Compared with prior art, use the present invention, by sending the ICMP request message to each user, if receive response message at the appointed time, think that then the user is online,, then think user offline if send the several times request message and do not receive when once replying at access server, regain user's IP address, thereby saved the resource of system.
Description of drawings
Fig. 1 is the flow chart that inserts user's IP keepalive method in the specific embodiment of the invention;
Fig. 2 is the structural representation of a kind of access server in the specific embodiment of the invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
The main design of the access user's based on the DHCP agreement of the present invention IP keepalive method is; access server sends request message to each user; if receive replying that the user replys at the appointed time; then keep this user's IP address; if when access server sends the several times request message and does not receive replying that the user replys; then think user offline, regain user's IP address, thereby saved the resource of system.
As shown in Figure 1, a kind of IP keepalive method that inserts the user, this method specifically may further comprise the steps based on the DHCP agreement:
Wherein n is the integer greater than 0.
The time of timer can dispose.
Whether step 140, access server receive the ICMP response message that the user replys at the appointed time, if then keep this user's IP address; Otherwise, execution in step 150;
If receive user's ICMP response message in access server is judged at the appointed time, then this user is online.
Fixed time can dispose.
The max-timeout number of times can dispose.
This moment, access server was after the user sends the ICMP request message, do not receive the ICMP response message that the user replys, then think this user offline, regain this user's IP address, this user profile of deletion in the user management tabulation, return step 120, whether access server detects next user online.
As shown in Figure 2, a kind of access server based on the DHCP agreement, comprises user management list block, IP keep-alive module, wherein,
The user management list block is used for after making user terminal obtain the IP address by the DHCP agreement, adds this user profile in user management tabulation, and the user management tabulation is offered the IP keep-alive module inquires about;
The IP keep-alive module is used to start timer, regularly travels through the user management tabulation, by the ICMP agreement, sends the ICMP request message to the user on time; If receive the ICMP response message that the user replys at the appointed time, then keep this user's IP address; If when the number of times that sends the ICMP request message to the user reaches the max-timeout number of times, and when not receiving the ICMP response message that the user replys, then regain this user's IP address, and the user management list block is sent message, this user profile of deletion in the user management tabulation.
The invention will be further described below in conjunction with instantiation.
The present invention includes following handling process:
Step 210, user's request are reached the standard grade, and obtain the IP address by the DHCP agreement;
Step 220, user are after access server is reached the standard grade success, and access server adds this user profile in the user management tabulation;
Step 230, access server start timer, regularly travel through the user in the user management tabulation, revise each user's detection time, when user's detection time arrives, user profile by in the user management tabulation sends ICMP Request message to the user;
Step 240, before ICMP Request (request) message is overtime, if receive ICMP Reply (replying) message that the user returns, represent that then the user is online, this moment, the user's detection time of resetting was a default value.If do not receive user answer, judge whether the user reaches the max-timeout number of times earlier, if do not exceed the max-timeout number of times, then continue to send ICMP Request message to the user, otherwise think that this user goes offline, then be recoverable to this IP address, delete this user profile.
Top step all is order with time, dependence is successively arranged, because this scheme realizes the user's online detection by the ICMP agreement, so client can not abandon the ICMP request message that access server sends over, otherwise when access server can not be received user's ICMP response message in maximum times, then can think this user offline, user's detection time at interval in addition, time-out time and max-timeout number of times all can dispose, so can use this function flexibly.
