Data flow control in a network
In order to implement a method for data flow control in a network with reduced overhead, a first subscriber transmits data symbols in data frames to a second subscriber. The second subscriber forwards and/or processes the data frame. If there is a delay in forwarding and/or processing the data frame, the second subscriber instructs the first subscriber to pause the transmission of the data frames with a granularity of one data symbol. After the pause, the first subscriber continues to transmit the data frames with a granularity of one data symbol.
1. A network comprising:
a first switch designated as a first subscriber; and
a second switch designated as a second subscriber connected to the first subscriber via a data connection,
wherein the first subscriber is designed to transmit data frames, which contain data symbols, to the second subscriber via the data connection,
wherein the second subscriber is designed to instruct the first subscriber to pause the transmitting of the data frames with a granularity of one data symbol, whereby the transmitting of a data frame is paused between successive first and second data symbols within the data frame, and wherein after the pause, the first subscriber is designed to continue the transmission of the data frames with a granularity of one data symbol, whereby the transmitting of the data frame continues from between the successive first and second data symbols within the data frame.
2. The network according to claim 1 , wherein the second subscriber comprises a symbol buffer for buffering received data frames.
3. The network according to claim 1 is a real-time network.
