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
• Managing the influx of IoT devices being connected by students in the residence halls
• And, simplifying the way that users connect, regardless of location or access method

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.

With Aruba wireless, students get a reliable and secure experience with a single SSID whether they're reviewing lessons or taking tests in the classroom. Services like Wi-Fi calling, Netflix streaming or posting to social media are now possible anywhere within a residence hall.

查普曼（Chapman）企业和研究基础设施助理副总裁菲利普·莱尔（Phillip Lyle）说：“有了我们的旧无线提供商，我们会听到有关学生在连接方面遇到问题的抱怨。”“当150名学生中有5至10名学生遇到问题时，这是一件大事。自切换到Aruba Wireless以来，投诉的数量大大减少。”

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Poll Everywherewithin the classroom, which enables them to get real-time feedback during a lecture or discussion.

"Wireless, in many classes, has become a hard and fast requirement for teaching," Lyle says. "Now we simply rely on Aruba's wireless software technology to balance the traffic load at the AP level."

Saving time with better insights and network management features

For Chapman's IT department, simplifying the management of the wireless network and gaining more visibility into it was key when deciding to go with Aruba. In some cases, it meant no longer having to manually tune each individual access point.

"We've been able to rely on features within AirWave to automatically determine settings for the individual access points, such as channel and power selection," says Mike Ferguson, Network Operations Manager at Chapman. "Our team has saved a tremendous amount of time when it comes to optimizing an environment or bringing up a new building."

Troubleshooting also became easier, not only does空波show what's currently happening with a client but what had happened in the past.

莱尔说：“我们之所以选择阿鲁巴是因为我们觉得从可管理性的角度获得了总包裹。”“由于过去几年我们部署了数千个访问点，它已经为我们带来了股息。”

简单的物联网和来宾访问注册

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 Clearpassso students can register their own devices. Students are using it every day and IT benefits by understanding what is connected, how many devices are being used and which devices belong to each student.

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。”

Aruba Wired Within Two New Buildings

Two parallel events occurred that gave Chapman the opportunity to bring Aruba wired connectivity onto the campuses, which already were 100 percent Aruba wireless. The first was the opening of its new凯克科学与工程中心, a 140,000-square-foot building that houses Chapman's Schmid College of Science and Technology and will eventually include its new Fowler School of Engineering.

The second was theChapman Grand residential building，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。

Connecting the sciences building for the future

With Keck Center, Chapman opted forAruba 3800 Switch Series and 2930F Layer 3 switchesfor aggregation andAruba 300系列APS. Multi-rate capable switches helped meet increasing bandwidth demands, as the building houses a shared core lab for high-resolution imaging, world-class high-performance computing facility and a wide range of collaboration spaces.

There are plans to utilize ClearPass' ability to automatically enforce what can be connected down to the port level on switches. Aruba Dynamic Segmentation is a feature that will also allow Chapman to leverage their wireless infrastructure to automatically segment a device and its traffic on wired and wireless, regardless of location.

Zero-touch provisioning in the new residential hall

对于查普曼大公寓式的大楼，查普曼不得不将传统公寓楼过渡到适合学生的住宅大厅。该团队选择了每个房间中的2930m系列第3层开关。对于无线，查普曼在其他每个房间以及走廊和户外都使用300系AP。

"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."

更多的方式

In the future, Chapman is looking to expand its Aruba partnership with plans to leverage their new infrastructure to its full potential. One such product is阿鲁巴岛子午线, 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。
