Abstract
A remote management controller may include a video redirection device and a processor. The video redirection device may be configured to: obtain multiple separate slices of video data output from a video graphics controller; calculate at least one value correlative to each of the multiple separate slices of video data; and if the calculated value for any portion of any of the multiple separate slices differs from a value for a previously obtained corresponding portion, update a table associated with an image related to a remote system with the calculated value, process the portion of the slice into a network packet, and move the network packet to one of multiple network buffers. The processor may be configured to: allocate the multiple network buffers; and facilitate transmission of the network packets loaded into the network buffers to the remote system.
