Abstract

PURPOSE: A remote debugging method using a thread between a network management center and a switch is provided for transmitting a thread-based debugging state to a remote terminal and displaying the debugging state. CONSTITUTION: A relay apparatus(20) generates a debugging thread(23) for a debugging operation in a process of an execution module and periodically checks a connection request input using a TCP/IP protocol. At this time, when there is a connection request using a TCP/IP protocol from a remote terminal(40), a debugging thread(23) of the relay apparatus(20) announces a socket fd(file descript) as a global variable returned in ACCEPT() and shares the threads of the process. An error message and circumference message generated in the function-based thread are transmitted to the remote terminal(40).

Description

Remote debugging using the network management center and the threads of the exchange period {REMOTE DEBUGGING METHOD USING THREAD BETWEEN EXANGE SYSTEMAND NETWORK MANAGEMENT CENTER}

The present invention relates to a method of debugging so as to grasp the state of a corresponding application at a remote location during communication between an exchange system and an operation support system (OSS).

In the exchange system, even when the link between the network management center in charge of the exchange network and the exchange period is lost, the exchange continues to transmit network management data to the network management center, and the status of the application communicating with the remote site is maintained. There was a problem that could not be grasped.

Accordingly, an object of the present invention is to provide a remote debugging method that can determine the application state by using the thread of the application in a remote place where the network can be used during communication between the switch and the network management center to solve the above problems.

In the remote debugging method using the network management center of the present invention and the thread of the exchange period for achieving the above object, the process of detecting the type to be debugged in the debugging thread when the debugging terminal request from the remote terminal, And detecting and transmitting a debugging status for each thread of the detected type to the remote terminal.

1 is a connection diagram between a switch and a network management center according to an embodiment of the present invention;

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Many specific details, such as specific process flows, are set forth in the following description to provide a more general understanding of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a connection diagram between a switch and a network management center according to an embodiment of the present invention.

The relay device 20 is connected between the switch 10 and the network management center 30. The relay device 20 is an extended interface processor (EIP), and collects network management data inside the switch 10. The first thread (thr_CToEX) 21 which communicates with the transmitting processor and manages the link as a whole, and the second thread which performs network management data transmission through the TCP / IP link to the external network management center 30 ( thr_EXToCT) and an error message and situation occurring in the first and second threads 21 and 22 when a connection request is made by the TCP / IP protocol from the remote terminal 40 by being connected to the remote terminal 40. It consists of a debugging thread 23 which sends a message to send.

An operation of remotely debugging a communication state between the relay apparatus and the network management center having such a configuration will be described with reference to FIG. 1.

The relay device 20 generates a debugging thread 23 for debugging in a process in the execution module and periodically monitors an incoming connection request using the TCP / IP protocol. At this time, if there is a connection request from the remote terminal 40 using the TCP / IP protocol, the debugging thread 23 of the relay device 20 sets the socket fd (file descript) returned at ACCPET () to a global variable. Declare and share with threads in the same process. Through this socket fd, an error message and a status message generated in the functional thread are transmitted to the remote terminal 40. That is, the debugging thread 23 monitors whether there is a connection request from the remote terminal 40, and sends a connection response signal to the remote terminal 40 when there is a connection request. Then, the debugging thread 23 analyzes the command from the remote terminal 40 to determine the debugging type (TYPE), and when the first type comes in, it requests a connection to the first thread (thr_CToEX) 21 and the relay device ( 20) and the status message of the section 1 between the network management center 30 to be transmitted to the remote terminal 40. At this time, when the first type is entered from the remote terminal 40, the debugging thread 23 requests the connection to the first thread 21 as the first thread thr_CToEX, and the status message between the relay device 20 and the switch 10 is in the ② section. To transmit to the remote terminal 40. When the third type is input from the remote terminal 40, the debugging thread 23 requests the connection to the second thread (thr_EXToCT) 22, and the status message of the section 3 between the switch 10 and the relay device 20 is received. Transmission to the remote terminal 40. In addition, when the fourth type is input from the remote terminal 40, the debugging thread 23 requests the connection to the second thread 22 as the second thread (thr_EXToCT), and a status message of the section ④ between the switch 10 and the relay device 20. To transmit to the remote terminal 40.

As described above, the present invention has the advantage of detecting the cause of the error by detecting a debugging state at a remote place where the network is possible when an unexpected error occurs in the state of communication between the switch and the network management center.
