Traffic generators:

Traffic generators are used to create and send customized packets. Customization includes changing the contents of the headers, SETTING the size, speed, number of packets, generating different streams of packets etc. IxNetwork, Spirent Smart Bits, Ostinato, Scapy, Hping, IPerf etc are some of the traffic generators used in the protocol testing INDUSTRY.

Capturing tools:

Capturing tools are used to capture and analyze the packets send/received in the interfaces. Tools LIKE Wire shark, Tshark, Scapy, TcpDump can be used to check the header structure, size the contents of the captured packets.

Simulators:

Simulators are used to create virtual routers/switches to setup topologies with many devices which will be difficult to setup if we are USING physical devices. IxNetwork, Spirent Test Center etc can be used to SIMULATE virtual device.
