Modeling Congested Internet Connections

چکیده
In this paper, we introduce a continuous-time model aimed at capturing the dynamics of congested Internet connections. The model combines a system of differential equations with a sudden change in one of the state variables. Results from this model show good agreement with the well-known ns network simulator, better than the results of a previous, similar model. This is due in large part to the use of the sudden change to reflect the impact of lost data packets. We also discuss the potential use of this model in network traffic state estimation.

Two Models for the Study of Congested Internet Connections
In this paper, we introduce two deterministic models aimed at capturing the dynamics of congested Internet connections. The first model is a continuous-time model that combines a system of differential equations with a sudden change in one of the state variables. The second model is a discrete-time model with a time step that arises naturally from the system. Results from these models show good...
متن کاملAuction Models for Multi-Provider Internet Connections
Auctions are a widely used approach for determining the current market price for congested resources. However, using them for real systems, such as the Internet, the auction algorithms require modifications as soon as connections cover links from more than one Internet Service Provider. This paper presents work in progress on two new auction schemes that have been designed to overcome this prob...
متن کاملBGP session lifetime modeling in congested networks
The reliable Border Gateway Protocol (BGP) is essential for supporting high quality Internet data communication. In present Internet, due to the lack of differentiation mechanism in packet forwarding, BGP sessions are sensitive to severe network congestion. It is thus important to understand the reliability of BGP in congested networks, for the purposes of system reliability evaluation and fail...
متن کاملTraffic Congestion Measurements in Transit Ip Networks
Transit IP internetworks supporting USAF bases are highly congested during duty-hours and attempts to access to the Internet often fail. Often, during these connection failures, transit networks are in a state known as congestion collapse and connections time out when a user attempts to reach the Internet. This paper presents the results of a simple IP congestion analysis between four USAF base...
متن کاملIntrusion Detection in IOT based Networks Using Double Discriminant Analysis
Intrusion detection is one of the main challenges in wireless systems especially in Internet of things (IOT) based networks. There are various attack types such as probe, denial of service, remote to local and user to root. In addition to known attacks and malicious behaviors, there are various unknown attacks that some of them have similar behavior with respect to each other or mimic the norma...
