Realize the test of above-mentioned network equipment forwarding performance, the n that key point is how to carry out data flow doubly amplifies or is contracted to 1/n.Set forth at concrete realization means below:
The n that realizes data flow doubly amplifies, and three kinds of realization means are arranged:
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 duplicates n-1 part with message in the memory, puts into memory, total n the message of memory this moment, and each message has identical content; Then, processor is sought forward-path for each message, refitting encapsulated message head, if the low-speed port of data transmitting/receiving equipment group and high-speed port are the port of same type, then processor directly sends n message according to transmitting 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, then processor encapsulates after this n message data is partly unpacked again, by transmitting rule it is sent from high-speed port again.
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 sought forward-path, refitting encapsulated message head; If the low-speed port of data transmitting/receiving equipment group and high-speed port are the same kind port, then processor directly duplicates n-1 part with message in the memory, put into memory, total n the message of memory this moment, processor sends this n message by transmitting rule from high-speed port; If the low-speed port of data transmitting/receiving equipment group and high-speed port are not the same kind port, then processor encapsulates after this message data is partly unpacked again, again message in the memory is duplicated n-1 part, put into memory, total n the message of memory this moment, processor sends this n message by transmitting 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 sought forward-path, refitting encapsulated message head, if low-speed port and high-speed port are dissimilar ports, processor encapsulates after this message data is partly unpacked again, by transmitting rule this message is sent n time from high-speed port again; If low-speed port and high-speed port are the same kind port, processor directly sends this message n time from high-speed port according to transmitting rule.
More than 3 kinds of amplification methods, from realizing, the 3rd kind of processing procedure that can reduce processor as far as possible, therefore as priority selection method, its realization flow is referring to Fig. 4.In addition, the 1st, in 2 kind of method, when processor utilizes first message to copy other message, also can be with the message content except that the address by similar operations such as certain custom rule add, subtracts to form different messages.
Realize data flow is contracted to 1/n, three kinds of realization means also arranged:
1. the high-speed port of data transmitting/receiving equipment group is received a message, processor is received telegraph high-speed port, and existing message compares in literary composition and the memory, if it is consistent with existing message content, think that then the message of newly receiving is the copy packet of the existing message of memory, then, simultaneously packet counting is increased by 1 with this packet loss; When packet counting is increased to set n (existing message is first counting in memory), processor is that the existing message in the memory is sought forward-path, refitting encapsulated message head; If low-speed port and high-speed port are not the same kind port, processor encapsulates after this existing message data in the memory is partly unpacked again, and then by transmitting rule this message is sent from low-speed port, delete this message in the memory simultaneously; If low-speed port and high-speed port are the same kind port, then processor directly sends this message according to transmitting rule from low-speed port; If can't find the existing message consistent with the message content of newly receiving in memory, this message that so just will newly receive deposits in the memory, as the source of later message contrast; Because high-speed port receives n message and just sends a message from low-speed port, the method can be finished 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 sought forward-path, encapsulated message head again for this message; The processor of data transmitting/receiving equipment group seeks whether there be the message consistent with this message content in memory, if exist, then abandon the message that newly receives, simultaneously packet counting+1; When packet counting is increased to set n (existing message is first counting in memory), processor judges whether low-speed port and high-speed port are same type port, if low-speed port and high-speed port are not the same kind port, processor encapsulates after this existing message data in the memory is partly unpacked again, and then by transmitting rule this message is sent from low-speed port, delete this message in the memory simultaneously; If low-speed port and high-speed port are the same kind port, then processor directly sends this message according to transmitting rule from low-speed port, deletes this message in the memory again; If can't find the existing message consistent with the message content of newly receiving in memory, this message that so just will newly receive deposits in the memory, as the source of later message contrast.
3. the high-speed port of data transmitting/receiving equipment group receives a message, and the processor of data transmitting/receiving equipment group is stored to this message in the memory; When carrying out the message storage each time, processor all can be added up the number of the message with identical content; When the message of n identical content was arranged in the memory, the processor of data transmitting/receiving equipment group was that the message of up-to-date reception is sought forward-path, encapsulated message head again; Whether the high-speed port of judgment data transceiver group and low-speed port are the port of same type, if be the port of same type, then processor sends the up-to-date message that receives according to transmitting rule from low-speed port, delete all messages in memory then, if be not the port of same type, again encapsulate after then the message data of up-to-date reception partly being unpacked, processor sends from low-speed port according to transmitting the message of rule with up-to-date reception then, deletes all messages in memory again.
More than 3 kinds dwindle method, from realizing that the 1st kind of processing procedure that can reduce processor as far as possible simultaneously can be saved memory space, therefore with it as priority selection method, the specific implementation flow process is referring to Fig. 5.In addition, for message content that will be except that the 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 the 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 higher to the processor processing Capability Requirement, does not adopt as no special demands.
For " high-speed port " described in the present invention and " low-speed port " is the different ports of two class speed, promptly the speed of " high-speed port " data flow that 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 " also is relative, does not have absolute speed and divides boundary.
