Abstract- Quantifying the latency sensitivity of potential customers/players is critical for Internet-based game providers when planning the network placement of their game servers. In early 2001 we placed two Quake 3 servers at different locations on the Internet, and instrumented them to gather

of cloud platforms for running latency-sensitive multimedia applications. Since multiple virtual machines running disparate applications from independent users may share a physical server, our study focuses on whether dynamically varying background load from such applications can interfere

Abstract—Cloud computing is great for scaling applications but the latency in a guest VM can be unpredictable due to resource contention between neighbors. For telephony applica-tions, which are latency-sensitive, we propose a system to monitor telephony server latencies and adapt the server load

energy consumption and maintaining satisfying QoS performance for these latency-sensitive applications. The proposed routing mechanism applies stochastic service model to calculate the latency-guarantee for any given network links. Based on such a quantitative latencyguarantee, we further propose a

Abstract-The delivery of latency sensitive packets is a crucial issue in real time applications of communication networks. Such packets often have a firm deadline and a packet becomes useless if it arrives after its deadline. The deadline, however, applies only to the packet's journey through

To support latency sensitive traffic such as voice, network providers can either use service differentiation to prioritize such traffic or provision their network with enough bandwidth so that all traffic meets the most stringent delay requirements. In the context of widearea Internet backbones

algorithms with rotation delay in concern are more promising for modern disks, not a single rotation-sensitive algorithm has ever been implemented due to lack of the knowledge of hard drive physical parameters and unawareness of disk head position. In this paper, we present a pure software based disk head

share such as CPU amount, memory size and I/O bandwidth, whereas ignore the fact that I/O latency in VM-hosted platforms is mostly related to resource provisioning rate. Even the VM is allocated with adequate resources, if they can not be provided in a timely manner, problems such as network jitter
