What is a P2P network?
Computers are a fundamental part of our quotidian lives but if they not were connected to one another they wouldn’t serve as much as a convenience to us. There are several reasons why computer networks are so widely required. For e.g., Communication, Resource sharing, hardware. They make communication easier by providing access to email, VoIP (Voice over Internet protocol).
The old days are gone where data transfer deals with a maximum of 1 Mbps or even in Kbps, where to transfer data from one device to another takes hrs. of time for completion. But now with the advancement in a computer network, this problem stands no more. In the calling, the online chat service wasn’t the first to allow people to make voice calls over the internet. With the entry of skype, it made it possible for us to call using the Internet, and the root of technology which is responsible for is the P2P network.
In this technological life we always use the term “Network”, so what is Network? A way of communication is developed by connecting various Output devices such as printers, servers, etc.
In Today’s world sharing information and resources is becoming an important or vital part of our daily routine. The same goes for our IT Industry where the P2P network helps run a business more efficiently by improving connectivity and access to shared resources (files or folders over a network).
What is Peer to Peer (P2P) Network?
P2P Network is an infrastructure or technology in which two or more computers are connected in order to share resources. An independent network system that does not require a system administrator for managing the network. This type of network is based on Peer-to-Peer architecture. Peer-to-peer (P2P) architecture is mostly implemented over the computer network architecture because in this system every workstation and other nodes have equal abilities and responsibilities as well.
Peer-to-peer architecture is designed using a software program where every piece of the program performs their all instructions as both client and server along with similar responsibilities and capabilities. In other words, every peer plays the role of both client and server.
There are 3 methods for establishing connectivity through a P2P network. Firstly, we can use a basic method i.e., to connect USB to make connections b/w two peers. Either using copper wires to make connections. Implementing Protocols that help to control all connections between terminals of an intranet.
What makes peer-to-peer networks useful in the networking Domains? There can be many use cases where they are useful. Like for e.g.
- Powerful Protection b/w computers with strong Network Security Software’s.
- Each peer or computer in a P2P network shares a part of its resources with other networked computers in that intranet. These resources may contain storage, bandwidth, and processing power.
- Monitor your entire network continuously and protect from attacks of malware.
- When it comes to file-sharing, the immense peer-to-peer network is, the faster it is.
- It’s hard to take them down. Even if one of the peers collapses, the others are still operating and working.
P2P (peer-to-peer) network examples:
On a daily basis, we share some resources and content in Terabytes. Acquiring Server doesn’t fit everyone’s pocket, so a less expensive solution is peer-to-peer networks which one can use to connect computers and devices without the need to configure a server. Having to create a server
for everything is expensive and difficult to control, so in some situations, it’s easier and more budget-friendly to use P2P networks. Here are some examples of common use cases for peer-to-peer networks.
- Torrents: – where all major contents are shared such as movies, games, software etc.• Microsoft delivers updates from both its servers and P2P networks.
- Windows 7, Windows 8.1, or a Windows 10 version before Version 1803, provides an option by which we can connect the computers in your home to a Homegroup, thus, creating a peer-to-peer network between them.
- Earlier Operating Systems Such as Windows 7 or 8 provided the option to create an ad hoc network between two computers, which establishes a peer-to-peer network between them.
- Some of the Applications can be Instant messaging, High-Performance Computing.• Multicasting streams can be used to provide demand on content to various peers.
However, as in all networking models, peer-to-peer networks possess advantages as well as disadvantages. By looking at the pros and cons, the users can decide how beneficial the P2P network is.
What are the Advantages of a P2P network?
- Easy file sharing: A P2P network can share files quickly over large distances.• Cost: building and maintaining a peer-to-peer network is relatively inexpensive. The setup cost has been greatly reduced due to the fact that there is no need for central configuration as compared to other networks.
- Performance: Due to the best scalability, it offers better performance because whenever a user wants to add new peers, it will not degrade the performance of the network.
- 24*7: Users can find all files at any time because its collection of all files is available 24*7 times.
- If anyone peer of this network stops working then the entire network will not be affected.
- Without any proper knowledge of this network, you can easily configure this P2P network
What are the Disadvantages of a P2P Network?
- Security: -Security for resources is comparatively less in peer-to-peer networking. The only option we have is that we can assign some permissions to users.
- Every peer will have a unique password over the whole network.
- No Central storage of data will be there, some of the files can be on one peer and another on different computers which will disturb database collection.
- Backup is very difficult to recover in P2P networks since the data is not centralized. It is saved on various systems. There should be a policy there that backup needs to be done separately on each computer. Or else there should be a backup reserve for every computer.
- The performance will be slowed as many peers are accessing it at the same time.
- Most of the time, we have seen that p2p networks play a role in transferring copyrighted content like movies and music by implementing torrents.
- Speed of Internet connection can affect while uploading and downloading simultaneously
As addressed in my analysis of the above article, the advantage of a peer-to-peer network is ideal for home uses or small businesses. A cheaper model rather than set up client-server networks. An unexceptional advantage given by this type of network is that all group members maintained a replicated store containing all shared data of the group.
