In embodiments of the present invention, user data mainly refers to the data of current online wireless user, such as, can include but not limited to: the IP address that the MAC Address of wireless user, the IP address of wireless user, the title of wireless user, wireless user belong to the MAC of AP, wireless user belongs to AP, wireless user belong to the MAC Address and IP address etc. of the AC that AP accesses.Wherein, the data of each wireless user form a user data.In embodiments of the present invention, AC stores multiple user data, also store the current data being in the wireless user of off-line state in addition.In various embodiments of the present invention, mainly pay close attention to the synchronous of the data of online wireless user.
The flow chart of the user data synchronization method that Fig. 1 provides for one embodiment of the invention.As shown in Figure 1, the method for the present embodiment comprises:
Step 101, Network Management Equipment receive the Notification of Changes that AC sends, and described Notification of Changes is for informing that the user data on Network Management Equipment AC there occurs change.
Step 102, Network Management Equipment are according to Notification of Changes, and obtain delta data from AC, described delta data comprises the changed content in the user data changed.
Step 103, Network Management Equipment upgrade the local user data corresponding with AC according to the delta data obtained.
In embodiments of the present invention, delta data comprises the changed content in the user data that AC changes, and this changed content can be newly-increased content, any one or its combination in any in the content of deletion and the content revised.Illustrate, newly-increased content can be wireless user when initial access AP, the information such as MAC Address, IP address of the wireless user of increase, but be not limited thereto.The content of deleting can be that wireless user disconnects, and deletes the information such as MAC Address, IP address of the MAC Address of this wireless user, IP address, affiliated AP, but is not limited thereto.The content of amendment can be the title, IP address etc. of wireless user, such as user needs just to need amendment title, IP address when changing title, IP address, again such as after wireless user is switched to another AP from an AP, need the MAC Address, IP address etc. of changing AP belonging to this wireless user, but be not limited thereto.
Illustrate at this, the delta data of the embodiment of the present invention can be exactly the changed content in the user data changed in realization.In addition, the delta data of the present embodiment can also be the user data changed, and namely comprises the full content of the user data changed.
In the present embodiment, the user data on AC there occurs change and comprises wherein one or more user data and there occurs change.
Concrete, AC, by sending Notification of Changes to Network Management Equipment, informs that the user data on Network Management Equipment AC there occurs change; Network Management Equipment can know that the user data on AC there occurs change after receiving the Notification of Changes of AC transmission; Then, Network Management Equipment initiatively goes AC obtains delta data, and upgrades the local user data corresponding with AC according to the delta data got.Wherein, Network Management Equipment stores the user data on one or more AC, after Network Management Equipment receives the Notification of Changes of an AC transmission, can determine according to information such as the IP addresses of this AC carried in Notification of Changes the AC needing the user data place upgraded, and then get after delta data according to the user data that the delta data got goes renewal corresponding with this AC from this AC.Wherein, corresponding with AC on Network Management Equipment user data refers to the user data on this AC that Network Management Equipment is synchronized to.Concrete, Network Management Equipment only need upgrade the local user data that be stored in Network Management Equipment on corresponding with the user data that AC changes according to delta data.
In the prior art, AC often finds a user data changed, and the changed content in the user data just this changed by a Trap message sends to Network Management Equipment, due to send be changed content therefore AC can not store this changed content, in addition, because the SNMP used between AC and Network Management Equipment is a kind of technology based on UDP, only be concerned about and send and be indifferent to opposite end and whether successfully receive, if so a large number of users data change at one time and just there will be AC and send a large amount of Trap message and Network Management Equipment needs to receive at one time the situation of a large amount of Trap message, if these Trap messages will be dropped beyond after the disposal ability of Network Management Equipment, and then cause to upgrade relative users data according to the changed content in the Trap message be dropped and cause the user data on Network Management Equipment and the inconsistent problem of the user data on AC.
In the present embodiment, what AC sent to Network Management Equipment is Notification of Changes, and notice Network Management Equipment initiatively obtains delta data, instead of directly the changed content in the user data changed is sent to Network Management Equipment, therefore can preserve delta data; And Network Management Equipment initiatively obtains delta data from AC, not by the control of AC, the disposal ability of self can be taken into full account, such as go AC to obtain delta data when its own processing capabilities allows, and the problem that delta data will be caused to be dropped because disposal ability does not allow, solve in prior art because the Trap message carrying changed content is dropped the problem inconsistent with the data of the wireless user on AC caused on Network Management Equipment.
Further illustrate, even if AC have sent a large amount of Notification of Changes simultaneously, these Notifications of Changes abandon because causing beyond the disposal ability of Network Management Equipment, but therefore can not cause abandoning of delta data, as long as and Network Management Equipment receives wherein part Notification of Changes just can know that the user data on AC there occurs change, and then can initiatively go AC obtains delta data, complete the renewal to this locality user data corresponding with AC, realization is consistent with the user data on AC.
In addition, in the prior art, if Network Management Equipment is because of some reason, such as safeguard etc., and disconnect network and connect, what now also cannot be able to realize with the user data on AC because of can not receive Trap message that AC sends is synchronous, and that also can cause with the user data on AC is inconsistent.And in the present embodiment, AC meeting storage change data, even if Network Management Equipment because of suspension do not receive AC send Notification of Changes, also the loss of delta data can not be caused, and the Notification of Changes that Network Management Equipment can send according to AC removes to obtain delta data next time, what realize with the user data on AC is synchronous, the user data on maintenance Network Management Equipment on the user data corresponding with AC and AC consistent.
