Ermore, the presence of a lot of distinct forms of tables around the information plane complicates the southbound interface and tends to make network management extra complex. 6. Conclusions In this paper, we propose a process for adopting information type and information location to represent information in the SDN information plane, enabling the switch to handle various types of information with an unified match-action table, thereby enhancing information plane programmability. This information representation strategy enables data loading and storage to be decoupled from data matching and instruction execution. The matching field and instruction function are no longer dependent on information kind or information which means immediately after decoupling. The match-action table might be reused by network applications to manage user-defined information. The data plane not simply supports the original variety of information processing, nevertheless it also can simply help new types of information by expanding the information loading and storage module. Directions can naturallyElectronics 2021, 10,14 ofallow interoperability amongst Naftopidil Biological Activity different kinds of information by mixing the data sorts controlled by directions. Acquiring the information absolute address primarily based around the information form in packet forwarding may perhaps improve forwarding latency. We proposed an application-to-switch information location conversion interaction technique that stores the base addresses of different sorts of data beforehand. By calculating the essential data address when switch adding the table or the entry, we solved the problem that acquiring the information address could increase the forwarding latency. We built a pipeline that represents information with the data kind and data place applying Intel’s DPDK framework. The pipeline’s match-action table is independent of your matching protocol or information type. The pipeline also supports atomic guidelines for example arithmetic operations, branch comparison, packet forwarding, and entry operation. The impact of data sort (instant information, packet field, metadata, flow state, worldwide state) and information place conversion interaction on pipeline overall Pirimicarb Purity performance is investigated. The experimental findings demonstrate that the information sort utilized to process the packet has no impact on packet forwarding latency. Additionally, we transform the data place with pretty little time price (three.68 us), avoiding the loss of forwarding performance triggered by computing the data address in packet forwarding. Future work will entail implementing the proposed data representation approach on programmable hardware (which include an FPGA) and expanding the P4 language to express the match-action table compatible with multi-type information applying the information representation strategy described in this paper.Author Contributions: Conceptualization, L.J., X.C. and J.W.; methodology, L.J. and X.C.; application, L.J. and X.C.; validation, L.J.; writing–original draft preparation, L.J.; writing–review and editing, L.J., X.C. and J.W.
