Caculate the throughput, in packet/sec, for a link that uses 400-bit long packets and has a BER of 1 bit in 1,000 bits. Assume the packet rate is 500 packet/sec, and that the link has no packet loss. Report only the integer part of your answer. Caculate the throughput, in packet/sec, for a link that uses 400-bit long packets and has a BER of 1 bit in 1,000 bits.
