  • Network element with dual independent sub network elements with seamless failover
    Patent number: 11558240
    Abstract: A system that provides communication services may include two switches for redundancy. The switches may indicate that they are independent devices to upstream devices and indicate that they are the same device to a predetermined device set. If one of the switches enters an undesired state, then the switch in a standby state may modify the upstream devices to preferentially forward packets directed toward the predetermined device set to the standby switch rather than an active switch, and after transitioning the active switch to the standby state, transition the standby switch to the active state.
