This paper summarizes latest works of Telematic,
Networks and Services research group (TNS) of Public University
of Navarra in the topics of FIERRO thematic network. Last two
papers sent to major conferences are addressed
First work shows how self-similar traffic can be generated
using Perlin Noise, an algorithm commonly used to generate
2D/3D noise for natural looking graphics. 1-dimension Perlin
Noise can be interpreted as network traffic and used to generate
long range dependent traffic for network simulation. The algorithm
is compared to more classical approach Random Midpoint
Displacement showing at traffic generated is similar but can be
generated continuously with no fixed block size.
Second work presents two novel cloning schemes for video
delivery in OBS networks that dramatically improve user perceived
content quality. These schemes take into account the
special characteristics of compressed video traffic. Analytical and
simulation results show up to 40% QoE improvement without
a substantial increase in the overall network traffic and without
increasing the number of bursts in the network. The results show
the strong dependency of this novel cloning scheme on the video
traffic structure due to the coding mechanisms. [--]
