Abstract:
1. A redundant routing system including a processor, the system comprising: a first routing unit configured to manage input data and output data; a second routing unit configured to manage said input data and said output data; a network interface configured to connect said first and second routing units; and a standby bus interface configured to connect said first and second routing units to each other, wherein, when said first routing unit is managing said input data and said output data, said second routing unit detects a failure of said first routing unit by monitoring both the network and the standby bus interfaces using messages sent over both the network and the standby bus interfaces, when said second routing unit detects said failure of said first routing unit, said second routing unit activates a reset algorithm stored in said first routing unit so that said first routing unit no longer manages said input data and said output data and said second routing unit starts managing said input data and said output data, and a memory address of the reset algorithm stored in said first routing unit is stored in a set of parameters stored in at least one configuration file included in said second routing unit.
