Inbound Traffic Load Balancing in BGP Multi-homed Stub Networks

Abstract

Multihoming load balancing improves network performance by leveraging the traffic among the access links in a multi-homed network. Currently, no effective load balancing system is available to handle the inbound traffic in a BGP multi-homed stub network, where the traffic volume is unknown to the network and the route of the traffic is hard to control. In this paper, we propose ILBO, an inbound traffic load balancing mechanism to effectively balance the inbound traffic in a BGP multi-homed stub network. ILBO predicts and schedules the inbound traffic based on outbound traffic. It also provides an inbound traffic control scheme that can guarantee the successful execution of the traffic scheduling.
