Deliverable D2.1 - Ecosystem analysis and 6G-SANDBOX facility design

This document provides a comprehensive overview of the core aspects of the 6G-SANDBOX project. It outlines the project's vision, objectives, and the Key Performance Indicators (KPIs) and Key Value Indicators (KVIs) targeted for achievement. The functional and non-functional requirements of the 6G-SANDBOX Facility are extensively presented, based on a proposed reference blueprint. A detailed description of the updated reference architecture of the facility is provided, considering the requirements outlined. The document explores the experimentation framework, including the lifecycle of experiments and the methodology for validating KPIs and KVIs. It presents the key technologies and use case enablers towards 6G that will be offered within the trial networks. Each of the platforms constituting the 6G-SANDBOX Facility is described, along with the necessary enhancements to align them with the project's vision in terms of hardware, software updates, and functional improvements

A multimedia traffic scheduler for IEEE 802.16 point-to-multipoint networks

In this paper, we describe and evaluate an advanced traffic scheduler for IEEE 802.16 Point-to-Multipoint networks, referred to as “Colored Frame Registry Tree Scheduler” (C-FRTS). The main characteristics of this scheduler are i) the use of a tree structure to prepare the creation of time frame maps and reduce processing requirements at the beginning of each frame, and ii) a colored discrimination of packets scheduled for transmission to guarantee the bandwidth reserved for different connections. Simulation results show that C-FRTS can guarantee major QoS parameters, such as the maximum latency and the minimum and maximum reserved bandwidth, as well as provide differentiated treatment to the various service types
