Service providers are increasingly focused on delivering triple-play bundles that incorporate Internet, video, and VoIP servicesaas well as multi-play bundles containing even more advanced services. Broadband Network Architectures is the first comprehensive guide to designing, implementing, and managing the networks that make triple-play services possible. Hellberg, Greene, and Boyes present their field-tested industry best practices and objectively evaluate the tradeoffs associated with key up-front architectural decisions that balance the complexities of bundled services and sophisticated traffic policies. Broadband Network Architectures not only documents what is possible on this rapidly changing field of networking, but it also details how to divide Internet access into these more sophisticated services with specialized Quality of Service handling. Coverage includes Am An in-depth introduction to next-generation triple-play services: components, integration, and business connectivity Am Triple-play backbone design: MPLS, Layer 3 VPNs, and Broadband Network Gateways (BNGs)/Broadband Remote Access Servers (B-RAS) Am Protocols and strategies for integrating BNGs into robust triple-play networks Am Triple-play access network design: DSLAM architectures, aggregation networks, transport, and Layer 2 tunneling Am VLAN-per-customer versus service-per-VLAN architectures: advantages and disadvantages Am PPP or DHCP: choosing the right access protocol Am Issues associated with operating in wholesale, unbundled environments Am IP addressing and subscriber session management Am Broadband network security, including Denial of Service attacks and VoIP privacy Am The future of wireless broadband: IMS, SIP, and non-SIP based fixed mobile convergence and wireless videoA 20Mbps ADSL2+ connection could support HDTV, VoIP, and Internet simultaneously if traffic is correctly prioritized. ... Higher data bit-rate DSL such as ADSL2+ and VDSL are being adopted, and other FTTx-type services such as Verizona#39;s FIOS are gaining in the market. ... For example, issues that are still being debated, such as acommon carrier status, a could punctuate the broadband landscape withanbsp;...
