Method, server, and system for data stream redirecting

A data stream redirecting method, applicable to a central node, comprising:

• receiving variance information of a first global database respectively uploaded by at least one service node, wherein the first global database includes multiple pieces of destination address information and application identities corresponding to the multiple pieces of destination address information;
• processing the variance information uploaded by each service node, to obtain total variance information;
• and
• based on the total variance information, updating the first global database to obtain a second global database.

A server, comprising:

• at least one processor;
• and
• a memory in communication connection with the at least one processor;
• wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor, such that the at least one processor executes a data stream redirecting method of:
• redirecting data streams based on a first global database, wherein the first global database includes at least one piece of destination address information and application identities corresponding to the at least one piece of destination address information;
• based on destination address information of data streams that traverse the service node within a first preset period and application identities corresponding to the destination address information, determining variance information of the first global database;
• uploading the variance information to a central node, and updating, by the central node, the first global database based on variance information uploaded by at least one service node, to generate a second global database;
• and
• acquiring the second global database from the central node and, based on the second global database, redirecting data streams.
