Abstract: A system and method for IP POP change for a user equipment are described. The approach is taken of assigning a new IP POP to the user equipment in an ongoing packet data unit session, while maintaining packet data transmission in that session. The new IP POP is brought into commission in stages within the session, with the uplink path being moved and then the downlink path.

Abstract: A system and method for server relocation in a packet data network. A transport protocol session is established between a client 20 and server 14_1 to transfer content from the server to the client in data packets. As well as transmitting data packets to the client, the server additionally transmits declarative information as signaling packets. The declarative information includes an identifier of the content being transmitted in the ongoing session. This allows other servers 14_2 with the same content to identify the existence of the session and gives them the opportunity to volunteer to take over the session, for example if they can see that the client is now closer to them than the server currently serving the content. The two servers can then coordinate transfer of the session, whereafter the session continues with the second server transmitting content to the client.

Abstract: The disclosure relates to a method for handling congestion performed in a source node of a communication network. The communication network provides a communication path for traffic streams between the source node and a destination node, wherein the source node multiplexes two or more different types of traffic streams onto a single connection. The method comprises detecting congestion in the communication network along the communication path, determining whether there is a traffic differentiation in a network node along the communication path, and applying a connection-level congestion control for the case of determining that there is no network node performing traffic differentiation. The disclosure also relates to a source node, computer program and computer program product.

Abstract: An adaptive streaming system is described in which media content is provided by a media server as a sequence of consecutive media segments for being individually requested by a media client. A method implementation performed by a media client of the system comprises the generation of at least one request in relation to a media segment. The media segment is divided into multiple temporally scaling media segment levels and the at least one request includes a reference to at least one temporal level of the media segment. The media client then triggers transmission of the one or more request towards the media server and processes the one or more temporal levels of the media segment received from the media server in response to the one or more requests.

Abstract: It is disclosed a client node, a first network node, a second network node, and methods therefore, for enabling forward error correction, FEC, of data.

Abstract: A method and apparatus for providing data to a network terminal. A network node receives information relating to a first instance of a client running at the network terminal. Using the information, the network node concurrently runs a second instance of the client that emulates the first instance. Using the second instance, the network node generates a request for data required by the first instance. Before receiving a request for data generated by the first instance, the network node sends the request for data required by the first instance to a remote server and receives a response that includes the required data. The required data is then sent to the network terminal. The advantage of this is that the request for data required is generated before the network node receives a request from the network terminal. This allows the request to be handled more quickly.
