Consider the scenario shown in the figure below. N$=10$ clients and a CDN node $($explained below$)$ are in a local area network with a Gbps $(1,000,000,000)$ path with a $1$ msec RTT between any two hosts in the LAN. The client LAN is connected to another network containing an origin server, netflix.com, via a $1$ Mbps $(1,000,000$ bps$)$ link between routers R$1$ and R$2$ with a $100$ ms RTT delay. All web pages being served by netlix.com are $500$Kbits in size. You can assume that any other messages involved below are very short, and thus have a transmission time of zero, but do experience propagation delays
