Optimized method and optimized protocol engine for message transmission
View Patent ↗A method is provided in which at least one of the following parameters is first determined for a transmitter: parameter representative of the presence of the message oriented memory management feature in the receiver; number of message storage locations provided in the receiver; size of the message storage locations provided in the receiver. A receiver transmits to the transmitter the number of information units still permitted under time control or under event control, the receiver ascertaining this number from the number of messages received or from the number of message storage locations which are still free. The transmitter ascertains the number of messages that can still be transmitted to the receiver from the transmitted number of information units which are still permitted.
1. A method for message transmission between a transmitter and a receiver, the receiver having a message oriented memory management feature and a transport protocol between the transmitter and the receiver having a flow control feature which is oriented to the number of information units, comprising:
determining at least one of the following parameters for the transmitter: a parameter representative of the presence of the message oriented memory management feature in the receiver; a number of message storage locations provided in the receiver; and a size of the message storage locations provided in the receiver;
transmitting from the receiver to the transmitter the number of information units permitted under time control or under event control, the receiver ascertaining the number from the number of messages received or from the number of message storage locations which are free; and
ascertaining, via the transmitter, the number of messages which can be transmitted to the receiver from the transmitted number of information units which are permitted.
2. The method as claimed in claim 1 , wherein the parameter or the parameters are determined for the transmitter using administrative presets.
3. The method as claimed in claim 1 , wherein the parameters are determined for the transmitter using presets which are signaled by the receiver.
4. The method as claimed in claim 1 , wherein the information units are bytes and the transport protocol's flow control feature is byte oriented.
5. The method as claimed in claim 4 , wherein the transport protocol is a stream control protocol transmission.
6. A transceiver apparatus, comprising: a reception apparatus,
the reception apparatus having a message oriented memory management feature and a flow control feature which is oriented to the number of information units; and a transmission apparatus which supports a transport protocol, wherein,
the transmission apparatus ascertains at least one of the following parameters: a parameter representative of the presence of the message oriented memory management feature in another reception apparatus in another protocol engine which is connected to the protocol engine;
a number of message storage locations provided in another reception apparatus; and
a size of the message storage locations provided in the reception apparatus, the reception apparatus transmits the number of information units permitted under time control or under event control, the reception apparatus ascertaining the number from the number of messages received or message storage locations which are free, and
the transmission apparatus ascertains the number of messages, which can be transmitted from a received number of permitted information units.
7. The transceiver apparatus as claimed in claim 6 , wherein the transceiver apparatus stipulates administrative presets for the parameter or parameters for the transmission apparatus.
8. The transceiver apparatus as claimed in claim 6 , wherein the stipulates presets signaled by the another reception apparatus for the parameter or parameters for the transmission apparatus.
9. The transceiver apparatus as claimed in claim 6 , wherein the information units are bytes and the transceiver apparatus has a transport protocol flow control feature which is byte oriented.
10. The transceiver apparatus as claimed in claim 9 , wherein the transport protocol is a stream control transmission protocol.
