EDUCATION GUIDE
Primary, secondary, and higher education: From kindergarten to college, intelligent networks are in a class by themselves.
These are wondrous times in education: students and faculty are using technology to break down barriers, bring people together, and fire the imagination.
Intelligent networks are erasing the physical boundaries of the classroom, allowing learning to continue anywhere wired or wireless connections exist. They are linking people, buildings, campuses, and institutions as never before, allowing resources to be shared and ideas exchanged across any distance. And they are reinforcing lessons with rich, interactive content that engages the mind in powerful and memorable ways.
"We saw wireless as the next logical step for our network, since 25 percent of students have a laptop and that number will probably grow. We wanted to provide wireless service and have it up and running before the demand started, so we wouldn't be playing catch-up."
-Rusty Smith, Network Engineer, University of Wisconsin, Madison
Best of all, advancements in technology have made these and other benefits available to schools of every size and stature. Today's networks are simple and cost-effective to manage and own, so even organizations with limited expertise and resources can deploy sophisticated solutions to the challenges they face.
As this guide illustrates, colleges, universities, and primary and secondary schools around the world are using technologies such as intelligent switching, Gigabit Ethernet, wireless connectivity, and IP telephony to invigorate lessons, improve communications, automate administrative processes, safeguard important resources, and enhance the learning process in countless other ways.
Cisco Systems has helped numerous schools, school districts, colleges, and universities develop standards to deploy networking solutions tailored to their needs. Cisco offers end-to-end solutions that are designed to expand and evolve, allowing organizations to incrementally grow their networks as requirements change or new technologies emerge. Nowhere is this future-proof approach to networking more evident than in the Cisco Catalyst® fixed configuration and modular switch platforms. Offering basic connectivity or the power of Gigabit Ethernet, they can instantly boost network capacity to accommodate today's bandwidth-hungry applications, with plenty of room to grow tomorrow. That means any network, whether it's based on old copper telephone wires or the latest fiber-optic lines, can deliver the productivity and efficiency enjoyed by leading corporations.
"We relocated our offices in about 15 minutes (following a bomb threat) utilizing the Cisco IP phone technology, where we just literally unplugged our phones, brought them over here, and put a switch in place. Fifteen minutes later, all of our phones were operational, as if we were still in the central office. The technology was invaluable and allowed us to communicate with our schools and keep our business operations running smoothly."
-Mike Vasquenza, IT Director, Hartford, Connecticut public schools
Yet Cisco Catalyst switches offer more than raw speed-they extend intelligent services from the core of the network to the edge, where the students, teachers, and administrators are. This provides the advanced quality of service (QoS), high availability, and enhanced security needed to ensure everything operates efficiently, reliably, and securely as the network grows. These industry-leading features clear the way for new opportunities, such as wireless networking and IP telephony, further empowering students, faculty, and staff.
WITH CISCO SYSTEMS, IT'S EASY AND AFFORDABLE TO MAKE THE MOVE...
...From Hubs to Switches
To accommodate today's applications and demand for bandwidth, it's critical to replace any 10 megabits per second (Mbps) hub in the wiring closet with 100 Mbps Fast Ethernet or 1000 Mbps Gigabit Ethernet switches.
Unlike a hub, which forwards data packets to all connected ports, a switch forwards packets only to the port that matters-the one leading to their final destination. This reduces the overall volume of traffic on the network and enhances security, because packets are restricted to their designated ports.
Besides offering more bandwidth, Cisco Catalyst switches deliver intelligent services that enhance security and maximize network uptime. They also provide QoS features that identify types of traffic and prioritize how each packet is handled. This ensures that time-critical applications like voice and video transmissions-where delays can seriously affect quality-function properly.
Depending on the infrastructure in place, migrating from hubs to switches may be as simple as unplugging one and plugging in the other. Cisco Catalyst switches can integrate broadband into any network infrastructure, whether it uses Category 1, 2, or 3 copper telephone wire, Category 5 copper cabling, or fiber.
...To Gigabit Ethernet
The performance advantages of full Gigabit Ethernet switching are becoming increasingly essential for schools, districts, and campuses on the cutting edge of technology. The reason is simple. Today's bandwidth-hungry, time sensitive applications like video conferencing, real-time collaboration, and distance learning are putting greater stress on networks.
At speeds of 1000 Mbps, Gigabit Ethernet provides the bandwidth that networks need to evolve and meet new demands, alleviating bottlenecks, boosting performance, and increasing the return on existing investments in infrastructure.
As the industry leader in LAN switching, Cisco makes the transition to Gigabit Ethernet faster and easier with standards-based solutions for both fiber-optic and copper cabling. Cisco products can also be deployed in stages for a more gradual migration to Gigabit Ethernet, starting at the core and moving on to the wiring closet.
Schools and universities can use Cisco Catalyst switches to extend Gigabit Ethernet to the desktop, simply and affordably, to support today's powerful computers, sophisticated applications, and high traffic volumes. Delivering up to 10 gigabits per second (Gbps), the range of solutions offered by Cisco will satisfy even the most bandwidth-intensive requirements, including campus- and district-wide connectivity.
...To Converged Networks
Maintaining separate networks for voice, video, and data is no longer necessary-and is just plain inefficient. Merging all three services over a single network-known as convergence-is the obvious answer. And it is widely accepted and acknowledged by the communications industry and analysts that the Internet Protocol (IP) will become the standard way of delivering them.
Supporting everything from Web and e-mail access to telephone calls and videoconferencing, converged networks offer several benefits, including simplified administration, increased reliability and redundancy, and significant cost savings in terms of both IT resources and long-distance telephone charges.
The greatest demand today is for IP telephony, also known as voice over IP, an application that allows telephone calls to be carried over networks originally designed for data. The cost benefits of merging voice and data services onto one network can be dramatic. This is particularly true in education, since even the largest school districts and universities are often forced to hire outside contractors to manage separate networks.
Cisco Catalyst switches provide the advanced QoS features needed to support IP telephony, and are available with Power Over Ethernet (PoE) support. This PoE inline power mechanism adds network flexibility and scale by eliminating the need to rewire the infrastructure as separate power outlets are no longer needed to support network devices such as Cisco IP phones.
Cisco Systems is a recognized leader in network convergence. When appropriate, Cisco AVVID (Architecture for Voice, Video and Integrated Data) provides an open, standards-based foundation that makes it makes it easy to roll out IP telephony services and other Internet-based applications.
...To Wireless
Though much has been made of the freedom and mobility of wireless connectivity, its benefits go well beyond the basic luxury of "anytime, anywhere" network access. In some situations, this technology offers a simpler and more cost-effective alternative to traditional wired connections. In other cases, such as in historic buildings or areas where asbestos poses an environmental hazard, it may be the only viable means of extending high-speed network access. Even a fully wired campus can benefit from a wireless network, giving staff and students additional mobility and flexibility to teach and learn in new ways.
The Cisco Integrated Wireless Network sets the standard for reliable, secure, high-speed wireless connectivity. A range of equipment is available to meet different needs, including access points, controllers, management tools and client adapters for indoor wireless connectivity, and wireless bridges for long-range outdoor links between buildings. Wireless bridges deliver several times greater throughput than T1/E1 lines, eliminating the need to install fiber-optic cable or pay for leased line services.
"We were constantly reinstalling the fiber connections to keep the desktops and laptops in these classrooms connected with the campus LAN. With wireless, there's no need, since the mobile classrooms are always connected. We save a lot of money by not having to make these adjustments every year."
-Vass Johnson, Director of Networking, North Carolina's Wake County Public School System
Within buildings, Cisco Aironet access points provide constant access to network resources virtually anywhere these products are deployed. This not only gives network users the ability to roam freely throughout an extended area while maintaining uninterrupted network access, but saves organizations the time and expense of rewiring. Changes in the size or location of workgroups can be accommodated simply by adding or moving access points, further lowering facilities costs.
Cisco wireless technology is Wi-Fi™ compliant, making it ideal for a multivendor client environment. Advanced security features, scalability, and manageability allow network managers to easily deploy a wireless LAN within a complex campus environment.
Cisco Integrated Wireless Networks are designed for simple, rapid deployment. PoE support, for example, enables the access points to draw their operating power from Cisco Catalyst switches via Ethernet ports. Where no switch is available, inline power can be provided via a power injector. This eliminates the need for separate power sources, such as a wall outlet, greatly reducing the cost of installation.

ADVANCED FEATURES TO SUPPORT A RANGE OF NEEDS
Cisco Systems offers solutions to the challenges confronting education professionals. Common scenarios include:
Situation 1: Class sizes and room assignments are always changing-which means classroom networking requirements are too.
Solution: Wireless access can be quickly integrated into any environment, eliminating the time and expense associated with rewiring classrooms and labs as requirements change. Cisco Aironet access points let you instantly extend wireless connectivity to everyone in the room, or even beyond the room, allowing teachers and professors to take classes outside while maintaining network access. Many schools and colleges have set up carts with Cisco Aironet access points and wireless notebook computers using Cisco Aironet client cards, creating "mobile wireless classrooms" that can be used to extend network resources whenever and wherever they're needed, so classes aren't disrupted by moving students to a computer lab. Cisco Catalyst switches support wireless networking with inline power options, which enable Cisco Aironet access points to draw operating power from the network connection, eliminating the need for separate power sources. Wireless technology can also be used to connect remote classrooms or offices, eliminating the need for leased lines or cabling. Cisco Aironet 350 Series Wireless Bridges provide high-speed links between buildings up to 25 miles (40.2 km) apart.
Situation 2: There aren't enough phone lines to go around. But the setup costs for expanding the existing PBX phone system are extremely high.
Solution: Converging voice and data onto a single network offers dramatic cost benefits, eliminating the need for services and equipment needed to maintain a separate phone system. Cisco IP telephony makes it affordable for each teacher to have a phone with voice mail, improving communication with colleagues and parents, while also ensuring help can immediately be summoned in the event of an emergency. Cisco IP phones dramatically simplify location changes as well, since they can be moved anywhere on the network and their extensions remain the same. Converged networking also enables IP phones to be used for other things, such as attendance tracking and announcements over the school's public-address system. Meanwhile, Cisco Catalyst switches can be used to provide network-based inline power for Cisco IP phones, eliminating the need for separate power sources.
Situation 3: There's so much great educational software and multimedia content available these days, it would be great to incorporate it into lesson plans. The trick is distributing it to students, and keeping different classes in sync.
Solution: Cisco Catalyst switches make it easy to implement and manage video multicasts, providing the advanced QoS and multicast features needed to support broadcast-quality video. Educational content can be stored on a Cisco IP/TV® server, so it's always available on demand. Cisco video-over-IP technology also supports videoconferencing for enhanced communication and collaboration.
Situation 4: Warranted or not, there are growing concerns about personal safety on campus. But major expenditures on staff or equipment are out of the question.
Solution: The same multiservice network that supports video-conferencing and e-learning applications also supports a potent, yet inexpensive security measure: IP video surveillance. IP video cameras plug directly into the local- or wide-area network, eliminating the need to rewire a building or campus. Yet they are just as much a deterrent to crime as a conventional surveillance system-and just as reassuring to students and staff.
Situation 5: Heavy network traffic during peak times of the school day decrease network response times. This hinders network performance for important applications, such as delivering bandwidth-intensive e-learning content.
Solution: Cisco Catalyst switches offer extensive network monitoring capabilities, making it easy to track granular traffic details on the network at all times. Advanced QoS and rate-limiting features allow traffic to be prioritized and controlled, so critical applications and staff are given the bandwidth they need, without starving other users.
Situation 6: The unauthorized use of network resources is a major concern. In some cases, the problem is as simple as students wasting precious bandwidth downloading large music and video files. In others, the threat is much more serious, involving deliberate attempts to access or damage sensitive data and other resources.
Solution: Cisco Catalyst switches provide an array of security and management features to safeguard the network from internal and external threats. Access control lists, for example, can be easily configured to repel unwanted visitors, monitor communications, and filter content, ensuring the network is used appropriately. Meanwhile, rate limiting provides desktop-level control over the amount of bandwidth available to users, helping to ensure network resources are not being used inappropriately.
