  • Evolution of Access Network Sharing and Its Role in 5G Networks
    applied sciences Review Evolution of Access Network Sharing and Its Role in 5G Networks Nima Afraz * , Frank Slyne , Harleen Gill and Marco Ruffini * CONNECT Centre, Trinity College, The University of Dublin, 2 Dublin, Ireland; [email protected] (F.S.); [email protected] (H.G.) * Correspondence: [email protected] (N.A.); marco.ruffi[email protected] (M.R.) Received: 3 October 2019; Accepted: 18 October 2019; Published: 28 October 2019 Abstract: This paper details the evolution of access network sharing models from legacy DSL to the most recent fibre-based technology and the main challenges faced from technical and business perspectives. We first give an overview of existing access sharing models, that span physical local loop unbundling and virtual unbundled local access. We then describe different types of optical access technologies and highlight how they support network sharing. Next, we examine how the concept of SDN and network virtualization has been pivotal in enabling the idea of “true multi-tenancy”, through the use of programmability, flexible architecture and resource isolation. We give examples of recent developments of cloud central office and OLT virtualization. Finally, we provide an insight into the role that novel business models, such as blockchain and smart contract technology, could play in 5G networks. We discuss how these might evolve, to provide flexibility and dynamic operations that are needed in the data and control planes. Keywords: access networks; network sharing; 5G networks; multi tenancy; optical access; sharing economics 1. Introduction By its nature, a telecommunications network is a shared resource that interconnects multiple nodes. Network sharing is part of a fundamental principle of statistical multiplexing of link capacity.

  • Telecom Basics
    Basic Concepts of Telecommunication [Part 1] Prepared By : Tilak De Silva - Expert Assisted By : Chandima Ranasinghe 25.11.2005 Telecom Basics 1. What is a telephone Access Network? The network used to connect the telephone-to-telephone exchange. 2. What is Wired and Wireless? The connection between telephone and exchange can be two copper wires or radio wave. If copper wires are used it is called wired connection. It is required two wires to connect the telephone and exchange. It is called a local loop. This connection also can be provided by a radio wave. It is called a Wireless Local Loop (WLL). 3. What is a fixed telephone? If the telephone is not moved from its position it is called a fixed telephone. 4. Who are the fixed line operators in Sri Lanka? Sri Lanka Telecom Suntel Bell - 1 - SLT provides both wired and wireless local loops. Suntel and Bell provides wireless local loops only, therefore they are called WLL operators. 5. Show the path of wired connection 6. What are the devices/Stages involved to a wired connection? Telephone exchange MDF Cabinet DP Telephone 7. What is the function of telephone exchange? When a telephone dials a number it is received by the telephone exchange and analyses the number and connect to the relevant telephone via the remote exchange. For the calls received from the remote exchange the originated telephone exchange checks whether the relevant telephone is free or busy. If the telephone is busy the busy tone is sent to the other exchange. If the telephone is not busy the ring back tone is sent to the other exchange.

SYSTEMS DESCRIPTION: 01. Telecommunications requirements at the University of Baltimore continue to increase in variety and complexity. It is unlikely that this situation will change in the future. Voice, data and video requirements will vary over time, and will be different for each department and function of the University, but the trend will be towards more and faster communications capabilities. The lack of a modern cable plant has hampered progress in expanding data communications in particular. 02. This standard for telecommunications wiring is designed to meet the specific current needs of the University, and to permit growth and flexibility in the future. In addition to describing the twisted pair and/or fiber network required to deliver communications to the desktop, specifications are included for installation of a fiber optic cable backbone connecting buildings. Data requirements include the need for different levels of Ethernet from 100Mb to 10Gb over unshielded twisted copper pairs and Fiber.
