Abstract: A content addressable memory (CAM or L3 Table) contains flow information for each active flow of packets passing through a given node of a data communications network. The CAM has associated with each entry (corresponding to each active flow) a packet counter, a byte counter, a token bucket and a contract value. Each flow is assigned one of a plurality of output queues and optionally at least one output threshold value. A token bucket algorithm is employed on each flow to determine whether packets from that flow exceed the contract value. Such packets may be dropped or optimally modified to reflect an alternate output queue and/or alternate threshold before being sent to the selected output queue for transmission from the node. In another aspect an access control list CAM (ACLCAM) contains masked flow information. The ACLCAM provides an index to internal token bucket counters and preconfigured contract values of an aggregate flow table which becomes affected by the packet statistics.

Abstract: A distributed cache management system controls individual cache objects so they are selectively updated if messages are received at another cache in an expected order and selectively invalidated if messages are received with certain error state, thus causing reference to be made to the central database. In specific embodiments of the invention, each change to an object in the central database is assigned a unique version number with an inherent ordering to serialize all changes, and the version number is used as a key to determine if messages have been lost or otherwise received at a cache out of order. In a further specific embodiment, full object state information is communicated among caches without need for verification through the central database. Thus if messages are lost or received out of order, the state can be applied to the targeted objects in the local cache assuring full synchronization.

Abstract: A method and apparatus for providing computer network access points the capability for multiple-level accounting. A gateway device located at the access point is capable of generating Internet protocol accounting start and stop requests based on various events that need to be accounted for when a user accesses a network. These events include the user account logon, the service establishments and the Point to Point protocol (PPP) connections between the gateway device and public and private domains within the network. The counter is capable of tracking the duration of sessions and connections and the byte-count associated with the specified session or connection. The gateway device communicates with an accounting server which stores the accounting requests and matches start requests with subsequent stop requests.

The non-standard power output is defined as the maximum RF power attainable such that the current drawn by the power amplifier does not exceed 400 mA. This definition permits the use of the wireless modem inside hand-held computing devices without the use of an additional battery pack extension.

Abstract: Video data predictive encoding methods using the two kinds of prediction modes, the global and local motion compensation modes, are provided, by which unnecessary MCSEL is reduced as much as possible, and the data compression efficiency is improved. In the encoder, after a code word MCBPC indicating the macroblock type and presence/absence of the DCT coefficient of each of two blocks for sending color-difference signals, a code word MCSEL indicating which motion-compensating mode, global or local, was adopted for the prediction of the current macroblock is output if the macroblock was not intraframe-encoded.

Abstract: A method and apparatus for altering code to effectively hide main memory latency using software prefetching with non-faulting loads prefetches data from main memory into local cache memory at some point prior to the time when the data is requested by the CPU during code execution. The CPU then retrieves its requested data from local cache instead of directly seeing the memory latency. The non-faulting loads allow for safety and more flexibility in executing the prefetch operation earlier because they alleviate the concern of incurring a segmentation fault, particularly when dealing with linked data structures. Accordingly, the memory access latency that the CPU sees is essentially the cache memory access latency. Since this latency is much less than the memory latency resulting from a cache miss, the overall system performance is improved.

Abstract: The present invention, generally speaking, uses multiple selectable power supply paths, a saturation detector, or combinations of the same to achieve efficient power supply processing. In one aspect of the invention, a power supply processing circuit includes a first switched converter stage and a second linear stage. Depending on the power supply desired, the first stage may be bypassed to avoid conversion losses. In another aspect of the invention, a saturation detector is used to control the first stage such that the second stage operates efficiently just short of saturation, thereby avoiding distortion.
