Dynamic Bandwidth Assignment

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.

To Come

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.

Plastic Materials

Plastic materials have many uses. The plastic optical fiber with a low-cost, light weight, good flexibility, big core diameter, easy coupling, anti-electromagnetic interference and electromagnetic radiation, is used for short range communication. This paper analyzed the characteristics of plastic materials and plastic optical fiber, and proposed a novel application technology for access network. In the access network, the plastic optical fiber is used as a transmission medium, from center router to the server, and the various floors of plastic optical fiber switch to the user using plastic optical fiber connections, constitute a plastic optical fiber local area network, to realize the true meaning fiber to the home.
