Abstract: Congestion control in a telecommunications network, in which a method of congestion control in a transport network is provided. A buffer state of a buffer is monitored by dynamically sampling the buffer such that the sampling rate is adjusted in dependence of the buffer state. Also, a condition indicative of congestion is determined in response to a change of the buffer state exceeding a predetermined limit. In response to determining the condition indicative of congestion, a congestion notification message is created. The created congestion notification message may then be transmitted to a second network node. The second network node may subsequently compensate for a detected congestion on the basis of a received congestion notification message.

Abstract: A data block is acquired, the data block is encoded, and the encoded data block is sent addressed to a network receiving node. Feedback information is received from the network receiving node regarding decoding performance of the sent encoded data block, and based on the feedback information, it is determined whether the sent data block was successfully decoded by the network receiving node. When it is determined that the sent data block was not successfully decoded, an adjusted coding parameter value of the coding parameter is determined, the data block is encoded with the adjusted coding parameter value, and the adjusted encoding parameter value data block is sent addressed to the network receiving node. When it is determined that the sent data block was successfully decoded, a subsequent data block is encoded, and the encoded subsequent data block is sent addressed to the network receiving node.

Abstract: A source network node performs routing path selection in a communications network by steps that include acquiring a dynamically changing metric value of at least one of a plurality of data routing paths extending from the source network node to a destination network node to which data is to be routed. A determination is made as to which of the data routing paths the data is to be routed on the basis of the acquired dynamically changing metric value of the at least one data routing path in order to satisfy at least one predetermined routing criterion. Routing of the data from the source network node to the destination node is then controlled to be performed over the determined data routing paths.

Abstract: A network node enables a wireless device to communicate with a local service device, such as a printer or a projector, of a Local Area Network (LAN) or Wireless Local Area Network (WLAN). The network node is connected both to a communication network and to the LAN or WLAN.

A local IP-address of the local service device is retrieved, and service data is conveyed between the wireless device and the local service device, by applying the LL-address of the local service device.
