However, the defect of the existing method is that the search of the flow classification table depends on the flow classification hardware identification, but the number of the flow classification hardware identification of the network equipment is limited. For a network with a large number of users, the limited resources of the flow classification hardware identification limit the manageable The number of stream classifications
In a large-scale network, traffic classification management can only be performed on a limited number of users

The invention provides a stream classification processing method and device, and the method comprises the steps: enabling a user network address to be mapped to a globally unique stream classificationsoftware identifier in each VPN virtual private network; mapping one of a plurality of stream classification hardware identifiers to one of the software classification identifiers of the different VPNs; establishing a routing table entry corresponding to each stream classification software identifier in each VPN routing table, wherein the routing table entry corresponding to each stream classification software identifier records a network address mapped by each stream classification software identifier and a stream classification hardware identifier; and executing stream classification processing based on each stream classification hardware identifier in different VPNs. According to the invention, through the stream classification software identifiers mapped by the stream classification hardware identifiers, the user manageable stream classification number is increased.
Description
Technical field [0001] This application relates to the technical field, and specifically to a flow classification processing method and device. Background technique [0002] In the existing flow classification processing method, the classification is performed based on the user's network address, the flow classification hardware identifier is assigned to the network address, the routing table entry of each user network address is established according to each flow classification hardware identifier, and the flow of the network address is classified The hardware identification is stored in the routing table entry. [0003] When a network device forwards a data message, it finds a matching routing table entry according to the network address of the data message, obtains the flow classification hardware identifier recorded by the routing table entry, and then searches the flow classification table according to the flow classification hardware identifier to obtain the corresponding flo...
