I am very new to network. Please help!
Activity Description
Planning is an important aspect with any enterprise network structure. However, planning must encompass several aspects including not only the assessment of the technology required, but also keeping the stakeholders in mind. In a paper, accomplish the following:
What are three (3) key aspects to planning for an enterprise network?
Why does planning help to minimize enterprise network failures?
What redundancy plans can be put in place to help avoid network failures?
Why is it important to give careful consideration to the usability of the systems within the enterprise network?
Length: 5-7 pages (not including title and reference pages).
Explanation / Answer
Planning of a Network design is important for an enterprise before begin an enterprise.
The network should stay up all the time, even in the event of failed links, equipment failure, and overloaded conditions.
The network should reliably deliver applications and provide reasonable response times from any host to any host.
The network should be secure. It should protect the data that is transmitted over it and data stored on the devices that connect to it.
The network should be easy to modify to adapt to network growth and general business changes.
Finding and fixing a problem should not be too time-consuming.
What are the key aspects to plan for an enterprise network?
Network Design connects people, support applications and services, and provide access to the resources that keep the businesses running.
Five Things to Be Considered in Designing a Network
The steps required to design a good network are as follows:
Step 1. Verify the business goals and technical requirements.
Step 2. Determine the features and functions required to meet the needs identified in Step 1.
Step 3. Perform a network-readiness assessment.
Step 4. Create a solution and site acceptance test plan.
Step 5. Create a project plan
THE ARCHITECTURES REQUIRED FOR THE NETWORK DESIGN
An enterprise network must support the exchange of various types of network traffic, including data files, email, IP telephony, and video applications for multiple business units. All enterprise networks must
Support critical applications
Support converged network traffic
Support diverse business needs
Provide centralized administrative control
Enterprise Business Devices
The enterprise network prevents the business from performing normal activities, which can result in a loss of revenue, customers, data, and opportunities. Enterprise-class equipment is designed for reliability, with features such as redundant power supplies and failover capabilities.
Hierarchical Network Design
To optimize bandwidth on an enterprise network, the network must be organized so that traffic stays local and is not propagated unnecessarily onto other portions of the network. Using the three-layer hierarchical design model helps organize the network.
This model divides the network functionality into three distinct layers
Access layer
Distribution layer
Core layer
The access layer provides connectivity for the users. The distribution layer is used to forward traffic from one local twork to another. Finally, the core layer represents a high-speed backbone layer between dispersed networks.
CISCO ENTERPRISE ARCHITECTURE:
The Cisco Enterprise Architectures can be used to further divide the three-layer hierarchical design into modular areas.
Enterprise campus: This area contains the network elements required for independent operation within a single campus or branch location. This is where the building access, building distribution, and campus core are located.
Server farm: A component of the enterprise campus, the data center server farm protects the server resources and provides redundant, reliable high-speed connectivity.
Enterprise edge: As traffic comes into the campus network, this area filters traffic from the external resources and routes it into the enterprise network. It contains all the elements required for efficient and secure communication between the enterprise campus and remote locations, remote users, and the Internet.
Planning for Redundancy
Redundancy is a critical design feature for most company networks.
Implementing Redundancy
The availability of the network is essential to support the business needs. Redundancy is an important part of network design for preventing disruption of network services by minimizing the possibility of a single point of failure. One method of implementing redundancy is by installing duplicate equipment and providing failover services for critical devices.
