Charter for Working Group

The IETF and the industry in general is currently specifying a set of YANG models for network element and protocol configuration. This is an essential first step, but the end goal is full system configuration that allows the deployment of services across networks. Services are built from a combination of network element and protocol configuration, but are specified to service users in more abstract terms.

The Layer Three Virtual Private Network Service Model (L3SM) working group is a short-lived WG tasked to create a YANG data model that describes a L3VPN service (a L3VPN service model) that can be used for communication between customers and network operators, and to provide input to automated control and configuration applications.

It needs to be clearly understood that this L3VPN service model is not an L3VPN configuration model. That is, it does not provide details for configuring network elements or protocols. Instead it contains the characteristics of the service, as discussed between the operators and their customers. A separate process is responsible for mapping this service model onto the protocols and network elements depending on how the network operator chooses to realise the service.

The deliverable from this working group will provide information to evaluate the set of YANG models that have already been developed or are under development, and will help identify any missing models or details. The deliverable can be viewed as driving requirements for protocol configuration model so that the service parameters can be mapped into inputs used by the protocol models.

It is hoped that this working group will provide evidence that such service models can be quickly constructed and agreed upon. If successful, further service models may be developed in other working groups

The working group should consider draft-l3vpn-service-yang as a starting point.
