Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.

In order to can preferably following example be understood, first to the technology relevant to following example Simply introduce.

The background of the present embodiment application may include that WOC passes through TCP agent equipment (proxy) and intercepts and captures network The data of upper transmission.As in figure 2 it is shown, on link, internodal TCP connects is resultant, the most adjacent It is all that independent TCP connects between individual node, is all independent TCP three-way handshake process.

Concrete, TCP three-way handshake process can be, but not limited to include:

In Client(client) with WOC1 set up is connected before, first, Client to WOC1 transmission SYN (Synchronize Sequence Numbers, synchronizing sequence is numbered)；Then, WOC1 is to Client Send SYN ACK(SYN response)；Finally, Client sends ACK to WOC1.

Wherein, TCP three-way handshake process is not construed as limiting by the present embodiment, is well known to those skilled in the art Technology, in this no limit.

TCP when LAN (can be between transmitting terminal and WOC1, between WOC2 and receiving terminal) When (Transmission Control Protocol, transmission control protocol) connects abnormal chain scission, do not consider The concordance of cache1 Yu cache2, directly close WAN(can be between WOC1 and WOC2) TCP Connect.

During as it is shown on figure 3, TCP connects abnormal chain scission, between cache1 and cache2, the data of storage do not have Synchronize, i.e. in cache1 with cache2, the data of storage are inconsistent, it is impossible to the data not stored Index is decoded, and during WAN retransmits, if TCP connects abnormal chain scission, is then establishing link After, in addition it is also necessary to carry out the transmission of data, so, add WAN data mutual, strong influence WAN The speed of transmission.

Concrete, in Fig. 3, with Sever(server) illustrate to Client transmission data instance: Sever sends data to be transmitted to WOC2；Data to be transmitted is carried out encoding (to include that calculating is treated by WOC2 The cryptographic Hash of transmission data)；Calculated cryptographic Hash is sent to WOC1, due to cache1 and cache2 Asynchronous, i.e. cache1 does not stores data to be sent, therefore cache1 cannot be to the cryptographic Hash received It is decoded (i.e. calculating data to be transmitted according to cryptographic Hash).It can thus be seen that the mistake retransmitted at WAN Cheng Zhong, if TCP connects abnormal chain scission, then add WAN data mutual, strong influence WAN transmission Speed.

Simple in order to describe, and connection presented below (such as, LAN(Local Area Network, local Net) connect and WAN connection etc.) can be all that TCP connects.

In order to solve the problems referred to above, the processing method of the present embodiment a kind of abnormal chain scission of offer, and the method Executive agent can be the first control equipment, as shown in Figure 4, may include that

In order to make after connecting recovery, the index of the first data block can be decoded by the second control equipment, Then when the LAN chain rupture that first controls equipment, first controls equipment controls equipment by wide area network to second Send the first data block, in order to the second control equipment stores the first data block.

402, after the first LAN controlling equipment place connects recovery normally, first controls equipment to second Control equipment sends the index of the first data, in order to second controls equipment obtains the according to the index of the first data One data.

Wherein, the first data are the data of the first data block.

After the first LAN controlling equipment connects recovery normally, in order to save Internet resources, then the first control Control equipment can send the index of the first data to the second control equipment, and (size of the index of the first data is less than The size of the first data), owing in the second control equipment, storage has the first data block, therefore, second controls to set For the index of the first data being decoded, and then obtain the first data.

After using such scheme, when the first LAN controlling equipment connects chain rupture, first controls equipment leads to Cross wide area network the first data block to be sent to the second control equipment storage, so so that in the second control equipment Storage has all data blocks in the first control equipment.After connecting recovery, first controls equipment to the second control When control equipment sends the index of the first data, owing to the second control equipment storage has the data that this index is corresponding, Therefore the second control equipment can obtain the first data after being decoded this index, it is to avoid first controls to set Transmit the first data between standby and the second control equipment, decrease wide area network data interaction, add wide The speed of territory net transmission.

The present embodiment provides the processing method of another kind of abnormal chain scission, and the executive agent of the method can be second Control equipment, as it is shown in figure 5, may include that

501, the first control that the second control equipment is sent by wide area network reception the first control equipment that stores sets First data block of standby storage.

Wherein, the first data block can be the first control equipment after the LAN chain rupture at self place to described Second controls what equipment sent.

After making connection recover, the index of the first data block can be decoded, then by the second control equipment Second control equipment can receive and store first stored in the first control equipment that the first control equipment sends Data block.

502, second control equipment reception the first control equipment connects extensive at the first LAN controlling equipment place The index of the first data sent after Fu.

Wherein, the data during the first data are the first data block.

503, the second control equipment obtains the first data according to the index of the first data.

After the first LAN controlling equipment connects recovery normally, in order to save Internet resources, then the first control Control equipment can send the index of the first data to the second control equipment, and (size of the index of the first data is less than The size of the first data), owing in the second control equipment, storage has the first data block, therefore, control equipment The index of the first data can be decoded, and then obtain the first data.
