Active Queue Management: A Survey

Richelle Adams
2013 IEEE Communications Surveys and Tutorials  
Of interest is the role of AQM in QoS provisioning particularly in the DiffServ context, as well as the role of AQM in the wireless domain.  ...  In this survey we discuss the general attributes of AQM schemes, and the design approaches taken such as heuristic, control-theoretic and deterministic optimization.  ...  The core (or DS Domain), the tag on the packet (and without regard to what flow it belongs), will forward it accordingly. So instead of the more complex per-flow QoS, there is aggregate QoS.  ...

A softwarized perspective of the 5G networks [article]

Kleber Vieira Cardoso, Cristiano Bonato Both, Lúcio Rene Prade, Ciro J. A. Macedo, Victor Hugo L. Lopes
2020 arXiv   pre-print
A significant part of the article is dedicated to 5G networks and beyond, focusing on core, i.e., considering the Service-Based Architecture (SBA), due to its relevance and totally softwarized approach  ...  The article explores the use of software in the 5G system composed of the Radio Access Network (RAN) and the core components, following the standards defined by 3GPP, particularly the Release 15.  ...  In this way, an SA architecture consolidates the concept of decoupling of the data and control planes, allowing flexible and stateless positioning of virtual environments in the different network segments  ...
