摘要： Disclosed is a hierarchy of individual schedulers with multiple scheduling lanes for scheduling items, such as, but not limited to packets or indications thereof, such that different classes of priority items can be propagated through the hierarchy of schedulers accordingly. A pipeline scheduler typically includes a root scheduler and one or more layers of schedulers with each of these layers including at least one scheduler. Each scheduler is configured to maintain items of different scheduling categories received from each of the particular scheduler's immediate children schedulers within the pipeline scheduler if any and from each immediate external source coupled to the particular scheduler if any, and to schedule the sending of the items of the different scheduling categories currently maintained to its parent schedule or external scheduler client. The items may correspond to packets, indications of packets, or any other entity.

摘要： In one embodiment, the invention provides a method for configuring a wireless device, so as to enable the wireless device to join a secured wireless network, by broadcasting a series of broadcast packets encoding a network configuration parameter (e.g., a shared secret key) from a computer coupled to a wireless access point to the wireless device. The information representing the network configuration parameter is encoded, not within the payload portion of the packet, but within the length of each broadcast packet in the series of broadcast packets. Accordingly, a wireless device that has not yet been configured to receive packets from the wireless access point can observe the information encoded in the length of each broadcast packet, and thereby decode the network configuration parameter and join the network.

摘要： Eligible entries are scheduled using an approximated finish delay identified for an entry based on an associated speed group. One implementation maintains schedule entries, each respectively associated with a start time and a speed group. Each speed group is associated with an approximated finish delay. An approximated earliest finishing entry from the eligible schedule entries is determined that has an earliest approximated finish time, with the approximated finish time of an entry being determined based on the entry's start time and the approximated finish delay of the associated speed group. The scheduled action corresponding to the approximated earliest finishing entry is then typically performed. The action performed may, for example, correspond to the forwarding of one or more packets, an amount of processing associated with a process or thread, or any activity associated with an item.

摘要： A hierarchy of schedules propagate minimum guaranteed scheduling rates among scheduling layers in a hierarchical schedule. The minimum guaranteed scheduling rate for a parent schedule entry is typically based on the summation of the minimum guaranteed scheduling rates of its immediate child schedule entries. This propagation of minimum rate scheduling guarantees for a class of traffic can be dynamic (e.g., based on the active traffic for this class of traffic, active services for this class of traffic), or statically configured. One embodiment also includes multiple scheduling lanes for scheduling items, such as, but not limited to packets or indications thereof, such that different categories of traffic (e.g., propagated minimum guaranteed scheduling rate, non-propagated minimum guaranteed scheduling rate, high priority, excess rate, etc.) of scheduled items can be propagated through the hierarchy of schedules accordingly without being blocked behind a lower priority or different type of traffic.

摘要： Schedules may use burst tolerance values to adjust the scheduling in a time-based schedule, such as, but not limited to, adjusting for accumulated but not used bandwidth, and/or adjusting eligibility of schedule entries. A best schedule item associated with an eligible schedule entry of a schedule is identified. Whether or not a particular schedule entry is eligible is typically determined based on the relationship of an associated timestamp with a current scheduling time, such as its timestamp being less than or equal to the current time. A burst tolerance time bound might also be used to allow certain priorities and/or types of items to be considered eligible if even its timestamp exceeds the current time by an amount, but less than or equal to the burst tolerance time bound. When a schedule entry which has been dormant becomes active, its one or more timestamps are typically initialized, which may include setting at least one of these timestamps behind current time by a wakeup burst tolerance value to guarantee its immediate eligibility for one or more consecutive scheduling iterations.

摘要： A distributed database system has multiple compute nodes each running an instance of a database management system (DBMS) program that accesses database records in a local buffer cache. Records are persistently stored in distributed flash memory on multiple storage nodes. A Sharing Data Fabric (SDF) is a middleware layer between the DBMS programs and the storage nodes and has API functions called by the DBMS programs when a requested record is not present in the local buffer cache. The SDF fetches the requested record from flash memory and loads a copy into the local buffer cache. The SDF has threads on a home storage node that locate database records using a node map. A global cache directory locks and pins records to local buffer caches for updating by a node's DBMS program. DBMS operations are grouped into transactions that are committed or aborted together as a unit.
