A buffer that Net8 uses to place data before transmitting across the network. Net8 sends the data in the buffer either when requested or when it is full. When large amounts of data are being retrieved and when packet size is consistently the same, it may speed retrieval to adjust the default SDU size.
The default is 2048. The SDU size should be set as a multiple of the normal transport frame size. Since the normal Ethernet frame size is 1500, the most efficient SDU size over an Ethernet protocol should be a multiple of 1500.
