Configuring Significant Change Thresholds

PNNI topology state elements (PTSEs) would overwhelm the network if they were transmitted every

time any parameter in the network changed. To avoid this problem, PNNI uses significant change

thresholds that control the origination of PTSEs.

Any change in administrative weight (AW) and cell loss ratio (CLR) is considered significant and

triggers a new PTSE.
