What is the purpose of the traceroute program?
What is the purpose of the traceroute program?
- To measure the bandwidth of the network connection
- To establish a secure connection between sender and receiver
- To send packets from the destination to the source
- To provide delay measurements from source to router along the Internet path towards the destination (correct)

- Two probes
What does a lost probe in a traceroute typically indicate?
What does a lost probe in a traceroute typically indicate?
- Network security breach
- Router failure
- Packet loss (correct)
- Internet congestion

Throughput is the rate at which bits are transferred between sender and receiver over a long period of time.
Throughput is the rate at which bits are transferred between sender and receiver over a long period of time.
Rs < Rc implies that the sender's capacity is greater than the receiver's capacity.
Rs < Rc implies that the sender's capacity is greater than the receiver's capacity.
Packet loss can occur if a packet arrives at a full queue preceding a link.
Packet loss can occur if a packet arrives at a full queue preceding a link.
