Voice Over Ip Services

The complete resource for understanding and deploying IP quality of service for Cisco networks Learn to deliver and deploy IP QoS and MPLS-based traffic engineering by understanding: QoS fundamentals and the need for IP QoSThe Differentiated Services QoS architecture and its enabling QoS functionalityThe Integrated Services QoS model and its enabling QoS functionsATM, Frame Relay, and IEEE 802.1p/802.1Q QoS technologies and how they work with IP QoSMPLS and MPLS VPN QoS and how they work with IP QoSMPLS traffic engineeringRouting policies, general IP QoS functions, and other miscellaneous QoS information Quality-of-service (QoS) technologies provide networks with greater reliability in delivering applications, as well as control over access, delay, loss, content quality, and bandwidth. IP QoS functions are crucial in today's scalable IP networks. These networks are designed to deliver reliable and differentiated Internet services by enabling network operators to control network resources and use. Network planners, designers, and engineers need a thorough understanding of QoS concepts and features to enable their networks to run at maximum efficiency and to deliver the new generation of time-critical multimedia and voice applications. "IP Quality of Service" serves as an essential resource and design guide for anyone planning to deploy QoS services in Cisco networks. Author Srinivas Vegesna provides complete coverage of Cisco IP QoS features and functions, including case studies and configuration examples. The emphasis is on real-world application-going beyond conceptual explanations to teach actual deployment. "IP Quality of Service" is written for internetworkingprofessionals who are responsible for designing and maintaining IP services for corporate intranets and for service provider network infrastructures.

The insider's guide to IP-based telephony: development, network deployment, testing, and beyond Now that virtually every leading telecommunications service provider has committed to delivering IP-based telephony services, communications professionals face the enormous challenge of implementation. This hands-on guide brings together today's best-known answers and solutions for delivering Voice Over IP (VoIP) services with the quality customers demand. No other book covers the combined issues of protocol signaling, media transport methodology, reference topological considerations, and voice quality testing in service offerings. Bill Douskalis presents systematic coverage of every aspect of IP-based telephony: Coverage includes: A realistic reference topology for implementing and benchmarking voice quality in IP telephony Detailed explanations of call setup using each major competing technology Signaling, bearer transport, and other key network elements In-depth network and service performance analysis in both "normal" and impaired scenarios State-of-the-art traces and performance measurements taken from actual IP networks No matter what your role in delivering VoIP services, IP Telephony delivers the specifics you need to speed deployment, improve reliability, ensure quality, and simplify troubleshooting. Precise, thorough, and based firmly in the real world, it is simply indispensable. The accompanying CD-ROM contains Hewlett-Packard Internet Advisor software that runs off-line--view live VoIP traffic examples! It also includes sample capture files of the H.323, MGCP, and SIP protocols; the latest IETF Working Group documents for VoIP; and an assortment of whitepapers and application notes that provide a real-world view of IP telephony.

IP Multimedia Subsystem - The IP Multimedia Subsystem (IMS) is a standardised Next Generation Networking (NGN) architecture for telecom operators that want to provide mobile and fixed multimedia services. It uses a Voice-over-IP (VoIP) implementation based on a 3GPP standardised implementation of SIP, and runs over the standard Internet Protocol (IP).
