This paper reviews recent advances in high speed short reach optical interconnects for Datacom links from the perspective of Ethernet applications, fiber development and system experiments based on the multimode-VCSEL paradigm.
Adoption of Cloud Computing is on the rise[1] and many datacenter operators adhere to strict energy efficiency guidelines[2]. In this paper a novel approach to scheduling in a Cloud Computing context is proposed. The algorithm Maxmin Fast Track (MXFT) revises the Max-min algorithm to better support smaller tasks with stricter Service Level Agreements (SLAs), which makes it more relevant to Cloud Computing...
The advent of software defined networking enables flexible, reliable and feature-rich control planes for data center networks. However, the tight coupling of centralized control and complete visibility leads to a wide range of issues among which scalability has risen to prominence due to the excessive workload on the central controller. By analyzing the traffic patterns from a couple of production...
Resource isolation of the computation and storage in the cloud is relatively mature, but the network resource is still shared among tenants leading to variable and unpredictable network performance when bandwidth guarantees are not enforced. Currently most of the bandwidth guarantee approaches are based on the idea of single-path reservation without fully exploiting the multipath resource, which leads...
Recent cloud datacenter network usually has multiple transmission paths for any pair of servers to increase the aggregate bandwidth and to improve the robustness of failure recovery. Therefore, Multipath TCP (MPTCP) is becoming one of the most important transport protocols exploring the multipath resource to improve the performance of cloud network. It is obvious that MPTCP could significantly increase...
Cloud computing has emerged as a new computing paradigm and its economics has opened up a new research area. Though progress has been made toward address competitions among Cloud service providers (CSPs) or among network service providers (NSPs), few studies have focused on the relationship between CSPs and NSPs. In this paper, we investigate this problem and present a new economic model to characterize...
