(5) mail preservation module 105 links to each other with mail document parsing module 103, be used for: when mail transmission/reception module 102 receives mail and resolves through mail document parsing module 103, after the IDC sign distributes judge module 101 to judge, this mail is deposited in the mail queue of local ident C (i.e. an IDC100) again.Among the present invention, the IDC of mail sign is consistent or inconsistent with user's current I DC sign, all mail will be saved in the local mail formation, if inconsistent, then also will transmit when preserving.

The structure of the 2nd IDC200 is consistent with an IDC100, comprise IDC sign distribution judge module 201, mail transmission/reception module 202, mail document parsing module 203, interim mail document generation module 204 and mail preservation module 205, the structure of each module and function respectively with an IDC100 in above-mentioned module consistent, do not repeat them here.

Fig. 3 shows among the present invention the Email forwarding method flow process based on distributed I DC.

Carry out institute in steps before, distributed I DC of the present invention system lands situation according to user's history and will concentrate on user data among the single IDC originally and be assigned among each IDC in this distributed I DC structure, and distributes an ownership place IDC sign for each user.For example, if certain user lands on the IDC of Shenzhen for a long time, then with its data allocations to Shenzhen IDC, and for this user distributes Shenzhen IDC sign, the ownership place IDC that this sign is this user identifies.The alleged user data of the present invention is meant the information of this user's e-mail messages and user account number, and each mail all is made up of the IDC sign of mail essential information and mail.

The flow process that the present invention transmits mail may further comprise the steps:

In step S301, when the user landed an IDC100, an IDC100 utilized the IDC sign to distribute judge module 101 to distribute one the one IDC sign for it, and IDC sign becomes user's current I DC sign.

In step S302, an IDC100 utilizes mail transmission/reception module 102 to receive this user's new mail, and detailed process comprises: (1) initialization thread pond, read configuration file; (2) start scanning (Scanner) thread scan mail entry queue (incoming queue), finding has new mail in this mail entry queue; (3) new mail that is scanned is sent in the mail document parsing module 103.

In step S303,103 pairs of these mails of mail document parsing module are resolved, and distribute the IDC of 101 pairs of these mails of judge module to identify by the IDC sign and judge, specifically comprise: (1) mail document parsing module 103 resolves to this new mail the IDC sign of mail essential information and mail, this mail essential information comprises information such as addressee, sender, message body, annex number, attachment content as previously mentioned, and the IDC sign of mail is consistent with user ascription area IDC sign; (2) IDC sign distribution judge module 101 judges whether the IDC sign of the new mail that the user receives is consistent with this user's current I DC sign (i.e. IDC sign): if both unanimities are then changeed step S304 this email storage is arrived local (i.e. an IDC100); If inconsistent, then change step S305 this mail is forwarded to its ownership place.

In step S304, consistent if the IDC sign distributes judge module 101 to judge that the IDC that learns this mail identifies with IDC sign, then utilize mail to preserve module 105 this mail is deposited in the mail queue of this locality (i.e. an IDC100).

In step S305, if 101 judgements of IDC sign distribution judge module learn that the IDC sign of this mail is inconsistent with IDC sign, its ownership place is the 2nd IDC200, then this mail is kept at this locality and also forwards it to simultaneously among the 2nd IDC200.The detailed process of transmitting comprises: (1) utilizes interim mail document generation module 104 to generate interim mail document according to the mail essential information that parses, and deposits the filename of this interim mail document in forwarding queue; (2) from forwarding queue, read the filename of being stored by the forwarding thread in the thread pool, whenever read one and then it is deleted from former formation; (3) in mail entry queue, read corresponding interim mail document content according to the filename that reads, and deposit in the pre-assigned local cache; (4) the interim mail document in the local cache is packaged into packet, and this packet is sent to the 2nd IDC200 by mail transmission/reception module 102.

In step S306, the 2nd IDC200 receives this interim mail document, and this mail deposits in the mail queue of this locality (i.e. the 2nd IDC200) the most at last.Detailed process comprises: (1) the 2nd IDC200 receives packet by mail transmission/reception module 202, and it is kept in the local temp directory, this step also can further be returned when carrying out and receive successful filename to an IDC100, then transmits thread and can delete corresponding interim mail document in mail entry queue according to filename; (2) resolve by the interim mail document in 203 pairs of local temp directorys of mail document parsing module, thereby recover the mail essential information, comprise information such as addressee, sender, message body, annex number, attachment content; (3) generate mail document according to the mail essential information that parses, and this mail is deposited in the mail queue of the 2nd IDC200.

Like this, final result is, this ownership place is that the mail of the 2nd IDC200 respectively has portion in an IDC100 and the 2nd IDC200, when landing two IDC next time, the user all can directly visit this mail nearby, needn't go queuing to read to ownership place, shorten the time of mail access request, greatly improved the efficient of visit.

In addition, if user's repeated multiple times is landed an IDC100, then the data that this user can be kept on the 2nd IDC200 migrate among the IDC100, land an IDC100 later on again and just can visit its whole historical mails nearby.Specific implementation is: the number of times that the user lands an IDC100 is set to a threshold value N, and (N is a positive integer, N 〉=1), the number of times that lands an IDC100 as the user is during less than this threshold value N, then in this user's ownership place IDC, obtain data (i.e. this user's e-mail messages and account information thereof), if the user lands the number of times of an IDC100 when surpassing this threshold value N, distributed I DC of the present invention system then moves to the user among the one IDC100 in the data of ownership place, after this then can directly visit its historical mail nearby in an IDC100 when the user lands an IDC100 again.

Should be noted that, be new mail to be had at ground be forwarded among its ownership place IDC (i.e. the 2nd IDC200) in the said method flow process, but mail of the present invention is transmitted and is not limited to transmit targetedly, if comprise more a plurality of IDC in this distributed mailing system, as shown in fig. 1, the current I DC that then judges the IDC sign learn the mail of being received and user in above-mentioned steps S303 identifies when inconsistent, and step S304 can preserve this mail and forward it among other all IDC in this distributed IDC system.For example, if comprise Beijing IDC, Shanghai IDC, Wuhan IDC, Guangzhou IDC, Xi'an IDC, Tibet IDC in the distributed I DC system, and user's ownership place IDC is Beijing IDC, then when the user lands in the IDC of Shanghai and receives new mail, this mail delivery can be forwarded among Beijing IDC, Wuhan IDC, Guangzhou IDC, Xi'an IDC, the Tibet IDC time the IDC of Shanghai.Final result is, this ownership place is that the mail of Beijing IDC respectively has portion in all IDC, all can directly visit this mail nearby when the user lands arbitrary IDC next time, needn't go queuing to read to ownership place, shorten the time of mail access request, greatly improved the efficient of access mail.

In one of them embodiment of the present invention, when the judged result of step S303 is unanimity as shown in Figure 3, also can execution in step S305 and S306 after the execution in step S304, can't cause conflict.Also promptly, when the user lands its ownership place IDC and receives new mail, also this new mail can be forwarded among other all IDC in the distributed I DC system and back up, when the user lands wherein arbitrary IDC next time, all can directly visit this mail nearby.

The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
