Abstract

The present invention generally relates to methods of routing packets in a network comprising Autonomous Systems (ASs), next hop determiners for routing packets in such a network, systems for routing packets in such a network, and route indicator feeders for providing modified route indicators. A method of routing packets in such a network may comprise: obtaining route indicators each comprising: an indicator of a network prefix; and an indicator of an AS path for delivering packets to an AS having the network prefix; identifying at least one said route indicator having an AS path indicator comprising a predetermined AS identifier; storing the network prefix indicator of each said identified route indicator; receiving at least one packet having an address indicating a destination; and if the destination address of said packet is within an address range defined by a said stored prefix indicator, transmitting the packet on a non-peering connection to the AS having the predetermined AS identifier.
