Embodiment Construction

[0060] As shown in Figure 4, Figure 5, Figure 6 and Figure 7, a dual-node interconnection topology is adopted in various network topologies. The ring network 100 and the Mesh network 200 respectively have two nodes connected to each other. Similarly, a dual-node intercommunication method can also be adopted between the Mesh network and the Mesh network. Figure 4 shows the topology structure of the interconnection of the ring network and the Mesh network, Figure 5 shows the topology structure of the interconnection of two ring networks through the Mesh network, Figure 6 shows the topology structure of the interconnection of two Mesh networks through a ring network, and Figure 7 shows the topology structure of the two mesh networks The interconnection topology between a Mesh network. In the following technical solution, two cases of the multiplex section protection ring and the subnet connection protection ring are considered for the ring network. For the Mesh network, two cas...

Abstract

The invention discloses an interconnection structure and a method for configuring path between the optical networks. The optical network includes a first network and a second network, the first network and the second network each has a number of nodes, a first node of the first network connects with a third node of the second network, a second node of the first network connects with a fourth node of the second network. The method comprises the steps of: setting-up a first path between one of the first node and the second node and another node of the first network; and at least by one link of the link between the first node and the third node and that between the second node and the fourth node, and by the first path, said another node of the first network communicates for path with another node of the second network. By the dual-node interconnection structure and the path configuration shceme of this invention between a ring network and a mesh network, and between mesh networks, the respective advantages of the ring network and the mesh metwork in regard to protection and restoration can be combined effectively, and the existing internetworking schemes between the rings are also compatible.

Description

technical field [0001] The present invention relates to the intercommunication structure, service configuration mode and service protection and restoration method between mesh (Mesh) network and ring (ring) network and between Mesh networks, and can be applied to backbone network, metropolitan area network and access network of optical communication net field. The ring network can be Synchronous Digital Hierarchy (SDH) / Synchronous Optical Network (SONET), Optical Add Drop Multiplexing (OADM, Optical Add Drop Multiplex) and Automatically Switched Optical Network (ASON, Automatically Switched Optical network); Mesh The network may be O / O type optical cross-connect equipment (OXC, Optical Crossconnect), O / E / O type optical cross-connect equipment, digital cross-connect equipment (DXC, Digital Crossconnect) and automatic switching optical network equipment. The intercommunication structure is used for service intercommunication and fault protection recovery between Mesh networks a...
