Explanation / Answer
Answer 92
**********
TCP with all its sophistication is not suitable for interactive multimedia traffic because we cannot allow retransmission of packets.
Answer 93
**********
WDM
Generally only one light beam with one wavelength is transferred over a pair of fiber. The wavelength multiplexing technology provides the ability to transmit more light beams, each having different wavelengths, using the same optical link.
