Overview
- Stream of bytes, In sequence
- Congestion Control (BBR)
- Networking Flow Control Algorithm to stop the overflow at the receiver’s end
- Provides reliable, ordered, and error-checked delivery of a stream of bytes.
Why TCP/IP
IP is a connectionless protocol, which means that each unit of data is individually addressed and routed from the source device to the target device, and the target does not send an acknowledgement back to the source.
That’s where protocols such as TCP come in. TCP is used in conjunction with IP in order to maintain a connection between the sender and the target and to ensure packet order.
