随着大量资源被用于干净的网络研究，了解干净的架构研究与进化研究的截然相反的范式相比是多么重要。本文通过一个生物学的隐喻来探讨“进化与白板”之争。我们认为，进化研究可以导致成本更低（更具竞争力）和更强大的设计比干净的石板建筑研究。我们还认为，互联网架构并不僵化，最近声称，但其核心协议发挥的作用“进化内核”，这意味着他们是保守的，以便复杂性和多样性可以出现在较低和较高的层次。然后，我们讨论的因素，确定部署新的架构或协议，并认为，基于“自催化集”的概念，成功的创新是那些成为协同组件在现有模块的闭环。论文最后强调了进化互联网研究的作用
As significant resources are directed towards clean-slate networking research, it is imperative to understand how clean-slate architectural research compares to the diametrically opposite paradigm of evolutionary research. This paper approaches the "evolution versus clean-slate" debate through a biological metaphor. We argue that evolutionary research can lead to less costly (more competitive) and more robust designs than clean-slate architectural research. We also argue that the Internet architecture is not ossified, as recently claimed, but that its core protocols play the role of "evolutionary kernels", meaning that they are conserved so that complexity and diversity can emerge at the lower and higher layers. We then discuss the factors that determine the deployment of new architectures or protocols, and argue, based on the notion of "auto-catalytic sets", that successful innovations are those that become synergistic components in closed loops of existing modules. The paper closes emphasizing the role of evolutionary Internet research
