Item Programmable Data Plane for New IP using eXpress Data Path (XDP) in Linux(IEEE Computer Society, 2022) Kataria, B.; Rohit, R.; Monis, L.; Tahiliani, M.P.; Makhijani, K.This paper demonstrates a new dimension in packet programming and processing by leveraging New IP technology since applications are sensitive to different types of network constraints. For instance, emerging industry operations, manufacturing, and autonomics are limited by the stochastic quality of services and inflexible address structures. Instead, they require efficiency and deterministic networks. In this paper, we propose a programmable data plane for New IP packet processing and show how network headers could evolve in the future. We demonstrate the implementation of New IP stack to encompass three goals: (1) address customization: applications and routers can forward packets between hosts with different address formats. (2) design an end-to-end model to meet service delivery guarantees: routers implement various in-network New IP contracts as described by the applications. (3) Rapid experimentation of the New IP components. With New IP, developers can describe packet processing functionalities without depending on the specifics of the underlying hardware. Our implementation of New IP stack uses the existing toolsets and capabilities of the Linux platform, such as eXpress Data Path (XDP) and Traffic Control (TC) subsystem. It consists of an end-to-end solution with a new network stack on the host side and a corresponding packet processing and forwarding engine on the network. It is validated using Network Stack Tester (NeST), a lightweight tool built on Linux network namespaces. © 2022 IEEE.Item TinTin: Tiny In-Network Transport for High Precision INdustrial Communication(IEEE Computer Society, 2022) Makhijani, K.; Kataria, B.; Shashank, D.; Devkota, D.; Tahiliani, M.P.The design of a transport protocol for high precision industrial networks is a complex problem since the industrial applications are resource-critical, time-critical, session-less, and safety-critical. These requirements make existing end-to-end transport mechanisms unsuitable for use in the industry verticals that require control-systems type communication. This paper proposes a lightweight, connection-less, and reliable protocol called TinTin. It utilizes the in-network capabilities to compensate for end device constraints. The mechanisms adopted in TinTin aim to reduce the communication overheads associated with well-known connection-oriented protocols. This paper discusses the design considerations of TinTin in detail and presents an early stage proof-of-concept implementation of TinTin with New IP. © 2022 IEEE.Item Operations and Control Networks (OCN) Model: A Systematic Approach to Operational and Information Technology Convergence(Association for Computing Machinery, Inc, 2023) Makhijani, K.; Li, R.; Tahiliani, M.; Westphal, C.; Dong, L.Convergence between Operational Technology (OT) and Information Technology (IT) remains an aspirational goal due to the lack of a systematic integrated approach. The next-generation Industry 4.0 will automate operations even more, involving different degrees of coordination, multiple locations, applications, and organizations. Eventually, the network's capabilities and technologies will integrate OT and IT. This paper presents a reference model called Operations and Control Networks (OCN), whose components are abstract exchange points between which automation takes place. Such network model for process control can be used as a tool for system integrators and operators to design and analyze their OT networks. It enables OT applications to be developed independently of the underlying network infrastructure. We discuss principles, interfaces, and examples of this model. © 2023 ACM.
