In this paper, we investigate threats against our previous work (i.e., OpenTag) in terms of confidentiality, integrity and availability. OpenTag is a tag based network slicing method for wide area coordinated in-network packet processing and traffic classification with performance isolation. OpenTag is an effective mechanism for slicing network testbeds. We also propose mitigation methods regarding...
Software-Defined Networking (SDN) increasingly attracts more researchers as well as industry attentions. Open-Flow as a major API for SDN applies <match, action> rules to every packet. However, it only supports a few actions that are all predefined. We extend this limitation of OpenFlow and propose User-Defined Actions (UDAs) for SDN. We discuss usecases of UDAs and propose an architecture to...
Software-Defined Networking (SDN) increasingly attracts more researchers as well as industry attentions. Most of current SDN packet processing approaches classify packets based on matching a set of fields on the packet against a flow table and then applying an action on the packet. We argue we can simplify this mechanism using single-field classification and reduce the overhead. We propose a tag-based...
Software Defined Networking (SDN) increasingly attracts more researchers as well as industry attentions. Most of current SDN packet processing approaches classify packets based on matching a set of fields on the packet. We propose a tag-based packet classification architecture to reduce filtering and flow management overhead.
