Further embodiment of this invention provides a kind of heartbeat mechanism keeping method, as shown in Figure 2, which comprises
201, when gateway initiates registration request for the first time, the initial heart cycle time is arranged in Softswitch, described
It include registration information IP packet in request.
202, the gateway sends long connection to the Softswitch according to the initial heart cycle time
Packet.
203, the source IP address and port information of the registration information IP packet are connect by the Softswitch with the length
It is compared between the source IP address and port information of packet.
The step 204a that is executed after step 203, in response to comparison result for both it is identical, the Softswitch is based on institute
The initial heart cycle time is stated, heartbeat cycle time is increased to 2T, the T is the initial heart cycle time.
Step 205a, Softswitch iteration execution comparison step and the heart beat cycle adjustment step executed after step 204a
Suddenly.
The step 206a that is executed after step 205a, in response to comparison result for both it is identical, the Softswitch is by the heart
The hop cycle time is increased to nT, and n is positive integer.
The step 207a that is executed after step 206a, in response to comparison result for both it is different, the Softswitch is by the heart
The hop cycle time is reduced to n/2T+n/4T.
After step 203, and from the step 204b that step 204a is executed side by side, in response to comparison result be both it is different,
The Softswitch is based on the initial heart cycle time, heartbeat cycle time is reduced to T/2, the T is described first
Beginning heartbeat cycle time.
Step 205b, Softswitch iteration execution comparison step and the heart beat cycle adjustment step executed after step 204b
Suddenly.
The step 206b that is executed after step 205b, in response to comparison result for both it is different, the Softswitch is by the heart
The hop cycle time is reduced to T/m, and m is positive integer.
The step 207b that is executed after step 206b, in response to comparison result for both it is identical, the Softswitch is by the heart
The hop cycle time is increased to T/m+T/2m.
For the embodiment of the present invention, a kind of tool of heartbeat mechanism is kept between the gateway under Softswitch and NAT
It is as follows that body executes process:
(1) distribution private IP address gateway issues registration information to Softswitch.
(2) address conversion is carried out to IP packet on the NAT device of the gateway first line of a couplet, distributes corresponding share communally
Location: IP packet is transmitted to Softswitch by port numbers pair.
It (3) include the initial period in response message to NAT device returning response information after Softswitch certification passes through
Time T.
(3) response message is transmitted to gateway by NAT device.
(5) when gateway issues long connection packet after timet.
(6) when time T is less than the refresh time of NAT device, NAT device distributed to the public network of gateway according to last time
IP address and port numbers carry out address conversion, and IP packet is transmitted to Softswitch.
(7) after Softswitch receives long connection data, the source IP address of registration information IP packet and long connection packet is compared
And port, the two is identical, shows that time T is less than the refresh time of NAT, Softswitch is fed back to using 2T as cycle time
Gateway.
(8) gateway is when issuing long connection packet after time 2T.
(9a) when time 2T is less than the refresh time of NAT device, NAT device distributed to the public affairs of gateway according to last time
Net IP address and port numbers carry out address conversion, and IP packet is transmitted to Softswitch.
(10) Softswitch compares source IP address and the port that length connection IP Bao Heshang vice-minister connects packet, the two phase
Together, show that time 2T is less than the refresh time of NAT, Softswitch feeds back to gateway using 4T as cycle time.
(11) so analogize, when cycle time is nT, Softswitch compares length connection IP Bao Heshang vice-minister connection
The source IP address of packet and port, the two is not identical, shows that the nT time is greater than the refresh time of NAT, then Softswitch is (n/2T
+ n/4T) it is used as cycle time, feed back to gateway.
(12) gateway is when issuing long connection packet after the time (n/2T+n/4T).
(13) when time (n/2T+n/4T) is greater than the refresh time of NAT device, NAT device is useless according to upper sub-distribution
Public network IP address and port numbers to gateway carry out address conversion, but distribute new public network IP address and port numbers pair,
IP packet is transmitted to Softswitch.
(14) Softswitch compares source IP address and the port that length connection IP Bao Heshang vice-minister connects packet, the two not phase
Together, showing that time (n/2T+n/4T) is greater than the refresh time of NAT, Softswitch assigns (n/2T+n/8T) as cycle time,
Feed back to gateway.
(15) so analogize, find the time span of a refresh time closest to NAT device as cycle time.
(16) if in time in initial period T, Softswitch is with comparing the source IP of registration information IP packet and long connection packet
Location and port, the two is not identical, shows that time T is greater than the refresh time of NAT device, Softswitch is using T/2 as when the period
Between, feed back to gateway.
(17) gateway is when issuing long connection packet after time T/2.
(18) when time T/2 is greater than the refresh time of NAT device, NAT device is useless to be distributed to gateway according to last time and sets
Standby public network IP address and port numbers carry out address conversion, but distribute new public network IP address and port numbers pair, and IP packet is turned
Issue Softswitch.
(19) Softswitch compares source IP address and the port that length connection IP Bao Heshang vice-minister connects packet, the two not phase
Together, show that time T/2 is greater than the refresh time of NAT device, Softswitch feeds back to gateway and set using T/4 as cycle time
It is standby.
(20) so analogize, when cycle time is T/m, Softswitch compares length connection IP Bao Heshang vice-minister connection
The source IP address of packet and port show that the T/m time is less than the refresh time of NAT, then Softswitch is (T/m+ if identical
T/2m it) is used as cycle time, feeds back to gateway；
(21) gateway is when issuing long connection packet after the time (T/m+T/2m).
(22) when time (T/m+T/2m) is less than the refresh time of NAT device, NAT device distributed to gateway according to last time
The public network IP address and port numbers of equipment carry out address conversion, and IP packet is transmitted to Softswitch.
(23) Softswitch compares source IP address and the port that length connection IP Bao Heshang vice-minister connects packet, the two phase
Together, show that (T/m+T/2m) time is less than the refresh time of NAT, then Softswitch assigns (T/m+T/2m+T/4m) as the period
Time feeds back to gateway.
(24) so analogize, find the time span of a refresh time closest to NAT device as cycle time.
Compared with prior art, since each NAT device refresh time is different, each gateway reaches soft friendship
The long connection packet time of exchange device is different, and the embodiment of the present invention can be by the above-mentioned comparison step of iteration and to heart beat cycle
The NAT device refresh time of the long connection cycle time and its first line of a couplet of each gateway may be implemented in the set-up procedure of time
It is closest, the concurrent pressure due to caused by multiple gateway equipment is avoided to realize, to mitigate the data processing of Softswitch
Pressure.
