These policy and priority handling enhancements will be explored in more detail.
Implementation notes (order of deliverables):
1) NIM should produce NITS (Network Instance Test Status) based on IP being available on ports. NIM should also respond to any changes to ports/IP addresses (UP/DOWN/Address change) and pick one from the ports available to network instance. In this phase, NIM only checks if there is an IP address assigned to port and would deem it usable if it does have one assigned. NITS status should have network instance and the port name that should be used for sending out traffic.
Zedrouter should then respond to NITS and re-configure/program NAT rules, port map rules etc corresponding to applications attached to the network instance.
2) Enhance NITS test to use Zedcloud ping to find any remote network failures.
3) Assign priorities to ports and produce NITS results based on priorities. Free port flag that is present currently will be replaced with priority relative to other ports. NITS should give the highest working port for a given network instance.
4) Network instances should allow user to configure a test target URL/IP address along with test timer interval. EVE device instead of using the default Zedcloud ping, will use the configured test URL/IP to test if a given port can be used.
