1 is a structural diagram of a service management system and a management gateway system for each function in an integrated network environment to which the present invention is applied.

Management commands from the service management system 101 are communicated to the associated server processes 103 through 106 through the Ethernet board of the management gateway system 102 through a standard interface called CORBA.

The application program interface adapter 109, which performs a message change process for changing the management command into an application program interface command provided by the exchange, performs an exchange processing procedure based on the component identifier shown in FIG. Perform the conversion procedure with a unique management command. In addition, the status information or fault information on the component generated from the exchange is also converted by the corresponding component identifier conversion method and then transmitted to the service management system 101.

The management instruction conversion procedure is dependent on the exchange constituting the network component, and in the present invention, it is intended for the passport exchange and DPN-100 exchange made by "Northern Telecom" which occupy most of the data network.

When the service management command transmitted from the service management system 101 is successfully converted by the application program interface converter (i.e., the adapter) 109 via the servers 103 to 106 in the management gateway, the application program interface converter. 109 transmits the converted application program interface command to the application program interface command provider in the exchange through the Ethernet board and receives the result of the command.

If the result of the command is successful, the servers 103 to 106 in the management gateway add or change attribute values of components existing in the component management database table 107.

The service management system 101 and the management gateway system 102 have a hierarchical structure, and the service management system 101 manages management commands and failure reports on services managed by the service management system 101.

The service management system 101 generates a service management command and transmits the service management command to the management gateway system 102 that is physically or logically divided and transmits the management command to the corresponding exchange.

The service management system 101 and the management gateway system 102 may be implemented as a database system 107 for storing the mutually open interface and the component management data on the workstation, and the management gateway system 102 is the mutually open interface. It analyzes the delivered service management command and delivers it to the application program interface converter 109. The application program interface converter 109 converts the delivered message into an internal management command form for the corresponding exchange.

The command conversion method corresponding to the present invention is the content performed in the management gateway system 102, so that the exchange can efficiently process the command of the service management system 101.

As shown in the figure, the management gateway system 102 is divided by function for the service management system 101 corresponding to the category of the managed service. That is, the configuration management gateway server 103 in charge of the configuration management of the components, the connection management gateway server 104 in charge of the management of connection management using the components, failure information transmitted from the exchange to the object of the component The fault management gateway server 105 converts and transmits the component identifiers to the element identifiers, and the fault management gateway server 106 that tests the corresponding component from the fault reception or the fault information generated by the user and handles the fault. .

Change or failure occurrence information, performance related information, etc. for the corresponding configuration information are stored in the database 107 for each component or service to increase the persistence of the related information.

2 is a structural diagram of an embodiment of a component identifier for uniquely specifying a management component in the management system 101 and the management gateway system 102 applied to the present invention.

Before describing FIG. 2, the management components managed by the management system 101 and the management gateway system 102 will be described.

Currently, various types of exchanges provide various kinds of services in the data network, and in order to collectively manage these various kinds of nodes from the service point of view, an abstracted information model is required, and such an information model, that is, the management system 101. The management component information managed by the management gateway system 102 is composed of a node, a link, a processing element (PE), a peripheral device interface (PI), a port, and the like.

A node element represents a node operating in a network, and in the conventional data network, there is a passport exchange system for a backbone node and a DPN-100 exchange system for an access node.

The link component (link) represents a link connecting nodes, and the types of links include FRNNI, UTP, X.75, DPN Gateway, Unacked, and ATM according to the installed interface and protocol.

Processing Element (PE) refers to a processing device on which software is executed to provide specific services (Frame Relay, ATM, X.25, etc.).

The Peripheral Interface Component (PI) does not exist in the Passport Switch, and in the case of the DPN-100 system, it represents a peripheral interface that provides an interface with external equipment.

The port component represents the physical interface through which data is actually transmitted and received.In the case of the DPN-100, the number of ports supported by one card and the transmission speed of the ports are determined by the type of peripheral interface (PI). In the case of Passport, the number of ports and the transmission speed are determined by the Card Type.

Hereinafter, FIG. 2 illustrating a structure of a component identifier for uniquely specifying a management component in the management system 101 and the management gateway system 102 will be described.

The management component divides the passport and the resources for the DPN-100 exchange physically and logically and defines them in a controllable unit, and performs resource management by a system management command transmitted from the service management system 101, which is a management entity. It must be able to do this, and it is divided and defined into units that can be executed by the application program interface commands of the exchange.

The management component contains an object identifier (OID) and an object attribute value for an object, and its contents are stored in a database.

Here, the attribute value of the component is a list of representative values representing the state of the object, and generates and manages the component identifier in the structure proposed by the present invention to specify the component uniquely in the entire network.

The component identifier has a hierarchical structure as shown in the figure and has the following meaning.

The frame relay network (frNetwork: frame relay network) 201 represents a specific network among various networks that the service management system 101 should manage. The network of " 201 " may be a network other than a frame relay network (frNetwork).

Hereinafter, a frame relay network for a data network will be described. In addition, there may be ATM networks, IP networks, etc., which have different starting points. Here, the frame relay network (frNetwork) has a specific integer value 3 as a starting point to distinguish it from other networks.

A node (NODE) 202 is a management component representing a node operating in a network, which is located under a frame relay network and has a specific integer value to distinguish it from different nodes. For management efficiency, it has 1 as a starting point and an integer value sequentially increasing.

A link LINK 203 is a management component representing a link connecting nodes. The link 203 is located below a frame relay network and has a specific integer value to distinguish it from different links. For management efficiency, it has 1 as a starting point and an integer value sequentially increasing.

The processing element (PE) 204 is a management component representing a processing device on which software for providing a specific service is executed. The processing element (PE) 204 is located under a node (NODE) component to distinguish it from different processing elements (PEs). It has a specific integer value. For management efficiency, it has 1 as a starting point and an integer value sequentially increasing.

The port 205 is a management component representing a physical interface through which data is actually transmitted and received. The port 205 is located under a node node and has a specific integer value to distinguish it from different ports. For management efficiency, it has 1 as a starting point and an integer value sequentially increasing.

Peripheral interface (PI) 206 is a management component representing a peripheral interface that provides an interface with external equipment and is located below the processing element (PE) component to distinguish it from different peripheral interface (PI). In order to have a certain integer value. For management efficiency, it has 1 as a starting point and an integer value sequentially increasing.

3 is an explanatory diagram of a naming value for a management component applied to the present invention, and shows an example of the configuration of a component identifier for a management component having a structure as shown in FIG.

Taking a frame relay network as an example, the network is represented by one integer, such as "3", the link is "3.a", the node is "3.x", the processing element (PE) is "3.xy", and the peripherals. The interface (PI) is represented by "3.xyz" and the port by "3.xp".

Where x is the exchange, y is the processing element of the x exchange, z is the peripheral interface of the y processing element of the x exchange. And, p is a port of the x switch and includes information about itself, the processing element to which it belongs, and the peripheral interface.

4 is a diagram illustrating an embodiment of a port component according to the present invention.

The port component represents the physical interface through which data is actually transmitted and received, and is located below the node component and has a specific integer value to distinguish it from different ports. In case of an exchange called DPN-100 The number of ports supported by a card and the transmission speed of a port are determined by the type of peripheral interface (PI) .In the case of an exchange called Passport, the number of ports is determined according to the card type. The transmission rate is determined.

For example, an element identifier (OID) of "3.2.M" indicates the Mth port of frame 2 switch. At this time, the information "Class Type = port of the component identifier" is provided together.

However, since all ports are resources belonging to a specific node as well as a specific board in the node, information on the component identifier (OID) should be provided. That is, in case of DPN exchange, processing element (PE) and peripheral interface (PI) information to which a port belongs is required. In the case of Passport, a local processor (LP) (or card number) to which a port belongs Additional information on is required.

Therefore, in the case of a field for a port number, as shown in the figure, a 16-bit field is divided to store processing element (PE) number, peripheral interface (PI) number, and port number information. That is, the port number field includes not only the corresponding port number but also number information on the processing element (PE) and the peripheral interface (PI) to which the port belongs.

In particular, in the case of a Passport system, the processing element PE corresponds to the local processor LP, and the peripheral interface PI field is filled with a value of "0". The processing element (PE) number and the local processor (LP) number are unique values at the exchange, and the peripheral interface (PI) is also unique at the exchange. The port number has a unique value at a particular peripheral interface (PI).

5A to 5C are flowcharts illustrating an example of a method of converting a management command of a service management system into an exchange command in an integrated network environment according to an embodiment of the present invention. Indicates the process of conversion.

Existing data exchanges have a command structure such as "Exchange Name + PE Number + PI Number + PORT Number" (for example, TMP00 PE / X PI / Y PORT / Z (where X, Y, Z are integers)). According to the present invention, the component identifier from the service management system can be converted into a corresponding management command structure.

The exchange name refers to the exchange as a single value for each exchange, and the processing element (PE) number is the only value within the exchange that indicates the value of a particular processing unit, and the peripheral interface (PI) number The only value present in the exchange represents the value of the peripheral interface, and the port number has a unique value within the peripheral interface (PI).

As shown in the figure, a command conversion procedure for each class type is as follows.

It is determined whether the component identifier (OID) value received from the service management system starts with 3 (501). If the component identifier (OID) value does not start with 3, it is not a component for the corresponding management gateway system. If the task is terminated, and if a component identifier (OID) value is received for a component that starts with 3, each class type is checked (502, 507, 514, 521, 528). Handle as follows:

Basically, when receiving the component identifier value, it receives the information about the class type and the management information for the component.

If the result of the check is that the class type is a node (NODE) (502), i.e., if the receive command from the service management system is for a node (NODE), then the component identifier (OID) and module name for that node, and the node Stores the current state (e.g., failure) in the database table called the node (NODE) table (503), and the module name (at the exchange) upon receipt of commands for management components other than Name of the command format to be used) (504).

After generating the command with the received module name and executing the command (505), receiving the result of the value performed by the command, converting it to the result of the component identifier (OID) and returning it to the service management system. (506).

As a result of the check, if the class type is LINK (507), that is, if the reception command from the service management system is for the link (LINK), the component identifier (OID) information for the two nodes connected to the link and The message received from the service management system including other link configuration information for the link and the current state of the link are stored in a database table called a link table (508).

In order to construct a command for the link, the node having the component identifier (OID) of the node for which the link is configured is searched (509), and the module name of the node is found (510) by searching the node (NODE) table that is already configured. That is, the node table is searched and the component identifier (OID) of the link is converted into the module name.

After generating the command with the converted module name (511), executing the command for this (512), and receives the result of the value of performing the command and converts it to the result value for the component identifier (OID) Return to the service management system (513).

As a result of the check, if the class type is the processing element (PE) (514), that is, if the reception command from the service management system is for the processing element (PE), the component identifier (OID) information for the processing element (PE). And a message received from the service management system including other processing element (PE) configuration information, and a current state of the processing element (PE) in the processing element (PE) table (515).

In order to construct a command for the processing element (PE), the module name for the node in which the processing element (PE) is configured must be found. This is performed by searching the already configured node (NODE) table (516) to obtain the module name of the node. Find (517). That is, the node table is searched and the component identifier (OID) of the node is converted into the module name.

Generate the command with the converted module name (518), execute the command for it (519), receive the result of performing the command, and convert it to the result value for the component identifier (OID). Return to the service management system (520).

For example, if the received component identifier (OID) value of the processing element (PE) is 3.1.2, the meaning of the corresponding component identifier (OID) value means the meaning of "data network.node value.PE value". As such, the component identifier for the node is 3.1 and represents the second processing element (PE) configured in this node.

As a result of the check, if the class type is the peripheral interface (PI) (521), that is, if the received command from the service management system is for the peripheral interface (PI), OID information about the peripheral interface (PI) and A message received from the service management system including other peripheral interface (PI) configuration information and a current state of the peripheral interface (PI) are stored in the peripheral interface (PI) table (522).

In order to configure the commands for the Peripheral Interface (PI), you need to find the module name for the node on which the Peripheral Interface (PI) is configured, which searches the already configured Node (NODE) table (523) for the module name of the node. (524). That is, the node table is searched and the component identifier (OID) for the node is converted into a module name (524).

After generating the command with the converted module name (525), executing the command (526), and receiving the result of performing the command, and converting it into the result value for the component identifier (OID) Return to the service management system (527).

For example, if the component identifier (OID) value of the received peripheral interface (PI) is "3.1.2.4", the meaning of the component identifier (OID) value is "data network. Node value. PE.PI." Value ", the component identifier for the node is" 3.1 "and represents the fourth peripheral interface (PI) configured in the second processing element (PE) configured in this node.

If the class type is PORT, that is, if a receive command from the service management system is for a port (528), the component identifier (OID) information for the corresponding port (PORT) and The message received from the service management system including the other port configuration information and the current state of the corresponding port are stored in the port table (529).

In order to configure the command for the port, the module name for the node to which the port is configured must be found, which searches the already configured node (NODE) table (530) to find the module name of the node ( 531).

Create a command with the corresponding module name (532), execute the command for it (533), receive the result of the value of the command and convert it into the result value for the component identifier (OID) to manage the service. Return to the system (534).

For example, when the component identifier (OID) value of the received port (PORT) is "3.1.z", the meaning of the component identifier (OID) value means "data network. Node value. Port value". The port information corresponding to 2 bytes includes processing element (PE) information and peripheral interface (PI) information, as shown in FIG. 4. The method of the present invention as described above is implemented as a program. Can be stored in a readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited by the drawings.

The present invention as described above, the management gateway system for the data network has an open structure with the service management system and delivers the appropriate management message to the packet, frame relay switch that is the data network (HiNET-P / F network) operation of the switching system And the effect of mutually opening management.

In addition, the present invention, by receiving a management command from the service manager, by analyzing and processing the command format and command parameters provided by the exchange, and by configuring and using an object identifier that can efficiently specify the management component, There is an effect that the integrated network management at the service level which does not depend on the exchange is possible.
