|Title||An Approach for Bandwidth Guarantee in Multi-tenant Cloud Datacenter Network|
The rapid development in cloud infrastructure allows cloud providers to offer computing power such as CPU, memory and storage to different customers, and serve multiple tenants at the same time. Unfortunately, due to network nature, cloud provider give no guarantee of network resource allocation to individual VM, relying on the fact that VMs are unlikely to simultaneously maximize their use of their nominally assigned bandwidth. However, many research shows that there is potential for VM to effect each other due to contention on network resource, or as side effect of noisy neighbor, and varying of bandwidth demand across time. Resulting in a severe lack of predictability and fairness of application performances. That cost tenants unpredictable cost and provider loss revenue. Running cloud application without deprecation of performance require cloud provider to offer both computation power and network resource as bundle. The new approach that combine both computing and network resource in one form called virtual data center (VDC), formally known as VDC embedding problem. In this approach, cloud provider should provide tenants with an interface to explicit specifying their bandwidth demand. Cloud provider achieve deterministic bandwidth guarantee by proper placement of tenant VMs and static enforcement of rate limit. However, offering such service to customer is not easy task, and many researchers classify this problem as multiple dimension ben packing problem, which been as NP hard problem.
