Network Working Group Y. Zha Internet Draft Huawei Technologies Intended status: Standard Track D. Zhang Expires: June 2016 Y. Cheng, Ed China Unicom M. Klyus NetCracker December 18, 2015 Layer 3 VPN Service deployment in ONOS draft-zha-l3sm-l3vpn-onos-deployment-03 Abstract This document defines a YANG model that is used to deliver layer 3 VPN service in ONOS project which is on the controller level. L3SM is focused on the service model which is on the orchestration level to help interaction between customers and network operators and also can be input to automated control and configuration applications. ONOS runs as an open source project for fast deployment. Use L3VPN service model defined in L3SM and deploy L3VPN service in ONOS project can be one step further. On the other hand, push real deployment in ONOS back to IETF is also beneficial. Status of this Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Introduction ONOS, Open Networking Operating System, is an open source project that provides a platform for a vendor to build their controller through adding services/applications on top of ONOS. One of the principal motivations of ONOS is to facilitate service deployment, such as VPN service. [L3VPN] in L3SM WG defines a YANG model for layer 3 VPN service to deliver overall service. The description of the L3 service is more focused on the high level, orchestration level, with little information to guide the real configuration. A specific configuration related model that is especially working on controller level is necessary to fulfill the fast VPN provisioning. Zha, et al. Expires June 18, 2016 [Page 2] Internet-Draft L3VPN Deployment in ONOS December 2015 This document introduces YANG [RFC6020] [RFC6021] data models for L3VPN configuration in ONOS. Such models can facilitate the standardization for the interface of ONOS, as they are compatible to a variety of protocols such as NETCONF [RFC6241] and [RESTCONF]. Please note that in the context of ONOS, the term "application" refers to an operational and management applications employed, and possibly implemented, by an operator. 2. Conventions used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. In this document, these words will appear with that interpretation only when in ALL CAPS. Lower case uses of these words are not to be interpreted as carrying [RFC2119] significance. 3. L3VPN Deployment in ONOS In this section, a brief description of ONOS project as well as the L3 VPN deployment demo [ONOS-L3VPN] will be provided and relationship with L3SM will be addressed from an implementer's point of view. 3.1. ONOS-based SDN Controller ONOS is an open source project that allows users to build their own SDN controller on top of it by adding service or applications. Without building everything from scratch, ONOS platform delivers fast and agile service provisioning. First of all, ONOS has abstracted southbound common API allows single controller to control the devices from different vendors. The southbound details with diversified devices and protocols have been masked so as to support multi-vendor environment. Also this enables controller to control both OF and legacy network devices. Secondly, ONOS is architected as logically centralized but physically distributed clustering system. This design aims to offload users' development resource on performance and scalability. Lastly, Services provided by ONOS core are designed and implemented as a set of collaborating subsystems. Network control applications can use those services through the NB API. 3.2. L3VPN Deployment in ONOS-based SDN Controller Deployment of L3VPN in ONOS is based on the requirement that fast and agile VPN provisioning. Using the ONOS given services as collaborating subsystems is the best way to avoid time consuming manual configurations. The overall architecture of L3 VPN deployment in ONOS is shown as figure 1.

A user defined application implemented as an external application running on the top of ONOS. In this project, user provides L3VPN service, PCE (Path Calculation Engine) engine, interface to Portal software, etc. 2. The application keeps a snapshot of global view and network resource availability, which is used by PCE for path calculation in the project. 3. Use Producer-Consumer model to provision VPN. In this P-C model, Producer and Consumer are separate applications. Producer provisions network that for Consumer to use. In this project, Producer provisions MPLS tunnel. Consumer is L3VPN service that uses the tunnel. 4. ONOS core is enhanced with WAN service, such as MPLS Label Manager (support global and local label management), Tunnel Manager, and FlowRule extension. 5. South bound provider allows ONOS to talk with both legacy and OF devices and control both Legacy and OF environment/requirement. Zha, et al. Expires June 18, 2016 [Page 4] Internet-Draft L3VPN Deployment in ONOS December 2015 4. L3VPN Data Model This section is mainly focused on the L3VPN service model as mentioned in pervious section about implementation. 4.1. Design of the Data Model The L3SM is focused on the overall service to propose an abstracted interface to manage configuration of components of a L3VPN service. As shown in the document [L3VPN] section 4, it is service oriented and worked on the orchestration layer which does not specify network configuration. The data model in this document works on controller layer to guide the configuration by utilizing the given services in ONOS Core. The L3VPN service model in [L3VPN] is constructed with two containers, one with some generic VPN information and the other one called site which is composed of a customer edge router (CE) attached to a provider edge router (PE). Meanwhile, the VPN service is sites based and can be treated as connections among multiple sites. However, the L3VPN service in this ONOS project is based on tunnel as mentioned earlier. The L3VPN data model here does not contradict with the one in [L3VPN] since the latter one is working the orchestration level and not designed for specific implementation. Using the [L3VPN] as a reference and use some of its parameters with specific configuration information to design the data model for this deployment in ONOS is primary goal of this document. The YANG model in this document has two containers, one follows the vpn-svc in [L3VPN] to specify the parameter for L3VPN service and utilize the given service, and the latter one is to define the service path which contains ingress/egress information. Note that this configuration model utilizes only part of the parameters defined in the generic service model in [L3VPN] to deploy a VPN service. The key information such as ''connection'', ''qos-policy'', ''connection'', ''protect-policy'' and ''oam-policy'' all come from [L3VPN] The top level design of the data model is shown in the following YANG tree. 4.1.1. VPN service topology The type of topology of the VPN is required for configuration. Current version supports: hub and spoke (where hubs can exchange traffic), full-mesh. New topologies could be added by augmentation. The default service topology is ''full-mesh''. 4.1.2. L3 VPN access information The access information of the VPN contains ''role'' information to denote role of the lsp that it is a master, slave, hub or spoke. Also the qos information is provided with qos policy. Another important container here is the ''connection'' to define the ip connection between PE and CE. Note that [L3VPN] Zha, et al. Expires June 18, 2016 [Page 5] Internet-Draft L3VPN Deployment in ONOS December 2015 has ''ip-connection'' container defined in ''sites'', however the L3 VPN here is not site based so the connection information is defined as general parameters in access information. Following the structure in [L3VPN], the ''connection'' has ip address and the most important thing, ''protocols'' to connect PE and CE, such as OSPF, BGP or static. 4.1.3. Protect policy Protect policy defines the protect type as well as revertive type. 4.1.4. Tunnel service The ''tunnel-service'' is the most important container in vpn-svc. It tells the ONOS core to utilize the tunnel service with information on ''tunnel-mode'' and oam policy. Generally, this is very similar to the ''sites'' container in [L3VPN]. Zha, et al.
