Consider the following illustration of a proxy server, Client Client Client Transmission rate R Proxy Cache Server Transmission rate: R Internet Web Server Assume that HTTP messages containing objects are 1 KB and that HTTP messages not containing objects can be ignored as they do not produce a significant delay. Also, assume the transmission rate of the proxy server, Rp = 25 Mb/s, and the transmission rate of the webserver is Rs = 14 Mb/s. If clients transmit on average 1500 HTTP requests per second and the proxy server has a cache hit rate of 70%, what is the traffic intensity at the link connecting the proxy server to the Internet? (provide your answer to 2 significant figures)
