SIGNALING USING A USER DEVICE INTERFACE TO AN OPTICAL TRANSPORT NETWORK

摘要

A method of and system for creating an optical trail across an optical transport network between a first device external to the optical transport network and a second device external to the optical transport network. A request signal is transmitted from a third device external to the optical transport network to a first transport network device of the transport network. The request signal requesting a creation of an optical trail across the optical transport network between the first device and the second device. It is determined whether at least a first path across the optical transport network exists between the first device and the second device. If at least the first path exists, at least a first optical trail is created along the first path between the first device and the second device.
