9. Network and System Management

This chapter describes the tools for managing the network traffic to optimize its performance and

the system management features of the wireless VPN firewall. The chapter contains the

following sections:

• Performance Management

• System Management

Performance Management

• Bandwidth Capacity

• Features That Reduce Traffic

• Features That Increase Traffic

• Use QoS and Bandwidth Assignment to Shift the Traffic Mix

• Monitoring Tools for Traffic Management

Performance management consists of controlling the

traffic through the wireless VPN firewall

so that the necessary traffic gets through when there is a bottleneck. You can either reduce

unnecessary traffic or reschedule some traffic to low-peak times to prevent bottlenecks from

occurring in the first place. The wireless VPN firewall has the necessary features and tools to

help the network manager accomplish these goals.

Bandwidth Capacity

The maximum bandwidth capacity of the wireless VPN firewall in each direction is as follows:

• LAN

side. 8000 Mbps (eight LAN ports at 1000 Mbps each).

• W

AN side. 1000 Mbps (one active WAN port at 1000 Mbps).

In practice, the WAN-side bandwidth capacity is much lower when DSL or cable modems are

used

to connect to the Internet: The typical traffic rate is 1.5 Mbps. As a result, and

depending on the traffic that is being carried, the WAN side of the wireless VPN firewall is the

limiting factor for the data rate for most installations.
