Description
Technical field
The present invention relates to a kind of method of testing of IP device throughput, especially a kind of when IP device generation packet loss, set the method for testing of IP device throughput of the transmitted traffic of next round according to the reception flow of epicycle.
Background technology
IP device is the visual plant in the Network Transmission, as router, switch etc., in order to guarantee the good network transmission, need test the performance of IP device.
The throughput of IP device is the main performance index of IP device, also is that the performance of IP device is tested important component part.The throughput of IP device can be divided into absolute throughput and relative throughput, the definition of the absolute throughput of IP device is the maximum quantity of the packet that the IP device unit interval transmits under packet loss prerequisite not, but under different network environments, the throughput of IP device all might be different, and the long throughput of different simultaneously bags also is different.In order to reflect the performance of IP device accurately, introduced relative throughput, relative throughput is defined as absolute throughput and multiply by 100% divided by the theoretical maximum velocity of interface type, for example for the 1000M Ethernet interface, according to the maximum rate of signal transmission and the minimum interval of packet and packet, can calculating in theory, the maximum rate of 1000M Ethernet interface under the long situation of 64 byte packet is 1488095 packets/second.If the absolute throughput of equipment under test 64 bytes is 1200000 packets/second, then the throughput of equipment under test 64 bytes is 1200000/1488095 * 100%=80.64%.Therefore the numerical value of relative throughput is in 0~100% scope.
The testing throughput system of existing IP device, as shown in Figure 1, the user controls testing equipment by control desk, packet to the IP device transmission, after IP device is transmitted, receive and analyze the packet drop that draws the packet that receives by testing equipment, the throughput that the mode of the bag that transmits and receive data by many wheels is come test I P equipment.
Existing IP device throughput testing approach, what mostly adopt is dichotomy, the traversal method of testing with respect to from 0% to 100%, and existing dichotomy is a method of testing efficiently, can test out the throughput of IP device fast and accurately, be to adopt the most general method of testing.The flow process of this method comprises the steps: as shown in Figure 2
When adopting dichotomy to test, need preestablish an initialization flow, the setting of initialization flow needs certain experience, the speed of the quality decision convergence of its setting, but generally speaking, this initialization flow all is made as 100%.As shown in table 1, it has described convergence process and iterations when testing several different relative throughput.
Table 1
Transmitted traffic and relative throughput in the table are percentage, as can be seen from the above table, dichotomy has shortened the iterations of traversal method to a certain extent greatly, but dichotomy still is not a method of testing very efficiently, exist following deficiency: in the reality test, it is very consuming time to utilize dichotomy to test, and a test event need be tested 7~8 performances that bag is long usually, each bag length all needs to carry out iteration convergence, and each pacing examination of iteration convergence all needs 30~60 seconds.Therefore, even under the condition that environment has all mixed up, the test event of a throughput also will be tested nearly half an hour, and testing efficiency is very low.
Summary of the invention
The objective of the invention is deficiency, a kind of method of testing of IP device throughput is provided, reduced iterations, improved testing efficiency by this method at above-mentioned dichotomy existence.
For achieving the above object, the invention provides a kind of method of testing of IP device throughput, this method may further comprise the steps:
Step 1, set maximum, minimum value, precision and the transmitted traffic of relative throughput, the wherein said transmitted traffic quantity of data packets that to be testing equipment send to IP device is divided by the theoretical maximum velocity of interface type;
Step 2, described testing equipment send packet according to described transmitted traffic to described IP device;
Step 3, described testing equipment receive the packet that described IP device is transmitted, calculate and receive flow, and judge whether to take place packet loss, if execution in step 4 then, if not, then execution in step 6, and wherein said reception flow is to receive the theoretical maximum velocity of the quantity of data packets of IP device forwarding divided by interface type in the testing equipment unit interval;
Step 4, judge described transmitted traffic and described minimum value difference whether less than precision, if then execution in step 9, if not, then execution in step 5;
Step 5, described maximum is updated to described transmitted traffic, then described transmitted traffic is updated to described reception flow or described transmitted traffic is updated to the poor of described reception flow and predefined adjusted value, execution in step 2 then;
Step 6, judge described minimum value and described transmitted traffic difference whether less than described precision, if then execution in step 8, if not, then execution in step 7;
Step 7, described minimum value is updated to described transmitted traffic, then described transmitted traffic is updated to half of described maximum and described transmitted traffic sum, execution in step 2 then;
Step 8, described transmitted traffic is set at the relative throughput of IP device, execution in step 10 then;
Step 9, described minimum value is set at the relative throughput of IP device, execution in step 10 then;
Step 10, end.
Wherein in described step 1, described transmitted traffic can be set at 100%.
In described step 5, described transmitted traffic can be updated to the numerical value that described reception flow deducts predefined adjusted value.
The method of testing of IP device throughput provided by the invention has been accelerated the convergence process of testing, and has reduced the iterations of test, thereby has improved testing efficiency.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Description of drawings
Fig. 1 is the testing throughput system schematic of existing IP device;
Fig. 2 is the flow chart of existing dichotomy;
