Distributed Channel Access Control Method in WDM Ring Network

摘要

1. The art that the invention defined in the claims ; The present invention relates to a distributed channel will access control method in a WDM ring network. ; 2. SUMMARY OF invention to solve the ; The invention uses a cheap device compared with the use of multiplexing branch coupled distributed control system in the WDM network to access the channel by the tunable and tunable WADM device transmitter / receiver by, and its object is to fast channel access and ensure fairness between nodes can provide and increase the channel utilization and economically provide a distributed channel access control method of the effective WDM ring network in a WDM ring network that can be built . ; 3. Solution subject matter of the invention ; The present invention, in the wavelength division channel access control method between nodes in a multi-ring network, generates a transmission status table based on the information of each node receives a control packet Steps to; Transport packet determination step of determining a data packet transfer; And further comprising an access channel selection step of selecting a channel used to transmit the data packet, the node comprising a fixed wavelength tunable ADM and WADM device to access the channel. ; 4. An important use of the invention ; The present invention used to fight and tunable WADM system.
