Description
Technical field
The present invention discloses a kind of method of test network bandwidth, belongs to cluster network field tests, specifically a kind of method based on test network bandwidth under the cluster environment of shell.
Background technology
The network bandwidth refers within a regular time (1 second), by maximum number of digits certificate.Current operation one or more computer in a local network and database management system software together constitute data server, data server provides service for Client application, along with the generation of large data age, it has certain difference on data pressure and network bandwidth requirements, along with the change of time, also will there is certain change in data pressure and network bandwidth requirements.And the network bandwidth is as the important indicator weighing Internet Use, be day by day subject to the common concern of people.It is not only the important evidence of government or unit formulation network service development tactics, is also that one of principal element of Internet access service business is selected by Internet user and unit.During the network bandwidth under current test computer cluster environment, because node is numerous, the factors such as the network port enormous amount that need test, disposes difficulty, unified operation inconvenience, affect testing efficiency greatly.In order to make up the disappearance of this respect testing tool and method of testing, realize special under cluster environment, a unified remote control terminal deployed environment, accurately test, the invention provides a kind of method based on test network bandwidth under the cluster environment of shell, by the parameter preset of test, automatically perform test, function such as conclusion logging test results etc., without the need to lengthy and jumbled result treatment, realization operates, it is simple and easy to run, omnidistance unattended operation; Can predefined parameter before test, apply unrestricted; The data of record are detailed, grasp test machine situation by data; Solve at present under cluster environment because node is numerous, dispose difficulty, the problem of the disappearance of the testing method and tool that the factors such as unified operation inconvenience cause, possesses very strong applicability, be applicable to the type be generalized to widely under various cluster environment, greatly improve testing efficiency.
Summary of the invention
When the present invention is directed to the network bandwidth under current test computer cluster environment, because node is numerous, the network port enormous amount that need test, dispose difficulty, the factors such as unified operation inconvenience, affect the problem of testing efficiency greatly, a kind of method based on test network bandwidth under the cluster environment of shell is provided, be applicable to current linux operating system, realize operation, run simple and easy, omnidistance unattended operation; Can predefined parameter before test, apply unrestricted; The data of record are detailed, grasp test machine situation, possess very strong applicability by data, are applicable to being generalized to widely the type under various cluster environment, greatly improve testing efficiency.
The concrete scheme that the present invention proposes is:
Based on a method for test network bandwidth under the cluster environment of shell, concrete steps are:
1. environmental test: ensure that all nodes are in a cluster environment, and all nodes are based on the operating system of linux kernel; The network port for all nodes carries out checking that whether state in place is normal, and to effective port distributing IP address, checking is connective;
2. under cluster environment, under test program and iperf, netperf being copied to any file of operating system; All Joint Enterprise are that ssh exempts from code entry environment, all can carry out operational administrative to all nodes from any node, then to all nodes and the sequence of overall network port;
3. the parameter of all nodes is pre-seted;
4. the parameter pre-seted is checked whether be satisfactory parameter preset, test run environment checked, with or without the test environment met the demands;
By an all node of node remote operation when 5. running, according to the parameter pre-seted satisfied condition, different node, heterogeneous networks port are carried out respectively to the test of the network bandwidth, each test result according to sequence of event in test record; As the situation that Internet Transmission interrupts detected, timely output display, marks according to node sequence and network port sequence;
6. result treatment: concluding process further according to node sequence, the test file created in clear program running to testing the result drawn, terminating test.
Described step 3. in pre-set all nodes parameter comprise the overall network port IP address of all nodes, the transport block size needed for test network bandwidth, test required time, host-host protocol.
Described step 3. in the host-host protocol that pre-sets be TCP, UDP two kinds of host-host protocols, carry out loop test.
Usefulness of the present invention is: this method of testing is mainly realized by test program, has parameter preset, automatically performs test, concludes the functions such as logging test results.Without the need to lengthy and jumbled result treatment, greatly save the testing time, improve testing efficiency.Make up at present under cluster environment because node is numerous, dispose difficulty, the defects such as the disappearance of the testing method and tool that the factors such as unified operation inconvenience cause; Operation, run simple and easy, omnidistance unattended operation, possesses very strong applicability, is applicable to being generalized to widely the type under various cluster environment.
Embodiment
The test machine setup test of some the network switchs and some installation linux operating systems, software test is surrounded by: iperf, netperf Wireless Test Toolset, can test under general room temperature.
Based on a method for test network bandwidth under the cluster environment of shell, concrete steps are:
1. environmental test: ensure that all nodes are in a cluster environment, and all nodes are based on the operating system of linux kernel; The network port for all nodes carries out checking that whether state in place is normal, and to effective port distributing IP address, checking is connective;
2. under cluster environment, under test program and iperf, netperf being copied to any file of operating system; All Joint Enterprise are that ssh exempts from code entry environment, all can carry out operational administrative to all nodes from any node, then to all nodes and the sequence of overall network port;
3. the parameter of all nodes is pre-seted; Comprise the overall network port IP address of all nodes, the transport block size needed for test network bandwidth, test required time, host-host protocol; The host-host protocol pre-seted is TCP or UDP two kinds of host-host protocols, carries out loop test;
