Related description of the present invention:
1, network management workstation is divided into application layer, operation layer, data Layer.Data Layer safeguards level cache, and operation layer safeguards L2 cache and pre-read management.Level cache is the MIB level buffer memory based on MIB aging characteristic.The L2 cache that operation layer is safeguarded is the operation layer buffer memory calculated based on business classification or the enterprising line time stamp of MIB form.If the various webmaster business of application layer need access equipment, all undertaken filtering (first request time stamp by operation layer L2 cache, again with corresponding timestamp comparison in operation layer buffer memory, judge whether operation layer is data cached consistent with equipment True Data, if consistent, just directly use data cached), avoid ineffective access.And read service related information in advance by pre-read management algorithm, raise the efficiency.In data Layer level cache, on similar time point, access a back end, the problem of repeated accesses mainly through solving two kinds of business based on the mode of data characteristics allocating cache effective time simultaneously.
2, the present invention includes EMS network management workstation and SNMP proxy module two parts.Wherein SNMP proxy module is a process of network element device, comprises a timestamp calculator.When SNMP proxy module time of receipt (T of R) stamp MIB request, calculate a timestamp response network management workstation according to the value of current MIB.
3, operation layer module refers to the data handling procedure that in network management workstation, operation layer realizes.Data layer module refers to the data handling procedure that in network management workstation, data Layer realizes.Application layer module refers to the data handling procedure of application layer digital display in network management workstation.
4, the effective time map configuration file of MIB buffer memory refers to and is configured MIB feature.Comprise the title of MIB, and the title correspondence MIB buffer memory effective time of MIB.
5, ttl threshold of router and timer threshold are determined according to actual conditions, and timer threshold can be configured to 5s.Ttl threshold of router is 3.
6, TTL chain refers to the directive linked data structure of band life span mark, i.e. the mapping that is associated with another business of business.
As shown in Figure 1, this device is divided into network management workstation and SNMP proxy module two parts.Wherein SNMP proxy module is a process of equipment, comprises a timestamp calculator.When the stamp request of SNMP proxy module time of receipt (T of R), the business datum corresponding according to the request of current time stamp calculates a timestamp response network management workstation.Network management workstation is divided into application layer module, operation layer module, data layer module.Data layer module safeguards level cache, and operation layer module safeguards L2 cache and pre-read management.Level cache is the MIB level buffer memory based on MIB aging characteristic.The L2 cache that operation layer module is safeguarded is the operation layer buffer memory based on business classification or the verification of MIB form enterprising line time stamp.If the various webmaster business of application layer module need access equipment, all filtered by operation layer L2 cache, avoid ineffective access.And managed by pre-read and read service related information in advance, raise the efficiency.In data Layer level cache, what mainly solve is that two kinds of business access a back end, the problem of repeated accesses on similar time point simultaneously,
The operation layer module buffer memory flow process of system as shown in Figure 2, application layer module initiates network element device information read requests, after operation layer module receives request, first judge whether to there is this network element device buffer memory, if do not had, direct access network element device, and upgrade network element device buffer memory and network element device cache-time stamp, if there is network element device buffer memory, then only need the timestamp request of initiating to read this business categorizing or form to SNMP proxy module, whether comparison is consistent with the timestamp in current cache again, if consistent, with regard to return cache data, if inconsistent, SNMP request is sent again to SNMP proxy module.Meanwhile, also pre-read request can be initiated to pre-read manager.
After data Layer receives the request of operation layer, read configuration effective time of MIB according to MIB configuration, then in data buffer storage, look into the MIB buffer memory seeing if there is correspondence, if do not had, then initiate request directly to proxy for equipment, if there is buffer memory, then whether the cache-time of comparison current cache is greater than the effective time of MIB configuration, if be not more than this time, with regard to direct return cache data, if be greater than, then think that MIB buffer memory is more outmoded, then initiate mib information request to proxy for equipment.
After receiving the pre-read request of operation layer, pre-read manager can be looked into according to pre-read configuration and see if there is pre-read relationship maps, if had, then initiates MIB read requests, and is labeled as pre-read request, arrange the life span of pre-read request.If no, then record raw requests traffic ID.There is a regular computational threads of service request correlation in pre-read, after calculating, on-the-fly modifies pre-read configuration and map.Reach according to user habit, the effect of intelligent pre-read.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
