For more information about managing network bandwidth when using multiple cameras on a single
network path, see the "Basler Network Drivers and Parameters" section in the camera User’s
Manual.
Network Switch Issues
When selecting GigE network switches for use in the type of network described above, there are
several issues you must keep in mind.
First is that the switch must be able to handle large packets (also known as "jumbo packets" or
"jumbo frames"). The typical maximum packet size on Ethernet devices used in the past was 1.5
kB. With newer "jumbo frame capable" devices, the maximum packet size can be up to 16 kB.
Basler GigE cameras and the recommended network adapters (see Section 4.5.1 on page 19) can
both handle jumbo frames. For maximum network efficiency, your camera should be set to use the
largest packet size that your network can handle. If you select a network switch that can only handle
a small packet size, you will limit network efficiency.
A second issue involving the network switch is buffer capacity. In the situation where multiple
cameras are attached to a switch, the switch must have enough buffer capacity to hold the incoming
data from the cameras while it transmits the data out in an orderly fashion on the single outgoing
line. In general, more buffer capacity is better.
Computer Data Bus Issues
If you are connecting multiple cameras to your host computer, either through direct peer-to-peer
connections or through network switches, you must be aware of the data bus type used in the
computer. The PCI bus typical of older PCs is theoretically capable of handling 132 MByte/s of data.
But in practice, the capacity of the PCI bus is lower and the bus bandwidth is shared by the network
adapter and many other devices installed in the computer. To ensure adequate bandwidth on the
computer’s data bus, use of a computer with a PCI express data bus is recommended.
