Abstract: A distributed load balancer in which a router receives packets from at least one client and routes packet flows to multiple load balancer (LB) nodes according to a per-flow hashed multipath routing technique. For a given packet flow, the LB nodes randomly select a server node as a target for the packet flow from among multiple server nodes and send a connection request to the server node. A load balancer module on the server node makes the decision on whether to accept or reject the connection based on one or more metrics indicating a respective server's current load. If the module accepts the connection request, a connection is established between the server and the client. Otherwise, the load balancer nodes may select another server node and try again. The connections established between clients and servers pass through the load balancer nodes, but are not terminated at the load balancer nodes.

Abstract: The invention provides a streaming client with a streaming presentation of an event, with said presentation being obtained by dynamically switching between a plurality of media streams which represent different recordings of the event. For that purpose, source data is obtained from a plurality of stream sources. The source data is constituted by content data and/or metadata of concurrent portions of the plurality of media streams. By applying a quality assessment function to the source data, a quality score is assigned to each one of the concurrent portions. This allows selection data to be generated which enables the streaming client to access a selected one of the concurrent portions of a respective media stream. For example, a segment may be selected which provides a highest quality score. By doing so, it is therefore not required anymore for a consumer to manually switch between different media streams.
