Checking A Connection; Auto Cdr Process Flow - Avaya S6200 Administration And Maintenance

Managing Reports

Checking a Connection

The ping feature on the AutoCDR server allows a client to determine actively if a connection is
open and the server running. This message is called REQUEST_PING (cmd=04), and is
padded to the same size as a REQUEST_CDR_FILE message. The server's response to this
message is to send the same message back to the client. Specifically, the server will copy the
request's rfu bytes into the response, so the client will receive whatever it sent. No further action
is taken by the server. Note that the server uses no timeout on this connection and it is not
necessary for a client to send these messages in order to maintain the connection; the ping
feature is provided merely as a means of verifying it.
The format of REQUEST_PING is:
struct request_ping
{
char cmd[2];// "04"
char rfu[11];
};
