In the digital age, businesses depend on reliable network connections. Traditional failover mechanisms, based on a simple up/down status, are no longer enough. Wanscale introduces Telemetry Based Routing, a smarter approach to network control using real-time data and application-aware routing.
Smart failover
Traditional failover mechanisms typically operate using simple logic: they send test packets over the connection at regular intervals, using methods like ping or HTTP requests. If these test packets are successfully received, the connection is considered “up.” If not, the system triggers a failover to an alternative connection.
In theory, this sounds like a solid approach. But in practice, the system is overly simplistic and lacks critical nuance.
Imagine a scenario where a connection is experiencing 40% packet loss. This means nearly half of all data packets are being lost in transit. However, there’s still a chance that the few test packets sent by the monitoring tool make it through. The result? The system concludes that the connection is healthy and continues to use it.
Meanwhile, users experience something entirely different:
- VoIP calls stutter or drop
- VPN sessions freeze or slow down drastically
- Cloud applications respond slowly or not at all
In short: the line is technically “up,” but in reality, it’s not functioning properly. The failover isn’t triggered because traditional monitoring tools don’t “see” the problem. This creates a false sense of availability, leading to frustration, loss of productivity, and potentially even business-critical disruptions.
This is exactly why a modern, data-driven approach like Telemetry Based Routing is essential in today’s network environments. Instead of relying on snapshots in time, this approach looks at the overall behavior of the connection over time, including packet loss, latency, and jitter and responds intelligently.
Wanscale delivers real-time insight
Wanscale continuously monitors connections based on quality, not just reachability. By analyzing packet loss, latency, and jitter through statistical averaging, it provides an accurate view of the actual state of the connection. Additionally, Wanscale uses multiple connection statuses such as UP, DEGRADED, DOWN, and FLAPPING, enabling a more nuanced and intelligent response.
What is Telemetry Based Routing?
Telemetry Based Routing is an intelligent routing technique in which real-time network data automatically determines which traffic is sent over which connection. Wanscale applies this method based on both the quality of the connection and the type of application traffic.
For example: when a connection is marked as DEGRADED, our platform can continue to route non-critical traffic, such as updates or social media, over that link. Meanwhile, critical applications like VoIP, video conferencing, or ERP are automatically rerouted over a more stable alternative.
Stay online, no matter what
The strength of Wanscale lies in the combination of continuous monitoring, intelligent interpretation of network behavior, and dynamic, telemetry-based routing. Instead of an all-or-nothing approach, the platform offers flexibility and control, keeping your organization online at all times. Reliable, efficient, and focused on what truly matters.
