whitepaper A leading worldwide telecommunication network equipment manufacturer needed to design the main digital component of a radio link SDH system product. It was intended to implement a radio terminal providing regeneration and adaptation functionality...
[10 Apr 2008]
whitepaper The forces behind Synchronous Digital Hierarchy (SDH)/Synchronous Optical Network (SONET) have answered the competition and now the Ethernet in the metro has been challenged by new technology called next-generation SDH, which provides Ethernet...
[10 Apr 2008]
whitepaper Learn the principal sources of SONET/SDH jitter, the reasons previous testers gave such widely differing measurements, and the new ITU-T 0.172 process for accurately calibrating jitter signals.
[10 Apr 2008]
whitepaper This white paper is an introduction to Cisco Systems optical and storage product offerings, with a focus on the new SL-Series Fiber Channel/FICON over SONET/SDH interface card for the Cisco ONS 15454, and the Cisco MDS 9000 Family.
[10 Apr 2008]
whitepaper The SDH signal has built-in performance monitoring, maintenance, provisioning, and operations information directly within the signal format. SDH networks will increasingly incorporate intelligent network elements for more flexible network...
[10 Apr 2008]
whitepaper There are a number of standards, which are relevant in this area, and the paper concentrates on the Timing characteristics of SDH Equipment Slave Clocks (SEC). This paper describes the complexity of the high-speed networks by analyzing different...
[10 Apr 2008]
whitepaper A Global 500 financial services firm had the challenge to utilize readily available SONET/SDH bandwidth for the extension of disk mirroring to meet escalating data storage and BC requirements. Global implemented CIENA's CN 2000 that was designed to...
[10 Apr 2008]
whitepaper This paper discusses the factors that need to be considered when extending FC SANs over existing MAN/WAN infrastructures, and summarizes the three options in extension technologies: IP/Ethernet networks, Wavelength Division Multiplexing (WDM...
[10 Apr 2008]
whitepaper The Quad-Port Gigabit Ethernet (GbE) over SONET/SDH design is a system solution for transporting GbE frames over existing SONET/SDH rings or point-to-point connections. It is provided using a combination of SONET/SDH and GbE standard products...
[10 Apr 2008]
whitepaper A Global 500 financial services firm faced a number of critical data storage and network infrastructure issues. The firm was generating a tremendous amount of transaction and collaborative data, creating new levels of storage requirements and...
[10 Apr 2008]
whitepaper This paper reviews the current Ethernet product offerings for the Cisco ONS 15454 multi-service provisioning platforms (MSPPs) and then discusses how they can be applied to deliver scalable, high-speed, reliable data services today.
[10 Apr 2008]
whitepaper These networks are based in part on fiber-optic telecommunications infrastructure, including network architectures of Synchronous Optical Network (commonly referred to as SONET), the North American standard for synchronous data transmission; and...
[10 Apr 2008]
whitepaper FPL implemented CIENA's CN 2000 Storage Extension Solution which extends up to 16 Fibre Channel (FC), Gigabit Ethernet (GbE), ESCON, and FICONTM applications across any SONET/SDH, WDM, or Dark Fiber network through DS3, OC-3/12/48, or STM-1/4/16...
[10 Apr 2008]
whitepaper This white paper demonstrates how to overcome the historical limitations of Ethernet and defines the carrier-grade requirements for Optical Ethernet solutions so service providers can benefit from the carrier-grade features of SONET/SDH without...
[10 Apr 2008]
whitepaper The Lucent Universal Packet Mux (UPM) presents a significant contribution in this direction, through collapsing the transport aspects of Ethernet, VPLS/MPLS, SDH/SONET, WDM/OTN and GMPLS into a scalable and flexible platform.
[10 Apr 2008]
whitepaper Both of these interfaces support transmission at 9.6 Gbps, support SONET/SDH framing, and can be connected to SONET/SDH ADM or DWDM gear. The introduction of 10 Gigabit Ethernet (10 GbE) WAN PHY into the IP/Ethernet networking community has led to...
[07 Feb 2008]
whitepaper This paper proposes mathematical programming models for the design of two-layer networks where MPLS is considered on top of transport networks (SDH or WDM depending on required link speed). The possibility of adding MPLS support to transport...
[11 Jan 2008]
whitepaper To maintain its competitive advantage in the fast-growing Turkish GSM market, Avea is planning to evolve its core transport network by deploying high capacity next-generation SDH equipment. Avea is a dynamic player in Turkey's mobile communications...
[10 Jan 2008]
whitepaper The paper studies a planning problem arising in SDH/WDM multi-layer telecommunication net-work design. The goal is to find a minimum cost installation of link and node hardware of both network layers such that traffic demands can be realized via...
[08 Jan 2008]
whitepaper Emerging technologies, like RPR, POS and GE, are being pushed to replace the traditional SONET/SDH and ATM in WAN. This paper evaluates performance issues of RPR, POS and GE on a testbed, including fault recovery, network stress, QoS and multicast...
