Question

In your own words, describe what happens at every step of our network model, when a node on one network establishes a TCP connection with a node on another network. You can assume that the two networks are both connected to the same router.

Answer 1

When a node on one network establishes a TCP connection with a node on another network, several steps are involved in the network model, including packet transmission and routing through routers.

Step-by-step explanation:

When a node on one network establishes a TCP connection with a node on another network, several steps are involved in the network model.

1. The node initiates a communication request by sending a TCP packet to the destination node's IP address.
2. The TCP packet travels through the local network to the router.
3. The router examines the destination IP address and determines the next hop towards the destination network.
4. The packet is forwarded to the next hop, which could be another router or the destination network.
5. This process continues until the packet reaches the destination node on the other network.
6. Once the packet arrives at the destination node, a TCP connection is established between the two nodes, allowing data transfer.

Throughout this process, the TCP protocol ensures reliable and error-free communication between the nodes, handling issues such as data segmentation, acknowledgment, and congestion control.
