Appear systems allow operators to determine redundancy, maintenance and repair strategy appropriate for their operations, their customer base and services offered.
The IP output redundancy system presents a network with multiple sources from which it is possible to obtain the same service. Should the service from one source be corrupted, the network can receive the service from another source.
For a full redundancy scenario, identical Appear chassis can be configured to receive, process and stream identical services. In a typical deployment, a service is broadcast from two locations using the same IP multicast source address. As long as all sources have the same IP source address, the network will route just a single copy of the multicast stream forward to the receiver. In the event of a service issue within, or prior to, the Appear chassis, the IP output module exploits standard IP protocols to trigger external routers to switch to secondary sources.
Where full redundancy is not required, partial redundancy strategies can be implemented. Systems can be configured to provide full redundancy of only selected premium or ‘must-carry’ services. Operators can then choose not to replicate the input and descrambling functions of lower priority services, but still equip the chassis with multiple IP output modules to provide limited fault tolerance.
