QUESTION 18 Code an Express route that Accepts all paths Accepts all HTTP request methods With a callback that does not generate a response message but passes control to subsequent routes
Suppose two TCP connections share a path through a router R. The router's queue size is six segments; each connection has a stable congestion window of three segments. No congestion control is used by these connections. A third TCP connection now is attempted, also through R. The third connection does not use congestion control either. Describe a scenario in which, for at least a while, the third connection gets none of the available bandwidth. and the first two connections proceed with 50% each. Does it matter if the third connection uses slow start? How does full congestion avoidance on the part of the first two connections help solve this? 10:33 am Type a message Dorcon 1 tahir re
Please solve it correctly with a proper explanation of the calculation. Question: Given, you want to visit “welcomebacktophysicalexams.com”. Your network has alocal DNS server and is using a recursive lookup to fetch IP addresses and RTT of 29 ms.Others in your network have already visited the above website a few hours before yourvisit.After fetching the IP address, your PC sends a non-persistent HTTP request of size 109bytes to bring 13 objects of size 31 bytes each. In this particular connection, it requiresthe PC 67ms to send the TCP request to the server. I. What is the total RTT in ms in the DNS lookup?II. What is the total RTT in ms required (including DNS) to bring the full object toyour PC?III. What is the total file transmission time in ms after fetching the IP address?
Using a static route would be suitable in what sorts of situations, and when?
Suppose A, R, and B are as in the previous exercise, except that R's queue now has a size of three packets, in addition to the one being transmitted. A starts a connection using slow start, with an infinite receive window. Fast retransmit is done on the second duplicate ACK (that is, the third ACK of the same packet); the TimeOut interval is infinite. Ignore fast recovery; when a packet is lost, let the window size be 1. Give a table showing, for the first 15 seconds, what A receives, what A sends, what R sends, R's queue, and what R drops.
A connection that connects two hosts may transport many packets at the same time. Please break down how much time is spent on each step of the processing of a freight load for me. Should the duration of one delay be predetermined, while the other delay's time might be flexible, depending on the situation?
Question 23 A client's browser sends an HTTP request to a website. The website responds with a handshake and sets up a TCP connection. The connection setup takes 2.1 ms, including the RTT. The browser then sends the request for the website's index file. The index file references 8 additional images, which are to be requested/downloaded by the client's browser. Assuming all other conditions are equal, how much longer would non-persistent HTTP take than persistent HTTP? (Give answer in milliseconds, without units, rounded to one decimal place. For an answer of 0.01005 seconds, you would enter "10.1" without the quotes.)
