Application Visibility


#AirheadsConf

Overview


#AirheadsConf

Application Visibility: by Destination


#AirheadsConf

8.0 - AppRF Report

• Top destinations and applications

• Top applications broken down by device type, WLAN, role

• Detailed section for one or more users


#AirheadsConf

8.0 - AppRF Visualization

• AppRF overlay for clients

• Identifies clients contributing to the selected application.

• TunableThresholds


#AirheadsConf

8.0 – UCC (Lync, Jabber….)

• Dashboards Identify call quality issues and correlate with client health

• Lync overlay with historical view of calls

• Lync Mobility trail to track historical call sessions


#AirheadsConf

UCC Dashboard

• Call Volume by protocol: SIP, Lync, Jabber


#AirheadsConf

UCC Dashboard

• Calls broken down by device type

• Identify the device types having the worst call quality


#AirheadsConf

Dashboard to Diagnostic page


#AirheadsConf

Call Details

• Selecting a call gives details like jitter, delay for the call.

• The red icon shows the point at which the client roamed during the call..

RF Visualization


#AirheadsConf

VisualRF in HTML5

Improved navigation


#AirheadsConf

VisualRF in HTML5

• Floorplan with APs/Clients and relation lines


#AirheadsConf

VisualRF – Heatmaps & Overlays

• Heatmap


#AirheadsConf

VisualRF – Floor Upload Wizard


#AirheadsConf

Channel Overlay

• Identify Overlapping Regions

RF Capacity


#AirheadsConf

RF Capacity

2 radios were “heavily utilized” 80-100% of the time.

(“Heavily utilized” is 80%+ utilization).

(Only “on time” is considered. That is, blocks of time the radio is doing something, not the middle-of-the-night).

UI


#AirheadsConf

All Graphs in 7.7 Now HTML5

Graphs in AirWave 7.6 and earlier were Flash-basedAll graphs in AirWave 7.7 are converted from Flash to HTML5


#AirheadsConf

All Graphs in 7.7 Now HTML5

By clicking on a graph, can then zoom in/out, pan, and hover (to get values for each point)


#AirheadsConf

8.0 UI Improvements – Views

• Select columns and filters to display the desired set of views


#AirheadsConf

UI Contd.. – Simpler Modify Devices

• Easy to use UI for Modify Devices

Scalable Clustered Architecture in 8.0


#AirheadsConf

AirWave 8.0 - Multi-server Architecture

Scale to 20,000 APs

• No architecture choice will prohibit > 20,000

• Up to that limit, add another server, get another increment of capacity (symmetric arch)

Single Virtual IP from perspective of controller/VC

• Controllers/VCs need be configured with only a single AMP IPaddr

Failover without human intervention

• Failover transition lasts 10min or less, during which time data collection may be interrupted

• Only data loss might be up to 1hr of client session data; no other data loss

• Simple process to re-introduce repaired server to cluster (or add another server)

Can still run on a single server
