QoS provisioning by novel parallel LSP based routing/signaling protocol in GMPLS network

In this paper, we have developed the new algorithm based on parallel Label Switched Path (LSP) generation using a quantized threshold for reducing the blocking probability by efficiently using the available WDM network resources on the basis of weighted routing/signaling. We suggested three different models with various levels of wavelength conversion at IP/MPLS router for implementing the algorithm. We proposed the measure of reservation factors for the quantized parallel λLSP for each model. The reservation factor ratio comparative graph shows the effectiveness of the algorithm. Further the QoS routing for the purposed algorithm by measuring blocking probability of each model and the effect of o-e-o conversion is investigated against the fixed model. The improvement has been shown over the existing models.
