Experimental evaluation of software defined passive optical network with network coding

Facing with the huge P2P traffic challenge, network coding shows great advantages in improving system efficiency. This paper proposed a solution to integrate network coding into passive optical networks and compatible with the existing Ethernet passive optical network named NC-PON. To increase more efficiency, a software defined passive optical networks with network coding (SDNC-PON), which combines the software defined technology and network coding, was proposed to optimize the P2P traffic under different OLTs. The core idea of SDNC-PON is to change the owner-member relationship between OLTs and ONUs flexibly to achieve the maximum traffic benefit. The results of experimental platform and the simulations indicated that the proposed architecture is efficient and with network flexibility.
