In the Discrete-Event System Specification (DEVS) time variables are Real numbers. This is common to other simulation formalisms for Discrete-Event Simulation (DES). Current simulators for these formalisms approximate time variables using floating-point or rational representations. Neither of them is capable to adequately represent irrational numbers. The(More)
BitTorrent is a fast, popular, P2P filesharing application with no search engine mapping keywords to contents. The trackerless approach uses a DHT based on Kademlia to look for sources when the SHA1 hash of the metadata of the content to transfer is known. However, this DHT implementation is exposed to several identified security issues. On the other hand,(More)
The basis of this paper is grounded upon the theoretical assumption, which states that the integration of BitTorrent with Software-defined Networks (SDNs) will degrade the performance of BitTorrent, instead of improving it. This was further evaluated by emulating this experiment on a Ring topology to verify the results. The experimental results, however,(More)
