Abstract
Provided are a device unit, a node device, and a method and a system for automatically adjusting a tunnel bandwidth. The device unit includes: a client side element, configured to dynamically adjust The quantity of the first timeslots according to a bandwidth of a received data service before the received data service is mapped to an Optical Channel Data Unit (ODU) tunnel; a line side element, configured to configure, according to the quantity of the first timeslots adjusted by the client side element, The quantity of the second timeslots matched with the first timeslots; a tunnel managing element, configured to adjust, according to the quantity of the first timeslots and the quantity of the second timeslots, the quantity of unblocked ODU tunnels between the client side element and the line side element, wherein unblocked ODU tunnels after the adjustment carry the data service. When the bandwidth of the received data service increases or decreases, the device unit of the present disclosure flexibly controls usage of an ODU0 timeslot in an ODU of each stage, and does not need to use a complicated ODUflex frame format, thereby meeting the requirement of automatically adjusting the bandwidth without using ODUflex.
