AN EXCHANGE STRUCTURE AND A METHOD OF CONNECTION CONFIGURATION BETWEEN THE OPTICAL NETWORKS

摘要

The invention discloses an exchange structure and a method of connection configuration for the structure between the optical networks. The said optical network includes the first network and the second network, the first network and the second network have a number of nodes respectively, the first node of the first network connects with the third node of the second network, the second node of the first network connects with the fourth node of the second network, the method includes: establishing the first traffic channel between one of the first node and the second node, and another node of the first network; and at least by one of the connection between the first node and the third node, and the connection between the second node and the fourth node, and by the first channel, the said another node of the first network communicates with another node of the second network on traffic. By the double-node exchange structure and the traffic configuration means in this invention between a ring network and a mesh network, and between the mesh networks, the advantages of the ring network and the mesh network respectively at the aspect of the protection and the recovery are combined effectively, and the prior connection means between the ring networks is also compatible.
