The CN2610 includes two LAN ports that can be connected to separate
LAN networks. Using a routing table, the CN2610 can selectively send
packets to different networks. Hosts can also connect to the CN2610
through two different IP addresses and from different LAN networks. A
PC with dual network cards can maintain a connection to the CN2610
through LAN B if LAN A crashes.
In order to reduce the occurrence of single points of failure, different
solutions have been developed for redundancy at the different levels
of a system. “Watchdog” hardware is required to utilize redundant
hardware, and a "Token" switching mechanism is required for the software. The CN2610 supports Dual-host Redundant Data Acquisition
Solution (DRDAS), which is designed for data acquisition applications
that require a high level of redundancy.
The CN2610 is able to maintain simultaneous connections to
both a primary PC and backup PC. If the primary PC becomes
nonresponsive, the backup PC will take control immediately.
