Description
Technical field
The present invention relates to field of data transmission, particularly relate to data sending, receiving method and device, data transmission method and
System.
Background technology
In a lot of network processing environment, owing to there is the input network interface bandwidth place more than single back-end analysis equipment
Reason ability, it is therefore desirable to according to the disposal ability of back-end analysis equipment, input flow rate is assigned to multiple analytical equipment and process.
The data collected are passed to analytical equipment by shunting device, and main collection is all tcp data stream.For the TCP number collected
According to stream, being all based on a complete interaction sequence and be analyzed the when of analysis, a complete interaction sequence contains multiple
TCP message.Therefore, being analyzed when, it is necessary to assure multiple TCP message of complete sequence enter same analysis and set
Standby, otherwise can cause and analyze unsuccessfully.
Traditional way is data directly to be sent from network interface card with the form of Ethernet message, and analytical equipment connects oneself
Receiving Ethernet message, package analysis.But so receive message and can cause analytical equipment degraded performance, it is easy to report lost literary composition.
Prior art improves for disadvantages mentioned above, shunting device increases TCP Client module, sets in analysis
Standby middle increase TCP service module, by setting up TCP channel between shunting device and analytical equipment, transmission front-end collection arrives
Bypass tcp data.Although this improved method ensure that data message will not be lost, but TCP Client module is nearly all
The form using software realizes, i.e. the branching process of the network equipment is to realize in the driver of equipment mostly.This reality
Existing mode can increase the load of the network equipment, affects the disposal ability of other business, and speed is the most limited, and performance is the most limited.
Have at present the network equipment begin to use hardware realize part TCP function, i.e. high speed shunting device TCP Client be
In hardware, (or main body is based on hardware) realizes, it is ensured that equipment can shunt in the case of total interface flow is fully loaded in real time,
Accelerate transmission speed.
But, hardware TCP Client has two shortcomings, and one is the response message that TCP can not process the analytical equipment of complexity,
Two is that TCP cannot oneself go to understand which message can make up a complete analytical sequence, and it can only be some continuous print
(TCP) information stream gives same analytical equipment.Therefore, if the analytical equipment being currently running is died or software crash,
Shunting device is when migrating, and when i.e. connecting another analytical equipment, does not knows to start to transmit data from where, it is more likely that make
Becoming analysing content, a most complete analytical sequence part passes to the equipment of collapse, and another part is passed to new analytical equipment, caused
Analyze unsuccessfully.Meanwhile, if software processes is very slow, the data of shunting device accumulation will be cumulative, will also result in data and loses
Lose.

Flow device 110 and analytical equipment 220 set up TCP channel, send TCP message sequence.By in the sequence of message complete to
Multiple messages carry out compiling sequence number, then by the marking serial numbers of analytical equipment 220 feedback, the TCP Client of shunting device 110
The sequence number of the message of the sequence of message sent is needed when can determine that reconnect.Send message by this marking serial numbers, protect
Demonstrate,prove the integrity that sequence of message sends, prevented loss of data, improve the work efficiency of analytical equipment 220.
Preferably, said method further comprises the steps of: S10: according to preset rules, the message in sequence of message is compiled even
Continuous sequence number.Concrete, Fig. 2 is that in a kind of data transmission method for uplink of the present invention, the sequence number of message compiles schematic diagram, as in figure 2 it is shown,
Message different in size, each message has a numbering, starts message is compiled sequence number from message 1, can rollback.The sequence of message
Number it is continuous print, as it can be seen, from sequence number 3 to sequence number 12.If 16, after having arrived 0xffff, next test serial number
It is 0.
Above-described embodiment is improved, obtains preferred embodiment.Fig. 3 is the complete of a kind of data transmission method for uplink of the present invention
The rapid schematic diagram of synchronizing.As a specific embodiment of the present invention, as it is shown on figure 3, a kind of data transmission method for uplink, including step:
S10: the message in sequence of message is compiled continuous print sequence number according to preset rules；S11: send the message with sequence number to analyzing
Equipment 220；S12: monitor the marking serial numbers whether receiving analytical equipment 220 feedback；S13: when receiving analytical equipment 220 times
During the described marking serial numbers presented, record described marking serial numbers；S14: judge whether shunting device 110 reconnects to new analysis
Equipment 220；If so, next step is performed, otherwise repeated execution of steps S11；S151: the last time is recorded according to preset rules
Described marking serial numbers is as the beginning sequence number of next message to be sent；S16: send described message according to described beginning sequence number
To new analytical equipment 220.
Concrete, the present invention marking serial numbers by analytical equipment 220 feedback, can determine whether that a complete sequence of message is
No transmission completely is terminated, simultaneously when shunting device 110 reconnects new analytical equipment 220, it is possible to determine next step needs
The test serial number sent, it is to avoid occur that the message in a sequence of message sends to different analytical equipments 220, cause message not
Completely, it is impossible to carry out the analysis of sequence of message.
Preferably, S131 is further comprised the steps of: after described step S13 " shunting device 110 records described marking serial numbers ": release
Put sequence number and come the space that the described message before described marking serial numbers is corresponding.Concrete, the present invention is learnt by marking serial numbers
Complete message sequence, the space corresponding to complete sequence of message that timely removing has sent and received, it is possible to reduce slow
The memory space that the data deposited take, improves the processing speed of shunting device 110.
