Abstract:
1. A method of managing priority during the transmission of a message in an interconnections network, the interconnections network comprising at least one transmission agent which comprises a plurality of inputs and at least one output, each input comprising a means of storage of a queue of messages of type first in first out, the method comprising: assigning a message priority during the creation of the message, the message priority being unchanged during the transmission of the message; assigning a queue priority equal to the maximum of the priorities of the messages of the queue to the queue of messages of an input; assigning a link priority to a link linking an output of a first transmission agent to an input of a second transmission agent, the link priority being equal to the maximum of the queue priorities of the queues of messages coupled to the inputs of said first transmission agent, the queues of messages coupled to the first transmission agent comprising a first message destined for that output of said first agent which is coupled to said link; calculating a resultant priority equal to a maximum of the link priority of the link and of the queue priority of the queue of messages of the input to which the link is coupled; and assigning the resultant priority to the queue of the second agent which is coupled to the link.
