20080276091 | Mobile Device File Sharing Method and Apparatus - File sharing between mobile devices is enabled using a hierarchical Distributed Hash Table (DHT) based message routing system. According to one embodiment, mobile device electronic content is shared via an overlay network of computer nodes arranged according to a hierarchical DHT by a mobile device generating a message. The message includes a key configured to identify mobile device electronic content and to enable routing of the message based on the hierarchical DHT through the overlay network upon reception of the message at any of the computer nodes. The message is transmitted to a packet-switched radio access network, the packet-switched radio access network configured to send the message to one or more of the computer nodes. The message is eventually routed to the computer node responsible for the key. The responsible computer node processes the message, e.g., by registering electronic content, deregistering electronic content or responding to an electronic content request. | 11-06-2008 |
20100061385 | METHOD AND SYSTEM FOR PROVIDING A ROUTING ARCHITECTURE FOR OVERLAY NETWORKS - A link state overlay routing protocol that is capable of routing based on flat identifiers is proposed. The very fundamental problem that exists with 5 routing based on flat identifiers is that the identifier space can not be aggregated. All existing routing is based on hierarchy and aggregations of IP-addresses to network addresses, so called subnetting. The proposed routing protocol is capable of deciding the best path to a destination taking into account different possible parameters (e.g., round trip time). The scalability of the 10 protocol is solved by not taking decisions based upon a single end-node identifier; instead the routing decisions are taken based on a network identifier. | 03-11-2010 |

If it is determined, based on the traffic load, that not all available paths are needed:—Selecting at least one path that should not be used to carry traffic,—Rerouting any traffic using the selected at least one path to at least one alternative path, and —Placing any network elements or links not carrying traffic after the rerouting in standby mode in which the power consumption of the elements is reduced, to reduce the power consumption in the network. | 03-29-2012 |
20120102228 | INTER-DOMAIN ADVERTISEMENTS IN MULTI-DOMAIN NETWORKS - In a multi-domain network each domain, or Autonomous System (AS), has a route calculation entity (PCE A) which is responsible for computing paths between domains on behalf of clients. The route calculation entity (PCE A) sends advertisement messages to a route calculation entity (PCE B) in another domain. The advertisement message carries at least one of: inter-domain resource information and aggregated intra-domain information, such as simplified topology information or cumulative traffic engineering (TE) metrics. The inter-domain resource information can be inter-domain route or reachability information which is normally discarded by a routing protocol such as the Border Gateway Protocol (BGP) and can include inter-domain Traffic Engineering (TE) information such as reservable bandwidth. | 04-26-2012 |

Upon determining that a node is common to first and second DHT rings on the same hierarchical level and having at least one Overlay Router in common, a link is started between a node in the first DHT ring and a node in the second DHT ring by establishing an indirect link through the common node. An indirect link is created between the first and second DHT rings, and virtual links are created to DHT rings positioned higher in the DHT ring hierarchy until all the DHT rings are merged into a single logical ring. | 11-29-2012 |

20130315257 | ENERGY EFFICIENT ROUTING AND SWITCHING - This invention relates to a method and a node for energy efficient routing and switching in a communication network. When determining the best path from an originating node to a destination node, current routing or switching protocols use route selection metrics based on the bandwidth of the link interface. Certain paths are however consuming more power that others which can result in traffic flowing over a high power consuming and long distance path, because this is the best path based on the existing metrics. The present invention overcomes this by introducing a node and a method to switch data also using energy consumption metrics. These metrics can be based on the power consumption in link interfaces, the links and in the node. | 11-28-2013 |
