Increasingly, the use of fiber optic cable as a transport for voice, data, video, and Internet traffic is becoming the norm. SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy) are being used with high-speed data transmission. Although SONET/SDH was originally intended for use in broadband ISDN and support leased line services like DS-1 and DS-3. SONET/SDH expansion is being fuelled by many of today's biggest industries such as Boeing, Disney and AT&T as these companies move their internal global networks to a SONET/SDH infrastructure. This work provides coverage of SONET/SDH technology written at a level that will be understandable to technicians working in the telecommunications industry. It includes detailed examples of DWDM (dense wavelength division multiplexing) and WDM (wavelength division multiplexing).

MPLS is many things to many people. If you're moving IP voice traffic, it may mean performance gains for you. Daniel Minoli's "Voice Over MPLS" gives you the technical and business lowdown on innovative new solutions for packet-based voice. What does it take to build flexible, high-performance networks with enhanced quality of service? Maybe not as much as you think. Reliable voice services that customers can afford. With VoMPLS, you can deliver the quality associated with VoIP over ATM links without the cost in either bandwidth or equipment. Based on label-switching standards from the IETF and the work of a number of leading companies, "Voice over MPLS" lets you packetize voice without the added overhead of IP encapsulation. It also suppresses periods of silence, freeing up bandwidth for other uses.From one of the most experienced names in telecom technology, "Voice Over MPLS" shows you how to - provide multiple, high-quality services without costly leased lines; deliver low-bandwidth voice over ATM, Frame Relay, or IP; add phone "lines" without adding equipment; solve scaling issues for small- and medium-sized users; obtain consistent call quality without crunching bandwidth; discover ways to protect revenues during deployment; evaluate the potential role of VoMPLS in big-picture convergence; and evaluate VoMPLS's impact on public networks. Here, you find the engineering details you need for Label Switched Paths (LSPs), layers, signaling, CoS (Classes of Service), QoS (Quality of Service), VoMPLS in VPNs (Virtual Private Networks), implementation options, deployment, and more.

Because of their small, portable nature, PDAs present a unique security dilemma. This is the essential reference for PSA technicians and IT professionals who need to understand and solve this challenge. Written by a security expert, the book explores PDA security issues and details what must be done to establish privacy in the hand-held medium. It: covers the vast variety of devices available, including Palm, PocketPC, and RIM devices; includes foreword by Rebecca Bace, internationally recognized intrusion detection and network security specialist; includes a case study guide - "PDA Defense - Palm's Choice for Enterprise"; explains why handheld security is largely about OS (Operating Systems); explores hacking problems; answers the questions - when does a handheld become an IT problem and what is a measured IT response?
