The effect of ATCA cabinets is that backplane channel, wherein power board are powered and provided to each business board in the present invention
Effect be to provide final business physical interface and converge the business data flow, wherein business board of disengaging effect be do flow turn
Hair and the processing of tunnel traffic and various access service, the effect of wherein master control borad are configurations with monitoring whole set equipment and synchronous
Forwarding cache information table between different business plate.
Separation and reasonable cloth of the stationary problem of business datum by control and management plane and message Forwarding plane between board
Office realizes；The problem of load balancing is distributed between board stacks agreement to realize by the tactful forwarding capability and Higig of power board.
It is to be stacked by one kind that company of Botong (broadcom) realizes in its exchanger chip for multiple chips that Higig, which stacks agreement,
A kind of technology.In the explanation of the present invention stacking agreement that uses using Higig agreements as concrete implementation in a manner of, if specifically
Scheme has used the exchanger chip of other manufacturers in realizing, then can use corresponding stacking agreement.
Business board only carries out Message processing according to current business forwarding cache information, once can not the match is successful to weigh
Orient message and carry out complete complete trails forward process to master control borad.This design is a material facts according to network traffics
Carry out, 99% network traffics are all IP operation bag and forwarding strategy inside gateway device and path is identical.Institute
So that business board can be directly according to the most of network traffics of contents processing of business forwarding cache information table.
As shown in figure 4, the design of present ATCA business boards can reach higher density, usually can be in a business board
Two high performance CPU processors of upper placement.In order to allow two CPU processors of a business board can be with parallel processing business report
Text, distribution service forwarding cache information table can be unified by master control borad using single CPU processor as logic business plate.In addition,
In order to ensure service message is accurately redirected to from the port of power board the CPU processor of certain business board, it is not necessary to be concerned about
The path of backboard and the exchange process of centre using Higig on the interface of board interconnected, it is necessary to stack agreement.Soft
The process of part system initialization is that each exchanger core blade unit and CPU processor unit distribute independent MODID (module volumes
Number), Higig stacks target MODID of the agreement internally on interconnecting interface directly according to message and forwarded.Software is that complete machine is each
Each processing unit of individual board is assigned with independent MODID.Should at the port that the exchange chip message of power board enters
With forwarding strategy, the message to receive specifies target MODID, and such service message will stack the effect of agreement in Higig
Under successfully reach corresponding to business board CPU processor.Wherein logic business plate is the virtual management object of software, and load is equal
The method of accounting will be that each logic business plate distributes rational processing task.
Load-balancing algorithm between each logic business plate can have a variety of implementation methods, and in general way has static thing
Manage port binding logic business plate, dynamic physical port binding logic business plate, certain is redirected to according to message source IP cryptographic Hash
Open logic business plate, certain logic business plate is redirected to according to message purpose IP cryptographic Hash.From the result of application process feedback
See, the loading algorithm of dynamic physical port binding logic business plate is optimal implementation.
The loading algorithm of dynamic physical port binding logic business plate, refer to the management chain of command of master control borad according to power board
Panel physical port Link-UP events dynamically for it distribute and binding logic business plate processing unit.According to this calculation
Method, the power board panel physical port of first Link-UP (insertion netting twine connects with other network equipments), will be assigned to first
Logic business plate processing unit is opened, the like.The fact that this algorithm, is according to being the panel physical port energy of usual power board
The data rate of support is 10Gbps or 40Gbps, and the data that a corresponding high performance network processing unit can forward
Handling capacity more than 10Gbps or 40Gbps, can be true so binding a logic business plate (CPU processor) for physical port
The forwarding of guarantor's business is smoothed out not packet loss.
As shown in Fig. 2 after message enters whole set equipment, power board is arrived first at.Power board carries out preliminary screening to message,
IP messages are delivered to corresponding business board according to load-balancing algorithm, and non-IP messages (being typically ARP messages) are delivered to master control borad.
After IP messages reach business board, five critical fielies, and existing cache information table are extracted in the header information of message
Lookup matching is carried out, message conversion and transmission are carried out according to the content of forwarding cache information table if matching, if do not had
Match, be delivered to master control borad and carry out fullpath forwarding and caching information learning.Forwarding surface is based on forwarding on business board
Cache information is forwarded, and the IP header informations and mac header information of message, some data are replaced according to the content of cache information
Stream will also carry out the encrypt and decrypt operation of message data content according to the IPsec key informations of caching.Forwarded on master control borad
Face carries out the processing of layer two MAC header information, three layers of IP header information to message respectively according to the processing mode of ICP/IP protocol stack
Processing, four layers of TCP/UDP header informations processing.The forward process process of fullpath is being carried out, if it find that the report of a certain layer
The abnormal then dropping packets of header simultaneously do abnormal information log recording, if it find that the final destination address of message be this equipment then
Text delivery is further processed to corresponding management chain of command application program.If whole fullpath forward process is smooth
Complete, message is finally sent from some service port, then records the forwarding cache letter of the data flow corresponding to this message
Breath.
The invention has the advantages that：
Effect one, realize that the small base station access networks of LTE Smallcell of the more board unified management parallel processings of complete machine close production
Product, it is set to easily facilitate use.
Effect two, because business board business forwarding cache synchronizing information forms mutual redundancy backup, improve system and production
The reliability of product, individual business board hardware fault is avoided to cause network interruption.
Effect three, dynamically gateway product can be expanded according to forwarding loading condition and electric power energy service condition
Hold or power-save operation, business board can realize flexibly expansible gateway product with hot plug.
Although the foregoing describing the embodiment of the present invention, those familiar with the art should manage
Solution, the specific embodiment described by us are merely exemplary, rather than for the restriction to the scope of the present invention, are familiar with this
The equivalent modification and change that the technical staff in field is made in the spirit according to the present invention, should all cover the present invention's
In scope of the claimed protection.
