Abstract: A system and method for connectivity configuration of a network node permits an optical signal to be passed through the node and shifted from a first connector position to a second connector position that is offset from the first connector position. The shifted optical signal permits a number of distant nodes in the network to be reached with a direct optical connection, which can be configured to be bidirectional. The disclosed connectivity configuration reduces the cabling requirements for the network and simplifies the interconnections.

Abstract: Data center network architectures that can reduce the cost and complexity of data center networks. The data center network architectures can employ optical network topologies and optical nodes to efficiently allocate bandwidth within the data center networks, while reducing the physical interconnectivity requirements of the data center networks. The data center network architectures also allow computing resources within data center networks to be controlled and provisioned based at least in part on a combined network topology and application component topology, thereby enhancing overall application program performance.
