<p>The present invention provides a method, a service node device and an access node device for keep-alive processing, wherein the method includes: after users access a service node device through an access node device, the service node device sends the access node device the key information of the users whose online statuses change; the service node device receives the information of the offline-user, which is fed back by the access node device by checking a media access control address table; according to the information of the offline-user, the service node device performs keep-alive processing on the users getting access through the access node device. By applying the method, the service node device and the access node device of the present invention, the pressure of the keep-alive processing on the service node device is reduced.</p> |
