Se empleó metodología cuantitativa apoyada en encuestas y entrevistas a personal técnico del GAD Durán, usuarios internos y externos. El proyecto contó con apoyo total de la Dirección de Tecnologías de Información facilitando permisos y datos relevantes. Los criterios de diseño se basan en las recomendaciones y los estándares definidos por la UIT (Unión Internacional de Telecomunicaciones). Se realizó una estimación económica de la implementación de la red óptica, el software de control y seguridad lógica. Se obtuvo el valor de $74,693.83 gracias a colaboración de ZCMAYORISTAS.

  • Powercomm: World’S Largest Metro Ethernet Deployment
    CASE STUDY PowerComm: World’s Largest Metro Ethernet Deployment PowerComm is a facility-based telecommunications carrier and is a subsidiary of KEPCO, Korea's National Electric Power Corporation. PowerComm operates the largest high-quality, fiber comm optic network in Korea and is building a nation-wide, high-speed telecommunications network. PowerComm is the first national telecommunications carrier to deploy an all-Ethernet metropolitan area network in Korea based on advanced Riverstone service-creation routers. PowerComm is installing over 1,000 Riverstone routers in the greater Seoul metropolitan area to create the world's largest metro Ethernet network. PowerComm’s next-generation network will unify its cable and last-mile Ethernet sub-networks, allowing the national carrier to offer its own advanced telecommunications services while leasing the network to other service providers in Seoul and neighboring areas. PowerComm’s Network Infrastructure PowerComm’s network consists of over 60,000 km of optical fiber and over 4,000 km of High Frequency Cable (HFC) network throughout Korea. PowerComm’s objective is to provide fair and reasonable access to its telecommunications network for companies and service providers, enhancing competition in the telecommunications industry in accordance with the Korean government’s goal to restructure the public sector. The optical fiber network leverages KEPCO’s electrical power transmission towers and electrical distribution pylons throughout Korea, reaching even the most remote regions of the country. The network provides facility-based telecommunications service providers with a stable and high-quality infrastructure. PowerComm’s customers include: • Wireless communication providers that lease telecommunication facilities, such as exchanges, base stations, and relay stations.

It presents common Ethernet implementations in service- provider networks, the testing requirements to ensure reliable service, as well as installation and maintenance techniques. Following its introduction in the early 1970s, the Ethernet protocol for data networking has been characterized by ever-increasing popularity and adaptation. In recent years, Ethernet has become the predominant network access protocol, now used in over 95% of all local-area networks. With the advent of Gigabit Ethernet and 10 Gigabit Ethernet, this technology has matured and made its way from local-area networks to metropolitan-area networks, and now wide-area networks, challenging traditional transport protocols such as SONET/SDH and ATM. www.exfo.com Guide Ethernet.1-ang: Guide Ethernet.1AN 5/7/07 10:06 AM Page 1 Table of Contents 2.7 Ethernet Frame Tag ..............................................................................23 2.8 VLAN Tagging........................................................................................23 Symbols Used in Illustrations................................................3 2.9 Traffic Priority ........................................................................................25 2.10 Frame Bursting ......................................................................................26

  • Understanding Ethernet
    Chapter 1 Understanding Ethernet In This Chapter ▶ Exploring carrier sensing and collision detection methods ▶ Understanding directional traffic and simultaneous transmissions ▶ Examining Ethernet speed limits and wire-rated standards ▶ Exploring Gigabit Ethernet ▶ Distinguishing between local and backbone Ethernet ▶ Recognizing Ethernet interfaces ▶ Understanding Ethernet’s simplicity n today’s connected business world, ubiquitous access to Idigitized information and data is critical. Networking has not only reshaped the information landscape, but it has also vastly increased speeds at which information moves and is consumed. In fact, networking is the key to accessing the com- plex services and applications within which information plays a starring role. Although access to the Internet is essential, all networking begins at the local level. For modern networks, Ethernet is the standard infrastructure upon which local net- works rest. Ethernet comprises a family of frame-based protocols and tech- nologies designed to connect local area networks (LANs) — computersCOPYRIGHTED and devices situated in MATERIAL close proximity and able to communicate with one another. Ethernet draws its name from the fanciful Latin terminology luminiferous aether, which trans- lates to a light-bearing medium once thought to fill space and propagate magnetic waves. As such, Ethernet is a metaphorical reference for the physical transmission medium in the work- place (and at home) that propagates digitized information in electronic form. The term “Ethernet” was originally coined by 4 Carrier Ethernet For Dummies Bob Metcalfe while jointly developing basic Ethernet network computing with David Boggs at Xerox Palo Alto Research Center (PARC). Sensing a Carrier and Handling Collisions Two people on opposite ends of a phone conversation can sense carrier presence (either a dial-tone or a connected call) and handle collisions (overlapping conversations).
