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： 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： A graphics geometry cache. The basic idea of one embodiment in accordance with the present invention is to utilize a graphics geometry cache together with a graphics pipeline. The graphics geometry cache is a relatively small cache (e.g., 128 entries) used for storing and maintaining vertex data. Specifically, the results of computations performed on vertices by the graphics pipeline (e.g., transformed vertices and attributes such as color) are cached within the graphics geometry cache. Furthermore, the cached entries are tagged by their corresponding vertex coordinates. Subsequently, when a particular vertex is specified for the graphics pipeline, a tag compare is executed through a hashing function to determine whether the graphics geometry data for that particular vertex is stored within the graphics geometry cache. If a hit occurs during the tag compare, a copy of the graphics geometry data is retrieved from the graphics geometry cache rather than having to recompute the graphics geometry data for that particular vertex. Therefore, one of the advantages of the graphics geometry cache of the present embodiment is that it saves computational resources.
摘要翻译：图形几何缓存。根据本发明的一个实施例的基本思想是将图形几何高速缓存与图形流水线一起使用。图形几何高速缓存是用于存储和维护顶点数据的相对较小的缓存（例如，128个条目）。具体地说，图形流水线对顶点执行的计算结果（例如，变换的顶点和诸如颜色的属性）被缓存在图形几何高速缓存内。此外，缓存的条目由其对应的顶点坐标标记。随后，当为图形管线指定特定顶点时，通过散列函数执行标签比较，以确定该特定顶点的图形几何数据是否存储在图形几何高速缓存内。如果在标签比较期间发生命中，则从图形几何缓存中检索图形几何数据的副本，而不必重新计算该特定顶点的图形几何数据。因此，本实施例的图形几何高速缓存的优点之一是节省了计算资源。

摘要： A content player transmits a screen image to a display. The screen image includes an active region, which may be a portion that may be manipulated. The player determines active region information for the active region and transmits such to a portable device. The portable device receives the active region information as well as information regarding any inactive regions, which may be portions that may not be manipulated. The portable device utilizes the information to present a simulated version of the screen image on a touch screen. The portable device may then receive manipulation information via the touch screen and transmit such to the player. In response, the player may generate and present an updated version of the screen image, determine updated information, and transmit such to the portable device. The portable device may utilize the updated information to present a simulated updated version of the screen image.
