• Infrastructure Mode: Wireless devices can communicate
with each other and with a wired network
• Wireless Access Point (AP): Connects wireless devices to a
wired network
• Basic Service Set (BSS): One AP and the set of wireless
devices connected to it
– Identified by BSSID
• Extended Service Set (ESS): Two or more interconnected
BSSs that form a single network
– Identified by SSID
Wireless Network Building Blocks

Wireless Network Architecture

8. 8
• Routes traffic between internal devices and outside
networks, joining two networks together
– NAT, DHCP, security, encryption
Gateways

9. 9
• Can have many functions:
– Monitoring and surveillance
– Firewall and traffic filtering
– Traffic encryption and
decryption
– Network connection sharing
– Data caching
– Anonymity
• Typically deployed:
– At the edge of a LAN
• Services users within the LAN,
including those using VPN to
tunnel in
– In the cloud
• Wider visibility and coverage for
all employees
• Popular vendors include:
– Blue Coat, Cisco, Zscaler, F5
Proxies

• Uncover aggregate trends
• Data collected every 5 minutes
– Metrics collected from OS:
• Link speed
• Wireless signal quality
– Metrics collected from network probes:
• Gateway, proxy and VPN loss and latency
• Delay and forwarding loss
• Tip: Deploy an Enterprise Agent at the proxy location to
monitor the path from proxy to destination

• Troubleshoot individual users’ issues
• Data collected every time user visits a monitored domain in
a monitored network
– Web and network performance in addition to network topology
