CSFQ is designed as an open loop controller to provide fair best effort service, which supervises the bandwidth consumption of pre-flow and has become helpless after P2P flows dominate the traffic of the Internet. Token- Based Congestion Control (TBCC) is based on a closed loop congestion control principle, which restricts the token resource consumed by an end-user and provides fair services with O(1) complexity. As Self-Verifying CSFQ, it is heavy load to police inter-domain traffic for lack of trust. In this paper, Token- Limited Congestion Control (TLCC) is presented, which appends inter-domain congestion control to TBCC. TLCC provides the fixed cost to the inter-domain congestion charging with O(1) complexity. By simulations, it is demonstrated that TLCC can provide stable and fair bandwidth allocation across the domain border.
