摘要： In one embodiment, packet memory and resource memory of a memory are independently managed, with regions of packet memory being freed of packets and temporarily made available to resource memory. In one embodiment, packet memory regions are dynamically made available to resource memory so that in-service system upgrade (ISSU) of a packet switching device can be performed without having to statically allocate (as per prior systems) twice the memory space required by resource memory during normal packet processing operations. One embodiment dynamically collects fragments of packet memory stored in packet memory to form a contiguous region of memory that can be used by resource memory in a memory system that is shared between many clients in a routing complex. One embodiment assigns a contiguous region no longer used by packet memory to resource memory, and from resource memory to packet memory, dynamically without packet loss or pause.

摘要： Method and apparatus for transporting a slurry along a pipeline having a number of downstream delivery points along its length and a plant at each delivery point for burning or otherwise using a part of the solids, such as coal, obtained from the slurry. In the practice of the method, the pipeline is filled with a carrier fluid, such as water, and batches of slurry are introduced between batches of the carrier fluid for movement along the pipeline. Each batch of slurry is separated from the batches of carrier fluid by a cap and a tail, the cap and tail being formed from a liquid suspension of fine solids. At each downstream delivery point, each batch of slurry and its cap and tail are directed out of the pipeline into a holding tank. A portion of the contents of the holding tank is removed from the holding tank and dewatered to produce a large mesh solids cake and a centrate defined as a liquid suspension of fines. The remainder of the contents of the holding tank and a cap and tail formed from the centrate is then directed into the pipeline downstream of the delivery point between the batches of carrier fluid for transit to the next delivery point along the pipeline. The foregoing steps are repeated at each successive downstream delivery point along the pipeline. At each delivery point, the cake formed by dewatering is burned or otherwise used at a plant at the delivery point. At the last delivery point, the remaining slurry is dewatered and used. the invention eliminates the need for grinding solids at each downstream delivery point to form the caps and tails material needed to isolate the batches of slurry from the carrier fluid sent on to the next delivery point.

摘要： In one embodiment, rule-based virtual address translation is performed for accessing data (e.g., reading and/or writing data) typically stored in different manners and/or locations among one or more memories, such as, but not limited to, in packet switching devices. A virtual address is matched against a set of predetermined rules to identify one or more storing description parameters. These storing description parameters determine in which particular memory unit(s) and/or how the data is stored. Thus, different portions of a data structure (e.g., table) can be stored in different memories and/or using different storage techniques. The virtual address is converted to a lookup address based on the identified storing description parameter(s). One or more read or write operations in one or more particular memory units is performed based on the lookup address said converted from the virtual address.

摘要： A service is applied in a packet switching device to both directions of a flow of packets through the packet switching device, with the application of this Layer-4 to layer-7 service to one direction requiring state information shared from the application of the service to packets traversing in the other direction. The service (e.g. firewall, network address translation) can be applied by different processing complexes which do not share memory; thus, state information is communicated between the processing complexes. When the service is applied by a single processing complex, packets can be directed explicitly to the single processing complex. The inline application of services in a packet switching system typically eliminates the need to change a packet's path through the packet switching system to that through a dedicated application server, and may eliminate the need for a dedicated services card or blade server.

摘要： A method and a network device for sharing bandwidth among a group of classes of traffic for an interface are provided. Bandwidth may be allocated to at least one traffic class of a first priority for the interface. At least some unused bandwidth of the at least one traffic class may be allocated to at least one other traffic class of a second priority for the interface. In some implementations, weighted constituents may be allocated unused interface bandwidth based on an assigned weight of each of the weighted constituents of the interface.
