Top Six Attributes Needed In A Software-Defined Network
This four-part blog series lays out the evolution from SDN to SD-LAN as well as the benefits of both. Last week I discussed enterprise wired and wireless networks. Today, I will put forth a list of what network decision makers should look for in a software-defined enterprise wired and wireless LAN solution.
Given the importance of LAN and WLAN to enterprise networking initiatives, there is a need for a software-defined solution for the enterprise campus.
Specifically, network decision makers should look for a software-defined enterprise wired and wireless LAN solution that addresses the following:
1) Application optimization. Networks need to be optimized to run the applications most important to the business at full performance and reliability. Similarly, in the age of DX, networks should be able to dynamically adapt to the elastic needs of many applications.
2) Granular security and policy enforcement. With myriad groups of users accessing the network, including employees at all levels of the organization, as well as contractors, guests, and “things,” it is important that security policies can be highly specified based on the user, device, and/or application accessing the network.
6) API compatibility. Because network applications are increasingly integral to business strategy, it is important that a campus network architecture provides open APIs so that applications can be developed natively for the network on which they will run. These applications can serve technical use cases such as network management and monitoring and development of WiFi or LAN as a managed service, or they can be business applications such as those for offering location-based services (LBS), loyalty engagement, or patient and guest check-in, among many other examples. Such applications can help transform the network from a cost center to a profit center.
Long gone are the days of plug-and-play networking. Before the explosion of mobility, apps, and IoT, network management was a alot simpler. Today, we require much more robust solutions. Enter SD-LAN (Software Defined LANs).
