Abstract
Methods and systems are provided for controlling elements in a signal path of a communication network to accommodate changes in the rate of a client signal. In particular, during the bandwidth resizing (BWR) portion of ITU-T Recommendation G.7044 Hitless Adjustment of ODUflex(GFP) protocol (HAO), the nodes in the chain along the ODUflex(GFP) signal path change their output rates in parallel such that FIFO over/underflow is avoided in the nodes. Certain embodiments provide mechanisms to synchronize and stabilize the nodes in a verifiable manner.
