Moreover, now that almost all of a school’s information is digital — from student grades to employee information to building finances — districts need to make access a high priority. This project, design and implementation of wireless local area network was written to serve as a reference book for wireless LAN in the future whenever it is desired. However the convergence times of the routed access layer are much less than that of the flat Layer-2 network. Software-based QoS functions can easily overwhelm the CPUs of networking devices. These features allow two or more distribution switches to be combined into a single virtual switch from a management and data forwarding perspective. •Cisco LCD Professional Series Displays are an integral part of the Digital Media System (DMS) suite of products and are used to display information. It supports established video formats such as Windows Media, Flash, and MPEG/H.264. –HSRP/VRRP is no longer needed to provide host redundancy. There are several design changes and software features that can be implemented to improve availability in the access layer. He was named as a Digital Principal of the Year by NASSP for exhibiting bold, creative leadership in his drive to harness the potential of new technologies to further learning goals for staff, students, and the school community. Integrated voice, video, and Web conferences can be set up and attended in a single step from IP phones, instant messaging clients, Web browsers, and Microsoft Outlook and IBM Lotus Notes calendars. For 16 years Ann led the team in Klein ISD that provided professional development on technology and 21st century instructional strategies to over 4,000 professional educators serving over 50,000 students. Because many of the services are centrally located within the district office, rather than within each school itself, high network availability must be maintained. For example, call control and presence can be launched and managed from within Microsoft Outlook through a Cisco Unified Personal Communicator widget or toolbar. First, a loop-free topology is created. Network Analysis and Design Documents. Cisco Secure ACS is a central point for administering security policy for users and devices accessing the network. Pre-sales proposal for network setup in a university. Some of these technologies include: •A reliable firewall is the hallmark of a secure network. Instead of providing only point products that set a base level of security, Cisco embeds firewall security throughout the network and integrates security services in all of its products. Today, Ann is based in Los Angeles, California, working as a public speaker, writer, and independent education consultant focused on supporting leadership, visioning and planning to meet the needs of today’s students. A network has to be designed for a school. The architecture has been designed around both school operations and technical considerations. Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. Pre-drawn network shapes are provided, including 3D computers, network devices, and smart connectors. Figure 2-4 highlights this technology. She is a frequent presenter at state, national and international education conferences. The system can scale to one million users across 1000 sites or more or 60,000 users within a single clustered system. There is some debate in the networking industry about the need to deploy QoS in enterprise architectures because of the ample amounts of bandwidth that make congestion rare. Figure 2-4 Cisco's Virtual Switching Systems. –Management processes—Consistency of processes, minimize service times, etc. Operating on top of this network are all the services used within the school district, such as safety and security systems, voice communications, video surveillance, etc. IP technology has extended beyond the data network and is now used extensively for voice and video communication as well. All of these standards-based systems work with an array of third-party phones and dual-mode devices. No longer are networks used solely to provide data communication between computers. These symbols and examples can help you design accurate network diagrams quickly, and you are able to save and share your own network diagrams with your team … •Network operations and configuration management: –Management tools—Simplify provisioning, configuration management, troubleshooting. The Basic Network Diagram is an easy and effective way to design and document a simple network, it lets to represent visually and logically how the different network devices and computer equipment can be installed to meet the main business needs. This means spanning tree does not impact re-convergence times. Figure 2-2 Second Network Shows End-to-End Redundant Paths. http://www.cisco.com/en/US/docs/solutions/Enterprise/WAN_and_MAN/QoS_SRND/QoS-SRND-Book.html, http://www.cisco.com/en/US/netsol/ns818/networking_solutions_program_home.html, http://www.cisco.com/en/US/netsol/ns929/networking_solutions_sub_program_home.html, http://www.cisco.com/en/US/netsol/ns820/networking_solutions_program_home.html, http://www.cisco.com/en/US/netsol/ns744/networking_solutions_program_home.html. –Resilience—Ability to function when the network is in a degraded state from an attack, misconfiguration, maintenance window, etc. For more information, refer to the following URL: http://www.cisco.com/en/US/netsol/ns820/networking_solutions_program_home.html. In educational environments, video documentation of critical incidents enhances student safety and better protects valuable assets. •Embed service recognition, awareness, and differentiation into all components. Users can navigate through channel menus and select from on-demand content with a remote control or other remote devices. Cisco presence and instant messaging solutions work in conjunction with Cisco Unified Communications Manager and support Cisco Unified Personal Communicator, Cisco IP phones, Cisco IP Phone Messenger, IBM Sametime clients, and Microsoft clients. During a recent webinar hosted by edWeb.net — entitled “Smart Network Design for Transformation and Innovation: Reaching in and Beyond the Classroom” — two educational technology leaders reviewed the six elements of new network design for continuous service conceived by the Consortium for School Networking. Intended Users The users of the network will be the two owners/administrators, 12 full time employees and 5 part time employees. Through the presentation of dynamic presence information, presence solutions allow users to check the availability of colleagues in real time, reducing phone tag and improving productivity. “The weakest link in any security — whether it’s infrastructure, whether it’s a building, whether it’s your house — is the human element,” Robbins said. A typical use of network diagram is for tracking down network issues by studying how the computers and devices are connected and inter-related. A 'computer network', or simply a network, is a collection of computers and other related equipment like printers, switches, access points, routers and network storage devices connected together using physical wires/cables or by wireless means. The network is highly available through redundancy and modularity and capable of providing an increased level of service not currently realized. Options with your degree. •Single-fabric multi-service—This technology gives the network administrator the ability to have many different services or networks share the same infrastructure, yet maintain logically separate networks. It provides secure login, customizable playlists, search, advanced player controls, full-screen playback, slide synchronization, viewer questions support, and a secure usage-reporting tool. You can deliver the same content to all signs in the district, such as reminders of testing dates, or deliver different content to different schools.
