Apparatus and method use pre-order queuing and scheduling. Reordering of the transmission sequence of packets that could be sent out in one round is allowed according to the quantum consumption status of the flow within the round. Per-packet time complexity is maintained independent from an increase in flow number and packets of variable-length are processed.

A flow calculation unit classifies packets of data to be transmitted according to each packet header. A stream data determination unit organizes a set of packets having the same packet header as a packet group according to the classified result by the flow number calculation unit, and determines whether to transmit with a bandwidth guaranteed according to the bit rate of the packet group. A bandwidth request command generation unit requests a bandwidth control device to reserve a bandwidth for the packet group determined to be transmitted with a bandwidth guaranteed by the stream data determination unit. Therefore, a bandwidth can be automatically reserved to allow data transmission even when no transmission condition is specified by the application.

The invention is an Internet access system that puts together interactivity of the Internet and congestion-free content delivery inherent in broadcast media in order to reduce delays in content presentation. The system delivers any web object (web page, music file, video etc.) in two steps. First, a single copy of object is downloaded according to a standard Internet protocol into a server provided at a broadcast center no matter how many client computers have requested the object; then the copy is transmitted over a broadcast channel according to a data broadcast protocol so that all clients could download it simultaneously. A web object is transmitted as a flow of packets and the transmission is preceded with an announcement specifying a broadcast channel and a flow number. The packet header contains a flow number and a destination address that could be a client address or a broadcast address, thereby enabling an efficient handling of both one-to-one and one-to-many transmissions. The system provides, when necessary, a protection of transmitted content against unauthorized reception by biding packets identity and transmitting packets of the same content over different, pseudorandomly changing channels.

A method and system for concealing from an outside observer the source and destination of information transmitted over computer network. Two types of data packets are defined: content packets that are carrying application data, i.e. real information, and announcement packets that are carrying data providing delivery of content packets.
