Consider a web page whose base file is of size S1 = 10 KB. Assume that the web page consists of N = 20 inline objects each of size S2 = 100 KB. Assume that the round-trip time to the web server is T = 100 ms and the bottleneck capacity is C = 10 Mbps. Ignore any packetization delays and header overhead.

a. Assuming non-persistent HTTP is used with a single TCP connection, how long does it take to download the web page?

b. Assuming non-persistent HTTP is used with 4 parallel TCP connections, how long does it take to download the web page?

c. Assuming pipelined, persistent HTTP is used, how long does it take to download the web page? Pipelined means requests for multiple objects can be sent back-to-back on the same connection.

d. Assuming non-pipelined, persistent HTTP with 2 parallel TCP connections is used, how long does it take to download the web page? Assume that the 2 parallel connections equally share the total available bandwidth C.
