What is Network Redundancy in Computer Networking? – Network Redundancy implemented on a network allows the transmission of data packets over another alternative network cable in case of failure of a specific network cable used for data transmission.

A large corporate network is always required to provide continuity. By ensuring network success in a large corporation, it means that the institution can always serve its customers. If a corporate network is not well designed, it will face constant faults.

Not to serve an enterprise network will result in loss of customers, commercial loss and loss of customer credibility.

Failure of a single connection on a network or a single connection point on a Switch will result in a disconnected network. Therefore, multiple ports must be configured on the Switch or Router to ensure continuous network performance.

Multiple configured ports will greatly increase the cabling requirement. Because multiple paths to a path will be created. Network redundancy is always required if the cabling requirement results in high costs.

For example, let’s consider a network where web servers are hosted. This network is certainly not a service feature. If a company owns a website on these servers, the website must always be active. The agency that provides this service should optimize customer service. Otherwise, a bad service will lead to customer losses.

Network redundancy means that a particular destination has two different paths. And as a result, more than one cabling need.

Network Redundancy Advantages

It is innumerable the benefits of network redundancy, but it has some key advantages. These;

1. It reduces congestion on the network.
2. It increases High availability on the network.
3. It provides load balancing on the network in a large amount.

Network redundancy on the network is a major challenge, but there are some disadvantages. Switches connected to each other in a network can create a Loop. And if the network broadcasts continuously in one direction, this will cause a broadcast storm on the network.

When the broadcast storm occurs, the bandwidth on the network will be used in a large proportion. With this problem, many mistakes on the network will come into play.

In addition, single broadcast frames, multiple frame transmissions, and MAC table creation issues will arise. If a source computer does not know the target computer’s MAC address, the source computer will send a Broadcast (ff:ff:ff:ff:ff:ff) to the network environment and the target computer will want to learn.

Because the Switch that receives the Broadcast on a backed-up network will send Broadcast from each port, the target computer will respond to two or more broadcasts, resulting in large network traffic and MAC database bottlenecks.

The only way to prevent such problems is to configure the STP Protocol on the Switches. With STP, you can disable a backup connection, and if the other connection fails, the disabled connection will be automatically enabled.

As a result, the loop on the network will be prevented by STP.

  Final Word

What is Network Redundancy in Computer Networking? – Network redundancy is strongly recommended for continuous delivery of data transmission in network design. The networking design of large institutions provides continuity and good service. Network redundancy eliminates customer dissatisfaction or network disruption issues, even if it greatly impacts costs.
