2000 Multimedia Computing and Networking 2001  
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.  ...

Scheduler support for video-oriented multimedia on client-side virtualization

Hwanju Kim, Jinkyu Jeong, Jaeho Hwang, Joonwon Lee, Seungryoul Maeng
2012 Proceedings of the 3rd Multimedia Systems Conference on - MMSys '12  
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.  ...

Scalable Hierarchical Scheduling for Malleable Parallel Jobs on Multiprocessor-based Systems [article]

Yangjie Cao, Hongyang Sun, Depei Qian, Weiguo Wu
2014 arXiv   pre-print
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  ...

Efficient Resource Scheduling by Exploiting Relay Cache for Cellular Networks

Chun He, Haixia Cui, Gang Feng
2015 Mathematical Problems in Engineering  
In this paper, we propose a Two-Hop Balanced Distributed Scheduling (TBS) algorithm by exploiting relay cache for non-real-time data traffic.  ...  Each relay allocates RBs for relay UEs based on the size of the relay UE's Transport Block. We also design a relay UE's ACK feedback mechanism to update the data at relay cache.  ...  Resource allocation in this kind of networks is a challenging issue to provide sufficiently high data rates for backhaul links, while maintaining fair sharing of resources with UEs.  ...
