摘要： Methods and systems are provided for hardware-accelerated packet multicasting in a virtual routing system. According to one embodiment, a multicast packet is received at an ingress system of a packet-forwarding engine (PFE). The ingress system identifies flow classification indices for the multicast packet. Then, for each instance of multicasting, the ingress system sends a single copy of the multicast packet and the flow classification indices to an egress system of the PFE. The single copy of the multicast packet is buffered in a memory accessible by the egress system. The egress system prepares the multicast packet for transmission by for each flow classification index, identifying corresponding transform control instructions based on the flow classification index, reading the single copy of the multicast packet from the memory, causing the multicast packet to be transformed in accordance with the identified transform control instructions and outputting the transformed multicast packet.

摘要： A system that designs, implements, and manages client applications on mobile devices using runtime executives and an IDE. In one aspect, the runtime executive delivers consistent GUI and application behavior within and across mobile development platforms. In another aspect, the runtime executive can set up data files of an IDE-generated client application on mobile devices and then become that application itself while supporting a pay-per-download subscription service. The runtime executive delivers multimedia content in presentation format via a one-level browsing interface, enables data entries across tabbed views with minimal typing and drilidowns via a one-level data entry interface, and precisely processes scripts and commands, including calls to COM libraries. The IDE allows non-programmers to design the GUI and the scripts for mobile device applications and compile them into application data files for multiple development platforms, which are then loaded and executed by runtime executives.

摘要： Methods and systems are provided for routing traffic through a virtual router-based network switch. According to one embodiment, a method for routing packets in a router includes establishing a flow data structure, which identifies a packet flow through a virtual router in the router. When a packet is received, a comparison is performed between a subset of at least one packet header associated with the packet and a subset of the flow data structure. If the subset of the packet header matches the subset of the flow data structure, then the packet can be hardware accelerated to a network interface. Otherwise, the packet may be either dropped or forwarded to a general purpose processor for processing.

摘要： A virtual routing platform includes a line interface a plurality of virtual routing engines (VREs) to identify packets of different packet flows and perform a hierarchy of metering including at least first and second levels of metering on the packet flows. A first level of metering may be performed on packets of a first packet flow using a first metering control block (MCB). The first level of metering may be one level of metering in a hierarchy of metering levels. A second level of metering on the packets of the first packet flow and packets of a second flow using a second MCB. The second level of metering may be another level of metering in the hierarchy. A cache-lock may be placed on the appropriate MCB prior to performing the level of metering. The first and second MCBs may be data structures stored in a shared memory of the virtual routing platform. The cache-lock may be released after performing the level of metering using the MCB. The cache-lock may comprise setting a lock-bit of a cache line index in a cache tag store, which may identify a MCB in the cache memory. The virtual routing platform may be a multiprocessor system utilizing a shared memory having a first and second processors to perform levels of metering in parallel. In one embodiment, a virtual routing engine may be shared by a plurality of virtual router contexts running in a memory system of a CPU of the virtual routing engine. In this embodiment, the first packet flow may be associated with one virtual router context and the second packet flow is associated with a second virtual router context. The first and second routing contexts may be of a plurality of virtual router contexts resident in the virtual routing engine.

摘要： Non operational shock resistance is achieved by preventing separation of the read/write head from the disk. Embodiments include optimizing the normal stiction force of a lubricant topcoat by controlling the texture geometry of the landing zone and lubricant topcoat thickness, particularly the density of protrusions. Laser textured landing zones having a protrusion density above about 4,500 protrusions/mm.sup.2 can provide an optimal normal stiction force in excess of 25 gf per interface and a lateral stiction force below 10 gf per interface.
