Description

Ethernet traffic multiplier

This creation is about an Ethernet traffic multiplier, especially an Ethernet traffic multiplier that can generate traffic of various network bandwidth specifications.

According to the increasing use of the network, the performance and quality of related network equipment has become an increasingly important issue for the industry. For the development of network switches, operators usually use network switches. (ie, the device under test (DUT)) is tested for traffic, so that the performance of the network switch at various rates of network traffic can be obtained.

In order to achieve the aforementioned test behavior, the tester usually uses a test device capable of simulating different rate flows, for example, Smartbits/IXIA, which has an output port of 10 Gbit/s, 1 Gbit/s and 100 Mbit/. s, etc., to simulate the network traffic of the aforementioned rate, therefore, such test equipment is also called a network performance analyzer or a network traffic simulator. However, due to the explosive growth of the Internet population, and people's daily work and leisure and entertainment are increasingly relying on the Internet, in order to meet people's needs, 10G network switches are gradually emerging, meaning that for 10Gbit /s The demand for high-speed traffic is increasing. However, under the existing technology, the 1Gbit/s output port of the test equipment can only perform 1G port performance and traffic test on the network products under test, but cannot be completed. 10G's performance and traffic test, which means that the industry can only complete the high-speed traffic measurement required for the network products under test by purchasing more test equipment. test.

With the development of network switch technology, future network switches are bound to have ports of 40G, 100G or higher, which will cause operators to continuously purchase new test equipment to be able to measure the network. Road products are tested for high-speed traffic. Because the circuit structure of existing test equipment is quite complicated and expensive, and individual output ports can only simulate the flow of a single network bandwidth specification, it will cause low speed on the test equipment. (For example: 1Gbit/s and 100Mbit/s) The output port is idle.

In summary, how to effectively solve the above problems, in order to provide more convenient and no need to pay high money to purchase a large number of test equipment, has become an important goal that many operators are trying hard to develop and want to achieve.

In view of the low speed (eg 1Gbit/s and 100Mbit/s) output ports on the test equipment, it is usually idle, and the high-speed (eg 10Gbit/s) output ports are limited, which leads the industry to meet the R&D test. Demand, but the need to continuously purchase test equipment, causing the operator's money expenditure is too heavy, so after long-term efforts and experiments, the creator finally developed and designed an Ethernet traffic multiplier of this creation, with the hope of the creation of this creation, Can effectively solve the aforementioned problems.

One of the purposes of this creation is to provide an Ethernet traffic multiplier that is applied to a device under test to analyze the high-bandwidth network performance of the network product under test and The test can be used to adjust the high-frequency wide network traffic transmitted to the network under test, the multiplier includes an Ethernet switch chip, wherein the Ethernet switch chip has a plurality of input ports and a plurality of Output 埠, the specifications of the input 属于 belong to a first specification, the first specification can be used to transmit a reference bandwidth network traffic, the input system and the network The corresponding output of the circuit device is connected to receive the network bandwidth of the reference bandwidth transmitted by the network device, and the specifications of the output devices belong to a second specification, and the second specification can be used for transmission multiplication The bandwidth of the network traffic, the network traffic of the multiplying bandwidth is n times of the network traffic of the reference bandwidth, where n>1, and the output ports are corresponding to the input of the network product to be tested. Connecting, to copy the network data of the reference bandwidth network traffic by n times on the Ethernet switching chip, and then transmitting the network data of the generated multiplication bandwidth network traffic to the waiting Measure network products and analyze and test the high-bandwidth network performance of the network products under test. Thus, the created Ethernet traffic multiplier can replace the traditional network traffic simulator. The traditional network traffic simulator not only has a complicated circuit structure and is expensive, but also can simulate the flow of a single network bandwidth specification, and cannot adapt to various high-frequency and wide-network performances that are generated by the rapid development of network switch technology. Network products to be tested

Another object of the present invention is that the multiplier further comprises a central processing unit, wherein the central processing unit is respectively connected to the Ethernet switching chip, at least one input device and/or at least one output device, the central The processing unit can set the n times value according to a tester through the input device to adjust a multiple of the network data of the network traffic of the Ethernet switching chip to copy the reference bandwidth, and the central processing unit Network data of the network bandwidth of the reference bandwidth input to the Ethernet switch chip, and/or network data of the multiplied bandwidth network traffic output by the Ethernet switch chip, Transfer to the output device for the tester to view, so that the tester can adjust the n times value to meet various test needs.
