What is the shorted time to transmit a 50 ATM packets at 2.5 Gbps
Hosts A and B are each connected to a switch S via 1-Gbps links as below. The propagation delay on each link is 20 μs. S is a store-and-forward device; it begins retransmitting a received packet 35μs after it has finished receiving it. Calculate the total time required to transmit 10,000 bits from A to B in the following two cases: When all the 10,000 bits are transmitted in a single packet? When the 10,000 bits are transmitted in two...
QUESTION 1 2 points Save Answer You have a device that wants to transmit many packets to a router, which is sometimes busy serving other users. At every second, your device attempts to send a packet. It succeeds with probability 1/5 and the success of any attempt is independent of the success of other attempts. Let N be the number of attempts until the first success. What type of random variable is N? Bernoulli Binomial Geometric O Poisson QUESTION 2...
2. The time intervals between successive packets arriving at a network router interface is expo nentially distributed with a mean of 10ms. There are hundreds of different types of packets, however the two dominant types are TCP and UDP. Studies show that approximately 20% of traffic is UDP and 80% of traffic is TCP. Find the probability that the time interval between two successive packets (of either type) is less than 2ms Find a time interval t such that we...
(a) A data link with a 1 Gigabits/sec capacity is used to transmit packets made up of 1400 bytes of data and 100 bytes of protocol control information. Each packet is acknowledged by a short frame of size 150 bytes. The propagation speed in the transmission medium is 200,000 km/sec. Consider the buffering and processing time in the nodes to be negligible. A node A communicates with a node B, with a distance between nodes A and B of 16...
Assume a sender's network stack sends packets with the time-to-live field set at 128 by default. While traversing the network, packets go through three routers and two switches before arriving at the receiver. What is the TTL field set to when the packets arrive at the receiver/ 0125 0123 0 131 133

To what Kelvin temperature would I have to reduce 3 liters of helium initally at 273 K and 1 atmosphere to reduce its volume to 1 liter? 3. If I have 2.0 moles of helium in a balloon at 300 K and 0.91 atm, what is its inital...
The volume of a gas is 20.3 mL at 50◦C and 0.871 atm. What will the volume be at 10◦C and 0.994 atm? Answer in units of mL.
A sample of 5.0 L of CO2 gas was collected at 25⁰C and 2.5 atm. At what temperature would the gas have to be stored if the flash is 10.0 L and the pressure is 0.975 atm?
