摘要： A method for monitoring a status in a form of presence and/or absence of a subscribed network entity in a network by a presence service, wherein the network is a software defined network having one or more forwarding elements being configurable for recognizing and applying one or more actions on packets being forwarded by the forwarding elements and one or more network entities, includes monitoring the status of the subscribed network entity. The monitoring the status of the subscribed network entity includes providing the presence service with a status update of the selected network entity only when at least one of the one or more forwarding elements, to which the selected network entity is directly connected, has detected a change in the presence status of the subscribed network entity; and dropping packets of the subscribed network entity destined for the presence service.

摘要： A method for controlling the admission of a flow to a network, particularly a WiMAX (Worldwide Interoperability for Microwave Access) network, wherein an estimation of maximum capacity required within a link of the network and/or within the network will be performed for examining, whether the flow requesting to enter the network with at least one QoS (Quality of Service) reservation of resources can be admitted, by finding first sets of intersections between all pairs of QoS reservations, i.e. the QoS reservations already accepted within the link and/or within the network and the at least one QoS reservation requested by the flow. The method is characterized by structuring the found sets of intersections by building a matrix of intersections of QoS reservations and—based on the matrix—deriving the rest of the sets of intersections between the intersections found, based on information obtained regarding the QoS reservations involved in each intersection.

摘要： For allowing an intelligent and/or resource efficient delivery of video content and/or determining of video content popularity and/or user behavior a method for determining user behavior during delivery of video content is claimed, wherein a user is requesting a delivery of a video content from a provider via a network. The method is characterized in that the provider exploits information transmitted between the user and the provider due to the execution of a trick play function by the user for scheduling the delivery and/or determining video content popularity and/or user behavior. Further, an according network is claimed, preferably for carrying out the above mentioned method.
