Comments on `A note on the performance of ENET II´ by P. Gburzynski and P. Rudnicki

The original authors (see ibid., vol.7, no.3, p.424 (1989)) describe some results from a simulation study of ENET II and Ethernet. ENET II is a method, proposed by the commenter (Comput. Networks ISDN Syst., vol.9, no.3, p.209-14, Mar. 1985), to implement several variants of well-known collisions-resolution protocols in an asynchronous environment in a manner upwardly compatible with Ethernet. The original authors concluded that the ENET II protocol is inferior to the standard Ethernet. The commenter compares the assumptions in the simulation whose results were expressed in the original paper to their assumptions and makes several points about the analysis they described. The thrust of the comment is not to negate the results but to make the reader aware of the subtle differences in the representation of the results that make it difficult to conclude that ENET II is either inferior or superior to Ethernet
