void calculateJitter(double lat)

void calculateBurstiness(double bw)

void setTimeOut(int t)

Set timeout period when performing read() or write() operations

Parameters:

t - Time out period in seconds. Set to CAVERNnet_tcpClient_c::NO_TIME_OUT to set no time out period.

int init(int port)

Open the server on a port. Typically after this call you sit in a loop and call checkForNewConnections to wait for incoming connections.

Returns:

FAILED if failed, OK if success

CAVERNnet_tcpClient_c* checkForNewConnections()

Check to see if there is a request from clients for connection. If yes then return a CAVERNnet_tcpClient_c object which you can then use to talk to the client.
