The demand for wireless access in campus continues to grow and the network is being expanded to offer higher capacity and greater coverage to the campus. In order for us to plan for this expansion, it is important that we understand current usage patterns that we understand where, when, how much, and for what our wireless network is currently being used. This paper describes the methodology we employed to collect data on usage, and presents the results of our analysis. Although our wireless network is small at the present time, a description of our approach to this analysis will be useful to others planning similar studies. In this report we will start from working basic router configuration then covering the Routing technologies required to route data between branches. After that we have implement Vlans, WAN and Frame-relay is considered a good choice because it connects multiple location using single interface of router and reduce the hardware costs.For Internet connectivity we are also using frame relay.
Description Of The Project
A campus network, campus areanetwork, corporate area network or CAN is a computer network made up of an interconnection of local area networks (LANs) within a limited geographical area. The net working equipments (switches, routers) and transmission media (optical fiber, copper plant, Cat5 cabling etc.) are almost entirely owned by the campus tenant / owner: an enterprise, university, government etc
College or university campus area networks often interconnect a variety of buildings, including administrative buildings, academic buildings, university libraries, campus or student centers,residence halls, gymnasiums, and other out lying structures, like conference centers, technology centers, and training institutes. Campus networking is rightly perceived by most colleges and universities to be one of the most important issues facing them at present. A campus network is far more tan just a physical infrastructure, and planning and building a campus network really means developing an entirely new information environment that will have a profound impact on almost every aspect of campus life. In building net works, campuses are engaged in a change process that is strategically essential to their very nature and existence. This article offers some advice to administrators and faculty about things to consider as they engage in planning, building, and managing campus networks in small college environments.
A large campus with groups of buildings can also use WAN technology to connect the buildings. Although the wiring and protocols of a campus might be based on WAN technology, they do not share the WAN constraint of the high cost of bandwidth. After the wire is installed, bandwidth is inexpensive because the company owns the wires and there is no recurring cost to a service provider. However, upgrading the physical wiring can be expensive.
Consequently, network designers generally deploy a campus design optimized for the fastest 0functional architecture that runs on the existing physical wire. They might also upgrade wiring to meet the requirements of emerging applications. For example, higher-speed technologies—such as Fast Ethernet, Gigabit Ethernet, and ATM as a backbone architecture—and Layer 2 switching provide dedicated bandwidth to the desktop.
In our project For security purposes, our wireless network consists of a virtual network, existing on a separate subnet from the rest of the campus. Packets sent from and to wireless devices travel on the same physical network as normal campus traffic. Upon connection, wireless devices on the network are assigned internal IP addresses by a DHCP server. All wireless traffic is then sent to the campus router, which routes it either to the internet or back onto the campus network in the normal subnet. This prevents unauthorized wireless users from connecting directly to campus servers and the internet.
WAN communication occurs between geographically separated areas. In enterprise networks, WANs connect campuses. When a local end station wants to communicate with a remote end station (an end station located at a different site), information must be sent over one or more WAN links. Routers within enterprise networks represent the LAN/WAN junction points of a network. These routers determine the most appropriate path through the network for the required data streams. WAN links are connected by switches, which are devices that relay information through the WAN and dictate the service provided by the WAN. In our project for the WAN connectivity i.e. to connect the campuses across different regions we have configured frame relay to provide the interconnectivity between the campuses.
OBJECTIVES:
· Redesign the IP addressingscheme.
· Increase the bandwidth of the Internet connection to support new applications and the expanded use of current applications.
· Provide a secure, prívate wireless network for students to Access the campus network and the Internet.
· Providean open wireless network for visitors to the campus to Access the Internet.
· Provide security to protect the Internet connection and internal network from intruders.
· Use network management tolos that can increase the efficiency and effectiveness of the IT department.
