Practical and Application of Segment Routing over IPv6 in Cross-Domain Computing Force Network

As China's "East Data, West Computing" project advances, Communication operator's networks face significant challenges in cross-domain computing force network services, including delayed cross-domain network performance awareness, inefficient cross-domain service provisioning, and difficulties in cross-domain path computation and optimization.Based on the operational realities of China Mobile's data-bearing network, this paper proposes an operational solution for cross-domain computing force network services by leveraging advanced technologies such as SRv6 and SDN. The solution establishes a two-level controller architecture, deploys real-time network quality sensing technology, and develops end-to-end globally optimal path computation capabilities. This achieves highly efficient cross-domain service provisioning and flexible differentiated service capabilities.The implementation successfully manages and controls over 10,000 routers, achieves network quality measurement precision of 0.01 us with second-level real-time reporting, enables optimal end-to-end SRv6 service paths across domains with minute-level provisioning, and delivers significant end-to-end latency optimization for cross-domain services.
