20090122724 | Peer-to-Peer Network including Routing Protocol Enhancement - Methods, apparatuses and systems that enhance the operation of peer-to-peer networks with routing protocols. In a particular implementation, peer nodes of a peer-to-peer network use an enterprise routing protocol to construct p2p network routing tables that support identification of peer nodes implementing a distributed hash table. This allows each peer node on the p2p network to know about every other node, and to learn, within IP network routing convergence times, of the arrival, departure, and failure of peer nodes in the p2p network. It also allows for single hop queries to other peer nodes. | 2009-05-14 |
20090122725 | ROBUST NETWORKS FOR NON-DISRUPTIVELY DISCONNECTING PERIPHERAL DEVICES - A network and method for non-disruptively disconnecting communication devices are disclosed. The network includes a primary network unit including a first logical layer, and a plurality of secondary network units. Each secondary network unit of the plurality of secondary network units includes the first logical layer, a second logical layer, and a connector arranged at a junction of the first logical layer and the second logical layer. The network also includes a plurality of electrically conductive links, wherein an electrically conductive link of the plurality of electrically conductive links is connected to the first logical layer of a first network unit at a first end, and to the first logical layer of a second network unit at a second end. | 2009-05-14 |
