How to keep client-server connections on IPIO

摘要

The present invention relates to an Internet Protocol Over ATM (IPOA) communication method, and more particularly, to a client and a server in an IPOA which checks and automatically recovers a connection error between the IPOA client and an ARP server and the connection state. To maintain the connection between the two.;According to the present invention, after the IPOA client periodically sends an ARP request message to the IPOA server, it checks whether or not the response message is received, changes the IPOA inactive mode when there is no response message, and releases the connection between the existing client servers and the new one. After the connection is established, the initialization process is performed to check whether there is an error between the IPOA client and the ARP server and to check the connection status.
