Embodiment 1
[0036]The embodiment of the present invention provides a driving method for traffic shaping. The method is applicable to any situation where network congestion is caused by delayed transmission of ACK confirmation packets. The congestion in this situation mainly exists in the situation of asymmetric uplink and downlink networks at present. , For example, the bandwidth ratio of the uplink and downlink channels is 1:2, or even 1:9. At this time, it is very easy to delay sending the downlink ACK confirmation packet in the uplink channel, causing downlink congestion. Therefore, in order to clearly illustrate the present invention, the following uses traffic shaping on an uplink data transmission channel as an example for illustration, and the implementation of other situations refers to the following methods.
[0037] Such as figure 2 As shown, the method described in this embodiment includes the following steps:
[0038] Step S201, setting the timing time;
[0039] Preferably,...
Embodiment 2
[0048] An embodiment of the present invention provides a driving method for traffic shaping, to be more precise, provides a driving method for adaptive traffic shaping, the method includes all the steps of the first embodiment, and further improves the implementation process of the first embodiment expand. This embodiment is still described by taking traffic shaping on the uplink data transmission channel as an example, as shown in Figure 4 shown, including the following steps:
[0049] Step S401, setting the timing time;
[0050] Step S402, sending the data packets in the cache queue according to the preset fixed rate within the timing time; the specific implementation of this step is as follows:
[0051] Set the data packet sending threshold V T ’, the V T ’ is converted into the number of tokens, and based on the number of tokens within the timing time, the data packet is sent according to the token bucket algorithm, so that the data packet is sent at a fixed rate, whe...
Embodiment 3
[0059] This embodiment provides a driving method for traffic shaping, to be more precise, provides a driving method for adaptive traffic shaping. This embodiment is a specific implementation of the method described in Embodiment 2. On the basis of shaping theory, the process of adaptive control traffic shaping is expounded, such as Figure 5 Shown is a block diagram of adaptive traffic shaping in this embodiment.
[0060] The traffic shaping driving method described in this embodiment includes the following steps:
[0061] Step 1, the policer calls the QoS module to collect the actual sending rate of the current uplink channel and downlink channel in real time, that is, the occupied bandwidth;
[0062] Step 2, the strategist detects the average sending rate of the uplink channel and downlink channel within the period from a certain time point before to the current moment (the time range can be set randomly);
[0063] Step 3: The policer detects whether the average sending ra...
