Sending and Observing TCP Segment , IP Datagram , ICMP Datagram , UDP Datagram , Ethernet Frame. 2. Monitor Router Forward Package and Browse Package. 3. Manually Setting Up Routing Table ( Programmable Router). 4. Provides an inside of TCP/IP protocol stack at layers 2 through 4 normally hidden in operating systems. 5. Monitors network traffic in passive mode. Benefits for Learners 1. Fills the need for an easy-to-use networking tool. 2. Provides hands-on experience. 3. Experiments in a real network rather than with computer simulations. 4. Tunes the parameters controlling TCP/IP behavior without digging into operating system kernels. Benefits for Educators 1. Save your time & money. 2. Provides a cost-effective protocol analyzer. 3. Provides experiments for materials that were normally taught in theory. 4. Obviates the needs of the difficult task of modifying operating system internals.
