Dynamic QoS Management for a Flexible 5G/6G Network Core: A Step toward a Higher Programmability

Abstract

The academic and professional community has recently started to develop the concept of 6G networks. The scientists have defined key performance indicators and pursued large-scale automation, ambient sensing intelligence, and pervasive artificial intelligence. They put great efforts into implementing new network access and edge computing solutions. However, further progress depends on developing a more flexible core infrastructure according to more complex QoS requirements. Our research aims to provide 5G/6G core flexibility by customizing and optimizing network slices and introducing a higher level of programmability. We bind similar services in a group, manage them as a single slice, and enable a higher level of programmability as a prerequisite for dynamic QoS. The current 5G solutions primarily use predefined queues, so we have developed highly flexible, dynamic queue management software and moved it entirely to the application layer (reducing dependence on the physical network infrastructure). Further, we have emulated a testbed environment as realistically as possible to verify the proposed model capabilities. Obtained results confirm the validity of the proposed dynamic QoS management model for configuring queues’ parameters according to the service management requirements. Moreover, the proposed solution can also be applied efficiently to 5G core networks to resolve complex service requirements.

The course on modern 5G/6G networks: A step toward understanding a flexible network core

“…So, in front of the researchers is to define and identify the role of QoS and QoE in 6G networks, especially regarding network infrastructure management. The authors in [5] expect that further progress is dependent on developing a more flexible network core infrastructure according to more complex QoS requirements. They propose a new network slicing model to provide 5G/6G core flexibility by customizing and optimizing network slices and introducing a higher level of programmability.…”

“…Container orchestration is also relevant in 5G/6G network slicing, enabling dynamic service provisioning. We provide supplemented material in the form of teaching slides in the Serbian language in reference [4].…”

Detection Collision Flows in SDN Based 5G Using Machine Learning Algorithms

“…Programmable functionalities should be moved from network devices to centralised application controllers. SDN [19] algorithms inform the network what to do in reaction to network modifications or dynamic flow pattern alterations. Numerous different device setups are eliminated due to central management.…”

“…However, due to the difficulties of traffic diversification and the inappropriate design of the control and data planes, Quality of Service (QoS) [19] provisioning is the biggest issue in existing [20] networks. End-to-end QoS [21] support in existing network designs is a persistent issue.…”

Server-side adaptive bitrate method based on perceptual video quality in networks with controllable bandwidth

“…Recently, to handle the network congestion and quality of service (QoS) requirements of services, a QoS-managed network virtually partitioned for service, such as network slicing in 5G, was developed. Furthermore, to address more complex requirements, research is being conducted on the dynamic QoS management [1] for networks and the network exposure function that enables QoS management by external applications through the API. In video streaming, The HTTP adaptive bitrate(ABR) algorithm is used in major delivery methods such as MPEG-DASH and HLS.…”
