<p>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 in response to network traffic between the first device and the second device. The first device and the second device are connected by one or more logical connections having a combined bandwidth capacity. A first rate at which data is to be transferred between the first device and the second device on the first connection is estimated, and whether the first rate exceeds the combined bandwidth capacity is determined. If the first rate exceeds the combined bandwidth capacity, a request signal is transmitted from a third device external to the optical transport network to a first transport network device of the optical transport network. The request signal indicates a request to create an optical trail across the optical transport network between the first device and the second device. It is determined whether an optical trail can be created across the optical transport network between the first device and the second device.</p> |
