CISP - A Speed-of-Light Internet Service Provider

USENIX via YouTube

Overview

Explore the design and potential of cISP, a revolutionary Internet Service Provider concept that aims to transmit data at nearly the speed of light in vacuum. Delve into this 17-minute conference talk from NSDI '22, presented by researchers from various institutions, as they discuss the challenges and solutions for creating ultra-low latency wide-area networks. Learn about the integration of free-space microwave wireless connectivity with existing fiber infrastructure, and how this approach addresses practical considerations such as transmission tower availability and packet queuing. Discover the performance comparisons between cISP implementations in the United States and Europe against theoretical great-circle paths at light speed. Gain insights into the reliability of microwave networks compared to fiber networks, even in adverse weather conditions, based on experiments conducted on an algorithmic trading network. Examine the economic viability of such networks and their potential impact on various interactive network applications requiring low latency.
