Description

A kind of method and network equipment that generates management information base tree
Technical field
The present invention relates to network management technology, particularly relate to the method and the network equipment of a kind of generation management information bank (MIB, Management Information Base) tree.
Background technology
In network, the object identifier (OID, Object Identifier) of mib object and this mib object can be set usually at each concrete function characteristic of the network equipment.When needs manage the network equipment, visit specific mib object in the network equipment by OID, thereby finish specific management function.Such as, interface type characteristic at the network equipment is provided with mib object 1, like this, and when webmaster need be understood the interface type characteristic of this network equipment, only need the OID of this mib object 1 on this network equipment of visit, the network equipment then can offer webmaster with the interface type characteristic information of self.
Comprise public MIB object and proprietary mib object in the network equipment.Wherein, definition in RFC, be public MIB by the shared mib object of all-network equipment manufacturers, each is self-defined, only the mib object for own equipment use is proprietary MIB by network device manufacturers.In the network equipment, different public MIB objects organize together with tree structure, form the public MIB tree, and different proprietary mib objects also organize together with tree structure, form proprietary MIB tree, and public MIB tree and proprietary MIB set the final overall MIB tree that forms.Provided the schematic diagram that public MIB tree and proprietary MIB tree are combined into overall MIB tree among Fig. 1.Because mib object organizes together with tree structure, therefore, be that visualization is understood, below mib object is referred to as the MIB node.
At present, for a network equipment, tend to exist (OEM, OriginalEquipment Manufacturer) enterprise of original equipment manufacturer and two kinds of roles of target enterprise.Wherein, target enterprise is the enterprise that really need have the network equipment, and OEM enterprise is the enterprise that produces the network equipment for target enterprise.Like this, in the network equipment,, will preserve the proprietary MIB tree of target enterprise and the proprietary MIB tree of OEM enterprise for proprietary MIB tree.When the network equipment need form overall MIB tree, at first select to be articulated to proprietary MIB tree on the overall MIB tree according to the target corporate identify, set with public MIB then and be combined to form overall MIB and set.But, owing to have the proprietary MIB node of finishing said function in a large number in the proprietary MIB tree of different target enterprise and OEM enterprise, therefore, in the network equipment, preserve each proprietary MIB tree of different target enterprise and OEM enterprise simultaneously, a large amount of repeating data codes then can occur, thereby cause the problem of data redundancy.
The method that prior art solves the data redundancy problem is to adopt the re-positioning technology of proprietary MIB node.In the network equipment, only preserve the proprietary MIB tree of OEM enterprise, and no longer preserve the proprietary MIB tree of each target enterprise.When the network equipment is initialized, on overall situation tree, articulate the proprietary MIB tree of OEM enterprise, then the proprietary MIB node in the proprietary MIB of the OEM enterprise tree is reoriented to current specific target enterprise from OEM enterprise, thereby the proprietary MIB tree of OEM enterprise is converted to the proprietary MIB tree of current specific objective enterprise.Fig. 2 has provided the schematic diagram of proprietary MIB node re-positioning technology.OEM FLAG among the figure is a corporate identify, determines target enterprise with this.MIB node re-positioning technology is described in application number is Chinese patent application in 200610057458.6.
Though re-positioning technology has solved the problem of data redundancy, but when the proprietary MIB rime of public MIB tree and OEM enterprise is received overall situation tree, finish MIB module tree certain management function, that form by a plurality of proprietary MIB nodes for each, it all is root node from overall situation tree, be that node i so among Fig. 1 and Fig. 2 begins, according to the sequential access MIB tree of child node behind the first father node, up to the position that articulates of finding this MIB module tree.In practice, therefore the MIB module tree huge amount that the proprietary MIB tree of public MIB tree and OEM enterprise is corresponding, all begins to search the way that articulates the position from the root node of overall situation tree for each MIB module tree, need to consume more system resources, greatly reduce the operational efficiency of the network equipment.
In re-positioning technology, the OEM enterprise defining its realize the proprietary MIB module (corresponding to the structure overall situation tree time proprietary MIB module tree) of all-network management function, but, only provide a part wherein when target enterprise provides.Yet, re-positioning technology is when being converted to the defined overall situation tree of OEM enterprise the overall situation tree of current specific objective enterprise, do not provide a kind of effective transcoding filter mechanism to come when conversion the MIB module tree of non-current specific objective enterprise is filtered, thereby cause proprietary MIB tree structure and the inconsistent problem of current specific objective enterprise mib document definition finally changed out on the network equipment.
At last, re-positioning technology can't provide method in common to realize revising at the proprietary MIB node of target enterprise the node name of MIB node, only be when the node name of input and output mib object, to carry out interim conversion, the irregular special MIB node of name that this conversion can't processing target enterprise more or less exists.
