Using the typical hardware resource mode of network processing unit, a kind of aggregation group member port switching rate that promoted is provided
Method, process communication leads to port switching time longer problem between improving traditional CPU.The embodiment of the present invention is using distributed
With interior transmission communication mode, mechanism is reported using the interruption of this plate CPU, this plate CPU sends control message, control to network processing unit
Comprising aggregation group member port information to be deleted or to be added in message processed, network processing unit is real according to control message port information
Existing aggregation group member port adds or deletes.Fig. 3 is the flow chart that CPU according to an embodiment of the present invention issues control message
One, as shown in Figure 3, the specific steps are as follows:
Step S302, when CPU detects that aggregation group member port state becomes down from up or becomes up from down,
CPU sends control message to network processing unit NP, and header carries aggregation group member port information to be added or to be deleted；
Step S304, control message enter the microcode module of network processing unit；
Step S306, corresponding micro code program look into hardware list according to port information etc., and hit of tabling look-up adds in hardware list
Add or delete corresponding aggregation group member port, the microcode of miss does not operate；
Step S308, while network processing unit protocol layer receives after controlling message, is configured, is added according to heading information
Add or delete corresponding software register list item.
For aggregation group when receiving network flow, deleted port no longer receives stream, realizes the fast convergence of aggregation group；Just
The port of addition will receive stream, realize that the quick load of aggregation group is shared.The triggering factors that aggregation group port is switched fast have two
It is a: interruption and port polling.But the Plug Action for only responding optical fiber is interrupted, so the worst performance being switched fast depends on end
The period of mouth poll and thread priority.
Fig. 4 is the flowchart 2 that CPU according to an embodiment of the present invention issues control message, as shown in figure 4, specific steps are such as
Under:
Control message is divided into unicast control message and Broadcasting Control message.When the port information that header carries is Home Network
When network processor port, this plate CPU sends unicast and inserts packet voice for microcode processing；When the port information that header carries is non-
When present networks processor port, this plate CPU, which sends to broadcast, inserts packet voice, and microcode goes out this message broadcasting, the net of corresponding ports
Network processor microcode is handled, and processing information is returned.
Polling mode is regardless of port information is either with or without update, and the transmission request of CPU all timings is inquired, it is possible to be looked into
More new information is ask, but most times are to return to empty information.Regardless of query result, CPU will be when next
Between point continue next round inquiry.As can be seen that the port polling CPU response time is long, low efficiency, poll port thread is excellent
First grade is turned up to greatest extent, polling cycle set as far as possible it is short after, performance of handoffs is likely to reach ms rank.
Step S402, CPU interruption starts, and sends control message；
Step S404 judges whether aggregation group port switching executes step in the case where the judgment result is yes to type of message
Rapid S406, it is no to then follow the steps S408；
Step S406, judges whether microcode looks into middle hardware list port information, executes step S410, no to then follow the steps
S412；
Step S408, other microcode process flows；
Step S410, microcode add/delete aggregation group port；
Step S412, microcode dropping packets.
Interrupt mode is interrupted using this plate CPU inserts packet, and microcode is directly handled, and it is as follows to omit intermediate steps: network processing unit
Protocol layer, which issues, is configured to bottom, and bottom receives configuration information and enters microcode processing.Such mode can will control switching time
Within ms.
Traditional port switching is given port status change notification using communication mechanism between plate using centralized distribution scheme
Master control borad, master control borad hand over processing message to be handed down to line card, and line card CPU is performed corresponding processing further according to type of message, efficiency ratio
It is relatively low；And interrupt mode carries out port switching and does not need by master control borad issuing message, using with interior transmission mode, directly by line
Card CPU is interrupted to give out a contract for a project and be handled according to port status variation, is greatly improved port switching efficiency.
Stabilization (preventing from shaking) operation is also added into it is important that interrupting and realization port being reported to be switched fast.Institute
Call link shake, it will be appreciated that cause port status to continue to become in up- > down, down- > up to repeat fast insert-pull fiber port
During change.It is switched fast because link shake in port can trigger, the polymerization of network processing unit add-back or deletion is formed
Mistake is deleted or is added again for member port, and network processing unit is not responding to shake, and will not delete or add again the member port,
There is also lead to member port configuration information mistake for the port that the port that should be added in this way is deleted, and should delete.
The anti-fluttering method that port is switched fast is when generation for the first time is shaken in port, and network processing unit will just correspond to
Aggregation group member port add or delete, and the time is recorded, if CPU detects port status again at the appointed time
This variation is then ignored in variation, then triggers interrupt operation again if more than the stipulated time, is can effectively avoid in the short time of port in this way
Repeat configuration error.
In addition, the method superiority that this plate CPU implement of interruption function port is switched fast is also embodied in: CPU is only needed to network
Processor sends specific control message, and network processor microcode carries out hardware table item resource read-write behaviour according to control message type
Make, is done directly port and cuts fastly.Compared with tradition switching, communication between plates step is omitted.
The response time of the embodiment of the present invention is made of two parts: CPU to microcode handles the time, and network processing unit read-write is soft
The part table time.The former is hardware pipeline, and microcode module is very efficient to the processing of message.Microcode is needed not move through directly to be read
It writes, so speed is also quickly.Therefore the response time of the method for the present invention is than the response time that process is cut in general port fastly smaller
It is more.
From the foregoing, it will be observed that the method for the present invention uses distribution with interior transmission mode, aggregation group port switching can be effectively reduced
Average response time, and do not need special hardware search hardware, provided by hardware common to general networking processor
Source can be realized.

The network topological diagram of connection, as shown in figure 5, uplink and downlink flow direction is opposite.
Aggregation group function only realizes that pon card is without this function on first line of a couplet card.First line of a couplet card CPU detects member port state
It changes to generate to interrupt and report, call Port interrupts processing function to carry out unicast or broadcast and insert packet.Fig. 6 is according to the present invention
The schematic diagram of the control message format of embodiment, as shown in fig. 6, packet format is divided into two parts: control type of message and port letter
Breath.Control type of message is appointed as polymerization group membership and updates, and port information includes effective marker position valid, aggregation group ID, port
Value portId, port operation: addition/deletion, MAC Address mac_addr, vlan value vlanId etc..Microcode section receives slotting packet,
SG hardware list is searched, Fig. 7 is the tabular schematic diagram of SG hardware according to an embodiment of the present invention, as shown in fig. 7, SG sheet format,
It is to table look-up key value with aggregation group ID number, the contents in table corresponding member port information of ID number thus.Look into corresponding to for middle SG table
Port addition/deletion from aggregation group, do not look into middle SG table then by this packet loss.In addition, in order to keep hardware list and soft
The consistency of part cache table content, CPU issue control message to the protocol layer of network processing unit, and protocol layer carries out buffer to ports letter
The update of breath.
Without loss of generality, what consideration line card CPU was got is the information of non-plate aggregation port.Treatment process is as follows: this
Line card CPU interruption reports, and Port interrupts processing function is called to carry out broadcasting slotting packet.The microcode of network processing unit receives slotting packet, sentences
Disconnected is not the port of this line card, this packet broadcast is gone out, and the corresponding first line of a couplet card in distal end completes aggregation port more after receiving this broadcast packet
New operation, and send a notification message.The microcode of network processing unit updates SG hardware list according to notification message.
The embodiment of the present invention, using distribution with interior transmission mode, line card sending port change information is to master control borad, master control
Message is handed down to line card again after being disposed by plate, and line card CPU issues aggregation port and updates information to protocol layer, then by protocol layer
Aggregation port information is configured to these steps of network processing unit, greatly shortens the response time that aggregation port is switched fast,
Packet loss quantity is reduced as far as possible.
