| 20100189110 | Multipath data communication - A multipath data communication network structure in which probing middle-boxes send periodical probe messages through their different interfaces and subsequent routers map the probe messages through their randomly selected interfaces until each probe message arrives at a destination, engages to a loop or meets a time-to-live limit. The probing middle boxes select a random interface for each probe message and furnish their routable identification and a temporary random number correlated to the selected interface to each probe messages. Subsequent multipath routers select a random outgoing interface and random forwarding state descriptor (FSD) and temporarily correlate the selected random outgoing interface with the FSD and add the FSD to the probe message. The probe messages provide different destinations with various hidden paths. Each hidden path enables forwarding of packets from probing middle-boxes to the destination without identifying any routable address en-route to the destination. The destination then provides a data source with the hidden path. Each multipath network element only store their mappings related to the paths for limited term so that each path expires and vanishes after the term. Attackers are not issued a new path and thus denial of service attacks are shortly stopped. | 07-29-2010 |
| 20100328528 | TRANSMISSION CAPACITY PROBING USING ADAPTIVE REDUNDANCY ADJUSTMENT - In accordance with an example embodiment of the present invention, there is provided an apparatus configured to instruct a redundancy encoder to increase a level of redundancy of a media stream, an error rate determination to determine an error rate of a communication path conveying the media stream with increased redundancy, a comparator configured to compare a bandwidth used to convey the encoded media stream at the increased redundancy level with a bandwidth for conveying the encoded media stream at a second quality level greater than the first quality level, the apparatus being further configured to provide a switching signal to a media encoder to start encoding the media stream at the second quality level responsive to the used bandwidth being sufficient for conveying the media stream encoded at the second quality level and the determined error rate being less than a predetermined threshold value. | 12-30-2010 |
| 20100329248 | Multi-path transport - A method including operating in an apparatus a multi-point multi-path transport protocol providing a multi-point multi-path transport connection, and using said apparatus in said multi-point multi-path transport connection as a part of an end system formed by said apparatus and other apparatuses that are physically distinct from said apparatus. | 12-30-2010 |
