Construction of SFC+X orchestration evaluation environment in data center:A POC approach
According to different scenario requirements and corresponding business needs,service function chaining(SFC)can be deployed from the edge cloud to the data center,between data centers,and within the data center.However,due to the inherent heavy asset nature of data centers,the assess-ment of flexibly combined SFC+X orchestration on this basis is difficult to carry out without an eco-nomically efficient assessment environment.Using a proof of concept(POC)method for assessment allows for the realization of a model or its most critical components in actual situations,enabling the val-idation of concerns at a relatively low implementation cost.In the process of assessing SFC+X orches-tration in data centers,this paper analyzes whether the POC assessment environment can effectively evaluate the correctness of SFC+X orchestration functions and effectively measure the performance indi-cators of SFC+X orchestration,explores whether the POC assessment method can solve the problem of assessing SFC+X orchestration in data centers,and demonstrates the principle of correct transmission of SFC functions and the principle of maintaining the degradation relationship of performance indicators.Furthermore,the feasibility theorem of the POC assessment method is proposed.Based on these princi-ples and theorems,combined with the characteristics of SFC+X orchestration in data centers,the hard-ware resources required for assessment are simplified to design and implement the POC assessment envi-ronment.Through theoretical derivation and POC validation methods,it is proved that the POC assess-ment method can not only effectively evaluate the correctness of SFC+X orchestration functions but also measure the performance indicators of SFC+X orchestration.Finally,an assessment method based on the POC method is proposed to determine whether the SFC+X orchestration in the data center meets the Service Level Agreement(SLA),providing an economically efficient solution to the problem of as-sessing SFC+X orchestration in data centers.
