Networking Requirements
Figure 1 shows
the original network in the university's main campus. Core switches
manage wired users, and independent ACs manage wireless users.
Users in different
areas of the main campus can access the campus network and connect
to the Internet through the campus network. Wired users use 802.1X
authentication and wireless users use Web authentication to access
the network.
The following
figure shows only the network deployment for teaching and office areas.
The network deployment for other areas is similar and is not shown
in the figure.
- The network provides
the Voice over Internet Protocol (VoIP), network printer, and multimedia
services.
- Users in branch campuses
can access the main campus network through the Intranet.
- Users outside the campuses
can access the main campus network through the Internet.

The service deployment on
the current campus network faces the following problems:
- As the population in the
university grows, a large number of wireless users demand for wireless
services. The wired and wireless networks are separately deployed
and difficult to manage. The university demands for the wired and
wireless convergence to simplify network management and improve network
operation and maintenance (O&M) efficiency.
- As various network services
develop in the campus and users need to access the network during
moving, network information security becomes more important. The university
desires the classification of access user roles to ensure that service
policies and network experience are consistent wherever users go.
- The university has a large
number of network devices and needs to frequently adjust network services.
Network administrators need to modify configurations or upgrade versions
on devices one by one to change a service, requiring heavy and trivial
workload. The university desires the centralized configuration, management,
and maintenance of network access devices.
- When a network fault occurs,
network administrators cannot detect or troubleshoot it quickly, affecting
user experience. The university needs a real-time network quality
monitoring mechanism to reduce the impacts of network faults.
The university intends
to deploy an agile network to simplify network deployment and configuration,
improve user experience, and improve O&M efficiency.
