  The IEEE Audio Video Bridging (AVB) Task Group (TG) was created to provide
Ethernet with soft real-time guarantees. Later on, the TG was renamed to
Time-Sensitive Networking (TSN) and its scope broadened to support hard
real-time and critical applications. The Stream Reservation Protocol (SRP) is a
key 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 a
distributed architecture, while TSN's is based on centralized ones. The
distributed version of SRP is supported and used in TSN. Nevertheless, it was
not designed to provide properties that are important for critical
applications. Therefore, we propose a new version of SRP with enhanced services
called Consistent Stream Reservation Protocol (CSRP). In this document we
describe the SRP and CSRP UPPAAL models we developed and the queries we used to
verify their termination and consistency properties.
