Public Methods

static int	hostnameToIP (char *hostname, char* hostIP) Convert a hostname to an ip address of xxx.xxx.xxx.xxx
static void	ipNumToString (unsigned int ip, char *ipstring) Convert ip address to a string of xxx.xxx.xxx.xxx
static double	getTimeInSecs () Get time in secs with microsecond accuracy
static void	getHostName (char *name, int len) Get the full host name of a local client
static void	expandHostName (char *src, char *newname, int len) If hostname is not fully expanded (ie does not include its domain) then expand it.
unsigned int	getTotalDataSent () Get the total data sent by a connection.
unsigned int	getTotalDataRead () Get total data received by a connection.
double	getInstantReceiveBandwidth () Get total instantaneous incoming bandwidth by a connection.
double	getInstantSendBandwidth () Get total instantaneous outgoing bandwidth by a connection.
double	getAverageReceiveBandwidth () Get average incoming bandwidth by a connection.
double	getAverageSendBandwidth () Get average outgoing bandwidth by a connection.
void	setInstantLatency (double lat) Set the instantaneous latency and also calculate the STALatency and Jitter values automatically
double	getInstantLatency () Retrieve most recent incoming packet's latency.
double	getAverageLatency () Retrieve average incoming latency.
double	getMaxLatency () Retrieve max latency so far.
double	getMinLatency () Retrieve min latency so far.
void	incrementDataSent (unsigned long size) Record amount of data sent.
void	incrementDataRead (unsigned long size) Record amount of data read - and also compute instantaneous, average bandwidths along with the inter message delay values
double	getInstantInterMesgDelay () Get instantaneous inter-message delay (jitter)
double	getMaxInterMesgDelay () Get max inter-message delay (jitter)
double	getMinInterMesgDelay () Get min inter-message delay (jitter)
double	getAverageInterMesgDelay () Get average inter-message delay (jitter)
double	getSTABandwidth () Get the Short Term Average Bandwidth -over a fixed number of packets (defined by BANDWIDTH_BUF_SIZE)
double	getSTALatency () Get the Short Term Average Latency -over a number of packets (defined by LATENCY_BUF_SIZE)
double	getBurstiness () get the burstinesss
double	getJitter () Get the Jitter
unsigned long	getPacketsRead () Return the total number of packets read
unsigned long	getPacketsSent () Return the total number of packets sent
virtual int	getSocketId () Returns the socket id
int	selectSock (void *ptr, int *status, int numSocks, struct timeval *timeout) Returns the status of the sockets being polled
