overhead becomes less important as the payload size increases. The packet size was increased to

a maximum of 1480 bytes, the size of the Ethernet frame payload. Packets that are larger than

this are dropped by the AN-50. In order to use larger packets, such as MPLS packets, on a

network with the AN-50 they need to be fragmented before being sent to the AN-50.

5.2 Received Signal Level Effects: Several tests were run where the received power level was

varied and the throughput was measured. These tests were taken with both IP traffic and Iperf as

Fig. 5.1 Throughput Vs. Packet Size. The effects of packet size are minimal once the payload size

dominates the total packet size.
