2. The access link from a home computer to the Internet over a telephone connection with a modem of 56kbps limits the amount of data that can be sent and received by the computer. (a) Let us assume that low-quality video is streamed from a server on the Internet to the home computer. Does it make sense to model the Internet access link of the home computer with the model of a "leaky bucket" or a "token bucket" ? (see Annex for diagrams representing these models) - What would be the values of the characteristic parameters of these bucket models (bucket size and leaking rate for the leaky bucket, or token arrival rate and bucket size for the token bucket)? - Please discuss whether the leaky bucket and/or the token bucket model applies, and what the appropriate parameters would be. (b) Compare the application of streamed video with a file transfer application. Would the bucket model(s) also apply to the case that a file is transfered from a remote server to the home computer ? - Please discuss. 2.
