How to create a virtual WAN
Recent industry research shows that virtual WANs are becoming increasingly popular, and will be deployed more often in the coming years. Findings from Rayno Report show that virtual cloud WAN services market will grow to reach $7.5 billion in revenues over the next five years.
As more organizations look to implement and utilize virtual WAN technologies in their infrastructures, it is important that they have a full understanding of how the system works. Creating a virtual WAN includes several additional components that are layered onto WAN nodes, thereby making up a virtual environment in which network traffic travels.
Let’s take a look at what it takes to create a virtual WAN, and how Talari’s intelligent, thinking WAN works in particular.
What is a virtual WAN and what makes it beneficial?
“Virtual WANs are made up of physical or virtual appliances deployed at the WAN nodes as well as management and integration systems.”
In essence, a virtual WAN is a software-defined version of a traditional wide area network system. Peter Christy, director of networking practice at 451 Research, noted that while virtual WANs are all made up of physical or virtual appliances deployed at the WAN nodes as well as management and integration systems, the technology can differ depending on the users’ needs.
“Each virtual WAN is defined by its topology (which nodes are connected), the service requirements (what each use requires), and the security, privacy and the regulatory compliance requirements that apply,” Christy wrote. “Each use can be configured independently, and created or changed on the fly, consistent with the physical underlay of being capable of meeting the requirements and the availability of enough aggregate connection capacity.”
With this construction, virtual WANs are considerably flexible and can be adjusted, moved or changed depending on user demands. This is not the only advantage offered by a virtual WAN system, however. Many adopters flock to the technology due to the network agility it brings to overall network management. Within a virtual WAN, different traffic types can be prioritized to ensure that critical applications always have the support they need. Other Web-based systems are also more easily integrated within a virtual WAN, enabling businesses to create a more unified and streamlined network architecture.
A look at the Talari software defined THINKING WAN solution
Talari’s THINKING WAN solution represents the gold standard in software defined WANs, and empowers the network to adapt to bandwidth needs and changing network conditions in real time. The system utilizes users’ available links to create a more accessible, reliable and available WAN offering the best performance possible.
This virtual WAN solution utilizes an array of available links – including all MPLS, a hybrid system of MPLS and broadband or all Internet links – and backs these up with wireless or cloud extensions. This provides constant network availability, as well as more granular management of traffic.
Through its SD-WAN, Talari is able to measure packet loss, latency, jitter as well as the overall availability of each path within the WAN and to the cloud. It does this for each and every packet traveling in each direction in the system, enabling real-time network insight that allows the Talari solution to select the most optimal path for each packet. This ensures that the network is continually responsive and is constantly providing the best performance depending on current conditions, bandwidth availability and overall demand.
