Next Header – Indicates either the first extension header (if present) or the protocol in the upper layer PDU (such as TCP, UDP, or ICMPv6). The size of this field is 8 bits. When indicating an upper layer protocol above the Internet layer, the same values used in the IPv4 Protocol field are used here. TCP vs. UDP (What's the Difference?) | CactusVPN Source port – The port UDP uses on your device to send data. Destination port – The port UDP uses to send data to the recipient. Length – The total number of bytes comprising both the header and payload data. Checksum – A sequence of numbers and letters used to detect errors. TCP headers are heavier – anywhere between 20 and 60 bytes. Week 4 - Computer Networking Cs372 with Redfield at Oregon What is the minimum UDP header size? 8 bytes. Put the steps in the most correct order for closing a TCP Connection. Client sends segment with FIN bit set

PC A has a 1500 byte MTU size and 1460 byte MSS size. PC A needs to send 9000 byte of data to PC B. PC B has a 1400 byte MTU(I am not 100%, but I heard MTU size can be changed) size and obviously 1360 byte MSS size. PC A will segment 9000 byte of data into 6 1460 byte and 1 240 byte, then send all How to Find Maximum Size of IP Data Payload that can MTU: Defines the maximum number of bytes for IP packets including IP header, protocol headers such as, TCP or UDP, and data payload.Protocol headers can be combination of different headers. For example: IPSec has TCP or UDP, AH, and ESP headers. MSS: Defines the maximum number of bytes after the protocol headers.In other words, MSS is the maximum size of the data payload.
However, the size of the receiver window of each TCP endpoint is indicated in each TCP header sent from that endpoint, not just during the 3-way handshake. My question is what happen if the receiver's window size(not sure whether window size matters for UDP communication) or MTU size is smaller than the received packet size?
UDP header composition. UDP uses headers when packaging message data to transfer over network connections. UDP headers contain a set of parameters -- called fields-- defined by the technical specifications of the protocol. The User Datagram Protocol header has four fields, each of which is 2 bytes. They are the following:
