Flexible Network Bandwidth and Latency Provisioning in the Datacenter
"... Predictably sharing the network is critical to achiev-ing high utilization in the datacenter. Past work has fo-cussed on providing bandwidth to endpoints, but often we want to allocate resources among multi-node ser-vices. In this paper, we present Parley, which provides service-centric minimum band ..."

Controlling the Delay of Small Flows in Datacenters
"... Abstract—As datacenters grow in size, the communication between servers has emerged as a major bottleneck. Studies have shown that datacenter workloads are highly variable in sizes, comprising of a mix of mice and elephant flows which, when coupled with hard to predict arrivals, make bandwidth provi ..."

. The latency of small flows, however, is an important performance metric and existing solutions for improving this metric for traditional packet switched as well as hybrid datacenter networks continue to be inadequate. We aim at looking at the design of a datacenter network which ensures adequate bandwidth
Cicada: Predictive Guarantees for Cloud Network Bandwidth
, 2014
"... In cloud-computing systems, network-bandwidth guarantees have been shown to improve predictability of application performance and cost [1, 30]. Most previous work on cloud-bandwidth guarantees has assumed that cloud tenants know what bandwidth guarantees they want. However, applica-tion bandwidth de ..."

-efficiency) or under-provisioning (and thus poor user experience in latency-sensitive user-facing applications). We analyze traffic traces gathered over six months from an HP Cloud Services datacenter, finding that application bandwidth consumption is both time-varying and spatially inhomogeneous. This variability
Dynamic Reconfigurability Support for providing Soft QoS Guarantees in Cluster-based Multi-Tier Data-Centers over InfiniBand
"... Current cluster-based data-centers are configured as multiple tiers, each with specific functionalities and containing multiple nodes. Over-provisioning of nodes in these data-center tiers is an accepted approach to provide Quality of Service (QoS) guarantees due to the unpredictability of incoming ..."

requests. However, this approach is not cost-effective due to the wastage of resources it could potentially incur. Current high performance networks such as InfiniBand, Myrinet, Quadrics, etc., not only provide high performance in terms of latency and bandwidth, but also a number of advanced features
Flexible Traffic Management in Broadband Access Networks using Software Defined Networking
"... Abstract-Over the years, the demand for high bandwidth services, such as live and on-demand video streaming, steadily increased. The adequate provisioning of such services is challenging and requires complex network management mechanisms to be implemented by Internet service providers (ISPs). In cu ..."

AREN: a popularity aware replication scheme for cloud storage
"... Abstract—Delivering on-demand web content to end-users in order to carry out strict QoS metrics is not a trivial task for globally distributed network providers. This task becomes still harder when content popularity varies over the time and the SLA definitions have to include both transfer rate and ..."

Current worldwide content delivery approaches and datacenter infrastructures rely on cumbersome replication schemes that are agnostic to edge-network resources, and damage content provision. In this work we present AREN, an novel replication scheme for cloud storage on edge networks. AREN
