Abstract

In this extended abstract, we propose an SDN-based interdomain policy control methodology. Our main focus is on ASes built entirely on SDN architecture, but we will also provide methods for integrating ASes built fully on traditional packet forwarding devices. We seek to support the three basic AS relationships traditionally supported by BGP. They are (i) customer-provider: one AS pays another to forward traffic, (ii) peer-to-peer: both ASes mutually benefit from forwarding each others' packets, and (iii) redundancy: one AS uses another as backup in case of path failure.
