加利福尼亚大学每天简化13k+用户的连接体验

As an institution that prides itself on offering personalized education, it was imperative that Chapman University deliver a premiere connected experience for students, faculty and staff. With more than 9,000 students, 920 faculty and 60+ buildings stretched over both its main campus in Orange, CA, and Rinker Health Science campus in Irvine, Chapman was experiencing spotty coverage, frequent disconnects and a lack of consistent network security as students roamed inside and between buildings.

在任何一天，最多13,000个设备一次连接到网络。启用简单的设备连接，同时也知道这些设备是什么以及它们所属的人至关重要。此外，查普曼的IT团队需要解决以下挑战：

• 安装无线解决方案，该解决方案将满足不断增长的语音，电子学习和云应用程序的使用
• 管理宿舍中学生连接的物联网设备的涌入
• 并且，无论位置或访问方法如何，简化用户连接的方式

无线使轻松安全

Chapman quickly replaced an open wireless configuration with a role-based, 802.1X model using Aruba wireless and ClearPass to simplify and secure the network. Students and staff were able to connect from anywhere using EDUROAM credentials and IT was able to easily segment student and staff traffic from guest traffic.

借助Aruba Wireless，无论是在课堂上审查课程还是在课堂上参加考试，学生都可以通过单个SSID获得可靠和安全的体验。现在可以在宿舍内的任何地方进行诸如Wi-Fi通话，Netflix流媒体或发布到社交媒体之类的服务。

"With our old wireless provider, we would hear complaints about students having problems connecting," Phillip Lyle, Assistant Vice President of Enterprise and Research Infrastructure at Chapman, says. "When 5 to 10 students out of 150 have an issue, it's a big deal. Ever since switching to Aruba wireless, the number of complaints have diminished considerably."

丰富Wi-Fi体验

Historically, throttles were applied at the wireless access point level due to concerns about contention and one user eating up all the bandwidth. As more and more voice and video apps are being used, there are no bandwidth restrictions on student, staff or guest connections.

这对于越来越依赖教室中移动设备来提供互动内容的教师很重要。他们还取决于学生使用受众参与应用程序的能力，例如到处都是民意调查在教室里，这使他们能够在讲座或讨论期间获得实时反馈。

莱尔说：“在许多班级中，无线已成为教学的艰难和快速要求。”“现在，我们只是依靠Aruba的无线软件技术来平衡AP级别的流量负载。”

通过更好的见解和网络管理功能节省时间

对于查普曼的IT部门而言，简化无线网络的管理并在决定与Aruba时获得更多的可见性是关键。在某些情况下，这意味着不再需要手动调整每个单独的访问点。

查普曼（Chapman）网络运营经理Mike Ferguson说：“我们已经能够依靠Airwave中的功能自动确定单个访问点的设置，例如渠道和电源选择。”“我们的团队在优化环境或建立新建筑方面节省了大量时间。”

故障排除也变得更加容易，不仅如此空波显示客户目前发生的事情，但过去发生了什么。

"The reason why we chose Aruba was because we felt we were getting a total package from the manageability perspective," Lyle says. "It has paid out in dividends for us as we've deployed thousands of access points over the last several years."

Simple IoT and Guest Access Registration

在当今的大学校园中，学生会定期携带设备，例如亚马逊Echo或Google Home，Game Consoles和Apple TV。用于简化和自动化控件，收集和监视大学信息的设备和系统也对其进行了影响。

To enhance the BYOD onboarding experience, Chapman is using the built-in device registration portal withinAruba Clearpass因此学生可以注册自己的设备。学生每天都在使用它，它通过了解连接的内容，使用了多少个设备以及哪些设备属于每个学生来受益。

ClearPass中易于使用的访客访问门户网站还使访问者可以自行注册以获取Internet访问。来宾角色自动提供了一个额外的好处，为查普曼提供了一种从学生，员工和教师流量中分割访客流量的方式。

弗格森说：“ ClearPass可以帮助我们管理这一切。”“我们正在使用它来简化用户如何通过定义角色获得访问和隔离流量，同时使用Aruba控制器和无线基础架构来细分流量，以免影响学习体验。”

阿鲁巴Wired Within Two New Buildings

发生了两次平行事件，使查普曼有机会将Aruba有线连通性带到校园，这已经是Aruba Wireless的100％。首先是其新的开放凯克科学与工程中心这是一栋140,000平方英尺的建筑，可容纳查普曼科学技术学院，最终将包括其新的福勒工程学院。

The second was the查普曼大型住宅大楼，一栋经过改建的公寓楼，容纳约900名学生。这两座建筑物的计划在2018年秋季开放 - 不仅要在整个过程中使用Aruba Wireless，还可以使用Aruba有线开关。能够利用ClearPass和Aruba的无线软件的功能，使在有线壁橱中选择Aruba成为一个简单的决定。

连接未来的科学大楼

With Keck Center, Chapman opted forAruba 3800开关系列和2930F第3层开关用于聚合和Aruba 300系列APS。多速率的开关有助于满足不断增长的带宽需求，因为该建筑物设有一个共享的核心实验室，用于高分辨率成像，世界一流的高性能计算设施和广泛的协作空间。

有计划利用ClearPass的能力来自动执行可以连接到交换机端口级别的功能。Aruba Dynamic分割是一项功能，还可以使Chapman利用其无线基础架构自动将设备及其流量分割在有线和无线上，无论位置如何。

新住宅大厅的零接触式供应

查普曼的大公寓式建筑、Chapman had to transition what had been traditional apartment building into a residential hall that is fitted for students. The team opted for an individual 2930M Series Layer 3 switch in each room. For wireless, Chapman is using 300 Series APs in every other room as well as in the hallways and outdoors.

"We had 400 rooms and 400 switches, and we had to install everything in a short amount of time," Lyle mentioned. "With Aruba, we were able to save time by using zero-touch provisioning to get every single apartment in the building online very quickly."

将来，查普曼（Chapman）希望扩大其Aruba合作伙伴关系，并计划利用其新基础设施发挥其全部潜力。一个这样的产品是阿鲁巴子午线, which would allow students and visitors to use a mobile app and location awareness to easily navigate the campus and within buildings.

"We are excited by the possibilities of Meridian," Lyle says, adding that the PoC will run in about three buildings on the University's Rinker Health Science campus in Irvine. The primary purpose is to support public safety with an application called关键。

查普曼还正在评估Aruba NetinSight用于实时网络分析，并将升级其无线部署，其中包括Aruba 500系列802.11ax AP和Arubaos 8在夏季，利用实时升级和AI驱动的RF管理功能。
