Abstract: The IEEE Audio Video Bridging (AVB) Task Group (TG) was created to provideEthernet with soft real-time guarantees. Later on, the TG was renamed toTime-Sensitive Networking (TSN) and its scope broadened to support hardreal-time and critical applications. The Stream Reservation Protocol (SRP) is akey work of the TGs as it allows reserving resources in the network,guaranteeing the required quality of service (QoS). AVB s SRP is based on adistributed architecture, while TSN s is based on centralized ones. Thedistributed version of SRP is supported and used in TSN. Nevertheless, it wasnot designed to provide properties that are important for criticalapplications. Therefore, we propose a new version of SRP with enhanced servicescalled Consistent Stream Reservation Protocol (CSRP). In this document wedescribe the SRP and CSRP UPPAAL models we developed and the queries we used toverify their termination and consistency properties.
