We live in a world obsessed with speed and reliability. Whether it’s streaming our favorite shows, conducting mission-critical business operations, or simply browsing the web, we demand seamless connectivity. This has led to the rise of many SD-WAN and router providers touting multipath solutions – the promise of using multiple network paths simultaneously to boost performance and ensure resilience.
Not all multipath is equal, or even located in the same places
But let’s be honest, not all multipaths are created equal. You might think you’re leveraging the full potential of your network with traditional gateway-level load balancing, and while that’s a good starting point, it’s only scratching the surface.
To truly unlock the power of multipath, you need something more, something revolutionary: the Deflection Cloud from Dispersive. Figure 1 below depicts the benefits of applying multipath using the Dispersive deflection cloud at various pop locations vs the traditional SD-WAN VPN point to point approach. Optimizing traffic in the middle has a more dramatic effect on typical performance due to ISP oversubscription at peering points.

Think of traditional gateway load balancing as having multiple lanes on a highway, but all the traffic decisions are made at the on-ramp. The gateway decides which lane each car takes based on pre-defined rules or simple metrics. While this can distribute traffic and offer some redundancy, it’s inherently limited. You need a capability of Distributing traffic in the middle of the internet (at intersections that are optimized).
Why gateway-level load balancing alone falls short:
- Limited Real-time Adaptability: Gateways typically make routing decisions based on static configurations or coarse-grained, aggregated metrics. They lack granular, real-time visibility into individual path conditions like latency, jitter, and packet loss of paths outside their “normal” routes. If one
