RESILIENT OPTICAL BURST RING FAILURE PROTECTING METHOD, APPARATUS AND FAILURE PROCESSING METHOD

摘要

The present invention relates to the optical communication field, and provides an ROBR fault handling method, including: when a control channel fails, applying the steering mode; when one or more data channels fail, stopping use of the faulty data channels; for normal data channels, continuing use of the normal data channels. Furthermore, the present invention provides a method and an apparatus for ROBR failover. The technical solution under the present invention enables timely and effective handling of the fault of an ROBR network, without delaying packet transmission.
