In the multi-status network, data could be transmitted via different path. The network and its elements such as links and nodes are usually regarded with two statuses. However, in the real-life cases, due to the communication traffic jam and physical errors from network devices, it is a multi-state network. In order to discuss the reliability examination of such cases, this paper introduces an innovative algorithm to evaluate the reliability with continuous time intervals as constraints. Each source transmit a data sequence via a minimal path, where two paths have the same link. The time interval for generating the data and data volume obey random distribution. In this paper, Monte- Carlo simulation is used for getting the distributions. The time for transferring the data should be smaller than the constraints and such time is heavily related to the data volume. From the results, some lessons and insights could be learned. Firstly, under the random variables of data and time interval, their influences on the network reliability is great. Secondly, the end-users like network administrators can configure smaller data volume transfer and bigger time interval to achieve better network reliability.
