Today's networks support a great variety of services with different bandwidth and latency requirements. To maintain high user satisfaction and efficient resource utilization, providers employ traffic shaping. One such mechanism is the Hierarchical Token Bucket (HTB), allowing for two-level flow bitrate guarantees and aggregation. In this demo, we present HTBQueue -our OMNeT++ realization of the HTB, and show how the module can be used for mimicking 5G network slicing and analyzing its effect on network services.

“…Traffic shaping formats the traffic to the desired profile by delaying some or all packets and can be applied to improve QoS, optimize or guarantee performance, or expand usable bandwidth. Traffic shaping has been implemented in prior research on edge computing [56] and resource allocation [57].…”

5G network slicing is a promising solution to prioritize time-critical protection communication in wireless networks. However, recent trends indicate that a 5G slice could encompass all smart grid applications lacking the necessary granularity. At the same time, while substation communication standards recommend prioritization of protection communication traffic to improve reliability, these recommendations are only for wired connections. Therefore, this paper investigates traffic shaping and uplink (UL) bitrate adaptation of video stream based on existing commercial solutions as methodologies for prioritizing the protection communication in a 5G slice. These methodologies are validated in an experimental setup combining controller-hardware-in-the-loop (CHIL) simulation with a quality of service (QoS) measurement system. The system under test consists of commercial 5G networks, commercial intelligent electronic devices (IEDs), and merging units to validate the methodologies on three smart grid applications: fault location, line differential, and intertrip protection. The results show improvement in protection communication when traffic shaping and UL bitrate adaptation are applied. Traffic shaping even improves prioritization with a wired connection.

<p>The visions of 5G and Beyond (B5G) imply unprecedented expectations toward high-performing connectivity services in both public and private networks. Connectivity services that offer performance guarantees along multiple Quality of Service (QoS) dimensions are partially available today, but are confined to (virtual) private network services. However, open and equal access to public and Internet-scale Specialized Connectivity Services (SCS) delivered on-demand with interconnections across networks and support for mixed traffic modes that go beyond traditional best effort does not exist. In this paper, we argue that this is a huge industrial and societal problem that needs a solution. However, this problem is highly complex and multifaceted, and there are many reasons why we are more or less locked into the status quo. The paper identifies the stumbling blocks and proposes a set of solution elements to take us across these hurdles, alongside related research topics. This includes an approach to “Multi-Level Best-Effort (MLBE)” and evolved net neutrality. Models and simulations are provided showing how a mixed traffic mode approach provides anticipated benefits. Arguments are given why the context brought by B5G will put us into conditions for change, allowing public SCS eventually at a global scale.</p>
