Abstract
In one embodiment, a plurality of communication paths in a second direction in a communication network is determined, based on reversing communication paths established in a first direction in the communication network. Then, a path quality of the communication paths in the second direction is monitored. Based on the monitored path quality, it is then determined whether the communication paths in the second direction satisfy a communication requirement. Finally, a particular communication path of unacceptable quality in the second direction is detected when the particular communication path in the second direction fails to satisfy the communication requirement.
Claims25
A method, comprising:
- determining, based on reversing communication paths established in a first direction in a communication network, a plurality of communication paths in a second direction in the communication network;
- monitoring a path quality of the communication paths in the second direction;
- determining, based on the monitored path quality, whether the communication paths in the second direction satisfy a communication requirement;
- and
- detecting a particular communication path of unacceptable quality in the second direction when the particular communication path in the second direction fails to satisfy the communication requirement.
An apparatus, comprising:
- one or more network interfaces that communicate with a communication network;
- a processor coupled to the one or more network interfaces and configured to execute a process;
- and
- a memory configured to store program instructions which contain the process executable by the processor, the process comprising:
- determining, based on reversing communication paths established in a first direction in the communication network, a plurality of communication paths in a second direction in the communication network;
- monitoring a path quality of the communication paths in the second direction;
- determining, based on the monitored path quality, whether the communication paths in the second direction satisfy a communication requirement;
- and
- detecting a particular communication path of unacceptable quality in the second direction when the particular communication path in the second direction fails to satisfy the communication requirement.
A tangible non-transitory computer readable medium storing program instructions that cause a computer to execute a process, the process comprising:
- determining, based on reversing communication paths established in a first direction in a communication network, a plurality of communication paths in a second direction in the communication network;
- monitoring a path quality of the communication paths in the second direction;
- determining, based on the monitored path quality, whether the communication paths in the second direction satisfy a communication requirement;
- and
- detecting a particular communication path of unacceptable quality in the second direction when the particular communication path in the second direction fails to satisfy the communication requirement.
