N2 - We introduce TeaVisor that provides bandwidth isolation guarantee for network virtualization (NV) based on software-defined networking (SDN). SDN-based NV (SDN-NV) offers many benefits to clouds, such as topology and address virtualization while allowing flexible resource provisioning, control, and monitoring on virtual networks. In SDN-NV, however, routing is done by tenants independently; thus, existing studies have difficulties in bandwidth isolation guarantee due to the overloaded link problem. Bandwidth isolation guarantee is essential for providing stable and reliable throughput on network services in SDN-NV. Without bandwidth isolation guarantee, tenants suffer degraded service qualities and significant loss in revenue. To address this problem, we design and implement TeaVisor in three components: path virtualization, bandwidth reservation, and path establishment. Through extensive experiments, TeaVisor shows that bandwidth isolation is guaranteed with near-zero errors, which is three orders of magnitude better than existing studies. In addition, TeaVisor guarantees the minimum and maximum bandwidth at the same time. We also present an overhead analysis of TeaVisor in control traffic and memory consumption.
