Types of Backbone Networks

Types of Backbone Networks

You probably know that there are three types of backbone networks: Distributed, Switched, and Flat. Which one suits your needs best? Let’s explore these in more detail. Listed below are the benefits of each type, and what each one does best. If you’re unsure of which one to choose, consider these examples. These types of networks are the most commonly used, but there are several others you may want to consider as well.

Switched backbone

There are many different types of backbone networks, including switched, wired, and wireless networks. Switched backbone networks provide point-to-point connections at 155 Mbps. They can be highly flexible, as rack-mounted equipment can be moved from one LAN to another.

Switched Ethernet uses multiple encapsulation schemes, allowing data to pass between switches at different speeds. For example, switched Ethernet uses variable-length frames rather than fixed addresses to prevent address conflicts.

The Switched backbone is a logical structure that clearly segments the network into subnets. Each subnet is given its own subnet address, enabling it to be managed separately. This helps to improve performance. In addition, a routed backbone separates each network segment into independent subnets. Previously, the network was not fault-tolerant, and media could not be loaded because of format or failure.

Distributed backbone

The idea behind a distributed backbone network is to provide a scalable link between two points. In a traditional backbone, each node serves a single purpose – to transport data. However, modern backbone cyber-infrastructures can scale to cover vast distances. While most existing recovery schemes focus on single or limited-dual node failure, new research focuses on hardening performance in realistic settings.

In a distributed network, each switch is connected to multiple locations through a single backbone cable. To implement a WAN, multiple LANs are linked together using fiber. In a distributed network, each LAN has a network administrator who oversees its hardware and software. In a traditional LAN, the network administrator is responsible for maintaining the LAN and designing connection schemes between the remote segments. He or she also works with voice and data systems to plan upgrades and hardware.

Flat backbone

The Flat backbone network is a type of Internet connectivity. It is made up of a large number of points of presence that link together. Backbone providers concentrate their points of presence in densely populated areas, where the demand for Internet service is highest. These points are then connected to users located in far-flung areas via telecommunications lines. A hypothetical Internet backbone network is shown in Figure 1, incorporating links at interconnection points that take traffic from residential users via ISPs to large business users directly.

To make this type of network, the distance between the transmitter and receiver must be relatively short. The hop frequency should be no less than m. The network should also be capable of covering a sufficient range of transmission. The energy used during a transmission is proportional to the distance. The amount of energy consumed by backbone nodes varies with distance, but the energy consumption is the highest at the transmitter and receiver. Hence, in short-range transmissions, the nJ value should be used. In addition, path loss and energy consumption are considered. The transmission power should be low in the case of short-range transmissions.
