Service Aware Network
摘要
Abstract
With the vigorous development of new technologies and services such as artificial intelligence,big data,cloud computing,etc.,the communication paradigm between Internet applications,which plays a supporting role,has evolved from the traditional"request-get"one-stage to the complex"request-compute-get"two-stage.The new communica-tion paradigm requires the network not only to provide the data transmission channels but also to assume the role of opening up computation in the form of public services on the Internet,thus deepening the integration of computing and network and promoting the development of the digital economy.However,in the network architecture represented by the current TCP/IP architecture,there are some drawbacks in the core mechanisms,including resolution and discovery,network awareness,and route computation,which make it difficult to become a foundation for new applications oriented to the convergence of com-munication and computing.In this paper,we propose a new implementation architecture named service aware network(SAN),which systematically changes the existing design of host interconnection to provide comprehensive,open,and guar-anteed endogenous service interconnection support for new scenarios such as computing network convergence.In SAN,a semantic service identifier enables user terminals to initiate location-independent connections based on service types.Com-puting and network demand awareness provides a proactive method for the network to obtain the requirements of requests."Two-stage two-layer"routing not only realizes the routing considered two-dimensional computing and bandwidth resourc-es but also guarantees the feasibility and validity of SAN deployment under different degrees of network openness.To quickly implement the concept of SAN,the SAN architecture avoids major transformation of the existing network through incremental deployment.It realizes new mechanisms without affecting the functions of the existing network and promotes the smooth evolution of the network from host interconnection to service interconnection.Experiments show that the SAN routing mechanism reduces the upper bound of service completion time by 35.4%and 17.5%,respectively,compared with the benchmark routing algorithms,and achieves more balanced and efficient computing and network resource usage.关键词
