Dear everyone, If I send a file with size of 15Mb using FTP on TCP, how can I know the complete time of the file transfer? Are there some flags to identify the complete time in the tcp header or in the trace file in NS? Yours, Yuan --http://www.eyou.com --�ȶ��ɿ�����ѵ������� �����ʼ� �ƶ���ǩ �������� ����洢...����δ��
