“…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 .…”

Summary This paper studies a problem for seamless migration of legacy networks of Internet service providers to a software‐defined networking (SDN)‐based architecture along with the transition to the full adoption of the Internet protocol version 6 (IPv6) connectivity. Migration of currently running legacy IPv4 networks into such new approaches requires either upgrades or replacement of existing networking devices and technologies that are actively operating. The joint migration to SDN and IPv6 network is considered to be vital in terms of migration cost optimization, skilled human resource management, and other critical factors. In this work, we first present the approaches of SDN and IPv6 migration in service providers' networks. Then, we present the common concerns of IPv6 and SDN migration with joint transition strategies so that the cost associated with joint migration is minimized to lower than that of the individual migration. For the incremental adoption of software‐defined IPv6 (SoDIP6) network with optimum migration cost, a greedy algorithm is proposed based on optimal path and the customer priority. Simulation and empirical analysis show that a unified transition planning to SoDIP6 network results in lower migration cost.

“…Gigabit Ethernet Passive Optical Network (GEPON), Data Over Cable Service Interface Specification (DOCSIS)), Net Field Programmable Gate Array (FPGA). Szalay et al [50], [51] propose HARMLESS, a framework that relies on a server to implement an SDN control plane legacy L2 switches. Every port has to be configured with a unique VLAN identification on a legacy switch and this configuration can be repeated in the rest of the switches.…”

Hybrid SDN evolution: A comprehensive survey of the state-of-the-art

Software-Defined Networking (SDN) is an evolutionary networking paradigm which has been adopted by large network and cloud providers, among which are Tech Giants. However, embracing a new and futuristic paradigm as an alternative to well-established and mature legacy networking paradigm requires a lot of time along with considerable financial resources and technical expertise. Consequently, many enterprises can not afford it. A compromise solution then is a hybrid networking environment (a.k.a. Hybrid SDN (hSDN)) in which SDN functionalities are leveraged while existing traditional network infrastructures are acknowledged.Recently, hSDN has been seen as a viable networking solution for a diverse range of businesses and organizations. Accordingly, the body of literature on hSDN research has improved remarkably. On this account, we present this paper as a comprehensive state-of-the-art survey which expands upon hSDN from many different perspectives.

“…With the development of SDN technology, legacy Ether-net switches are gradually migrating to SDN, and this process is harmless [ 32 ]. Although the emerging SDN networks that provides programmability to networks can have an improvement in implementing traffic engineering (TE), management departments still hesitate to deploy SDN fully because of various reasons such as budget constraints, risk considerations as well as service level agreement (SLA) guarantees.…”

For the law enforcement agencies, lawful interception is still one of the main means to intercept a suspect or address most illegal actions. Due to its centralized management, however, it is easy to implement in traditional networks, but the cost is high. In view of this restriction, this paper aims to exploit software-defined network (SDN) technology to contribute to the next generation of intelligent lawful interception technology, i.e., to optimize the deployment of intercept access points (IAPs) in hybrid software-defined networks where both SDN nodes and non-SDN nodes exist simultaneously. In order to deploy IAPs, this paper puts forward an improved equal-cost multi-path shortest path algorithm and accordingly proposes three SDN interception models: T interception model, ECMP-T interception model and Fermat-point interception model. Considering the location relevance of all intercepted targets and the operation and maintenance cost of operators from the global perspective, by the way, we further propose a restrictive minimum vertex cover algorithm (RMVCA) in hybrid SDN. Implementing different SDN interception algorithms based RMVCA in real-world topologies, we can reasonably deploy the best intercept access point and intercept the whole hybrid SDN with the least SDN nodes, as well as significantly optimize the deployment efficiency of IAPs and improve the intercept link coverage in hybrid SDN, contributing to the implementation of lawful interception.
