Description
Technical field
The present invention relates to technical field of the computer network, particularly a kind of method and apparatus that makes up terminal topology.
Background technology
The computer ways of connecting is called " network topology structure ".Network topology is meant the physical layout with transmission medium interconnection various device, and particularly how the position of computer distribution and cable are by them.Network topology has very strong intuitive, in network topology, can clearly illustrate the physical connection of equipment, and represents the attribute information of distinct device by different patterns, different colors.Because what network topology showed is physical equipment, so the carrying of whole network topology is the related service of equipment control, for example: IP (Internet Protocol, Internet Protocol) topological diagram.The IP topological diagram topological diagram that to be system draw automatically according to the subnet in the IP View and equipment has demonstrated network configuration and state informations such as annexation between each subnet and the equipment, Link State, equipment state in the IP topological diagram.IP View is used for the subnet and the equipment of display network, can check equipment in the subnet and the operation that equipment is correlated with by IP View.The two etale topology figure topological diagram that to be systems draw automatically according to the equipment in the subnet has demonstrated network configuration and state informations such as two layers of annexation between each equipment, Link State, equipment state in two etale topology figure.In addition, topological diagram also can demonstrate unknown MAC (Media Access Control, the medium access control) zone that annexation is arranged with equipment.Simultaneously, equipment state and Link State all can keep real-time update, make things convenient for the user to observe current network condition.
From the description of above topology figure, as can be seen:
(1) existing topological diagram all is the topological structure that removes display network from the angle of the network equipment, not the access user of display terminal;
(2) existing topological diagram lacks inserting layer service and access user's management, and carrying inserts the business of user management.Even if in topological diagram, show PC (Personal Computer, PC), also only be that PC is managed as equipment, do not focus on terminal use's management;
(3) existing topological diagram does not focus on business, and only from physical network, the node of network does not have related with business;
(4) existing topological diagram with the access security control of the network equipment and user's access behavior management combination, does not lack the concentrated controling management to user terminal, can not improve the active resistivity of network.
Along with rapid development of Internet, Network Management is begun to extend to the terminal use of Access Layer from the management to the network equipment.The Internet Access Layer is the interface that direct user oriented inserts, face a lot of unthinkable environment, and the access layer equipment cost is low, various in style, the place disperses, the inconvenience management, the scope of the influence that goes wrong is little, and a large amount of repetitive operation also causes the ignorance to Access Layer safety management work easily.Along with the sharp increase of network access user quantity and increasingly serious security threat, existing network management based on equipment control can't adapt to existing network condition.Mainly show:
(1) user's safe condition is known nothing, defensive measure is cured the symptoms, not the disease;
(2) can't in time respond threat from local area network (LAN) inside;
(3) can't insert the user to terminal and carry out access control effectively;
(4) can't the network usage behavior that terminal inserts the user be managed.
Therefore, the shortcoming of prior art is: the access user that existing topological diagram can not display terminal, existing network management lacks inserting the management that layer service and terminal insert the user, lacks the concentrated controling management to user terminal, can't improve the active resistivity of network.
