Automatically configuring a distributed network analyzer to monitor identified inverse multiplex groups of an asynchronous transfer mode network
View Patent ↗A method and apparatus of automatically identifying IMA links of an asynchronous transfer mode network and automatically configuring a distributed network analyzer to monitor the identified IMA links. Information is selectively extracted from streams of cell data exchanged across an asynchronous transfer mode network to automatically identify IMA links of the asynchronous transfer mode network, and automatically configuring a distributed network analyzer to monitor the identified IMA links. A graphical user interface is provided to display status information of the automatically identified IMA links of an asynchronous transfer mode network based on monitoring of the identified IMA links using a distributed network analyzer automatically configured to monitor the identified IMA links.
1. A method, comprising:
automatically differentiating IMA (inverse multiplexing over asynchronous transfer mode) data from other ATM data transmitted on a plurality of links in an asynchronous transfer mode network for identifying IMA links of the asynchronous transfer mode network; and
automatically configuring a distributed network analyzer to monitor only the identified IMA links;
wherein the automated identification of the IMA links includes indicating corresponding IMA groups of each of the IMA links;
displaying status information of the monitored IMA links;
wherein the status information includes data indicative of loss of signal, loss of frame and header control error of each of the IMA links.
2. The method according to claim 1 , wherein the automated identification of the IMA links is initiated in response to a single command by an end user.
3. The method according to claim 1 , wherein the status information indicates when a number of the identified IMA links does not match a predetermined number of IMA links.
4. The method according to claim 1 , wherein the status information indicates an error rate for each of the indicated IMA groups.
5. The method according to claim 1 , wherein the automatically configuring the distributed network analyzer further comprises determining status information of the IMA links.
6. The method according to claim 1 , wherein the step of automatically differentiating IMA data from other ATM data includes determining whether IMA control protocol cells (ICP) have arrived at predetermined intervals.
7. A method, comprising: selectively extracting information from streams of cell data exchanged across an asynchronous transfer mode network to differentiate IMA (inverse multiplexing over asynchronous transfer mode) data from other ATM data transmitted on a plurality of links in an asynchronous transfer mode network for identifying IMA links of the asynchronous transfer mode network; and
automatically configuring a distributed network analyzer to monitor only the identified IMA links;
wherein the automated identification of the IMA links includes indicating corresponding IMA groups of each of the identified IMA links;
displaying status information of the IMA groups monitored by the distributed network analyzer;
wherein the status information includes data indicative of loss of signal, loss of frame and header control error of each of the IMA links.
8. The method according to claim 7 , wherein said automatically configuring comprises: selectively configuring the distributed network analyzer to monitor a selected portion of the indicated IMA groups.
9. The method according to claim 7 , wherein the status information indicates when a number of the identified IMA links does not match a predetermined number of IMA links.
10. The method according to claim 7 , wherein the automated identification of the IMA links is initiated in response to a single command by an end user.
11. The method according to claim 7 , wherein the status information indicates link identification data of the IMA links and group identification data of the corresponding IMA groups.
12. The method according to claim 7 , wherein the automatically configuring the distributed network analyzer further comprises determining status information of the IMA links.
13. The method according to claim 7 , wherein the step of automatically differentiating IMA data from other ATM data includes determining whether IMA control protocol cells (ICP) have arrived at predetermined intervals.
