Abstract
A system described herein may provide a technique for the seamless failover of devices in a network, such as a wireless telecommunications network. For example, embodiments may identify a particular device, such as a Call Session Control Function (“CSCF”), that has failed or that does not meet particular performance metrics. An Internet Protocol (“IP”) address of the failed device may be assigned to a functioning device of the same type (e.g., another CSCF). The functioning device may be instructed, in accordance with some embodiments, to output routes between itself and other devices or IP addresses, based on which traffic originally intended for the failed device may be routed to the functioning device.
