A system and method are disclosed for managing the wireless delivery of streaming media content to a user equipment (UE) device. A UE device establishes a network connection with a local wireless network, which in turn is associated with a wireless network region with a corresponding data infrastructure server. The UE device then requests predetermined streaming media content from the data infrastructure server. A determination is made whether the requested streaming media content is stored in transcoded form on the data infrastructure server. If so, then a control information network is implemented to transmit and receive streaming media content control data between the UE device and the data infrastructure server. In turn, the streaming media content control data is used by the data infrastructure server to control the transmission of the transcoded streaming media content over a data network for delivery to the UE device.

Mobile media content delivery

A communication device and method for throttling transmitted data is provided. Token parameters of an aggregate token bucket, associated with a communication application, are distributed, at a processing unit, to respective application token buckets associated with at least two further applications. The communication application is enabled to receive respective data from the at least two further applications for transmission to a network via a communication interfaces. The respective data received from the at least two further applications is throttled via the respective application token buckets.

Communication device for throttling transmitted data

A method is given for sharing reserved bandwidth between a plurality of connections issuing from a port of a node. A connection bandwidth is determined for each connection of the plurality of connections. An aggregate bandwidth is determined for all connections of the plurality of connections issuing from the port, the aggregate bandwidth being less than a sum of the connection bandwidth for all connections. The aggregate bandwidth is compared with a maximum access rate for the port, and in the event that the aggregate bandwidth does not exceed the maximum access rate, reserving the aggregate bandwidth for the port.

Method and system for sharing reserved bandwidth between several dependent connections in high speed packet switching networks

A method for establishing a network connection through a link issuing from a physical port is disclosed. The link has an aggregation of connections. The network connection has a required capacity. The method first computes, from mean bit rates of the aggregation of connections, a mean aggregate bit rate over the aggregation of connections. The method secondly computes, from burst durations from the aggregation of connections, a mean aggregate burst duration over the aggregation of connections. The method thirdly computes an equivalent capacity required on the link by the aggregation of connections, the equivalent capacity being a function of the mean aggregate bit rate and the mean aggregate burst duration. The method fourthly computes an aggregate equivalent capacity, the aggregate equivalent capacity being a function of the equivalent capacity and the required capacity of the connection. The method fifthly computes a bandwidth that would be reserved on the link after establishing the connection, the bandwidth being a minimum of a Gaussian approximation and the aggregate equivalent capacity. Then the network connection is established if the bandwidth is less than or equal to a total capacity for the link.

Method and system for non disruptively assigning link bandwidth to a user in a high speed digital network

A method based on predefined connection priorities for assigning link bandwidth to a requesting user in a high speed digital network interconnecting network users through a path including network nodes connected through high speed links. According to this method, a predefined reservable link bandwidth is split into so-called nominal bandwidth portions and common bandwidth portions, both assignable to the same connections on a priority basis. Each of the common bandwidth priorities is individually related to a nominal bandwidth priority through a predefined relationship, making the common bandwidth priorities always lower than any nominal priority. In this way the requested link connection bandwidth, whatever be its nominal priority, is made preemptable primarily on all common bandwidth, thus avoiding the disruption of any network connection which is already established.
