IPv6承载的互联网流量比例继续快速增长。网络硬件供应商和运营商对IPv6的支持已经普遍存在并且变得成熟。网络基础设施升级通常为站点提供配置和启用IPv6的绝佳机会。在设置和维护双栈机器时会有很大的开销，因此在可能的情况下，站点希望将其服务直接升级到IPv6。在这样做的同时，他们也在加快过渡进程，以实现预期的完成。虽然LHC实验承认有必要迁移到IPv6，但它目前并没有直接影响他们的工作。如果站点无法运行LHC实验工作流程，则不愿意升级。这导致WLCG站点对IPv6的吸收非常缓慢。几年来，HEPiX IPv6工作组一直在测试一系列WLCG服务，以确保它们符合IPv6标准。现在有几个站点正在以双栈的形式运行他们的许多服务。在LHC VO能够使用纯IPv6机会资源的需求的驱动下，工作组继续鼓励更广泛地部署双栈服务，以使这种纯IPv6客户端的使用变得可行。本文介绍了工作组的计划和进展，到目前为止，允许网站部署IPv6的CPU资源。这包括使实验中心服务双栈以及一些存储服务。就业所使用的监测、会计和信息服务也需要升级。最后，VO测试，已通过IPv6连接的主机上发生的唯一报告。
The fraction of Internet traffic carried over IPv6 continues to grow rapidly. IPv6 support from network hardware vendors and carriers is pervasive and becoming mature. A network infrastructure upgrade often offers sites an excellent window of opportunity to configure and enable IPv6. There is a significant overhead when setting up and maintaining dual-stack machines, so where possible sites would like to upgrade their services directly to IPv6 only. In doing so, they are also expediting the transition process towards its desired completion. While the LHC experiments accept there is a need to move to IPv6, it is currently not directly affecting their work. Sites are unwilling to upgrade if they will be unable to run LHC experiment workflows. This has resulted in a very slow uptake of IPv6 from WLCG sites. For several years the HEPiX IPv6 Working Group has been testing a range of WLCG services to ensure they are IPv6 compliant. Several sites are now running many of their services as dual-stack. The working group, driven by the requirements of the LHC VOs to be able to use IPv6-only opportunistic resources, continues to encourage wider deployment of dual-stack services to make the use of such IPv6-only clients viable. This paper presents the working group’s plan and progress so far to allow sites to deploy IPv6-only CPU resources. This includes making experiment central services dual-stack as well as a number of storage services. The monitoring, accounting and information services that are used by jobs also need to be upgraded. Finally the VO testing that has taken place on hosts connected via IPv6-only is reported.
