Control method, apparatus, and system for collecting traffic statistics

A control node, comprising:

• a memory configured to store computer-readable instructions;
• and
• a processor configured to implement the computer-readable instructions to:
• receive, by the control node, a statistics collection instruction triggered by a user operation, wherein the control node is communicatively coupled to a plurality of forwarding nodes;
• generate, by the control node in response to the user operation, correspondence between Border Gateway Protocol (BGP) attribute information and action information, wherein the correspondence indicates that one of the forwarding nodes is to perform an action associated with the action information to packets identified by the BGP attribute information, and wherein the action associated with the action information comprises a traffic identifier for the packets identified by the BGP attribute information;
• and
• send, by the control node, a Border Gateway Protocol Flow Specification (BGP FlowSpec) packet comprising the correspondence to the forwarding nodes.

A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable medium that, when executed by a processor, cause a control node to:

• receive, a statistics collection instruction triggered by a user operation, wherein the control node is communicatively coupled to a plurality of forwarding nodes;
• generate, in response to the user operation, a correspondence between Border Gateway Protocol (BGP) attribute information and action information, wherein the correspondence indicates that one of the forwarding nodes is to perform an action associated with the action information to packets identified by the BGP attribute information, and wherein the action associated with the action information comprises setting a traffic identifier for the packets identified by the BGP attribute information;
• and
• send a Border Gateway Protocol Flow Specification (BGP FlowSpec) packet comprising the correspondence to the forwarding nodes.
