The invention discloses a
data processing method, apparatus and
system, which comprises: when control strategy of control
management plane is updated, updating the edition information of the control strategy; when data plane receives data message while the no item including the current
data stream identification exists in the
stream table of data plane, establishing an item in the
stream table of data plane and
processing the current data message according to the established
stream table item or the control strategy of the control
management plane; when the item including the current
data stream identification exists in the stream table of data plane, judging whether stream table item edition information matches the edition information of the control strategy of the current control
management plane, if matching,
processing the current data message according to the stream table item, otherwise,
processing the current data message according to the control strategy of the current control management plane. The invention can insure the consistency of the
data processing mode of data plane and the control strategy of the control management plane, consequently, avoid
data processing errors.
