Towards IP geolocation using delay and topology measurements
TLDR
We present Topology-based Geolocation (TBG), a novel approach to estimating the geographic location of arbitrary Internet hosts by leveraging network topology, along with measurements of network delay, to constrain host position. Expand

SDX: a software defined internet exchange
TLDR
We propose a Software Defined IXP (an "SDX") that allows networks to create and run their own packet-processing rules that match on multiple header fields and perform a variety of actions. Expand
