In modern datacenters, variability of network load and performance tipically leads to unpredictable application performance for the many tenants sharing the hardware. To overcome this problem, Cloud providers should supply network guarantees as part of their Quality of Service (QoS) offer to the customers. This paper focuses on providing QoS guarantees for the network bandwidth. Starting form a Service Level Agreement (SLA) specification we model an admission control test and adopt an endpoint-only solution for the provider, enforcing bandwidth guarantees through the Linux Traffic Control (TC) technology. Experiments are reported to show the effectiveness of Linux TC in the proposed approach
