摘要： A hierarchical traffic policer may include a first policer configured to pass first packets when a first condition is met. The first policer also may alter selection information within the passed first packets. A second policer may be configured to pass second packets when a second condition is met. The second policer may be further configured to pass all of the passed first packets from the first policer based on the altered selection information within the passed first packets.

摘要： A network device includes an interface and packet processing logic. The interface receives a multicast packet. The packet processing logic determines identifier data corresponding to the received multicast packet and replicates the identifier data to multiple outgoing packet forward engines at a first point in a processing path. The packet processing logic further replicates the identifier data to multiple data streams at a second point in the processing path and replicates the identifier data to multiple logical interfaces in the same stream at a third point in the processing path.

摘要： Ordering logic ensures that data items being processed by a number of parallel processing units are unloaded from the processing units in the original per-flow order that the data items were loaded into the parallel processing units. The ordering logic includes a pointer memory, a tail vector, and a head vector. Through these three elements, the ordering logic keeps track of a number of “virtual queues” corresponding to the data flows. A round robin arbiter unloads data items from the processing units only when a data item is at the head of its virtual queue.

摘要： A network device constructs a notification corresponding to a received multicast data unit, where the notification includes administrative data associated with the multicast data unit that does not include a payload of the multicast data unit. The network device replicates the notification at least three different processing elements at different locations in a processing path of the network device to produce multiple replicated data items and produces a copy of the multicast data unit for each of replicated notifications. The network device forwards each copy of the multicast data unit towards a multicast destination.

摘要： A scaleable network based computer system having a distributed texture memory architecture. A network residing within the computer system is used to transmit packets between a host processor and a number of subsystems. Three basic types of subsystems are coupled to the network: a geometry subsystem is used to process primitives; a rasterization subsystem is used to render pixels; and a display subsystem is used to drive a computer monitor. Any number and combination of these three types of subsystems can be coupled to one or more network chips to implement a wide variety of configurations. One or more memory chips can be coupled to any of the rasterization subsystems. These memory chips are used to store texture data. A rasterization subsystem can access texture data from its associated memory chips or can request texture data residing within any of the other memory chips. The request is sent over the internal network; the requested texture data is packetized and sent over the internal network to the requesting rasterization subsystem. Because texture data is distributed across the internal network and is accessible to any and all rasterization subsystems, there is no need to store duplicate copies. Furthermore, the computer system is readily scaleable simply by adding the appropriate geometry, rasterization, or display subsystem. Likewise, texture memory is readily scalable simply by adding more memory chips.
