Abstract

Reporting tools used to manage an asynchronous transfer mode (ATM) network. Tools include a trunk inventory reporting tool, a trunk utilization reporting tool, an exceptions reporting tool and a flow control processor activation utility. Reports generated by these the tools include information about the operation and capacity of trunks, switches and user network interfaces.

Claims

1. A computer system for generating a trunk inventory report for managing trunks terminated on an ATM switch, comprising:

a server, in communication with the ATM switch and a network management information database, wherein the server is operative to execute an application program, and wherein the application program is operative to generate the trunk inventory report, the trunk inventory report comprising;

a header section including at least one of a report title, a report date, a switch name for the ATM switch, a switch IP address for the ATM switch, and a number of trunks terminated on the ATM switch; and

a body section including a plurality of fields for each trunk terminated on the ATM switch, wherein the plurality of fields includes a first plurality of data gathered from a switch management database and a second plurality of data gathered from the network management information database, wherein the first and second pluralities of data are organized according to a predetermined format and wherein the plurality of fields provide information about each of a first end and a second end of each trunk, wherein the plurality of fields further includes a bandwidth field for identifying the bandwidth of each trunk, wherein the bandwidth is the larger of a first bandwidth of the first end of each trunk and a second bandwidth of the second end of each trunk, wherein the plurality of fields further includes a traffic type field for identifying a type of traffic allowed over an interswitch trunk, wherein the traffic type indicates the allowance of at least one of user data and management traffic over the interswitch trunk, wherein the plurality of fields further includes an administrative cost field for identifying an assigned cost for each trunk,

wherein the trunk inventory report generated by the computer system is utilized to route circuits over trunks having the lowest administrative costs, determine a trunk status, and enable a report user to execute correction processes for an offending trunk.

2. The computer system of claim 1, wherein the first plurality of data includes a trunk name, and the plurality of fields comprise data values associated with a trunk-end terminated on a second ATM switch.

3. A computer system for generating a trunk utilization report for managing trunks terminated on an ATM switch, comprising:

an application program executing on the computer system, wherein the application program is operative to generate the trunk utilization report, the trunk utilization report comprising;

a header section including at least one of a report title, a report date, a switch name for the ATM switch, a switch IP address for the ATM switch, a period start date for the report and a period end date for the report; and

a body section including a record for each trunk terminated on the ATM switch, wherein each record includes a first plurality of data gathered from a switch management database, a second plurality of data gathered from a network management information database and a utilization rate, wherein the first and second pluralities of data are organized according to a predetermined format, wherein the second plurality of data includes a cells incoming value representing a number of cells incoming to a logical port at the end of each trunk at the end of a period minus a number of cells incoming to the logical port at the beginning of the period and a cells outgoing value representing a number of cells outgoing from the logical port at the end of the period minus a number of cells outgoing from the logical port at the beginning of the period, and wherein the utilization rate is based on the cells incoming and cells outgoing values, wherein the utilization rate for each trunk is calculated by dividing the cells incoming value minus the cells outgoing value by a duration of the period divided by a trunk bandwidth,

wherein the trunk utilization report is periodically generated by the computer system to provide traffic statistics for each trunk terminated on the ATM switch.
