Abstract: A method and relates apparatuses for detecting a link status on an Ethernet connection where at least part of a transmission path is implemented via a wireless connection, the first wireless link device performing: establishing a wireless connection to a second wireless link device; establishing a wired connection to a first Ethernet-compliant network device; sending a remote link status message indicating the status of the wired connection between the first wireless link device and the Ethernet-compliant network device repeatedly to the second wireless link device; monitoring a remote link status message received from the second wireless link device, said remote link status message indicating the status of the wired connection between the second wireless link device and a second Ethernet-compliant network device.

Abstract: The invention relates to a vessel or a floating structure operating in ice-covered waters comprising a hull or the like (1, 1?) including at least one bow-like end or a similar hull portion (2, 2?), which is exposed to the loading effect of the ice, while the ice or the vessel is moving. Said bow-like end or a similar hull portion (2, 2?), in the underwater part of the hull, is equipped with means for leading one or several strong, mainly upwards-directed flows of water towards the ice or the ice field encountered by the bow-like end or a similar hull portion (2, 2?). The invention also relates to a method of using the vessel or the floating structure.
