This model is based on the mechanism of virtual router, using multiple protocols extended BGP for the auto-discovery of VPN. MPLS is used as the forwarding mechanism and combined with DiffServ to support QoS of VPN.
该模型采用虚拟路由器技术，以MPLS为转发机制，通过多协议扩展的BGP协议来实现VPN信息的自动发现，并将DiffServ与MPLS技术相结合，从而有效地提供了QoS支持。
