Communication between modem and router Ensure devices exchange data for optimal performance
Communication between modem and router Ensure devices exchange data for optimal performance
I'm explaining how routers manage signal distribution while keeping traffic organized across multiple devices.
It maintains a list of MAC addresses paired with their corresponding IP addresses for every device it detects. Each port functions as a direct connection, and the router tracks which IP belongs to which port.
Using only the IP address, the packet arrives with its target destination. The router processes it by removing MAC headers, performing lookups, and re-packeting it with updated source and destination MACs. It sends the modified packet through the port associated with the device's known location. If unknown, it broadcasts across all ports asking for identification. When a matching device replies "Me," it records that information. Based on subsequent steps, the device either handles the packet immediately or passes it to the next hop, which may repeat the decapsulation and lookup process.
