Peer-To-Peer Communication – Advantages & Disadvantages

Peer-to-Peer – What is it?

The peer-to-peer communication model is one, where all the participating nodes or the computers are equal peers without any privileged benefit for a specific node. That is, there is no one boss aka a governing source but, all of them are equal peers, who collaborate together to produce the desired output quickly. So, how beneficial is this peer-to-peer communication model? Let’s understand this better by looking into its pros and cons.


  • A peer-to-peer network is easier to set up, as there is no concept of the centralized source. That is, here, each participating computer can manage themselves, and therefore, to set up such a network, shouldn’t take so much of your time or the effort! Also, when the new nodes get added to the network, no special configuration to set-up permission or the accessibility for these nodes is required, since there is no central governing authority.
  • A peer-to-peer network is more reliable, which attributes to the absence of a central governing source. Say, if the specific source is acting recklessly that would lead to lots of problems on the network, including hackings and misappropriate sharing, which could not happen in the case of a distributed network model like the peer-to-peer. Here, all the resources and all the contents are shared equally by the peers of the network and that leaves no room for any shady activities or reckless behaviors, fortunately! Also, lack of the central figure eliminates the possibility of recurring failures in case of any collapse in the working model, as the other peers can compensate for the failed node, appreciably!
  • Since the peers share the workload among themselves, the required output is achieved quite quickly. That is, here, any node can interact with any other node of the network instantly, without the need for any special permission and therefore, the desired output can be achieved pleasingly quickly all the time!
  • Since, all of the nodes, share all of the things among themselves, they are equally aware, or in other words, the security of the network increases multifold. In the case of a centralized network, if the governing source acts inappropriately, that decreases the security of the network, which cannot happen in the case of the decentralized peer-to-peer communication model.
  • It is an inexpensive network to set up, as there is no central configuration to be set up! That is when there is no central configuration to be cared about, no special privileges, access, etc. has to be taken care of while setting up the network that reduces the installation cost of the network.


  • The lack of a governing model can prove disadvantageous too, especially when the network grows in number and frequent conflicts arise between the participating nodes of the communication model.
  • Every peer of the network should act responsibly to ensure the safety and reliability of the network all the time. If a particular peer decides to work in unison with the hacker, although the intention might be eventually curbed, there is a certain amount of damage that has been already done and that, cannot be recovered.
