Implementation of Layer 2 MPLS VPN on the SDN Hybrid Network using Ansible and ONOS Controllers

L2VPN AToM (Any Transport over MPLS) is an ethernet-based private communication service that can connect networks in different geographical locations but seems to be on the same network logically through MPLS networks on the same bridge domain. L2VPN AToM technology is a consideration in enterprise networks to manage the availability of data sources centrally, safely, and quickly with other branch offices. L2VPN AToM becomes inefficient and inflexible in managing large networks formed between the head office and branch offices which must be configured manually one by one as many as the number of branch offices to be connected. In managing the L2VPN AToM network configuration, it can be done centrally to improve network efficiency by using the SDN architecture. However, this architecture requires a long time in the transition process and considering the costs incurred to replace conventional network devices that are already operating. For the solution, Hybrid SDN (Software Defined Network) network technology is needed as a solution to centrally manage conventional networks. Hybrid SDN Network is a technology that separates the control plane and the data plane by utilizing conventional network devices to be applied to the SDN architecture. This research used ansible as a controller that will distribute conventional network configuration centrally and an ONOS controller as a traffic management service for L2VPN AToM traffic. The research result shows that Hybrid SDN networks are better than conventional networks with different average values of throughput in 3.12%, 2.12% of delay, and 0.3% packet loss.
