Abstract: A method in a cache node (30) of a network comprises monitoring a secure data stream being received at the cache node from a server node, and detecting from one or more data chunks of the secure data stream that the secure data stream contains a data object that has been previously received and cached at the cache node, and sending a notification signal to the server node that the data object has been previously cached. The method may further comprise receiving one or more encryption header portions (e.g. TLS headers) from the server node, inserting a previously cached data chunk corresponding to each of the one or more encryption header portions into the data stream, and sending the data stream to a client device.

Abstract: A method and a device proxy for handling radio communication of content data from a data source to be played out on a media player of a wireless device in a wireless network. When detecting that a potential data class is available, the device proxy fetches segments of the content data from the data source over a potential data bearer dedicated for data of said potential data class. The potential data bearer is dedicated for data of the potential data class, which is less sensitive to delay than data of other data classes. The potential data bearer is also less costly to use compared to other data bearer(s). The fetched segments of content data are stored by the device proxy in an intermediate buffer, and the segments of content data are delivered from the intermediate buffer when requested by the media player.

The method comprises the steps of acquiring (S101) the data to be delivered to the mobile terminal, receiving (S102) an indication that a data download cap for the mobile terminal has been reached, and buffering (S103) the acquired data. The method further comprises the step of delivering (S104) the buffered data to the mobile terminal in bursts.

The method includes starting a switchover timer for the destination IP address in response to receiving an instruction from an Application Flow Controller (AFC) to start the switchover timer for the destination IP address and transmitting an indication to the AFC that all of the one or more TCP connections involving the destination IP address that are proxied by the transparent proxy have ended or the switchover timer for the destination IP address has expired in response to a determination that all of the one or more TCP connections involving the destination IP address that are proxied by the transparent proxy have ended or the switchover timer for the destination IP address has expired.

Abstract: A method executed by an Intermediary Node arranged between a Client and a Server for participating in the setting up of a connection between the Client and a Server is described. In response to intercepting a first message, the method transmits from the Client and destined for the Server, and requests for a connection to be set-up between the Client and the Server. The method recognizes, based on content of the received first message, that it is desirable for the Intermediary Node to perform at least one function on the requested connection, the Intermediary Node is transmitting a second message to the Client, comprising an identity of the Intermediary Node. This enables the Client to accept or reject the Intermediary Node as a node participating in the requested connection set-up.

Abstract: Method performed by a first network node (611) for determining whether a second Multi Path Transmission Control Protocol, MPTCP, connection (622) between the first network node (611) and a second network node (612) is to be initiated. The second MPTCP connection is part of a connection path (640) between a first device (631) and a second device (632). The second MPTCP connection (622) is in accordance with a second communication technology.
