1. You have developed a new Transport Layer protocol named NSP (New Segment Protocol). Its header consists of four 1-byte fields: source port, destination port, length, and checksum. The length field specifies the number of bytes in the NSP segment. The checksum is computed using the Internet Checksum standard over 1-byte words. An application has been assigned port number 218, and wants to transmit the following ASCII (1 byte) encoded data: PUPR. The destination process has been assigned port number 235. NSP Segment Structure source port # destination port # length checksum PAYLOAD a. Determine the checksum value. Show all of your work! (8 points) b. Build the NDP segment by entering the bit values in the correct fields of the table provided. The first value has been included. (7 points) |1|1|01|0 1.
