Campus networks and enterprise networks increasingly depend on middleboxes (e.g., firewalls, NAT, load balancers, IDS/IDP) to provide essential services or enforce network policies. These middleboxes often limit the performance of network applications, especially those involved in big data transfer. To address this problem, we propose a Software Defined Networking (SDN) campus network architecture, called VIP Lanes, that provides the ability for pre-authorized, trusted users to create flows that bypass middleboxes, thereby enabling those users to achieve substantially better performance while maintaining security and policy compliance for other network traffic. In this paper, we present the VIP Lanes abstraction and describe an authorization and policy-enforcement service used to establish trusted VIP Lanes. We describe an initial prototype implementation that not only demonstrates the viability of the VIP Lanes approach, but also gives an indication of the types of performance improvements that are possible - in some cases approaching a two order of magnitude reduction in transmission times.
