What is a Point-to-Point Network?

A point-to-point network is a type of network architecture in which only two nodes of each data channel are used to communicate, as opposed to multipoint networks where each data channel can be used to communicate in a variety of ways.

What is a Point-to-Point Network?

Point-to-Point Network

A point-to-point network is mainly used for sending private and confidential data securely between two secure locations. These networks are usually made through fiber-optic or wireless links.

In a Peer-to-Peer network, devices connected to the network communicate with each other equally or in pairs. In a peer-to-peer connection, each device connected to the network is configured as a master or slave.

Therefore, these networks are very easy to design, configure, and set up. However, as the number of devices added to the network increases, it will be very difficult to manage these connections and ensure their operability, and network efficiency will decrease due to the high number of devices on the network.

When connecting the nodes of a network in this structure, the communication type they carry is configured as Simplex, Half Duplex and Full Duplex.

In a unidirectional data transmission, network traffic occurs only in one direction, while in a half-duplex data transmission type, network traffic occurs in both directions. However, bi-directional traffic must wait for each other to complete before transmitting on both channels at the same time.

In full-duplex data transmission, network traffic occurs in both directions simultaneously. Since the speed of Half-Duplex and Full-Duplex connections is the same in both directions, this type is also called asymmetric connection.

Features

It is used to connect long-distance networks with WAN structure in two different locations.

In this network structure, the implementation of routing algorithms is often more complex. Also, error checking is performed on intermediate devices in addition to endpoints.

Networked devices only receive messages transmitted by network nodes. In this case, data transfer takes place from the destination address of the message defined by the receiving device.

The connection between such links can be made with a transmission system operating in parallel. Network delays that may occur from the transmission system in the interconnection result from the transmission of messages through intermediate nodes.

In this case, since the End-to-End connection is made through intermediate nodes, the reliability and efficiency of the network traffic depend on them.

Cabling costs for this network depend on the number of connections between computers, and each node has at least two interfaces.

These networks are also known as distributed networks. Therefore, users can easily access the resource shared by each computer on each node. But if two or more networks are connected, users cannot utilize the full efficiency of the network.

Advantages

  1. It is easy to configure and apply.
  2. It is less complex than other connection types.
  3. It has lower costs as no network devices or special servers are required.
  4. It allows connecting LAN and WAN networks to a single central network.
  5. It ensures that company employees are connected to the central network and provides better information exchange.

Disadvantages

  1. Provides decentralized management.
  2. It does not create a very secure and scalable network structure.
  3. As the network grows, productivity decreases.

How Does It Work?

This network can connect them with fiber optics if a company’s ancillary service building is located close to, for example, 25 km. This connection is made by network equipment provided by the ISP.

It can be included in the ISP’s fiber-optic network to connect networks available at more remote locations. Thus, the network traffic runs separately from the Internet connection, creating a private network of the company.

Thus, a single point-to-point connection between two locations enables multiple locations to be linked to a data center. In this case, the bandwidth of the same network with other users is not occupied and efficient performance is obtained with faster data transfer and lower packet loss.
