ZTE and China Telecom Guangdong advance cross‑vendor IP network simulation pilots, paving the way for intelligent network operations

ZTE announced that China Telecom Guangdong has officially released the ESurfing Simulation 2.0 - CrossVendor IP Network Simulation Standard at the Talent & Expertise Development Forum (Peizhi Talent Empowerment Initiative) hosted by the company. Built on the joint simulation system co-developed by ZTE and China Telecom Guangdong, the standard applies digital twin technology to form a closedloop workflow from change submission through simulation verification to implementation authorization. This marks a pivotal shift of network O&M from experiencereliant manual work to systematic preverification. The solution has become a replicable benchmark for multivendor collaborative simulation in the telecommunications industry, serving as a milestone to accelerate the rollout of intelligent network operations across the sector. Achieving HighPrecision Network Simulation to Strengthen Predictive O&M Capabilities The system adopts advanced network mirroring technology and proprietary protocol simulation algorithms, overcoming the traditional bottleneck of resourceintensive dynamic modeling. It achieves over 95% digital twin fidelity for device status and routing protocols. O&M staff can accurately evaluate the impact of network adjustments in advance, enhancing the safety and precision of network operations. Breaking MultiVendor Simulation Barriers to Build an Efficient O&M Model As communication networks keep expanding and evolving into more complex architectures, crossvendor O&M faces prominent challenges including low modeling efficiency, difficult collaboration and excessive resource consumption. ZTE and China Telecom Guangdong have innovated a distributed crossvendor simulation architecture following the principle of vendorspecific simulation, unified collaboration. A global coordinator works seamlessly with dedicated simulation systems from different vendors to eliminate device simulation barriers, effectively reduce development and maintenance costs and enhance system scalability. Remarkable Pilot Results Enable ZeroError Network Changes Prior to the standard release, China Telecom Guangdong and ZTE completed phased pilot deployments from single-vendor to multi-vendor scenarios in Foshan and Yangjiang. The pilots covered all devices on the new metropolitan area networks of the two cities, targeting four core scenarios: protocol parameter modification, new home broadband service cutover, new device commissioning and network transformation. The solution covers more than 90% of mainstream network change scenarios. Field tests prove that presimulation verification can substantially lower network change risks and realize zeroerror operations, laying a solid foundation for largescale nationwide promotion. Looking ahead, ZTE and China Telecom Guangdong will further upgrade system functions, expand application scenarios and iterate the standard to solidify the ecosystem of crossvendor intelligent O&M. Leveraging technological collaboration, ZTE will build the HIIPNet high-performance and high-intelligence IP network core platform, driving the IP network to evolve from manual O&M to intelligent scheduling and global crossnetwork coordination. Committed to openness and continuous innovation, ZTE will partner with global industry players to advance the automation and intelligence of telecommunication networks, empowering the highquality development of the digital economy.
