Program Plan Intro

Given Information:

For distributing a file,

F= 15 Gbits = 15 * 1024 Mbits

The upload rate of server (us = 30 Mbps)

Download rate (di) = 2 Mbps

The formula for calculating the minimum distribution time for client-server distribution is:

Dcs= max { NF/us, F/dmin}

The formula for calculating the minimum distribution time for P2P distribution is:

Dp2p= max{F/us,F/dmin,NF/(us+i=1Nui)}

Suppose we have a web page which contains 10 objects including: a html main file, 8 jpg image, and a .mp3 background music. For simplicity, assume each of the 10 objects has a size of 4 Kbits and that each object can be completely transferred in one TCP packet. Furthermore, assume the round-trip time between the server and client is RTT= 250 ms, and the download rate is 1 Mbps. What will be the time it takes to complete transferring the web page running in the non-persistent mode? Total delay = ms
Consider distributing a file of F = 20 Gbits to N = 100 peers. The server has an upload rate of us = 40Mbps, and each peer has a download rate of di = 5 Mbps and an upload rate of ui = 500 Kbps. i) Estimate the distribution time in a client-server architecture. ii) Estimate the distribution time in a peer-to-peer architecture.
Copy from chegg == Report! A communication line capable of transmitting at a rate of 50 Kbits/secwill be used to accommodate 10 sessions each generating Poisson traffic at a rate 150 packets/min.Packet length are exponentially distributed with mean 1000 bits. For each session, find the averagenumber of packets in queue, the average number in the system, and the average delay per packetwhen the line is allocated to the sessions by using: i) 10 equal-capacity time-division multiplexed channels;ii) statistical multiplexing
