

The various embodiments herein provide a method and system for protecting multiple work ODU failures using a higher capacity protect ODU in an Optical Transport Network. The method for protecting multiple work ODU failures in an Optical Transport Network comprising steps of detecting signal failures in at least one of a plurality of work ODUs, requesting for release of one or more time-slots for a defective work ODU and allocating the one or more time-slots of a low priority traffic from the protect ODU in an incremental manner of priority. The method apply a TPN based policy for defining lower ODUs, performs handshaking between the transmit and downstream ends using the protocol provided, defines the role and behavior of the various system components and the service requests and performs an automatic lockout of protection for the work ODU in which an UDI alarm is present.
