Embodiment
The method of a kind of multichannel synchronous transmission provided by the invention is to realize the data transmission simultaneously between different channels between server end and the client through the IGRS agreement, thereby effectively improves the transmission speed of data.Utilize the IGRS agreement to realize that the implementation procedure of multichannel synchronous transmitting data is following:
See also shown in Figure 1 based on IGRS agreement multichannel synchronous transmitting data schematic diagram; Exploitation comprises mainly that based on the multi-channel data synchronous driving of IGRS agreement service setting up data server end 10 through IGRS protocol stack 30 is connected with data between the client 20, and the data delivery service of server end 10 comprises the detection of the idle data channel between idle channel detection module 12 charge server ends 10 and the client 20; File division module 14 is responsible for being divided into a plurality of data blocks to the bigger file of capacity by the requirement of setting; Transmission channel distribution module 16 is responsible for being dispensed to corresponding data transmission channel cutting apart good data block; Through data transmitting module 16 mode of a plurality of data blocks through the multichannel synchronous transmission is transferred to client 20 at last.The data reception module 22 of client 20 is responsible for receiving data block from different channels, reconfigures through file recombination module 24 again, forms a complete file.
For being had more, technical scheme of the present invention clearly demonstrates; More describe in detail in the face of technical scheme of the present invention down, the function that the data delivery service of server end comprises mainly contains: channel idle detecting, file division, transmission channel distribute, multichannel transmits data.
See also idle channel shown in Figure 2 and detect sketch map, the channel idle detecting function of server end is that the server detection is current has to be file transfer services for what channels.When finding two or more channel idle is arranged, the file transfer services of server end just can all be utilized the channel of free time, to accelerate the speed of file transfer.The idle channel scouting mainly is that QoS (the Quality of Service) parameter according to channel is confirmed.Server end starts the QoS of current all channels through carrying out system call to operating system, can satisfy the requirement that transmits file if find the QoS of current channel, and server end just starts this channel and carries out the data transmission.No matter be server end or client, different channels transmit with receive data in be to transmit and receive data through different threads.Therefore realization has the operating system support of supporting multithreading based on the Technology Need of the multichannel synchronous transmitting data of IGRS agreement.Certainly, also can use multithreading in the data transmission of same channel.
See also file division sketch map shown in Figure 3, the file division function of server end is for the file service that satisfy to transmit single big file size.Some video files for example, database file etc., their file size all reaches GB usually.The file division function mainly is to become the file division of these big file sizes several to be adapted at the different channels data block transmitted, like this, when detecting other channel idle, just transmits the data block of cutting apart through these idle channels.The division principle of file mainly is the parameter of the aspects such as priority level of the bandwidth of considering the balance main channel, the bandwidth of idle channel, the total capacity of file, the quantity of transmitting thread, file transmission, divides as required.The file fragmentation that on main channel, transmits size and be proportional to the bandwidth ratio of main channel and idle channel at the file fragmentation of idle channel transmission.If the main channel bandwidth is 2 times of the idle channel bandwidth, be 2 times in the file fragmentation size of idle channel transmission then in the file fragmentation size of main channel transmission.When the file total capacity is bigger; If the file delivery service of server end and client supports same channel multithreading to transmit, then the number of file fragmentation does not support that than the file delivery service of server end and client same channel multithreading transmission is many.So more can let multithreading start simultaneously, send the different files burst.When transmit preferential of file and than higher, and system's server end and client be when all supporting same channel multithreading transmission, and file fragmentation relatively can be more.Different bursts had different ID when file was carried out burst, so as can be correct when client is recombinated file couple together burst.The ID of burst is path, the filename at file place, the side-play amount of this burst relative file head.So just can be in a system burst of unique expression.When transmitting file fragmentation through different channels, the ID of file fragmentation at first transmits.Let client can know the information of this burst.If the number of files that transmits is many, total capacity is bigger but single file size just need not carry out burst to these files in the time of smaller, directly transmits single file through idle channel.
The transmission channel distribution module 16 of server end understands transmission channel separately that each data block size confirms, transmission Thread Count that transmission channel distributes, transmit race-entry such as priority; Send the thread of data well in corresponding channel allocation, with several to client.
See also Fig. 4 multichannel transmission schematic diagram data, the multichannel transmission data of server end are exactly to utilize the bandwidth of idle channel, carry out the transmission of data.After the channel idle detecting of server end was accomplished, just through the information of the present available channel of IGRS notice of settlement client, the notice client was at pending datas such as corresponding idle channels for server end.Server end and client are decided through consultation and are used the exchange message of idle channel all to carry out through the IGRS protocol stack.Found to have new idle channel when server end and can use utilization, it just in the process that the IGRS protocol service is called, tells client to have new channel to use with the form of service call notification.It is current to the passing a parameter of available channel that server end and client utilize the informing mechanism of IGRS agreement to consult, the transmission line number of passes that comprises the sign of available channel, starts at available channel, the file that transmits at available channel or file fragmentation information etc.And then setting up the transfer of data connection of available channel.Server end and client all by the notification message message switching data separately based on reply of IGRS agreement the inside, are decided through consultation passing a parameter of both sides.And the IGRS agreement is being played the part of the role of information Control information exchange bridge in the service of multichannel transmission data.
The data delivery service of client comprises: data channel assignment, multichannel receive data, file reorganization, file integrality inspection.
Race-entries such as the transmission channel that transmission channel distribution module 26 meetings of client are confirmed according to the data transmission channel distribution module 16 of server end, the transmission Thread Count that transmission channel distributes, transmission priority; Receive the thread of data well in corresponding channel allocation, the waiting for server end is come transfer of data.
See also multichannel data shown in Figure 5 and receive sketch map, it is the data that reception server sends from different channels that the multichannel of client receives data function.The idle channel that client receives server end transmits and just to start new thread after the notice and send data at the channel waiting for server end of correspondence.The data that send promptly comprise the file content of original, also comprise this channel files fragment information of fragments.
See also file reorganization sketch map shown in Figure 6, the file recombination module 24 of client is to be reduced to original to the data block reorganization that receives from multichannel.The foundation of recombination data piece is exactly a file fragmentation information.File fragmentation information is the information that when server end is through different channel transmission datas, at first sends.It comprises the ID of file fragmentation, the burst number of presents, the total capacity of file, the essential informations such as transmission number of times of this burst.All bursts that the file of client is binned in file carry out after transmitting and finishing.It can be connected to complete original to all bursts again according to the information of file fragmentation.
The file integrality inspection of client is the integrality that the file fragmentation that transmits is connected back check and correction file.When occurring some in the transmission course wrong the time; File connects possibility can be successful; But the file after connecting has difference with source file, and the file integrality inspection just abandons the file fragmentation that goes wrong, and transfers out the file fragmentation of problem again to the server end request.After receiving correct new file fragmentation, call the file recombination function once more and couple together file and original.
Describe the process of multichannel synchronous transmitting data below in detail.
At first be to carry out the IGRS protocol data to transmit service call, when client had the data delivery service that needs the invoking server end, client was just sent the data delivery service request of invoking server end to the IGRS agreement.Client at first was the service describing message that gets access to the data delivery service of server end before sending service invocation request.This service describing message has not singly been described the essential information of the data delivery service of server end; And indicated the function whether this service supports the multichannel shared bandwidth; Comprised the concrete parameter of supporting this function, like the channel of supporting (Ethernet, UWB, Blue tooth......), the maximum thread of whether supporting the transmission of single channel multithreading, support transmission etc.Client is initiated the file delivery service of invoking server end to server end according to the situation of service describing content of message and this equipment.If client is also supported the multichannel shared bandwidth; Then in service invocation request, specify this service call to use the support of multichannel shared bandwidth; Indicate the channel that this client is supported, this channel need corresponding to the service describing message of server end data transport service indicate support channel, whether support the parameters such as maximum thread that the single channel multithreading transmits, supports.
Server end is received the service invocation request of client later requirement and the current situation of this equipment according to client, for client provides file transfer services.Carry out data delivery service when calling through the IGRS agreement, server end and client just can use the channel of IGRS communication to carry out transfer of data after coordinating the parameter of service call.This channel is that server end follows client to utilize the channel of IGRS protocol interaction information, so this channel is available certainly channel.Need not carry out burst when transmitting file at the beginning, transmit because be to use this channel to carry out single channel under the situation of acquiescence to big file.
Then, server end carries out the idle channel testing, if client indicates the support of using the multichannel shared bandwidth in service call, then just begin to scout can communication with client for server end, and is available channel.This work requires irregular the development according to the transmission of service call; When detecting all channels that connect with client all available the time; And the parameter that the client service transmission of calling requires to know needs to transmit fast data, and server end is carried out data transport service with regard to launching all with available channels that client connects so.Server end was not just being carried out the idle channel testing before this service finishes like this.When all available channels can both be used for carrying out data delivery service, server end guarantee can not the absorb channel bandwidth, supply more urgent data interaction with reserved bandwidth.After transmitting, data find have some channel to use when carrying out; Then server end does not use earlier this channel; In data transfer procedure, again channel is carried out idle-detection; If server end detects in the channel that connects with client idle channel is arranged, then server end just can use this channel to carry out data to have transmitted.What when utilizing new detected idle channel to transmit, at first transmit is the burst information of file.Client need be used the file transfer record of up-to-date file fragmentation information updating client.Because this file fragmentation information changes at any time.File does not have burst when using the single-threaded transmission of single channel at the beginning.When finding to have new channel to use, server just carries out burst to file on the basis of original file, sends out new burst through newfound available channel.At this moment the file fragmentation information of client is outmoded; Server end is issued client to up-to-date file fragmentation information; The file fragmentation that sends with the new channel of notice client is what part of file, and what it is with respect to the skew of file header, and what the overall burst information of whole file is.
Next be the file fragmentation of data transfer procedure,, so just need do not carry out file fragmentation work if the file that data delivery service need transmit all is the set of the smaller file of single file size.The file that need transmit when data delivery service need carry out burst to file when having the bigger file of single file size to exist.File fragmentation in the data transfer procedure is a process of irregularly calling.If (comprise transmission of single channel multithreading and the transmission of multichannel multithreading) when server end uses the multithreading transmission, need carry out burst to file; If server end is investigated current when having new idle channel to use use, need carry out burst to file.Burst quantity is the conveyer line number of passes that starts simultaneously with the qos value of the Request Priority of main channel bandwidth, number of available channels, available channel bandwidth, service call, current channel, this service call function as input parameter.The bandwidth of general channel is big more, and the burst size that transmits at this channel is just big more; The priority of service invocation request is high more, and burst is just many more; The qos value of current channel is excellent more, and burst is many more; The conveyer line number of passes that this service call starts is many more, and burst is many more.
Server end carried out burst to file in the process of data delivery service if call, and client just need be recombinated to file when receiving data so.The foundation of file reorganization is the file fragmentation information that server end sends, and it has indicated the information of different file fragmentations and the overall burst information of file.The reduction source file couples together the burst of file according to the skew of burst at source file according to these information.
Therefore, multichannel synchronous transmitting data method provided by the invention can improve the speed of transfer of data fast on the basis that does not increase the conventional network equipment communication resource.
