Abstract:
Here it is described a study of possibilities to build up and test the performance of the software defined network (SDN) segments. The applicability of the SDN for data centers and the distributed storage systems. We describe experiments on stress testing of the storage area networks with the use of NOX controller and various software and hardware OpenFlow switches. A check on the possibility of processing bulk client requests, measured response delay, carried out experiments to simulate the operation of data center with 64 switches and 100 thousands hosts. The comparative results of the effectiveness of specific mechanisms implementing QoS are presented. The main problems of existing implementations of OpenFlow SDN components identified during the work and recommendations on possible ways to address them are described.

Abstract:
The purpose of the study are software-defined network (SDN) OpenFlow and effectiveness of their approach to build a network storage. Here we present the study how to build up and study of operating characteristics of software-configurable networks. Prototyping tools for managing network resources and data flows on the basis of the SDN are described. The estimation of the SDN approach for data centers (DC) and the distributed storage systems is observed. We describe experiments with various modifications of OpenFlow controller NOX and set out the specifics of the use of various software and hardware OpenFlow switches. We provide comparative performance results of specific QoS methods. A description of the main problems of existing implementations of OpenFlow SDN components identified during the research, and recommendations on possible ways to address them are provided.
