Method for managing mac address table validity times
The granted patent (Publication Number: US11888741B2) discloses a method for managing a media access control (MAC) address table by a network node. The method involves defining two running times for a timer, specifying validity times for MAC addresses in the table. When a frame is received, the method checks if the MAC address of the source and destination are in the table. Depending on the presence or absence of the destination MAC address, different running times are applied to the timers associated with the source and destination MAC addresses.
Furthermore, the patent includes claims for a non-transitory computer-readable medium storing a program that enables a network-connected device to execute the method described. Additionally, a network node is detailed, comprising a processor and memory with computer program code to define running times for timers, receive frames, detect MAC addresses, and apply running times to timers accordingly. The method aims to efficiently manage MAC address tables by utilizing different running times for timers based on the presence of MAC addresses, ultimately enhancing network performance and resource allocation.
