81 results about "Multilevel queue" patented technology

Multi-level queueing, used at least since the late 1950s/early 1960s, is a queue with a predefined number of levels. Unlike the multilevel feedback queue, items get assigned to a particular level at insert (using some predefined algorithm), and thus cannot be moved to another level. Items get removed from the queue by removing all items from a level, and then moving to the next. If an item is added to a level above, the "fetching" restarts from there. Each level of the queue is free to use its own scheduling, thus adding greater flexibility than merely having multiple levels in a queue.

Traffic and load aware dynamic queue management

Some embodiments provide a queue management system that efficiently and dynamically manages multiple queues that process traffic to and from multiple virtual machines (VMs) executing on a host. This system manages the queues by (1) breaking up the queues into different priority pools with the higher priority pools reserved for particular types of traffic or VM (e.g., traffic for VMs that need low latency), (2) dynamically adjusting the number of queues in each pool (i.e., dynamically adjusting the size of the pools), (3) dynamically reassigning a VM to a new queue based on one or more optimization criteria (e.g., criteria relating to the underutilization or overutilization of the queue).

Methods and systems for managing network traffic by multiple constraints

Methods and systems for managing network traffic by multiple constraints are provided. A received network packet is assigned to multiple queues where each queue is associated with a different constraint. A network packet traverses the queues once it satisfies the constraint associated with that queue. Once the network packet has traversed all its assigned queues the network packet is forwarded to its destination. Also, network activity, associated with higher priority applications which are not managed, is detected. When such activity is detected, additional constraints are added to the network packet as it traverses its assigned queues.
