US 2002/0118691 A1 · METHOD FOR PRIORITISED DATA TRANSMISSION AND DATA TRANSMISSION ARRANGEMENT

Abstract

A method for prioritised data transmission to a common transmission medium from a plurality of interface modules coupled to it, for interfacing at least one input bitstream with said common transmission medium, whereby access is arbitrated on the basis of a module priority of each interface module, is such that, for at least one interface module, the module priority is dependent on at least one connection parameter associated to packets of said at least one input bitstream. An arrangement for performing this method is described as well as several variant implementations of the method and the arrangement.

Method for prioritised data transmission to a common transmission medium (UDATA;UDATA′) of a plurality of interface modules (LIM1/LIMq;LIM1′/LIMm′) coupled to it, and interfacing at least one input bitstream (BS;LIM1BS′/LIMmBS′) with said common transmission medium (UDATA;UDATA′), each interface module of said plurality having a module priority (LIM1PR/LIMqPR;LIM1PR′/LIMmPR′) on the basis of which access to said common transmission medium is arbitrated during a grant cycle, characterised in that

for at least one interface module (LIM1;LIM1′) amongst said plurality, the module priority (LIM1PR;LIM1PR′) is dependent on at least one connection parameter associated to packets of said at least one input bitstream (BS;LIM1BS′/LIMmBS′).

Data transmission arrangement (DTA;DTA′) including a plurality of interface modules(LIM1/LIMq;LIM1′/LIMm′), for interfacing at least one input bitstream (BS;LIM1BS′/LIMmBS′) with a common transmission medium (UDATA;UDATA′), each interface module (LIM1/LIMq;LIM1′/LIMm′) including at least one storage queue (LIM1SQ1/LIMqSQq;

LIM1SQ1′/LIMmSQq′) adapted to store packets of said at least one input bitstream (BS;
LIM1BS′/LIMmBS′), prior to accessing said common transmission medium (UDATA;UDATA′), said each interface module having a respective module priority (LIM1PR/LIMqPR;
LIM1PR′/LIMmPR′) on the basis of which access to said common transmission medium (UDATA;UDATA′)is arbitrated during a grant cycle, and which is determined by an interface module priority means (LIM1PRM/LIMqPRM;
LIM1PRM′/LIMmPRM′) included in said each interface module, characterised in that,
for at least one interface module (LIM1;LIM1′) amongst said plurality, the module priority (LIM1PR;LIM1PR′) is dependent on at least one connection parameter associated to said packets of said at least one input bitstream (BS;LIM1BS′/LIMmBS′).
