Types of Networking between Hosts

Defined

Networking between hosts refers to various methods and mechanisms by which data is transferred between devices (hosts) within a network. These devices can be computers, servers, routers, and other related hardware.

In peer-to-peer (P2P) networking, each host, or node, in the network can act as both a client and a server.
P2P is ideal for networks with a small number of hosts and does not require a central server to manage network connections.
All hosts are responsible for their security, which can be a downside if not handled responsibly.
File-sharing systems like BitTorrent are examples of P2P networks.

In client-server networking, one or more central servers have the data or applications and provide services to the client hosts on request.
Servers are usually more powerful and have more storage capacity than clients.
The burden of security lies mainly on the servers.
Most businesses and larger institutions utilise a client-server model due to its centralised control and scalability.

Hybrid networking combines elements of both client-server and P2P networking.
This model benefits from the strengths of both models, such as the centralised control of client-server models and the shared responsibility of P2P models.
An example of hybrid networking is VoIP services such as Skype.

Cost: Consider the initial setup cost and maintenance cost, which can vary depending on the model used.
Scalability: The network should allow for easy addition or removal of hosts.
Data Security: Consider the security issues and data protection measures in place. In P2P networks, each host is responsible for its security, while in client-server networks, main responsibility is on the server.
Functionality: The needs of the network should dictate the type of networking model. P2P may be suitable for small networks while client-server models for larger ones.
Performance: Evaluate how each model will influence network traffic, latency, and overall performance. Client-server model is usually more reliable and faster, while P2P can depend on the host’s connectivity and resources.
