![]() ![]() So, this Pseudo Header is not transported across the network, rather the actual IP header which is formed in Network Layer is transported. And the checksum is calculated by using the usual checksum method. So, the total size of the pseudo header(12 Bytes) = IP of the Source (32 bits) + IP of the Destination (32 bits) +TCP/UDP segment Length(16 bit) + Protocol(8 bits) + Fixed 8 bitsĪn important concept should be noted that this Pseudo header is created in the Transport layer for calculation and after the calculation is done the Pseudo header is discarded. ![]() Protocol (stating the type of the protocol used).Thus a part of the IP header is taken into account which don’t change as the IP packet moves in the network. We directly don’t use the IP header because in IP header there are many which would be continuously changing when then packets move along the network. The pseudo-header is not an IP header rather it is a part of the IP header. Network Devices (Hub, Repeater, Bridge, Switch, Router, Gateways and Brouter).Domain Name System (DNS) in Application Layer.Internet Protocol version 6 (IPv6) Header.Internet Control Message Protocol (ICMP).Program to remotely Power On a PC over the internet using the Wake-on-LAN protocol.TCP/UDP checksums cover the entire segment. TCP/UDP checksum is a end-to-end checksum meaning it is computed by the sender and verified by the receiver. Finding cabs nearby using Great Circle Distance formula Ethernet checksum is a hop to hop checksum - meaning that it is recomputed everytime the Ethernet header fields change.ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.It is computed so that re-computing the sum across the entire IP header (including the checksum. DevOps Engineering - Planning to Production The checksum algorithm adds the header bytes 16 bits at a time.Python Backend Development with Django(Live).Android App Development with Kotlin(Live). ![]()
