Optical Burst Switched (OBS) networks may
become a backbone technology for video-on-demand
providers. This work addresses the problem of dimensioning
the access link of an ingress node to the optical
core network in a video over OBS scenario. A video-ondemand
provider using an OBS transport network will
have to deliver traffic to a set of egress destinations. A
large part of this traffic would be composed of video
streaming traffic. However, in a real network there would
be also a fraction of non video traffic related to non video
services. This work studies the decision whether it is better
to gather all traffic to the same destination in a joint burst
assembler or separate video and general data traffic on
different burs assemblers. The later may increase burst
blocking probability but also allow for better tuning of
OBS parameters that help improve video reception quality.
Result show that this tuning of parameters is not enough
to compensate the drop probability increase and thus it is
better to aggregate video and general data traffic.
