ARP and NDP FSM Plugin Redesign for Improved Resource Allocation

Design

The NDP plugin combines roles of the previously separated NDP and ARP plugins:

• From an NDP perspective, the plugin reports network activity from specific client devices to the controller, and performs IPv6-to-MAC mapping.

• From an ARP perspective, the plugin collects the ARP data flow information, and

  orchestrates IPv4-to-MAC mapping sources.

Combining these two plugins reduces the footprint of FSM system resources usage:

• One TAP interface

• One pcap socket

Controller Involvement

The following controller changes are required:

• Updated OpenFlow rules to redirect both ARP and NDP traffic to a unique tap interface

• Combined NDP and ARP Flow_Service_Manager_Config entries in a single entry
