The goal of data center networking is to interconnect a large number of servers with low equipment cost, high performance and balanced network capacity, and robustness to link and server failures. In this paper, we present a new network interconnection structure for data centers, which leverages largely low-cost commodity Ethernet switches to support the full aggregate bandwidth of the network. Our...
A fundamental challenge in data center networking is how to efficiently interconnect a huge amount of servers. The network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Unfortunately, even when deploying the highest-end IP switches/routers, resulting topologies remain complicate...
This paper proposes a new load balancing mechanism, called PPLR (prediction packet loss rate), which is based on time series prediction. Load balancing is needed in many fields; however, current approaches have problems such as lacking of preparing for sudden spikes. In this paper, we describe how PPLR dynamically predicts loss levels over all available network paths and adjust the allocation proportion...
We proposed a new load balancing mechanism, called PPLR (predictive packet loss rate), by which flow can be divided into packets and each of the packets be transferred on an individual basis to the destination through multipath. Load balancing is needed in many fields; however, current approaches have problems such as lacking of preparing for sudden spikes. In this paper, we describe how PPLR dynamically...
Grid infrastructures have been used to solve large scale problems in science, engineering, and commerce. The management and composition of resources and services for scheduling applications, however, becomes a complex undertaking. Predicting the runtime of a task, an important component of the resource management, plays an important role in the task scheduling and the resource using in computational...
