A method for service management for terminals with broadband connections, wherein the terminal is connected through a home gateway to a service connected in an operator network, the home gateway being attached to an access node of the operator network, includes the steps of monitoring whether the terminal is temporarily not using the service, delegating the service and transferring its current status and/or data to the access node, and tearing down the connection between the home gateway and the access node while operating the service in the delegated service host.

A method of policing network traffic based on congestion on a flow-based programmable switch, such as an OpenFlow switch is provided. The method polices congestion-causing flows in a network by detecting congestion at a flow-based programmable switch on the network. Once congestion has been detected, the method identifies one or more flows that are causing the congestion at the flow-based programmable switch, and penalizes the flows that were identified as causing congestion. A flow-based programmable switch including a data plane having input ports, output ports, and forwarding rules that map packets received on an input port to an output port based on a packet matching a rule in the forwarding rules is also described.

A method for supporting the selection of communication peers in an overlay network, wherein a multitude of communication peers participate in the overlay network by providing certain pieces of information, and wherein at least one peer-to-peer server&#x2014;tracker&#x2014;is provided that maintains a database of the participating communication peers and the information possessed by them, wherein the tracker, upon receiving a query regarding a specific piece of information from a communication peer&#x2014;requesting client&#x2014;, answers the query by providing the requesting client a list that includes a subset of all communication peers possessing the requested piece of information, includes providing a network entity located such that it receives messages directed from the requesting client to the tracker, wherein the network entity stamps topological location information of the requesting client into any of the messages directed from the requesting client to the tracker. Furthermore, a corresponding system is disclosed.

For allowing a high degree of resource consumption within a network a method for operating a network is claimed, wherein at least one end user device is connected to an access network, wherein the method is characterized in that the at least one end user device or an application on the end user device queries at least one network element of the access network and/or at least one network element attached to the access network about low layer parameters information for optimizing connection and/or protocol parameters after having received the queried low layer parameters information. Further, a network is claimed, preferably for carrying out the above mentioned method.
