How Does TCP- Tahoe, Reno Work?

The internet is a busy highway where data travels in small packages called packets. TCP Tahoe and Reno are two different driving rules that help these packets reach their destination safely.

Imagine you are sending a box of LEGO bricks to a friend. You put a note inside saying, "I am sending 100 bricks." If your friend doesn’t confirm he got them, you send more and more, hoping they arrive.

TCP Tahoe is like a driver who panics easily. If one brick goes missing, Tahoe assumes the whole road is blocked. It stops sending everything, waits a long time, and starts over from zero. It is safe but can be slow.

TCP Reno is smarter. It acts like a cautious but efficient driver. If a brick is missing, Reno assumes there is just a small traffic jam. It slows down the speed gently instead of stopping completely. It tries to share the road fairly with other drivers so no one hogs the bandwidth.

Think of Tahoe as slamming on the brakes at every speed bump. Think of Reno as easing off the gas pedal just a little bit. Both want your LEGO bricks to arrive, but Reno handles the bumps of the internet highway much more smoothly. This keeps your video calls clear and your games lag-free.
