    • Apparatus, methods, and other embodiments associated with providing service insertion architecture (SIA) differentiated services in a virtual private network (VPN) environment are described. Embodiments may provision an authentication, authorization, and accounting (AAA) server with user-to-SIA service-context mapping information. With the AAA server provisioned, embodiments may acquire, in an IPSec VPN hub, during IPSec tunnel user authentication, from the AAA server, the user-to-SIA service-context mapping information. With the mapping information available, embodiments may dynamically map an SIA service to an IPSec VPN tunnel user based on the service information acquired from the Service Broker or Pseudo-Service Broker. The dynamic mapping facilitates providing differentiated services in the SIA by facilitating forwarding an IPSec packet received on the IPSec VPN tunnel from the user to a service node associated with the SIA service based, at least in part, on the IPSec SADB entry modified using the service information.
    • 描述了与在虚拟专用网络(VPN)环境中提供服务插入架构(SIA)差异化服务相关联的装置,方法和其他实施例。 实施例可以提供具有用户到SIA服务 - 上下文映射信息的认证,授权和计费(AAA)服务器。 在提供AAA服务器的情况下,实施例可以在IPSec VPN集线器中从AAA服务器获取用户到SIA服务上下文映射信息的IPSec隧道用户认证期间。 利用可用的映射信息,实施例可以基于从服务代理或伪服务代理获取的服务信息来动态地将SIA服务映射到IPSec VPN隧道用户。 动态映射有助于在SIA中提供差分服务,方法是至少部分地基于使用该服务修改的IPSec SADB条目,将在IPSec VPN隧道上接收的IPSec分组从用户转发到与SIA服务相关联的服务节点 信息。
