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 urn alarm is present.
