It should be noted that, client and client node in fact all are clients, client node is other clients outside the client of request content, with " client " and " client node " two notions the two role is distinguished herein.At this, refer to the client of request content with " client ", refer to other clients that resource can be provided to client with " client node ", promptly client both can be to the resource providing server request resource, also can be to the client node request resource.
Providing each self-configuring its other resources index file of equipment with resource below is that example describes.In the example of Fig. 1, resource providing server comprises management by synchronization server DTS_S_SM and content source server DTS_S_SP.Management by synchronization server DTS_S_SM is deployed on the valut of resource providing server, guarantee that the file renewal (comprising file increase, file deletion, up-to-date) on the valut can in time detect, and generate the index file of current monitored directory and then content of announcement source server DTS_S_SP.
Management by synchronization server DTS_S_SM comprises following function:
When A, startup, scanning needs the catalogue of monitoring, and index All Files information generates index file.
B, monitoring assigned catalogue (for example utilizing the mechanism of (SuSE) Linux OS) when the catalogue generation file of being monitored upgrades, produce the index upgrade signal.
C, after the index upgrade signal produces, then start scanning to respective directories, generate new index file.
D, according to the comparison of new and old index, judge that file upgrades (file increase, up-to-date, file deletion etc.), is recorded in the new index file.
When judging that according to new and old index file file upgrades, if up-to-date is arranged, when newly-increased file is perhaps arranged, need scanning once more that the catalogue of upgrading takes place, the file of renewal is arranged at those, if file size is consistent when scanning with the last time, decidable file does not for this reason upgrade, if file size changes, shows that file content upgrades, then need delay predetermined time to rescan, so that judge the file that upgrades whether finish by update all.
