Handling unacceptable asymmetrical communication paths in computer networks

摘要

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.

1. 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 to determine a presence of an asymmetric path; determining, based on the monitored path quality, whether the communication paths in the second direction satisfy a communication requirement and whether the communication paths are asymmetric; detecting an asymmetric communication path of unacceptable quality in the second direction when the particular communication path in the second direction fails to satisfy the communication requirement; in response to detecting the asymmetric communication path of unacceptable quality in the second direction, determining whether an alternative next-hop selection of a remote node exists that would remove the asymmetric communication path of unacceptable quality; and in response to determining that the alternate next-hop exists, modifying the alternative next-hop selection of the remote node.
