摘要
In this letter: we assess the scalability of a path computation flooding (PCF) approach to compute optimal end-to-end inter-domain paths in a path computation element-based multidomain network PCF yields a drastically reduced network blocking probability compared to a blind per-domain path computation hut introduces significant network control overhead and path computation complexity In view of this, we introduce and compare an alternative low overhead PCF (LoPCF) solution. From the obtained results, LoPCF leads to similar blocking probabilities to PCF while exhibiting around 50% path computation complexity and network control overhead reduction.
