MEDIA ACCESS CONTROL ADDRESS KEEP-ALIVE DEVICE AND METHOD FOR CONVERGENCE PORT

摘要

The present invention discloses a Media Access Control (MAC) address keep-alive device and a method for a convergence port. In a MAC address aging period, a subsystem receiving message sends an MAC keep-alive message to a global convergence port MAC address management module. Then the global convergence port MAC address management module sends the received MAC keep-alive message to all subsystems to keep the MAC address alive. The device and the method of the present invention can keep the MAC address of the convergence port alive in the MAC address aging period, effectively avoid flooding of destination message on two-layer network equipment due to error deletion of the MAC address of the convergence port, and effectively save the occupancy rate of a network bandwidth.
