- Abstract
- We propose a novel inter-layer path control mechanism in a PCE-VNTM cooperative multi-layer networks (MLN). For this, we define a novel FA-LSP aware PCE which only reports and manages a forwarding adjacency-label switched path (FA-LSP) state. In our scheme, the FA-LSP can be distinguished from the pure higher-layer TE link more and accurately controlled with a network policy. We worked out the methodology and conducted a simulation in terms of the setup delay and the control message overhead under various conditions. Our results indicate that, compared with other representative models, it provides the lowest setup delay of about 300 ms with a 50% reduction in the overhead.
