# Towards Deterministic-Delay Data Delivery Using Multi-Criteria Routing over Satellite Networks
## 3 Problem Modeling
### Routing Algorithm
Additionally, this study introduces a VPN-based implementation scheme that leverages the flexibility and scalability of the SRv6 protocol, enabling efficient transmission of time-sensitive traffic within the existing network architecture without substantial modifications to the network infrastructure. This approach ensures high-reliability transmission of time-sensitive traffic and optimized resource utilization in satellite Internet environments, making it suitable for large-scale satellite network deployments. Overall, the proposed algorithm provides reliable technical support for real-world applications in large-scale satellite networks and demonstrates strong flexibility and applicability.
