WebOct 9, 2015 · 18. UDP does provide a checksum, however. The UDP checksum is only 16 bits. That means a 1 in 65536 chance of a corrupt packet passing the checksum. in UDP over IPv4 the checksum is optional, so a sender could theoretically end up sending a packet without a checksum. The checksum covers the IP/port information as well as the data. WebJul 13, 2012 · Checksum can be calculated by applying cyclic redundancy check (CRC) mechanism over the data that is being communicated. Each block of data that is traveling the communication channel is attached with a CRC code or checksum and when the data block reaches the destination, this check is applied again to generate a checksum value.
