With the rapid increase in the use of mobile devices in people's daily lives, mobile data traffic
is exploding in recent years. In the edge computing environment where edge servers are …

Increased complexity and scale of virtualized distributed systems has resulted in the
manifestation of emergent phenomena substantially affecting overall system performance …

This paper presents URSA, a hybrid block store that provides virtual disks for various
applications to run efficiently on cloud VMs. Trace analysis shows that the I/O patterns …

Optical data center networks (DCNs) are becoming increasingly attractive due to their
technological strengths compared to traditional electrical networks. However, prior optical …

In this paper, we present an approach to construct a built-in block-based hierarchical index
structures, like R-tree, to organize data sets in one, two, or higher dimensional space and …

Today's cloud is shared among multiple tenants running different applications, and a
desirable multi-tenant datacenter network infrastructure should provide bandwidth …

Large-scale data stores are an increasingly important component of cloud datacenter
services. However, cloud storage system usually experiences data loss, hindering data …

Task-aware flow schedulers collect task information across the data center to optimize task-
level performance. However, the majority of the tasks, which generate short flows and are …

DM-cache is a component of the device mapper of Linux kernel, which has been widely
used to map SSDs and HDDs onto higher-level virtual block devices that take fast SSDs as a …

In-memory key-value store (IMKVS) has gained great popularity in data centers. However,
big data brings great challenges in performance and power consumption because of the …
