DESCRIPTION:Network simulation has long been used as a tool for evaluating
  network algorithms such as congestion control. However\, configuring a si
 mulator to faithfully mimic the target network is challenging. We articula
 te the goal of ”learning the network” to recreate real-world network s
 cenarios\, i.e.\, mimicking the end-to-end behaviour of network paths base
 d on telemetry in the form of input-output packet traces. We then present 
 our proposal\, iBox\, or Internet in a Box\, to learn a model of the netwo
 rk path\, helping recreate the end-to-end behaviour of the target network 
 when presented with a new input. We discuss both networking domain knowled
 ge-based and machine learning-based approaches to iBox\, pointing out the 
 trade-offs between these\, the challenges presented by each\, and the oppo
 rtunity to meld the two. We present results from an Internet research test
 bed and from controlled experiments that show the promise of iBox.\n \nBio
 :\n\nVenkat Padmanabhan is Deputy Managing Director at Microsoft Research 
 India in Bengaluru. His research interests are broadly in networked and mo
 bile systems\, and his work over the years has led to highly-cited papers 
 and paper awards\, technology transfers within Microsoft\, and also indust
 ry impact. He received the Shanti Swarup Bhatnagar Prize in 2016\, and sev
 eral test of time paper awards from ACM SIGMOBILE\, ACM SenSys\, and ACM S
 IGMM. He was also among those recognized with the SIGCOMM Networking Syste
 ms Award 2020\, for contributions to the ns family of network simulators. 
 Venkat holds a B.Tech. from IIT Delhi (from where he received the Distingu
 ished Alumnus award in 2018) and an M.S. and a Ph.D. from UC Berkeley\, al
 l in Computer Science\, and has been elected a Fellow of the INAE\, the IE
 EE\, and the ACM. He is an adjunct professor at the Indian Institute of Sc
 ience and was previously an affiliate faculty member at the University of 
 Washington. He can be reached online at http://research.microsoft.com/~pad
