Consider that a host receives an Ethernet frame that contains an IP datagram. The Ethernet frame format is shown as the following figure 8 bytes 6 bytes 6 bytes 2 46-1500 bytes 4 bytes Preamble/ Destination Source SFD address address User data FCS and the IP datagram format is shown as the following figure -Header 31 0 4 8 16 19 24 Version Header Length Tos Total length identifier Flags Fragment offset TTL Protocol Header checksum Answer the following questions: Source IP address Destination IP address Options (variable length) Data 1) The received Ethernet frame has the following Ethernet frame header fields shown as a hexadecimal stream: AA AA AA AA AA AA AA AB E0 40 07 BA 8E E7 84 3A 4B CB A1 B8 08 00. What are the source and destination MAC addresses (6-byte hexadecimal number) of the Ethernet frame? (2 marks) 2) The received Ethernet frame contains the IP datagram with the following IP header fields shown as a hexadecimal stream: 45 00 00 34 51 A9 40 00 80 06 09 33 C0 A8 03 E8 8C CE 4E 89. a) What is the IP version of the IP datagram? (1 mark) b) What are the total bytes of the IP datagram? (1 mark) c) What is the source and destination IP addresses (in the dotted decimal format) of the IP datagram? (4 marks) d) What is the checksum value of the IP datagram? (1 mark) e) What is the TTL value of the IP datagram?
