Communication apparatus and communication method

摘要

A communication apparatus connected to an adjacent communication apparatus through a first path and a second path to receive a frame with a path identifier through the first path or the second path, the apparatus including: a first network interface configured for communicating via the first path; a second network interface configured for communicating via the second path; and a processor configured for extracting a first monitoring frame and a second monitoring frame, which are failure monitoring frames, from frames received on the first network interface and the second network interface; detecting a failure, based on input monitoring frames; and converting the path identifier of the first monitoring frame or the path identifier of the second monitoring frame, which are extracted, to make the path identifiers equal to each other.

1. A communication apparatus connected to an adjacent communication apparatus through a first path and a second path to receive a frame with a path identifier through the first path or the second path, the apparatus comprising:
a first network interface configured for communicating via the first path; a second network interface configured for communicating via the second path; and a processor configured for extracting a first monitoring frame and a second monitoring frame, which are failure monitoring frames, from frames received on the first network interface and the second network interface; detecting a failure, based on the first and the second monitoring frames; and converting a path identifier of the first monitoring frame or a path identifier of the second monitoring frame, which are extracted, to make the path identifier of the first monitoring frame equal to the path identifier of the second monitoring frame.
