Abstract: A method includes receiving, at a media device, a video game from a server via a network. The method includes installing, via the media device, the video game to a storage device associated with the media device. The method includes receiving, at the media device, a request to play the video game. The method includes sending an authorization request to the server from the media device via the network in response to the request. The method includes receiving authorization to execute the video game at the media device. The authorization is based on an identifier of the media device included in the authorization request being associated with rights allowing execution of the video game. The method also includes executing the video game via the media device in response to receiving the authorization.

Abstract: A method for routing data in a network including a plurality of nodes connected by links, the method includes collapsing first and second rings of the nodes together, for each of the nodes in the network, determining a shortest path tree to each of the other nodes in the network, and for data sourced from a particular one of the nodes in the network, blocking the link or links not included in the shortest path tree determined for the particular one of the nodes. Also, a system for routing data through a network having a plurality of nodes connected by links, includes a ring collapsing module for collapsing first and second rings of the nodes together, a shortest path tree calculation module for determining, for each of the nodes, a shortest path tree to each of the other nodes in the network, and a link blocking module for blocking the link or links not included in the shortest path tree determined for data sourced from a particular one of the nodes.
