Abstract

The invention provides a sending time control method and system as well as transmission equipment. The sending time control method comprises the following steps of obtaining a moment for a first receiving point to receive a first data packet as a first moment; obtaining a moment for a second receiving point to receive the first data packet as a second moment; setting a difference between the second moment and the first moment as a delay threshold; when a difference between a moment for a second data packet to pass the second receiving point and a moment for the second data packet to pass the first receiving point is smaller than or equal to the delay threshold, after the delay of the second data packet meets the delay threshold, sending the second data packet at a first sending point; and when the difference between the moment for the second data packet to pass the second receiving point and the moment for the second data packet to pass the first receiving point is greater than the delay threshold, updating the delay threshold as a current moment difference and directly sending the second data packet at the first sending point. According to the method, the system and the transmission equipment, any transmission system can be controlled to send the data at the basic uniform speed, a problem of performance reduction of the transmission system, which is caused by jitter, is avoided to the utmost extent, increase of more hardware resources is not needed, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a data or information transmission control method, in particular to a transmission time control method, system and transmission equipment. Background technique [0002] RTT (Round Trip Time) indicates the time required to go back and forth from the sender to the receiver. TCP will sample RTT during data transmission, that is, measure the time difference between the sent data packet and its ACK, and according to the measurement The value updates the RTT value. The TCP updates the RTO (Retransmission Time Out, retransmission interval) value according to the obtained RTT value. The sending end counts each sent data packet. If the corresponding ACK of the sent data packet is not received within the RTO time, the task data packet is lost and the data will be retransmitted. Generally, the RTO value is larger than the RTT value obtained by sampling. [0003] In the actual applica...
