   hom much data (size) can i sent on Csocket at a time
  hi, at a time how much amount of data can i sent on CSocket.   thanx 
  Depends on what you mean by "at a time" as well as the underlying operating system, protocol implementation, hardware, device drivers, etc.edit: grammar   [edited by - SiCrane on February 8, 2004 5:55:29 AM];  ... network state, remote system''s OS, remote system''s protocol implementation, remote system''s hardware, remote system''s device drivers, the speed at which the remote system actually reads the data you sent, etc. ;  If you are really looking for a number the maximum packet size of an ethernet packet is 1500 bytes.  ;  That doesn''t really help him because data is usually buffered by the underlying protocoll until it can be send. MTU size is irrelevant unless you are (for example) sending out UDP packets where you have to restrict the packet size. Also, the MTU size doesn''t say how fast the data is actually send.
