Abstract

The question of whether an ideal network exists with global scalability in its full life cycle has always been a first-principles problem in the research of network systems and architectures. Thus far, it has not been possible to scientifically practice the design criteria of an ideal network in a unimorphic network system, making it difficult to adapt to known services with clear application scenarios while supporting the ever-growing future services with unexpected characteristics. Here, we theoretically prove that no unimorphic network system can simultaneously meet the scalability requirement in a full cycle in three dimensions—the service-level agreement (S), multiplexity (M), and variousness (V)—which we name as the “impossible SMV triangle” dilemma. It is only by transforming the current network development paradigm that the contradiction between global scalability and a unified network infrastructure can be resolved from the perspectives of thinking, methodology, and practice norms. In this paper, we propose a theoretical framework called the polymorphic network environment (PNE), the first principle of which is to separate or decouple application network systems from the infrastructure environment and, under the given resource conditions, use core technologies such as the elementization of network baselines, the dynamic aggregation of resources, and collaborative software and hardware arrangements to generate the capability of the “network of networks.” This makes it possible to construct an ideal network system that is designed for change and capable of symbiosis and coexistence with the generative network morpha in the spatiotemporal dimensions. An environment test for principle verification shows that the generated representative application network modalities can not only coexist without mutual influence but also independently match well-defined multimedia services or custom services under the constraints of technical and economic indicators.

多态网络环境的理论框架
理想网络在其整个生命周期内是否具有全局可扩展性,一直是网络系统和架构研究中的第一性原理问题。迄今为止,我们还无法在非形态网络系统中科学地实践理想网络的设计标准,这使得它既难以适应应用场景明确的已知服务,又难以支持未来不断增长的、具有意想不到特性的服务。在此,我们从理论上证明,任何非形态网络系统都无法同时满足服务等级协议(S)、复用性(M)和多样性(V)三个维度的全周期可扩展性要求,我们将其命名为 "不可能的 SMV 三角 "困境。只有转变当前的网络发展范式,才能从思维、方法和实践规范等方面解决全球可扩展性与统一网络基础设施之间的矛盾。本文提出了多形态网络环境(PNE)的理论框架,其首要原则是将应用网络系统与基础设施环境分离或解耦,在给定的资源条件下,利用网络基线元素化、资源动态聚合、软硬件协同编排等核心技术,生成 "网络的网络 "的能力。这就有可能构建一个理想的网络系统,该系统的设计是为了适应变化,并能在时空维度上与生成网络形态共生共存。一个用于原理验证的环境测试表明,生成的代表性应用网络模式不仅可以共存而互不影响,而且可以在技术和经济指标的限制下独立匹配定义明确的多媒体服务或定制服务。
