TCP – three-way handshake
syn(synchronising), ack(acknowledgement)
2000-byte segment. Server request Seq 6000 as seq 6000 is missing.
After receive seq 6000, acknowledge 10000 so host send seq 12000 next time without sending duplicates.
Size of window is automatically negotiated between device. Which will make faster or slower. Receiver send this whenever they need.
Amount of overhead(amount of header): TCP > UDP
Multiplex
Send multiple protocol at once attaching port number and protocol.
TCP 4-way handshake. Fin(final)
