Datacenter (DC) design has been moved toward the edge computing paradigm motivated by need of bringing cloud resources closer to end users. However, software defined networking (SDN) architecture offers no clue micro DCs (MDCs) for meeting complex and stringent requirements from next generation 5G networks. This is because canonical SDN lacks a clear distinction between functional network parts, such as core elements. Besides, there decoupling routing policy. In this paper, we introduce...

This study conducted a comparative analysis of thirteen metaverse platforms to evaluate their educational potential based on five criteria: avatar customization, browser accessibility, video interaction, external tool integration and environment customization. The research revealed that only the Gather Town platform fully met requirements for an interactive, accessible, personalized learning environment. were categorized into three main categories: gaming, socialization, corporate use,...

Software Defined Networking (SDN) is a promising architectural approach based on programmatic separation of the control and data planes. For high availability purposes, logically centralized SDN controllers follow distributed implementation. While controller role features in OpenFlow protocol allow switches to communicate with multiple controllers, these mechanisms alone are not sufficient guarantee resilient plane, leaving actual implementation as open challenge for designers. This paper...

This paper proposes KAR (Key-for-Any-Route), a new intra-domain resilient routing system in which edge-nodes set route ID to select any existing as an alternative safely forward packets their destination. In system, is defined the remainder of division between and switch IDs along path(s) pair nodes. KAR-enabled switches explore routes by using special properties Residue Number System our encoding technique. Packets are deviated from faulty link (liveness condition) with deflections....

Edge Data Centres (EDC) are often managed by a single administrative entity with logically centralized control. The architectural split of control and data planes the new plane abstractions have been touted as Software-Defined Networking (SDN), where OpenFlow protocol is one common choice for standardized programmatic interface to devices. However, in design an SDN architecture, there no clear distinction between functional network parts such core edge elements. It means that all switches...

Software Defined Networking (SDN) are based on the separation of control and data planes. The SDN controller, although logically centralized, should be effectively distributed for high availability. Since specification OpenFlow 1.2, there new features that allow switches to communicate with multiple controllers can play different roles -- master, slave, equal. However, these alone not sufficient guarantee a resilient plane actual implementation remains an open challenge designers. In this...

To fulfill the emerging demands of mobile users, future networks need to support seamless connectivity. Flexible resource allocation that responds dynamic trends user demand and mobility can be achieved through backhauling supports elastic routing setup teardown paths rapidly as users move adapt. Fortunately, methods such OpenFlow offer necessary capabilities enable a paradigm. This paper investigates suitability in supporting Specifically, herein we compare, on basis reconfigurability...

Network latency is critical to the success of many highspeed, low-latency applications. RFC 2544 discusses and defines a set tests that can be used describe performance characteristics network device. However, most available measurement tools cannot perform all as described in this standard. As novel approach, paper proposes Metherxis, system implemented on general purpose hardware enables Virtualized Functions (VNFs) measure device with micro-second grade accuracy. Results show Metherxis...

Network latency is critical to the success of many high-speed, low-latency applications. In this context, RFC 2544 discusses and defines a set tests that may be used describe performance characteristics network device, but most available measurement tools cannot perform all as described in standard or represent high capital expenses (CAPEX). As novel approach, paper proposes Metherxis, system can implemented on general purpose hardware enables virtualized functions (VNFs) based Linux...

This paper presents an analytical modeling to KAR (Key-for-Any-Route), intra-domain resilient routing system in which edge-nodes set a route ID select any existing as alternative safely forward packets their destination. KAR-enabled switches explore the routes by using special properties of Residue Number System encoding and forwarding techniques. The technique allows adding paths drive deflected (due link failure) original destination so that loops are not formed. Three deflection methods...

Property security represents a set of activities and preventive actions aimed at reducing potential losses in organisations. In this context, electric locks that support different authentication methods, such as passwords, digital keys with tokens, radio frequency identification (RFID) tags, offer improvements access control; however, they represent single barrier protection. article, we propose FaceTag, prototype dual via facial recognition RFID, which has been integrated into an electronic...

On the vast Brazilian beaches, which stretch for more than seven thousand kilometers and attract numerous tourists, safety emerges as a crucial concern. The shortage of lifeguards lack human resources have generated concern due to incidence fatal accidents in bathing areas with low protection coverage. To reinforce security logistics on coast, “Safe Beach” service was created, allows swimmers report emergencies call based their location through an application mobile devices. This article...

Em Data Centers centrados em servidores estes não somente participam no processamento dos dados, mas também encaminhamento do tráfego de rede. geral os são organizados uma topologia conhecida como hipercubo, onde o é feito através simples operações ou-exclusivo. Se por um lado essa simplicidade contribui para aumento da vazão e diminuição latência, outro só funciona caso hipercubo esteja completo, ou seja, na inexistência falhas nó enlace. Este artigo apresenta alternativa, baseada...

Releasing students on leaving school times is a process that requires full attention. In some kindergarten schools, private or public, it possible to find specific professional carry out this mission, however, not uncommon see teachers even other servers performing service. Regardless of who responsible, releasing student an unauthorized person stranger represents terrible security breach for educational institutions. This error can generate trauma and sequelae the life their family members....

O design do datacenter caminha rumo ao paradigma da computação de borda, motivado pela necessidade aproximar os recursos nuvem aos usuários finais. No entanto, a arquitetura SDN não oferece nenhuma orientação para o micro Datacenters suficiente atender requisitos complexos e rigorosos das redes 5G. Isso ocorre porque canônica possui uma distinção clara entre as partes funcionais desta rede, como elementos núcleo borda. Além disso, há desacoplamento roteamento política rede. Na tese,...
