<p>Disclosed is a method for resizing a network connection in an optical transport network that supports protection switching. The optical transport network receives a flexible optical channel data unit (ODUflex(GFP)) signal. In addition, between nodes located on a protection path for protection switching, only a link connection resize (LCR) protocol of a hitless adjustment of ODUflex(GFP) (HAO) procedure is performed and a bandwidth resize (BWR) protocol of the HAP procedure is not performed. On the other hand, both the LCR protocol and the BWR protocol are performed between nodes located on a working path.
