US 7,120,122 B1 · System and method for diagnostic supervision of internet transmissions with quality of service control

Abstract

A system and method are provided for managing diagnostic and performance information for communications system terminal endpoints (TEs) communicating over an Internet Protocol (IP) network. The TEs communicate by transmissions that are voice, modem, facsimile, video, data transmissions, or the like. A Diagnostic Supervisor (DS) transmits Diagnostic Configuration Messages (DCMs) to the TEs. The TEs generate Diagnostic Messages (DMs) based on diagnostic information, including error statistics, voice statistics, facsimile statistics, video statistics, data statistics, or the like, concerning IP network transmissions in which the TEs participate. The DCMs instructs the TEs how to format and when to transmit DMs. The DMs are transmitted by the TEs to the DS. In a system with more than one DS, the TEs can transmit DMS to the plural DSs, other TEs or any network devices.

Dependent claims

A method for managing performance information for a communication between communication system terminal endpoints (TEs) communicating over an Internet Protocol (IP) network, comprising the steps of:

transmitting a Diagnostic Configuration Message (DCM) from a Diagnostic Supervisor (DS) to at least one TE, wherein the DS is capable of being coupled to the at least one TE;
generating Diagnostic Messages (DMs) at the at least one TE based on diagnostic information concerning IP network transmissions in which the at least one TE participates, the DCM instructing the at least one TE how to format and under what criteria to transmit the DMs;
transmitting the DMs from the at least one TE to at least one DS;
and
calculating a value for a quality of service of the communication based on the DMs;
wherein the quality of service is based on communication parameters including at least one of a number of collisions, jitter, amount of lost packets and amount of network usage;
and
wherein the quality of service is further based on weighting the communication parameters, the weighting based on an importance associated with each communication parameter and
wherein the method further includes selectively adjusting one of a plurality of different transmission parameters of each TE via a real time response manager, the adjustments including adjustments to route, parameter thresholds and packet size and wherein the adjustment is made based on the calculated quality of service.
