A diversity of technical advances in the field of network and systems virtualization have made it possible to consolidate and manage resources in an unprecedented scale. These advances have started to come out of the data centers, spreading towards the network service provider (NSP) and telecommunications operator infrastructure foundations, from the core to the edge networks, the access network, and the customer premises LAN (local area network). In this context, the residential gateway (RGW) constitutes an ideal candidate for virtualization, as it stands between the home LAN and the access network, imposing a considerable cost for the NSP while constituting a single point of failure for all the services offered to residential customers. This chapter presents the rationale for the virtual RGW (vRGW) concept, providing an overview of past and current implementation proposals and discussing how recent technological developments in key areas such as networking and virtualization have given a competitive edge to a RGW virtualization scenario, when compared with traditional deployments.

The combination of a high-speed wireless network with passive optical network technologies has led to the evolution of a modern integrated fiber wireless (FiWi) access network. Compared to broadband wireless networks, the FiWi network offers higher bandwidth with improved reliability and reduced maintenance costs due to the passive nature of passive optical network (PON). Since the quality of service (QoS) is a baseline to deploy high-speed FiWi broadband access networks, therefore, it is essential to analyze and reduce the typical problems (e.g., bandwidth and delay) in the high-speed next-generation networks (NGANs). This study investigates the performance of a fiber wireless architecture where a 10-Gigabit-capable passive optical network (XGPON) and fifth generation of wireless local area network (WLAN) (i.e., IEEE 802.11ac) are integrated. Both technologies take benefits from each other and have pros and cons concerning the QoS demands of subscribers. The proposed work offers a very flexible QoS scheme for the different types of services of 5G WLAN and XGPON with the help of the highest cost first (HCF) algorithm, which leads to reduced upstream delays for delay-sensitive applications. The simulation results show that the HCF algorithm boosts the performance of the dynamic bandwidth assignment (DBA) scheme and results in up to 96.1%, 90.8%, and 55.5% reduced upstream (US) delays for video: VI(T2), background: BK(T3), and best effort: BE(T4) traffic in enhanced-distributed-channel-access (EDCA) mode. Compared to earlier work, the HCF and immediate allocation with the colorless grant (IACG) DBA combination results in the reduction of up to 54.8% and 53.4% mean US delays. This happens because of 50% to 65% better bandwidth assignment by the IACG DBA process due to efficient mapping by the HCF algorithm.

Seeing wireless technology in action around us today, it is difficult to image that just about 20 years ago, the technology and the industry were still in their infancy. Wireless technology has grown in leaps and bounds in the last few years. It is also mind bogging to imagine what will happen to the technology in the next 10 years, if it keeps the current pace. Wireless technology is a new technology that started in the early 1970s. The rapid technological developments of the last 20 years have seen wireless technology as one of the fastest developing technologies of the communication industry. Because of its ability and potential to make us perform tasks while on the go and bring communication to areas where it would be impossible with traditional wired communication, wireless technology has been embraced by millions. There are varying predictions all pointing to a phenomenal growth of wireless technology and the industry. To meet these demands and expectations, comprehensive communication infrastructure based on wireless networking, technology based on wireless local area network (LAN), wide area network (WAN) and Web, and industry based on wireless communication devices are being developed.

The objective of this paper is to report findings from simulating and testing local area network (LAN) connectivity using Windows XP operating system and Cisco Networking Academy network devices. In this study, a simple routing protocol, RIP, is used as routing protocol. Two different techniques, Cisco Networking Academy hardware lab and Cisco Packet Tracer 4, were used to compare their performance to simulate network connectivity. Primary findings showed that the settings of the Windows XP firewall on the host computer have a direct impact on the test results. These findings are critical as there are no similar reports in the literature and only a careful investigation allowed the researchers to come to this conclusion. Furthermore, study results also offer suggestions for fixing problems that hinder simulation results of LANs that use Windows XP workstations. These findings can help CCNA students and faculty understand the reasons for unexplained connectivity problems when performing CCNA labs. The study also provides a simple method to avoid connectivity problems when using Windows ping.exe and tracert.exe which implement the TCP/IP protocol ICMP

PT Aplikanusa Lintasarta Project Management and Resource Management (PMRM) division has the task to providing network services and manage networks that are used both for PT Aplikanusa Lintasarta and clients. PMRM division has several problems, one of which is the replacement and addition of network devices used so that it must do a new network configuration. One of the solutions offered is to implement a Local Area Network (LAN) in PMRM division. This network implementation is needed because the network at the company will someday develop more along with the many users and technological developments. LAN implementation uses several network devices, like a router, switch, network cable (UTP cable), and PC or laptop as user. Some of features that used in this LAN network are website blocking, (Dynamic Host Configuration Protocol) DHCP, Hotspot, and bandwidth. Testing on LAN networks is done by calculating throughput, delay, and packet loss. This test is needed to find out how well LAN network works.

Abstract A local area network (LAN) consists typically of several telecommunication nodes, all of which share a public IP address and a single point of contact with the Internet, namely the router. For an outside observer, the whole LAN with all its nodes would look point-like (having one, shared, "public IP" address and a single connection with the Internet), but in its interactions it would appear field-like, as a LAN of several nodes, each with its own "private IP" address, has an internal structure and interacts with the outside world differently than a single node would. In this study, the above particle/LAN analogy will be used as a basis of Átmiton theory, according to which, elementary particles are made of LANs consisting of a type of telecommunication node - called átmiton - and space is a 3D network of átmita with the simple cubic topology. In this work, it is demonstrated that connecting a particle/LAN entity on the lattice of space distorts its local topology, effectively introducing a crystal defect to the lattice of space. This defect increases the distance between points lying at opposite sides of it. The internal interactions of any massive object should be producing constantly copious numbers of such space-defects, which diffuse away from their source, by means of a random walk. Here it is suggested that general relativity's notion of spacetime's curvature is equivalent to the aforementioned diffusion-driven impurity model in the flat, discrete lattice of space of Átmiton theory. Their equivalency is demonstrated for the specific case of a spherical mass, around which the Schwarzschild metric is shown to be valid.
