Method for transmitting data packets between two communication modules and communication module for transmitting data packets, as well as communication module for receiving data packets
First Claim
1. A method for transmitting data packets between two communication modules via a transmission medium, which interconnects the two communication modules, the method comprising:
- (a) embedding, via a transmitting communication module, in the case of an ongoing transmission of a first data packet, a second data packet, which is to be sent urgently, directly into the ongoing first data packet;
(b) buffering a remainder, not transmitted yet, of the first data packet;
(c) transmitting the remainder of the first data packet after transmitting the second data packet; and
(d) buffering, via a receiving communication module, a beginning of a received first data packet;
(e) receiving the second data packet and forwarding it for further processing;
(f) receiving the remainder of the first data packet after receiving the second data packet;
(g) connecting it with the buffered beginning of the first data packet; and
(h) forwarding the complete first data packet for further processing.

Abstract
A method for transmitting data packets between two communication modules via a transmission medium interconnecting the two modules. To transmit a high-priority data packet in real time via the transmission medium, without causing erroneous transmissions of other packets, it is provided that, for an ongoing transmission of a first data packet, a transmitting communication module embeds a second data packet, which is to be sent urgently, directly into the ongoing first packet, buffers a remainder (not transmitted yet) of the first packet and transmits the remainder of the first packet after transmitting the second packet, and a receiving communication module buffers a beginning of a received first packet, receives the second packet and forwards it for further processing, and receives the remainder of the first packet after receiving the second packet, connects it with the buffered beginning of the first packet, and forwards the complete first packet for further processing.

7. A communication module for transmitting data packets to another communication module via a transmission medium, which interconnects two communication modules, comprising:
-
a transmitting communication module having a buffer for buffering a first data packet to be transmitted or a remainder of the first data packet, not yet transmitted; and a multiplexer, situated between the buffer and the transmission medium, for switching the data to be stored for transmission via the transmission medium between the first data packet buffered in the buffer or the buffered remainder of the first data packet, not yet transmitted, and a second data packet to be urgently transmitted. - View Dependent Claims (8, 9)

10. A communication module for receiving data packets from another communication module via a transmission medium, which interconnects the two communication modules, comprising:
-
a receiving communication module having a buffer for buffering a received first data packet; and a demultiplexer, situated between the transmission medium and the buffer, for switching the data received via the transmission medium between the buffer for the first data packet and an arrangement for further processing a second data packet transmitted urgently via the transmission medium and received by the communication module. - View Dependent Claims (11, 12, 13, 14, 15, 16)
