摘要:IPV6 is a new technology that has been developing as a replacement for existing Internet protocol, IPV4. IPV6 was designed with same additional features to the IPV4. In order to meet the requirement of fast growing internet, we must switch from IPV4 to IPV6. IPV6 is a datagram protocol same as IPV4 having 128 bit addresses instead of 32 bit in IPV4. An IPV6 packet transmitted through the internet has to pass through many routers along the network. Therefore chances of occurrence of error increases. So error detection/ correction method is to be utilized for the data. CRC is one of the most popular error detection mechanism. Here CRC is used to generate a checksum over the modified field at transmission nodes instead of calculating CRC over the whole frame. In the modified it is 1 byte hop limit only, so there is no need to calculate CRC for the whole frame in intermediate nodes. By calculating CRC only for the modified field of a frame helps to increase the processing time at the sender, receiver and also the overall processing time of an IPV6 packet.
