Traffic is the technical term identifying phenomenon related to the control and transport of information within communication networks. Most research geared towards protocol development, network analysis, algorithm enhancement involves traffic generation. A traffic model emulates the user's demand for resources, characterizes the network resources for processing those demands and enables the provision of a fair estimate of the system performance based on the output generated either by a simulation or by means of analytical methods. The advent of new services has a great impact on existing network protocols used to transmit information between users. The performance analysis of a network protocol may have a severe impact if the underlying traffic model is not appropriate. A comprehensive survey of traffic models depicts that very little work has been done to develop adequate traffic models describing a particular user defined service or associated with a specific protocol. This thesis uses simulation as a tool to analyze and propose a traffic model (denoted as traffic generator hence forth) based on parameter selection of probability distributions. The study involves identifying and selecting appropriate parameters in probability distributions to characterize different user defined services (mainly packetized voice, data, and video) and propose a traffic generator based on the parameters selected.

Many existing encrypted Internet protocols leak information through packet sizes and timing. Though seemingly innocuous, prior work has shown that such leakage can be used to recover part or all of the plaintext being encrypted. The prevalence of encrypted protocols as the underpinning of such critical services as e-commerce, remote login, and anonymity networks and the increasing feasibility of attacks on these services represent a considerable risk to communications security. Existing mechanisms for preventing traffic analysis focus on re-routing and padding. These prevention techniques have considerable resource and overhead requirements. Furthermore, padding is easily detectable and, in some cases, can introduce its own vulnerabilities. To address these shortcomings, we propose embedding real traffic in synthetically generated encrypted cover traffic. Novel to our approach is our use of realistic network protocol behavior models to generate cover traffic. The observable traffic we generate also has the benefit of being indistinguishable from other real encrypted traffic further thwarting an adversary's ability to target attacks. In this dissertation, we introduce the design of a proxy system called TrafficMimic that implements realistic cover traffic tunneling and can be used alone or integrated with the Tor anonymity system. We describe the cover traffic generation process including the subtleties of implementing a secure traffic generator. We show that TrafficMimic cover traffic can fool a complex protocol classification attack with 91% of the accuracy of real traffic. TrafficMimic cover traffic is also not detected by a binary classification attack specifically designed to detect TrafficMimic. We evaluate the performance of tunneling with independent cover traffic models and find that they are comparable, and, in some cases, more efficient than generic constant-rate defenses. We then use simulation and analytic modeling to understand the performance of cover traffic tunneling more deeply. We find that we can take measurements from real or simulated traffic with no tunneling and use them to estimate parameters for an accurate analytic model of the performance impact of cover traffic tunneling. Once validated, we use this model to better understand how delay, bandwidth, tunnel slowdown, and stability affect cover traffic tunneling. Finally, we take the insights from our simulation study and develop several biasing techniques that we can use to match the cover traffic to the real traffic while simultaneously bounding external information leakage. We study these bias methods using simulation and evaluate their security using a Bayesian inference attack. We find that we can safely improve performance with biasing while preventing both traffic analysis and defense detection attacks. We then apply these biasing methods to the real TrafficMimic implementation and evaluate it on the Internet. We find that biasing can provide 3-5x improvement in bandwidth for bulk transfers and 2.5-9.5x speedup for Web browsing over tunneling without biasing.

As the world turns its focus to the protection of our societies underlying infrastructures, the realization that the world runs on computer networks has taken hold. The number of new technologies and solutions to better protect and secure the networks that allow our world to operate, is rapidly growing. As these technologies and solutions emerge, there is a need to study, test and further develop them. The Internet-Scale Event and Attack Generation Environment (ISEAGE) laboratory provides a unique environment for this studying, testing and development of networking protocols, technologies, and solutions. However, the ISEAGE laboratory also has a number of its own unique needs. Among which is the need for a methodology and framework for the generation and management of simulated network traffic. Network Traffic Simulator (NTS) provides a framework and baseline for a variety of network traffic simulation tools laid out in the ISEAGE Implementation Plan. Running from a single networked machine, the NTS tool can simulate an entire network of legitimate computer traffic in a variety of protocols and circumstances. Moreover, NTS provides the ability to script network traffic into easily readable and executable network conversations. This thesis provides the requirements, design, and implementation details of Network Traffic Simulator. This traffic simulation utility provides the ISEAGE laboratory with a unique solution for the insertion and management of networked packets and conversations, as well as a framework for the development of a suite of other network traffic insertion tools.

A Testbed for Simulation-based Analysis of Forwarding Plane- Faras Mohan DewalMaster of Applied Science (Electrical and Computer Engineering)Concordia University, Montreal QC, 2016This thesis presents a testbed capable of generating scalable realistic network traffic on a standalone machine. The functionality of the proposed testbed is to model a scalable network of client and server instances and generate network traffic to perform simulation based-analysis of forwarding plane designs. The testbed enables the designer to successfully conduct experiments on the design under test using realistic traffic profiles and assess the performance for multiple use cases. The proposed testbed defines simulation models for client and server nodes. The testbed modeling has been abstracted to three different levels. First, a base node design allows us to instantiate and manage multiple instances within the node. Second, a transmission protocol is implemented to enable data transfer between client and server instances. The final stage is the Internet application modeling stage. Our experiments show that we are able to reliably generate network traffic for up to 400 client and server instances on a standalone machine.
