This paper describes a simple parallel signaling protocol for connection management in ASON. The signaling procedure is discussed in detail and the signaling time is tested experimentally and compared to hop by hop signaling protocols. The result shows that the new proposal has a better time performance than the traditional protocols.
We make an extension to the label distribute protocol in order to realize optical connection management in automatically switched optical network. Its characteristics, such as the dynamic lightpath creation and deletion, and fast restoration are investigated and tested experimentally. How to handle failures occur during these two processes is also explained in detail. The experiment results are discussed and compared with others¡¯ previous work. The experiment setup which is made of four optical nodes and of mesh type network is also described in details in the paper.
