Implementing link aggregation

The Prosilica GX series cameras offer two Gigabit Ethernet ports for image data

transfer and control. Users can connect one or both ports on the Prosilica GX to

Ethernet adapter ports on a host computer. The dual port approach requires the

host computer to configure a Link Aggregate Group (LAG). A LAG configuration

combines multiple Ethernet ports into a single data channel.

When is LAG needed?

Connecting both ports increases the available bandwidth to 240 MB/sec. This is

beneficial for the following cases.

• Need to use high(> 8 bits) bit depth pixel formats.

• Highest frame rate is needed.

The following examples show how to determine bandwidth consumption. If the

value is greater than 125 MB, LAG is required.

Example 1:

GX1050 camera using Mono8 pixel format and outputting 100 fps

Bandwidth usage = Resolution x Pixel format x Frame rate

= 1024 x 1024 x 1 (1 byte for Mono8) x 100

~ 105 MBps
