Peering between Content Delivery Networks (CDNs) endeavors to ensure that each user is served by an optimal Web server in terms of network cost, even under heavy load conditions. Therefore, a dominant factor for the success of peering between CDNs is to perform load distribution to handle highly skewed loads. In this paper, our approach for dynamic load distribution adopts a request-redirection...

Load balancing is a primary consideration in Adhoc networks, due to scarcity of resources. Equitable distribution of the load reduces consumption of network resources and provides homogeneous traffic characteristics in the network, such as load per node or the time from end-to-end incurred on each path. In this paper we present an optimization of the reactive routing protocol AODV with load bal...

Unstructured peer-to-peer (P2P) networks have become a very popular architecture for content distribution in large-scale and dynamic environments. The search efficiency problem in unstructured P2P networks has not been adequately addressed so far, especially concerning search for rare objects. In this paper, we propose a proactive replication strategy to improve search efficiency for rare objec...

We propose a novel SIR epidemic model which is driven by the transmission of infection packets in networks. Specifically, infected nodes generate and deliver infection packets causing the spread of the epidemic, while recovered nodes block the delivery of infection packets, and this inhibits the epidemic spreading. The efficient routing protocol governed by a control parameter α is used in the ...

The newly described piscine reovirus (PRV) appears to be associated with the development of heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon Salmo salar L. PRV seems to be ubiquitous among fish in Norwegian salmon farms, but high viral loads and tissue distribution support a causal relationship between virus and disease. In order to improve understanding of the distributi...

We consider a cache network consisting of storage-enabled servers forming a distributed content delivery scenario. Each incoming content request, arriving uniformly at random to these servers, will be redirected to one or more responsible servers for that request. While assigning each request to its nearest available replica seems to be a reasonable solution, specifically in terms of communicat...

As the web continues to evolve, its users have gone from only consuming content to actually producing it, resulting in systems with highly dynamic, user-generated content that cannot be easily modelled with existing tools. In this paper we investigate two such systems, digg and reddit, derive a general model for them, and show how this model can be used to improve their efficiency as well as th...

A load flow and short circuit fault simulation of AC electrified railway distribution systems is presented with DIgSILENT PowerFactory software. Load flow of electrified railways distribution system with concerning multi train lines and dynamic characteristics of train load is studied for different time laps. The dynamic characteristics of train load in starting and braking conditions with diff...

Enterprises may use a service-oriented architecture (SOA) to provide a streamlined interface to their business processes. To scale up the system, each tier in a composite service usually deploys multiple servers for load distribution and fault tolerance. Such load distribution across multiple servers within the same tier can be viewed as horizontal load distribution. One limitation of this appr...
