Citynet Deploys Infinera DTNs for Next-Generation Optical Backbone; U.S. Mid-Atlantic/Midwestern Carrier Gains Strategic Service and Operational Advantages by Deploying Digital Optical Networking Technology.SUNNYVALE, Calif. -- Infinera Corporation today announced that Citynet has deployed Infinera's DTN See disruption-tolerant network and delay-tolerant network. platform on a significant portion of its network after completing an intense nine-month lab and field trial of Infinera's hardware, software and EMS components. Citynet is a leading wholesale IXC (1) (IntereXchange Carrier) An organization that provides interstate (long distance) communications services within the U.S., which includes AT&T, MCI, Sprint and more than 700 others. See LATA. (2) (IXC Communications Inc., Austin, TX, www. carrier with an extensive 8000 route mile network footprint that serves the domestic Mid-Atlantic and Midwestern markets. Citynet offers an array of bandwidth solutions that provide many of the nation's leading wireless and wireline voice, data, and Internet carriers with highly reliable bandwidth solutions into the company's Tier 2 and Tier 3 markets as well as regional Tier 1 markets. "Network reliability is the cornerstone of our wholesale services and we recognize that our clients entrust their brand equity to Citynet. For that reason, 99.999% carrier class reliability is always our number one priority. Infinera's platform proved to be more than capable of meeting our stringent requirements" said Mike Friloux, COO of Citynet Wholesale. Citynet selected Infinera because of the significant strategic advantages offered by Infinera's "Digital Optical Networking Communications between computers, telephones and other electronic devices using light. An optical network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain. See optical fiber. " technology. These include the delivery of high-bandwidth optical services more quickly and flexibly than the competition, the capability to offer new services such as 10 Gigabit Ethernet An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. , as well as improved network reliability and service manageability. Incorporating Infinera's own "photonic integrated circuit A Photonic Integrated Circuit (PIC) is a device that integrates multiple photonic functions and as such is analogous to an Electronic Integrated Circuit. However the major difference between the two being that a photonic integrated circuit provides functionality for information " (PIC) technology, the Infinera DTNs provide the industry's most-advanced dense wave-division multiplexing (DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing ) and digital bandwidth management Controlling the traffic flow in a network. See bandwidth manager. capabilities and will support the increased demand Citynet is seeing for optical wavelength (2.5 - 10 Gbps), private line (DS3 - OC192 and Ethernet), and IP-based service offerings. "We see Infinera's photonic integrated circuits as the most innovative technology in optical networking since WDM (1) (Wavelength Division Multiplexing) A technology that uses multiple lasers and transmits several wavelengths of light (lambdas) simultaneously over a single optical fiber. emerged in the mid-1990s," said Friloux. "Infinera's DTN allows us to drop any amount of our core bandwidth at any location on our network, bypassing the restrictive features of legacy analog-based DWDM systems. This translates into more bandwidth options for our customers while maximizing the returns of our growth capital. The strategic value for us is a highly adaptive infrastructure that allows us to shape, groom, and distribute our bandwidth based on the changing demands of our customers. Harnessing this flexibility required us to embrace the reality that electronics are and will remain the dominant force for providing intelligence in the network. This is where Infinera's Digital Optical Networking approach matched the reality of our day-to-day challenges." Infinera's product architecture is unique in the industry because of its use of large-scale photonic integrated circuits. Infinera's PICs convert all optical traffic at a given location into electronic signals, which can then be digitally processed. This digital bandwidth management capability is the essence of the Digital Optical Networking concept, which results in simpler planning, engineering, and operations; faster service delivery; and a more reliable and flexible network. "We were able to install, test, and turn up our first 1100 kilometer ring in three days. Other systems would have required at least four to five times as long," said Friloux. "But most importantly, adding new customer circuits is extremely fast and easy. With Infinera's digital add/drop and GMPLS-based provisioning, we can rapidly deliver big bandwidth to our customers, when and where they need it." "Given Citynet's experience with wholesale private line and optical wave services, as well as their position as a key partner to many carriers, they immediately saw the advantages of a Digital Optical Network," said Jagdeep Singh, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Infinera. "We're pleased to help them further enhance their service offerings." The Infinera DTN combines DWDM, digital bandwidth management, and GMPLS-based network intelligence. The DTN supports 800 Gb/s of DWDM capacity and delivers a variety of manageable and protectable SONET/SDH and Ethernet-based services, including 10 Gigabit Ethernet LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. PHY See physical layer and physical. . The DTN runs Infinera's IQ(TM) Network Operating System An operating system that is designed for network use. Normally, it is a complete operating system with file, task and job management; however, with some earlier products, it was a separate component that ran under the OS; for example, LAN Server required OS/2, and LANtastic required DOS. , which makes its digital bandwidth management possible, provides a rich set of performance monitoring capabilities, and supports automated network discovery, configuration, and provisioning via GMPLS (Generalized Multiprotocol Label Switching) In a WDM optical networking system, it is the ability to route a data transmission based on the wavelength of light that carries it. .
