DIMINET: On Demand Multi-site Connectivity for Edge Infrastructures
summary
DIMINET is a Python service that glues independent OpenStack Neutron instances using the neutron-to-neutron interconnection plugin and BGP-VPNs (GoBGP as the route agent) to create on-demand L2 extensions and L3 logical routers across sites. It implements a per-resource master to avoid consensus, splits IP allocation pools for remote sites, and only shares necessary metadata. A Grid’5000 proof-of-concept with 21 sites shows resources instantiate correctly; most delay comes from Neutron API calls and a mysterious ~200 ms per-site increase that is being optimized.
