Abstract
The invention relates to a network countdown accurate-synchronization technology. A principle for realizing the accurate displaying of network transmission countdown by using the technology is that: 1) the 'network countdown accurate-synchronization technology' belongs to the technical field of computer network communication, and a server transmits a unified countdown numerical value to clients in a broadcasting way by utilizing a transmission control protocol/Internet protocol (TCP/IP); 2) the clients establish communication channels with the server, monitor local time data and reports the local time data to the server; and 3) the clients receive the broadcast of the server, compute network time delay according to the contents of communication data packets and local time, and obtain the countdown numerical value with millisecond accuracy. The technology is used for various application systems required to use accurate countdown in the Internet and local area networks. For example, when the countdown is required by online transaction systems of online auction, electronic commerce group purchasing and electronic commerce, the server broadcasts countdown data, and the clients accurately synchronously display the countdown data to make the application system fairer and more balanced and avoid legal disputes caused by inaccurate countdown.
Description
One, technical field:
Present technique belongs to the computer network communication technology field, utilizes bottom mechanics of communication Socket, the TCP/IP view in the computer network communication technology, by a series of method, realizes:
1, the unified broadcasting of server countdown data message, client computer receives the countdown data message by the Socket pipeline, and outputs to the terminal output equipment, as display etc.
2, client computer is by after receiving the countdown data message, by analyzing communication data packets, check this machine of client computer temporal information, adjusting a series of processing such as computing network communication time-delay, the countdown data message of data base calibration server broadcasting.
3, the countdown data message of the final output of client computer is realized precise synchronization output with the data message of server broadcast, and all client computer are all exported this countdown data message synchronously.
4, between the different client computer, the data error between client computer and the server is in the millisecond rank.
Two, background technology:
The realization of present technique is a time precise synchronization technology in a kind of network communication of developing of the TCP/IP network communication protocol, Socket API communication part, the programming language instruments such as (java) that utilize the computer bottom.Purchase by group in network auction, ecommerce, in the ecommerce online transaction, when need carry out countdown to certain operation, server is to the Web broadcast countdown time, client utilizes present technique to show the countdown time, make this application system more fair, more just, avoid the legal dispute problem that causes because of countdown is inaccurate.
The technology that relates to has:
(1) TCP/IP network communication protocol, full name: Transmission Control Protocol/Internet Protocol is the communication protocol of heterogeneous network interconnection, can realize interconnected communication between various heterogeneous networks or the xenogenesis machine by it.
(2) Socket model API communication part.
(3) Java development language.
(4) Adobe Flash/Flex AS development language.
Three, summary of the invention:
Network countdown precise synchronization technology.
(1) client computer is initiated to be connected with the Socket of server, and pipeline connects.
(2) client computer reads local time information, to the local temporal information of server report.The OS Events that client computer monitoring local zone time changes is when the change of non-natural increase takes place in local zone time, once more to the local temporal information of server report.
(3) server reads according to the countdown data that produce in the practical business running, sends broadcast message to all client computer, the temporal information when subsidiary temporal information, the server that client computer arranged sends this broadcasting in the broadcast message.
(4) after client computer receives the server broadcast data, according to analysis to packet contents such as the header of TCP/IP packet, messages, and to local time information, server time information, the countdown data message is adjusted in the analysis of computing network transmission time-delayed information.
(5) client computer is finally exported adjusted time data.
(6) when the unit (as: second) of network delay above minimal definition, client computer will stop output this time, directly carry out next round data analysis and output, to avoid the output of invalid data.
Four, description of drawings:
Accompanying drawing is a computer program flow chart of the present invention.Among the figure: 1. flow process is: operation system produces a countdown data message according to actual conditions, reports to server.2. flow process is: client computer is initiated TCP/IP Socket connection request to server.3. flow process is: the connection request of server customer in response machine, set up the Socket connecting tube.4. flow process is: the Socket connecting tube of client computer by setting up with server, and in time monitor local time information and report this information to server.5. flow process is: server is to Web broadcast countdown data message.6. flow process is: client computer receives the broadcast message of server, after calculating, the accurate countdown data of adjustment, and the output result.
Five, embodiment:
(1) preparation:
(1) software distribution package of acquisition present technique: server end broadcast packages, client software bag.
(2) in server system software, quote, comprise the server end broadcast packages; In client machine system software, quote, comprise the client software bag.
(3) in the exploitation of software systems, the api interface method that invoking server end broadcast packages, client software bag provide.
(2) server system software development:
(5) exploitation server service treatment system is used Socket API to set up with the long of client computer and is connected.
(6) data of subscribing client transmission, when the first byte of the binary data packets that sends when client computer is 0x08, the data of this packet are the local zone time data of client computer, obtain the local zone time data, the SetRemoteTime of invoking server end broadcast packages (Socket remote) method.
(7) when service needed broadcasting countdown, the time numerical value that operation system calculates countdown calls: SendCountdown (traffic ID, time numerical value) then.
(3) client machine system software development:
(8) exploitation client computer transaction processing system uses Socket API and server resume length to be connected.
(9) start " changing monitoring " function, that is: call the API:StartTimeTask () of client software bag to client computer report local zone time and this machine time.
(10) client computer operation system, monitoring server Socket broadcast data when receiving data, calls the API:long countdown=GetCountdown (Socket remote) of client software bag.The countdown return value is the accurate countdown numerical value of having been handled by present technique.
(11) decision of client computer operation system is exported and is not exported behavior.
