Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic diagram of incident distributing layer of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Like Fig. 1～shown in Figure 2; Communication system based on the incident distribution; Comprise service application layer, as the cross-platform encapsulated layer of incident distributing layer, operating system, commercialization or the operating system layer of increasing income at Distribution Events center; Described service application layer is accomplished message communicating through the incident distributing layer, the socket mechanism that is used for interprocess communication that described incident distributing layer adopts the cross-platform encapsulated layer of operating system to provide, and described communication system is opened up one and is shared region of memory in internal memory.
Present embodiment is designed a kind of realization technology of the interprocess communication based on incident distribution; The basis of promptly accomplishing interprocess communication is based on event number; Through adopting communication target the form of five-tuple to transmit communication; Five-tuple is to be accomplished by module No., event number, communication type, communication buffer, communication length, and because a plurality of process can be ordered same incident simultaneously, accomplishes broadcast communication like this.
Present embodiment has adopted the design philosophy of structure hierarchies, and whole communication system is divided into the structure like Fig. 1, the concrete composition: the commercialization or the operating system layer of increasing income, the cross-platform encapsulated layer of operating system, incident distributing layer, service application layer.
Service application layer: application program, accomplish corresponding business.
Incident distributing layer: accomplish interprocess communication based on the incident distribution.
The cross-platform encapsulated layer of operating system: the operate services interface that operating system is provided carries out cross-platform encapsulation.
The commercialization or the operating system layer of increasing income: operating system.
In the present embodiment, the incident distributing layer is accomplished the message communicating in the service application layer, supports synchronously and asynchronous communication mechanism; Support point-to-point, one-to-many, many-to-one traffic model; Support orders/message communicating of unsubscription, support the transmission of messages of endless size, simultaneously owing to exist the cross-platform encapsulated layer of operating system; The platform constraints of hardware and software under not receiving, this communication system can be operated in the environment of various platforms fully.The incident distributing layer is as the center of Distribution Events; The socket that inner realization mechanism has adopted the cross-platform encapsulated layer of operating system to provide and has been used for interprocess communication is machine-processed; So just improve stability property, reliability, the extensibility of incident message center, simplified the message communicating of service application layer.
The technical scheme of the incident distributing layer in the present embodiment is as shown in Figure 2:
Communication table: be arranged in the communication description table of shared drive, the information that comprises has:
Application services module number, event number, event type, communication buffer, communication length.When communicating, come the opposite end of obtaining communication, and accomplish the transmission of the particular content of communication through event number, communication type, communication buffer, communication length through module No..
Communication backbone center: the core of incident distributing layer.Major function:
Accomplish registration, issue unicast messages, issue broadcasting, message order message, the unsubscription message of application services module.
The realization principle at communication backbone center:
1. accomplish the registration of application services module:
When application services module general-purpose interface function call is registered, be logged into the module No. of application services module in the communication description table that is arranged in shared drive.
2. accomplish the issue unicast messages of application services module:
When application services module general-purpose interface function call issue unicast messages, application services module is passed to the communication objective ground at communication backbone center.The communication backbone center is the index search communication table through this communication objectively, comes the communication description symbol of obtaining communication destination, and initiates the connection of socket, sends message.
3. accomplish the issue broadcast of application services module:
When application services module general-purpose interface function call issue broadcast, application services module is passed to the communication event number at communication backbone center, and simultaneously be changed to the communication backbone center communication objectively.Broadcast that transfer receives is accomplished to the business module of ordering event number in the communication backbone center after receiving broadcast.The communication backbone center number be the index search communication table through communication event, obtains the communication description symbol of the application services module of ordering this event number, and initiates the connection of socket, transmission message.
4. the message of accomplishing application services module is ordered:
When application services module general-purpose interface function call order message, application services module is passed to the event number of ordering at communication backbone center.The communication backbone center is put through this incident number of ordering in communication table and is ordered sign, upgrades communication table.
5. accomplish the message unsubscription of application services module:
When application services module general-purpose interface function call unsubscription message, application services module is passed to the event number of ordering at communication backbone center.Sky is put through this incident number of ordering in communication table in the communication backbone center, upgrades communication table.
