摘要
This article is devoted to enhancing the mathematical models for traffic engineering routing and load balancing to ensure differentiated quality of service for packet flows with varying priorities in communication networks. The research focuses on formulating updated load-balancing conditions considering packet-flow priorities and conducting a comparative analysis of different models to identify the most effective solution. The study introduces a multipath routing model based on the type of service and presents numerical research to evaluate the proposed solutions in varying network conditions. The findings allowed us to select the model that offers the most precise regulation of service differentiation for different priority flows by optimizing the load-balancing strategy. This model directs higher-priority packet flows through less heavily loaded links and routes, while lower-priority flows are sent through more heavily loaded paths. Moreover, the routes for higher-priority flows are designed to have fewer hops than those for lower-priority flows. This approach improves network resource utilization and simplifies the architecture for delivering differentiated quality of service, potentially reducing the need for the manual configuration of congestion management mechanisms. The study concludes that the proposed enhanced model is the most effective for practical implementation in modern networks, offering a robust solution for managing diverse priority traffic.
