In computer science, a priority queue is an abstract data type which is like a regular queue or stack data structure, but where additionally each element has a "priority" associated with it. In a priority queue, an element with high priority is served before an element with low priority. In some implementations, if two elements have the same priority, they are served according to the order in which they were enqueued, while in other implementations, ordering of elements with the same priority is undefined.

Optimal power saving scheduler for 802.11e APSD
A new system and method is described, utilizing a scheduler based on a transmission power consumption calculation and prioritizing algorithm. The system utilizes the (APSD) protocol specified in the 802.11e draft for saving power in wireless local area networks. The system comprises an access point having a priority queue, one or more stations, an APSD frame comprising an association ID for identifying one of the stations and a scheduled wake-up time for the identified station. An algorithm is employed for calculating the total transmission power consumption of downlink data for the stations. The AP originates and transmits to the one or more stations the APSD frame of the scheduled activation delay time. The current data to be transmitted to each station is accessed by the algorithm to determine the total transmission power consumption to each station. A priority queue in the AP is ordered from the lowest to the highest receiving power consumption, assigning the highest priority to the lowest power consumption transmission to minimize total power consumption to the PS stations in the AP queue.

Inter-network relay system and method
An inter-network relay unit is provided that is capable of simultaneously achieving guaranteed minimum bandwidth and priority control (including relay priority, discard priority, delay priority, etc.). A rate controller outputs relatively high priority packets from priority queues as guaranteed traffic based on guaranteed bandwidth for each link. Relatively low priority packets left in the priority queues are marked for preferential discard and output as best-effort traffic by an aging timer. When an output port is congested, an output queue portion discards only the marked packets. Thus, traffic having a plurality of relay priorities can use the guaranteed minimum bandwidth effectively and the guaranteed minimum bandwidth can be secured, irrespective of change in traffic volume for each relay priority level.

Multi-channel power line exchange protocol
InactiveUS7310670B1Easy to usePreserve bandwidthError prevention/detection by using return channelDigital data processing detailsStream dataExchange protocol
A scalable networking protocol that allows multiple nodes to communicate via a multi-channel network medium is described. The networking protocol allows any node on the network to assign itself as the active network server. The active network server polls client nodes based on a lineup card. The lineup card includes a high priority queue for low-latency devices, and a low priority queue for devices that can tolerate higher latencies. Network information is sent on the channels as fragments. The protocol provides bad-channel detection and retransmission of fragments in a fragment-by-fragment basis. Support for streaming data or asynchronous data is provided by allocating time slots on the network and allowing two intelligent nodes to talk directly to each other during count-limited token sessions, as arbitrated by the active network server. The network node serving as the active network server can be changed on a dynamic basis, and is typically determined by the first node initiating a transmit request on a sleeping network. Client nodes are addressed by dynamic-polling using an address isolation scheme.

InactiveUS20040092278A1Network traffic/resource managementNetwork topologiesStreaming dataLower priority
A method and system for servicing data traffic in wireless local area networks (such as IEEE 802.11 networks) in multiple queues having different levels of priority. These queues include at least a low priority queue for 'best effort' traffic, a medium priority queue for streaming data such as video pictures, and a high priority queue for voice traffic, and are serviced in order of decreasing priority. To prevent the 'best effort' traffic in the low priority queue from being 'starved', a bit is set to indicate when such a condition is likely to occur, and the low priority queue is served first when that bit has been set. Alternatively, low and medium priority traffic is handled on a weighted round-robin basis, and high priority traffic is given strict priority over both. Transmit and receive queues are handled on a rotating priority basis.

Queues are scheduled for outputting data using a hierarchical tree. Each level of the hierarchical tree includes multiple entries for storing status information associated with the queues. For example, a given entry of the tree stores multi-parameter status information associated with a corresponding queue to be serviced. To determine which of the queues is next in line for servicing, a logic circuit compares the multi-parameter status information stored in two or more entries of the tree. The next scheduled queue or highest priority queue in the tree is then serviced by outputting at least some of its data.

The disk scheduling algorithms try to service a request with lower priority and strict deadline only if serving this request is not going to violate the deadline constraints of a higher priority request. One of the algorithms uses a single queue to hold all the requests regardless of their priority. The single queue is reorganized after the arrival of a new request according to the order requests would be serviced. A second algorithm uses multiple queues. Each queue holds only requests with the same priority, and the requests in each priority queue are sorted according to their deadlines. The decision of servicing a request is made at scheduling time.
