In this paper, the authors propose a SDN based disaster-aware smart routing scheme for highly-available information storage systems. The authors' proposed scheme is based on the concept of Symbiotic Computing to recognize disaster status in Real Space, and provides appropriate routes form Digital Space dynamically. This realizes effective data transmission considering disaster situation and its time variation. In this paper, the authors design and implement their proposed scheme with dynamic multipath routing and parallel data transmission to enhance the network performance. They also evaluate its effectiveness through large-scale network environments.

How to test the communication robustness of high-bandwidth and low-latency network under harsh environments is critical for evaluating reliability of network. The accuracy of data transmitted by large-scale network control software under busy communication is fully verified in the paper, by means of the simulation to simulate uncertainty time and link failure phenomenon of data transmission occurs in the real application environment to complete the test of robustness for the large-scale network control software, which is useful for assessing the reliability of the network.

Large Scale Tests

Network performance is key to the correct operation of any modern data centre infrastructure or data acquisition (DAQ) system. Hence, it is crucial to ensure the devices employed in the network are carefully selected to meet the required needs. Specialized commercial testers implement standardized tests [1, 2], which benchmark the performance of network devices under reproducible, yet artificial conditions. Netbench is a network-testing framework, relying on commodity servers and NICs, that enables the evaluation of network devices performance for handling traffic-patterns that closely resemble real-life usage, at a reasonably affordable price. We will present the architecture of the Netbench framework, its capabilities and how they complement the use of specialized commercial testers (e.g. competing TCP flows that create temporary congestion provide a good benchmark of buffering capabilities in real-life scenarios). Last but not least, we will describe how CERN used Netbench for performing large scale tests with partial-mesh and full-mesh TCP flows [3], an essential validation point during its most recent high-end routers call for tender.

The Common

The ever-growing demand on information and data requires the efficient architecture for large-scale network storage systems. To serve very large scale applications, using inexpensive commodity becomes the common selection in nowadays cloud storage systems. Based on such unreliable hardware, building fault-tolerant mechanism is key issue to the system design. In this paper, we propose a rack-aware architecture for cloud storage systems.
