Detailed Description
So that the manner in which the features and techniques of the disclosed embodiments can be understood in more detail, a more particular description of the embodiments of the disclosure, briefly summarized below, may be had by reference to the appended drawings, which are not intended to be limiting of the embodiments of the disclosure. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may still be practiced without these details. In other instances, well-known structures and devices may be shown simplified in order to simplify the drawing.
The terms first, second and the like in the description and in the claims of the embodiments of the disclosure and in the above-described figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate in order to describe embodiments of the present disclosure. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.
The term "plurality" means two or more, unless otherwise indicated.
In the embodiment of the present disclosure, the character "/" indicates that the front and rear objects are an or relationship. For example, A/B represents: a or B.
The term "and/or" is an associative relationship that describes an object, meaning that there may be three relationships. For example, a and/or B, represent: a or B, or, A and B.
The term "corresponding" may refer to an association or binding relationship, and the correspondence between a and B refers to an association or binding relationship between a and B.
First, the technical terms related to the present application will be explained:
IETF RFC2544: the method is a universal test standard for the current network interconnection equipment, and mainly comprises 4 indexes of throughput, time delay, packet loss rate and back-to-back frame number. In addition, the system recovery and system reset test is also included.
Traffic forwarding ratio: refers to the ratio of the forwardable traffic to the line speed traffic of the network device.
Throughput: refers to the maximum transmission rate of transmitted and received frames by the network device without losing any one frame. It is one of the most important indicators reflecting the performance of the network device. Throughput is generally expressed in two ways, namely, one is expressed in terms of percentage (TP%) and the other is expressed in terms of frames per second (TPpps), and the step of testing the throughput of the network device to be tested by using the method of bipartite approximation in the related art may be shown in conjunction with fig. 1, and includes:
step 101: the test equipment creates an ethernet data frame stream F whose size is initialized to the line speed traffic of the network equipment, i.e. the corresponding TP% equals 100%.
Step 102: the test equipment starts transmitting the ethernet data frame stream F from the transmit port a to the receive port B of the network equipment.
Step 103: after receiving the stream F from the receiving port B, the network device sends the stream F from the transmitting port C to the receiving port D of the test device.
Step 104: the test equipment receives a stream F of ethernet data frames from a receiving port D.
Step 105: after the preset time, the test equipment stops sending the Ethernet data frame stream F and analyzes the receiving and transmitting frames.
Wherein if no frame loss occurs when TP% = 100%, the throughput test is completed and the throughput of the network device is 100%; if there is a frame loss when TP% = 100%, the traffic TP% is turned down from 100% to 50%, and then the process goes to step 102 to retest; if no frame loss occurs when TP% = 50%, the traffic TP% is turned from 50% up to 75%, and then goes to step 102 to retest; if frame loss still occurs when TP% = 50%, the traffic TP% is turned down from 50% to 25% and then goes to step 102 to retest.
Step 106: and repeating the test for a plurality of times, and finally determining the throughput of the network equipment.
Therefore, when the throughput test is performed by using the dichotomy in the related art, the throughput preset value is selected to be relatively traditional and mechanical, so that the iteration test times are excessive, and the geometric multiple is increased by the smaller granularity, so that the efficiency of testing the network equipment is seriously affected.
To this end, as shown in connection with fig. 2, an embodiment of the present disclosure provides a throughput measurement method of a network device, including:
step 201: and sending 100% of line speed traffic to the tested network equipment port, and acquiring a first traffic forwarding ratio of the tested network equipment port under the condition that packet loss exists in the forwarding process of 100% of line speed traffic.
In the embodiment of the application, the test system firstly sends 100% of line speed traffic to the tested network equipment port for throughput test, for example, 1G or 500mb, and judges whether the tested network equipment port has packet loss in the forwarding process of 100% of line speed traffic, at this time, if the tested network equipment port has packet loss in the forwarding process of 100% of line speed traffic, the first traffic forwarding ratio A%, for example, 60%, of the tested network equipment port is obtained; if no packet is lost in the forwarding process of 100% of the line speed traffic, it indicates that the tested network equipment port supports the maximum forwarding rate, and at this time, the first traffic forwarding ratio may be directly determined as the throughput of the tested network equipment port, that is, 100%.
Step 202: and sending a first test flow which is equal to the first flow forwarding ratio to the tested network equipment port, and acquiring a third flow forwarding ratio of the tested network equipment port under the condition that no packet is lost in the forwarding process of the first test flow.
In the embodiment of the present application, when there is a packet loss in the forwarding process of 100% of the line speed traffic, the test system of the present application sends a first test traffic a% equal to the first traffic forwarding ratio a% to the tested network device port to perform a throughput test, for example, 60%, and determines whether the tested network device port has a packet loss in the forwarding process of the first test traffic a%, where if there is no packet loss in the forwarding process of the first test traffic, a third traffic forwarding ratio C%, for example, 60%, of the tested network device port is obtained (because there is no packet loss, the first test traffic a% is equal to the third traffic forwarding ratio C%).
Step 203: and sending a third test flow which is m times the third flow forwarding ratio to the tested network equipment port, and obtaining a fourth flow forwarding ratio of the tested network equipment port, wherein m is a positive number which is larger than 1.
In the embodiment of the present application, under the condition that no packet is lost in the forwarding process of the first test traffic, the test system of the present application further sends a third test traffic m×c% equal to m times of the third traffic forwarding ratio c% to the tested network device port to perform a throughput test, where m is a positive number greater than 1, for example, 1.04, 1.05 or 1.06, and the third test traffic may be 62.4%, 63% or 63.6%, so as to obtain a fourth traffic forwarding ratio d% of the tested network device port.
Step 204: and when packet loss occurs in the forwarding process of the third test flow, and the difference between the fourth flow forwarding ratio and the third flow forwarding ratio is greater than or equal to a preset threshold, sending the fourth test flow which is equal to the fourth flow forwarding ratio to the tested network equipment port, and obtaining a fifth flow forwarding ratio of the tested network equipment port.
In the embodiment of the present application, if the tested network device port still has packet loss during the forwarding process of the third test traffic m×c%, and the difference between the fourth traffic forwarding ratio D% and the third traffic forwarding ratio C% is greater than or equal to a preset threshold, for example, the third test traffic C% is 60%, the fourth traffic forwarding ratio D% is 62% and the preset threshold is 1%, that is (62% -60%). Gtoreq.1%, the test system of the present application further sends a fourth test traffic D% equal to the fourth traffic forwarding ratio D% to the tested network device port for throughput test, for example, 62%, and obtains a fifth traffic forwarding ratio E% of the tested network device port.
Step 205: and under the condition that no packet is lost in the forwarding process of the fourth test flow, determining the fifth flow forwarding ratio as the throughput of the tested network equipment port, or under the condition that the packet is lost in the forwarding process of the fourth test flow, and the difference between the fifth flow forwarding ratio and the third flow forwarding ratio is smaller than a preset threshold, determining the third flow forwarding ratio as the throughput of the tested network equipment port.
In the embodiment of the present application, the test system further determines whether the tested network device port has a packet loss in the forwarding process of the fourth test flow d%, if the flow forwarding has no packet loss, the fifth flow forwarding ratio E% may be determined as the throughput of the tested network device port, for example, in the fourth test flow d% is 62%, and if the flow forwarding has no packet loss, the fifth flow forwarding ratio E% and the throughput of the tested network device port are both 62%; if the packet loss occurs in the traffic forwarding, and the difference between the fifth traffic forwarding ratio and the third traffic forwarding ratio is smaller than a preset threshold, for example, the fifth traffic forwarding ratio E% is 60.99%, the third traffic forwarding ratio C% is 60% and the preset threshold is 1%, that is (60.99% -60%) < 1%, it indicates that the real throughput of the tested network device port is accurately positioned between the fifth traffic forwarding ratio E% and the third traffic forwarding ratio C%, and at this time, the third traffic forwarding ratio C% in the case of no packet loss is determined as the throughput of the tested network device port, that is, 60%.
By adopting the throughput measuring method of the network equipment, which is provided by the embodiment of the disclosure, the real-time flow forwarding ratio of the port of the network equipment to be measured is obtained, so that the set value of the test flow of the throughput is dynamically adjusted, and the flow forwarding ratio corresponding to the dynamically adjusted test flow and the packet loss condition under the current test flow are combined, so that the actual throughput value of the network equipment to be measured is rapidly and accurately tested, and the problem of low throughput test efficiency of the network equipment is effectively solved.
Optionally, as shown in connection with fig. 3, after sending the first test traffic equal to the first traffic forwarding ratio to the tested network device port, the method further includes:
step 301: and under the condition that the packet is lost in the forwarding process of the first test flow, acquiring a second flow forwarding ratio of the tested network equipment port.
In the embodiment of the present application, in step 202, the test system of the present application sends a first test traffic a% equal to the first traffic forwarding ratio a% to the tested network device port to perform a throughput test, for example, 60%, and determines whether the tested network device port has a packet loss during the forwarding of the first test traffic a%, where, if there is a packet loss during the forwarding of the first test traffic, a second traffic forwarding ratio B%, for example, 55%, of the tested network device port is obtained.
Step 302: and iteratively transmitting second test flow which is equal to n times of the second flow forwarding ratio to the tested network equipment port, and obtaining a third flow forwarding ratio corresponding to each generation of the tested network equipment port, wherein n is a positive number smaller than 1.
In the embodiment of the application, the test system of the application is characterized in that the packet loss existsFurther iteratively transmitting a second test traffic n x B% equal to n times the second traffic forwarding ratio B% to the tested network device port for continuous throughput testing, wherein n is a positive number smaller than 1, for example 0.94, 0.95 or 0.96, the second test traffic of the first generation may be 51.7%, 52.25% or 52.8%, and the second test traffic of the second generation may be n 2 * And B, sequentially decreasing the second test flow by exponential times to gradually reduce the second test flow, and acquiring a third flow forwarding ratio C% corresponding to each generation of the tested network equipment port by the test system.

In this way, under the condition that the packet is lost in the forwarding process of the first test flow, the test flow is dynamically adjusted according to the second flow forwarding ratio of the tested network equipment port, so that the lower limit of the real-time flow forwarding ratio of the tested network equipment port without packet loss can be rapidly determined, and the improvement of the efficiency and the accuracy of the throughput test is facilitated.
