[SR-Users] Replacing DR Module with Perl Script

Hello Everyone, We are currently using the DR module for routing and failover, and would like to replace it with equivalent functionality using perl script. What we would like is to: * Order the gateways in a strict list given some constraints (Completed) * Build the RURI with the gateway IP, and prefix from the dr_gateways table (Similar to what do_routing does with the FROM tag and dr_gateways information) * Failover to the next gateway in strict order. I would really like to know what our options are, and the most graceful/scalable way of implementing this. PS An example would be highly appreciated! Kind Regards, Nick
