Abstract

The rapid advancement in cloud computing is leading to a promising future for shared data centers hosting diverse applications. These applications constitute a complex mix of workloads from multiple organizations. Some workloads require small predictable latency while others require large sustained throughput. Such shared data-centers are expected to provide potential service differentiation to client's individual flows. This paper addresses two important issues in shared data centers: bandwidth efficiency and service differentiation based on QoS (Quality of Service). We first evaluate the multipath-TCP (MPTCP) protocol over an OBS (Optical burst switching) network for improved bandwidth utilization in dense interconnect datacenter networks. We next present a simple and efficient 'QoS aware MPTCP over OBS' (QAMO) algorithm in datacenters. Our experimental results show that Multipath-TCP improves throughput over an OBS network while the QAMO algorithm achieves tangible service differentiation without impacting the throughput of the system.
