Embodiment Construction

[0039] The technical method of this patent is implemented in the hierarchical switching network system constructed by patent 03120998.X, based on the node domain control framework provided by patent 03121527.O, and involves the management and control of internal network services.

[0040] In order to improve the reliability of tree-structured network and the scalability of node and link capacity, Hierarchical Switching Network (HSNET) proposes an expansion scheme based on node domains (or logical nodes) and logical links. The basic feature of topology extension based on node domains and logical links is that the nodes of the tree structure are replaced by node domains, the branches of the tree structure are replaced by logical links, and the tree structure is based on node domains and logical links. Organized into a logical hierarchical network, maintaining the characteristics of the hierarchical structure. Referring to Fig. 1, the node domain 1 is one of the basic elements of...

Abstract

The present invention provides one kind of internal service system for hierarchial exchange network and its management and control method, and belongs to the field of computer network technology. The internal service system for hierarchial exchange network has system frame attached to the hierarchial exchange network, and each node domain has one or several service nodes with services of different types except exchange nodes. On one hand, the management and control inside the node domain is realized via service protocol; and on the other hand, the mutual operation between node domains is realized via the interaction of service message. Thus, the internal service system for hierarchial exchange network can provide various internal services. The present invention ensures the discrepancy and variety of service while raising the network interacting performance, and is favorable to service management and network safety.

Description

technical field [0001] The invention belongs to the technical field of computer networks, in particular to a hierarchical switching network internal service system and its management and control method. Background technique [0002] A hierarchical switching network is a special network architecture constructed according to a hierarchical structure. Its topology is structured according to a hierarchical structure, and its address space is also allocated according to a hierarchical structure, and the layers of the topology and the layers of the address structure are strictly matched. It replaces IP Routing with IP Switching by redefining the network topology, the method of network address allocation, and the relationship between the two, avoiding routing operations, and realizing data packets according to hierarchical addresses. to exchange. The hierarchical switching network has the characteristics of high performance, scalability and manageability, and is fully compatible w...
