Abstract

Information about virtual private networks—VPNs—in each domain of a multi-domain communications system is provided. By comparing a request for a configuration of a VPN with the provided information of other connected domains, a match can be found. VPN configuration can then be performed based on the outcome of the match. The provided domain VPN information is in one embodiment spread to other domains under constrictions put by SLAs between domain operators. The spreading of VPN information can be performed regularly or triggered by an external event. In another embodiment, the VPN configuration request is instead spread to different domains.
