Obm - an Optimal Bandwidth Management Strategy to Virtual Machines in Cloud Environment Using Predictive Analytics

Network bandwidth is a key resource in cloud computing. Its inefficient allocation still poses issues in a virtualized cloud environment. Efficient and dynamic resource allocation is essential to fulfill Quality of Service (QoS). In this paper, we propose an optimized dynamic bandwidth allocation strategy based on SLA and previous traffic statistics. The algorithm uses previous traffic statistics to predict future bandwidth requirement for every virtual machine. Optimized Bandwidth Manager (OBM) allocates this predicted bandwidth to virtual machine by applying readjusted bandwidth limits directly to the Virtual Network Interfaces.
