HA

HA is expanded two ways:

1. high-availability

   HA is a local fault recovery mechanism within a multi-node NSP cluster. HA uses Kubernetes pod replicas to ensure minimal downtime in the event of an essential pod failure within the cluster. HA can be combined with disaster recovery (DR) to provide robust network resiliency and redundancy.

2. home agent

   A router on the home network of an MNN, which tunnels datagrams for delivery to the MNN when it is away from home, and maintains current location (IP address) information for the MNN.
