3.1.1 State of the underlying network and its quality The speed of how quickly a file could be

Why would you use http or ftp instead of bit torrent for downloading large files? == you would use ftp because it does not have client authorization needed, and you would use http because it connects directly to a server to download when with bit torrent uses more TCP connections which can be blocked by firewalls..

sharing workload in KaZaA [8] and [18], to our knowledge we are the ¯rst to undertake

Download speed – the amount of data the user can download per second and is capped by their ISP. The slower the download speed for the user the slower the user can download the webpages and assets to view the website so the company will have to have to take their customers download speeds into account to decide what size of files is appropriate for their audience to access their website as quickly as possible.

In the configuration, we set a 200 m/s as the transfer rate and see the effect on one of the conference servers. However, with 5 conference server, we are not able to see the effect since the CPU and network load is

This traffic shaping tech prioritizes gaming and video streaming to smooth out connection speeds for a better overall experience. This is done by allocating and limiting portions of the bandwidth based on the type of data being transferred. If someone gets on one computer and starts a large download, it will not affect someone watching a movie on a different computer.

// - FTP/TCP flow from n0 to n3, starting at time 1.2 to time 1.35 sec.

It is operating on best effort delivery model, i.e. it does not guarantee delivery, nor does it assure proper sequencing or avoidance of duplicate delivery. These aspects, including data integrity, are addressed by an upper layer transport protocol, such as the Transmission

Using CDN servers will make the delivery of your content faster. There will be less traffic in these servers making them deliver your static content at greater speeds. The closer the CDN server is to the user, the user will obtain your content much faster.

I would define a network as a group of computers that are connected together with physical cables or wireless capabilities along with a series of peripheral devices such as, routers, switches, servers or printers etc…for sharing data, software and other resources between different users. When talking about bandwidth, it is a range of frequencies or wavelengths in which data is transmitted. With digital devices, bandwidth is calculated by bits per second or bytes per second and with analog devices, by cycles per second, or hertz.

Now coming to the question, whenever you are downloading any file or software over internet it takes time to get downloaded depending on the downloading speed of your internet connection. Similarly, if we refer to the question and assume to download a MP4 format movie of total size 2.4GB (gigabytes), the downloading time of our movie will depend on the type of connection we are using. Below are few types of connection which can tell how long

load of servers and to increase access locality. It happens by changing the the amount of data or number of servers.

1. Speed: While a transfer rate of 25 Mbps sound fast, Wi-Fi can offer up to 250 Mbps (Thadani, 2015).

Not everyone thought this was such a great idea, however. Some objections cite legal or moral concerns. Other problems were technical. Many network providers, having set up their systems with the idea that users would spend most of their time downloading data from central servers, have economic objections to peer-to-peer models. A long-established fixture of computer networking that includes important peer-to-peer components is Usenet, which has been around since 1979. Usenet news implements a decentralized model of control that in some ways is the grandfather of today’s new peer-to-peer applications such as Gnutella* and Freenet*. Fundamentally, Usenet is a system that, using no central control, copies files between computers. So the bottom-line is that file-sharing has been around for a long time now and that its decentralized nature makes is hard to control besides holding each individual sharing files accountable. Peer-to-peer systems go hand-in-hand with decentralized systems. In a fully decentralized system, not only is every host an equal participant, but there are no hosts with special facilitating or administrative roles. In practice, building fully decentralized systems can be difficult, and many peer-to-peer applications take hybrid approaches to solving problems. [1]

The ability to send and receive data efficiently is the most important objective of networking computers.

Latency: bitcoin network is currently taking 10 minutes to complete one transaction and in other systems it takes only few seconds to complete the transaction.
