This document discusses real-time operating systems (RTOS) and real-time Linux. It begins with an overview of operating systems and their tasks before discussing what real-time means in terms of deterministic and predictable response times. It then describes what qualifies as a real-time operating system and provides some examples. The document notes that while Linux can support some real-time capabilities, it was not designed as a RTOS. It explores some real-time Linux options like RTAI, Xenomai, and PREEMPT-RT that aim to enhance Linux's real-time performance and determinism. It also briefly mentions the LITMUS RT testbed for evaluating real-time scheduling algorithms on multiprocessors

RT linux
RTLinux is a real-time operating system that allows real-time applications to run on top of Linux. It modifies the Linux kernel to add a virtual machine layer with a separate task scheduler that prioritizes real-time tasks over standard Linux processes. This enables RTLinux to support hard real-time deadlines. Programming in RTLinux involves creating modules that can be loaded and unloaded from the kernel using specific commands. Real-time threads and synchronization objects like mutexes are implemented using POSIX interfaces.

The hague rina-workshop-mobility-eduard
1) The ARCFIRE project is experimentally validating the benefits of RINA technology through large-scale experiments on the FIRE+ testbed involving over 100 nodes across multiple distributed information fields (DIFs).
2) In RINA, application names uniquely identify applications, addresses are location-dependent synonyms used for locating applications within a DIF, and other identifiers like port-ids and connection endpoint IDs are used to identify communication endpoints.
3) RINA's naming and addressing model simplifies multi-homing and mobility by assigning addresses to nodes instead of interfaces, avoiding the need for special protocols and allowing mobility to be treated as dynamic multi-homing with expected failures.

3 Phase NFV/SDN Virtualizartion Road Map
Virtualization offers unprecedented benefits in terms of agility, service innovation and reduced cost. But transforming an infrastructure could be a difficult task unless planned properly. Mettle Networks proposes a virtualization road map that progresses in three distinctive phases. It helps to handle both technical and cultural challenges of virtualizing a legacy infrastructure in this step by step approach.
Support formobility
This document discusses problems with HTTP and HTML for mobile devices and proposes solutions. HTTP was designed for high-bandwidth, low-delay connections and results in large headers, uncompressed content transfers, and overhead from separate TCP connections for each page item. Caching is also often disabled on dynamic pages. HTML assumes desktop computers rather than mobile constraints. Solutions proposed include image scaling, content extraction, new protocols, push technologies, and enhanced caching through client and network proxies.

Tech Talk by John Casey (CTO) CPLANE_NETWORKS : High Performance OpenStack Ne...
OpenStack is HOT! No doubt about it. A recent survey by The New Stack and The Linux Foundation shows OpenStack as the most popular open source project ahead of other hot projects like Docker and KVM. OpenStack is now taking its rightful place as the open source cloud solution for enterprises and service providers.
To date OpenStack networking has not yet achieved the performance, scalability and reliability that many large enterprises demand. CPLANE NETWORKS solves that problem by delivering secure multi-tenant virtual networking that overcomes the limitations of the standard Neutron networking service. By making all networking services local to the compute node and achieving near line-rate throughput, CPLANE NETWORKS Dynamic Virtual Networks (DVN) delivers mega-scale networking for the most demanding application environments.
In this session John Casey will cover the basics of DVN and explain how CPLANE NETWORKS achieves "at scale" network performance within and across data centers.

Redes LTE Comunitárias no Brasil: Modelamento, Implantação e Manutenção Sustentáveis com base em Novos Paradigmas de Redes.
Projeto financiado pela FAPESP Processo: 18/23101-0
Resumo
Em relatório publicado pelo Comitê Gestor da Internet no Brasil (CGI.br) em 2018, em termos de acesso à Internet por banda larga no Brasil, há uma ampla desigualdade entre as classes econômicas A/B (maior) e D/E (menor), fato evidenciado nas análises entre as áreas urbanas e rural. Além de evidenciar que cerca de 34% dos brasileiros ainda não possuem acesso à Internet, o relatório também explica que o acesso à Internet é um catalisador de desenvolvimento social, econômico e tecnológico: fato consagrado em diversas pesquisas internacionais e enfatizado pela organização Internet Society. Redes sem fio comunitárias têm se tornado um meio sustentável de promover meios acessíveis de conexão à Internet,tanto em áreas rurais remotas quanto em regiões urbanas densas. Em sua ampla maioria, redes sem fio comunitárias adotam a tecnologia wifi, no entanto apenas recentemente, devido ao desenvolvimento de tecnologias de código livre e de baixo custo, o padrão Long-Term Evolution (LTE) começou a ser explorado para estes fins. Logo, não há conhecimento na literatura acadêmica de estudos que busquem utilizar e melhorar o padrão LTE aplicado à redes sem fio comunitárias. Nesse escopo, esta proposta busca trazer conceitos inovadores de novos paradigmas de redes, Redes Definidas por Software (Software Defined Networks -SDN) e Virtualização de Funções de Rede (Network Functions Virtualization - NFV), para o desenvolvimento de redes LTE comunitárias. Por meio de uma metodologia ágil de testes,conceitos de SDN e NFV serão aplicados no desenvolvimento de mecanismos que realizem o gerenciamento inteligente de recursos de redes LTE comunitárias visando desempenho eficiente e tolerância a falhas robusta, i.e., a sustentabilidade da rede. Todos estes estudos serão feitos tendo por base um levantamento de características de redes sem fio comunitárias em operação no Brasil proposto para o início do projeto. Ao final, a execução desta proposta irá produzir um material didático elucidando as formas de modelamento, implantação, e manutenção sustentável de uma rede LTE comunitária nos moldes dos estudos realizados por esta proposta (i.e., com todos os dados, avaliações, metodologias, e protótipos). Este material será utilizado como base de uma proposta de implantação de uma rede LTE comunitária no Brasil junto ao programa "Beyond the Net" da Internet Society.

3rd Workshop on Advances in Slicing for Softwarized Infrastructures (S4SI 2020)
Panel: Network Slicing is multifaceted but does its approach and understanding need to be fragmented?
Abstract: Network Slicing keeps growing in significance in the academic and industrial communities. Network Slicing can be defined from different functional or behavioral perspectives, as well as from different viewpoints depending on the stakeholder (e.g., verticals, solution providers, infrastructure owners) and the technical domain (e.g. cloud data centers, radio access, packet/optical transport networks). Standardization bodies and open source projects are being involved in some forms of network slicing support. How far are these views from each other? Is fragmentation leading to incompatible approaches or is there some hope of convergence, at least at conceptual levels? What is the next frontier in Network Slicing? These and other questions will be thrown to our panel experts after introducing their lightning viewpoints.

NECOS Industrial Workshop lightning talk by Prof. Nelson Fonseca (UNICAMP) Christian Esteve Rothenberg
The document proposes a network slicing technique for IEEE 802.11ah networks that dynamically manages radio resources by reconfiguring Restricted Access Window (RAW) parameters over time. A Virtual Network Slicing Broker is introduced as a virtual network function that defines network slices based on service features and quality of service restrictions. It communicates with an IEEE 802.11ah access point to monitor network statistics and enforce slicing configurations using a static or dynamic approach. Simulation results show the dynamic approach allows the broker to reallocate resources between slices by updating the RAW configurations, improving overall network performance.NECOS Industrial Workshop lightning talk by Jorge Seki (CPqD / 5G-RANGE)

Network slicing allows building logical networks on a shared infrastructure. Each slice is designed for a business purpose and comprises all required resources. Slices are created, changed, and removed by management functions. Slices are defined using Network Slice Templates that describe the structure, components, and configuration. Network Slice Instances are realized by configuring and instantiating resources and network functions. Automation is key to managing the complexity of multiple slices.NECOS Industrial Workshop lightning talk by Alessandro Nascimento (Nokia)

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
