Introduction¶
The nmeta (pronounced en-meta) project is founded on the belief that innovation in networks requires a foundation layer of knowledge about both the participants and their types of conversation.
Today, networks generally have only a limited view of participants and conversation types
The goal of the nmeta project is to produce network metadata enriched with participant identities and conversation types to provide a foundation for innovation in networking.
The production of enriched network metadata requires policy-based control, and ability to adapt to new purposes through extensibility.
Enriched network metadata has a number of uses, including classifying flows for QoS, billing, traffic engineering, troubleshooting and security.
Nmeta is a research platform for traffic classification on Software Defined Networking (SDN). It runs on top of the Ryu SDN controller (see: http://osrg.github.io/ryu/).
Limitations¶
Nmeta does not scale well. Every new flow has a processing overhead, and this workload cannot be scaled horizontally on the controller. The nmeta2 system is being developed to address this limitation.
Privacy Considerations¶
Collecting network metadata brings with it ethical and legal considerations around privacy. Please ensure that you have permission to monitor traffic before deploying this software.
