Cisco Enterprise Designs

The Cisco Enterprise Designs can be used to additionally distribute the three-layer hierarchical plan into sectional areas. The modules symbolize different areas that have dissimilar physical and logical connectivity. They describe where dissimilar functions happen in the network. This modularity allows elasticity in network scheme. It greatly simplifies implementation as well as troubleshooting. The three most important areas in modular network design are the following:
Enterprise Campus: This area encloses the network components that are necessary for independent operation inside a single campus or branch office location.
Server Farm: An element of the enterprise campus. The data center server farm safeguards the server assets and offers redundant and consistent high-speed connectivity.
Enterprise Edge: As data inside the campus network, this area screens traffic from the exterior resources and routes it inside the corporate network. It includes all the components required for effective and safe communication among the enterprise campus, distant locations, distant users, and the web.
Cisco Enterprise Architectures design advantages
It builds a predictable network with specific boundaries among modules. This design offers clear differentiation points so that the network architect sees precisely where the traffic originates and where it goes.
It simplifies the design job by making every single module autonomous. The designer can now concentrate on the requirements of each network area separately.
It delivers scalability by helping enterprises to add new units easily. As network complexity grows, the network administrator can add new network appliances.
It allows the network designer to add more services without altering the underlying network design.
Big network design tasks are usually divided into three different steps:
1. Classifying the network requirements.
2. Describe the existing network.
3. Plan the network topology.
Classifying Net Requirements
The network designer is working closely with the client to document the requirements of the job. Usually this procedure is separated into two categories:
Business goals: Emphasize on exactly how the network can improve the business
Technical requirements: Emphasize on how the new equipment is implemented within the net.
Describing the Existing Net
Data about the existing network are gathered and analyzed. It is essential to match the functionality of the current network with the distinct objectives of the new project. The network designer controls whether any current unit, component, and protocols can be used again as well as what new hardware components and protocols are necessary to complete the project.
Planning the Net Topology
A good strategy for network design is the top-down approach. In this method, the network services are identified first, and after that task the net is designed to support them.
Once the network design is complete, a thorough test is performed. This method guarantees that the new plan functions normally before it is carried out.
