A network element comprising a processing system configured to: - control the network element to transmit first data to a first other network element via a first data transfer path from the network element to the first other network element, the first data comprising an Ethernet Operations, Administration, and Management message, - form, at least partly on the basis of second data received from the first other network element, a first limit value indicating smallest of hop-specific data transfer speeds related to the first data transfer path, - control transmission speed of a first data flow transmitted from the network element to the first other network element to be limited on the basis the first limit value, - control the network element to transmit the first data to a second other network element via a second data transfer path from the network element to the second other network element, - form, on the basis of third data received from the second other network element, a second limit value indicating smallest of hop-specific data transfer speeds related to the above-mentioned second data transfer path, and - control transmission speed of a second data flow transmitted from the network element to the second other network element to be limited on the basis the second limit value, wherein the Ethernet Operations, Administration, and Management message represents a request for the second data, characterized in that the processing system is configured to: - control, in response to a situation in which the first limit value is related to a hop belonging to both of the first and second data transfer paths, transmission speed of an aggregate of the first data flow and the second data flow to be limited on the basis of the first limit value, and - control, in response to a situation in which the second limit value is related to a hop belonging to both of the first and second data transfer paths, the transmission speed of the aggregate of the first data flow and the second data flow to be limited on the basis of the second limit value. - control the network element to transmit first data to a first other network element via a first data transfer path from the network element to the first other network element, the first data comprising an Ethernet Operations, Administration, and Management message, - form, at least partly on the basis of second data received from the first other network element, a first limit value indicating smallest of hop-specific data transfer speeds related to the first data transfer path, - control transmission speed of a first data flow transmitted from the network element to the first other network element to be limited on the basis the first limit value, - control the network element to transmit the first data to a second other network element via a second data transfer path from the network element to the second other network element, - form, on the basis of third data received from the second other network element, a second limit value indicating smallest of hop-specific data transfer speeds related to the above-mentioned second data transfer path, and - control transmission speed of a second data flow transmitted from the network element to the second other network element to be limited on the basis the second limit value, - control, in response to a situation in which the first limit value is related to a hop belonging to both of the first and second data transfer paths, transmission speed of an aggregate of the first data flow and the second data flow to be limited on the basis of the first limit value, and - control, in response to a situation in which the second limit value is related to a hop belonging to both of the first and second data transfer paths, the transmission speed of the aggregate of the first data flow and the second data flow to be limited on the basis of the second limit value. <EOS>
