In specific embodiment as shown in Figure 1, message is distinguished to outlet through the entrance of business forwarding chip
Through port processing module, ACL matching module, classifier modules, L3 Service Processing Module and next
Jump package module, wherein:
Two packet loss reasons ID are set on the judgement node of port processing module:
Packet loss reason ID=1, represents that MTU is illegal；
Packet loss reason ID=2, represents that MAC Address judgement is illegal.
Three packet loss reasons ID are set on the judgement node of ACL matching module:
Packet loss reason ID=3, represents ACL-DropAny；
Packet loss reason ID=4, represents ACL strategy packet loss；
Packet loss reason ID=5, represents ACL CAR packet loss.
Three packet loss reasons ID are set on the judgement node of classifier modules:
Packet loss reason ID=6, represents that flow point class does not mates (sub-interface does not exists)；
Packet loss reason ID=7, represents stream classification policy packet loss；
Packet loss reason ID=8, represents flow point class CAR packet loss.
Four packet loss reasons ID are set on the judgement node of L3 Service Processing Module:
Packet loss reason ID=9, represents the illegal packet loss of IP TTL；
Packet loss reason ID=10, represents IP verification and verifies unsuccessfully；
Packet loss reason ID=11, represents that URPF detection is not passed through；
Packet loss reason ID=12, represents that routing table does not exists.
Two packet loss reasons ID are set on the judgement node of down hop package module:
Packet loss reason ID=13, represents that ARP searches unsuccessfully；
Packet loss reason ID=14, there is shown mouth queue congestion；
Additionally, reservation packet loss reason ID can also be arranged on business forwarding chip, it is used for extending, such as:
Packet loss reason ID=16, represents undefined reason packet loss.
Step 2, the plane that controls are that the message distribution of different attribute is unique " packet labeling ID " in advance,
For identifying specified services.Should " packet labeling ID " draw based on port, sub-interface or other features
Point, for example, it is possible to according to the classification of " L3 logic interfacing ", define " sub-interface to each sub-interface
ID " conduct " packet labeling ID ", it is somebody's turn to do " packet labeling ID " with configuration distributing to Forwarding plane.
Classifier modules in step 3, Forwarding plane receives and controls " the packet labeling ID " that plane issues,
And with the corresponding message of its labelling.
Step 4, when corresponding judgement node judgement message needs to abandon, then depart from main business flow,
Add in messages corresponding " packet loss reason ID " of this judgement node, and import place in packet loss processing module
