Abstract
Methods and apparatus for providing redundancy in an asynchronous data transfer and source traffic control system include configuring a primary client and a backup client with the same receive address but different transmit addresses. This allows both clients to receive the same traffic flows by utilizing a common receive address while maintaining independent transmit identity allowing each client to communicate with other clients in the system. The methods of the present invention are compatible with a CellBus® system operating in either 16-client mode or 32-client mode.
Claims24
A method for providing redundancy in an asynchronous data transfer and source traffic control system, comprising:
- a) configuring a primary bus client to have a transmit address x and a same receive address x, and
- b) configuring a backup bus client to have a receive address x and a transmit address y, where y is a number different from x;
- c) monitoring the operation of the primary bus client;
- and
- d) transferring operations from the primary bus client to the backup bus client when a primary bus client failure is detected.
An apparatus for providing redundancy in an asynchronous data transfer and source traffic control system, comprising:
- a) a primary bus client configured to have a transmit address x and a same receive address x, and
- b) a backup bus client configured to have a receive address x and a transmit address y, where y is a number different from x.
