Distributed protection switching architecture for point-to-point microwave radio systems

摘要

A system and method for protecting a received data stream. Active receivers and standby receivers are provided, each adaptable to receive a data stream on a traffic channel. Plural data processing units are operatively in communication with the receivers. At least one of the plural DPUs provides a switching signal to the receivers to switch the state of the active receiver to standby and the state of the standby receiver to active as a function of a quality measurement of the received data stream via the traffic channel.

1. A method, comprising:
receiving a data stream by a first receiver having an active state and a standby state, the first receiver being in the active state; receiving the data stream by a second receiver, the second receiver having an active state and a standby state, the second receiver being in the standby state; measuring by the first receiver a characteristic of the data stream to generate a first quality measurement; measuring by the second receiver the characteristic of the data stream to generate a second quality measurement; providing a quality signal to one or more data processing units (DPUs), the quality signal being a function of the first quality measurement and the second quality measurement; and generating by the one or more DPUs a switching signal configured to switch the first receiver from the active state to the standby state and to switch the second receiver from the standby state to the active state, the switching signal being based on the quality signal.
