Abstract:
There is provided a method for resizing a network connection in an optical transport network that supports protection switching and receives a flexible Optical channel Data Unit (ODUflex(GFP)) signal. In addition, at nodes located on a protection path for protection switching, only a Link Connection Resize (LCR) protocol, except for a Bandwidth Resize (BWR) protocol, of Hitless Adjustment of ODUflex(GFP) (HAO) procedure is executed. On the other hand, both the LCR protocol and the BWR protocol are executed at nodes located on a working path for protection switching.
