Mapping Service FD.io (VPP) Neutron Service Function Chaining Open Overlay Router

How it is implemented? Key-value Mapping Store with: ODL Longest prefix matching for IP Two tuple key e.g.: (src,dst) -> value Three tuple key (for segmentation) (VNI, src,dst) -> value Data types with native support: IP, MAC, NSH, AS number, Distinguished Name, & more External trigger ODL REST Flow Mapping Service LISP Plugin ODL tracks mappings subscribers and pushes notifications when changes occur. VPP

Internal Architecture Core: Mapping Service In-memory mapping cache layer Supports longest prefix match for IPv4/v6 with segmentation (VNI) Multiple mapping types including JSON and opaque key/value pairs LISP Mapping Service Map Server/Resolver LISP Southbound Plugin LISP control plane messages: Map- Request/Reply/Register Early stages Neutron provider ODL LISP Flow Mapping Service RPC/RESTCONF/GUI Implementation Neutron In-mem Cache Mapping Service Datastore LISP Mapping Service MD-SAL LISP SB Plugin
