Applications of wide-area network slicing for improving cloud platform access by OpenTag

Recently, cloud computing has been extensively used worldwide and network slicing has attracted attentions for improving the access to the cloud platform. We have recently proposed a tag based slicing mechanism for coordinated wide-area packet processing, called OpenTag. In this paper, we introduce a viable application on top of an OpenTag slice to demonstrate the usefulness and benefit of OpenTag architecture and tag-based resource slicing for high-speed packet processing. Our contributions are three-fold: (1) designing the OpenTag architecture for enabling user-oriented packet processing, (2) implementing a prototype of OpenTag system with all the components along end-to-end paths, (3) evaluating the feasibility of applications on top of OpenTag for improving the robustness of the access to cloud platforms.
