During the 2023 MPLS SD & AI Net World Congress, Huawei's technology summit 
themed "Continuous Innovation in IP Domain, Boost New Growth" was successfully 
held at the Paris Exhibition Center in Paris. This summit discussed the target 
network architecture, protocol evolution, and automation technologies in the 
hope of helping carriers build converged IP networks to improve efficiency and 
introduced digital managed network solutions and architecture, which are 
intended to help carriers transform from ISPs to MSPs and drive new growth of 
B2B services. 

According to the industry development trend, Omdia senior analyst Sameer Malik 
pointed out that with the large-scale deployment of 5G and gigabit home 
broadband around the world and the acceleration of industry digital 
transformation, carriers' IP transport networks need to not only increase 
bandwidth, but also provide intelligent connections to transport multiple 
services with differentiated SLA assurance. This, together with network 
advantages, will allow carriers to expand B2B services.

In terms of the network architecture, Gu Rui, Vice President of Huawei Data 
Communication Product Line, elaborated on the future-oriented IP target network 
architecture. He explained that this architecture features ultra-broadband, 
full service transport, high automation, one-stop services, and green design. 
Technologies such as Wi-Fi 7, 800GE, and orthogonal architecture help build 
ultra-broadband infrastructure networks to meet requirements for ultimate user 
experience. An all-in-one hardware platform and network slicing meet the 
requirements of converged transport and provide differentiated SLA assurance. 
High automation is enabled based on SRv6 and network digital map. It provides 
one-stop services for B2B customers based on carriers' IP private lines with 
digital managed network. In addition, energy-saving and emission-reduction 
innovations at the equipment, network, and operational levels help build green 
IP networks and guarantee sustainable network development.

In terms of protocol evolution, Huawei's Chief IP Protocol Expert Robin Li said 
SRv6 is one of the best protocols for IP network evolution. SRv6 standards and 
technologies are becoming increasingly mature. More than 160 networks have been 
deployed with SRv6 globally, and deployments are ramping up. Carsten 
Rossenhövel, co-founder and CTO of the European Advanced Networking Test Center 
(EANTC), introduced the results of the SRv6 multi-vendor interoperability test 
in 2023. A total of eight mainstream vendors participated in the test, 
including Huawei. SRv6 test cases cover all scenarios, including basic routing 
protocols, SRv6 Policy, header compression, reliability, and OAM. In the past 
six years, more and more vendors have participated in SRv6 interoperability 
tests, and application scenarios have been fully verified.

In terms of automation, IETF Internet Architecture Board member Wu Qin said 
that the era of autonomous networks (ANs) has come. AN technologies are 
developing toward network programmability and openness, service 
definition-implementation decoupling, network digitalization, intelligent 
management, and other key directions. Telemetry-based network digital map 
provides network visualization from dimensions such as infrastructure, 
networks, slices, routes, services, and applications. It also enables 
configuration intent simulation verification and traffic optimization. This 
helps carriers better manage physical networks with digital capabilities.

For carriers' B2B services, Wen Huizhi, Chief Solution Architect of Huawei Data 
Communication Production Line, shed light on the architecture design and 
solutions for digital managed network services. Carriers need to design in five 
domains, including physical networks, user networks, O&M, security, and 
services, and provide NaaS capabilities to meet differentiated assurance, 
cross-domain collaboration, all-scenario protection, and tenant-level O&M 
requirements.

Finally, Zuo Meng, Vice President of Huawei's Data Communications Product Line, 
said Huawei is ready to work with carriers and industry partners to promote the 
evolution of target IP networks, build better converged ultra-broadband IP 
networks, explore new scenarios, services, and business models, and accelerate 
industry digital transformation, thereby helping customers achieve business 
success and drive new growth.
