A SONET STS-1 SPE is mapped into an STS-1 line. An STS-1 SPE frame consists of 87 columns of 9 bytes, or altogether 783 bytes. There are always 8,000 frames per second. The SPE clock is slower than the line clock by a factor of 5 x 10-7 .On average, we expect to find one pointer adjustment for how many SONET frames?

Describe the working of recursive and iterative queries in DNS. Use figures for the description. A file of F = 3 x 105 bits is distributed to N peers. The server has an upload rate of us = 1 x 105 bps. Each peer has a download rate of di = 1 x 105 bps and an upload rate of u = 30,000 bps. For N = 1 to 10, and for both client-server and P2P architectures, plot a single graph with minimum distribution time on the y-axis and N on the x-axis. Use a table to show all the values for N = 1 to 10 and use the values to plot the graph. Clearly show the calculation only for N = 1, 2, and 3. Explain at least one P2P application (BitTorrent or DHT) in detail.

In this case there will be structural hazard every time a program needs to fetch an instruction during the same cycle in which another instruction access the data. How many stall cycles are introduced in the code due to structural hazards?-- Ans:
