| Abstract: |
BGP, the only inter-domain routing protocol used today, often converges slowly upon outages. While fast-reroute solutions exist, they can only protect from local outages, not remote ones
(e.g., a failure in a transit network). To address this problem, we proposed SWIFT, a fast-reroute framework enabling BGP routers to locally restore connectivity upon remote outages by combining
fast inference mechanisms in the control-plane with fast data plane updates. While SWIFT is deployable on a per-router basis, we show in this demonstration that we can deploy SWIFT in
Software-Defined Internet Exchange Points (SDXes) with a simple software update. We show that "SWIFTing" an SDX is highly beneficial as it enables to converge the entire fabric within few seconds
instead of the tens of seconds required by the original software. |
