CustRouting: Trusted and Customized Routing in Integrated Heterogeneous Networks

The next-generation network intends to integrate different types of networks, including IP networks and mobile cellular networks, to form an integrated heterogeneous network (Inte-HetNet). Routing in the Inte-HetNet requires the collaboration of different types of networks and considers user routing preferences. However, existing work focuses on a specific type of network without considering various user requirements, resulting in poor user experience, bad network performance, and low data transmission efficiency. To this end, we propose CustRouting, a customized cross-domain routing method in Inte-HeNet that considers user requirements. Concretely, we weight different user requirements to provide customized routing services to users accordingly. Meanwhile, we employ Border Gateway Protocol (BGP) and Segment Routing (SR) to realize inter-domain routing and end-to-end data transmission. We evaluate the performance of CustRouting and demonstrate its advantages in terms of trustworthiness and customization by comparing it with existing work.
