Method and system for transporting data packets of a data stream

A system to transport data packets of a data stream between a packet-oriented network and a channel-oriented data stream processing module, comprising:

• an interface module to exchange the data packets with the network;
• a data channel allocation module coupled to the interface module and to the data stream processing module;
• a data stream controller, coupled to the data channel allocation module, to control the data packet transport, and transmit a data channel allocation information item;
• a channel allocation memory provided in at least one of the interface module and the data stream processing module to store the data channel allocation information item;
• and
• an additional interface for direct transmission of the data packets by the data channel allocation information item stored in the channel allocation memory, the additional interface being provided between the interface module and the data stream processing module.

A device comprising:

• a data stream processing module connected to a plurality of data stream channels;
• an plurality of input queues, each of the plurality of data stream channels having a corresponding input queue;
• an interface module to receive data packets from a packet-oriented network;
• a data stream controller to transmit the queue identifiers to the interface module and transmit address information items to the data stream processing module;
• a first memory provided in the interface module to store a connection table identifying port numbers associated with the packets which can be received;
• a first processor to associate port numbers with queues identified by the queue identifiers received from the data stream controller;
• a second memory provided in the data stream processing module to store a second connection table identifying the plurality of data stream channels and the port numbers associated therewith;
• and
• a second processor to associate port numbers with data channels identified by the address information items received from the data stream controller.
