Embodiment
TCP (Transmission Control Protocol, transmission control protocol) is the transport layer protocol in the ICP/IP protocol stack, can confirm and the bag retransmission mechanism by sequence, provides reliable data flow to send and arrive the virtual Connection Service of application system.TCP is long to be connected and refers to after client and server end set up TCP and is connected, and the transmission message in cycle is safeguarded that this TCP is long and connected and monitor TCP length connection status.This maintenance and monitoring mechanism are also referred to as Hello mechanism, concrete, after the long connection of TCP is set up, side in the connection can be according to the hello packet of certain cycle to the opposing party's transmission, this cycle is called the Hello cycle, after the opposing party who connects receives hello packet, also send a TCP response message and respond.In case the transmit leg of hello packet does not receive the TCP response message in set point number, can judge that then the long connection status of the TCP that has set up breaks down, when the recipient of hello packet does not receive hello packet in setting duration, can judge that also the long connection status of the TCP that has set up breaks down.
Based on this, the embodiment of the invention provides the long interconnection technique of a kind of TCP of utilization to improve the data sync scheme of data sync reliability, can be between the isomery application system when the synchronous application system of request msg can carry out data sync based on Web Service technology, in time initiate data sync again according to the variation of IP address, thereby improve the reliability and the real-time of data sync, be elaborated with specific embodiment and conjunction with figs. below.
As shown in Figure 2, it is example that the embodiment of the invention is carried out data sync with application system B request and application system A, describes the isomery application system method of data synchronization that the embodiment of the invention provides in detail, mainly comprises the steps:
When step S201, application system B carry out data sync at the application system A of needs and isomery, IP address and TCP link slogan according to application system A, initiate to the TCP connectivity port of application system A that TCP is long to connect the request of foundation, and and application system A set up TCP length and be connected;
Step S202, application system A issue the data sync order by long connection of described TCP to application system B;
After step S203, application system B receive described data sync order, dispose data sync port numbers according to the IP address of described application system A and application system A to Data synchronization interface, call Data synchronization interface and application system A carries out data sync based on the WebService technology, to keep both sides' data synchronization;
Step S204, application system B set up the long fault that whether connects of TCP that the back monitoring set up in long connection of TCP, if fault, trigger data is synchronous again then to return step S201.
Like this, when application system B can't keep the long connection of TCP of having set up because of the IP address changes, again initiate the long connection of TCP with new IP address, and restart data sync with new IP address, original data synchronization process stops automatically in response to the IP address change of using the B of system, thereby has improved the reliability and the real-time of data sync between application system A and the application system B.

S301, application system B are according to the predetermined Hello cycle, the regular hello packet that sends to application system A, and whether monitoring receives the TCP response message that application system A returns, if do not receive the TCP response message of set point number, then can judge and break down long connection of TCP, stop to continue to send hello packet and connect so that the TCP that disconnects this is long;
S302, application system A are according to the hello packet of application system B, return the TCP response message and monitor blanking time between the hello packet to application system B, if application system B stops to continue to send hello packet because of judging that the long connection of TCP is broken down, when then application system A does not also receive next hello packet when setting duration arrival, can judge that also the long connection status of the TCP that has set up breaks down.
The reason that can monitor the long connection status of TCP according to Hello mechanism is, when the IP address of application system B changes, the source IP address of hello packet changes, application system A connects based on the TCP that has set up is long, can't resolve the hello packet that sends after application system B changes in the IP address, therefore no longer return the TCP response message to application system B, the long connection of former TCP can't continue to keep.Application system B by Hello mechanism in time know with application system A between the long fault that is connected of the TCP that sets up, TCP is long to be connected to initiate new data sync flow process thereby set up with application system A again timely, can solve the data synchronization problems of the isomery application system in the diverse network structure, and the Business Processing that can be correlated with synchronously.
