Abstract

A network element is identified from among a plurality of network elements to be used to test parameters of a network. The use of one network element to test the network provides more reliable results than using random communications from a plurality of network elements. The test network element is identified using testing pool definitions which may be provided by a network operator. The testing procedure using the single network element may use multiple pings to reduce the affect of transient responses on the network.

Claims

1. An apparatus for monitoring a network comprising:

a microprocessor configured to sort a plurality of network elements according to a network parameter indicative of performance of the network element, to apply a testing pool definition to the plurality of network elements, the testing pool definition specifying configuration parameters identifying network elements suitable for determining performance of the network and removing network elements for consideration as a test network element, to select a network element of the plurality of network elements as a test network element from the network elements identified as suitable for determining performance of the network based on the testing pool definition, and to send a test signal to the test network element; and

a receiver configured to receive a response to the test signal from the test network element,

wherein the apparatus monitors the network using responses to the test signal from only the test network element, which is indicative of the communication parameters of a majority of the network elements of the plurality of network elements, to control a parameter of the network, and

wherein the network communicates with at least a subset of the plurality of network elements via burst communications and a common frequency.

2. The apparatus of claim 1, wherein the plurality of network elements are sorted according to one or more of their:

signal to noise ratio, modulation error ratio, packet error rate, burst error rate, forward error correction error rates, network element transmit level, or signal distortion ratio.

3. The apparatus of claim 1, wherein the testing pool definition includes a percentage of network elements which support a modulation profile.

4. The apparatus of claim 1, wherein the testing pool definition includes the network element with one or more of the lowest:

signal to noise ratio, modulation error ratio, packet error rate, burst error rate, forward error correction error rates, network element transmit level, or signal distortion ratio.

5. A method of identifying a network element to use for testing a network comprising the steps of:

sorting a plurality of network elements based on one or more network parameters;

applying a testing pool definition to the plurality of network elements, the testing pool definition specifying configuration parameters identifying network elements suitable for determining performance of the network and removing network elements for consideration as a test network element; and

selecting a network element from the plurality of network elements identified as suitable for determining performance of the network by application of the testing pool definition as the test network element based on the testing pool definition,

wherein a network uses responses from only the test network element, which is indicative of the communication parameters of a majority of the network elements of the plurality of network elements, to control a parameter of the network, and

wherein the network communicates with at least a subset of the plurality of network elements via burst communications and a common frequency.

6. The method of claim 5, wherein the plurality of network elements are sorted according to one or more of their:

signal to noise ratio, modulation error ratio, packet error rate, burst error rate, forward error correction error rates, network element transmit level, or signal distortion ratio.

7. The method of claim 5, wherein the testing pool definition includes a percentage of network elements which support a modulation profile.

8. The method of claim 5, wherein the testing pool definition includes the network element with one or more of the lowest:

signal to noise ratio, modulation error ratio, packet error rate, burst error rate, forward error correction error rates, network element transmit level, or signal distortion ratio.

9. The method of claim 5, wherein the controlled parameter of the network includes at least one of modulation type, channel frequency, forward error correction configuration, and preamble lengths.

10. A non-transitory computer readable medium carrying instructions for a computer to perform a method of identifying a network element to use for testing a network comprising the steps of:

sorting a plurality of network elements based on one or more network parameters;

applying a testing pool definition to the plurality of network elements, the testing pool definition specifying configuration parameters identifying network elements suitable for determining performance of the network and removing network elements for consideration as a test network element; and

selecting a network element from the plurality of network elements identified as suitable for determining performance of the network by application of the testing pool definition as the test network element based on the testing pool definition,

wherein a network uses responses from only the test network element, which is indicative of the communication parameters of a majority of the network elements of the plurality of network elements, to control a parameter of the network, and

wherein the network communicates with at least a subset of the plurality of network elements via burst communications and a common frequency.

11. The computer readable medium of claim 10, wherein the plurality of network elements are sorted according to one or more of their:

signal to noise ratio, modulation error ratio, packet error rate, burst error rate, forward error correction error rates, network element transmit level, or signal distortion ratio.

12. The computer readable medium of claim 10, wherein the testing pool definition includes a percentage of network elements which support a modulation profile.

13. The computer readable medium of claim 10, wherein the testing pool definition includes the network element with one or more of the lowest:

signal to noise ratio, modulation error ratio, packet error rate, burst error rate, forward error correction error rates, network element transmit level, or signal distortion ratio.

14. The computer readable medium of claim 10, wherein the controlled parameter of the network includes at least one of modulation type, channel frequency, forward error correction configuration, and preamble lengths.
