Peer-to-Peer Model
Peer-to-Peer Model
Peer-to-Peer Model
In a peer-to-peer (P2P) network, each computer is directly connected together. This removes the need for a central server.


Peers
Peers
- Each computer on the P2P network is known as a peer.
- Each peer can act as both a client and a server depending on what task they are trying to accomplish.


Uses of P2P networks
Uses of P2P networks
- P2P networks are commonly used for:
- File transfer.
- Streaming video from computer to mobile or TV.
- Wireless printing.
- Bluetooth speakers.


Responsibility
Responsibility
- Each peer on the network is responsible for their own maintenance and making sure that they remain connected to the network.
Pros of the Peer-to-Peer Model
Pros of the Peer-to-Peer Model
Some networking problems are well suited to peer-to-peer (P2P) networks, whereas others are more suited to client-server solutions. In any case study, you should weigh up the advantages and disadvantages.


Easy setup
Easy setup
- A P2P network is very easy to set up.


Cheap
Cheap
- A P2P network is cheaper than a client-server network.
- No expensive or dedicated hardware is needed.


Robust
Robust
- A P2P network has no centralised server.
- If one peer fails, the others can still use the network.
Cons of the Peer-to-Peer Model
Cons of the Peer-to-Peer Model

No central maintainence
No central maintainence
- Without a central server there is no central management.
- This means that we cannot update the software and security of the peers as easily.


File duplication
File duplication
- Files have to be duplicated and transferred between machines.
- This can lead to multiple versions that can become out of date.


Peers may lose connection
Peers may lose connection
- Peers may lose connection when we are trying to access them.
