Network architecture
In the current business climate, organizations are looking for techniques to enhance customer relationships, accommodate a mobile workforce, and increase productivity. In addition, companies are looking for ways to integrate emerging technologies such as wireless, virtualization, video, unified communications, and a vast number of application-level business solutions into their enterprise. These challenges create the need for a more flexible and dynamic network architecture.
Most network infrastructures are separated into three IT groups:
- Data center: Servers and storage networks
- Network: Routing, switching, security, and wireless WAN
- Applications: Voice and video
Each group has its own experience, budget, and challenges, which naturally create silos. However, for businesses to work more effectively, they must break down those silos and better leverage their experience in IT.
