The following quote was obtained by the news editors from the background information supplied by the inventors: "Some embodiments described herein relate generally to large data centers and enterprise networks, and, in particular, to methods and apparatus for providing services in a distributed switch within, for example, a single-layer data center.
"Some known data centers arrange network devices in a way such that a typical three-layer architecture (e.g., an access layer, an aggregation layer and a core layer) can be collapsed into a single-layer architecture. In such single-layer architecture, multiple edge devices such as top-of-rack (TOR) network devices are interconnected by multiple links. The TOR network devices are connected to multiple server devices that provide various functions and services for components of the data center.
"A need exists, however, for methods and apparatus that can efficiently provide the functions and services in data centers of the single-layer architecture."
In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "In some embodiments, a non-transitory processor-readable medium stores code to cause a processor to receive, from a source peripheral processing device, a portion of a data packet having a destination address associated with a destination peripheral processing device. The code causes the processor to identify, based on at least in part on the destination address, a service to be performed on the portion of the data packet. The code causes the processor to select, based on the service, an identifier associated with a service module associated with the service. The code further causes the processor to send the portion of the data packet to the service module via a distributed switch fabric such that the service module performs the service on the portion of the data packet and sends the portion of the data packet to the destination peripheral processing device via the distributed switch fabric.
