whitepaper Advanced Intelligence in Cisco Multiservice Transport Product2007-01-01 Cisco Systems
  The advent of Reconfigurable Optical Add/Drop Multiplexer (ROADM) technology and mesh optical networks challenges the operating model for transport service providers, with SONET/SDH moving to the edge and even being replaced by Layer 2 and Layer 3 traffic. Traditional point-to-point Wavelength-Division Multiplexing (WDM) becomes complex all-optical networking, eliminating the need for large Digital Cross-Connect (DXC) switch points. The superior optical intelligence brought to the field by the Cisco ONS 15454 MultiService Transport Platform (MSTP) reverses the whole paradigm, making the all-optical network easier to operate than standard traditional SONET/SDH OEO-based technology.

whitepaper Sun StorageTek T10000 Fibre Channel Tape Drive - Raising the Bar of Performance: A Performance Comparison Test by Percept Technology Labs, Inc.2007-01-01 Sun Microsystems
  The need for data storage is becoming more critical than ever. Rigorous compliance regulations recently enacted worldwide, for example, now mean that failure to recover data can do more than just compromise the company's competitive position; it can incur stiff legal penalties, as well. The Sun StorageTek T10000 tape drive system was developed with all of this in mind. Specifically, the T10000 delivers industry-leading data throughput performance that enables fast-paced companies to cope with the challenges of doing business in today's world - by helping them to quickly backup their data stores while minimizing system "Down-time." This technical paper demonstrates why the T10000 is the ideal choice for businesses that simply cannot afford to cut corners when it comes to data accessibility.

whitepaper Next Generation OTN Transport Solution2007-01-01 ECI Telecom
  A new transport technology is required to provide a converged transport solution for TDM and packet-based services. The Optical Transport Network (OTN) technology introduces such a solution, while offering flexibility for new services. The Optical Transport Hierarchy, OTH, is a new transport technology developed by the ITU for utilizing the experience and benefits of SONET/SDH and DWDM technologies. It enables the transfer of client signals (packet-based and legacy TDM services) over multiservice transport networks. It has all the capabilities to monitor, manage, and control each particular wavelength in the network.

whitepaper IBM DB2 9 on AIX 5L With NFS, iSCSI, and FCP Using IBM System Storage N Series2007-01-01 IBM
  Ethernet bandwidth is eclipsing Fibre Channel and the cost of Ethernet is becoming more affordable than Fibre Channel. One question that has arisen is how NFS and iSCSI perform in comparison to FCP. This paper provides a performance comparison and tuning recommendations for three different transport protocols, FCP, iSCSI, and NFS, when IBM DB2 V9 and AIX 5L 5.3 TL-04 are run on a 2-way IBM System p5 520 server using an IBM System Storage N5500. An OnLine Transaction Processing (OLTP) workload was used to study the performance.

whitepaper Complexity of Wavelength Assignment in Optical Network Optimization2006-12-09 01:00:18 Alcatel-Lucent
  This paper studies the complexity of a spectrum of design problems for optical networks in order to carry a set of demands. Under Wavelength Division Multiplexing (WDM) technology, demands sharing a common fiber are transported on distinct wavelengths. Multiple fibers may be deployed on a physical link. The basic goal is to design networks of minimum cost, minimum congestion and maximum throughput.

whitepaper Line System Design for DWDM Networks0000-00-00 Alcatel-Lucent
  State-of-the-art Dense Wavelength Division Multiplexing (DWDM) allows data transport with very high capacity, measured in terabits per second, and very long reach, thousands of kilometers. One current DWDM technology arranges network elements into line systems, where a line system is a path consisting of alternating network elements and optical fibers. A line system is a linear sequence of network elements (OADMs) and fibers, all optically transparent. This paper describes algorithms for partitioning a DWDM mesh network into line systems, given a demand matrix.

whitepaper Cooperative Data-Optical InterNetworking: Distributed Multi-Layer Optimization2006-12-09 01:00:18 Alcatel-Lucent
  This paper presents a novel approach for joint optical network provisioning and IP traffic engineering, in which the IP and optical networks collaboratively optimize a combined objective of network performance and lightpath provisioning cost. A framework is developed for distributed multi-layer optimization. This framework is built upon the IP-over-Optical (IPO) overlay model, where each network domain has a limited view of the other. The formulation allows the two domains to communicate and coordinate their decisions through minimal information exchange. The solution is based on a novel application of Generalized Bender's Decomposition, which divides a difficult global optimization problem into tractable sub-problems, each solved by a different domain.

whitepaper Inspection and Cleaning Procedures for Fiber-Optic Connections2006-09-26 Cisco Systems
  Clean fiber optic components are a requirement for quality connections between fiber optic equipment. One of the most basic and important procedures for the maintenance of fiber optic systems is to clean the fiber optic equipment. It is important that every fiber connector be inspected and cleaned prior to mating. This paper describes inspection and cleaning processes for fiber optic connections. The procedures in the paper describe basic inspection techniques and processes of cleaning for fiber optic cables, bulkheads, and adapters used in fiber optic connections.
