To guarantee that a company works smoothly and swiftly, data activities require good communications between offices. SD WAN is one solution for quickly transforming a sluggish connection and long wait times into a fast and responsive network where everyone has access to critical information. What exactly is SD WAN, and how does it differ from other options? We’ve taken this opportunity to describe the benefits for you; keep reading to find out more.
SD WAN Defined
While internet services differ in different locations, it should not affect the network connections that your company relies on to communicate and store critical information. SD WAN or Software-Defined Wide Area Network uses software technology over the existing internet connections to allow encrypted communication and file sharing between an organization’s locations. The goal is to provide a high-performance WAN using low-cost commercial internet and partially or wholly replacing more expensive and complicated commercial technologies.
How Does SD WAN Work?
SD WAN is designed to address network congestion and packet loss problems by replacing or enhancing traditional branch routers with virtual applications that can control policies and offer a network overlay of the less expensive internet options. Doing so creates a more dedicated circuit and simplifies setup for branch personnel. The SD WAN Edge is a physical or virtual network function that is located at the main office and controls the companies cloud usage.
What are the Benefits of SD WAN?
Because of its ability to identify failures and switch to functioning lines, SD WAN is robust and decreases network downtime. It also allots priority bandwidth to the services that are most important to corporate operations, therefore enhancing the services provided. The ability for the SD WAN to be used over any internet connection gives traveling associates the ability to connect to the office and provide critical communication from any location including home or on the road. Having centralized management tools for administrators to control the network activity increases the performance while simplifying setup, especially in connecting new users.
SD WAN Use Cases
There are a few good use cases for why a company should invest in an SD WAN. In cases where the branch connectivity is sluggish, there is no central cloud connection, security is lacking, the network isn’t visible, and management of the network is different in each area, there is a need for conversion to SD WAN. Centralizing the network into a cloud-based, main branch-managed software that can be accessed by any branch over a simple internet connection increases the productivity of the business. Who would need a solution like this? Any business that has traveling employees, several offices, or is planning expansion to new locations.
Is SD WAN Secure?
One of the biggest concerns for businesses is the security of their connections. SD WAN is driven by the need to secure application connections. It has the capability to use firewalls, intrusion prevention, URL filtering all before the information is routed to the cloud to prevent misuse or corrupted information from causing issues. Extra security can be added onto the approved devices increasing end-user security and further preventing unauthorized access.
Who Provides SD WAN?
Several companies have begun to offer the services of SD WAN including:
- Aryaka Networks
- Silverpeak Unity Edgeconnect
- Palo Alto
There are many other companies that can provide the service to your business, so how do you decide which is the best? Comparing and contrasting the different service providers is easier with assistance from companies like Cteleco who reduce your time obtaining quotes from different companies and streamline the installation process.
How to Get SD WAN?
Allowing Cteleco to cut out the quote solicitation process and connect your business to the best provider options for your business is the fastest and simplest way to convert to SD WAN. Take the time out of the setup and allow Cteleco to guide your business into the SD WAN transformation seamlessly, instead of calling around to request services or piecing together the technology manually.
SD WAN vs WAN
What is the difference between SD WAN and WAN? Traditional WAN does not provide swiftness, security, and requires human interaction for configuration. WAN also requires the user to connect to a local hub before connecting to the cloud slowing the performance of the applications. WAN equipment installation and expansion requires 3-4 days to set up new locations where an SD WAN installation can be completed within a few hours.
MPLS vs SD WAN
Multiprotocol Label Switching or MPLS is designed to move packets of data efficiently across the network directly from one location to another. The information travels along a predetermined path to reach its destination. However, the increased cost of MLPS, its fixed and inflexible connections, and high bandwidth usage impact the company’s production, reducing the rate of communication. MLPS also does not provide ample security options.
SDN vs SD WAN
Software-Defined Networking is able to provide on-demand services while reducing cost and improving scalability and performance. Both SDN and SD WAN are seemingly closely related and can seem like the identical twins of the network family. However, their uses set them apart. SDN manages local area networks LAN within an office and SD WAN connects geographical locations. Both can be virtualized and used at the same time to connect devices within an office to the geographical locations of other offices. The combined use of the two systems can support a business’s desire to use cloud technology first.
SD WAN provides companies the opportunity to decrease internet costs with a software-based connection that allows connection over broadband commercial internet. It provides superior security, increased performance, easier installation and maintenance, and reduces downtime by using active lines when a fault is detected. The flexibility of the SD WAN connections allows users to travel between geographical locations without losing their work or having difficulties accessing critical functions. While there are many companies that provide SD WAN services, Cteleco makes it easy to compare services and initiate installation without sorting through the providers’ quotes.
