Realize the test of above-mentioned network equipment forwarding performance, a key point is that the n that how to carry out data flow doubly zooms in or out to 1/n.For the concrete means that realize, set forth below:
The n that realizes data flow doubly amplifies, and has three kinds to realize means:
1. the low-speed port of data transmitting/receiving equipment group is received a message, and message is sent into memory, and the processor of data transmitting/receiving equipment group copies n-1 part by message in memory, puts into memory, and now memory has n message, and each message has identical content; Then, processor is each message searching forward-path, refitting encapsulated message head, if the port that the low-speed port of data transmitting/receiving equipment group and high-speed port are same type, processor directly sends n message according to forwarding rule from high-speed port, if the low-speed port of data transmitting/receiving equipment group and high-speed port are not the port of same type, processor re-starts encapsulation after this n message data is partly unpacked, then by forwarding rule, it is sent from high-speed port.
2. the low-speed port of data transmitting/receiving equipment group is received a message, and message is sent into memory, and processor is that this message is found forward-path, refitting encapsulated message head; If the low-speed port of data transmitting/receiving equipment group and high-speed port are same kind port, processor directly copies n-1 part by message in memory, put into memory, now memory has n message, and processor sends this n message by forwarding rule from high-speed port; If the low-speed port of data transmitting/receiving equipment group and high-speed port are not same kind port, processor re-starts encapsulation after this message data is partly unpacked, again message in memory is copied to n-1 part, put into memory, now memory has n message, and processor sends this n message by forwarding rule from high-speed port.
3. the low-speed port of data transmitting/receiving equipment group is received a message, message is sent into memory device, processor is that this message is found forward-path, refitting encapsulated message head, if low-speed port and high-speed port are dissimilar port, processor re-starts encapsulation after this message data is partly unpacked, then by forwarding rule, this message is sent n time from high-speed port; If low-speed port and high-speed port are same kind port, processor directly sends this message n time from high-speed port according to forwarding rule.
Above 3 kinds of amplification methods, from realizing, the 3rd kind of processing procedure that can reduce as far as possible processor, therefore as priority selection method, its realization flow is referring to Fig. 4.In addition, in the 1st, 2 kinds of methods, when processor utilizes first message to copy other message, also can be by the message content except address by similar operations such as certain custom rule add, subtracts to form different messages.
Realize data flow be contracted to 1/n, also have three kinds to realize means:
1. the high-speed port of data transmitting/receiving equipment group is received a message, processor by high-speed port receive telegraph literary composition with memory in existing message contrast, if consistent with existing message content, think that the message of newly receiving is the copy packet of the existing message of memory,, by this packet loss, packet counting is increased to 1 simultaneously; When packet counting is increased to set n (the existing message in memory of take is first counting), processor is that the existing message in memory is found forward-path, refitting encapsulated message head; If low-speed port and high-speed port are not same kind port, processor re-starts encapsulation after this existing message data in memory is partly unpacked, and then by forwarding rule, this message is sent from low-speed port, delete this message in memory simultaneously; If low-speed port and high-speed port are same kind port, processor directly sends this message according to forwarding rule from low-speed port; If cannot find the existing message consistent with the message content of newly receiving in memory, so just this message of newly receiving is deposited in memory, as the source of later message contrast; Because high-speed port receives n message, just from low-speed port, send a message, the method can complete the work that data flow is reduced into 1/n.
2. the high-speed port of data transmitting/receiving equipment group is received a message, and the processor of data transmitting/receiving equipment group is this message searching forward-path, Reseal heading; The processor of data transmitting/receiving equipment group finds whether there be the message consistent with this message content in memory, if existed, abandons the message newly receiving, simultaneously packet counting+1; When packet counting is increased to set n (the existing message in memory of take is first counting), processor judges whether low-speed port and high-speed port are same type port, if low-speed port and high-speed port are not same kind port, processor re-starts encapsulation after this existing message data in memory is partly unpacked, and then by forwarding rule, this message is sent from low-speed port, delete this message in memory simultaneously; If low-speed port and high-speed port are same kind port, processor directly sends this message according to forwarding rule from low-speed port, then deletes this message in memory; If cannot find the existing message consistent with the message content of newly receiving in memory, so just this message of newly receiving is deposited in memory, as the source of later message contrast.
3. the high-speed port of data transmitting/receiving equipment group receives a message, the processor of data transmitting/receiving equipment group by this packet storage to memory; When carrying out packet storage each time, processor all can be added up the number of the message with identical content; While having the message of n identical content in memory, the message that the processor of data transmitting/receiving equipment group is up-to-date reception is found forward-path, Reseal heading; Whether the high-speed port and the low-speed port that judge data transmitting/receiving equipment group are the port of same type, the port of same type if, processor sends the up-to-date message receiving according to forwarding rule from low-speed port, then delete all messages in memory, if be not the port of same type, after the message data of up-to-date reception partly being unpacked, re-start encapsulation, then processor sends the message of up-to-date reception according to forwarding rule from low-speed port, then deletes all messages in memory.
Above 3 kinds are dwindled method, and from realizing, the 1st kind of processing procedure that can reduce as far as possible processor, can save memory space simultaneously, and therefore using it as priority selection method, specific implementation flow process is referring to Fig. 5.In addition, for by the message content except address by similar operations such as certain custom rule add, subtracts to form different messages, can only take the 3rd kind of storage contrast of dwindling in method, again it such as is added, subtracts at similar operations inverse process and restore initial network performance analysis message that equipment sends, this method is had relatively high expectations to processor disposal ability, as do not adopted without special demands.
For " high-speed port " described in the present invention and " low-speed port ", it is the different port of two class speed, the speed of the data flow that " high-speed port " can send or receive with respect to " low-speed port " is higher, equally, for " high-speed data-flow " described in the present invention and " low rate data streams ", be also relative, do not have absolute speed division limits.
