Rate-matching packet scheduler for real-rate applications
2000
Multimedia Computing and Networking 2001
Preserved Fulltext
A packet scheduler is an operating system component that controls the allocation of network interface bandwidth to outgoing network flows. ...
Next generation packet schedulers must not only ensure separation among flows and meet real-time performance constraints, they must also support dynamic fine-grain reallocation of bandwidth for flows with ...
Finally, the RAMP scheduler uses a feedback-driven control system to manage network interface resources. ...

This paper presents a new scheduling scheme for the hypervisor to transparently identify if the workload handles multimedia and to provide proper scheduling supports. ...
An implementation of our scheme has shown that the virtual machine hosting a video-oriented application receives propoer CPU scheduling even when other virtual machines host CPU intensive workloads. ...
A feedback-driven mechanism requires a quality estimation method in order to apply positive or negative feedbacks for adjusting CPU allocation. For example, Steere et al. ...

We decouple the design goals of resource proportionality from resource provisioning rate, and adopt divide-and-conquer strategy to defeat network jitter for VMs: (1) in VMM CPU scheduling, we differentiate ...
Even the VM is allocated with adequate resources, if they can not be provided in a timely manner, problems such as network jitter will be very serious and significantly affect the performance of cloud ...
Specifically, we propose a double runqueue design for each physical CPU, which can provide real-time scheduling and meanwhile maintain CPU time proportional share. ...

We propose a hierarchical scheduling algorithm, named AC-DS, that consists of a feedback-driven adaptive scheduler, a desire aggregation scheme and an efficient resource allocation policy. ...
The results verify the scalability of AC-DS and demonstrate that AC-DS outperforms other strategies for a wide range of parallel workloads. ...
For this purpose, we apply a feedback-driven scheduler, called A-Control (or AC for short) [9, 17] , which predicts the processor requirements or desires for each job periodically after a pre-defined ...
