Abstract
A data center network node comprising at least one server connection for connecting to a server, a connectionfor connecting the at least one serverto a first subnetwork. The first subnetwork is a conventional subnetwork which comprises at least one of a switch or a router. The node further comprises an optical receiver arrayfor connecting the node to an optical offload subnetwork, wherein the optical receiver arraycomprises a plurality of optical receivers. The array is configured such that each receiver is connectable to an optical path within a multi-path optical connection. The node further comprises an optical transmitter arrayfor connecting the node to an optical offload subnetwork. The optical transmitter array comprises a plurality of optical transmitters. The array is configured such that each receiver is connectable to an optical path within a multi-path optical connection. The node further comprises an electrical switching arrangementfor directing an incoming data stream from a receiver in the receiver arrayto at least one of the at least one server connection to serveror at least one transmitter in the transmitter array, and for directing an outgoing data stream from one of the at least one serverto at least one transmitter in the transmitter array. The electrical switching arrangementprovides for effective transport of data in a data center, e.g. transporting high bandwidth elephant flows on an optical offload network. The electrical switching arrangementenables the provision of point to multipoint connections for data streams by enabling a data stream to be passed to multiple transmitters or received at a node, sent to a server in the node, and transmitted to a subsequent node in the network. Once high bandwidth flow demands have been identified, a schedule of logical links between the nodes of the network is constructed so as to enable the high bandwidth flows to be transmitted on the offload network. The development of the schedule is implemented by an orchestratorand comprises constructing a booking list for high bandwidth flows, wherein a high bandwidth flow is a data stream which has a capacity requirement greater than a threshold.
