Embodiment
The invention will be further described in conjunction with embodiment for the contrast accompanying drawing below.
Shown in Fig. 1,3, the communication system of the http protocol of the specific embodiment of the invention comprises WAP server end (WAP site), terminal, WAP gateway; Comprise HTTP module and WAP application end in the WAP gateway, wherein the HTTP module comprises master control thread, message queue, link pond, worker thread.Worker thread is one or more, the corresponding management of each worker thread one link pond.Message queue can be one, also can be for a plurality of; For a plurality of message queues, each message queue has different message attributes, this message attributes can be carried out different settings according to different needs, type that for example can requested service, and for example type of service may be that the difference of video, audio frequency or data service is distinguished.
System architecture is not a stationary, but may carry out dynamic change with actual conditions, for example during system initialization, the master control thread may only be created a message queue, the link pond of a worker thread and corresponding management thereof, along with the increase of linking request number, and create the more work thread thereupon and link the pond to adapt to the needs of real system carrying.
Above-mentioned message, usually can be understood as request, for example in the PULL business, terminal to certain certain business of WAP site request, is at first set up link between terminal and the WAP application end by the HTTP module of WAP gateway by WAP gateway, the HTTP module is according to request, setting up the link of the WAP application end and the WAP site of asking, thus, is transfer with the WAP application end, under the control of HTTP module, terminal and the success of WAP server end link setup.In the PUSH business, may no longer include the request of terminal, and may select different terminals to carry out issuing message by the WAP server end.
The server end address that generally comprises link in the message, information such as requested service type, it is stored in the message queue by the master control thread, possible set-up mode is: a plurality of message queues that different messages attribute (for example aforementioned distinguish with the requested service type) is set, the master control thread with different message deposits in the message queue of corresponding attribute, these message queues are all corresponding at least one worker thread, and worker thread receives message from its corresponding message queue.Another kind of mode: in message queue, do not distinguish, and carry out this processing by worker thread, for example regularly query messages formation of worker thread receives the message that is provided with in the message queue by the message attributes of its processing, has finished the differentiating and processing to the different messages attribute message equally.
Said process can be described as message interaction process, to distinguish mutually with following data transmit-receive process.Worker thread is after obtaining message, link corresponding in the message is put in the link pond of its corresponding management, like this, may comprise multilink in the link pond, i.e. link set, worker thread adopts the SELECT function to be blocked on the link set in link pond in the obstruction mode, whether the SELCET function has data to receive and dispatch to all link checks in the link set, after in case the SELECT function returns and receives data, then rescan the link in the link pond, and join in the link set once more, thereby by the link of worker thread to selecting, also being that WAP server end and terminal room (see through the transfer of WAP application end, so also can think WAP application end and WAP server end or terminal room) are actual has the link of data transmit-receive request to finish data transmit-receive.
In sum, the main setting of communication system of the present invention is:
● no longer include the coupling between internal memory between master control thread and the worker thread, but adopt the master control process to send a message to each worker thread by message queue.The master control thread is put into message queue with message, and each worker thread gets off message sink from message queue, and the message corresponding link is put in the link pond, thereby has avoided the conflict in action link pond simultaneously of worker thread and master control thread.
● the processing of worker thread is divided into two parts, and first half mainly is to receive message from message queue, and link wherein is stored in the link pond, if there is not message just to return immediately, no longer receives the content of message queue, and carries out follow-up processing.Latter half is to adopt the SELECT mode to be blocked on the link set in link pond, and after being provided with overtime 100 milliseconds, time-out time is not limited thereto certainly, also can be according to the corresponding adjustment of actual conditions.If without any socket (two programs are carried out the end points of communication) data transmit-receive is arranged in the set, after overtime, return immediately, again receive message on the message queue to first half, and carry out before the SELECT at every turn, all the active link in the link pond to be formed a link set, be blocked on this link set by the SELECT function.
● the link in the link pond has only a worker thread to read and write, and has got rid of multithreading and has read while write the collision problem that causes.
● the quantity of worker thread and the quantity of message queue can on-the-fly modify according to user's configuration, to satisfy performance demands.
For the means of communication of the specific embodiment of the invention, as shown in Figure 4, its concrete handling process can comprise the following step:
1) after the master control thread starts, creates corresponding message queue, worker thread and link pond.This is the process of system initialization.The master control thread is set up the communication link of WAP application end and WAP server end or terminal room according to the message of terminal or WAP server end, finishes the interacting message of WAP application end and WAP server end or terminal room; And with message deposit to message queue.
2) worker thread receives message on the message queue by the unblock mode, if receive new message, exceed certain threshold value with receiving continuously for quantity empty or that receive up to message queue, after Message Processing, the message link corresponding is stored in the link pond of this worker thread management.In the present embodiment, the threshold value that receives message gets 200.
3) worker thread adopts multiplexing technique, and all links that belong in the link pond of this thread are added in the set, is blocked in the set with SELECT, if having data transmit-receive or time to surpass 100 milliseconds, will return immediately.
4) if there are data to need to receive, then carry out receiver function and will receive complete data sending to the WAP application end.If there are data to need to send, then carry out the transmission function and send the data to terminal.
5) if SELECT is overtime to be returned, then carry out the overtime detection of Link State, prevent that the long-time free time of link from causing connection to be hung.
Adopt after the communication system based on HTTP of the present invention, the performance of whole system and stability have all had significantly raising, find that through contrast test the treatment effeciency of system architecture of the present invention is about the twice of existing systems framework; And aspect stable, adopt the WAP gateway of existing system framework, after operation a period of time, the leakage of a large amount of connection resources can appear, cause the paralysis of WAP gateway, and adopt system architecture of the present invention, long-play does not all have to occur above problem, ruuning situation is normal fully, has improved the overall performance and the reliability of WAP gateway greatly.
