Legacy Network Integration with SDN-IP Implementation towards a Multi-Domain SoDIP6 Network Environment

Abstract

The logical separation of the data plane and the control plane of the network device conceptually defined by software-defined networking (SDN) creates many opportunities to create smart networking with better efficiency for network management and operation. SDN implementation over telecommunications (Telcos) and Internet service provider (ISP) networks is a challenging issue due to the lack of a high maturity level of SDN-based standards and several other critical factors that are considered during the real-time migration of existing legacy IPv4 networks. Different migration approaches have been studied; however, none of them seem to be close to realizing implementation. This paper implements the SDN-IP and Open Network Operating System (ONOS) SDN controller to migrate legacy IPv4 networks to multi-domain software-defined IPv6 (SoDIP6) networks and experimentally evaluate the viability of joint network migration in the ISP networks. We present results using extensive simulations for the suitable placement of the master ONOS controller during network migration by considering minimum control path latency using optimal path routing and the breadth first router replacement (BFR) technique. Our empirical analysis and evaluations show that the identification of the median router to attach the master controller and router migration planning using BFR give better results for carrier-grade legacy networks’ migration to SoDIP6 networks.

Migration cost optimization for service provider legacy network migration to software‐defined IPv6 network

“…The decision to activate legacy or OpenFlow communication is based on where the traffic to be destined. Experiments by ON.LAB 50 and studies by different authors 7,53–57 indicate that migration to a hybrid network is viable. The L2M approach is also recognized as L2H approach in some literature 15,58 .…”

Controller placement problem during SDN deployment in the ISP/Telco networks: A survey

“…A suitable strategy is required to find the controller and install more controllers in the network for load balancing in order to handle the issue of increased control traffic with the rise of SDN switches. 98 An effective load balancing technique for numerous controllers in SDN is created by the research in Zhong et al 114 A SCPLBS on SDN distributed controllers is presented. The time that controllers use to collect and publish loads can be changed adaptively.…”

Multi-Controller Placement Optimization Using Naked Mole-Rat Algorithm over Software-Defined Networking Environment

“…Te number of controllers that must be assigned to switches and their right location in SDN is a critical factor in attaining a faster fow setup time with improved fault management and controller load balancing [4].…”

“…During the real-time migration of an existing legacy network into a Software Defned IPv6 (SoDIP6) network, the appropriate location of the SDN control plane is determined by evaluating the shortest control route latency utilizing optimum path routing and the Breadth-First Router Replacement (BFR) approach [4]. According to their simulation results, the BFR strategy for controller placement and router migrations outperforms sequential router migrations in the best path.…”
