Multicast has brought a drastic change in the field of networking by offering bandwidth effective technology that leads to reduce tariff.It is popular for optimizing network performances.This paper evaluated a model for fine tuning the value of a k in a K-fold multicast network under different traffic loads under poisson traffic with finite queue at each node.Stationary distribution has been derived for the network states and various expressions have been developed for the network to determine throughput and the blocking probability of the network.It has been established from this research work that by increasing the fold number, the network throughput can be increased very fast.However, it has been also observed that after increasing the fold number up to a certain value, the blocking probability stops to increase and becomes constant.We have also noticed that the throughput increases with the increase of the offered traffic and the blocking probability decreases when the system parameter k is increased.Moreover, an optimum value of k ceases the blocking probability for a particular value of the offered traffic for finetuning the outcome of the network.
