As Internet audience sizes for high-interest live events reach unprecedented levels and bitrates climb to support formats and applications such as 4K, 8K, and Augmented Reality (AR), live streaming can place a unique type of stress upon network resources. TreeDN is a tree-based Content Delivery Network (CDN) architecture designed to address the distinctive scaling challenges of live streaming to mass audiences. TreeDN enables operators to offer Replication-as-a-Service (RaaS) at a fraction of the cost of traditional, unicast-based CDNs -- in some cases, at no additional cost to the infrastructure. In addition to efficiently utilizing network resources to deliver existing multi-destination traffic, this architecture also enables new types of content and use cases that previously were not possible or economically viable using traditional CDN approaches. Finally, TreeDN is a decentralized architecture and a democratizing technology that makes content distribution more accessible to more people by dramatically reducing the costs of replication.

This document explores the issues involved in the use of edge computing resources to operationalize a media use case that involves an Extended Reality (XR) application. In particular, this document discusses an XR application that can run on devices having different form factors (such as different physical sizes and shapes) and needs edge computing resources to mitigate the effect of problems such as the need to support interactive communication requiring low latency, limited battery power, and heat dissipation from those devices. This document also discusses the expected behavior of XR applications, which can be used to manage traffic, and the service requirements for XR applications to be able to run on the network. Network operators who are interested in providing edge computing resources to operationalize the requirements of such applications are the intended audience for this document.

The IETF Nominating Committee (NomCom) appoints candidates to several IETF leadership committees. RFC 8713 provides criteria for NomCom membership that attempt to ensure NomCom volunteers are members of the loosely defined IETF community, by requiring in-person attendance in three of the past five in-person meetings. In 2020 and 2021, the IETF had six consecutive fully online plenary meetings that drove rapid advancement in remote meeting technologies and procedures, including an experiment that included remote attendance for NomCom eligibility. This document updates RFC 8713 by defining a new set of eligibility criteria from first principles, with consideration to the increased salience of remote attendance. This document obsoletes RFCs 8788 and 8989.

This document provides an overview of operational networking and transport protocol issues that pertain to the quality of experience (QoE) when streaming video and other high-bitrate media over the Internet.

This document explains the characteristics of streaming media delivery that have surprised network designers or transport experts who lack specific media expertise, since streaming media highlights key differences between common assumptions in existing networking practices and observations of media delivery issues encountered when streaming media over those existing networks.
