MPLS intents and label management
NIC's mapping service should make the creation of intents between two endpoints to be handled by the OpenFlow renderer possible. Thus, this renderer can generate OpenFlow rules for push or pop labels to the MPLS endpoint nodes. After an IPv4 Prefix match and forward to port rule once MPLS label match, all the switches that form the shortest path between the endpoints using the Dijkstra algorithm.
Getting ready
Some constraints were added to the intent model for protection and failover mechanism to ensure end-to-end connectivity between endpoints. These constraints aim to reduce the risk of connectivity failure due to a single link or port-down event on a forwarding device. The constraints implemented are:
- Protection constraint: Requires an end-to-end connectivity to be protected by providing redundant paths
- Failover: Uses disjoint path calculation algorithms such as Suurballe to provide alternate end-to-end routes
- Fast-reroute: Uses failure detection features...
