Huawei’s Hank Chen: Build a smart cloud network, enabling growth of all services


[Dubai, UAE, October 20, 2021] At the Ultra-Broadband Forum (UBBF) 2021, Hank Chen, president of the router business of Huawei’s data communications product line, delivered a keynote at the Intelligent Cloud-Network session titled “Build Intelligent Cloud -Network, Enabling All-Service Growth. ” He pointed out that Huawei’s smart cloud network solution can help operators create future-oriented target networks, adapt to changes in diverse services, unleash the potential of traditional services, seize new opportunities B2B and, ultimately, to enable the growth of all services.

Services to consumers and the vertical industry are diversifying. For individuals, the user experience is constantly improving, with short videos, social apps, live streaming, and AR / VR growing in popularity. For homes, they are moving from places of entertainment to places of work and education, as the volume of traffic and the number of subscribers continues to increase. For businesses, more and more services are clouding at an astonishing rate. All of these diverse services provide huge opportunities for operators – B2C and B2H services are the cornerstone of an operator’s stable revenue, and B2B service is the biggest and most important opportunity.

Operators mainly face two waves of service development challenges: The first wave is that consumer services are moving from a connection orientation to an experience orientation. This involves three specific challenges. First, the multiservice aggregation point (the central office) becomes a bottleneck due to a lack of space as the downward DC movement to the edge gains popularity. Second, the traffic and its directions become more and more uncertain, but the networks lack intelligent planning capacity, resulting in low network utilization. Finally, traditional IP networks operate in shared and best-effort forwarding modes, which are difficult to ensure user experience once congestion occurs. The second wave is that more businesses need multi-cloud connection capabilities for their digital services. However, network and cloud capabilities don’t match well. Challenges such as slow network service provisioning and lack of tenant assurance are present.

To meet these challenges and fuel the growth of all services, Chen believed that a forward-looking target IP network should have the following four characteristics:

  • First of all, all services in one network. This network must be able to support all B2C, B2H, B2B services.
  • Second, network programmability. This network must be able to flexibly plan the routing paths between clouds and SRv6-based networks to optimize network utilization.
  • Third, deterministic experience. This network must be able to provide guaranteed bandwidth and latency at the tenant level, replacing traditional transmission at best.
  • Last, agile cloud connection. This network must support a flexible multi-cloud connection for rapid provisioning of services.

Huawei’s smart cloud network solution is specially designed for operators to build such a future-oriented target IP network. This solution provides five key functionalities to enable the growth of all carrier services.

  1. All-service super edge CO, allowing all-service rolling. Huawei’s super edge compact CO can support diversified services, greatly reducing the total cost of ownership and improving the service experience. Specifically, Huawei’s super edge CO router adopts all-in-one design. It integrates ARM, CGN, IPsec and Service Router (SR) functions into a single box-shaped device, saving 60% space and reducing power consumption by 70%.
  2. SRv6-based network programmability for flexible cloud network planning: Huawei’s intelligent cloud network solution supports flexible scheduling of network paths and orchestration of services, as well as on-demand traffic planning, optimizing the utilization of the entire network. SRv6-based service chaining allows VAS to be flexibly orchestrated and subscribed to on demand. At present, SRv6 has been put into large-scale commercial use.
  3. Elastic slicing for a differentiated service assurance: Innovative technologies are used to make slices exploitable, productive and monetizable, helping operators to increase their revenues and optimize return on investment. According to Chen, Huawei has achieved the following slicing innovations: Hierarchical slicing upgrades the original one-dimensional slicing to two-dimensional, enabling precise service assurance and doubling the capacity for monetization. Elastic slicing enables dynamic capacity expansion without loss and on-demand adjustment without impacting services or wasting resources.
  4. One-hop connection to multiple clouds for flexible multi-cloud connection and scheduling: The multi-cloud backbone can pre-connect the resources of multiple cloud providers. Businesses only need to negotiate services with one operator. Services can be quickly migrated to the cloud and flexibly scheduled based on SRv6, and service paths can be flexibly selected based on latency and bandwidth to ensure the service experience. Huawei’s unique intelligent cloud map algorithm enables operators to intelligently and uniformly plan multi-cloud resources, improving cloud resource utilization by 30%.
  5. Network as a Service (NaaS) for an e-commerce type service experience: The cloud-to-network integration architecture delivers an e-commerce-like service experience. This involves three steps: At the pre-sale stage for the service subscription, an optimal cloud access position and latency-based path selection capabilities are provided. At the sales stage, services can be quickly commissioned with a visualized network-wide status. At the after-sales stage, tenant-level self-services are provided, allowing operators to query private line SLAs anytime, anywhere. In addition, Huawei greatly simplifies the number of interfaces north from 1000 to 100 and reduces the integration time by 90% with modular interfaces. Services can be provisioned in minutes, bandwidth can be adjusted on demand, and orders, SLAs and faults can be viewed from multiple dimensions.

To date, the key capabilities of the smart cloud network solution have been deployed to more than 100 networks across the world, including operators and verticals, such as smart healthcare, smart education, smart government and smart manufacturing. Huawei will continue to cooperate with operators and partners to accelerate the innovation and deployment of intelligent cloud network solution and promote the evolution of IP networks.

Chen believes that intelligent cloud network solution is the foundation of DICT transformation and can help operators achieve growth of all services. For B2C services, this will help build ultra-broadband, automated and intelligent networks and promote long-term evolution. For B2H services, this will accelerate network monetization and increase ARPU through assurance of experience and fine-tuned operation. For B2B services, it will provide differentiated cloud network capabilities to help operators drive the development of digitization.

“IP On Everything will be the future,” Chen said. “IP connectivity will continue to expand, continuously bringing intelligence and computing power to every person, every home and every industry for a fully connected and intelligent world. “
