FAILOVER BASED ON SENDING COMMUNICATIONS BETWEEN DIFFERENT DOMAINS

摘要

A first communication device detects a failure on a communication channel of a primary network. Based on the failure, the first communication device sends communications directed to a second communication device to a secondary network. A secondary network domain controller sends the communications to the primary network via a different communication channel. This can be done by looking at an identifier such as an IP address. This can also happen based on being able to communicate between the secondary network and the primary network via the different communication channel. The primary network then sends the communication to the second communication device. In addition, communications from the second communication device are routed in a similar manner to the first communication device. Sending the communications back into the primary network allows users to have access to features not provided by the secondary network.
