Estimating the term…
The present application generally relates to a system and method for interfacing a source-selected path routing network with existing legacy IP networks. This interfacing may be achieved by installing specific router devices at the borders of the source-selected path routing network. Said router devices are able to exchange routing information in the form of IP prefix announcements and withdrawals between legacy IP networks and the source-selected path routing network according to an appropriate exterior gateway protocol. Hereby, the source-selected path routing network that in reality comprises a plurality of autonomous systems is conceptually regarded as a single autonomous system. Hence, a legacy IP network that is a direct neighbor of a source-selected path routing network may ensure that traffic destined to it traverses the source-selected path routing network by announcing its routing information only to the source-selected path routing network via an appropriate exterior gateway protocol.
A method for routing and forwarding data packets to a legacy IP network through a source-selected path routing network comprising a plurality of autonomous systems, ASes, wherein data packets are transmitted from a node A1 of the legacy IP network A to a node B1 of a legacy IP network B, wherein the method comprises the steps of:
A router device for use inside an autonomous system (AS) of a source-selected path routing network capable of interfacing the source-selected path routing network comprising a plurality of autonomous systems, ASes, with neighboring legacy IP networks, the router device configured to:
A non-transitory computer-readable medium storing instructions that when executed by a processor or processors cause a device or devices to perform operations, the operations comprising:
