These models are limited to FCFS, Poisson failure and exponential service times, similar to METRIC--based models.
Table 2 General Queuing Network Models Source Queuing Environment Description Jackson  Poisson arrival, Under the product--form exponential service structure, the system is times, multi--stages, solved by analyzing each FCFS, open queuing node separately and then network, exact analysis the results are combined.

It is observed that the performance of bi-directional paths are better in case of mixed nature of machine sequence and its performance is found to be better for FCFS
These four policies are the FCFS

Making this argument, the presentation does not state anywhere that, in effect, FCFS
was announced for the allocation of spectrum for basic service operators or fixed line companies in 2001.
The one- man panel said Shourie did not notify the FCFS
basis for allocating spectrum during his tenure.

Prior to January 7, 2008, the date of receipt of application in DoT was reckoned for the purpose of FCFS
and after January 7, 2008, the date of compliance of LoI ( letter of intent) was reckoned for the purposes of FCFS
