KR20010011277A - Sharing Method For Agent Management Object Information - Google Patents

Abstract

PURPOSE: A method for sharing agent management object information is provided to apply a management information base(MIB) of an agent to a discovery object class recommended in an international telecommunications union-telecommunication standardization sector(ITU-T), thereby easily transmitting information of a management object to a manager and to share the information of the management object regardless of manufacturing companies of a management system. CONSTITUTION: Management object configuration information of a switching system is received by a request of a network factor interface in an agent system. The management object configuration information is processed as an intermediate file to be stored. The stored file is formed as a management information tree(MIT). If a manager process requests object information for being shared, to the agent system with an M-action through a common management information protocol(CMIP), the agent system extracts a discovery object relating to the request to transmit the request. The discovery object extracts management object information of a management system from a self MIT, and transmits the management object information to the management system by including a name and an ID. The management system stores the management object information in a memory area, and shares the management object information.

Description

Sharing method for agent management object information

The present invention is to share the management object information for interworking between the Manager (Agent) and the Agent (Agent) forming a Telecommunication Management Network (TMN) in the TDX-ATM (Time Division Exchange-Asynchronous Transfer Mode) exchange system The method relates to the management information base (MIB) in the agent, in particular, by applying the Discovery Object class recommended in the ITU-T X.750 standard to easily convey information of the management object to the administrator. The present invention relates to a method of sharing agent managed object information that enables sharing of managed object information regardless of the production company of the manager system.

Typically, in a TDX-ATM switching system, the communication management network (TMN) is a remote management network over the network, and management commands are required to agents over the network through the administrator graphical operator interface, which requests are sent to the administrator through the network and the operator interface. The result is output to the manager system, and the manager system is notified of the change of the management information tree (MIT) by the notification function of the agent system and output through the operator interface. As shown in FIG. The agent system 20 connecting the exchange system 30 is configured to share management object information by the mutual interaction between the manager system 10 and the agent 20 through the manager system 10 and the M-GET.

In the manager system 10, a remote procedure call (RPC) is generated by generating a signal for sharing static management object information at initialization before the manager system 10 is connected to the agent system 20. Requests to the agent system 20 through a remote procedure call, and stores the static managed object information received from the agent system 20 through a remote procedure call (RPC) in its own memory area, and the manager system 10 and the agent system. The manager process 11 is provided which stores the dynamic management object information received according to the request through the M-GET in its memory area while the 20 is connected.

In addition, the agent system 20 is responsible for the transmission and reception of dynamic management object information through the M-GET and the manager system 10, and in charge of the operation and maintenance management of system resources according to the information of the management object to be transmitted and received The memory area 23 may request configuration information from the agent process 21 and the exchange system 30 connected in the initial state, and then use the information of the received exchange system 30 at the time of initialization of the agent system 20. And a common management information protocol (CMIP) and a graphical user interface required through a remote procedure call (RPC) from the manager process 11 of the manager system 10. Network element interface (22: Networ) for reading the configuration information file required for the GUI from the memory area 23 and transmitting it to the manager process 11 of the manager system 10; k Element Interface (NEIF).

In addition, the agent process 21 reads configuration information of the file stored in the memory area 23 to form a management information tree (MIT).

The operation of executing management object information sharing between the manager and the agent in the TDX-ATM switching system communication management network having the above functions is as follows.

First, in order to create an intermediate file for sharing static configuration information in the initialization state before the manager system 10 and the agent system 20 are connected, the network element interface 22 of the agent system 20 is connected to the switching system 30. After requesting the configuration information of the management object on the side, the configuration information of the management object received by the switching system 30 is stored in a file in the memory area 23 so as to be used for its initialization.

At this time, the file stored in the memory area 23 is composed of the configuration information of the exchange system 30 and the information which knows the name or type and ID.

Thereafter, the agent process 21 should generate objects to be managed in the future upon initialization. To this end, the agent process 21 reads file information on the management object component of the switching system 30 stored in the memory area 23 and manages the management information. It is formed as a tree (MIT).

The management objects created above abstract the components of the exchange system 30 and should have the components of the exchange system 30.

As described above, the manager process 11 in the manager system 10 calls a remote procedure while the agent process 21 forms a management information tree (MIT) for a component of a managed object of the switching system 30. (RPC) requests configuration information of management objects required for common management information protocol (CMIP) communication and graphical user interface (GUI) to the network element interface 22 side of the agent system 20.

When the configuration information request signal of the management object is detected through the remote procedure call (RPC) on the network element interface 22 side of the agent system 20 as described above, the network element interface 22 searches for the memory area 23. The file 'MODATA_INFO, LOG_INFO' containing the configuration information of the management object is read and then transmitted to the manager process 11 side in the manager system 10 through a remote procedure call (RPC).

At this time, the manager process 11 forms the configuration information of the management object received from the agent system 20 into static configuration information composed of a linked list in its memory area, thereby forming a common management information protocol with the agent 20. (CMIP) When the communication or the graphical user interface (GUI) is initialized to provide the configuration information to create a shape window of the switching system (30).

When the manager system 10 and the agent system 20 are connected while the static configuration information between the manager system 10 and the agent system 20 is shared as described above, the manager process 11 and the agent process 21 are connected. Shares the dynamic configuration information through the M-GET and stores it in its memory area.

As described above, in order to share static managed object configuration information between a manager system and an agent system in a conventional communication management network, there is no standard because information of the agent system is read through a remote procedure call (RPC) not implemented by the recommendation. When used in conjunction with the management system of other manufacturers there was a problem that can not be used due to lack of mutual compatibility.

In addition, when the management system and agent system are connected, the dynamic management object configuration information is shared, because M-GET is used, it takes a lot of time. there was.

The present invention has been made in view of the above-mentioned general problems, and an object thereof is to discover a discovery object class recommended in the ITU-T X.750 standard for sharing management object configuration information between a manager system and an agent system in a communication management network. It is applied to the management information base (MIB) in the system, and the sharing of the configuration information is simplified through M-ACTION to improve the efficiency of the shared information processing procedure of the management object configuration between the manager system and the agent system, and the managed object through the standard. This is to maintain compatibility regardless of the manager system linked by sharing configuration information.

The present invention for achieving the object as described above, in the management object sharing method between the management system and the agent system in the communication management network of the ATM switching system, by applying a discovery object class to the management information base in the agent system, The manager system may share management object configuration information of the agent system through M-ACTION.

The present invention also provides a process for processing and storing management object configuration information of a switching system received by a request by a network element interface means in an agent system as an intermediate file, and forming the stored file into a management information tree (MIT); Requesting, by the manager process, object information for sharing to the agent system by M-ACTION through a common management interface protocol; The agent system extracts a discovery object for the request of the manager system and transmits a request for object information for sharing the manager system; Receiving the object information request of the manager system, extracting the management object information requested by the manager system from its management information tree and transmitting the extracted management object information to the manager system including the name and the ID; The manager system receiving the agent's response stores the received management object's information in its memory area to share management information.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As can be seen in Figure 2, the TDX-ATM switching system according to the present invention is a communication management network (TMN) is composed of an agent system 20 and a manager system 10 to connect the switching system 30, the manager M-ACTION is used to share configuration information of a managed object between the system 10 and the agent 20.

The agent system 20 is responsible for the transmission and reception of dynamic management object information through the M-ACTION with the manager system 10, and in charge of the operation and maintenance management of system resources according to the information of the management object to be transmitted and received Memory for requesting configuration information from the agent process 21 and the exchange system 30 connected in the initial state, and then using the management object configuration information of the received exchange system 30 at the time of initialization of the agent system 20. A network element interface 22 for storing a file in the area 23 and an agent process 21 for reading configuration information of a file stored in the memory area 23 and generating a management information tree (MIT). .

In the present invention having the functions described above, an operation of sharing management object configuration information between the manager system 10 and the agent system 20 will be described with reference to FIGS. 2 and 3.

First, in order to create an intermediate file for sharing of static configuration information in an initialization state before the manager system 10 and the agent system 20 form a federation, the network element interface 22 of the agent system 20 is connected to a switching system ( After requesting the configuration information of the management object to the side 30, the configuration information of the management object received by the switching system 30 is stored as a file in the memory area 23 so as to be used for its initialization.

At this time, the file stored in the memory area 23 is composed of the configuration information of the exchange system 30 and the information which knows the name or type and ID.

Thereafter, the agent process 21 should generate objects to be managed in the future upon initialization. To this end, the agent process 21 reads file information on the management object component of the switching system 30 stored in the memory area 23 and manages the management information. It is formed as a tree (MIT).

As described above, in the state where the management information tree (MIT) for the management object configuration information of the switching system 30 is formed in the agent process 21, the manager process 11 receives the management object configuration information of the agent process 21. When the agent process 21 requests 'mITSearch action' for the discovery object object by using the M-ACTION 1 of the common management information protocol (CMIP) to the agent process 21, the agent process 21 is an administrator process 11. The M-ACTION request is delivered by searching for a discovery object among the managed objects according to the M-ACTION request.

At this time, the discovery object extracts the configuration information of the requested management object, forms the name or type and ID of the object as a response, and then transmits the information to the manager process 11 through the agent process 21.

In addition, when the manager process 11 initializes the discovery object, as shown in FIG. 4, an inheritance tree and a containment tree are generated.

The information authorized from the manager process 11 in the management information tree MIT, which is the instant information base MIB, is as follows.

ActionArgument :: = SEQUENCE

{

baseManagedObjectClass ObjectClass,

baseManagedObjectInstance ObjectInstance,

accessControl [5] AccessControl OPTIONAL

synchronization [6] IMPLICIT CMISSync DEFAULT bestEffort,

scope [7] Scope DEFAULT baseObject,

filter CMISFilter DEFAULT and {},

actioninfo [12] IMPLICIT Actioninfo

}

Actioninfo :: = SEQUENCE

{

actionType ActionTypeld,

actioninfoArg [4] ANY DEFINED BY actionType OPTIONAL

}

In the above, 'ActionAqument' is received by the agent process 21 from the manager process 11 and requests only 'ActionInfoArg' from the discovery object.

'ActionInfoArg' becomes 'MITSearch' which is 'Action Reqest Syntex' of 'mitSearch Action', which is as follows.

MITSearch :: = SEQUENCE {

base ObjectInstance,

discoveryScope Scope,

classRequest BOOLEAN DEFAULTFALSE

}

Here, when requesting all management information tree (MIT) information, the request statement selects 'base' as 'managedElementR1' which is the root of the management information tree (MIT), and 'discoveyScope' is all management information tree (MIT). Catch 'scope' to include everything)

The data type for this is as follows.

Scope :: = CHOICE

{

level INTEGER

{baseObject (0),

firstLevelOnly (1),

wholeSubtree (2)},

individualLevels [1] IMPLICIT INTEGER,

baseToNthLevel [2] IMPLICIT INTEGER

}

In addition, in order to make a response according to the above 'Action' information, the Instant Discovery object analyzes the managed objects constituting the Management Information Tree (MIT) in turn, analyzes the attributes of each object, and then deletes the specific object. Store the name, type, and ID as a string in 'pString' in the form of a name.

This creates a series of sub-entities of the 'RootedNameTree, which are implemented through the following data types.

MITSearchResponse :: = SET OF RootedNameTree

NameTree :: = SEQUENCE {

rdnInfo RDNInfo,

Subordinates SET OF Name Tree OPTIONAL}

RNDInfo :: = SEQUENCE {

rdn RelativeDistinguishedName,

moClass GdmoObjectClass OPTIONAL}

RootedNameTree :: = SEQUENCE {

rootObject ObjectInstance,

classOfRoot GdmoObjectClass OPTIONAL,

subordinates SET OF Name Tree OPTIONAL}

NameType :: = CHOICE {

numericName INTEGER,

pString GraphicString}

When the 'MITSearchResponse' formed by the operation of the program is received from the management information tree (MIT), which is an instance information base, is received by the agent process 21, the agent process 21 responds with the M-ACTION response. The agent process 21 forms the information received in the 'actionReplyInfo' of the 'Action Reply' in the form of 'ANY' and transmits it to the manager process 11 as follows. do.

ActionReply :: = SEQUENCE

{

actionType ActionTypeld,

actionReplyInfo [4] ANY DEFINED BY actionType

}

Thereafter, the manager process 11 stores the information of the management object received from the agent process 21 through the M-ACTION in its own memory area or forms an external file so that the graphical operator interface can use it.

As described above, the present invention applies management object configuration information of an agent by applying a discovery object class, which is a management object having a function of collecting and transmitting management object information of the agent to the manager in sharing management object information between the manager and the agent. Efficient use in managing management object configuration information of manager system by reading with one action, and interworking with manager system of other manufacturers by sharing managed object through standard proposed in recommendation. This is provided.
