Dear Sir: At application level, there is an parameter:packetsize_. At RTP level, there also is such a parameter. I find the size in the tracing files. I do not know what this parameter means? Are they equal to each other? Are they embrace the overhead of protocol? Thanks Zhang lei __________________________________________________ ��ӭʹ�ý���������ѵ����ʼ�ϵͳhttp://www.990.net
