Spot Transit: Cheaper Internet Transit for Elastic Traffic

Efficient Traffic Assignment for Public Transit Networks

We study the problem of computing traffic assignments for public transit networks: Given a public transit network and a demand (i.e. a list of passengers, each with associated origin, destination, and departure time), the objective is to compute the utilization of every vehicle. Efficient assignment algorithms are a core component of many urban traffic planning tools. In this work, we present a...

Traffic 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...

Two Dimensional Mixed Traffic Flow Considering the Transit Traffic

Based on the two-dimension cellular automaton traffic flow model (BML model), a mixed traffic flow model of urban traffic that considering the transit traffic is established in this paper by using theDon't block the box rules. We have investigated the influences of the transit traffic ratio, and found that, in most cases, the urban traffic flow exhibited jam phase. Moreover, focusing on the tra...

Tweak-it: BGP-based Interdomain Traffic Engineering for transit ASes

Today, engineering interdomain traffic in large transit ASes is a difficult task due the opacity of BGP and the complex interactions between the BGP decision process and IGP routing. In this paper we propose Tweak-it, a tool that, based on the steady-state view of BGP routing inside the AS and the traffic demands of the AS, computes the BGP updates to be sent to the ingress routers of a transit...
