Abstract

To address the series of management issues caused by the serial connection of security devices in traditional network architecture, the Software Defined Network (SDN) architecture is applied to the design of campus network. This paper compares the advantages and disadvantages of existing network architectures, and proposes a network architecture based on SDN service chain resource pool. Through the reconstruction of the network architecture, it adopts the switch based on OpenFlow technology as the access platform, and the SDN controller is used as the forwarding layer to uniformly schedule all traffic. Then, High Availability (HA) technology is employed to ensure the reliability of the forwarding layer, aiming to establish a network with high flexibility, convenience, reliability, security and controllability. Finally, after long-term testing, it is fully proven to have achieved the pre-designed objectives.
