“…Though SDN implementation in datacenter networks is popular, its proper implementation with the migration of a legacy network to carrier grade ISP (CG-ISP) and telecommunication (Telcos) networks is becoming a central challenge for service providers due to the need for real time migration as well as the higher cost of investment [2,3]. Additionally, real time implementation of SDN in production networks is the subject of ongoing research.…”

Legacy IPv4 networks are strenuous to manage and operate. Network operators are in need of minimizing the capital and operational expenditure of running network infrastructure. The implementation of software-defined networking (SDN) addresses those issues by minimizing the expenditures in the long run. Legacy networks need to integrate with the SDN networks for smooth migration towards the fully functional SDN environment. In this paper, we compare the network performance of the legacy network with the SDN network for IP routing in order to determine the feasibility of the SDN deployment in the Internet Service provider (ISP) network. The simulation of the network is performed in the Mininet test-bed and the network traffic is generated using a distributed Internet traffic generator. An open network operating system is used as a controller for the SDN network, in which the SDN-IP application is used for IP routing. Round trip time, bandwidth, and packet transmission rate from both SDN and legacy networks are first collected and then the comparison is made. We found that SDN-IP performs better in terms of bandwidth and latency as compared to legacy routing. The experimental analysis of interoperability between SDN and legacy networks shows that SDN implementation in a production level carrier-grade ISP network is viable and progressive.

“…Migration to SDN in telecom operators’ (Telcos) and Internet service providers’ (ISP) networks have evolved with significant progress on developing transition technologies [ 12 , 20 , 21 ]. In this regard, based on the inter-relationship defined between SDN and IPv6 networking paradigms, we have developed the proper transition planning and migration cost minimization with their benefits and challenges of migration for joint migration to the SoDIP6 network in our previous works [ 9 , 13 , 17 , 22 , 23 , 24 ].…”

“…We found limited literature for the incremental deployment of SDN and IPv6 networks with an overall migration plan for ISPs and Telcos. For example, studies like the game theoretic approach on IPv6 network migration [ 28 ], incremental adoption to IPv6 networks [ 29 ], evolutionary process on SoDIP6 network migration [ 17 ], agent-based modeling for joint migration to IEEE-PCE and SDN [ 30 ], SoDIP6 network migration based on customer priority, and optimal path [ 13 , 22 ], incremental deployment of hybrid SDN in service provider networks [ 31 , 32 , 33 , 34 ] and optimal sequence of router replacement using greedy algorithm for SDN migration [ 21 ] are those studies, which provide insights into individual and joint network migration. However, these studies were all concerned with the migration to be implemented only after finding the status of a device whether to migrate or upgrade.…”

“…However, all networking devices could not be upgradable to newer technologies at a time. Additionally, based on the interrelationship between IPv6 and SDN, joint migration decision being taken by service providers towards SDN and IPv6 networks migration is more cost effective than individual migration implementation [ 13 , 14 ]. The major steps for service providers for joint network migration to SDN and IPv6 are: Assess the device performance and status towards the possibility of their hardware/firmware upgrades or replace the equipment with a newer one to make it operable with newer networking paradigms viz.…”

Internet and telecom service providers worldwide are facing financial sustainability issues in migrating their existing legacy IPv4 networking system due to backward compatibility issues with the latest generation networking paradigms viz. Internet protocol version 6 (IPv6) and software-defined networking (SDN). Bench marking of existing networking devices is required to identify their status whether the existing running devices are upgradable or need replacement to make them operable with SDN and IPv6 networking so that internet and telecom service providers can properly plan their network migration to optimize capital and operational expenditures for future sustainability. In this paper, we implement “adaptive neuro fuzzy inference system (ANFIS)”, a well-known intelligent approach for network device status identification to classify whether a network device is upgradable or requires replacement. Similarly, we establish a knowledge base (KB) system to store the information of device internetwork operating system (IoS)/firmware version, its SDN, and IPv6 support with end-of-life and end-of-support. For input to ANFIS, device performance metrics such as average CPU utilization, throughput, and memory capacity are retrieved and mapped with data from KB. We run the experiment with other well-known classification methods, for example, support vector machine (SVM), fine tree, and liner regression to compare performance results with ANFIS. The comparative results show that the ANFIS-based classification approach is more accurate and optimal than other methods. For service providers with a large number of network devices, this approach assists them to properly classify the device and make a decision for the smooth transitioning to SDN-enabled IPv6 networks.

Summary With the aid of network coding, numerous packets can be mixed at intermediary nodes if any encoding opportunity exists. However, it is challenging to choose intermediate relay nodes of probable opportunistic coding in distributed wireless networks. In this work, a wireless sensor network (WSN) is employed with a software defined network (SDN) architecture along with a connected dominating set (CDS)‐based routing technique. The SDN offers a centrally managed architecture that lowers energy usage and network traffic by reducing the controlling and managing overheads in sensory networks. In addition, the CDS‐based routing and the potential for opportunistic coding at dominant nodes are coupled to enhance network performance. The proposed CDS‐based flow‐oriented coding‐aware energy‐efficient routing (CFCER) is contrasted with existing traditional wireless sensor networks and software‐defined sensor networks in terms of throughput, packet delay, and energy usage. CFCER increases network throughput by 15% more than SDN‐based WSN and by about 25% more than traditional WSN. However, compared to standard WSN, a significant improvement was made in packet delay and energy conservation. Over SDN‐WSN, packet delay is reduced by about 18%, and the energy consumption is cut by 10%.
