A method, system, and computer-readable storage device for detecting conflicts in a hybrid network device is described herein. A hybrid network device may receive a local controller command from a network management device (e.g., a laptop, operated by a network administrator, executing a command line interface). The hybrid network device may convert the local controller command to a software defined command format. The hybrid network device may detect a lack of conflict between the converted local controller command and active flows represented in an active flow repository. Based on the detected lack of conflict, the hybrid network device may update a traffic forwarding table of the hybrid network device in accordance to the local controller command.

Conflict detection in a hybrid network device

Flow activity is measured on a network device which may be OpenFlow-enabled. A hardware table on the network device, wherein the hardware table includes a record for each flow entry and a hit bit corresponding to each flow entry, is polled for determining status of the hit bit corresponding to each flow entry. An activity measure is updated with the status of the hit bit corresponding to each flow entry.
