Japanese Patent JP2005512462
Kind Code:
A
Abstract:
The present invention relates to a transmission system for transmitting source application data units to a destination application via a network comprising a plurality of network protocol stacks. Such a transmission system provides a solution for transmitting additional information from a layer of a first network protocol stack to a layer of a second network protocol stack, without disturbing the way in which ordinary streams are processed. To this end, it further comprises: generating means for generating additional information at a layer of a first network protocol stack to be sent to a layer of a second network protocol stack via at least said first and second network protocol stacks, adapting means for converting said additional information into at least one additional data unit compliant with network protocol rules, marking means for marking said additional data units, retrieving means for retrieving said additional information within said additional data units when said additional data units arrive at said layer of said second network protocol stack. More generally, the invention deals with all the possible exchanges of additional information between layers of network protocol stacks within a transmission system. Said transmission system may also include some routers.
