Analisis Konsep Virtualisasi pada Controller dalam Jaringan LAN berbasis Openflow

Abstract

Software defined networking (SDN) is a concept in networking technology to simplify the management and control of the network. One of the implementation of the SDN concept is Open flow protocol, which the main idea is to separate the function of control plane from the switching ASIC, by moving it to other device named controller. By doing the separation, the switch only has the data plane function. The se:19aration of control plane and data plane doesn't mean that the devices work individually as the switch still need instructions from the controller to operate. Controller could control one or many switches and they communicate between a dedicated control network. Besides the appearance of security vulnerable, that controller's characteristic makes network management more difficult to handle, especially if single controller used to handle all the network. Using emulation method, the author will analyze the vi1tualization concept in the controller. The result of this research to find an approach in controller configuration to optimize network management and security in a Open flow based LAN. The result of this emulated research could also be a reference in a real world network scenario.
