The Qwilt Advantage
Our customers benefit from Qwilt’s exclusive product features:
Qwilt’s Video Fabric Controller is architected with the operator needs in mind, featuring the most seamless network insertion possible – the solution is entirely out-of-band and outside the main data connection flow. This approach ensures true “five nine” reliability and 24/7 network continuity, without costly upgrades, complex configurations, or introducing a point of failure or latency into the network.
What Inline Deployment Really Means
Legacy caching systems typically require at least one device to be deployed in the path of the live traffic. This approach introduces numerous points of failure and adds latency to network traffic.
Whether using an external DPI device or relying on complex PBR configurations, inline solutions require extensive network reconfigurations and additional costly equipment purchases. While legacy caching solutions may reduce transit costs, the savings are typically offset by the purchasing, deployment, and management overhead of additional devices required to maintain capacity.
In this example, the seemingly innocuous deployment layout doubled the amount of non-cacheable traffic classification required of the DPI device, pushing it beyond originally planned capacity and significantly slowing down network performance for subscribers. In order to keep the network operational, the service provider is forced to purchase and deploy additional DPI equipment, further increasing the total solution and ownership costs and increasing the footprint. Good news for DPI vendors, bad news for network operators.
|Qwilt’s QB-Series||Legacy/Inline Solutions|
|Non-Intrusive Deployment||Completely out of band: no bump in the wire, reconfiguration, or additional equipment.||Introduces points of failure, requires extensive re-configuration and costly equipment purchases.|
|Latency||Qwilt’s QB-Series is deployed out-of-band and does not introduce latency into the network.||‘Bump in the wire’ adds latency to both cacheable and non-cacheable traffic (i.e. VoIP gaming, etc.).|
|High Availability||In an unlikely event of a device failure, traffic continues unaffected as the solution is not on the data path.||Complex redundancy schemes resulting in service being interrupted, slowed or lost completely in an event of an inline device malfunction.|
|Unified Solution||No additional CAPEX or supplementary devices – all required functionality is in a single unified platform.||Typically requires costly equipment purchases such as load balancers, storage, switches and DPI gear.|
|Scalability||Built for scale – each node is self-sufficient allowing for simple, immediate, and predictable scalability.||Subject to limitations of disparate products, typically pushing DPI devices beyond their planned capacity.|
|Edge Deployment||Edge deployment ready – compact all-in-one form factor with an out-of-band insertion model.||Unsuitable for edge deployments due to large solution footprint, complexity, and cost.|
