Embodiment Construction

[0034] The present invention is a method for controlling the flow of IP data packets. Its core idea is: to pre-set the average time interval between two adjacent data packets sent to the user, and sequentially store the data sent to the user If the current queue meets the average time interval condition, the first data packet in the queue will be sent to the user, and then the next queue will be processed; if the current queue does not meet the average time interval condition, it will not be sent to the user packet and proceed directly to the next queue.

[0035] figure 1 Shown is the flow chart of Embodiment 1 of the data flow control method of the present invention, which executes:

[0036] Step 101, judge whether the difference between the current time and the sending time of the last data packet in the current queue is greater than the preset average time interval, if yes, execute step 102; otherwise, execute step 103, the queue is used to store the same destination addre...

Abstract

A method for data flow control comprises: determining whether the difference between the current time and the time at which the last data packet of the current queue was transmitted is larger than the predetermined average time interval, if so, transmitting the first data packet in the queue and processing the next queue, otherwise, processing the next queue directly, said queues stores the data packets having the same destination address. The device for data flow control comprises a queue-storing module, a scheduling-and-transmitting module and a comparing module.

Description

technical field [0001] The invention relates to a network data transmission technology, in particular to a data flow control device and a flow control method. Background technique [0002] With the development of modern electronic technology, the performance of various processors has been rapidly improved. In the core network field of telecommunication networks, with the development of VOIP (voice over IP, IP telephony) technology, the traditional switching technology with TDM (Time Division Multiplex) switching as the core is turning to packet switching with IP technology as the core Technology advances. Judging from the data transmitted by the switching network, the original connection-based data flow has gradually evolved into an IP-based connectionless data flow. Since the all-IP network system has the characteristics of high standardization, low R&D costs, and short development cycle, it will become the development trend of the future network. [0003] In the prior a...
