EE 030 Chapter Notes - Chapter 3: Nmap, Routing Information Protocol, Piggy Bank
Document Summary
A transport-layer protocol provides logical communication between processes running on different hosts a network-layer protocol provides logical communication between hosts Tcp uses 3-way handshake. (http uses tcp protocol). the 3 way handshake involves syn,synack, The port numbers which are different for tcp and udp . The complete process of end to end transmission using the mac adderss: The addresses given to the packet is as follows: Send is used to just queue the data, and it is sent accordingly. Push this is related to the host side, it assures faster sending of data, sequence is not considered. Urgent assures the faster delivery of the data at the other end. it is sent in the sequence. Mss (maximum segment size ) is decided by the mtu(maximum transmission unit) it decides the longest size of data packet. Udp uses only the port numbers and ,source port is optional in some cases. Finer application-level control over what data is sent, and when.
