/Relative Fault-tolerant Switching Among Degraded Redundant Communication Paths
Abstract

Aspects of the subject disclosure may include, for example, identifying a current communication path and a group of alternate communication paths extending between the first and second communication devices. The current communication path is configured to support exchanges of information between the first and second communication devices according to a communication service. A partial degradation of the current communication path is detected according to a first degradation severity rating and responsive to the detecting, the first degradation severity rating is compared to a group of alternate degradation severity ratings each corresponding to a respective alternate communication path of the group of alternate communication paths. An alternate communication path of the group of alternate communication paths is selected, for the communication service, having a second degradation severity rating less than the first degradation severity rating. Other embodiments are disclosed.

The current communication path is configured to support exchanges of information between the first and second communication devices according to a communication service. A partial degradation of the current communication path is detected according to a first degradation severity rating and responsive to the detecting, the first degradation severity rating is compared to a group of alternate degradation severity ratings each corresponding to a respective alternate communication path of the group of alternate communication paths. An alternate communication path of the group of alternate communication paths is selected, for the communication service, having a second degradation severity rating less than the first degradation severity rating. Other embodiments are disclosed.
