摘要： Modifying quality of service treatment for data flows A method of transmitting a data flow via a network is disclosed where the network supports transmission of data in accordance with a plurality of Quality of Service, QoS, models. Prior to transmission of the data flow, a client system configures a first class of service for the data flow based on a first QoS model, and a first portion of the data flow is transmitted through the network in accordance with the first class of service. In response to detecting a renegotiation condition, the network communicates with the client system to configure a second class of service for the data flow based on a second QoS model, and a subsequent portion of the data flow is transmitted through the network using the second class of service.

摘要： The present invention provides a method of operating a communications network such that the classes of service offered by a network operator will depend upon the underlying conditions in the network. A number of performance models, each of which is described by two vectors, is determined from historical network data. These performance models can be assigned to routes through the communications network, such that a request for a session can be made in accordance with the offered performance model for that route.

摘要： There are described methods and systems for distributing content in a network, in particular a multicast network. One method includes delivering content from a source to a destination in a content delivery network. A request for an item of content is received and a first multicast stream is identified or established, the first multicast stream comprising a first copy of the content. At least one second multicast stream is also identified or established, the second stream comprising a second copy of the content. The second copy of the content is time-shifted by a time, M, from corresponding portions of the first copy of the content. The content is then delivered to the destination using both the first and the second multicast streams.

摘要： A method of allocating resources in a network for the transmission of a data flow is disclosed. The method involves receiving a query specifying one or more quality-of-service (QoS) requirements for the data flow and identifying, based on the specified QoS requirements, one or more QoS models from a set of stored QoS models, each QoS model defining a class of service available in the network. A query response specifying the identified QoS models is transmitted. Subsequently, a reservation request is received specifying at least one of the identified QoS models. Resources are allocated in the network for the data flow based on the at least one QoS model specified in the reservation request.

摘要： The present invention provides a method comprising: receiving a plurality of queries, each query specifying one or more quality-of-service (QoS) requirements for the transmission of a data flow in a network; determining a query prototype, the query prototype comprising at least one QoS component value based on the one or more QoS requirements; obtaining a plurality of items of route data, wherein each item of route data is associated with a corresponding route through the network and indicates a QoS component of the corresponding route; comparing the route data with the query prototype to identify routes which match the query prototype; and in the event that a selected number of routes match the query prototype, responding to a further query by transmitting a query response comprising a new QoS model based on the matching query prototype.

摘要： A session admission process is provided which identifies the weakest link in a route between a first node and a second node and determines if the route is able to cope if the session is admitted. The suitability of a link is determined on the basis of: historical link performance; the predicted future performance of the link; and the predicted future demands on the link from other sessions supported by that link.
