Abstract

A method for transmitting messages in an interconnection network may include message initiating elements, message switching elements, and message destination elements. The messages may include a header and a content and are destined for processing elements capable of processing a data quantum of the content of a message independently of the other data quanta of the content of the message. The transmission of a first message is started by a switching agent, the header of the first message is stored, the transmission of the first message is interrupted when commanded and then the transmission of a second message is started whose content is the non-transmitted part of the content of the first message.

Claims

1. A method for transmitting messages in an interconnection network comprising message initiating elements, message switching elements and message destination elements, the said messages comprising a header and a content comprising data quanta, the said messages being destined for destination elements capable of processing a data quantum of the content of a message independently of the other data quanta of the content of the message wherein:

the transmission of a first message is started by a switching agent;

the header of the first message is stored;

the transmission of the first message is interrupted upon dynamic control; and

the transmission of a second message is started whose content is the non-transmitted part of the content of the first message.

2. The method according to claim 1, wherein the header of a message comprising size information indicating the size of the content of the message, the size information of the stored header of the first message, indicating the size of the non-transmitted content of the first message, is updated as the transmission of the data quanta of the first message progresses, in order to obtain a second message header.

3. The method according to claim 2, wherein after the transmission of the second message, there is assembled, on command, the transmitted part of the said first message and the second message, arriving consecutively, whilst eliminating the header of the second message.

4. The method according to claim 2, wherein with the header of a message comprising address information indicating a start address for storing the content of the message, as the transmission of data quanta of the first message progresses, the address information of the stored header of the first message, indicating the start address for storing the content of the first message is updated in order to obtain a second message header.

5. The method according to claim 1, wherein with the header of a message comprising address information indicating a start address for storing the content of the message, as the transmission of data quanta of the first message progresses, the address information of the stored header of the first message, indicating the start address for storing the content of the first message is updated in order to obtain a second message header.

6. The method according to claim 5, wherein after the transmission of the second message, there is assembled, on command, the transmitted part of the said first message and the second message, arriving consecutively, whilst eliminating the header of the second message.

7. The method according to claim 1, wherein after the transmission of the second message, there is assembled, on command, the transmitted part of the said first message and the second message, arriving consecutively, whilst eliminating the header of the second message.

8. A system for transmitting messages in an interconnection network comprising message initiating elements, message switching elements and message destination elements, the said messages comprising a header and a content comprising data quanta, the said messages being destined for destination elements capable of processing a data quantum of the content of a message independently of the other data quanta of the content of the message, the system comprising at least one switching element comprising at least one input equipped with a means of transmitting messages capable of starting the transmission of a first message, and at least one output equipped with a transmission decision means, the said transmission means comprising a storage means capable of storing the header of the first message, and the said decision means comprising a means of interrupting the transmission of the first message, and a means of starting the transmission of a second message whose content is the non-transmitted part of the content of the first message.

9. The system according to claim 8, wherein the header of a message comprising address information indicating a start address for storing the content of the message, the said message transmission means further comprising a means for updating, as the transmission of data quanta of the content of the first message progresses, the address information of the header of the first message, indicating the start address for storing the content of the non-transmitted content of the first message, in order to obtain a second message header, the said header of the first message being stored in the said storage means.

10. The system according to claim 8, wherein with the header of a message comprising size information indicating the size of the content of the message, the said message transmission means further comprising a means of updating the size information of the header of the first message, indicating the size of the non-transmitted content of the first message, as the transmission of data quanta of the content of the first message progresses, in order to obtain a second message header, the said header of the first message being stored in the said storage means.

11. The system according to claim 10, further comprising another switching element situated after the said switching element, between the initiating element and the destination element of the first message, the said other switching element comprising at least one output comprising a decision means further comprising a means of assembling the transmitted part of the said first message and the second message, arriving consecutively, whilst eliminating the header of the second message.

12. The system according to claim 10, wherein the header of a message comprising address information indicating a start address for storing the content of the message, the said message transmission means further comprising a means for updating, as the transmission of data quanta of the content of the first message progresses, the address information of the header of the first message, indicating the start address for storing the content of the non-transmitted content of the first message, in order to obtain a second message header, the said header of the first message being stored in the said storage means.

13. The system according to claim 12, further comprising another switching element situated after the said switching element, between the initiating element and the destination element of the first message, the said other switching element comprising at least one output comprising a decision means further comprising a means of assembling the transmitted part of the said first message and the second message, arriving consecutively, whilst eliminating the header of the second message.

14. The system according to claim 8, further comprising another switching element situated after the said switching element, between the initiating element and the destination element of the first message, the said other switching element comprising at least one output comprising a decision means further comprising a means of assembling the transmitted part of the said first message and the second message, arriving consecutively, whilst eliminating the header of the second message.
