Recall the two FEC schemes for VoIP described in Section 7.3. Suppose thefirst scheme generates a redundant chunk for every four original chunks.Suppose the second scheme uses a low-bit rate encoding whose transmissionrate is 25 percent of the transmission rate of the nominal stream.a. How much additional bandwidth does each scheme require? How muchplayback delay does each scheme add?b. How do the two schemes perform if the first packet is lost in every groupof five packets? Which scheme will have better audio quality?c. How do the two schemes perform if the first packet is lost in every groupof two packets? Which scheme will have better audio quality?
