Aruba为北莱茵 - Westphalia的学校提供全面，安全的Wi-Fi，用于管理和教学
位于Kamp-Lintfort的Kommunales Rechenzentrum Niederrhein（Krzn，下莱茵莱茵城市数据中心）的300名员工看着市政厅和市政府的成员的12,000多名办公室工作站：Bottrop和Krefeld和Krefeld和Krefeld和Krefeld和Krefeld和Krefeld和Krefeld的城市克莱夫斯，维尔森和韦瑟尔地区。这使其成为德国十大市政IT服务提供商之一。该协会的角色包括IT应用程序的开发，引言，维护和操作以及数据保护和数据安全指标。
Schools need comprehensive Wi-Fi infrastructures
We chose Aruba because the solution runs in our own data centre. For data protection reasons, a cloud-based solution was out of the question for us. The Aruba AirWave management software gives us a scalable yet economical management solution we can use in-house at the data centre.安德烈亚斯Zboralski，Kommunales Rechenzentrum Niederrhein（KRZN）
Another of the KRZN's tasks is to supply the approximately 450 schools in the region, and their around 200,000 pupils and 8,000 teachers, with IT. Depending on their needs, the schools and education authorities can request a variety of support services, up to and including an on-site admin.
"Schools are calling more and more loudly for comprehensive Wi-Fi infrastructures so that their teachers and pupils can use mobile devices during or when preparing for lessons. Having comprehensive Wi-Fi coverage is essential for mobile learning and the flexible use of media in teaching," says Andreas Zboralski from the KRZN. "Vocational colleges and comprehensives are driving this. But even in primary schools, teachers and students are using smartphones and tablets in lessons – for example to look at nature photos they have taken together in the classroom." The schools also use applications such as email, a teaching and learning portal, the Moodle learning management system and a media database for online and rental media. All of this is provided as a service to the schools by the KRZN.
KRZN是该州的Wi-Fi先驱之一。大约十年前，它在Xanten和Moers的两所学校和Moers的两所学校创建了一个技术概念，并作为Euregio项目的一部分创建了一个技术概念。“因此，我们在这方面确实有一定的经验。这，我们的技术标准有助于我们在专业，单独，迅速地满足学校的Wi-Fi需求。”
所有学校的一致技术
KRZN根据教学人员，技术人员和数据保护官的要求制定了技术标准。Zboralski说：“对我们来说，建立一个一致的概念并拥有技术提供商，以便学校可以从标准化的模块化系统中选择自己的个人解决方案，这一点很重要。”KRZN不仅可以在组织层面上管理事情，还可以维护和支持，购买，库存，财务控制和与学校的互动。
Teachers wanted the solution to support certain apps and devices, including their own and students' private devices. They also wanted internet access to be secure with authentication required to join the network. And they wanted options for logging access. "It was also important for the Wi-Fi access points to be highly available throughout the entire school building, in staffrooms, classrooms, the hall, so that a large number of devices could be on the network simultaneously," continues Zboralski. "We needed plenty of bandwidth."
Good administration options, no cloud solutions
“从技术的角度来看，从我们作为IT服务提供商的角度来看，我们的要求最重要的是能够从我们的数据中心管理Wi-Fi基础架构，并且可以易于管理解决方案不要让我们的支持团队超负荷，” Zboralski继续说道。
各种基础设施的技术评估roviders concluded with a decision in favour of a comprehensive solution from Aruba. The KRZN is usingAruba 200和300系列802.11ac无线访问点- 后者通过2 Wave 2技术更快，更高效 -阿鲁巴空军用于网络管理。
Zboralski说：“我们之所以选择Aruba，是因为该解决方案在我们自己的数据中心中运行。出于数据保护原因，基于云的解决方案对我们来说是不可能的。”
Aruba Switch的良好经验
在KRZN决定使用Aruba的Wi-Fi基础架构的决定中，还有其他两个因素发挥了关键作用。首先，它已经与惠普企业达成了框架协议，而Aruba是其中的一部分。Zboralski解释说：“对于学校来说，这是他们不必为Aruba Airwave购买访问点和软件许可的招标而获得的好处。
其次，KRZN已经为客户管理了约800 Aruba 2530和2900系列开关。Zboralski高兴地说：“到目前为止，我们在Aruba的开关和服务方面拥有出色的经验，这在Wi-Fi基础架构中一直在继续。”
KRZN已经为20多所学校安装了全面的Aruba Wi-Fi基础设施。其中一些人具有室外天线的访问点，因此员工和学生可以在运动场和其他外部地区使用Wi-Fi。IT专家说：“ 400多个访问点非常稳定，我们根本没有任何失败。”但是，KRZN不得不在一些学校进行一些调整。在系统启动和运行之前，团队不知道在休息区或自助餐厅等地方的带宽没有足够的带宽，当时有太多的学生和老师通过Wi-Fi访问学校内容。在这些情况下，Aruba 200系列访问点可以快速，很容易被更强大的300系列型号取代。Zboralski说：“ Aruba解决方案提供了这种灵活性和可扩展性的水平。”
Schools are impressed
According to Zboralski, the feedback from the schools has been overwhelmingly positive. The number of access points normally varies between 20 and 50 depending on the size of the school. But smaller primaries can have far fewer. The KRZN expects that between 3,000 and 4,000 Aruba access points will be needed at its schools in the coming years. The state government of North Rhine-Westphalia is supporting the expansion of the infrastructure and the digital revolution in its schools with its "Gute Schule 2020" funding programme. The KRZN is currently preparing to install Wi-Fi infrastructures in all of the schools in Krefeld and Cleves, a total of more than 80.
Separating networks with different security levels
KRZN全面实施的一个标准是单独的网络：教师的管理网络，使用教育局的设备的教师和学生的教学网络以及教师和学生的私人设备的教学网络作为BYOD实施的一部分。Zboralski说：“我们可以通过ClearPass非常轻松地实现此分离的所有安全和访问概念。”这也适用于对设备或应用程序的灵活访问。例如，有些学校只想允许具有特定操作系统的平板电脑进入Wi-Fi网络，而另一些学校则希望阻止YouTube或WhatsApp等应用程序。
KRZN对Aruba Wi-Fi基础架构感到非常满意，以至于它将很快出于自己的目的而内部实施。
基于新的Web工作平台的运行中的ClearPass
Schools in the association might soon be using another Aruba product. On behalf of the North Rhine-Westphalian government and the region's municipal umbrella organisations, the KRZN and its partners have developed the basic infrastructure for LOGINEO NRW, a platform for the around 6,000 schools in the state. This protected, web-based work platform provides optimal communication, organisation and file management, for example with groupware applications and digital school books. Access is via single-sign-on.阿鲁巴ClearPass可以为Logineo NRW提供安全的网络访问控件。
ClearPass works with context-dependent policies. It offers transparency, policy control and workflow automation within a single, closed solution. When creating profiles with ClearPass, all devices are classified in order to define intelligent policies that determine access to cabled and wireless networks. The KRZN can grant or refuse user access permissions automatically based on the device type, owner status or the operating system.
