S3, event chained list not by lock, then goes to judge whether thread C is synchronizing, no matter whether thread C is intended to traversal in synchronization
Chained list processes event successively.
The implementation method of bi-directional synchronization between router the most according to claim 5, it is characterised in that described thread C holds
Row process is as follows:
S1, thread C initialize；
S2, it is judged that judge lock in time, i.e. judges whether the time of router R1 and router R2 synchronizes, if time synchronized, then
At interval of the synchronous directory of 5 seconds querying router R1, and whether the synchronous directory of router R1 changes in contrasting 5 seconds；If the time
Asynchronous, show thread block, until the time period is correct, then at interval of the synchronous directory of 5 seconds querying router R1, and contrast 5
In second, whether the synchronous directory of router R1 changes；
S3, if the synchronous directory change of router R1, then judge thread B whether at local synchronization, if thread B is in this locality not together
Step, then the file download updated by router R1 is to local；If thread B is at local synchronization, then wait that thread B synchronously completes.
9. according to the implementation method of bi-directional synchronization between the router of described in claim 5 or 6, it is characterised in that described thread A's
The structure of storage event is as follows:
Typedef struct actionEvent{
Char action[20]；// file activities event
Char*oldName；// ancient deed name
Char*newName；// new filename
Char*oldFolder；// old catalogue
Char*nerFolder；// new directory
}
Event change is listed as follows
{ " modify ": "<file is modified>",
" addfile ": "<newly-increased file>",
" move ": "<mobile file>",
" rename ": "<file is renamed>",
" delete ": "<file is deleted>",
" dragfile ": "<file is dragged>",
}。
10., based on the system of the implementation method of bi-directional synchronization between the router described in any one of claim 1-9, its feature exists
In, including router R1 and router R2, router R1 as active router, router R2 is as from router, router R1
All supporting to store with R2 to arrange, router R1 includes web server and the interface of configuration access port；Router R1 provides registration
Function, provides unique certification key after supporting registration, it is simple to the certification of access device；Router R1 provides webdav agreement
Support；Router R1 provides the interface of configuration synchronous directory, and router R2 provides the configuration interface of local synchronization catalogue, route
Device R2 provides the program of monitoring local file change；The action of router R2 offer process monitoring local file carries out the journey responded
Sequence；Router R2 provides the program whether synchronous directory of querying router R1 changes.
