Abstract
An Optical channel Data Unit flex (ODUflex) resizing method, node, and network include determining that the ODUflex needs resizing, wherein the ODUflex is configured in the network on a current path between the node and a second node in the network; when the resizing is a decrease, reducing a size of the ODUflex by i) a resize decrease operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation; and, when the resizing is an increase, increasing a size of the ODUflex by i) a resize increase operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation. The method provides hitless resizing without using ITU Recommendation G.7044/Y.1347 (10/11) and can perform the reducing or the increasing changing bandwidth of the ODUflex by approximately 100 G in less than a second.
