Ever-increasing network applications and constant evolution in basic services are driving optimizations to network architectures. HD video has already become a basic service operator offer as 2K and 4K become more mature. Different from the web traffic patterns of the past, HD video, especially 2K and 4K, require sustained transmission performance and throughput – the first challenge being enhancing network bandwidth. Optical network builds merely lay the framework for carrying 2K and 4K services. Studies have shown that user experience is the main focus to securing success for operators. Providing the ultimate 2K/4K service experience demands transformations to the network to deeper levels, including simplification of the metropolitan area network, intelligent optimization of transmission capacity, and greater agility in operations and maintenance.
Improvements in bandwidth require upgrades to the access, MAN, and core layers. The FBB access layer usually provides 50-100 Mbit/s access, which means improvements require extending copper access with Vectoring and G.fast or fiber-to-the-home placements. Upgrades in the MBB access layers in the 4G era include GE/PON connections to eNodeB, any media access in small cell backhaul, and 10GE CPRI backhaul. Improvements to bandwidth at the MAN and core layers require finding ways to enhance router capacity and use of WDM transmission technology to improve throughput.
Simplifying MAN networks involves reducing the number of layers on the network – flattening the network. FBB uses vBNG while MBB uses vIPRAN and other virtualization technologies to streamline network equipment layouts, which in turn reduces O&M and equipment costs. These technologies are what help build bearers able to handle 4K and 4.5G mobile services. Service configuration uses seamless MPLS to achieve end-to-end streamlining and reduce O&M costs. Improvements in performance are mainly aimed at reducing the buffering in 2K and 4K, improving video quality, increasing speed in channel switching, and delivering on other requirements in providing a superior experience. Intelligent broadband acceleration with high-throughput routers (HTRs) provides accurate and effective acceleration programs in diverse transmission scenarios to enhance throughput. Open network capability platforms (NetOpen) achieve smooth integration in service management between operator BSS systems and third-party content providers, raising the service experience standard.
Huawei has geared into the new challenges of the Internet age with development of IP FPM technologies to achieve agile O&M. These technologies enable operators to perceive user experience at the millisecond level and refined down to differentiated service levels of each user group as opposed to the previous gauging that could only be carried out at the minute level and only at the overall network level. This new precision in real-time quality of experience means operators are able to provide greatly improved levels of network management and responsiveness. Rounding out the optimizations, visualization of KQIs and KPIs on the back-end systems delivers a unified user and network experience.
