This work presentes Thor, a peer-to-peer distribution video system based on D1HT technique. The D1HT is a Distributed Hash Table that solves the lookups in just one hop with low maintenance cost of its tables updates. Using this technique, it was developed a layer called D1HThor, which is responsible for managing data segments that form the distributed video. This management is done to ensure that if any member of the network has a video, it will always be found by everyone else. Thor uses this layer to perform the search and distribution of videos. Experiments were performed with changes in bu er size and arrival rate at nodes. Results show that the application has a high scalability, ensuring a good quality of service.
