Embodiment
Below will combine each execution mode shown in the drawings to describe the present invention.But these execution modes do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these execution modes, method or the function all is included in protection scope of the present invention.
Throughput performance test environment in an embodiment of the present invention is as shown in Figure 2, does not need the network tester equipment of specialty, tests between Ethernet switch through embedded throughput performance test processes engine.Particularly, the position of embedded throughput performance test processes engine in Ethernet switching chip is as shown in Figure 3, in order to measure the throughput between the InterWorking Equipment.
Throughput is to describe the basic index parameter of network interconnection device.Definition according to throughput can know that throughput has comprised 2 layers of implication: will guarantee that at first any one Frame to be transmitted can both correctly be forwarded to suitable address, its less important transfer capability of giving full play to equipment.An outstanding feature of network development is the quick growth of network link bandwidth, and being reflected on the network interconnection apparatus, network interconnection is exactly the growth of device throughput, with reference to RFC2544 and ITU-T Y.1564, in the test of throughput, note following some:
(1) testing time:,, just can not correctly reflect the handling capacity of equipment if the time is too short because the measurement of Frame throughput is the transfer capability of equipment under the constant load situation.
(2) test granularity: the test granularity is set at and is no more than 1% of theoretical speed.In the design of actual test system, can adopt the granularity of variation, adopt bigger variation granularity to find the probable ranges of throughput fast when just beginning, select for use more small grain size with accurate location then, general many with two fens algorithms.
(3) test frame length: require a series of frame length (64,128,256,512,768,1024,1280,1518 byte) in the regular hour, is tested by certain number.Frame length is more little, and is big more to the test result influence of throughput, otherwise frame length is big more, more little to the test result influence of throughput.Because for the network equipment; Under same bandwidth; The frame length quantity of small data frame more is just big more; The time of these Frame costs of network device processing will be many more so, otherwise the quantity of the big more Frame of frame length is just more little, and the time of these Frame costs of network device processing will fewlyer also just handle more easily so.
It is as shown in Figure 4 that an embodiment of the present invention is embedded in the flow chart of the throughput performance test processes engine implementation method in the Ethernet switching chip, may further comprise the steps:

The present invention supports a plurality of sessions to carry out the throughput performance test simultaneously; Minimum between each session is given out a contract for a project and is defined as a time scale at interval; If the package processing capability of packet processing engine is the message that each clock cycle can handle 8 bytes; Then sending under the situation of different message lengths, when there was different message length simultaneously in message, 1 needed clock cycle of time scale should be more than or equal to the needed clock cycle of the longest message of length.
Disposing high bandwidth with a business (EVC) below is 10M, is that the message of 64 bytes is treated to example explanation to length under test 100% bandwidth availability ratio.As shown in table 1 below; Core frequency like fruit chip is 200MHZ; Then bandwidth is that 10M and the message that sends 100% bandwidth need 13340 cycles to send a message when chip; The number of supposing the test session of test processes engine support this moment is 16, and the number of the clock cycle of each time scale configuration is 256; Then length is that the time scale number that each session of the test packet of 64 bytes needs is: 13440/16/256=3.28125, and the integer part of sending the time scale number that a message needs this moment is 3; Fractional part is 18432, and (decimal adopts integer representation among this paper, formula: fractional part * 2^16, promptly 18432=0.28125*2^16).

Message processing module (MPM) is in order to add up the byte number and the message number of the data message that receives according to the data structure of test session.
8. the throughput performance test processes engine that is embedded in the Ethernet switching chip according to claim 7 is characterized in that said message sending module specifically is used for:
Throughput performance test processes engine is carried out the initialization assignment;
Wait for overtime expiring of time scale, if there be not overtime expire then to get back to that this continues in step etc. pending;
If overtime expiring judges then whether current test session enables;
If do not enable, then the index to test session upgrades, and obtains the index of next test session and waits for overtime expiring of time scale;
If enable, acquire the data structure of current test session use and obtain a current time scale variable of this session: the time scale timeout value subtracts 1 to the time scale timeout value;
The time scale timeout value is judged, confirmed whether the current sessions time scale expires;
If the current sessions time scale is not yet due, the time scale timeout value in the new session more then, and the index of test session upgraded;
If time scale expires, then externally send a message, the message that needs are sent packages according to configuration, and the message that sends is carried out byte number and bag number statistics, sends to bag forwarding processing engine to message then and handles from the designated port transmission.
9. the throughput performance test processes engine that is embedded in the Ethernet switching chip according to claim 8 is characterized in that, said data structure comprises the configuration of test packet, the statistics and the heading of transmitting-receiving message.
10. the throughput performance test processes engine that is embedded in the Ethernet switching chip according to claim 7 is characterized in that said message processing module (MPM) specifically is used for:
, remote test equipment can whether need loopback to judge after receiving message to message;
If message need be looped back to message source, then exchange the source address and the destination address of message, the outbound port of message is the port of the entering of message, delivers to bag to message then and transmits processing engine;
If message does not need loopback, then further obtain sequence of message number, receive the data structure of counting messages according to the data structure of test session, carry out the inspection of sequence of message number, the byte number and the message number that receive data message are added up.
