Benefits of an SD-LAN network

Better visibility to the network

SD-LAN makes the network’s traffic visible. It tells you what is truly going on in the network in terms of performance, users, applications and devices. The data gives you new insights on the environment and users that support your business. The observational capacity also brings security all around the company’s network.

Integrated data security

Modern data security is comprehensive, and all infrastructure participates in building it. Software-defined LAN technology is secure, and its better visibility help you detect network threats instantly and act fast. You can react quickly to malware and exclude specific devices from the network, for example.

Quick troubleshooting

SD-LAN gathers data related to the network from different sources. By using machine learning, the network analyses the collected data proactively, identifying correlations and deviations. On this basis, the network can help predict faults and produce instructions to support operation. Troubleshooting is thus quicker than before.

Automation helps work

In an SD-LAN network, network devices are configured centrally. This reduces the number of mistakes from manual work in configuring the network devices. System updates are also centralised and scheduled on an SD-LAN. Automation facilitates the work of ICT personnel and keeps the network up to date.

Easy management

In SD-LAN, the management of users, applications and rights is simple. All the terminal devices to be connected in the network are identified, and based on their identity, they are given rights to use the network’s services. You can thus control access rights so that only certain people have access to certain devices.

How does the modern, software-defined local area network work?

Elisa’s SD-LAN is based on network technology from the world’s top producers, which is in accordance with Gartner’s IBNS (intent-based networking system) model. IBNS is not a product or market area, but technology in which the user policy defined by the administrator is introduced in the network’s devices in a software-defined manner. It brings simplicity, automation and insight to both wireless and fixed local area networks.

In traditional local area networks, user segmentation and its definition on network devices typically have the highest workloads, both in the implementation and operation stages. SD-LAN brings segmentation to a new level and makes related planning, definition and use significantly easier. For example, in the case of 100 locations and ten user segments, the workload is reduced to one hundredth of what it would normally be.

SD-LAN also simplifies the wide area network (WAN) structure. Traditionally, user segmentation has been achieved over WAN using multiple VPNs, for example. In our new local area network service, you only need one segment. The technology under the service takes care of end-user segmentation after it.
