How to Use Iperfer

Configure and Run Iperfer as server and client on each end of the network to be measured.

Client Mode
```
$ java Iperfer -c -h [server hostname] -p [server port] -t [time]
```
- -c indicates this is the Iperfer client which should generate data.
- Server hostname is the hostname or IP address of the Iperfer server which will consume data.
- Server port is the port on which the remote host is waiting to consume data.
- Server port should be in the range 1024 ≤ server port ≤ 65535.
- Time is the duration in seconds for which data should be generated.
- All arguements are needed to be present.
Server Mode
```
$ java Iperfer -s -p [listen port]
```
- -s indicates this is the Iperfer server which should consume data.
- Listen port is the port on which the host is waiting to consume data.
- The port should be in the range 1024 ≤ listen port ≤ 65535.
- All arguements are needed to be present.

Sample Output

Client Mode
```
sent=58629 KB rate=21.253 Mbps
```
Server Mode
```
received=58629 KB rate=20.947 Mbps
