2649G-8 For mission-critical voice, data, and video traffic, yesterday's "best effort" Internet delivery is no longer enough. The solution: Quality of Service (QOS)-a family of techniques that enable service providers and companies to guarantee specific levels of wide area network performance. In this book, leading telecommunications consultant Uyless Black explains all aspects of WAN quality of service, giving communications professionals all the information they need to implement them, and deliver services based on them. Coverage includes: * How QOS works-and why it is crucial to networks that must deliver integrated voice, data, and video traffic * Implementing QOS in IP, ATM and frame relay environments * Leveraging QOS capabilities built into IPv4 and IPv6 * Mastering the Resource Reservation Protocol (RSVP), Real-Time Transport Protocol (RTP), and DiffServ * Establishing and enforcing QOS guarantees in business networks * Understanding Layer 4 QOS-capable devices that prioritize data traffic using transport-layer criteria Quality of Service in Wide Area Networks also includes detailed coverage of using QOS for delivery of integrated services; and of Multiprotocol Label Switching (MPLS), the new Internet standard that promises to seamlessly integrate routing control, while increasing network scalability and reducing complexity. Whether you're a service provider, corporate telecommunications professional, or internetworking product developer, you need to understand QOS technologies-and with this authoritative guide, you will.
