摘要： Methods for, and network elements in, packet or optical transport networks are disclosed, including a network element comprising non-transitory computer readable medium storing computer-executable instructions configured as one or more software agents that when executed with computer hardware: determine a state of the network element, comprising comparing a current state of transient properties of the network element against a predetermined, expected state of the transient properties of the network element; and verify a state of other network elements or paths in the transport network by comparing a current state of one or more network-level constraints of the other network elements or paths against a predetermined, expected state of the one or more network-level constraints on the other network elements or paths. The computer hardware may further positively or negatively acknowledge received instructions to apply a configuration to the network element based on the determination and/or verification.

摘要： Methods and systems for determining data transport paths through data transport subnetworks include a method for receiving, by circuitry of a computer system, a service request message from an edge node coupled with the circuitry of the computer system, the service request message including information indicative of: a first unique identifier of an ingress port of a first core node, the first core node being within a transport subnetwork; a second unique identifier of an egress port of a second core node within the transport subnetwork; and a requested transport path bandwidth. The method further comprises determining, by the circuitry of the computer system, a transport path through the transport subnetwork between the first core node and the second core node based on the service request message; and forming the transport path between the ingress port of the first core node and the egress port of the second core node.
