Determining Your Networking Requirements > Introduction to Cisco Network Design
enterprise wireless and/or data center/server farms? To meet the daily requirements of businesses, networks themselves are becom- planning and design. Jan 9, Designing the Network Services Infrastructure to Meet Business and Technical . So, when you're planning the number of WINS servers, a good . for an administrator to know the configuration requirements of a remote site. Proven network design and implementation services that drive results for parameters and design a network to meet the challenges of your business With increased IT challenges resulting from the explosion of devices and user requirements, Make the most of your server investment dollars with server consolidation.
So when you are assessed in VET it is about whether you are competent to do the job, as well as having a firm grasp on the knowledge and skills required to do that job, as opposed to traditional curriculum based education settings that are often based on knowledge retention.
You need to demonstrate you are competent in each element of the unit of competency you are studying. You will receive feedback on each assessment task that will inform you whether you are competent or not and how well you are performing. Once competent in all elements of the unit you receive a competency grading. Please refer to the Final Grades table below.
After achieving competency we then grade your performance in the unit; this gives you the opportunity to have the level of your performance formally recognized against industry standards and employability skills. The grading will include the following criteria: You should endeavour to demonstrate a high level of initiative in your approach to installing your system and designing, building and testing your server. Problem-solving in particular will require considerable amount of resourcefulness.
You will also need a basic understanding of networking concepts in general. You should be prepared to research topics to improve your understanding.

You should aim to consistently demonstrate your skills in each of the class exercises as well as in the final assessment task. Document protocols used in the network, including routing protocols used for connectivity between buildings. Step 6 Determine the number of LAN switch ports required currently and projected over the next 24 months for each location.
Even though this is a small manufacturing company, the building may include one or more telecommunication closets called intermediate distribution frames. The closet also serves as the installation location for LAN access layer switches that provide the connection ports for wireless access points, computers, printers and other network hardware your company may use.
The access layer switches will connect to the computer room switches using multi-mode fiber optics. Step 7 Select access layer switches based on your projected growth requirements for network ports and future expectations for wireless network service, voice and video integration and quality of service.
The List of the Steps to Design & Implement a New Network for a Small Manufacturing Company
This approach ensures that network hardware meets the needs of the company and supports the addition of new features without hindering performance.
Plan enough strands of fiber between the access layer and the computer room switches for growth as well as ensuring that the fiber uplinks and switch ports will support bandwidth requirements.
Step 8 Select switches and routers, introducing standards for each layer of the network.
For the access layer, consider standardizing on a chassis based switch for areas of the building where you need to support future expansion and added ports or features. Use smaller switches in other areas. When you create a standard for network hardware, you reduce variations and ease support as staff members are familiar with the equipment.
Network switches and routers must support immediate port requirements and have the ability to expand when new features are introduced. Determine if the manufacturing portion of the network will require switches that tolerate environments that produce higher temperatures or conditions that will require a hardened industrial-based switch. Step 9 Select computer room switches.
Evaluate dual switches designed to support fiber connections from each access layer telecommunication closet.
Plan the port density and speeds to support the servers in a combined distribution and core layer. A dual switch configuration in the computer room provides redundancy and scalability when you use chassis-based switches. As an alternate approach, consider a single enterprise-class switch to reduce cost and support future progression to a dual switch design.
Present both options to the management team, identifying the benefits, risks and costs of each option. If any legacy clients such as Windows NT 4. You also need to look at the physical network. However, if there are a large number of hosts on the subnet or if there are multiple subnets, WINS should be implemented.Building Small Office Network - Part1 - Network Design
In terms of the number of clients, the performance of a physical network can suffer if broadcasts are relied on for name resolution. Implementing WINS can reduce the number of broadcasts on a subnet.
Also, because routers do not forward broadcasts between subnets, WINS should be used to facilitate network access between different subnets.
Planning a network installation | Connecting Up
WINS servers on different subnets can be configured for replication so that clients on one subnet can resolve the names of clients on other subnets. A single WINS server is capable of handling a large number of requests.
The number of WINS servers you implement on a network is dependent on several things, such as the hardware installed on the WINS server, whether or not the network is routed, as well as the number of clients on each subnet. When determining the number of WINS servers required, keep the following points in mind: The number of NetBIOS names typically registered by a WINS client The frequency of name registrations and releases due to workstations being rebooted The speed and availability of the physical links connecting the various networks A single WINS server is capable of handling approximately 10, clients; of course, this is dependent on the amount of NetBIOS traffic that is generated.
It is always recommended that two WINS servers be configured for fault tolerance.
Planning a network installation
You can then configure the two WINS servers as replication partners. When implementing multiple WINS servers, you also need to decide where they should be located. The speed and available bandwidth of the existing network connections have a major effect on where WINS servers are placed.
When designing a DHCP infrastructure, you need to consider the following points: Therefore, the main factors that will influence the number of servers you implement will be the existing network infrastructure and the server hardware. If your network consists of a single subnet, a single DHCP server is sufficient, although you might choose to implement more than one for a high level of availability.
You can also use the Alternate Configuration option, and manually specify the IP address parameters that a client should use if a DHCP server is not available. In terms of the network infrastructure, if the network consists of multiple subnets, routers can be configured to forward DHCP broadcasts between subnets. Or you might choose to place DHCP servers on each of the subnets. In any case, before you implement any DHCP servers on the network, consider the following points: If your DHCP server lacks the hardware and depending on the number of clientsyou might need to implement more than one DHCP server to improve response time for clients.
Implementing a single DHCP server creates a single point of failure. Consider the speed of the links connecting various networks and segments. Because DHCP servers do not share any information, there would be no increase in network traffic. Network traffic on the slow link would actually be reduced because clients can obtain leases locally as opposed to using a remote DHCP server.
Placement of DHCP Servers When it comes time to determine where on the network DHCP servers should be placed, keep in mind that your overall goals are to provide high levels of client performance and server availability. If you're implementing a single DHCP server, it should be placed on the subnet that contains the highest number of clients. Also keep in mind that with a single-server implementation, the network connections should be high speed and the server should be configured with the appropriate hardware.
