SD-WAN for Mission-Critical Applications - Lanner Electronics | Network Appliance | uCPE SD-WAN| MEC Server | Intelligent Edge Appliance

Times have changed, and global enterprises now face the unprecedented challenges necessitated by Cloud technology. With AI, cloud computing, IoT devices, and mobile devices changing how services are done and the complex architectures behind them, Perpetual Connectivity has become an indispensable business requirement.

The Hybrid multi-cloud world being inevitable, how to manage manifolds of connections going beyond the traditional network architecture back to the datacentre has prompted the IT teams to move on. Since the existing wired network architecture is being overly taxed by the unstoppably increasing mobility and backhauling the traffic causes latency and crippling the entire connectivity, IT must strive to balance the application delivery, optimizing cloud connectivity while ensuring distribution network security.

It’s essential to realize how SD-WAN as the most advanced WAN option can offer simplification, alleviate the IT pains, maintaining bandwidth efficiency and provide uninterrupted connections to the cloud, particularly for those critical applications like the healthcare services; any unplanned network downtime, after all, can lead to more severe negative impact to patients other than financial and operational loss.

 No More Fear for Network Failovers

As Network Failover completely lies upon the state of the uplink/downlink, sole wired lines are no more enough for backup connectivity and redundancy. In a traditional approach, either adding a new wired connection to a fixed location or through a different entrance could cause risks of disconnections during construction/maintenance and dear installation costs. A wireless failover connection is a more effective and economical solution because it ensures consistency and diversity by providing a physically non-interruptible link. In addition, SD-WAN provides reliability through managing access required for system diagnosis and update/patching. Lanner’s NCR-1510 and endpoints alleviate the need for an onsite IT team by enabling Out-of-Band Management (OOBM). With a direct connection from an LTE adapter’s console port to the primary router at a branch location, network managers can troubleshoot issues remotely and fix problems in time. The Network Bandwidth is also guaranteed during a network failover with Software-Defined WAN (SD-WAN) technologies; through bandwidth aggregation and traffic segmentation between wired and wireless WAN links, SD-WAN allows IT to set configurations that ensure critical data precede the wireless failover link. As a result, all business-critical traffic can continue to flow with higher-bandwidth Gigabit-Class LTE and 5G connections.

No More Sacrificing Security

SD-WAN allows mission-critical traffic and assets to be partitioned and well-protected against vulnerabilities. In retail or financial verticals, for example, the confidential application traffic within the enterprise is protected from outside threats via SD-WAN’s leveraging diverse security solutions.

The time has come for service providers to adapt to take advantage of the SD-WAN adoption for their own revenues and upcoming changes.   SD-WAN platforms are sure to present a responsive and flexible network solution that stands the inevitable system downtimes while maintaining the quality and security of MPLS.
