A Traffic Analysis per Application in real IP/MPLS Service Provider Network

Abstract

In this work, real traffic of a service provider IP/MPLS network is classified per application using a traffic characterization procedure based on self-similarity. The results of such classification show that the real traffic confirms a high degree of burstness due to high values of the Hurst parameter. These results are used for the proposal of a method of network capacity planning. The major difficulty is the knowledge of the traffic inside the backbone, and this needs to be a self-learning process mainly because every day new service applications are inserting new type if traffic. In this work an ILEC(incumbent local exchange carrier) service provider IP traffic will be classified per application after that applying a self similarity characterization some analysis will be done.

Network Planning Optimization for Multimedia Networks

“…Long time and several recently observations in operating networks confirm that the aggregated traffic in the cores, i.e. the multimedia traffic, has a self-similar and multifractal nature [3,4,5,6,7,8], which results when multiplexing different sources that differ significantly in their finite buffer systems modeling against the traditional Markovian models.…”

IP and 3G Bandwidth Management Strategies Applied to Capacity Planning

“…For a Poisson traffic this value is close to 0.5. Experimental results show that this same parameter in operational networks (Perlingeiro & Ling, 2005;Carvalho et. Al., 2007) has values between 0.5 and 0.95.…”

“…The core idea is that using only some parameters the mathematical calculus can be feasible at real time, as shown in Figure 14. In this case, the tunnels are configured using the self-similarity bandwidth estimators, as described in (Carvalho, 2007). The traffic needs to be marked as the DiffServ and will be injected per tunnel as the auto configuration tunnel selection.…”

“…The above research works verified that the Poisson traffic model is not able to explain the IP traffic dynamics and this implies that the capacity planning tasks for integrated services will need new methodologies. Some models have been used with superior performance to achieve these goals, the self-similar or monofractal model show acceptable results in several situations (Carvalho et al, 2007).…”

Mitigação de problemas de desempenho entre sistemas autônomos com tráfego assimétrico focada na influência na tomada de decisão do BGP

“…Esta comunicação é ponto-a-ponto e peer-to-peer, desta forma a estimação da banda para cada conexão é dada pela definição do próprio CODEC. Este assunto é tratado em (Carvalho et al, 2007), sendo esta condição diferente das estimativas de banda necessárias para o backbone ou núcleo da rede, uma vez que para este último trata-se de tráfego altamente agregado com diversidade de conexões.…”
