1. A method comprising:

  • deploying in series a plurality of configurable devices in a network, the plurality of configurable devices configured to communicate with one another via a protocol for exchanging state information, wherein a first configurable device of the plurality of configurable devices is in an active state and a second configurable device of the plurality of devices is in a standby state;

    detecting, by the second configurable device, a failure of the first configurable device via a protocol; and

    switching the second configurable device from the standby state to an active state and switching the first configurable device from the active state to a bypass condition when a failure of the first configurable device is detected, wherein the bypass condition allows the same data to flow through both the first and the second configurable devices.
