Reflections on a clean slate 4D approach to network control and management

Albert Greenberg, Geoffrey Xie, David A. Maltz, Jibin Zhan, Jennifer Rexford, Hui Zhang

Abstract

It’s been 15 years since what we now call Software Defined Network began emerging out of a set of ideas in the networking research com- munity. This editorial note traces how the ideas in one particular paper from that time have evolved and found practical applications.

It’s Not About the Internet

Lyman Chapin

Abstract

In the policy realm what we call “Internet issues” are not actually “Internet” issues-they are well-pedigreed social, political, cultural, and economic issues, for which we clever technologists have pro- vided a rich new environment in which to grow and multiply. It follows that the people best prepared to tackle “Internet” issues may be thoughtful professionals in fields such as behavioral psychology, linguistics, sociology, education, history, ethnology, and political science-not (exclusively) “Internet experts”.

NDP: Rethinking Datacenter Networks and Stacks Two Years After

Costin Raiciu, Gianni Antichi

Abstract

NDP is a datacenter network architecture and stack that was awarded best paper at Sigcomm 2017; it is also one of the first works that explicitly aims at providing both low latency and high through- put simultaneously. We describe the progress of the field since the publication of this article.

Recalling the Early Days (First Decade) of SIGCOMM and Thoughts on Future Research Directions

Wesley Chu

Abstract

ACM SIGCOMM has reached its fiftieth birthday. The field is still remarkably strong, expanding into new disciplines as well as new application areas. Since I was an early SIGCOMM chair (1973-1977), I have been asked to recall the early days and discuss possible future directions.

Retrospective on “Fragmentation Considered Harmful”

Jeffrey C. Mogul, Christopher A Kantarjiev

Abstract

We look back at our 1987 paper, “Fragmentation Considered Harmful,” to explain why we wrote it, how the prevalence of fragmentation was reduced by approaches such as Path MTU Discovery, and how fragmentation-related issues still lurk in today’s Internet. Our paper listed several reasons why we thought fragmentation was harmful; some were more true in 1987 than they are today, and after our paper was published, the community realized that fragmentation (and the mechanisms used to mitigate it) exposed harms we did not anticipate in our paper.

Retrospective on “Measured Capacity of an Ethernet: Myths and Reality”

Jeffrey C. Mogul, Christopher A Kantarjiev

Abstract

The original Ethernet design used CSMA/CD on a broadcast cable. Even after it became commercially popular, many people expressed concerns that Ethernet could not efficiently use the full channel bandwidth. In our 1988 paper, “Measured Capacity of an Ethernet: Myths and Reality,” we reported on experiments we ran showing that, even under relatively heavy loads, Ethernet typically still performed well. We describe the context in which we ran those experiments, and some subsequent research conducted by others.
