The IETF and the industry in general is currently specifying a set of YANG models for network element and protocol onfiguration. This is an essential first step, but the end goal is full system configuration that enable service agility to speed service creation and delivery and allows the deployment of innovative new 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 Two Virtual Private Network Service Model (L2SM) working group is a short-lived WG tasked to create a YANG data model that describes a L2VPN service (a L2VPN service model) that can be used for communication between customers and network operators, and to provide input to automated control and configuration applications. The working group will attempt to derive a single data model that includes support for point-to-point Virtual Private Wire Services (VPWS) and multipoint Virtual Private LAN services (VPLS) that use Pseudowires signaled using the Label Distribution Protocol (LDP) and the Border Gateway Protocol (BGP) as described in RFC4761 and RFC6624. It needs to be clearly understood that this L2VPN service model is not an L2VPN configuration model. That is, it does not provide details for configuring network elements or protocols (that work is expected to be carried out in other protocol-specific working groups). Instead, the L2VPN service model 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. The working group will learn from the experience of the L3SM working group and it is expected that the L2SM data model will have similar structure to the L3SM data model. The working group should consider draft-wen-l2sm-l2vpn-service-model as a starting point. The working group will coordinate with other working groups responsible for L2VPN protocol work (most notably with BESS and PALS) and with the MEF.
