Claim of US Patent No. 9,191,439

1. A method for data synchronization in a content delivery network (CDN), comprising:
a data synchronization processing manager, a plurality of data synchronization agents and a plurality of data synchronization
processing clients, wherein one or more of the plurality of data synchronization clients functionally belong to one of the
plurality of the data synchronization processing agents; wherein the data synchronization processing manager does not connect
with any of the plurality of synchronization clients, and the synchronization processing agent does not reside on any of the
plurality of synchronization clients; wherein

a data synchronization client of the plurality of data synchronization clients requesting the data synchronization processing
manager for obtaining a data synchronization processing agent of the plurality of data synchronization agents to which the
data synchronization client functionally belongs and establishing a heartbeat connection with the data synchronization processing
agent to acquire operation status of the data synchronization processing agent; and

the data synchronization processing manager scanning a management side database, and when a synchronization task needing to
be informed to the data synchronization client is scanned in the management side database, the data synchronization processing
manager generating the synchronization task for corresponding synchronization processing agent in an ability side database.
