The paper presents an approach to dimension Circuit Switched networks and find the relationship between the parameters of the Circuit Switched networks on the condition of specific probability of call blocking. Our work is creating a Simulation code based on Erlang (B) formula to draw graphs which show two curves for each graph; one of simulation and the other of calculated. These curves represent...
This paper presents a series of labs in where the performance of practical WLAN technology is evaluated by using PCATTCP software. The experiments can be summarized as follows: Measurement of the throughput as a function of the number of users and network configuration, offered load (sharing efficiency/ fairness). Comparison between the throughput of TCP protocol, and the throughput of UDP Protocol...
