2. two hosts a and b are communicating through a tcp connection. the maximum segment size (mss) has been negotiated to be 1kbyte, and the size of the receiver window of b is 50 kbytes. the network capacity is 1 mbps, the round-trip time is 20ms, and the initial threshold of the slow start algorithm is set to 64 kbytes. an expiration timer of 1s is engaged at the beginning of each transmission burst. a. if the 4th transmission round is completely lost, how long does it take to reach a congestion window of "maximum size" after the loss? clearly illustrate your work (by just giving me a number will earn you no points) b. now assume that the network has a capacity of 10 mbps. find the throughput of the session and the maximum efficiency (in the b direction)

Consider the simple 3-station assembly line illustrated below, where the 2 machines at station 1 are parallel, i.e., the product only needs to go through one of the 2 machines before proceeding to station 2.what is the throughput time of this process?

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e.g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
