Changes have occurred within business networks due to the emergence of cloud apps, distributed employees, branch offices, and digital services. There may be cases where traditional methods of networking become challenging to handle because there is a need for efficient flow of traffic among different resources.
SD-WAN technologies have enabled organizations to deal with the aforementioned issues in a better way by offering flexibility and centralization in managing their network connectivity.With SD-WAN Products for Modern Networks, organizations can gain greater control over traffic, improve application performance, and simplify network operations.
What Is SD-WAN?
SD-WAN stands for Software Defined Wide Area Network. It is basically a software-defined method of managing wide area networks. SD-WAN does not depend solely on hardware-based routing but uses software to define the routing policy depending on real-time network information available at that time. Businesses will be able to effectively manage network performance and connectivity in this manner.
Businesses will be able to manage different connectivity options through SD-WAN, which include broadband, MPLS and cellular connections. Paths can then be selected automatically in order to ensure suitability according to application needs, network situation, etc.
Why Traditional Network Management Is Becoming More Challenging
The modern enterprise creates network traffic from numerous different sources. Staff may connect to cloud apps from different locations; branch offices may rely on internet services; and mission-critical applications may need predictable performance.
Manual management of these network environments is prone to the following problems, among others:
- Poor visibility of distributed networks
- Complex configuration and troubleshooting
- Reliance on connectivity service providers
- Problems with prioritization of critical applications
- Growth in demand for cloud connectivity
- Higher security and access needs
This has prompted companies to look for more automated ways to manage their networks.
How SD-WAN Is Changing Network Management
SD-WAN will change the way networking is managed by making things easier for companies to handle their networks. It will make it easier for IT professionals to manage their networks and help them handle their networks more efficiently.
It makes things more convenient for the IT professional in terms of managing the network. They will be able to manage their network better without having to manually configure the network.
1. Centralized Network Management
Centralized management is one of the important aspects introduced by SD-WANs in network management. Rather than configuring every individual branch separately, IT personnel would be able to centrally configure their policies and settings.
This would save time that would otherwise be spent on network management and administration.
2. Improving the Utilization of Multiple Connections
An organization may have multiple types of connections in its network infrastructure. The SD-WAN will be able to effectively manage the traffic through these connections considering such aspects as application demands, availability, and performance. It will help in the better utilization of connections rather than using only one connection for all the traffic.
3. Improving Application Improvement
The cloud applications, video conferencing, VoIP, and other services may require different network capabilities. The use of SD-WAN will allow you to recognize traffic belonging to applications and implement the policies according to business needs.
For instance, some critical business applications will be given high priority in case the network condition changes.
4. Simplifying Cloud Connectivity
When moving their applications and processes to the cloud, companies might face problems caused by the traditional way of setting up a network. In this situation, the use of SD-WAN can allow companies to set up a faster connection between users, branches, and clouds.
It will enable faster connectivity to SaaS platforms and cloud applications.
5. Facilitating Distributed Business Operations
The network for organizations that operate from multiple office locations or have employees working remotely requires the ability to accommodate changes in connectivity needs. This capability is offered by SD-WAN, which allows companies to set up new office locations and handle their existing branch offices without having to manually configure everything each time.
How SD-WAN Supports Modern Network Security
Network performance is not the sole concern in modern network management systems. With the interconnection of remote employees, branches, cloud applications, and distributed network assets, security becomes another issue that needs to be addressed by today’s businesses. SD-WAN technology may become helpful in reconciling the needs for connectivity and security.
The most important capabilities of the security system could be:
- Integrated Firewalls: These would assist in inspecting and managing the network traffic according to the security policies that have been defined.
- Encryption: Ensures security for the transmission of the data over the network between the branches and through cloud and user environments.
- Network Segmentation: This would help in segregating the confidential resources and minimize unnecessary communications between the network segments.
- Access Controls: Limits users or devices to use only those resources to which they have access according to their authorization.
- Traffic Visibility: Would provide visibility of the network traffic.
What Businesses Should Consider Before Adopting SD-WAN
Businesses need to consider SD-WAN from various perspectives before deciding to implement it. The following table summarizes some key points to consider:
| Consideration | What Businesses Should Evaluate |
| Network Readiness | Evaluate the existing infrastructure, connectivity, and locations of branches. |
| Security Alignment | Test integration with firewalls, encryption, segmentation, access control, and other security technologies. |
| Cloud & Application Needs | Consider the way that SD-WAN will support cloud, SaaS, and critical applications. |
| IT Team Capabilities | Think about whether your internal team is competent enough to handle the platform. |
| Scalability | Make sure that the solution has the capacity to accommodate future users, applications, branches, and traffic. |
| Integration | Ensure interoperability with current networking, cloud, and security solutions. |
| Deployment Planning | Implement the system in phases to minimize disruptions and discover problems sooner. |
| Total Cost | Keep licensing, hardware, connectivity, implementation, and support costs in mind. |
| Performance Testing | Conduct a pilot implementation to test reliability, system performance, and suitability before implementing fully. |
The Future of Modern Network Management
With cloud services becoming more important and with the growing number of remote workers and branches, the need for network management becomes increasingly complex. Traditional approaches may not offer enough flexibility, visibility and control to address this ever-changing situation. The future of network management lies in increased automation, visibility, intelligent traffic management and integrated security. Companies will require networks that can adapt to changing demands from applications, connectivity and users without continuous manual configuration.
The SD-WAN approach offers companies an improved way to control their network traffic and its prioritization. It may be helpful for companies to manage several types of connectivity more efficiently while enjoying centralized network management over distributed locations.
As more and more companies adopt cloud computing and enable employees to work in hybrid environments, SD-WAN will become even more useful to establish connections between users, branches, applications and cloud services.
Final Thoughts
SD-WAN is revolutionizing the process of networking within the corporate world, through increasing flexibility, centralization, and responsiveness to applications and business needs.
