Two versions of Baget, the Russian real-time operating system (RTOS), are presented in this paper. It provides some elements of history that led to the development of the initial versions, and then the fork to two separate tracks. It compares from a rather high-level perspective the two versions in terms of support of standards, scheduling algorithms (standard ones), tracing mechanisms, error handling, time management, and portability.

Although the subject is interesting and the work certainly worth some dissemination, I’m not convinced by the depth of the paper. The descriptions and comparisons are rather superficial; there is no state-of-the-art section that would allow a meaningful comparison with other similar systems. For instance, some latency figures are provided in the time management section, but they are simply presented, without any discussion, either to compare the two versions of the OS or to compare with other RTOSs.

The paper leaves me with a “not enough” feeling, having learned very superficially about the Baget RTOS, but not enough to get a real idea of what it is about, how it is built, what it is used for, and so on. It would certainly help to present it in a much broader perspective, showing how different it is compared to other systems, what makes its design unique, how its performance compares, and so on.
