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.

服务提供商遗留网络迁移到软件定义的 IPv6 网络的迁移成本优化

本文研究了将互联网服务提供商的传统网络无缝迁移到基于软件定义网络 (SDN) 的架构以及全面采用互联网协议版本 6 (IPv6) 连接的问题。将当前运行的传统 IPv4 网络迁移到此类新方法需要升级或更换正在运行的现有网络设备和技术。就迁移成本优化、熟练的人力资源管理和其他关键因素而言，向 SDN 和 IPv6 网络的联合迁移被认为是至关重要的。在这项工作中，我们首先介绍了服务提供商网络中 SDN 和 IPv6 迁移的方法。然后，我们通过联合转换策略提出 IPv6 和 SDN 迁移的共同关注点，以便将与联合迁移相关的成本最小化到低于单独迁移的成本。针对具有最优迁移成本的软件定义IPv6（SoDIP6）网络的增量采用，提出了一种基于最优路径和客户优先级的贪心算法。仿真和实证分析表明，统一过渡规划到 SoDIP6 网络可以降低迁移成本。
