1. A service management system for a communication network, comprising:
- a plurality of network elements implementing services in a service level agreement (SLA), wherein said service management system determines a set of said network elements constituting a possible cause of degraded quality of one or more services of the SLA, said service management system being adapted to determine the quality of other services of said SLA and to determine said set of network elements as a function of;
the quality of said other services, andnetwork elements utilizing said other services, wherein the network elements of said set are associated with probabilities of being the possible cause of the degraded quality of said one or more services, and wherein said one or more services are directed to voice over internet protocol, and wherein the probability for each network element is determined as a function of the sum of the degrees to which one or more services utilizing said network element are degraded, wherein a relative criteria is established between an average bit rate and a rate of loss of packets for said SLA;
wherein each service is associated with the service level agreement and said degree to which services utilizing said network element are degraded has the value 1 if said service level agreement is not complied with and 0 otherwise.

Abstract
A service management system for determining a set of network elements constituting a possible cause of degraded quality of one or more services determines the quality of other services and determines the set as a function of the quality of the other services and network elements utilizing the other services.

6. A service management system for a communication network, comprising:
-
a plurality of network elements implementing services in a service level agreement (SLA), wherein said service management system determines a set of said network elements constituting a possible cause of degraded quality of one or more services of the SLA, said service management system being adapted to determine the quality of other services and to determine said set of network elements as a function of; the quality of said other services, and network elements utilizing said other services, wherein the network elements of said set are associated with probabilities of being the possible cause of the degraded quality of said one or more services, wherein a value V is calculated for each of said network elements as a sum of a degree of degradation for each of a plurality of said one or more services that utilize each of said network elements, and wherein said one or more services are directed to voice over internet protocol, wherein a relative criteria is established between an average bit rate and a rate of loss of packets for said SLA; wherein each service is associated with the service level agreement and said degree to which services utilizing said network element are degraded has the value 1 if said service level agreement is not complied with and 0 otherwise. - View Dependent Claims (7)

8. A service management system for a communication network, comprising:
-
a plurality of network elements implementing services in a service level agreement (SLA), wherein said service management system determines a set of said network elements constituting a possible cause of degraded quality of one or more services of the SLA, said service management system being adapted to determine the quality of other services of said SLA and to determine said set of network elements as a function of; the quality of said other services, and network elements utilizing said other services, wherein the network elements of said set are associated with probabilities of being the possible cause of the degraded quality of said one or more services, and wherein said one or more services are directed to voice over internet protocol, and wherein the probability for each network element is determined as a function of the sum of the ratio of the number of one or more services handled by said each network element that are degraded to the total number of one or more services that are degraded, wherein a relative criteria is established between an average bit rate and a rate of loss of packets for said SLA; wherein each service is associated with the service level agreement and said degree to which services utilizing said network element are degraded has the value 1 if said service level agreement is not complied with and 0 otherwise. - View Dependent Claims (9)
