This use case aims to show SONATA's ability to monitor, classify, and optimize IoT network traffic. A set of classification VNFs will be deployed at the edge of the network to identify each type of IoT flow. Each different flow will be classified and redirected to an IoT gateway at a local datacenter, where optimizations are performed specific to the type of flow (e.g. transmitting media, or batching requests). The gateway will pass the optimized traffic to the target end system, both reducing the network congestion as well as the load on the central components. The SONATA network will be able to deploy new classifiers where they are needed, scale, and appropriately locate each kind of IoT Gateway to ensure compliance with SLAs, as well as upgrade components with zero downtime to the service.
