It should be noted that reference numerals and like elements among the drawings are denoted by the same reference numerals and symbols as much as possible even though they are shown in different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a network diagram for providing SLA failure quality according to an embodiment of the present invention.

Referring to Fig. 1, a plurality of Internet subscribers 101 access a high speed national network through a subscriber access router 102. At this time, the subscriber access router 102 connects to the access ATM switch 103 of the ATM backbone network 104. The access ATM switch 103 and the relay ATM switch 105 are connected to an ATM fixed virtual channel (hereinafter, referred to as a 'PVC'). In the connection between the relay ATM switch 105 and the relay fast router 106 of the high-speed Internet backbone network 107, the ATM card of the relay ATM switch 105 and the ATM card in the relay fast router 106 are connected. ATM port is connected. In addition, the relay high-speed router 106 is connected to the backbone network relay router 109 in the other carrier's Internet backbone network 110 via the backbone network relay router 108 in the high-speed Internet backbone network 107. In such a structure, a desired Internet service may be provided to the subscriber 101. The high speed internet backbone network 107 is connected to the SLA system 112 and the failure management system 113 through the relay high speed routers 106 and 111. The ATM backbone network 104 is connected to an ATM network management system (ATM NMS) 115 and the high speed internet backbone network 107 is connected to a high speed internet network management system (high speed internet NMS) 114.

2 is a flowchart of a subscriber information processing process for failure quality in a new subscriber subscription process in an SLA system according to an embodiment of the present invention.

First, the SLA system 112 receives the subscriber's subscription information (step 201). The SLA system 112 then determines whether the received subscription information is a completed subscription (step 202). Completion here refers to the task of accommodating subscribers into the network.

As a result of the determination in step 202, if the received subscription information is not the completion subscription, the reception of the next subscription information is awaited (step 202). However, when the received subscription information is a completed subscription, the SLA system 112 again determines whether the subscription information is a subscription reception for a high speed national network Internet service subscriber (step 203).

If it is determined in step 203 that the received subscription information is not a subscription for a high speed national network Internet service subscriber, the SLA system 112 proceeds to step 201 and waits for reception of the next subscription information (step 203). However, if the received subscription information is for a subscriber to a high speed national network internet service, the SLA system 112 checks whether or not it is completed in the high speed national network internet service network management system (NMS) 114 (step 204).

Subsequently, when the SLA system 112 is actually completed for the subscriber, the SLA system 112 converts the subscriber service agreement ID, the subscriber router IP, the relay router IP, the access ATM switch physical port information, and the relay ATM switch physical port information into one common information. Recognize and save it. Here, the subscriber service contract ID, subscriber router IP, and relay router IP correspond to subscription information. The access ATM switch physical port information and the relay ATM switch physical port information correspond to physical information (facility information).

3 is a flowchart illustrating a failure processing process when failure information is generated for each network in an SLA system according to an exemplary embodiment of the present invention.

Referring to FIG. 3, first, a failure handling process when failure information by network in the SLA system 112 according to an embodiment of the present invention is started by the SLA system 112 receiving failure information (step 301). Subsequently, the SLA system 112 determines whether the received failure information is failure occurrence information. As a result of determining whether the failure occurs, if the received failure information is failure termination information, the failure quality control system operator is notified of the failure status and ends (step 302).

However, when the determination result in step 302 indicates that the received failure information is failure occurrence information, the SLA system 112 again determines whether the failure information relates to an ATM service subscriber (step 303). That is, in the case of the high-speed national network Internet service, since the ATM network is used as the access network, the ATM subscriber and the high-speed national network Internet service subscriber are mixed. Therefore, the SLA system 112 once receives all the failure information generated in the ATM network and determines whether it is an ATM subscriber.

If the failure information in the determination step 303 relates to the ATM subscriber, the failure information is transmitted to the ATM failure management module in the ATM NMS 115, and whether other failure information is received. Check (step 304).

However, if it is determined in step 303 that the failure information does not relate to an ATM subscriber, it is checked whether the failure information is a subscriber of a high speed national network Internet service (step 305). As a result of the determination in step 305, if the failure information is not a subscriber of the high-speed national network Internet service, the failure information is received, so it is checked whether other failure information is received (step 305).

However, in the case where the failure information in the step 305 is related to the high speed national network Internet subscriber, it is checked whether the failure occurrence port information and the connection identifier information are in the received failure information (step 306). Here, in the case of ATM, a plurality of logical ports can be allocated to one physical port, and the subscriber is assigned these physical ports and logical ports. Therefore, the information about the physical port and the logical port corresponds to the connection identifier information.

As a result of checking in step 306, if the two pieces of information, that is, the failure port information and the connection identifier information, exist in the received failure information, it is checked whether there is already generated information for the corresponding subscriber (step 313). . As a result of the check in step 313, if there is already generated information on the corresponding subscriber, the received failure information is received duplicated failure information, thus ending the procedure. Whether the received failure information is duplicate failure information may be determined as follows. That is, by combining the physical port information and the connection delimiter as one key value, if the fault information matches the previously generated fault occurrence information that has not been completed before, the fault information is recognized as a duplicate fault occurrence and only the first fault occurrence information is maintained. However, when there is no previously generated failure information with respect to the failure information, it may be determined that a duplicate failure does not occur.

However, as a result of the check in step 313, if there is no existing generation information for the corresponding subscriber, since the failure occurrence information for the corresponding port of the corresponding subscriber is received for the first time, the failure quality control system 113 fails to the operator. The status is notified and terminated (step 314).

If it is determined in step 306 that none of the faulty port information and connection identifier information is found in the received fault information, the port information in the subscription information is searched for (step 307). 115, request confirmation of port information and connection information (step 308).

The ATM NMS 115 then sends connection identifier information and faulty port information to the SLA system 112 as a return value (step 309).

Thereafter, the SLA system 112 determines whether the port information in the subscription information is identical based on the connection identifier information received from the ATM NMS 115 and the failed port information (step 310).

If it is determined in step 310 that the connection identifier information received from the ATM NMS 115 and the faulty port information and the basic information (port number in the subscription information) do not match, they are returned from the ATM NMS 115 again. The port information is updated from the subscription information (step 311), the connection separator information is added to prevent duplicate failure detection, and then a failure duplication for the corresponding subscriber is checked (step 313).

In addition, if it is determined in step 310 that the connection identifier information received from the ATM NMS 115 and the failure port information and the basic information match, it is checked whether the failure occurrence information for the corresponding subscriber is duplicated (step 313). The failure quality control system 113 operator is then notified of the failure condition and the procedure ends (step 314).

Here, the ATM NMS 115 has all PVC connection interval information, but generates a failure alarm for both endpoints when a specific port failure occurs in the interval. In this case, a failure alarm may be generated for both ends, but only one of both ends may occur, or a failure alarm may occur in duplicate. In particular, the subscription information and the failure occurrence information may be different due to an arbitrary section change of the facility operator. Therefore, as in the above-described embodiment of the present invention, the failure occurrence information must be checked for duplication and physical port information change.

The failure handling method for providing SLA failure quality according to the present invention may be implemented as computer readable codes on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also include those implemented in the form of carrier waves such as transmission over the Internet. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims below, but also by those equivalent to the claims.

According to the present invention as described above, by providing the SLA failure quality for Internet service users using the ATM network of the high-speed national network as an access network, the Internet service provider can provide the failure quality agreed with the customer to the high-speed national network Internet service users There is an advantage.

In addition, according to the present invention by separating the information about the subscribers of the high-speed national network Internet service from the failure information generated in the ATM network for the users of the high-speed national network Internet service users, the efficiency of failure monitoring is improved and the failure quality set for each subscriber is improved. There is an advantage that can be guaranteed.
