Assessing response routes in a network

摘要

Method and system are provided for assessing response routes in a network of connected nodes wherein a querying node propagates a query through multiple routes of intermediate nodes to a data source node and the data source node returns data to the querying node. The method at a data source node includes: receiving a query instance including metadata with route information of the route of intermediate nodes in the network that the query instance has travelled through from a querying node to the data source node; comparing the route information to a route policy, e.g. whether the intermediate nodes are trusted; and responding to a query instance which meets the route policy by returning the query response via the route of intermediate nodes of the query instance.
