Embodiment
Core concept of the present invention is: increase IOID and solve the code redundancy problem in the data structure of mib object, adopt the method for Proprietary MIB object reorientation to solve the data redundancy problem.
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with drawings and the specific embodiments.
With the supporting software of the network equipment in, mib object is organized with a kind of tree, each node in this tree all is a mib object.Each node all has the identification name of a character style and the identification number of a digital form simultaneously.A typical mib object tree as shown in Figure 1.In order to visit a mib object, can use from the root node of tree to this mib object the identification name of intermediate node of process represent this mib object, for example in Fig. 1, iso.org.dod.internet.private.enterprises.enterprises-C.f unc 1-C has just represented a mib object.Mib object also can replace identification name with identification number.Like this, above-mentioned mib object can also represent that this numeric string that is used for identification nodes is exactly the OID of institute's identification nodes with 1.3.6.1.4.1.3.1.
In order to realize this tree, each node in the tree is represented by a data structure that all this data structure generally includes the several like this data fields of father node, OID, first child node and next brother node of its represented node.In the present invention, add a data field in this data structure, be called internal object identifier IOID, the IOID of Proprietary MIB object with identical function is identical.For example, in Fig. 1, supposing that the C of enterprise is OEM, is that A of enterprise and enterprise B are made the network equipment simultaneously.The Proprietary MIB object 1.3.6.1.4.1.2.1 of the Proprietary MIB object 1.3.6.1.4.1.3.1 of the C of enterprise and the Proprietary MIB object 1.3.6.1.4.1.1.2.1 of the A of enterprise and enterprise B is corresponding, their function is identical, and then these three mib objects have identical IOID.
In order to represent the corresponding relation of OID and IOID, need on the network equipment, set up the identifier correspondence table.With tree shown in Figure 1 is example, and a typical identifier correspondence table as shown in Table 1.
| OID | IOID |
| 1.3.6.1.4.1.3.1 | 1 |
| 1.3.6.1.4.1.1.2.1 | 1 |
| 1.3.6.1.4.1.2.1 | 1 |
| 1.3.6.1.4.1.3.2 | 2 |
| 1.3.6.1.4.1.1.2.2 | 2 |
| 1.3.6.1.4.1.2.2 | 2 |
| …… | …… |
Table one
Need to prove,, therefore only need add the IOID data field for the data structure of expression Proprietary MIB object owing to the code that redundant code is just handled the Proprietary MIB object may occur.Equally, in the identifier correspondence table, also have only the OID of Proprietary MIB object and the corresponding relation of IOID.
In addition, in order to realize that the mib object of identical IOID is done unified processing, also need on the network equipment, set up and handle correspondence table.A typical processing correspondence table as shown in Table 2.
| IOID | Operation | Processing module |
| 1 | A | 1A |
| 1 | B | 1B |
| 2 | A | 2A |
| 2 | B | 2B |
| 2 | C | 2C |
| …… | …… | …… |
Table two
In table two, suppose for IOID to be that 1 mib object has two kinds of operations, and be that 2 mib object has three kinds of operations for IOID.By table two as can be seen, for mib object,, so just can finish by identical processing module if the operation of carrying out is also identical with identical IOID.So just solved the redundancy issue of code.
Please refer to Fig. 2, Fig. 2 is the flow chart of method when the visit mib object of processing management information bank provided by the invention.This flow process comprises:
Step 201: receive the instruction that mib object is operated.
Instruction that mib object is operated normally sends to the network equipment by the webmaster in the SNMP network.In this instruction, comprise the OID of the mib object that will operate and the operation that will carry out at least.
Step 202: according to the OID of the mib object that will operate of instruction, the mib object that decision instruction will be operated still is public mib object for the Proprietary MIB object, if public mib object execution in step 203 then, otherwise execution in step 204.
Step 203: according to the OID of the mib object that will operate that comprises in the instruction and the operation that will carry out, move corresponding processing module, finish this flow process then.
Step 204:, in the identifier correspondence table, determine corresponding IOID according to specified OID in the instruction.
Step 205: in the operation correspondence table,, determine corresponding processing module according to IOID and the specified operation of instruction.
Step 206: operation processing module.
Setting up the correspondence table shown in table one and the table two, and after adopting handling process shown in Figure 2, with the supporting software of the network equipment in, only need a code that the Proprietary MIB object is handled.But, in software, still need to exist data corresponding to many parts of Proprietary MIB objects of each enterprise.In order to address this problem, can adopt the method for reorientation mib object provided by the invention.
Please refer to Fig. 3, Fig. 3 is the flow chart of method when the reorientation mib object of processing management information bank provided by the invention.
Still be example with the mib object tree shown in Fig. 1.Shown in Fig. 1 is mib object tree of the prior art, and the C of enterprise is OEM, is the A of enterprise and the enterprise B manufacturing network equipment.Be that example describes only below with A of enterprise and the C of enterprise.There is the Proprietary MIB object of the A of enterprise again in the Proprietary MIB object that had both had the C of enterprise in the MIB of prior art tree.The Proprietary MIB of the C of enterprise is to liking node 1.3.6.1.4.1.3.1, node 1.3.6.1.4.1.3.2 and node 1.3.6.1.4.1.3.3, and the Proprietary MIB of the Dui Ying A of enterprise is to liking node 1.3.6.1.4.1.1.2.1, node 1.3.6.1.4.1.1.2.2 and node 1.3.6.1.4.1.1.2.3 with it.These two groups of mib objects are one to one, and the function of the mib object that corresponds to each other is identical.Exist in the time of two groups of mib objects and just caused data redundancy.In the present invention, do not have in the initial version of software node 1.3.6.1.4.1.1.2 and under node.The C of enterprise adopts the method for processing management information bank provided by the present invention that mib object under the 1.3.6.1.4.1.3 is reoriented under the 1.3.6.1.4.1.1.2 when giving the A of enterprise with the network equipment.
The method of the processing management information bank that present embodiment provides may further comprise the steps when the reorientation mib object:
Step 301: the source node OID and the destination node OID that obtain the mib object that needs reorientation.
With first mib object 1.3.6.1.4.1.3.1 under the processing 1.3.6.1.4.1.3 is example, and its source node is 1.3.6.1.4.1.3, and destination node is 1.3.6.1.4.1.1.2.
Step 302: according to given destination node OID, whether judge in the mib object tree this node of physical presence, if exist, then execution in step 304, otherwise execution in step 303.
Step 303: create destination node.
In general, have a plurality of mib objects under the source node and need reorientation.When first mib object under the source node was carried out reorientation, the destination node of appointment did not exist, and therefore need at first create destination node.
In the present embodiment, when handling 1.3.6.1.4.1.3.1, destination node 1.3.6.1.4.1.1.2 does not exist, and therefore needs to create this destination node.
Step 304: will need the mib object of reorientation to take off and be articulated on the destination node from source node.
For the mib object that will need reorientation takes off and is articulated on the destination node from source node, at first need to revise data field in order in the data structure of representing this mib object, especially father node data field becomes destination node with the value of father node data field from source node.Secondly also need to revise data field in order in the data structure of expression and associated other mib objects of this mib object.For example, the mib object of reorientation is first child node of source node if desired, when taking off the mib object that needs reorientation, also need to revise the first child node data field in the data structure of representing source node so, the value that makes this data field is second child node; If there be not second child node, the value of just revising this data field is for empty.The mib object of reorientation also is first child node under destination node if desired, so when the mib object that will need reorientation is articulated to destination node, the value that also needs to revise the first child node data field in the data structure of expression destination node is the mib object that needs reorientation.The same in other relevant operations and the prior art for the operation of being carried out during node motion in the tree.
Step 305: the OID that revises the mib object that needs reorientation.
At this moment two kinds of situations are arranged, and a kind of situation is that first mib object 1.3.6.1.4.1.3.1 of source node 1.3.6.1.4.1.3 corresponds under the destination node 1.3.6.1.4.1.1.2 also is first mib object; It no longer is first mib object that first mib object 1.3.6.1.4.1.3.1 that another kind of situation is 1.3.6.1.4.1.3 corresponds under the destination node 1.3.6.1.4.1.1.2.Specifically be which kind of situation is according to the requirement of enterprise B decision.Therefore, the OID that revises the mib object that needs reorientation at first will be according to the OID of destination node, and next is also possibly according to the position of mib object under destination node that needs reorientation.
After executing this step, the new OID of mib object 1.3.6.1.4.1.3.1 is 1.3.6.1.4.1.1.2.1.
Whether step 306 is empty according to the value of the first child node data field in the source node data structure, judge whether all need the node of reorientation all to handle under the source node, if execution in step 307 then, otherwise return execution in step 304.
Step 307 finishes this handling process.
After mib object being reoriented on the new position, mib object originally just no longer is present in the mib object tree.That is to say, any moment, only there are the data of a Proprietary MIB object in the mib object tree, so just solved the data redundancy problem.
Need to prove, in the process of reorientation mib object, behind the OID that has revised mib object, if this mib object is a minor matters point on the tree, promptly this mib object also has child node, so just also needs further to revise the OID of child node under this mib object.Suppose that the former OID of certain child node under the mib object 1.3.6.1.4.1.3.1 is 1.3.6.1.4.1.3.1.1, then the new OID of this child node is 1.3.6.1.4.1.1.2.1.1.Sometimes, after a mib object is reoriented to new position,, except revising its OID as mentioned above, also need further to adjust its position to the child node of this mib object.For example, suppose that the former OID of first child node under the mib object 1.3.6.1.4.1.3.1 is 1.3.6.1.4.1.3.1.1, as the 3rd child node of mib object 1.3.6.1.4.1.1.2.1, the new OID of this child node is 1.3.6.1.4.1.1.2.1.3 under reposition; And the former OID of the 3rd child node under the mib object 1.3.6.1.4.1.3.1 is 1.3.6.1.4.1.3.1.3, and as first child node of mib object 1.3.6.1.4.1.1.2.1, the new OID of this child node is 1.3.6.1.4.1.1.2.1.1 under reposition.The OID that revises the child node of mib object in fact also is that execution in step 301 is to step 308.For example, in the adjustment process to node 1.3.6.1.4.1.3.1.1, being actually with 1.3.6.1.4.1.3.1 is source node, is destination node with 1.3.6.1.4.1.1.2.1, and execution in step 301 is to step 307.
Need to prove, in the process of mib object reorientation, need to revise the OID of mib object, but the IOID of mib object does not change.Like this, after mib object was relocated to new position from original position, though variation has taken place its OID, code still can carry out appropriate processing to mib object according to its IOID.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
