Innovating the SD-WAN Network in 2022
March 15, 2022 · Daniel Ayala
SD-WAN networks (software-defined WAN) are becoming one of the favorite technologies in the business environment for all the benefits it entails.
In addition to having a quick implementation, its cloud-based architecture, security in data transmission and low cost make it ideal for companies.
How an SD-WAN network operates
Due to the nature of this network, high availability is offered which will ensure that data transmission reaches its destination efficiently. The process is as follows:
- Data Packet Transmission: The IP data is fragmented and sent from the local network, where the remote site is located, to the CPE.
- Traffic Encryption: The traffic within the VPN is encrypted (AES 256 bits) and sent to each WAN route, depending on how many are available.
- Traffic Decryption: Packets from VPNs are received and decrypted to be sent to the LAN of the central system.
- IP packet assembly: Packets are reassembled by the Hub in the same order that they were sent by the source and received by the server.
SD-WAN the solution for companies
One of the benefits of this technology is its flexibility to operate with different networks such as: cellular, ADSL, WiFI, dedicated internet, MPLS and satellite.
This allows its implementation in companies that already have a network infrastructure without having to discard it, on the contrary, it is integrated and works together.
It is recommended to have more than one network so that the information has more transmission paths (MultiWAN) and thus ensure high availability. An excellent option, due to its low cost and functionality, is the Mobile Cellular Internet, especially with more than one carrier.
Working from the cloud
Regardless of the size of your company, it is essential to have not only a computer network, but also cloud services. All the apps with which your workforce operates can be stored here, thus providing them with the tools for optimal performance.
Due to its wireless nature, it is ideal for implementing sensors IoT both in industry and transportation. The speed of data transmission allows you to manage and view what is happening through security cameras in real time, even operating with a 3G network.
Conclusion
No matter what your business is, considering an SD-WAN network is an excellent idea to boost its performance, security, and reduce costs along the way.
