Header overhead ?

A typical IEEE 802.3 Ethernet packet structure is illustrated in Figure 19.8, with the terminology explained below.

• Preamble: Uses 64 bits to synchronize with the signal's frequency before transmitting the real data.

• MAC Dest/Src: Records the destination and source MAC addresses of the packet, each with 6 bytes.

• Length: Specifies the length of the IP packet with 2 bytes.

• Frame-check sequence: Contains a 32-bit cyclic redundancy check that enables the detection of corrupted data within the packet.

• Inter-frame gap: After a packet has been sent, transmitters are required to transmit a total of 96 bits of "idle line" state before transmitting the next packet.

• IPv6 header: 40 bytes in total.

• TCP header: 20 bytes in total.

What is the percentage of payload data rate if we are to send a 250-byte packet?
