a)

Program Plan Intro

Streaming stored audio/video:

  • It is an application where the medium of transmission is video that is pre-recorded.
  • The video could be a movie or sport show that is already recorded.
  • The video are requested are based on the users request, the videos are stored on the servers and based on the request made by the user the videos can be viewed.
  • The companies that stream the contents that prerecorded are YouTube, Hulu and Netflix.

Consider two hosts S and R connected directly by a link. A link has a transmission speed of 107 bits/sec. It uses data packets of size 400 bytes. Data needed to transmitted is 400 bytes. Length of the link is 600 km and the propagation speed are 3 × 108 meter per second. T is the transmission delay and P is the propagation delay. The propagation delay in millisecond and transmission delay in microsecond respectively are
How long does it take a packet of length 1,000 bytes to propagate over a link of distance 2,500 km, propagation speed 25.125 m/s, and transmission rate 2 Mbps? More generally, how long does it take a packet of length L to propagate over a link of distance d, propagation speed s, and transmission rate R bps? Does this delay depend on packet length? Does this delay depend on transmission rate?
Let a denote the rate of packets arriving at a link in packets/sec, and let μ denote the link’s transmission rate in packets/sec. Based on the formula for the total delay (i.e., the queuing delay plus the transmission delay) derived in the previous problem, derive a formula for the total delay in terms of a and μ.
