How much time does Non-persistent HTTP and no concurrent TCP connections expire if DNS searching up occurs once per 10 minutes, and each time the HTTP file mentions 8 objects?

Step by step
Solved in 2 steps
- If a DNS lookup happens every 10 minutes and an HTTP file references 8 objects each time, how long would Non-persistent HTTP with no concurrent TCP connections last?If a DNS lookup is performed every 10 minutes and an HTTP file references 8 objects each time, how long would Non-persistent HTTP with no concurrent TCP connections last?if DNS looking up happens once every 10 minutes, and each time the HTTP file references 8 objects, how much time elapses with Non-persistent HTTP, and no parallel TCP connections?
- Download delays for 100 objects (HTTP 1.1 with browser caching). Consider an HTTP 1.1 client and server. The RTT delay between the client and server is 2 seconds. Suppose the time a server needs to transmit an object into its outgoing link is 3 seconds, as shown below for the first of these 100 requests. initiate TCP connection RTT request file RTT file received time You can assume that any other HTTP message not containing an object sent by the client and server has a negligible (zero) transmission time. Suppose the client makes 100 requests, one after the other, waiting for a reply to a request before sending the next request. 352 secs Using HTTP 1.1, how much time elapses between the client transmitting the first request, and the receipt of the last requested object, assuming the client uses the IF- MODIFIED-SINCE header line, and 50% of the objects requested have not changed since the client downloaded them (before these 100 downloads are performed)? 350 secs 252 secs time to…Consider a web page, which contains 6 objects. How many RTTS does it take to download all objects in this web page: (a) Using non-persistent HTTP (b) Using persistent HTTP without pipelining (c) Using persistent HTTP with pipelining.If DNS searching happens once every 10 minutes, and each time the HTTP file references 8 items, how long until non-persistent HTTP and no concurrent TCP connections expire?
- The following questions are related to HTTP protocol Q1. The first line of a HTTP request from some client to some server is basically made of where the web page file path is added. The path is shown as folders separated by slash. Q2. If an HTTP server responds to a client request and the response is a success, what is the http code and string that marks a success response? Must provide the code and the string as they appear in TCPDump or Wireshark traces. (note: use upper case for the string and also proper spacing in you answers. Keep the order of the string and the code as seen in TCPDump) Answer: code and string that marks a success response Q3. What http header field is used to identify an address of a web page (i.e. the URI) that linked to the resource currently being requested. This field indicates the last page the user/requester was on by the time they link to the requested page. Answer: The field that indicates the last page the user/requester was on is Q4. What is the http…What is the average object download delay (the sum of the four object download delays divided by 4) under the HTTP/2 object frame transmission order shown?Computer Science Networks and should be done in C language. Create a UDP client and server program that not only is able to locally transfer files but it gives the client the ability to send multiple copies of the file to multiple servers. Once the server program is initiated, it waits until it receives client packets. It then reads and saves the payload of the packets. The client reads a file from the disk and sends it to each server over a UDP socket by breaking the file up into mtu-byte sized packets. Client needs to be concurrent in sending the packets to all of the servers using threads
- In HTTP version 1.0, a server marked the end of a transfer by closing the connection. Explain why, in terms of the TCP layer, this was a problem for servers. Find out how HTTP version 1.1 avoids this. How might a general-purpose request/reply protocol address this?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.)When HTTP streaming is being used, are the TCP receive buffer and the application buffer on the client both the same thing? If they are unable to speak with one another, it is unclear how they will behave toward one another.
