Abstract

The present invention relates to methods and systems for enhancing the traffic carrying capacity of telecommunication networks, in particular those involving optical networks and dense wavelength division multiplexing (DWDM).

Claims

1. A method for enhancing the carrying capacity of a network, comprising the steps of:

detecting the level of traffic incident on the network; and

providing selective preference to different classes of traffic depending upon the level of traffic incident on the network.

2. The method of claim 1, wherein one of the classes of traffic is single hop traffic, and another one of the classes of traffic is multiple hop traffic.

3. A network router for use in routing traffic on a network, the network router comprising:

a processor detecting a level of traffic incident on a network and providing selective preference to different classes of traffic depending upon the level of traffic incident on the network.

4. A network router for use in routing traffic on a network, the network router comprising:

a processor detecting a level of traffic incident on a network and providing selective preference to different classes of traffic depending upon the level of traffic incident on the network.
