  • Dec 2011
Cellular backhaul networks carry user's traffic within encrypted tunnels. With tunneled traffic, the application classifier cannot identify the underline TCP/UDP connections and cannot use any IP packet header information. Yet, some statistical properties can be considered in this case too, such as: volume per tunnel, tunnel durations, inter-packet...

On the Trade-off Between Spectrum Efficiency with Dedicated Access and Short End-to-End Transmission Delays with Random Access in DVB-RCS2
Conference Paper
Full-text available
  • Sep 2013
This paper analyses the performance of TCP over random and dedicated access methods in the context of DVB-RCS2. Random access methods introduce a lower connection delay compared to dedicated methods. We investigate the poten- tial to improve the performance of short flows in regards to transmission delay, over random access methods for DVB- RCS2 th...
