Eagle is a new hybrid data center scheduler that considerably improves the job completion times for short jobs. Eagle builds on the Hawk hybrid scheduler, using a centralized scheduler for long jobs and distributed schedulers for short jobs. The main innovation in Eagle is that it provides an approximate and potentially slightly outof-date summary of the centralized scheduler state to the distr...

In this paper,wepresent a scheduling algorithm that enhances the performance of the standard IEEE802.11e scheduler for the HybridCoordination FunctionControlledChannelAccessmode. Themain contribution in designing the proposed scheduler is the ability to accommodate multiple streams with different levels of Quality of Service requirements concurrently running on the same station. This is achieve...

This paper presents a new scalable buffer-management scheme for IP Differentiated Services. The scheme consists of a Differentiated Random Drop (DRD) algorithm using feedback from a virtual scheduler. DRD choses a queue to perform an early packet drop to avoid congestion according to a specific probability function. First it will be shown that DRD in conjunction with first-come firstserved sche...

We present in this paper the joint optimization of a dynamic queue scheduling scheme for the provision of Quality of Service (QoS) over Wireless Local Area Networks (WLANs). Previous works tune the size of the queue of the scheduler according to the requirements of the users either in terms of expected delay or required throughput. In this paper, we present a joint optimization of the scheduler...

The quality of service many modern communication systems depends on the delay performance underlying network. In digital subscriber line (DSL) networks, for example, crosstalk introduces competition data rate among users, which influences distribution. such a competitive environment, is largely determined by manner in resources are dynamically allocated to different users. A common approach thi...

While modern desktop workloads include a substantial multimedia component, virtually no contemporary general purpose operating system provides adequate support for multimedia applications when executed under loaded conditions. Trying to play a DVD movie or participating in a role playing game with significant graphical requirements while running demanding assignments in the background (such as ...
