Deriving Traffic Demands for Operational IP networks: Methodology and Experience
- IEEE/ACM TRANSACTIONS ON NETWORKING
, 2001
"... Engineering a large IP backbone network without an accurate, network-wide view of the traffic demands is challenging. Shifts in user behavior, changes in routing policies, and failures of network elements can result in significant (and sudden) fluctuations in load. In this paper, we present a model ..."

A methodology for estimating interdomain web traffic demand
- In IMC ’04: Proceedings of the 4th ACM SIGCOMM conference on Internet measurement
, 2004
"... This paper introduces a methodology for estimating interdomain Web traffic flows between all clients worldwide and the servers belonging to over one thousand content providers. The idea is to use the server logs from a large Content Delivery Network (CDN) to identify client downloads of content prov ..."

download are estimated separately by examining Web accesses in packet traces collected at several universities. The methodology produces a (time-varying) interdomain HTTP traffic demand matrix pairing several hundred thousand blocks of client IP addresses with over ten thousand individual Web servers. When
Equilibrium Assignment Model with Uncertainties in Traffic Demands
, 2013
"... Abstract: In this study, we present an equilibrium traffic assignment model considering uncertainties in traffic demands. The link and route travel time distributions are derived based on the assumption that OD traffic demand follows a log-normal distribution. We postulate that travelers can acquir ..."

On the Convergence of Statistical Techniques for Inferring Network Traffic Demands
, 2003
"... Accurate knowledge of traffic demands in a communication network enables or enhances a variety of traffic engineering and network management tasks of paramount importance for operational networks. Directly measuring a complete set of these demands is prohibitively expensive because of the huge amoun ..."

G.: Managing Traffic Demand Uncertainty in Replica Server Placement with Robust Optimization
, 2006
"... Abstract. The replica server placement problem determines the optimal location where replicated servers should be placed in content distribution networks, in order to optimize network performance. The estimated traffic demand is fundamental input to this problem and its accuracy is essential for th ..."

Making Intra-Domain Routing Robust to Changing and Uncertain Traffic Demands: Understanding Fundamental Tradeoffs
- SIGCOMM'03

"... Intra-domain traffic engineering can significantly enhance the performance of large IP backbone networks. Two important components of traffic engineering are understanding the traffic demands and configuring the routing protocols. These two components are inter-linked, as it is widely believed tha ..."

Adapting Publish-Subscribe Routing to Traffic Demands
"... Most of currently available content-based publish-subscribe systems that were designed to operate in large scale, wired scenarios, build their routing infrastructure as a set of brokers connected in an acyclic network. The topology of such network is critical for the performance of the system. Depen ..."

. Depending on the traffic profile, the same topology may provide good performance or be very inefficient. Starting from this consideration, in this paper we first analyze this issue in detail, then we describe a distributed algorithm to address it, by adapting the topology of a content-based publish
Scaling Microblogging Services with Divergent Traffic Demands
"... Abstract. Today’s microblogging services such as Twitter have long outgrown their initial designs as SMS-based social networks. Instead, a massive and steadily-growing user population of more than 100 million is using Twitter for everything from capturing the mood of the country to detecting earthqu ..."

It is unsurprising that the traditional centralized client-server architecture has not scaled with user demands, leading to server overload and significant impairment of availability. In this paper, we argue that the divergence in usage models of microblogging
