Summary: Final Project Milestone Two: WAN Technology Requirements

Routers and switches will be utilized to route network signals to all areas of this large network. Telephony systems will be introduced to serve the VOIP located at each location to assist with communication needs. Wireless technologies will also be needed to assist with mobility and other devices such as printers, laptops, fax machines, etc. Lastly, a physical firewall will be enforced at each location to protect the network from internal and external intruders.

When designing a WAN, numerous factors must be considered. Organizations attempting to connect multiple factories or offices and remote personnel must take into account a number of variables that will impact overall costs and network functionality. When designing and implementing wide area networks (WANs) that integrate voice, video,

Verizon’s T-1 link will be used for the network connection throughout the building. Cisco 4500 series switches will be used in the setup of 240 ports which will be more than enough for the 10/100/1000 baseT Ethernet communication, each switch will have a location in the a server room on each floor. Virtual Lans in the switches will give a OSI layer 2/3 container for every one of the network subnets in the table shown above; this will make sure that each host will have a small amount of interference with other hosts on the network. Active Directory is what will be used in the network, this will be used to authenticate and authorize users through a single sign on service which will secure UMUC’s vulnerable data. UMUC’s network will need a Dynamic Host Configuration Protocol which will be a simply way manage the IP addresses across its network. Microsoft DHCP will also be used because of the vulnerability of a fake DHCP server being able to cause network problems with a authorized Dynamic Host Configuration Protocol. DHCP will broadcast to for a discovery signal, and the relay service will then start up all of the Cisco 4500 series switches so that the DHCP discovery packets to go out to Virtual LAN areas. Layer 2 core network service is going to be broadcasted by the Cisco series 4500 switch which will be in the first floor’s IT closet; doing this will stop the routing decision delays throughout the network

Because of a staggering influx of Internet business, the network administrator’s task is to boost network performance and availability as much as possible. The company also wants a network design that’s easy to reconfigure and change because workgroups form and disband frequently, and their membership changes regularly. All computers must share sensitive data and control access to customer files and databases. Aside from the customer information and billing databases, which run on all servers, employees’ desktop computers must run standard word-processing and spreadsheet programs. Use the following write-on lines to evaluate the requirements for this network. After you finish, determine the best network topology or topology combination for the company. On a blank piece of paper, sketch the network design you think best suits EBiz.com’s needs. Remember: High performance and easy reconfiguration are your primary design goals!

These factors will impact on the network costs, speed, infrastructure, and functionality. When designing this Local Area Network (LAN) for DesignIT, there is also need to consider the network requirements. The network should integrate sound, video, synchronous, as well as asynchronous data. When designing the LAN network, the organizational goals of DesignIT should be factored in the LAN design. I will also pay attention to network throughput, line charges, security, and the integration of newer technologies in the future. When designing a LAN network, some issues must be considered, one of these issues is the organization’s short, medium, and long term goals. Several factors to be considered include the network equipment, user applications, end-user equipment (workstations), and connectivity to the internet.

Connect Main store to new buildings with Wide Area Network (WAN) and Local Area Network (LAN)

Since one office is in the center of the WAN, it would be the most logical location for the main server headquarters. This main location would be home to six servers, two of them being print servers and the other four each hosting their own specific applications to all of the workstations in the network. The first of the four servers would hold the business management applications needed by any of the accountants or human resource teams. The second would hold the medical managing software that would hold all patient information, insurance, and bills that could be accessed from any of the 5 office locations in the network for both doctor and patient convenience. The third will be used to host a web server and the final system will be used as a domain controller that will manage the users and groups on the network.

As a business grows, it might expand to multiple offices across the country and around the world. For a growing business firm, limited number of offices is typically not adequate. With adequate capital and personnel, many business firms desire to set up multiple offices to attract different areas of customers (Lock, 2007). To keep business running efficiently, the employees working in those locations need a reliable, secure and fast way to share information across computer networks. With the help of networking technology, one firm can install a network so that all the employees and customers of separate offices can communicate, and access

The IT department has been given a budget of $25,000 to complete the project. The budget includes the equipment, the installation, all software and licensure used to operate and maintain the VoIP throughout all three (3) buildings. An estimate is required if outsourcing to a local installation company is decided upon. The estimate must be approved by the President or CEO of the company before any work is performed or started.

Security modules (firewalls, anti-virus servers) will reside within the WWTC network that will provide intrusion detection and protection from malicious cyber-attacks. They will also filter the traffic entering or exiting the intranet. Aggregate networking devices such as routers and switches will provide connectivity to all users within the organization. The server farm will provide the local domain services to the staff and allow users to access necessary resources like data and video. Voice services will also be provided by Cisco Call Managers. Once complete, the network will have global reachability and be modularly engineered. Provide scalability in the event that the organization expands is a focal point in order to eliminate the need to completely reconfigure the network in the foreseeable future.

The project will guide you through the process of designing a network for small business, big business and for your own private or public network. Our type of this sort of the network includes four to twelve computer (laptop), one or two servers, multiple switches, two to four routers, some networked printers and access to other networks especially the internet for a user.

To allow the regional offices to pass traffic securely a GRE IPsec tunnel will be created between offices. This will allow all data to be encrypted prior to being sent out to the internet. This will prevent unauthorised reading or manipulation of sensitive data. The UK office will have two tunnels, one to each branch office. In order for the remote branches to communicate with each other their traffic will pass through the head office. The initial part of the configuration is the addition of GRE tunnels between the offices. These will be based on /30 subnets within the 192.168.0.0 range. Ethernet allows packets of up to 1500 bytes to pass through it. As the GRE header adds an additional overhead to each packet Cisco recommend configuring the Maximum Transmission Unit (MTU) to 1400 bytes. An additional aid is to add the TCP adjust-mss 1360 which keep the TCP SYN packets small enough to pass across the tunnel.

For secure site-to-site connectivity, the Barracuda Link Balancer comes with a built-in IPsec VPN gateway. In case of link failover and failback, VPNs fail over to available links and maintain traffic priorities to ensure uptime for critical organizational services across the WAN. MPLS links

I choose the devices needed for the new implementation: Cisco Catalyst 6500 router and 2800 series four switches will be utilized. Here is the cost of effective access switches that are capable of VLAN, DTP, DHCP, RSTP, PoE, and furthermore, price can range from $1,400-$3,500 dollars each. These switches offer integrated security including network control and quality service, they also offer redundancy to provide and deliver intelligent services for a networking edge. Therefore, they include flexibility in the routing series as increased port density which could induce a rapid growth in networks without any additional cost at any time. However, the more capacity a device may have the more beneficial it will be to the administrator user, when setting up any secure measures throughout the configuration process of vlans and networks. The network accessibility will be ensured throughout the provision of redundancy of routers throughout the xACME network on each site or trade school. Although, optic fiber cables will be used to connect all layer 2 and 3 switches and servers, spanning tree protocol will be set on switched to address to eliminate any bridging loops from entering into any

Increasingly networks are not just confined to the office but are being adopted so that they allow home/remote working that supports changing business needs.
