Method, system and device for maintaining routes

A method, system, and device for maintaining routes are provided. A communications network includes multiple point of presence (PoP) groups, where each of the PoP groups includes one or more PoP nodes. PoP nodes within the same PoP group issue routing information of the same super prefix. PoP nodes within different PoP groups issue routing information of different super prefixes. The method further includes the following steps. A PoP node acquires routing information of a detailed prefix covered by a super prefix issued by the PoP node and synchronizes the routing information of the detailed prefix with other PoP nodes within the same PoP group. The method, system, and device reduce flow of data forwarded by each PoP node.

Smart road-toll-system

A road pricing smart client and method for a road pricing system enabling the removal of information from the positioning data describing the itinerary which suggest private data such as travelling speed and itinerary of the originator of the data. Accordingly, the smart client and method is configured to re-sample the original positioning points of the route into equidistant sections, remove timing information from the positioning data, slice the re-sampled route into slices shaped as those provided by other road users by employing a common “virtual grid”. By transmitting the slices in randomized order with an arbitrary delay, coherence of slices corresponding to formerly neighboring portions of the itinerary, are not correlated anymore. However, there is still enough information provided to the toll system to send an excerpt of the fee database allowing the smart pricing client or method to calculate the occurred fees.The main advantage of the smart client and method is that it delegates in a secure and privacy-preserving way the costly operations to the external toll server proxy. Thus, storage of digital maps in the client is not required, and tariff updates are only transmitted when necessary in a way that preserves privacy. Finally the data transmitted by the smart client can be preprocessed and compressed in order to remove all unnecessary personal information, thereby reducing the bandwidth requirements on the telecommunication network. Further, the proposed solution enables to raise statistics on road usage, i.e. traffic appearance by road-section without endangering privacy of the individual road users.
