The present invention is based on concrete an application of Generic Attribute Registration Protocol (GARP) standard.As concrete application, universal network method for device registration of the present invention has also been followed general format and the coding of GARP.Use the log-in protocol of the inventive method to be called as universal network facility registration agreement (GNDRP).The inventive method is used a multicast message, and its medium access control (MAC) address will be applied for one from the address table that GARP reserves.The applied application IP addresses of the inventive method are 0180c2000022.In case the universal network facility registration function of an equipment is opened, it will reach the purpose of finding and safeguarding whole network topology structure in this way regularly to the equipment transmission logon message of adjacency.Describe the know-why and the implementation of the inventive method in detail below in conjunction with Fig. 1 to Fig. 4.
The functional module that realizes the inventive method on apparatus for network node is called as universal network facility registration protocol module, and this module requires to have every function as shown in Figure 1: i.e. command function, timer, protocol package acceptance and transmission, main task processing etc.
The command function module: the order of definition opening/closing GNDRP function, and to these orders of device command line pipe reason system registry.
Timer module: this module functions is the various timers in the management system, the inventive method has been used three kinds of timers, inserts timer (jointimer), release timer (leavetimer) and whole release timer (leavealltimer).Jointimer timer and leavealltimer timer only are provided with one in each node device, leavetimer is provided with one for each shown node device in the dynamic preparation table.In case use the node device (network equipment) of the inventive method to be connected into network, the jointimer timer is just controlled this node device and regularly sent logon message to its connection device, register the device attribute value of oneself in this article.When expiring, the Leavealltimer timer can make all from allocation list, delete by the node device that shows in the dynamic preparation table.The LeaveTimer timer is mainly used in Control Node equipment log-on message aging in the preparation table.If before the LeaveTimer timer expires, receive the logon message of particular sections point device, so just restart the timing of LeaveTimer for this node device, promptly do not wear out.To the main flow process of the processing of timer as shown in Figure 2.
Protocol package receiver module: if universal network facility registration function is opened, CPU in the node device need discern and handle the logon message that other adjacent devices send, this module is responsible for information extraction from logon message, and handles to main task processing module message queue transmission property parameters.
The protocol package sending module: in case a node device (network equipment) is connected into network, just timing sends logon message to other node device of its connection, and the device attribute parameter of registration oneself.This module is responsible for regularly the log-on message with oneself, and to send to each connection status be " connection " port (linkup).This process comprises the encapsulation logon message and calls two steps of bottom layer driving interface transmission logon message.
The main task processing module: this resume module logon message, this module receives message from other modules in the mode of message queue, handles accordingly according to the type of message, and handling process is as shown in Figure 3.
The employed logon message structure of the inventive method and the coding as shown in Figure 4, wherein:
Protocol label symbol coding: protocol identifier (Protocol ID) should be encoded into two bytes, is used for representing a signless binary number.Represent that with hexadecimal number its value is exactly 0 * 0001, it is used for indicating is the GARP protocol massages.
Attribute classification coding: Attribute class (Attribute Type) should be encoded into a byte, is used for representing a signless binary number.Attribute class is used for the classification of the applied attribute of banner message.Attribute class 0 as retention, all can not with 0 be come representation attribute class so any one GARP uses by GARP.Therefore, GNDRP uses the Attribute class that uses 0 * 01 expression oneself.
The attribute length coding: attribute length (Attribute Length) should be encoded into a byte, is used for representing a signless binary number.It equals the number of the shared byte of attribute, wherein will comprise a byte of attribute length, and a byte of attribute event.Legal attribute length should be between 2 to 255.
The attribute event coding: attribute event (Attribute Event) should be encoded into a byte, is used for representing a signless binary number.Value that allows and the meaning of their representatives are as follows:
0 * 02: insert (Joinln) incident: the property parameters of stating this attribute.
0 * 04: break away from (Leaveln) incident: the property parameters of nullifying this attribute.
0 * 06: revise (Modify) incident: the property parameters of revising this attribute.
0 * 00: all break away from (LeaveAll) incident: the property parameters of nullifying all properties in this message.
The property parameters encoded content, promptly the value of the inventive method Attribute domain should comprise: 9 kinds of the MAC Address of the adjacent node of the domain name in manufacturer's mark (ID) of attribute logging node device, device flag (ID), Hostname, Internet protocol (IP) address, medium access control (MAC) address, affiliated territory, the identity in affiliated territory, direct-connected physical connection, the local port numbers of connection etc.The coding of property parameters (Attribute Value) has different length according to different Attribute class.
End mark (End Mark) coding: end mark should be encoded into a byte, is used for representing a signless binary number.Its value is always 0.Other value is a retention, can not use.
The application process of the inventive method is described below by concrete example.In case a node device (network equipment) is connected into network, just regularly send universal network facility registration message to its connection device, and the device attribute value of registration oneself in message, " BE2024 " equipment (device id=0 * 0104) of manufacturer " FIBERHOME " (vendor id=0 * 0101) for example, main frame is called " Freelink-01 ", no IP address, and MAC Address is " 0 * 000209FD47 ", do not add any territory as yet, do not find any adjacent node equipment.Owing to be the device attribute of registration oneself, so during the encapsulation logon message, above-mentioned every host information is encapsulated in order as property parameters (attribute value), and the attribute event of each property parameters correspondence (attribute event) is 0 * 02, i.e. registered events.
Other node device in the network when the equipment of its connection sends logon message, is also received the logon message that miscellaneous equipment is sent in timing.Universal network facility registration module is responsible for resolving the logon message of receiving, after the certain hour, each node device can obtain the property parameters of its other node device that connects.Moreover, network-management application can also be set up a dynamic network topology structure preparation table that comprises all node devices of registering.
When the node device in the network is revised the node device attribute of oneself, will revise content transmission by logon message equally and give other node device.Only the attribute event of the property parameters correspondence that needs need be revised is set at 0 * 06 and gets final product.
If use the node device of the inventive method " to leave " network, through after the scheduled time, its immediate neighbor node equipment can not be received its logon message.Under this situation, assert that this node device has worn out.So this immediate neighbor node equipment is announced this variation to other node device.Equally also be to utilize logon message, nullify all property parameters values in the property parameters of aging node device correspondence therein, be about to the attribute event value and be set at 0 * 00, so other node device after receiving the logon message that comprises ageing information, the dynamic preparation table of can corresponding modify safeguarding.
Those skilled in the art as can be seen, the employed logon message of the inventive method belongs to a kind of protocol Data Unit in fact, this kind protocol Data Unit is applicable to the universal network facility registration agreement that adopts the inventive method.
Technology contents in the above-mentioned specific embodiment is not construed as limiting protection scope of the present invention.The protection range of universal network method for device registration of the present invention is limited by incidental claims.
