Abstract

This invention has two mechanisms: Dynamic AS switching for AS confederations (Fig. 1) and Dynamic AS switching. The Dynamic AS switching for AS confederation mechanism provides a mechanism for an Autonomous System (AS 10) within an AS confederation to survive disconnection from the rest of the Autonomous Systems within the AS confederation (AS 10). This invention provides a mechanism for the AS within the AS confederation to use a pre-agreed upon fail-over to the internal AS, so its eBGP connections will not be reset. The Dynamic AS switching mechanisms allows to peers to re-negotiate AS number changes in any Autonomous Systems the peer represent without dropping the BGP peering session.
