Test equipment and method of high speed router using web-based operating system {TESTING EQUIPMENTS AND METHODS FOR HIGH SPEED ROUTER USING WEP-BASED OPERATION SYSTEM}

The present invention relates to a test apparatus and a method of a high-speed router using a web-based operating system, and in particular, a web-based operating terminal accesses the high-speed router via a network and selectively selects a plurality of functions of the router. The present invention relates to a test apparatus and a method of a high-speed router using a web-based operating system to perform the test to confirm the test results.

In general, a high speed router (HSR) or HSR-80Gbps accommodates a Gigabit Ethernet interface, a POS interface, and an ATM interface, and provides routing protocol and network management functions in an Internet Protocol (IP) network. It is an edge router based on 80 Gbps high speed LAN.

Such a high-speed router system is installed in a backbone network to connect to an Internet Service Provider (ISP) network, an enterprise network, a campus network, and a gateway router of a server farm. In order to implement a high-speed router system operating in such a backbone network, it is necessary to provide high speed data processing capability and provide QoS, and also provide routing protocol function, statistics management function, fault management function, system configuration management function, IP protocol function, and RMON. Function, operation management function and network management function necessary for system operation and management shall be provided.

In general, a high speed router operating system is classified into a CLI (Command Line Interface) -based operating system and an embedded web server (EWS) -based operating system. It provides a communication window and means between the system and the operator to operate and manage the high speed router. It defines the input / output type of command, dialogue procedure and interaction between high speed router and operator, and performs security management for non-operator's access control and system protection.

However, after designing, developing, and testing such a complicated high speed router, a number of test processes are required until the final quality is recognized. The data required for the test and operation of the high speed router is as large as 140 commands. There are many kinds of data, and these data are used repeatedly for several tens of times, and it is difficult to execute them one by one each time. Since various variable values (parameters) are required, it is very difficult to directly input test data one by one.

FIG. 1 is a diagram illustrating a connection between a test target router and a test system. Referring to FIG. 1, the test configuration of the test target router 10 and the routing test system 15 will be described. Each of the plurality of network connection ports is provided, and the test target router 10 and the routing test system 15 are connected to each other through one-to-one network connection ports.

With this configuration, the tester sets up a network generator to generate as many network topologies as the tester wants, sends information to be recognized by the router under test, and performs routing test for each network topology. It provides a routing test method based on random virtual network generation that allows the test to perform the calculation correctly.

However, such a conventional router tester can only perform a limited test of whether or not the route calculation is correct. Also, since the router and the tester are directly connected, the router tester is connected to the actual network. There is a problem that the router is difficult to test, and also because the test cannot be performed through the network, the router test is inconvenient, difficult and time-consuming.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and therefore, an object of the present invention is to access a high-speed router through a network in a web-based operating terminal and selectively test a plurality of functions of the router. The present invention provides a test apparatus and method for a high-speed router using a web-based operating system capable of confirming test results.

In addition, another object of the present invention is to select the function and class of the high-speed writer to be tested, to perform the test quickly and conveniently, and also to perform a variety of tests with the variable of the test data, according to the system To provide a test apparatus and method for a high-speed router using a web-based operating system that can stabilize the quality and improve quality.

The test apparatus of the high speed router according to the present invention accesses the embedded web server of the high speed router system through the network from the operation terminal using a web-based operating system, and then selects a desired function among various functions of the high speed router system, or a desired class. By selecting, you can test the selected function or class and check the result.

4A and 4B are flowcharts illustrating a method for testing a high speed router system according to the present invention. Referring to FIG. 4A, first, in a first step S41, a high speed router system in an operation terminal 210 that is a client is shown. A function of the fast router system to be tested is selected by accessing the embedded web server 241 embedded in the routing processor 240.

Specifically, after the tester runs a web browser (eg, Internet Explorer 5.0 or higher) in the operating terminal 210, the tester advances to a routing processor board of the high speed router system 240. Access to the embedded web server 241 of the high speed router system 240 using the IP address (URL) specified in the following. After entering the ID and password normally logged in to the web-based operating system using the embedded web server 241 Test modules can be performed. Subsequently, an embedded web server 241 provides a selection menu for a high speed router system test to the operation terminal 210. In this case, a desired function or class is selected in the operation terminal 210.

For example, in order to perform a test for a line interface, each line interface status check test is selected from among various test items included in the selection menu. At this time, each of the functional blocks running in the routing processor RP and the line processor LP in the fast router system 240 should be operating normally.

Next, in a second step S42, necessary system configuration management information is read from the configuration DB 244 for the test of the selection function of the fast router system 240, which is a function of the fast router system 240. The configuration DB 244 managed by the configuration management function unit 243a included in the block 243 is accessed to read data required for the test. The data necessary for the test constitutes all the test data with reference to various design documents, and stores and manages it in the shape DB 244, which is changed in connection with the configuration management function unit 243.

In the third step (S43-S46), the selection information and configuration management information is loaded into the test module to perform the test for the selected function, which is an interface included in the data necessary for the test in the shape DB 244. After retrieving the information, if the data of the interface media, for example, the line interface of slots 2, 9, and 15 are normal, use this information as shown in Table 1 below. Automatically generate test data.

test interface media ge 2/0 test interface media ge 2/1 test interface media ge 9/0 test interface media ge 9/1 test interface media ge 15/0 test interface media ge 15/1

Test data for the six types of interface states as shown in Table 1 above are loaded into the test module. After selecting (or clicking) a test run, the corresponding test data is performed in turn. Here, the test data is test packet data, which is processed according to the unique information for each function classified in advance in the embedded web server 241 and the matching module 242 to be included in the plurality of function blocks 243. The functional part of the functional block 243 performs a test operation.

Next, in the fourth step (S47, S48), the test result data is obtained, classified and stored in a test result DB, which is the data generated through the operation of the corresponding functional unit again as a test data result. In this process provided to the embedded web server 241 via the 242, the test data results are stored in the test result DB 245. If the test data is normally performed in each module, for example, as a result of performing "ge 2/0" in the test interface media, the test data results as shown in Table 2 below can be obtained. As described above, the test result data is classified into functions or classes as selected at the start of the test, and stored in the test result DB 245.

Physical interface ge 2/0 Admin status up Physical link up

Then, in the fifth step (S49, S50) and compares the test result data with the reference data to determine whether it is normal, and stores this judgment information in the test result DB, the test module is a test as shown in Table 2 above In order to check whether the data result is normal, the reference data is read from the test result DB 245, which is stored in advance, which may obtain data related thereto according to the test logic, and the test data result and the reference data may be obtained. In comparison, data as shown in Table 3 below can be obtained.

Name Status Type LP00LP01LP02LP09LP15 noequipnoequipnormal.normal.normal gegege.pos.atm

As described above, after comparing the reference data and the test result data, the result is stored in the test result DB 245 again. That is, as compared with the data shown in Table 3, it can be seen that "Physical link: up" and "LP02 normal ge" are normal.

And finally, in the sixth step (S51) after confirming the end of the test program, if it is before the end proceeds to the third step, if the end is terminated this test, which confirms whether the test logic program is finished and then the test It decides whether to continue or end and handles:

As such, when the test for the function of the desired high-speed router system is normally performed and finished, the test result is stored in the test result DB 245 as shown in Table 4 below.

Line Interface Info Test result Interface Type LP02 OK ge LP09 OK pos LP15 OK ATM

Then, the final test results as shown in Table 4 can be provided to the operating terminal after the test, the embedded web server 241 of the present invention, or a tester or a person connected to the embedded web server 241 The test result (Test Result) can also be confirmed from the test result DB 245 as shown in Table 4 above.

Also, various tests can be performed by varying the test data. Thus, a special effect of stabilizing and improving the quality of the system can be achieved. It is.

Data necessary for the test can be collected from the system configuration management function and the database to exclude more than necessary performance during the test. In addition, since various test data values are managed as a database by using test data from design documents or test procedures, various tests such as exception handling test are possible. Various data can be tested by function at the same time, and various functions can be tested simultaneously by sending data by class.

In addition, the test can be processed in a short time during the manufacture and installation of the high-speed router. Therefore, unlike the existing method, which took a lot of time, it is possible to automatically test for specific functions and classes. Depending on the normal and abnormal operating conditions of the system, testing is possible even during system operation. Data required for testing can be accessed directly from the configuration management database, minimizing the load on the system. By automating the tests, the testing period and testing personnel required for development can be minimized.
