The availability of high capacity switches gives customers the advantage of building its campus with a high performance, high reliability networksif correctly by following the approaches to network design. Unfortunately, some alternative approaches to network design can result in a network that has a low performance, reliability and manageability.In this documentation we describe hierarchical vision of a modular design called multi-layer design. This verifies documentation designs of the Enterprise Campus and Enterprise Data Center network infrastructure.

Designing Basic Campus and Data Center Networks


Campus Design Considerations

When an enterprise grows to include branch offices, e-commerceservices, or global operations, a single LAN network is no longer sufficient to meet its business requirements. Wide-area network (WAN) access has become essential for larger businesses today.
For this reason the design of a corporate campus is divided into three parts:

Network application characteristics:

The characteristics of the implementation of the network and needs influence the design inmany ways.

Applications that are critical to the organization and network demands of these applications, determine the traffic patterns of the company within the Enterprise Campus Network, which influence the use of bandwidth, response times, and the election the transmission medium.

The different types of result of the implementation of communication for different network applications. In thefollowing sections review four types of communication on the application:

- peer to peer: applications used in daily work for the job, and what are the messages, quality of service and file sharing.

- local client-server: The term client / server is originally applied to software architecture that describes the transformation between two or more programs,implementation and support services. These applications must comply with server traffic should be less crowded than the LAN. For 80/20 this is the law that says 80 percent of traffic is LAN and 20 segments.

Client-Server Farm: The use of a server requires a network infrastructure that is highly resistant (including security) and redundant (providing high availability)and that provides adequate performance. High-end switches with wireless LAN technology faster, such as Gigabit Ethernet, are usually deployed in that environment. Applications for this implementation are: Organizational mail, file servers, database servers.

Client-Server Enterprise Edge: Typical applications for enterprise edge technologies based on web. Examples ofthese types of applications, such as external mail and DNS servers and public web servers can be found in any organization.
