Abstract: A packet processing method for a virtual switch is carried out in a virtual switch under the SDN architecture. The method presets a signature pre-computation table including plural destination addresses and signatures corresponding to the destination addresses. With the installation of the signature pre-computation table, the destination addresses fall into packets of the signature pre-computation table without requiring computing the signature of the packet. The method simply obtains the corresponding signature according to the destination address of the packet destination address, and thus saves the time required for processing a packet and improves the throughput of the virtual switch.

Abstract: A cassette for housing and protecting splices of optical fibers, comprising a substrate and a lid, is provided. The substrate has a substrate body comprising a splice area for allowing the splices to be located thereon. A platform protruding from the substrate body has V-grooves on a top-end surface for guiding the optical fibers. The lid comprises a lid body comprising a platform-facing area for pressing towards the top-end surface when the substrate and the lid are integrated to form an assembled cassette. Multiple legs protruding from the lid body other than the platform-facing area are arranged such that a channel for allowing the optical fibers to pass through is formed between two of the legs. As a result, the channel overlies and covers the splice area to provide physical protection to the splices. The cassette is simple in structure while providing sufficient protection to the splices.

K. of at least 1.5 T. Anisotropic magnetic materials are produced by pretreating the intermetallic compound, which contains carbon, by powder sintering or oriented hot shaping, followed by nitriding and/or carbiding.
