QC – Qwilt Cloud Service Controller
A control function used by the delegating Content Publisher that enables them to identify Qwilt Edge Cloud resources available within a service provider network. QC provides a set of APIs to the Publishers while representing the entire service provider distribution network realm, tracking all of the Qwilt Node locations, status, capabilities and subscriber mapping.
QN – Qwilt Node
Universal caching software that includes open caching node functionality deployed and owned by the service provider in close proximity to the users. A typical Tier 1 service provider realm may employ multiple QNs (100s-1000s). The primary goal of QN is to deliver content to users within the service provider realm while relaying logging and billing information to the Content Publisher that delegated traffic to it.
The Qwilt Cloud API exposes the service provider footprint (as specified by the service provider) to a Content Publisher. The Publisher chooses whether or not to delegate content delivery to the service provider network based on the client’s location. Once delegated, the Qwilt Edge Cloud routes the client to the optimal Open Caching Node.
