Special Issue Information

Dear Colleagues,

Network slicing is a paradigm that allows the sharing of the same infrastructure for providing differentiated 5G services; thus, service level assurance (SLA) becomes challenging while multiple services with various requirements need to be served simultaneously. There are cases that a single vertical application may be provisioned by multiple slices with resources located from the core to the edge and the 5G RAN, while in other cases, verticals may share part of one slice. OSS/BSS service and network orchestrators need to have a full understanding and a kind of situational awareness of such complex relationships. They need to decide, define, and reorganize slicing solutions, meeting the agreed SLAs for each vertical application in a manner that they “intelligently” facilitate the realization of the “zero-touch network and service management” vision.

Submissions can focus on, but are not limited to, the following topics:

  • Service-based architectures, solutions, and use cases for intelligent 5G slicing and lifecycle management that implement closed-loop automation, FCAPS, service assurance, and “zero-touch network and service management”;
  • Concepts, solutions, and use cases that address the slicing issue in an end-to-end manner, from the core to the edge, including the radio resources as well (or satellite integration in 5G), even in cross-domain/federated cases or in non-public networks;
  • Concepts, solutions, and use cases that provision resources and create 5G network slices by ensuring KPIs like latency, energy consumption, cost reduction, isolation, etc., especially those introduced by ideas like the generic slice template from GSMA, or service profile by 3GPP;
  • Intent-based, AI-driven slice specification and continuous monitoring, management, and adaptation across layers, from network and computing to low-level edge hardware resources;
  • 5G RAN and intelligent slicing;
  • Multi-access edge computing and intelligent slicing;
  • Management models for intelligent slicing.

Network slicing is considered a key technology in enabling the underlying 5G mobile network infrastructure to meet diverse service requirements. In this article, we demonstrate how transport network slicing accommodates the various network service requirements of Massive IoT (MIoT), Critical IoT (CIoT), and Mobile Broadband (MBB) applications. Given that most of the research conducted previously to measure 5G network slicing is done through simulations, we utilized SimTalk, an IoT application traffic emulator, to emulate large amounts of realistic traffic patterns in order to study the effects of transport network slicing on IoT and MBB applications. Furthermore, we developed several MIoT, CIoT, and MBB applications that operate sustainably on several campuses and directed both real and emulated traffic into a Programming Protocol-Independent Packet Processors (P4)-based 5G testbed. We then examined the performance in terms of throughput, packet loss, and latency. Our study indicates that applications with different traffic characteristics need different corresponding Committed Information Rate (CIR) ratios. The CIR ratio is the CIR setting for a P4 meter in physical switch hardware over the aggregated data rate of applications of the same type. A low CIR ratio adversely affects the application’s performance because P4 switches will dispatch application packets to the low-priority queue if the packet arrival rate exceeds the CIR setting for the same type of applications. In our testbed, both exemplar MBB applications required a CIR ratio of 140% to achieve, respectively, a near 100% throughput percentage with a 0.0035% loss rate and an approximate 100% throughput percentage with a 0.0017% loss rate. However, the exemplar CIoT and MIoT applications required a CIR ratio of 120% and 100%, respectively, to reach a 100% throughput percentage without any packet loss. With the proper CIR settings for the P4 meters, the proposed transport network slicing mechanism can enforce the committed rates and fulfill the latency and reliability requirements for 5G MIoT, CIoT, and MBB applications in both TCP and UDP.
