Net Working Trends

Introduction

Computer technologies and communication networks need to be available and accessible anytime and anywhere. Current network architectural design should ensure that network utilities are accessible from any device. Current networks are highly evolving to support and incorporate new technologies, support new classes of applications as well as support new services.  New network requirements involve proper mitigation of insecurity challenges.  Networks designs should scale and adapt to unforeseen events, vulnerabilities, and uncertainties across multiple network support utilities. Current network designs include different types of applications, storage size, and topology, wireless mobility patterns, and incorporates heterogeneity of devices and networking technologies that enhance security. Current networks design incorporate needs for enhancing easily control using manageable application. Network architectures are currently designed with adequate resources and energy efficient and effective support of the growth of traffic and users virtually. Major network architecture integrates secure and resilient procedures to prevent failures and attacks. Networking Technology and Systems (NeTS) involves the use of programs that supports transformative research.  NeTS integrate fundamental and scientific technologies that advance in networking as well as systems. NeTS promote high-performance networks and future Internet architectures.

The information and communication technology (ICT) industry is experiencing very dramatic changes in networking architecture. The current environments are embracing virtual technologies developed using VMware technology. The growth and development of IT have led to great transformations in the field of distribution of network resources.  Various essential resources can be shared such as repository systems, storage locations and hardware and software components. Trends in network technology and are a major trigger and driving forces for the evolution of future networks. New network infrastructures are expected to implement 5th Generation (5G) architectural design. The current changes in paradigm include changes in design and operations of networks and its services. Various changes such as rise of cloud networking, the rise towards

Virtualized Networks and Infrastructure

Software Defined Networking (SDN) and Software Defined Infrastructure (SDI) are being used in recent network infrastructures to facilitate high-level potential in acting as major drivers of network innovation.  SDN and SDI design are being incorporated into networks to enable novel network functionality, wired and wireless network domains. In network systems, NeTS architecture is being improved and transformed by technologies associated that support SDN and SDI (Lee, Murray, & Qiao, 2015). The current trends that have been implemented in current network technology include. Current trends of networks involve embedding techniques for mapping applications onto virtualized infrastructure. Applications installed in network infrastructures include securing and monitoring systems such as analysis tools. Another improvement includes embedding resources such as performance enhancing tools such as Hadoop servers and databases to support big data concepts.  Current networks infrastructures are supported using resilience systems such as the installation of data recovery and backup systems.

Another trend involves managing virtualized infrastructures through the allocation of resources to various network system users. Current networks are designed to support network of things. Network resources are dynamically changed and shifted among users especially in cases where the virtualized infrastructures are dynamically shared. New 5th generation protocols for controlling of virtualized infrastructure are being incorporated in modern network architecture. Novel virtualization techniques that enhance the easier accessibility of network resources as well as availing network in mobile devices are being applied in wireless networks (Lee, Murray, & Qiao, 2015). The new wireless support operations include incorporation of spanning the home technology, easy access hot spots, enterprise virtual network infrastructures for wireless devices and cellular network domains.

Wireless Network Architectures

Current trends have a diverse multitude of wireless network architectures that are emerging to support communication. Techniques currently are applied to enhance the development of conventional wireless network infrastructures for effective communication design principles. Various trends wireless techniques are associated with novel physical layer techniques as well as virtual technological trends. The various wireless trends that are applied to enhance novel technologies use of Ultra-wideband millimeter-wave wireless networks that enhance spanning frequencies above 20 gigahertz (Sukant et al., 2015). The bandwidth allows streaming of various multimedia applications such as video conferencing, real-time chatting, among other business operations. Trends in wireless architectures incorporate free-space optics and visible light communications that enforce high-level securities due to strong privacy, confidentiality, and personalization. Current trends in wireless architectures have promoted features such as high-bandwidth network systems that enhance streaming of data and information across wireless devices. Wireless architectural designs have incorporated agile frequency to provide multiple and standardized resource allocation. Mobile devices can generate shared bandwidth through establishing peer connection. Bandwidth can be transformed to wired architecture through the implementation of airborne communication platforms. Airborne communication platforms have also facilitated the development of manned and unmanned systems that implement wireless technology.  Drones, as well as high-altitude balloons, are being used as modern aircraft for controlling and managing security. Drones are effectively applied in surveillance for terror attacks.

New wireless architecture support systems by promoting pervasive machine to machine communications at large scale. The trend has facilitated implementation of highly functioning systems that are energy-harvesting. The energy can be easily distributed across devices to minimize and reduce energy consumption. Trends in wireless systems involve the implementation of ultra-low power sensors that enhances minimization of power consumption. The power-oriented systems enable perpetual operations within wireless networks. Such technologies have facilitated direct implementation of a dynamic spectrum of access; the technology has facilitated effective and efficient support of various technology-based communication. The technology has facilitated dynamic utilization in radio systems such as radio frequency identification systems (RFID) (Sukant et al., 2015). Wireless systems have facilitated cognitive of radios frequencies within communication sector.

Virtual Networks

Virtualization has improved computing and information technology through enhancing server consolidation and support to the cloud computing.  Virtualization technology is one of most dominant computing platform worldwide. Through virtualization, network security has been highly improved in current network architectures. Techniques such as the application of VMware technologies have led to various ways in which security has been enhanced in modern network infrastructures (Sperotto, et al., 2015). Current trends in networked systems are defining new ways in which security can be improved via network virtualization techniques.

Virtual Networks have the ability to micro-segment network traffic to create pervasive virtual firewalls. The virtual firewalls are usually software-based which are distributed across the data center. Virtual Networks have resonated in the market through implementation of VMware technology. Implementation of the virtual network has created a variety of new opportunities for having improved security practices. Virtual Networks have improved network security such as protection on perimeter defenses. It has also facilitated the improvement of security by ensuring security on traffic inside of the data centers, databases, and other repository locations. One way Virtual Networks has achieved security measures is through virtual micro-segmentation implemented through VMware technology (Wen, Tiwary, & Le-Ngoc, 2015). VMware architecture as part of the virtual technology allows new virtual networks to be easily created. It also allows network policies to be easily defined and get assigned to the networks. Virtual technology allows only certain types of traffic to flow across network infrastructures. Virtual systems ensure that network systems have parameters and set methods of dealing with attacks. When an infectious threat attempts to use the network, it is not authorized to access network. Since virtualization supports segmentation of networks, segmented networks provide high-level security through mitigating an attacking agent trying to gain access to the network. Even if intruder succeeds to get in the system, he has no freedom to rein within the data center, databases or repository locations. Intruders are limited and get confined in a single segmented network.

Virtual Networks enhance perimeter security through modifying ability to develop virtual firewalls. Through VMware technology, firewalls get distributed throughout the data center, across databases and server systems. However, in physical network infrastructure configurations and setups, for the physical firewall are implemented. Software and hardware firewalls are still used as a perimeter defense a technology referred to as north and south traffic. It takes security consideration for that is data and information coming into and going out of an environment. New trends in virtual networks technologies, allows virtual firewalls to be placed inside as well as get distributed throughout the data center (Tomovic, Pejanovic-Djurisic, & Radusinovic, 2014). It allows for east and west traffic control, management and monitoring by ensuring and facilitating server to server operations. In virtual networks, all components are protected by virtual firewall rules.

Virtual networks and other application that rely on virtual technologies can be applied in different network segments to enable hiding of utilities from other parties. Networks or applications can be segmented to belong to a specific group of users. Network applications and software can easily be scanned for malware and other attacks. Vulnerability testing on networks can be implemented on network segments (Lee, Murray, & Qiao, 2015).  Activities such as monitoring and checking information flow are more easily on virtual platforms. Security applications which include Intruder Detection Systems (IDS) as well as Intruder prevention systems can run as software inserted applications directly onto the virtual networks. Rather than requiring physical devices virtual interfaces require software applications that can be implemented more effectively across the network rather than on a dedicated system. Another trend in virtual networks is the addition of security intelligence systems and security analytical systems within virtual networks. Intelligence systems can be built into virtualized networks to enhance scanning, and monitoring abnormal activities on the network.

Conclusion

Software Defined Networking (SDN) and Network Function Virtualization (NFV) has changed new ways of network architecture. New architectures are being created taking new opportunities for all network oriented network resources.  New changes include easy, flexibility and programmability of desired network architecture. Network designs have gained openness, and responsiveness while reducing the cost of subscribing to networks. Meanwhile, modern network infrastructure has solved some issues such as network and service management. For future network design will include resulting in emerging networking paradigm (Kim, Kim, & Chung, 2015).   New network infrastructure incorporates information-centric networking and programmable networking to support mobile devices.
