Recently, Huawei released its experience-driven 4K IP bearer network solution. The solution is based on U-vMOS, a video experience evaluation system well-recognized in the industry. U-vMOS helps carriers build IP bearer networks with a superior 4K experience, which ultimately helps carriers become leaders in the 4K era. To cope with this solution, Huawei announced the release of the NE40E-M2H, a 2U, 300 mm deep CO router with the industry-record capacity for a CO router.

Legacy service experience is generally guaranteed if sufficient network bandwidth is available. As 4K services develop, the conventional traffic model of high convergence has transitioned to one featuring high traffic and high concurrency, which makes legacy networks unable to guarantee superior 4K experience. As such, carriers need to construct networks with priority given to throughput instead of bandwidth. Network throughput is closely related to bandwidth, latency, and packet loss rate. To meet the requirements for high bandwidth, low latency, and low packet loss rate in order to achieve 4K experience with a U-vMOS score of 4 or higher, an end-to-end high-throughput IP bearer network is needed.

Huawei's experience-driven 4K IP bearer network solution offers super large capacity platforms and a flat architecture, which lays the foundation for high network throughput. This solution provides fully-routed routers for improving end-to-end network throughput and leverages Layer 3 to the edge technology that allows CDN devices to move downstream. Users can then access nearby content, reducing end-to-end latency. Legacy Ethernet aggregation networks are prone to packet loss in circumstances of traffic congestion and bursts. To lower the impact of packet loss on throughput and to guarantee 4K service experience, Huawei routers have the capability to provide a large buffer.

High throughput requires end-to-end network guarantee. Huawei's innovative high throughput routers (HTRs) support real-time network congestion awareness, intelligent bandwidth prediction, and automatic throughput adjustment, greatly increasing end-to-end network throughput and decreasing the impact of packet loss and latency on video service quality. HTRs can increase throughput in the case of poor link quality in copper cable access or large attenuation of home Wi-Fi signals, effectively solving long loading time, pixilation, and stalling issues, thereby improving 4K service experience.

The sensitivity of the human eye in perceiving video, network uncertainties, and random errors place high requirements on 4K service O&M. Huawei's 4K O&M solution employs a video service engine to detect service quality deterioration and reports the service KQIs to a network management system (NMS) for service path restoration. The innovative IP FPM technology then implements fast, real-time fault identification. This 4K O&M solution effectively accelerates fault rectification and service restoration, guaranteeing user video experience.

At Global Analyst Summit, Huawei also released the NE40E-M2H. The NE40E-M2H has a forwarding capability as high as 480gbps and provides high-density 10GE and 100GE interfaces. Huawei Smart CO routers provide granular QoS capabilities, effectively guaranteeing video experience for high-value users. They also support virtual access technology, which virtualizes a CO router as a logic board on a BNG. This technology implements unified management of BNGs and CO routers, simplifying networks and improving O&M efficiency. The large-capacity CO router, BNG, and CR work together to construct an end-to-end high-throughput network, meeting carriers' demand for service growth for the next 5 to 10 years.

Huawei is continuously making technological innovation in the fixed broadband field, aiming to bring superior 4K experience to users as well as assist carriers in continuous network evolution and future-oriented cloud bearer technology to create greater value.
