Jianchao Zhang, Shuai Gao, Xindi Hou, Fangtao Yao · 2024
CFN(Compute First Networking) is an intelligent new network with computation at its core and networking as its foundation, integrating Computational, storage, and transmission resources. Computational resources and network resources in the CFN are ubiquitous and heterogeneous. In the traditional Internet identifier system, IP addresses have limited extension, poor semantic scalability, making it challenging to incorporate information about computational and network resources into the network and hindering unified description. This paper introduces a multi-dimensional identifier system-based mechanism for computational and network resource awareness. It perceives computational network resources and employs service identifier for unified mapping. Additionally, it designs workflows for computational and network resource awareness, accomplishing tasks such as computational resource notification, request, query, update, as well as network resource detection, collection, and feedback. This facilitates functionality for service localization and computational network resource awareness. Finally, a prototype system was constructed based on the programmable data plane to experimentally evaluate the functionality and performance of the resource awareness mechanism. The results indicate that in a CFN scenario, this mechanism can support real-time perception and updates of computational network resources. In the context of distributed computing services, compared to traditional network deployments, the mechanism reduces latency by approximately 10%.
