Switching to SD-WAN is becoming a popular choice for companies around the world.
However, using traditional WAN is the right and reliable way to provide and receive network services. In some cases, a hybrid system may be more useful if both are in the game. Of course, it depends on the needs and circumstances of each individual company.
Whether your business continues to rely on traditional WAN, completely switch to SD-WAN, or using some combination of the two, you need to know the basics of these two technologies.
Because it integrates traditional WAN technologies such as MPLS with broadband services, SD-WAN is a unique way to communicate over a wide area. This allows the company to train in remote areas as well as many companies. It provides increased capacity and network traffic management features while reducing network costs. SD-WAN analyzes the traffic and immediately selects the best route for each data packet.
How does SD-WAN work?
SD-WAN works on existing network settings using channel solutions. It works across networks, network communication channels and applications. It gives entrepreneurs the ability to connect branches and centers with built-in internet and cloud capabilities and built-in intelligence. This facilitates locally defined on-site and global software delivery.
A well-defined WAN architecture lacks many advantages over a traditional WAN. Some of the benefits are:
Use network authority and cloud traffic management between headquarters / company and its subsidiaries.
Regionalization of different branches using hybrid WAN + LAN concepts and network partitions.
The short lead time when building a large wide network must require support and planning ahead of time.
- WAN technology used as a platform for information systems, voice & data technologies.
- WANs connect multiple LANs to each other through a private virtual network (VPN) and then connect more than one location to another.
- WAN relies entirely on Multi-Protocol Signaling (MPLS) to provide efficient network traffic switching. Allows you to download network voice, video and road data traffic.
How does traditional WAN work?
To targeted customers by purchasing and delivering special channels through WAN to direct IP services . To improve the network, we obtained from the hardware. Due to the large number of hardware devices and systems installed to operate the network, the complexity of these types of networks makes IT management a tedious and difficult task.
Providing security in the form of
- IP blocking as well as
- access control lists to prevent bad traffic.
These are handled by related hardware & software vendors.
Creating more branches in remote areas will require additional infrastructure to drive business growth.
Compared to SD-WAN, the traditional WAN version is more powerful. This is because it is necessary to make appropriate preparations in advance and have access to the equipment needed to set up the work.
Differences between WAN vs SD-WAN:
trust and leadership:
In general, custom WAN running MPLS provides high performance (QoS) by avoiding small packet loss. This often goes beyond the circuit connection. One thing to keep in mind is that MPLS bandwidth like this is often expensive.
It is important to determine which high-traffic customers are helping companies keep track of their calls. Traditional WAN technology allows you to take the lead and provide predictable traffic and reliability.
Studies show that using SD-WAN can reduce network costs. This is because you do not have to pay much for bandwidth expansion and the ability to integrate and connect internet connections cost-effectively, depending on the type of content and needs. SD-WAN can run on 4G LTE and broadband internet, which is generally cheaper than the services provided by the MPLS network.
SD-WAN allows you to send the most important data traffic to the best internet connection as well as many quick settings. This leads to little or no privacy and loss of luggage.
WANs will provide high security. For MPLS connection, it sends package confidentially. It is only visible on the required MPLS connection. Which allows secure communication from one location to another.
SD-WAN protects data traffic by providing end-to-end encryption over a virtual network (VPN) connection. This technology allows additional security features, such as firewalls and quickly integrated for unified music management.
Care and change:
If you want to switch to a custom WAN, you need to do it manually. This can take a long time and reduce the efficiency of a growing company – especially a company expanding their branches.
As a software solution, SD-WAN can be extended rapidly as your business grows, especially when you are interacting with a service provider.
Both the WAN and SD-WAN standards have physical connections, but SD-WANs have virtual hardware that is removed from the top of the physical connection. This virtual SD-WAN connection can be changed quickly from device to device or changed quickly depending on business needs.
Because applications require more bandwidth, SD-WANs can be scaled to fit seamlessly across protocols. For WAN standards, this is usually a manual program when modifications are required.
