Abstract (Summary)

Hybrid Software Defined Network(Hybrid-SDN) is the most popular topic in recent years, with related development and deployment of vendors of software and hardware. HybridSDN has the capabilities of most advantaged technology and features with the network current on use in public. However, the Hybrid-SDN does not have the highest performance which is the pure SDN network architecture. It is necessary for researchers understand the differences between legacy network, SDN and Hybrid-SDN, through the numeric comparison of performances by simulations. Also, as the cooperation part between the legacy nodes and SDN nodes in Hybrid-SDN network architecture, load balancing algorithm played an important role. There are lots of load balancing algorithm comes out since the network architecture first time constructed. But the different between load balancing algorithms are not clear. It is necessary for researchers know is there existing difference between load balancing algorithms. Also, particular for Hybrid-SDN network architecture, the messed up environment of different type of devices, the current existing load balancing algorithm did not considering all the cases may affect the network. The solution for the problem is to design a load balancing algorithm which particular focusing on Hybrid-SDN environment. To explain the differences of these framework and design the load balancing algorithm, we studied different network architectures and load balancing algorithms, evaluated them by simulation results. The main work included the following tasks:

• Simulated three network architectures. • Simulated two common load balancing algorithms. • Designed a load balancing algorithm for flow management focus on Hybrid-SDN

The simulation results of three network architectures provided the clearly differences between these architectures, which approve the Hybrid-SDN has a big performance promotion with Legacy Network. The results of two load balancing algorithms showed there existing difference between load balancing algorithms, so that, it is necessary to have a load balancing algorithm particular focusing on Hybrid-SDN. And both analysis and simulation results dedicated that our proposed load balancing algorithm can perform efficiently for Hybrid-SDN network architecture.
