Embodiment
For making above-mentioned feature and advantage of the present invention become apparent, special embodiment below, and coordinate institute's accompanying drawing to be described in detail below.
The present invention is directed to legacy network data synchronous in defect, a kind of high reusable network data synchronizing method is proposed.
As shown in Figure 1, the mutual burst types of Network Synchronization module and other system has several as follows:
1 receives synchrodata from multiple upper application module of the machine;
2 in subnet other main frames receive synchrodata, wherein, subnet inter-sync data use UDP socket transmission;
3 receive synchrodata from subnet outdoor main unit, and wherein, between subnet, synchrodata uses TCP socket transmission;
Accordingly, Network Synchronization module is to there being following functions point:
1 by this locality produce synchrodata mail to other main frames
2 receive from network UDP socket the synchrodata that in subnet, other main frames send.
3 receive the synchrodata of subnet outdoor main unit transmission from network TCP socket.
As shown in Figure 2, based on reactor pattern, all mutual trigger data (local data, UDP socket data, TCP socket data etc.) with Network Synchronization module managed as event, Network Synchronization module comprises event DeMux module, event processing module.Event DeMux module in charge reads event, Distribution Events, and event processing module then completes the process to event.
Event DeMux module independent operating is in main thread, and event processing module runs on the thread pool (N can join, and adjusts according to bearer traffic) be made up of 1 ~ N number of worker thread.Main thread is responsible for reading event, and to thread pool Distribution Events, thread pool then processes the event be distributed to, and both form a complete Network Synchronization module.
Based on the basic model of above-mentioned reactor pattern, the step of newly-increased a kind of synchronization data types is then decomposed into:
1, for event DeMux module, registers the distribution policy of this synchronization data types.Distribution policy acquiescence uses Round-Robin pattern, if synchronization data types can not be registered without specific demand.Event DeMux module provides the login mechanism of distribution policy, can facilitate the flexibly customizing of various synchronization data types.
2 for event processing module, registers the process function of this synchrodata, comprises this synchrodata processing locality logic, forward process logics etc.Wherein, processing locality logical AND institute synchronization data types is correlated with, and different synchronization data types processing logic is different, and with radius data instance, processing locality logic comprises and data are added local hash shows, writes local file etc.Similarly, forward process logic is also relevant to institute synchronization data types, such as whether this synchrodata is transmitted to other main frames, this synchrodata is transmitted to subnet interior nodes or subnet exterior node etc.
The Network Synchronization module gone out based on this model construction is as shown in Figure 3:
The bottom is network communication module, and major function comprises: according to the configuration of network application Module registers, creates thread pool, safeguards socket state, monitor socket read-write event and give network application resume module by the data of reading.Network Synchronization module realizes based on libevent storehouse the monitoring of socket, state-maintenance.
Illustrate, the configuration of upper application module registration is as follows:
The Thread Count of thread pool
TCP listening port
UDP listening port
Ringbuffer
So, the realization of network communication module is as follows:
For the Thread Count of thread pool, network communication module starts corresponding Thread Count according to this configuration, forms the thread pool that this synchrodata is corresponding.
For TCP listening port, the corresponding interface that calling libevent storehouse provides reads event and event handling call back function, to monitor, to process coming connection to the registration of TCP listening port.Event handling call back function realizes: accept socket and connect, and according to distribution policy, this socket is connected certain thread be assigned in thread pool.
For UDP listening port, create socket, and according to distribution policy, this socket is connected certain thread be assigned in thread pool.
After this, in thread pool, each worker thread connects the socket received, and the corresponding interface registration socket that calling libevent storehouse provides reads event and reads time out event and event call-back function.Wherein, read event call-back function: connect from socket and read data, call the callback interface of network application Module registers, the data received are processed.Read the process of time out event readjustment: be used for monitoring socket connection status, show that socket may disconnect, carry out socket and connect process such as detecting, reconnect.
Network application module, is registered to network communication module during initialization, uses the network channel that network communication module is safeguarded in running, controls sending strategy, provides Network Synchronization transmission interface to upper application module.
Upper application module, for the data needing Network Synchronization, is registered to network application module during initialization, need directly to call during Network Synchronization the Network Synchronization transmission interface that network application module provides in running.
Like this, just achieve layered shaping, upper strata does not need to be concerned about the data exchange process compared with bottom, is absorbed in application data process completely.
From the transmission and reception flow process of data, resolution process step is as follows:
Transmitting terminal:
1. according to the configuration such as network topology, send mode (tcp, udp) of configuration, carry out initialization, create socket etc.
2. upper application module is called transmission interface and is sent, and transmission interface automatically provides and sends according to socket state and priority, and application layer does not need to pay close attention to details.
Receiving terminal:
1. create monitoring event based on socket event
2. read event, call back function corresponding to event of calling processes.
3. the process function of application layer registration processes
Use method provided by the invention, can add fast and need synchronous data type and processing logic thereof, without the need to paying close attention to bottom layer realization details.
Embodiment:
To increase GTP signaling data synchronously,
A subnet comprises 20 main frames, the equal access user Internet data of every platform main frame and GTP signaling data.Every platform main frame needs the GTP signaling data of parsing to be synchronized to other main frames in subnet, is associated with user terminal to realize user's Internet data.
Be equivalent to application module Network Based and increase a kind of synchrodata:
Need to make following amendment, as shown in Fig. 4-initialization section:
GTP application module needs to network application Module registers data processing call back function.Interface is as follows:
NetsyncRegAppFunc(int app_type,app_proc_func_tprocess_func)；
It is more than required amendment part.
Operational process is as shown in part when Fig. 4 runs:
The 1 GTP synchrodata that other main frames are sent, network communication module thread pool worker thread listens to the event of reading, receive data and call the call back function that network application module registers to it, resolution data packet header in mixed-media network modules mixed-media call back function, judge it is GTP types of synchronization data according to the application type carried in data packet head, then call the readjustment process function that GTP module is registered to it, finally complete the process to GTP synchrodata.
2 for the GTP data of local parsing, if need synchronous, then the interface that calling mixed-media network modules mixed-media provides carries out transmissions synchronously.The main practical function of this transmission interface: the data to be sent imported into by GTP application module and data type thereof are assembled into packet, put into ringbuffer, by reading ringbuffer event, (this event needs initial phase to be registered by network communication module to network communication module, and registered events process function), from ringbuffer, read data, and call corresponding process function and process.
