ex uno pluria: The Service-Infrastructure Cycle, Ossification, and the Fragmentation of the Internet

TL;DR

The paper discusses how the Internet's evolution is driven by a Service-Infrastructure Cycle, its ossification, and the potential emergence of a fragmented ManyNets world that could renew network evolution.

Contribution

It introduces the concept of the Service-Infrastructure Cycle as fundamental to networking evolution and analyzes how ossification may lead to network fragmentation and a shift towards multiple interconnected networks.

Findings

Internet has evolved through iterative Service-Infrastructure Cycles.

Ossification of the Internet hinders adaptation to new demands.

Fragmentation into ManyNets may revitalize network evolution.

Abstract

In this article I will first argue that a Service-Infrastructure Cycle is fundamental to networking evolution. Networks are built to accommodate certain services at an expected scale. New applications and/or a significant increase in scale require a rethinking of network mechanisms which results in new deployments. Four decades-worth of iterations of this process have yielded the Internet as we know it today, a common and shared global networking infrastructure that delivers almost all services. I will further argue, using brief historical case studies, that success of network mechanism deployments often hinges on whether or not mechanism evolution follows the iterations of this Cycle. Many have observed that this network, the Internet, has become ossified and unable to change in response to new demands. In other words, after decades of operation, the Service-Infrastructure Cycle has become stuck. However, novel service requirements and scale increases continue to exert significant pressure on this ossified infrastructure. The result, I will conjecture, will be a fragmentation, the beginnings of which are evident today, that will ultimately fundamentally change the character of the network infrastructure. By ushering in a ManyNets world, this fragmentation will lubricate the Service-Infrastructure Cycle so that it can continue to govern the evolution of networking. I conclude this article with a brief discussion of the possible implications of this emerging ManyNets world on networking research.
