2. Objective
Enable scalable, easily programmable, software defined, overlays
Data-driven control plane
Rich set of address types and forwarding policies
Simple Northbound APIs
Based on open standards

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

9. 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

10. 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
