Abstract:
In response to a connectivity disruption in an underlying optical transport ring supporting a routing and packet switching topology, one or more of optical devices of the optical transport ring are modified to establish connectivity between spine nodes in different data centers to reroute communication between at least a subset of the leaf network devices so as to traverse an inter-spine route via the optical modified optical transport ring. That is, in response to a connectivity disruption in a portion of underlying optical transport ring, one or more optical devices within the optical transport ring are modified such that packets between at least a portion of the leaf devices are rerouted along optical paths between at least two of the spine network devices.

Claim (Index 10):
A distributed data center system comprising:\n a first spine network device in a first data center having a first set of leaf network devices; a second spine network device in a second data center having a second set of leaf network devices; an optical transport ring having a first optical path, wherein, in the distributed data center system, the first set of leaf network devices of the first data center communicate with the second set of leaf network devices of the second data center via a single one of the first spine network device of the first data center or the second spine network device of the second data center, and wherein the first optical path is for transporting packets from the first spine network device of the first data center to the at least one leaf network device of the second data center prior to a disruption along the first optical path; one or more packet-optical transport devices that interconnect the optical transport ring to the first and second spine network devices and the first and second set of leaf network devices; and processing circuitry configured to:\n determine that connectivity, through the first optical path of an optical transport ring, between the first spine network device of the first data center and at least one leaf network device of the second set of leaf network devices of the second data center is disrupted, wherein the first optical path in unavailable after disruption; \n in response to the connectivity disruption, configure one or more of the packet-optical transport devices of the optical transport ring to establish direct connectivity between the first spine network device and the second spine network device to reroute packets to be transmitted, via the first optical path, to the at least one leaf network device of the second data center, wherein the reroute of the packets is via a second optical path of the optical transport system from the first spine network device to the second spine network device; and \n cause the first spine network device to communicate the packets to the at least one leaf network device of the second data center through the second optical path.
