- Multiobjective Network Design for Realistic Traffic Models
- Network topology design problems find application in several real life scenarios. However, most designs in the past either optimize for a single criterion like delay or assume simplistic traffic models like Poisson. Such assumptions make the solutions inapplicable in the practical world. This paper formulates and solves a multiobjective network...

- Towards Realistic Models of Wireless Workload
- Performance predictions from wireless networking laboratory experiments rarely seem to match what is seen once technologies are deployed. The authors believe that one of the major factors hampering researchers' ability to make more reliable forecasts is the inability to generate realistic workloads. To redress this problem, it takes a fundamentally...

- Stable Egress Route Selection for Interdomain Traffic Engineering: Model and Analysis
- This paper presents a general model of interdomain route selection to study interdomain traffic engineering. In this model, the routing of multiple destinations can be coordinated. Thus the model can capture general traffic engineering behaviors such as load balancing and link capacity constraints. The paper first identifies potential routing instability...

- Performance of TCP Over ABR With Long-Range Dependent VBR Background Traffic Over Terrestrial and Satellite ATM Networks
- Compressed video is well known to be self-similar in nature. VBR carrying long-range dependent, multiplexed MPEG-2 video sources traffic is modeled. The actual traffic for the model is generated using fast-fourier transform of the fractional gaussian noise sequence. Our model of compressed video sources bears similarity to an MPEG-2 transport...

- Risk Reduction in the Hose Model for VPN Design
- Network dimensioning is traditionally approached through the consideration of traffic matrices: the operator is assumed to know the traffic intensity for each of the Origin-Destination couples in its network. Traffic matrix measurements have therefore a central role in network planning and significant efforts have been spent, first in the telephone...

- Network Monitoring Using Traffic Dispersion Graphs (TDGs)
- Monitoring network traffic and detecting unwanted applications has become a challenging problem, since many applications obfuscate their traffic using unregistered port numbers or payload encryption. Apart from some notable exceptions, most traffic monitoring tools use two types of approaches: keeping traffic statistics such as packet sizes and inter-arrivals, flow counts,...

- Performance Analysis of IEEE 802.11 for Multi-Hop Infrastructure Networks
- Recent interest in Multi-hop Infrastructure Networks MINs has resulted in a need for an accurate model to predict the behavior of such systems. The paper considers a traffic-based network model to characterize these networks. The paper first analyzes the link delay characteristics of MINs. This is followed by a method...

- Behavior of TCP-Like Elastic Traffic at a Buffered Bottleneck Router
- A major challenge in traffic modeling and performance analysis for the Transmission Control Protocol TCP stems from the fact that the incoming traffic is not independent of the congestion level in the network. This paper investigates a queueing model where the traffic essentially shows ON/OFF characteristics, i.e. the number of...

- Modeling Internet Backbone Traffic at the Flow Level
- Modeling the Internet traffic is an important issue. It is unlikely that one will be able to understand the traffic characteristics, predict network performance (e.g., for QoS guarantees or Service Level Agreement definition), or design dimensioning tools without analytical models. The successful evolution of the Internet is tightly coupled to...
