Problem

1. Why does the sequencer need a history buffer?

2. Two algorithms for broadcasting in Amoeba were presented in the text. In method 1, the sender sends a point-to-point message to the sequencer, which then broadcasts it. In method 2, the sender does the broadcast, with the sequencer then broadcasting a small acknowledgement packet. Consider a 10-Mbps network on which processing a packet-arrived interrupt lakes 500 microsec, independent of the packet size. If all data packets are 1K bytes, and acknowledgement packets are 100 bytes, how much bandwidth and how much CPU time are consumed per 1000 broadcasts by the two methods?
