Performance Isolation for Network Slices in Industry 4.0: The 5Growth Approach

Abstract

Network slicing plays a key role in the 5G ecosystem for verticals to introduce new use cases in the industrial sector, i.e., Industry 4.0. However, a widely recognized challenge of network slicing is to provide traffic isolation and concurrently satisfy diverse performance requirements, e.g., bandwidth and latency. Such challenge becomes even more important when serving a large number of network traffic flows under a resource-limited condition between distributed sites, e.g., factory floor and remote office. In this work, we present the capability to retain these two goals at the same time, by applying the virtual queue notion over a priority queuing based pipeline in P4 switch over software-defined networks. To examine the effectiveness of our approach, a proof-of-concept is setup to serve different requests of Industry 4.0 use cases over a mixed data path, including P4 switch and Open vSwitch, for a large number of network flows.

An Empirical Assessment of the Contribution of 5G in Vertical Industries: A Case for the Transportation Sector

“…By combining these aspects with 5G's New Radio (NR) ability to allow the dynamic allocation of bandwidth partitions to offer different classes of traffic [9], network slicing allows for differentiating network service provisioning towards different devices and users in the same coverage area [10]. This ability is of great importance to verticals, as their traffic needs to be isolated from other data flows for different reasons, such as performance [11] and security [12]. Additionally, 5G also brings new possibilities that benefit existing scenarios and technology directions, such as Cellular Vehicle to Everything (C-V2X).…”

“…The infrastructure, showcased in figure 1, contains a deployment of the SONATA 10 Management and Orchestration (MANO) Service platform, which has been deployed in other research projects such as H2020 5GTANGO 11 . It consists of several components running as microservices and interacting with each other to manage the lifecycle of Virtual Network Functions (VNF), Network Services (NS), and slices.…”

Enabling P4 Network Telemetry in Edge Micro Data Centers With Kubernetes Orchestration

“…Few works in literature use P4Runtime to control P4-based devices, most of them leverage on Bmv2 and ONOS SDN controller. The work in [47] demonstrates the compatibility of P4Runtime and Openflow devices operating in the same network under the control of the single SDN controller, guaranteeing performance isolation among multiple network slices. The work in [48] implements a benchmarking tool for P4Runtime-based controllers and applies the tool to evaluate the performance of the ONOS controller running in both OpenFlow and P4Runtime mode.…”

Intent-based zero-touch service chaining layer for software-defined edge cloud networks

“…Indeed, a coordinated control of both cloud-and network-layer resources is recommended in order to provide adaptive service data delivery and adequate user service experiences [58]. In our previous works, concatenated connectivity in computing networks (i.e., into data-center/cloud networks) was also investigated [59] and we also contributed to an end-to-end service chaining including connectivity in edge clouds [60] or within network slicing for industry 4.0 [61]. Latency, adaptability and availability requirements were also investigated in [62].…”
