With video traffic accounting for more than 60% of the global downstream Internet traffic in 2019, video streaming represents a significant portion of inbound traffic to the home environment. Recently, the Internet Engineering Task Force (IETF) has standardised three Active Queue Management (AQM) schemes – PIE (RFC8033), CoDel (RFC8289) and FQ-CoDel (RFC8290). These schemes are being progressively deployed at the last-mile Internet Service Providers’ (ISP) end-points and home gateways to counteract bufferbloat and will likely impact consumer video streams. This talk presents the benefits of the emerging AQM schemes in broadband networks and their impact on video streaming traffic and an experimentally validated technique that has been proposed for improving streaming performance in typical consumer home broadband environments.

THE FUTURE OF HYBRID FIBRE COAXIAL CABLE NETWORK TECHNOLOGY
- Date: 2 Sept 2020
- Time: 12:30 PM to 01:45 PM
- Registration: https://telsoc.org/event/future-hybrid-fibre-coaxial-cable-network-technology
The future of Hybrid Fibre Coax (HFC) is very important for Australia’s National Broadband Network (NBN), with HFC passing more than 3 million premises. In this presentation the speaker will discuss a potential future for the HFC, driven by the CableLabs’ “10G project”, leading to DOCSIS 4.0. The stages in an NBN upgrade and some of the likely barriers to implementation will be outlined. All this will be set in a context of changing end-user requirements and evolving network capabilities.
NBN – “NEW BROADBAND NORMAL”
- Date: 26 Aug 2020
- Time: 12:30 PM to 01:45 PM
- Registration: https://events.vtools.ieee.org/m/237087
The world and broadband now evolve to a new normal. A centennial pandemic suddenly intensifies our broadband dependency and mandates more ubiquitous and reliable communication everywhere, including Australia’s NBN. What does this mean for broadband evolution plans? What must change? What can change? Fiber to everyone’s wristwatch was never an economically viable solution, but there are paths that address need and viably advance into the new altered future. Existing facilities’ combined intelligent leverage, and best use of advanced, powerful, and distributing computing can indeed provide viable solutions. This talk investigates such paths, how to measure their advance, and suggests paths that transcend well into tomorrow’s New Broadband Normal.

ENERGY-EFFICIENT SCHEDULING FOR WIRELESS NETWORK SLICING

In 5G networks, mobile service providers will support vertical slices of mobile applications to meet diverse service quality requirements, such as ultra-low latency, densely distributed users and high reliability. Meanwhile, wireless traffic is explosively growing, driven by widespread mobile communication devices and increasing popularity of mobile applications. The wireless network slicing technique, which is built on network function virtualization and software defined network schemes, will support wireless applications on substrate physical facilities with higher flexibility and lower cost.
A scheduling policy for wireless network slicing should maximize the energy efficiency of the network. (Here, we define energy efficiency as the ratio of long-run average throughput of user requests to the long-run average power consumption.) This is a problem of extremely high computational complexity, which prevents direct application of conventional optimization techniques. We have developed a policy called Most Energy-Efficient Resource First (MEERF), which is scalable and priority-based. MEERF is asymptotically optimal in a local wireless environment with highly dense user population and exponentially distributed service times. Our extensive simulations show the robustness of MEERF to different service time distributions. We also show the effectiveness of MEERF compared to benchmark policies in a more general network with potentially geographically distributed users and infrastructures.

5G ELECTROMAGNETIC FIELDS: EXPOSURE LEVELS AND SAFETY STANDARDS
- Date: 10 Jun 2020
- Time: 05:00 PM to 06:30 PM
- Registration: https://events.vtools.ieee.org/m/231252
The presentation will provide a brief introduction to 5G and what it means for electromagnetic (EMF) exposure based on the results of assessments of 5G networks (commercial and pilot) conducted in Australia and overseas. The international EMF exposure guidelines were updated in March 2020 and one of the major changes was to provide more detailed guidance for frequencies above 6 GHz. Independent public health agencies say that no health risks are expected for 5G but myths and misinformation continue to be spread on social media, including suggestions of a link between wireless technologies and COVID-19. Pointers will be provided to reliable sources of information.
