Abstract:

[Objective] The implementation mechanism of the programmable service routing strategy for the computing power network is analyzed and designed, which enables the network to call computing resources flexibly, efficiently, and on-demand in real-time. [Methods] Combined with the programmable service concept of the computing power network, three implementation mechanisms of routing strategies are designed, including centralized, distributed, and combination of the centralized and distributed coordination. This article describes decision-making, traffic forwarding, and other service processes of these implementation mechanisms, as well as technical features and application scenarios. [Results] The programmable service routing strategy for computing power networks can be deployed based on the characteristics of business scenarios and network conditions, and different implementation mechanisms can be selected as needed. [Conclusions]The research on the programmable service routing strategy of the computing power network will enable the integrated scheduling of the computing network, and realize access to computing power anytime and anywhere. However, it is still necessary to promote in-depth research and implementation in terms of technical standards, commercial applications, and industrial ecology.
