Method and system for detecting failure-causing client with failure handling edge server grouping

Abstract

Provided is a client terminal access control method, and the method includes: allocating a communication process of a first client group comprising a plurality of client terminals to an edge server; when a failure occurs in an operation of the edge server, allocating a communication process of a second client group comprising at least one client terminal belonging to the first client group to a failure-handling edge server; and determining whether a failure occurs in an operation of the failure-handling edge serve.

What is claimed is: 
     
         1 . A client terminal access control method performed by a client terminal access control apparatus, the method comprising:
 allocating a communication process of a first client group comprising a plurality of client terminals to an edge server;   when a failure occurs in an operation of the edge server, allocating a communication process of a second client group comprising at least one client terminal belonging to the first client group to a failure-handling edge server; and   determining whether a failure occurs in an operation of the failure-handling edge serve,   wherein when a failure occurs in the operation of the failure-handling edge server and a number of client terminals allocated to the failure-handling edge server is greater than or equal to a predetermined number, a communication process of a sub client comprising at least one client terminal belonging to a client group allocated to the failure-handling edge server is allocated to a failure-handling edge server, and   wherein when a failure occurs in the operation of the failure-handling edge server and the number of client terminals allocated to the failure-handling edge server is the predetermined number, the predetermined number of client terminals are determined as failure-causing client terminals.   
     
     
         2 . The client terminal access control method of  claim 1 , wherein the predetermined number is 1. 
     
     
         3 . The client terminal access control method of  claim 1 , wherein the communication process of the sub client group is allocated to a failure-handling edge server in which no failure occurs. 
     
     
         4 . A client terminal access control apparatus comprising:
 a communication unit configured to perform data communication with an edge server and a failure-handling edge server; and   a processor configured to
 allocate a communication process of a first client group comprising a plurality of client terminals to an edge server, 
 when a failure occurs in an operation of the edge server, allocate a communication process of a second client group comprising at least one client terminal belonging to the first client group to a failure-handling edge server, 
 determine whether a failure occurs in the operation of the failure-handling edge server, 
 wherein when a failure occurs in the operation of the failure-handling edge server and a number of client terminals allocated to the failure-handling edge server is greater than or equal to a predetermined number, the processor allocates a communication process of a sub client group comprising at least one client terminal belonging to a client group allocated to the failure-handling edge server to a failure-handling edge server, and 
 wherein when a failure occurs in the operation of the failure-handling edge server and the number of client terminals allocated to the failure-handling edge server is the predetermined number, the processor determines the predetermined number of client terminals as failure-causing client terminals. 
   
     
     
         5 . A client terminal access control method performed by a client terminal access control system having an edge server, a failure-handling edge server, and an access control device, the method comprising:
 performing, by the edge server, a communication process of a first client group comprising a plurality of client terminals;   performing, by the failure-handling edge server, a communication process of a second client group comprising at least one client terminal belonging to the first client group when a failure occurs in an operation of the edge server; and   determining, by the access control device, whether a failure occurs in an operation of the failure-handling edge server,   wherein when a failure occurs in the operation of the failure-handling edge server and a number of client terminals allocated to the failure-handling edge server is a predetermined number, a communication process of a sub client group comprising at least one client terminal belonging to a client group allocated to the failure-handling edge server is allocated to a failure-handling edge server, and   wherein when a failure occurs in the operation of the failure-handling edge server and the number of client terminals allocated to the failure-handling edge server is the predetermined number, the predetermined number of client terminals are determined as failure-causing client terminals.   
     
     
         6 . A client terminal access control system comprising:
 an edge server;   a failure-handling edge server; and   an access control device,   wherein the edge server performs a communication process of a first client group comprising a plurality of client terminals,   wherein when a failure occurs in an operation of the edge server, the failure-handling edge server performs a communication process of a second client group comprising at least one client terminal belonging to the first client group,   wherein the access control device determines whether a failure occurs in the operation of the failure-handling edge server,   wherein when a failure occurs in the operation of the failure-handling edge server and a number of client terminals allocated to the failure-handling edge server is a predetermined number, the access control device allocates a communication process of a sub client group comprising at least one client terminal belonging to a client group allocated to the failure-handling edge server to a failure-handling edge server, and   wherein when a failure occurs in the operation of the failure-handling edge server and the number of client terminals allocated to the failure-handling edge server is the predetermined number, the access control device determines the predetermined number of client terminals as failure-causing client terminals.   
     
     
         7 . A computer program stored in a computer-readable recording medium to execute the method of any one of  claims 1 ,  2 ,  3  and  5 . 
     
     
         8 . A computer-readable recording medium storing a computer program to execute the method of any one of  claims 1 ,  2 ,  3  and  5  by a computer.
