Method for the optimized transmission of data bursts between a sending and a receiving network node
First Claim
1. A method for transmitting data bursts between a sending network node and a receiving network node over a switching device of a data network, comprising:
- transmitting a first data burst;
transmitting a reservation request;
transmitting an acknowledgement signal;
wherein the sending network node receives information regarding a blocking time while transmitting the first data burst;
wherein the reservation request and the acknowledgement signal includes information regarding the blocking time by means of a signalling overhead;
waiting for expiration of the blocking time; and
transmitting a second data burst from the sending network node to the receiving network node immediately after expiration of the blocking time.

Abstract
The invention relates to an optical data burst transmission method. An emitted network node obtains, together with a confirmation signal, information regarding the length of time of after which blocking no longer occurs and/or information indicating when the connection path is free. The emitted network node can be immediately emitted after an actual emitted data burst, another data burst and after other bursts. As a result, waiting time between the bursts is prevented and the available transmission capacity is used in an optimal manner. The probability of blocking is also reduced as is the necessary signaling information.

12. A method for transmitting data bursts between a sending network node and a receiving network node over a switching device of a data network, comprising:
-
transmitting a first data burst; transmitting a reservation request; transmitting an acknowledgement signal; transmitting to the sending network node information including the point in time of the beginning of an available connection or a blocking time of the existing connection until the beginning of an available connection, and the point in time of the termination of the available connection or the duration of the available connection or a length of time until the end of the available connection; wherein the sending network node receives said information regarding the blocking time while transmitting the first data burst; wherein the reservation request and the acknowledgement signal includes information regarding the blocking time by means of a signalling overhead; waiting for expiration of the blocking time; and transmitting a second data burst from the sending network node to the receiving network node immediately after expiration of the blocking time. - View Dependent Claims (13)

14. A method for transmitting data bursts between a sending network node and a receiving network node over a switching device of a data network, comprising:
-
transmitting a first data burst; transmitting a reservation request; transmitting an acknowledgement signal; transmitting to the sending network node information containing the point in time of the beginning of an available connection or a remaining blocking time of an existing connection, and the duration of the available connection; wherein the reservation request and the acknowledgement signal includes information regarding the blocking time by means of a signalling overhead; wherein the sending network node receives said information regarding the blocking time while transmitting the first data burst; waiting for expiration of the blocking time; and then transmitting a second data burst from the sending network node to the receiving network node immediately after expiration of the blocking time.
