Layer 2 VPN Architectures /by Wei Luo (Author), Carlos Pignataro (Author), Anthony Chan (Author), Dmitry Bokotey (Author) .The historical disconnect between legacy Layer 2 and Layer 3 VPN solutions has forced service providers to build, operate, and maintain separate infrastructures to accommodate various VPN access technologies. This costly proposition, however, is no longer necessary. As part of its new Unified VPN Suite, Cisco Systems® now offers next-generation Layer 2 VPN services like Layer 2 Tunneling Protocol version 3 (L2TPv3) and Any Transport over MPLS (AToM) that enable service providers to offer Frame Relay, ATM, Ethernet, and leased-line services over a common IP/MPLS core network. By unifying multiple network layers and providing an integrated set of software services and management tools over this infrastructure, the Cisco® Layer 2 VPN solution enables established carriers, IP-oriented ISP/CLECs, and large enterprise customers (LECs) to reach a broader set of potential VPN customers and offer truly global VPNs.

Coverage Control in Sensor Networks /by Bang Wang (Author).This easy-to-read text focuses on challenges in coverage control in sensor networks, examines fundamental coverage problems, and presents the most recent advances and techniques in the field. Features: provides an introduction to sensors, sensor nodes, sensor networks, and sensor coverage models; supplies an informal definition and taxonomy for network-wide coverage control; explores the node placement optimization problem for coverage configuration before network deployment; investigates the coverage lifetime maximization problem by controlling coverage characteristics in a randomly deployed network; discusses the critical sensor-density problem for coverage configuration before network deployment; examines the sensor-activity scheduling problem of controlling network coverage characteristics in a randomly deployed network; introduces the node movement strategy problem for sensor networks containing mobile nodes; presents the challenges of building intrusion barriers and finding penetration paths.

Managing Cisco Network Security /by Sean Thurston (Author). An in-depth knowledge of how to configure Cisco IP network security is a MUST for anyone working in today's internetworked world "There's no question that attacks on enterprise networks are increasing in frequency and sophistication..."-Mike Fuhrman, Cisco Systems Manager, Security Consulting
Managing Cisco Network Security, Second Edition offers updated and revised information covering many of Cisco's security products that provide protection from threats, detection of network security incidents, measurement of vulnerability and policy compliance and management of security policy across an extended organization. These are the tools that network administrators have to mount defenses against threats. Chapters also cover the improved functionality and ease of the Cisco Secure Policy Manger software used by thousands of small-to-midsized businesses and a special section on the Cisco Aironet Wireless Security Solutions. Security from a real-world perspective
Key coverage of the new technologies offered by the Cisco including: 500 series of Cisco PIX Firewall, Cisco Intrusion Detection System, and the Cisco Secure Scanner
Revised edition of a text popular with CCIP (Cisco Certified Internetwork Professional) students
Expanded to include separate chapters on each of the security products offered by Cisco Systems

Building Telephony Systems with OpenSIPS 1.6 /by Flavio E. Goncalves (Author) .SIP is the most important VoIP protocol and OpenSIPS is clearly the open source leader in VoIP platforms based on pure SIP. The whole telecommunication industry is changing to an IP environment, and telephony in the way we know today will disappear in less than ten years. SIP is the protocol leading this disruptive revolution and it is one of the main protocols on next-generation networks.While a VoIP provider is not the only kind of SIP infrastructure created using OpenSIPS, it is certainly one of the most difficult to implement.
This book will give you a competitive edge by helping you to create a SIP infrastructure capable of handling tens of thousands of subscribers. You can extend the examples given in this book easily to other applications such as a SIP router, load balancing, IP PBX, and Hosted PBX as well. This book is an update of the title Building Telephony Systems with OpenSER.
The book starts with the simplest configuration and evolves chapter by chapter teaching you how to add new features and modules. It will first teach you the basic concepts of SIP and SIP routing. Then, you will start applying the theory by installing OpenSIPS and creating the configuration file. You will learn about features such as authentication, PSTN connectivity, user portals, media server integration, billing, NAT traversal, and monitoring. The book uses a fictional VoIP provider to explain OpenSIPS. The idea is to have a simple but complete running VoIP provider by the end of the book.
* Identify how SIP transactions are routed including initial and sequential requests
* Accelerate the processing of SIP sequential requests with the help of Loose Routing
* Install OpenSIPS in a Linux platform and integrate a media server such as Asterisk
* Acquire authentication and persistency by enabling a MySQL back-end for OpenSIPS
* Administer the server with the help of graphical web interfaces such as OpenSIPS control panel and serMyAdmin
* Connect to a PSTN gateway to send and receive calls
* Enable dynamic dial plans and routing by using the DIALPLAN module DROUTING module
* Traverse NAT using STUN and TURN
* Bill your costumers or simply check your expenses by generating CDRs (Call Detail Records)
* Monitor your SIP infrastructure to keep it running smoothly

Wireshark & Ethereal Network Protocol Analyzer Toolkit /by Angela Orebaugh (Author), Gilbert Ramirez (Author), Jay Beale (Author).Ethereal is the #2 most popular open source security tool used by system administrators and security professionals. This all new book builds on the success of Syngress' best-selling book Ethereal Packet Sniffing.

This book provides complete information and step-by-step Instructions for analyzing protocols and network traffic on Windows, Unix or Mac OS X networks. First, readers will learn about the types of sniffers available today and see the benefits of using Ethereal. Readers will then learn to install Ethereal in multiple environments including Windows, Unix and Mac OS X as well as building Ethereal from source and will also be guided through Ethereal's graphical user interface. The following sections will teach readers to use command-line options of Ethereal as well as using Tethereal to capture live packets from the wire or to read saved capture files. This section also details how to import and export files between Ethereal and WinDump, Snort, Snoop, Microsoft Network Monitor, and EtherPeek. The book then teaches the reader to master advanced tasks such as creating sub-trees, displaying bitfields in a graphical view, tracking requests and reply packet pairs as well as exclusive coverage of MATE, Ethereal's brand new configurable upper level analysis engine.
