NetScaler SD-WAN Center provides a central view of bandwidth statistics data polled from different sites in your SD-WAN network.
In the NetScaler SD-WAN configuration, traffic flowing through the virtual paths is classified as belonging to realtime, interactive, or bulk class types. The classes are predefined, but you can customize these classes and apply rules to them. For more information, see Customizing Classe and Rules by IP Addess and Port Number.
Using NetScaler SD-WAN Center, you can view, along with the basic bandwidth statistics, the bandwidth consumed by applications belonging to these class types at each site, path or WAN link level.
To view bandwidth statistics:
In NetScaler SD-WAN Center, navigate to Reporting > Sites, and in the timeline control select a time period.
You can select and view reports of a particular time frame by using the timeline controls. For more information, see, Timeline controls.
You can also create, save and open report views. For more information, see, Manage views.
You can view the following metrics:
- Bandwidth: Total bandwidth consumed by all packet types. Bandwidth = Control Bandwidth + Realtime Bandwidth + Interactive Bandwidth + Bulk Bandwidth. For example, in the above screen shot, at SITE2, Bandwidth = 1120.99+166.61+117.21+810.78+26.40
- Available Bandwidth: Total bandwidth allocated to all the WAN links of a site.
- Control Bandwidth: Bandwidth used to transfer control packets that contain routing, scheduling, and link statistics information.
- Permitted Bandwidth: Bandwidth available for transmitting information.
- Realtime Bandwidth: Bandwidth consumed by applications that belong to the realtime class type in the NetScaler SD-WAN configuration. The performance of such applications depends to a great extent upon network latency. A delayed packet is worse than a lost packet (for example, VoIP, Skype for Business).
- Interactive Bandwidth: Bandwidth consumed by applications that belong to the interactive class type in the NetScaler SD-WAN configuration. The performance of such applications depends to a great extent upon network latency, and packet loss (for example, XenDesktop, XenApp).
- Bulk Bandwidth: Bandwidth consumed by applications that belong to the bulk class type in the NetScaler SD-WAN configuration. These applications involve very little human intervention and are mostly handled by the systems themselves (for example, FTP, backup operations).
