The phenomenon of Packet switching in Network Infrastructure
Packet switching is a method of transmitting data over a network by breaking it into small packets, routing each packet independently through the network, and reassembling the packets at the destination. How it works: 1. Data is divided into small packets, typically with a maximum size (e.g., 1500 bytes). 2. Each packet is given a header containing source and destination addresses, packet sequence number, and other control information. 3. Packets are transmitted over the network, potentially taking different routes. 4. Routers examine packet headers and forward them to the next hop on the path to the destination. 5. Packets may pass through multiple routers before reaching their destination. 6. The receiving device reassembles the packets in the correct order using the sequence numbers. 7. The original data is reconstructed from the packets. Packet switching allows for: - Efficient use of network resources - Flexibility and scalability - Error detection and correction - Multiplexing (m
