OpenConfig is an informal working group that aims to standardize network data models and streaming telemetry through vendor-neutral models written in YANG. It has developed models for BGP configuration, ACLs, and streaming telemetry. OpenConfig data models and transport protocols like gRPC are independent, allowing operators flexibility. The models provide a common interface for both device configuration and obtaining telemetry data. Demonstrations showed retrieving BGP configuration data and modifying settings via a gRPC client, as well as receiving streamed telemetry updates.

• What is OpenConfig?
• OpenConfig is an informal working group of network operators sharing the goal of moving our networks
toward a more dynamic, programmable infrastructure by adopting software-defined networking principles
such as declarative configuration and model-driven management and operations.
• Common data models
• Our initial focus in OpenConfig is on compiling a consistent set of vendor-neutral data models (written in
YANG) based on actual operational needs from use cases and requirements from multiple network
operators.
• Streaming telemetry
• Streaming telemetry is a new paradigm for network monitoring in which data is streamed from devices
continuously with efficient, incremental updates. Operators can subscribe to the specific data items they
need, using OpenConfig data models as the common interface.

• Already model Defined for BGP configuration, operation /ACL and streaming telemetry
• https://github.com/openconfig/public/tree/master/release/models
• Transport and RPC(Remote Procedure Call) Protocol
• Data model, transport and RPC are independent , so can choice any protocol as you like
• NETCONF and REST CONF
• gNMI(gRPC Network Management Interface) which use common gRPC protocol between Telemetry and
Configuraiton.

• Provide common data model which is independent of vendors,
generation for configuration and streaming telemetry
