US 2010/0146150 A1 · MANAGEMENT NETWORK FOR NETWORK MANAGEMENT, ITS MANAGEMENT METHOD, AND NETWORK ELEMENT USED THEREFOR

Abstract

A management network for managing networks managed individually by a plurality of groups, wherein authorization and unauthorization of access for supervision and control are automatically set. Each network element is assigned a TID, as a prefix, having a group ID identifying a group to which the network element belongs. Topology information considered from each network element to all network elements includes a group ID. When a group ID included in the received topology information matches the prefix of the TID assigned to its own network element, the source is registered at the authorized side of the access authorization list (step 1012), while when it does not match, it is registered at the unauthorized side (step 1016).

Dependent claims

A management method for managing a network comprising a plurality of network elements, comprising:

assigning, as a target ID identifying each network element forming a management network, the target ID including as part of it a group ID indicating belonging to a certain group to each network element forming the management network;
having each network element advertise advertisement information including the group ID to the entire management network;
and
having each network element extract a group ID included in the advertisement information when receiving the advertisement information, authorize access from a network element of a source of the received advertisement information when the group ID matches the group ID contained in the target ID assigned to its own network element, and not authorize access from a network element of a source of the received advertisement information when it does not match.

1 more element

A management method of a management network for managing networks individually managed by a plurality of groups, comprising:

assigning, as a target ID identifying each network element forming a management network, the target ID including as part of it a group ID identifying a group which manages each network element to each network element forming the management network;
having each network element forming the management network advertise advertisement information including the group ID of a group managing its own network element;
and
having each network element forming the management network validate an access authorization list when receiving the advertisement information including the group ID, register a network element that is the source of the received advertisement information at an authorized side of the access authorization list when the group ID matches the group ID contained in the target ID assigned to its own network element, and register it at an unauthorized side when it does not match.
