The Enterprise Network is the essence of the business world. The key requirements for enterprise networks: availability, performance, scalability, and security.
The requirements of an enterprise network can be stringent since critical applications need to be accessible at all times, e-mails need to get through, phone networks need to operate at all times, while providing enough bandwidth for all critical and non-critical applications in the organization.
Security is also a key element in an enterprise network. The network should protect the data within the network while keeping out unwelcome traffic from external sources. At the same time, the network should be protected from virus attacks and other unwarranted issues like hacking, intellectual property theft, etc.
Enterprise Networks support business-critical applications and their attendant computing resources such as mainframes, servers, and server farms. Typical applications range from financial and human resources applications to e-commerce and business-to-business (B2B) applications. In addition to the server farms that support business applications, some server farms are used to support network operations and network-based applications.
Enterprises often benefit from the integration and port concentration that chassis-based routers/switches offer. High-bandwidth backplanes among blades allow faster connectivity among many users.
