Embodiment:
Further specify technical scheme of the present invention below by embodiment.
Low-end switch is carried out the method for remote cluster management, many functionally similar low-end switch in the network are divided into a management domain as client, one runs on the stronger higher-end switch of CPU disposal ability and by a management agreement that is operated in management level the client exchange machine in this management domain is carried out remote cluster management as service end, described management agreement is divided into communication layers and two part of application management layer, it is network layer and transport layer that communication layers is positioned at the 3rd layer and the 4th layer of OSI seven layer protocol models, and this two-layer work is as a wholely handled together, be responsible for the communication between client and the service end; The application management layer is positioned at OSI seven layer protocol application of model layers, is responsible for the concrete management of service end to client.
As shown in Figure 1, be the level schematic diagram of this management agreement, this management agreement is divided into communication layers-communication protocol and application management layer one management agreement two parts.It is network layer and transport layer that communication layers is positioned at the 3rd layer and the 4th layer of OSI seven layer protocol models, and this two-layer work is as a wholely handled together, is responsible for the maintenance, data information transmission of the connection login of equipment, the control that connects, connection etc.Communication layers is supported the burst transmission and the overtime retransmission mechanism of data message, increased the reliability of communication, and the concrete function of communication kernel and equipment is irrelevant, has improved the independence of communication protocol.The application management layer is positioned at OSI seven layer protocol application of model layers, is responsible for concrete application management, Template Manager for example, management by synchronization, backup management etc.
As shown in Figure 2, the message structure for management agreement comprises field: destination address, source address, type, protocol header, data, CRC.Type field is used to discern this agreement, is different from other Ethernet protocol.Protocol header is used to define the agreement built-in message type (for example be login message, or login response message, or data message) of the message of this agreement.
Automatically find new equipment:
When equipment of new adding in network, it will send the logging request message, contain information such as device type, user name, implementor name in this message.The address of this message is a unicast address, this message can only be received by neighbor device, neighbor device adds the information of oneself after receiving this message, send again, so repeat, received by a server device up to this message, by this message server device just known this message path (topology) information of process, also just known the information of this equipment, server sends a back message using to this new equipment, and expression is logined successfully.Send the HELLO message later between server and this new equipment mutually and safeguarding this connection.
Cluster management based on template:
Service end is passed through the control mode of username and password with configuration packet.A user name is represented a kind of configuration.The user can in the light of actual conditions divide into groups remote equipment, each group has same username and password, in order to prevent that logging device from can not find the situation of self user name, management agreement is provided with a default user name user, password user, and the logging device that can not find user name so just can sign in to default user name.The keeper at first is configured this template, is template with the configuration set information under self behind the remote equipment login service end, and the configuration information of this template is downloaded to remote equipment.
Remote equipment signs in to server with user name, password, and the identical equipment of user name, password is as same group, the keeper can by revise user name, password is realized adding a group, breaks away from a group and creates one and newly organize.
Synchronously:
The configuration information of remote equipment is stored in server end, and does not rely on remote equipment, when equipment of new adding, withdraw a remote equipment or replace a remote equipment, all extract configuration information from server end.Download to remote equipment with the configuration information of preserving on the server, come to finish in batches the process of configuration, be called synchronously.Can carry out in both cases synchronously: carry out synchronously when device logs arrives server, perhaps carry out synch command and carry out synchronously.
Management agreement is supported two kinds of methods of synchronization:
Based on template synchronously
The keeper at first is configured the template under the remote equipment at local (server end), then with the download of information of template to remote equipment, this process be called based on template synchronously.Based on template synchronously, be that the control by user name, password realizes.This synchronously can be at an equipment, and also many or all equipment synchronously depend on keeper's operation.
Based on topology location synchronously
Management agreement provides the management function based on topology location at the regulatory requirement of real network.The port that upper level equipment (upper level equipment is server) links to each other with subordinate equipment is called receiving port.Remote equipment is step by step upwards up to server, the uplink port of self and the equipment that passes through thereof the receiving port sequence constituted the topology location of an equipment.It is the configuration information of the remote equipment of index that management agreement can keep with this topology in service end.If the remote equipment on certain topology location damages like this, replace the configuration that new equipment will obtain the equipment that has damaged from service end automatically with a new equipment.Thereby can reduce a large amount of maintenance works.
The server backup function:
The preservation device configuration information of server end can upload to main frame, backs up.When changing server or other server carried out initial configuration, can recover current running environment and remote equipment configuration information fully.
As shown in Figure 3, be a large-scale sub-district, office building network access layer structure, there are thousands of users to insert.User Access Layer links to each other with μ 24 (server) by μ 1024 low-end switch (client).
Scheme 1:
The user finished configuration file according to the network planning on the PC main frame before equipment is installed, download to server (μ 24), and selected the cluster management mode based on template.μ 1024 low-end switch equipment are installed back login automatically, and from allocation list, search own under the configuration information of template carry out synchronously, if there is no then from share template, obtain configuration information, whole like this configuration effort moment finishes, and is very much conveniently.
Scheme 2:
The user at first carries out based on template remote equipment μ 1024 low-end switch synchronously.The user carries out particular arrangement at server (μ 24) to the remote equipment (for example certain μ 1024 in the building 3 of sub-district two) of specific position then.After configuration is finished, configuration information is saved in server, and selects cluster management mode based on topology location.When changing remote equipment, configuration information can download to new equipment.
