The importance of Network Emulation in testing SD-WAN

To ensure optimal application performance ‘quality of service’ is always a critical factor for applications as users expect the same high performing experience regardless of location.

Applications must be continuously tested under real-world network conditions by being subjected to impairments such as latency, jitter and packet loss to understand the end-user experience. Using the JAR:Emulate network emulator you can test the network adding real-world impairments and discover how applications will perform under a specific set of conditions.

Using our flexible UI you can visually build networks, using the drag and drop functionality to select impairments from the extensive list to create a network map. Network managers and architects can rely on the JAR:Emulate product range to validate SD-WAN performance.

In an increasingly digital world software-defined wide-area network (SD-WAN) is an effective network solution for operating multiple connection types such as MPLS, Internet, LTE, etc. for enterprise networks separated by distance such as data centres and branch offices.

SD-WAN not only minimizes the management of varying connections but is also much more cost-effective than legacy WAN architecture. According to Gartner “SD-WAN can reduce operating time by 75% compared to traditional branch routers.”

Today enterprises greatly rely on wide-area networks to support cloud-based applications with high bandwidth requirements, need reliability and quality to meet business needs.

The inability to maintain clock synchronization under heavy traffic loading increases the chances of failed call setups, failed handover, data re-transmission (leading to slow download and uploads) – in essence poor user experience of the network service.
