Claim Text:
1. A method comprising: receiving a signal by circuitry of a first node from a second node, with the first node and the second node part of a connection oriented network adapted to use protocols to establish at least one sub-network connection to facilitate transfer of data between the first node and the second node, the first node and the second node utilizing Generalized Multiprotocol Label Switching (GMPLS) protocols, the signal having a message including parameters; and configuring the circuitry of the first node for sub-network monitoring of at least one characteristic of the sub-network connection by a sub-network monitoring algorithm executing on the first node with the parameters, wherein the connection oriented network is an optical transport network, wherein the signal comprises a sub-network connection establishment signal adapted to establish the sub-network connection and enable the sub-network monitoring, wherein the sub-network connection establishment signal comprises a first identifier indicative of an origination point of a tandem connection that is a starting point for the sub-network monitoring, a second identifier indicative of a termination point of the tandem connection that is an ending point for the sub-network monitoring, and a third identifier indicative of a layer associated with the tandem connection.
