Robustness And Network Resilience of Devices
This article describes the behavior of devices supported by the OMNITOTAL service in the case of a gateway and registration service degradation in the OMNIVIGIL infrastructure. The OMNIVIGIL infrastructure is redundant and provides secondary gateways/proxies. The following table describes the behavior of the devices in case of a degradation or unavailability of the primary gateway.
| Behavior | Details |
| Excellent |
If the primary gateway fails, the device will detect the failure within 90 seconds and automatically migrate to the secondary gateway. When the device migrates to the new gateway, a new SIP REGISTER is transmitted to update the SIP link to the infrastructure, making the devices immediately available. When the primary gateway becomes available again and is detected by the device (typically 5-10 minutes), the device will switch to it immediately or to the next SIP REGISTER. |
| Average |
These devices do not detect any gateway failure except on a SIP REGISTER sequence. If the gateway fails, the device will reconnect after the current SIP REGISTER expires, which can take up to 60 minutes. These devices will detect a failed gateway at startup. Therefore, rebooting the device will force the failover. When the primary gateway becomes available again, the device will failover to it the next time the SIP REGISTER expires. |
| Low | These devices do not support gateway redundancy, even when rebooted. |
