[c-nsp] effect of different packet size? and how to ensure video packet are not lost during other TCP communication

[Farhan Aleem]

I got two general conceptual question which are not specific to
cisco.But i need to find out about these. Thanks in Advance. hope that
it is not disliked to but general question

What will be the effect if the packet size is changed. like  using FTP
and video confrencing which uses UDP. If packet size is varied then wt
are the possible results as the link bandwidth is same transmissino
rate is same.


And how it can be  ensured that  video packet are not lost during
other TCP communication like ftp on the link shared for ftp and video
confrencing...?
