Overlay VPNs and Gluon

Introduction

The overlay VPN project will seek to build out a simpler, lightweight implementation of MPLS based BGP-VPNs using SDN principles. Customer IP packets (L3VPN) or Ethernet frames (EVPN) will be isolated from each other using MPLS VPN labels and separate VRF lookups. The well-known control plane for BGP-VPNs will interface with a high-performance, highly scalable ONOS cluster, to program hypervisor switch VRFs for L3 VPNs and EVPNs. With the use of BGP, the ONOS controlled racks will interwork with racks controlled by other vendor solutions for overlays (eg. Cisco, Juniper, Ericsson and Nokia), as well as any hardware WAN gateway (see Fig. 1). On the northbound side, all SDN based solutions will interact with OpenStack using the Gluon framework.
