Measures, including methods, systems and computer program products, for use in processing route data in a network comprising a plurality of autonomous systems. At a network device, route data defining at least one route for network traffic which is configured on at least one border network device is received from the at least one border network device. The at least one border network device is located at a border of an autonomous system in the plurality of autonomous systems. The network device processes the received route data according to a set of policies to generate modified route data. The network device transmits at least a part of the modified route data to the at least one border network device. The at least part of the modified route data is operable to instruct the at least one border network device to modify the behavior of the at least one route.

Processing route data

Databases and methods for storing, processing and searching data in database tree structures are provided. More particularly, a method for processing data stored in database tree structures for use in data packet routing applications, and a method of searching a database containing data stored in a tree structure, using a search key, are provided. The tree structure includes a plurality of nodes. Data relating to a first node and a second node is stored in the database. The data includes a first node key and a second node key which is prefixed by the first node key. The tree structure is searched using a search key by traversing the second node and determining if the first node key has a prefix which matches the search key.
