Network software

What Does Network Software Mean?

Network software is defined as a wide range of software that streamlines the operations, design, monitoring, and implementation of computer networks. This article explains the concept of network software in detail and shares useful best practices for network software management in 2022. 

Network software is an extremely broad term for a range of software aimed at the design and implementation of modern networks. Various types of network software support the creation, calibration and operation of networks.

In using network software, the size and scope of a network plays a key role in decision making. Companies or other parties can choose specific network software tools for setup and installation. Other network software resources help administrators and security personnel to monitor a network to protect it against a range of attacks, to prevent data breaches, or to limit unauthorized access. Other tools help to make network operations work better.

Another category of network software is related to network virtualization. With new virtual networks, various tools take the place of old legacy systems built on physical hardware setups.

In general, network software must be applied according to security needs. This can include factors such as whether a network is attached to the global Internet as well as specific goals and objectives for use.

Network software is a fundamental element for any networking system. It helps administrators and security personnel reduce network complexities, and manage, monitor, and better control network traffic. Network software plays a crucial role in managing a network infrastructure and simplifying IT operations by facilitating communication, security, content, and data sharing.

Network software offers useful benefits to organizations. It has become an important tool in facilitating round-the-clock communication and allowing an uninterrupted exchange of information. One of the most significant advantages of network software is its direct correlation with productivity. The centralized nature of network software increases the productivity of the complete system. This helps reduce end-user technical support problems.

For example, if an end user accidentally damages their computer, the chances of losing data are reduced substantially as all its data is already shared on the network. Another key benefit of network software is its ability to enable programmatic management of network resources. This eliminates the need for manual processes, thereby providing a dynamic and efficient network configuration to work with.

Coponents of Network Software

Network software is an advanced, robust, and secure alternative to traditional networking, making the network easier to administer in terms of management, modifications, configuration, supply resources, and troubleshooting The use of network software makes it possible to administer from one centralized user interface while completely eliminating the need to acquire additional hardware. It offers administrators the option to customize with greater flexibility to change and define the network speed, expand network capacity, and look after security.

To understand how it works, let’s look at the components that frame network software.

Types of Network Software

There are numerous types of network software available, with most of them being categorized under the communications and security arena. The varieties of network software differ based on their key features and costs. The main role of network software is to eliminate the dependence on hardware by streamlining communications across multiple devices, locations, and systems. Not only are they extremely useful for end-user hardware (laptops, desktops), the addition of software is bound to have a positive effect on the organization’s everyday functioning and operations.

Let’s look at the different types of network software available today.

Network Software Types

1. Network storage software

In many ways, data within networks is like a child. With time, it only grows, and as it does, it requires adequate attention. Soon enough, data needs to be stored spanning multiple locations and a wide range of devices. Network storage software allows businesses to utilize a standard interface that manages countless databases between users or clients. It serves as a good manager of access between various departments or essential communities within an organization. This way, anybody having access can view or retrieve information with just a click, and at the same time, security concerns are also taken care of.

2. Data archiving software

In today’s day and age of dynamic networks spread across various functioning corporate entities, data once misplaced is data lost. Hence, it is vital to take regular backups. As organizations grow and networks evolve in size, it gets especially tricky to save data appropriately. In addition to that, data that needs to be stored increases at a rapid pace, and its management gets costlier. In such a situation, data archiving software is a perfect choice.

Organizations have heaps of data that might not have to be utilized daily but is still essential to be stored for various purposes, one of them being for regular compliance. Data archiving software enables better management of such information and is an optimal solution to reduce costs while ensuring that the data is being protected. However, as a word of caution, archive software does not function the same way as regular standard backups. Hence, it is always recommended to ensure that the archived data doesn’t need to be accessed soon.

3. Patch management software

It is a nightmare for IT employees to install updates on each device individually. Moreover, when a network consists of numerous devices, ensuring the timely installation of updates is not only expensive but often a cumbersome process as well. As the name suggests, patch management software aids in the smoother management of updates across numerous devices on the network through the installation of patches. This makes the process more seamless and enables each machine to download a patch managed by central software and run updates automatically. Patch management software is the more hassle-free and effective way to perform continuous updates across devices and systems in an organization.

4. Security surveillance software

A majority of network software focuses on data storage and linking devices. However, they do not incorporate protection for a network. This is where security surveillance software comes into the picture. It monitors and connects the various security solutions within a network. Specific software is ideal for large networks as it effortlessly links throughout locations and provides credible browser-based live and recorded footage to an organization. On the other hand, better-targeted software works well in protecting vulnerable units by building a network architecture that reduces attack surfaces, thereby keeping components hidden from any malicious parties. This happens through developing outbound-only connections with cloud services and providers.

5. Asset management software

One of the most challenging tasks in any organization is to keep the network up and running efficiently. Achieving this demands greater visibility of the network infrastructure as well as regular tracking and monitoring of essential metrics. That’s where asset management software comes to the rescue. Compared to most of its counterparts, asset management software operates from a centralized server room or hub and is not connected to any hardware. This is good in terms of cost reduction and offers an excellent experience to the users and clients.

6. Deployment and migration software

Managing a network comes with regular upgrades or movement of assets, and this can sometimes become a herculean task. However, it doesn’t have to be so. The use of deployment and migration software aids organizations in making processes such as upgrading systems hassle-free. The software provides an interface that enables easy monitoring of any deployment or data movement between the hardware and databases within the network. It also ensures mandatory checks on compatibility when any data is being moved between regular backups and archives, thereby significantly reducing the chances of data loss.

7. Printer and fax software

Printers and fax machines are indispensable equipment for any working organization. As an organization grows, so does the number of assets involved within its network. Standard options such as Wi-Fi printing might not always be the best choice, especially for big corporations or schools that span across many floors. This software provides an easy-to-use interface that enables the undertaking and maintenance of multiple tasks. That’s not it! With this software, one can easily set IP printing across networks or even deploy updates. What’s more? In some cases, it can also enable organizations to fax or print important documents and correspondence across different locations.

8. Network management software

In a sea of countless options, why should an organization opt for network management software? The reason is quite apparent. Their primary function is to monitor, manage, and troubleshoot any hurdles in network performance across the whole device infrastructure. While a network monitoring software might have some basic options plugged in to troubleshoot, network management software is equipped to manipulate and modify network performance for the better. These software applications are hosted by several industry-leading brands.

Components of Network Software

1. Application layer

The first component is the application layer or the application plane, which refers to the applications and services running on the network. It is a program that conveys network information, the status of the network, and the network requirements for particular resource availability and application. This is done through the control layer via application programming interfaces (APIs). The application layer also consists of the application logic and one or more API drivers.

2. Control layer

The control layer lies at the center of the architecture and is one of the most important components of the three layers. You could call it the brain of the whole system. Also called the controller or the control plane, this layer also includes the network control software and the network operating system within it. It is the entity in charge of receiving requirements from the applications and translating the same to the network components. The control of the infrastructure layer or the data plane devices is also done via the controller. In simple terms, the control layer is the intermediary that facilitates communication between the top and bottom layers through APIs interfaces.

3. Infrastructure layer

The infrastructure layer, also called the data plane, consists of the actual network devices (both physical and virtual) that reside in this layer. They are primarily responsible for moving or forwarding the data packets after receiving due instructions from the control layer. In simple terms, the data plane in the network architecture components physically handles user traffic based on the commands received by the controller.

The application programme interface ties all three components together. Communication between these three layers is facilitated through northbound and southbound application program interfaces. The northbound API ties communication between the application and the control layers, whereas the southbound API enables communication between the infrastructure and the control layers.

1. Northbound API 

Applications communicate to the controller to present the status of the network infrastructure and request resources based on availability. This communication between the application and the control layer happens via northbound APIs that help instruct what resources the application requires and routes them to the destination in question.

Northbound APIs are majorly RESTful APIs. The control layer decides how the applications are allotted the resources available in the network. Through its automated intelligence the control layer also finds an ideal route for the application as per its latency and security.

2. Southbound API 

The control layer communicates with the infrastructure layer (routers and switches) via southbound APIs. The network infrastructure is informed about the route the application data must move on based on the configurations made by the controller. The controller can control and change how the routers and switches move the data.

A major difference between traditional network software architecture and SDN architecture is that the former’s control and infrastructure layers are integrated. This only allows limited changes to the overall system as the network devices become an obstruction in the logical network traffic flow. On the other hand, SDN separates the control layer from the infrastructure layer and centrally integrates the network intelligence. The centralized and separated operations enable organizations to have greater streght to monitor, deploy, expand, automate, and troubleshoot the network.

Functions of network software

  • User management allows administrators to add or remove users from the network. This is particularly useful when hiring or relieving
  • File management lets administrators decide the location of data storage and control user access to that data.
  • Access enables users to enjoy uninterrupted access to network resources.
  • Network security systems assist administrators in looking after security and preventing data breaches.

Although, it is important to note that traditional networks were hardware-based and comprised elements such as routers and switches with embedded software. The decoupling of software from hardware, called software defined networking(SDN), works exceptionally well to simplify the management of infrastructure, making it more adaptable to the constantly evolving course of the tech world. The introduction of SDN has been a turning point and has completely changed the way networking is done.

Top Advantages of Software Defined Networking (SDN)

Another primary advantage of the SDN process is that it establishes a framework as support to data-based applications like virtualization and big data, which are expected to boost at an impressive yearly rate of 27% according to IDC  However, that’s not all. Here’s the list of the top advantages that enterprises can gain with Software Defined Networking.

Network Provisioning

As mentioned earlier, the SDN framework offers centralized control and view of the overall network. This makes it easier for enterprise management with network provisioning. For instance, creating a Gordian knot of dependencies and links or connecting more VLANs as a part of physical LANs. By extracting the data planes and control, the Software Defined Networking approach improves agility and boosts service delivery, which helps improve provisioning for both physical and virtual network devices from a centralized location.

Reduced Operational Cost

Since SDN enables multi-tasking, the workload on the network operations reduces. This requires less time and equipment and reduces the need for expensive network switches. The SDN process is completely different and much more efficient as compared to the traditional style. This eventually translates into reduced operating costs. SDN also works great with virtualization, which further minimizes the requirement for acquiring more hardware.

Efficient Enterprise Management

Enterprise networks are expected to establish virtual machines and new applications on demand to fulfill the latest requests based on big data analytics. With the help of the SDN approach, IT managers can experiment with network configuration without affecting the network. Moreover, SDN also helps with management support of both virtual and physical network devices and switches from a central controller – a process not possible with SNMP. An enterprise has access to single APIs for establishing a single console for management for virtual and physical devices.

Security Approach

When you have a single-management console for networking, it becomes easier to monitor and control your security features. You do not have to work with or rely on multiple applications across the system. You can simply work with one central point and use it to have a stronger approach to security. The same console can also be used to spread information in case there’s a security-related alert. Virtualization has made it more challenging for IT managers to keep up with network management. With several virtual machines attached to the physical systems, applying filtering policies and firewalls can be difficult. With SDN, both information and security policy can be controlled and distributed consistently within the enterprise.

Reduced Capital Expenditures

As mentioned earlier, SDN brings the existing network devices to life. It utilizes and optimizes commoditized hardware, making the process even simpler. Using the existing hardware for different purposes reduces capital expenditure. SDN allows deploying the same hardware with great effect due to the intelligent SDN-centered controller.

Operational Control

This is, in fact, one of the major reasons why the whole approach exists. The point is to be able to influence the overall operations using a single console. This is done with the intention of boosting the ability to have better control over task allocation and network traffic. Also, the centralized console can be used to improve the productivity of the enterprise’s network and systems.

Cloud Abstraction

Cloud computing is the elephant in the room that cannot be ignored. The technology is here to stay and is evolving at an impressive pace. It has transformed into a unified infrastructure that businesses of all sizes and industries are putting to good use. By abstracting cloud resources with the help of an SDN, the enterprise can easily unify cloud resources too. There are various networking components, which translates into a massive volume of data, can also be managed and monitored with the SDN controller.


The amount of automation you can leverage out of a Software Defined Networking process can help you in various ways. It’s the best way to invest speed in the overall networking operations. Unlike before, today’s network does not have to struggle with internet connectivity. With SDN, it is also possible to alter automated responses in the cloud. The process works particularly good in environments such as enterprise-wide SD-WAN networks.
