METHOD FOR PROPAGATING MOVEMENT EVENT MESSAGE OF NETWORK ENTITY

摘要

The present invention provides a method for propagating a movement event message of a network entity, including: step 1) a network device maintaining a historical forwarded information list, wherein a network device capable of receiving a movement event message from an external system or device also maintains an uplink port information table; step 2) after receiving the movement event message sent by the external system or device, the network device with the uplink port information table performing matching by using the uplink port information table to obtain a forwarding port and forwarding information of the movement event message, and constructing a movement event forwarding message by using the forwarding information and forwarding same through the forwarding port; and step 3) after a network device receives the movement event forwarding message, searching for a matching forwarding port and forwarding information of the movement event forwarding message in the historical forwarded information list, modifying the movement event forwarding message by using the forwarding information, and then forwarding the modified movement event forwarding message through the forwarding port. The method of the present invention is able to propagate a movement event message to a network device responsible for related data transmission and forwarding.
