Description

传输速率的确定方法、装置、设备和存储介质
本申请要求在2019年07月25日提交中国专利局、申请号为201910677502.0的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及数据传输领域，例如涉及一种传输速率的确定方法、装置、设备和存储介质。
背景技术
随着互联网技术的飞速发展，在不同设备上的数据传输也越来越普遍，此时为了提高数据传输过程中网络带宽的利用率，提出了一种全新的拥塞控制算法(Bottleneck Bandwidth and Round-trip Propagation Time，BBR)，该BBR算法能够通过不同的工作状态来探测网络带宽的最大值以及往返时延的最小值，进而根据网络带宽的最大值和往返时延的最小值确定数据传输的速率，提高网络带宽的利用率，并有效降低网络数据传输的往返时延。
相关技术中的BBR算法在控制网络工作于带宽探测状态时，会内置一个传输周期，该传输周期默认累计8个往返时延，分为1个增益子周期、1个减损子周期和6个平稳发送子周期三部分，默认设置该传输周期内增益子周期的发送速率增益系数为1.25，减损子周期的发送速率增益系数为0.75和平稳发送子周期的发送速率增益系数为1，此时BBR算法可以在增益子周期控制多发送25％的数据，而如果当前网络丢包率大于25％，那么增益子周期内多发送的数据则会完全被丢包抵消，而在减损子周期又减少了25％的数据发送，使得该传输周期的整体数据量减少，导致当前探测的网络带宽低于最大带宽，使得按照当前探测的网络带宽所确定的在下一传输周期内的数据传输量降低，从而降低了多个传输周期的数据传输速率，最终导致网络中数据的传输速率出现断崖式的下降。

具体实施方式
下面结合附图和实施例对本申请进行说明。此处所描述的实施例仅仅用于解释本申请，而非对本申请的限定。为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
实施例一
图1A为本申请实施例一提供的一种传输速率的确定方法的流程图，本实施例可应用于任一种向其他设备发送对应数据的终端设备中。本实施例提供的一种传输速率的确定方法可以由本申请实施例提供的传输速率的确定装置来执行，该装置可以通过软件和/或硬件的方式来实现，并集成在执行本方法的设备中，该设备可以是具备数据传输功能的任一种终端设备。
参考图1A，该方法可以包括如下步骤：
S110，获取与上一传输周期内探测到的带宽极值匹配的传输速率，并将所述传输速率作为当前传输周期的传输速率基值。
本实施例主要针对相关技术中的BBR算法中采用固定模式下的增益系数调整不同阶段的传输速率，而存在的网络中数据传输率大幅度下降的问题，通过对该BBR算法进行改进，使得该BBR算法针对不同阶段的网络传输状态，能够采用不同模式下的增益系数对传输速率进行调整，从而保证数据传输的性能。
该BBR算法在网络中稳定工作后会交替处于预先设置的带宽检测状态(PROBE_BW)和时延检测状态(PROBE_RTT)；PROBE_BW状态用于探测数据传输过程中可用的最大网络带宽，PROBE_RTT状态用于探测数据传输过程中的最小时延，此时当在PROBE_BW状态下的预设时长内未检测到数据传输的最小时延时，则跳转至PROBE_RTT状态工作，此时仅控制发送4pkts/RTT的数据量(接近于停止发送)，从而排空网络中传输的数据包，进而探测真实的最小时延。在PROBE_BW状态下传输数据时，会内置对应的传输周期，此时在每一传输周期内均会根据实际的数据传输情况实时探测对应的网络带宽，进而确定满足该网络带宽的传输速率，此时通过分析不同传输周期中的数据传输情况能够及时准确地判断在不同时刻下数据传输对应的网络状态。带宽极值为不同传输周期中根据实际的数据传输所探测的网络带宽的最大可用值；传输速率基值为在避免数据传输拥塞的基础上，能够最大程度满足该带宽极值的传输速率。
可选的，工作于PROBE_BW状态时，在每一传输周期下，均会传输对应指定数量的数据来探测当前网络中的最大可用带宽值(本实施例中的带宽极值)，本实施例在上一传输周期传输指定数量的数据后，可以根据上一传输周期内实 际的数据传输情况探测出上一传输周期对应的带宽极值，保证网络带宽的准确性，此时将上一传输周期内探测到的带宽极值作为当前传输周期的参考带宽，进而将最大程度满足该带宽极值的传输速率作为当前传输周期的传输速率基值，以便后续根据数据传输过程中网络状态的变化情况对该传输速率基值进行调整，以满足当前传输周期对应的网络带宽，提高数据的传输速率。
S120，确定由历史传输周期内网络参数的变化预估的当前传输周期内带宽的变化对应的增益系数。
网络参数为数据传输过程中对于网络带宽和满足该网络带宽的传输速率之间的匹配关系存在一定影响的参数，如网络丢包率等；示例性的，如果网络存在一定的网络丢包率时，可以在同一网络带宽下通过提高数据的传输速率来保证网络中传输数据量的稳定性。增益系数为根据网络状态的变化所确定的用于调整传输速率基值以满足当前传输周期的网络状态的调整比例。
由于当前传输周期的传输速率基值是由上一传输周期探测到的带宽极值作为参考而确定的，此时该传输速率基值在最大程度上能够满足上一传输周期的网络带宽，但是当前传输周期的网络状态会在上一传输周期的网络状态上发生变化，此时需要根据当前传输周期之前的多个历史传输周期内的网络状态的变化程度判断当前传输周期的实际传输速率在当前传输周期的传输速率基值上的浮动程度，也就是通过分析网络参数在连续多个历史传输周期内的变化，判断当前传输周期与上一传输周期的传输速率的变化情况，从而确定当前传输周期的增益系数，以便后续采用该增益系数对传输速率基值进行调整，以满足当前传输周期的实际网络状态。例如，历史传输周期内网络参数不断增大，此时可以根据上一传输周期内探测到的带宽极值和历史传输周期内网络参数的增大幅度，预估出当前传输周期的实际网络带宽，从而及时准确地判断当前的网络状态，进而确定当前传输周期的增益系数。
示例性的，BBR算法在工作于PROBE_BW状态时，为了准确探测每一传输周期的带宽极值，通常会将传输周期设置成三个周期区间，如图1B所示，此时每一传输周期中均包括增益子周期、减损子周期和平稳发送子周期三部分。同时，该BBR算法中默认设置8个数据往返时延组成一个传输周期，此时增益子周期和减损子周期均对应1个数据往返时延，平稳发送子周期对应6个数据往返时延；此时在本实施例中，根据历史传输周期内网络参数的变化，确定当前传输周期的增益系数，可以包括：确定由历史传输周期内网络参数的变化预估的当前传输周期内带宽极值的变化对应的当前传输周期内的增益子周期下的第一增益系数；根据第一增益系数，确定在当前传输周期内的减损子周期下的第二增益系数，并设置在当前传输周期内的平稳发送子周期下的第三增益系数， 得到当前传输周期内在不同工作时刻下的增益系数。
可选的，为了提高传输周期中的网络带宽的探测效率，本实施例会将整个传输周期的带宽探测工作集中在增益子周期中完成，提高带宽的探测效率，此时每一传输周期中所包含的任一子周期均对应有不同的增益系数。在传输周期包含的增益子周期中专门采用较高于传输速率基值的实际传输速率来传输数据，也就是提高增益子周期内的数据传输量，以根据较高数量的数据传输情况探测网络中可用的带宽极值；此时，由于增益子周期的传输速率需要高于传输速率基值，所以增益子周期对应的第一增益系数一定大于1，通过对历史传输周期内网络参数的变化情况进行分析，得出用于探测带宽极值的数据传输速率高于传输速率基值的比例，并将该比例作为当前传输周期内的增益子周期下的第一增益系数。示例性的，首先可以判断上一传输周期内的增益子周期下的第一增益系数，进而根据历史传输周期内网络参数的变化情况，分析增益系数的变化程度，进而根据上一传输周期内的增益子周期下的第一增益系数和增益系数的变化程度确定当前传输周期内的增益子周期下的第一增益系数；而平稳发送子周期仅需要按照当前传输周期的传输速率基值正常的传输数据即可，因此设置在当前传输周期内的平稳发送子周期下的第三增益系数为1；此时为了避免造成数据传输拥塞，需要保证每一传输周期内数据传输速率的稳定，因此在增益子周期提高传输速率后，需要在减损子周期相应的减少传输速率，此时可以根据增益子周期下的第一增益系数，确定在当前传输周期内的减损子周期下的第二增益系数，该减损子周期的第二增益系数一定小于1；例如，若增益子周期的第一增益系数为1.5，则减损子周期的第二增益系数为0.5，平稳发送子周期下的第三增益系数为1，本实施例中平稳发送子周期下的第三增益系数为固定值，不根据历史传输周期内网络参数的变化而变化。
S130，根据增益系数调整传输速率基值，得到当前传输周期的传输速率。
可选的，在确定当前传输周期的传输速率基值和增益系数后，可以通过该增益系数来调整该传输速率基值，也就是将传输速率基值乘以增益系数，得到当前传输周期的实际传输速率，后续在当前传输周期中采用该实际传输速率传输相应的数据，此时该实际传输速率能够最大程度满足当前传输周期的网络带宽，从而在数据传输过程中充分利用当前的网络带宽，提高数据的传输速率。
示例性的，在确定当前传输周期内的增益子周期下的第一增益系数，减损子周期下的第二增益系数和平稳发送子周期下的第三增益系数时，如图1B所示，本实施例中根据增益系数调整传输速率基值，得到当前传输周期的实际传输速率，可以包括：分别根据第一增益系数、第二增益系数和第三增益系数调整传输速率基值，得到在当前传输周期内的增益子周期、减损子周期和平稳发送子 周期下的实际传输速率。
分别将第一增益系数、第二增益系数和第三增益系数乘以该传输速率基值，得到在当前传输周期内的增益子周期、减损子周期和平稳发送子周期下对应的实际传输速率，后续在当前传输周期内传输数据时，在增益子周期内通过增益子周期下对应的实际传输速率传输数据，在减损子周期内通过减损子周期下对应的实际传输速率传输数据，在平稳发送子周期内通过平稳发送子周期下对应的实际传输速率传输数据；例如增益子周期的第一增益系数为1.5，减损子周期的第二增益系数为0.5，平稳发送子周期下的第三增益系数为1，传输速率基值为2kb/s时，此时增益子周期下对应的实际传输速率为3kb/s，减损子周期下对应的实际传输速率位1kb/s，平稳发送子周期下对应的实际传输速率为2kb/s。
本实施例提供的技术方案，在上一传输周期的数据传输过程中探测对应的带宽极值，判断当前的网络状态，进而确定当前传输周期的传输速率基值，并根据历史传输周期内网络参数的变化情况，确定当前传输周期的增益系数，此时通过该增益系数调整传输速率基值，得到当前传输周期的传输速率，使得该当前传输周期的传输速率最大程度的符合当前传输周期的网络状态，本方案针对不同的网络状态实时调整对应的传输速率，无需采用默认的固定模式下的传输速率来传输数据，通过当前传输周期的传输速率传输数据时，能够充分利用当前传输周期的网络带宽，提高数据的传输速率。
实施例二
图2A为本申请实施例二提供的一种传输速率的确定方法的流程图，图2B为本申请实施例二提供的传输速率的确定过程的原理示意图。本实施例在上述实施例的基础上进行说明。如果网络参数包括数据传输过程中的网络丢包率和接收速率，本实施例对于通过历史传输周期内网络参数的变化，确定当前传输周期的增益系数的过程进行说明。
可选的，如图2A所示，本实施例中可以包括如下步骤：
S210，获取与上一传输周期内探测到的带宽极值匹配的传输速率，并将所述传输速率作为当前传输周期的传输速率基值。
S220，获取历史传输周期内的网络参数。
可选的，在根据历史传输周期内网络参数的变化，确定当前传输周期的增益系数之前，首先需要获取当前传输周期之前的预设数量的历史传输周期内对应的数据传输过程中的网络参数的值，以便后续准确判断历史传输周期内网络参数的变化情况，从而准确判断当前传输周期的网络状态。本实施例中网络参 数包括数据传输过程中的网络丢包率和接收速率，此时如图2B所示，通过对历史传输周期内的数据传输情况进行分析，得到多个历史传输周期内在数据传输过程中的网络丢包率和接收速率的值。
示例性的，网络丢包率的计算公式为：
Figure PCTCN2020098083-appb-000001
loss_rate表示历史传输周期的网络丢包率，loss_num表示历史传输周期内统计的丢包数量，ack_num表示历史传输周期内统计的传输后确认包数。
接收速率的计算公式为：
Figure PCTCN2020098083-appb-000002
ack_rate表示历史传输周期的接收速率，acked_bytes表示历史传输周期内累计接收到确认的字节数，cycle_end_time表示历史传输周期的结束时间，cycle_start_time表示历史传输周期的开始时间。
本实施例中网络丢包率和接收速率等网络参数在按照传输周期统计时，要求该传输周期满足有效性条件，该有效性条件包括但不限于统计的历史传输周期的数量大于设定门限、统计的历史传输周期内的多项参数的样本数量(如丢包数量、确认包数和接收到确认的字节数等)大于设定门限以及统计的历史传输周期内排除异常阶段样本(如排除工作在PROBE_RTT状态下的样本点)等。
S230，在历史传输周期内网络丢包率保持动态稳定，且接收速率不断降低的情况下，将在上一传输周期内的增益子周期下的第一增益系数增加预设步长，得到在当前传输周期内的增益子周期下的第一增益系数。
可选的，判断历史传输周期内网络参数的变化情况，也就是判断历史传输周期内的网络丢包率和接收速率的变化情况，此时如果在历史传输周期内网络丢包率保持动态稳定，且接收速率不断降低，说明数据的传输速率较慢，为了保证当前传输周期内传输数据的稳定，首先获取上一传输周期内的增益子周期下的第一增益系数，并将上一传输周期内的增益子周期下的第一增益系数增加预设步长，从而得到当前传输周期内的增益子周期下的第一增益系数。
在一实施例中，历史传输周期内网络丢包率保持动态稳定可以为多个历史传输周期内的网络丢包率均在预设的网络丢包率范围内，或者多个历史传输周期中任意两个历史传输周期内的网络丢包率之间的差值均小于预设的网络丢包率差值，或者多个历史传输周期中相邻两个历史传输周期内的网络丢包率之间的差值小于预设的网络丢包率差值。
S240，在历史传输周期内网络丢包率不断上升，且接收速率保持动态稳定的情况下，将在上一传输周期内的增益子周期下的第一增益系数减少预设步长，得到在当前传输周期内的增益子周期下的第一增益系数。
可选的，如果在历史传输周期内网络丢包率不断上升，且接收速率保持动态稳定，说明数据的传输速率较快，在网络丢包率不断上升时还能使接收速率保持动态稳定，此时为了保证当前传输周期内传输数据的稳定，首先获取上一传输周期内的增益子周期下的第一增益系数，并将上一传输周期内的增益子周期下的第一增益系数减少预设步长，从而得到当前传输周期内的增益子周期下的第一增益系数。
在一实施例中，历史传输周期内接收速率保持动态稳定可以为多个历史传输周期内的接收速率均在预设的接收速率范围内，或者多个历史传输周期中任意两个历史传输周期内的接收速率之间的差值均小于预设的接收速率差值，或者多个历史传输周期中相邻两个历史传输周期内的接收速率之间的差值小于预设的接收速率差值。
本实施例中的S230和S240根据历史传输周期内网络参数的变化情况仅执行其中一个步骤，而且预设步长根据历史传输周期中第一增益系数的增加或者减少的次数动态变化，如第一次增加预设步长时，预设步长为较小值，而在后续的传输周期中持续增加预设步长时，该预设步长调整为一个较大值，以便减少第一增益系数的处理次数，提高第一增益系数的准确度和确定效率。
S250，根据第一增益系数，确定在当前传输周期内的减损子周期下的第二增益系数，并设置在当前传输周期内的平稳发送子周期下的第三增益系数。
S260，分别根据第一增益系数、第二增益系数和第三增益系数调整传输速率基值，得到在当前传输周期内的增益子周期、减损子周期和平稳发送子周期下的传输速率。
本实施例提供的技术方案，在上一传输周期的数据传输过程中探测对应的带宽极值，判断当前的网络状态，进而确定当前传输周期的传输速率基值，并根据历史传输周期内网络丢包率和接收速率的相对变化情况，确定当前传输周期的增益系数，提高增益系数的准确性，后续通过该增益系数调整传输速率基值，得到当前传输周期的传输速率，使得该当前传输周期的传输速率最大程度的符合当前传输周期的网络状态，本方案针对不同的网络状态实时调整对应的传输速率，无需采用默认的固定模式下的传输速率来传输数据，通过当前传输周期的传输速率传输数据时，能够充分利用当前传输周期的网络带宽，提高数据的传输速率。
实施例三
图3A为本申请实施例三提供的一种传输速率的确定方法的流程图，图3B为本申请实施例三提供的传输速率的确定过程的原理示意图。本实施例在上述实施例的基础上进行说明。本实施例主要对当前传输周期内的增益子周期中的第一增益系数的调整范围进行说明。
可选的，如图3A所示，本实施例中可以包括如下步骤：
S310，获取与上一传输周期内探测到的带宽极值匹配的传输速率，并将所述传输速率作为当前传输周期的传输速率基值。
S320，对历史传输周期内的网络丢包率进行滤波处理，得到网络丢包参数。
本实施例在调整当前传输周期内的增益子周期下的第一增益系数时，为了避免第一增益系数超出范围使得实际传输速率过大或者过小，导致数据传输拥塞或者数据传输过慢的情况，需要为增益子周期设置一个对应的预设系数调整范围，此时会根据网络丢包参数相应确定预设系数调整范围的系数调整上限，因此本实施例在获取历史传输周期内的网络丢包率后，首先对多个历史传输周期内的网络丢包率进行滤波处理，例如采用相关技术中的滑动平均滤波或其他滤波方式对网络丢包率进行滤波处理，将网络丢包率的滤波结果作为本实施例中的网络丢包参数，后续根据网络丢包参数所处的区间，确定预设系数调整范围的系数调整上限。
S330，设置增益子周期对应的预设系数调整范围的系数调整下限。
可选的，本实施例是对相关技术中的BBR算法中默认的固定模式进行改进，此时可以将相关技术中的BBR算法中固定模式下的增益子周期对应的第一增益系数作为当前传输周期内的增益子周期对应的预设系数调整范围的系数调整下限，后续调整在当前传输周期内的增益子周期下的第一增益系数时，不能低于该系数调整下限。
S340，根据网络丢包参数确定增益子周期对应的预设系数调整范围的系数调整上限。
可选的，通过网络丢包参数分析当前的网络状态，对于不同区间的网络丢包参数采用不同的方式计算当前传输周期内的增益子周期对应的预设系数调整范围的系数调整上限。
示例性的，本实施例预先为网络丢包参数分为三个区间，不同区间下的网络丢包参数采用不同的方式确定增益子周期对应的预设系数调整范围的系数调 整上限；此时，如图3B所示，本实施例中根据网络丢包参数确定增益子周期对应的预设系数调整范围的系数调整上限，可以包括：在网络丢包参数小于预设丢包下限的情况下，确定系数调整上限为第一预设系数上限；在网络丢包参数大于预设丢包上限的情况下，确定系数调整上限为第二预设系数上限；在网络丢包参数大于等于预设丢包下限，且小于等于预设丢包上限的情况下，根据网络丢包参数计算系数调整上限。
本实施例对于网络丢包参数所分的三个区间分别设置不同的系数调整上限；在网络丢包参数小于预设丢包下限的区间设置预设系数调整范围的系数调整上限为第一预设系数上限，在网络丢包参数大于预设丢包上限的区间设置预设系数调整范围的系数调整上限为第二预设系数上限，在网络丢包参数所处的由预设丢包下限和预设丢包上限组成的中间区间，设置对应的系数调整上限的计算公式为：
Figure PCTCN2020098083-appb-000003
pacing_gain为由预设丢包下限和预设丢包上限组成的中间区间的系数调整上限，smmothed_loss_rate为对历史传输周期的网络丢包率进行滤波得到的网络丢包参数。如果网络丢包参数大于等于预设丢包下限，且小于等于预设丢包上限，则采用上述计算公式根据该网络丢包参数计算预设系数调整范围的系数调整上限。
S350，根据历史传输周期内网络参数的变化，在增益子周期对应的预设系数调整范围内调整在当前传输周期内的增益子周期下的第一增益系数。
可选的，本实施例在根据历史传输周期内网络参数的变化，调整在当前传输周期内的增益子周期下的第一增益系数时，仅在该增益子周期对应的预设系数调整范围内进行调整，此时要求调整后的第一增益系数不能超出预设系数调整范围的系数调整上限和系数调整下限。示例性的，如果在历史传输周期内网络丢包率保持动态稳定，且接收速率不断降低，而将在上一传输周期内的增益子周期下的第一增益系数增加预设步长时，需要保证增加后的第一增益系数不能超出系数调整上限，在上一传输周期内的增益子周期下的第一增益系数增加预设步长后超出系数调整上限的情况下，直接将该系数调整上限作为当前传输周期内的增益子周期下的第一增益系数，不再继续增加预设步长；如果在历史传输周期内网络丢包率不断上升，且接收速率保持动态稳定，而将在上一传输周期内的增益子周期下的第一增益系数减少预设步长时，需要保证减少后的第一增益系数不能低于系数调整下限，在上一传输周期内的增益子周期下的第一 增益系数减少预设步长后低于系数调整下限的情况下，直接将该系数调整下限作为当前传输周期内的增益子周期下的第一增益系数，不再继续减少，从而保证第一增益系数的调整准确性。
S360，根据第一增益系数，确定在当前传输周期内的减损子周期下的第二增益系数，并设置在当前传输周期内的平稳发送子周期下的第三增益系数。
S370，分别根据第一增益系数、第二增益系数和第三增益系数调整传输速率基值，得到在当前传输周期内的增益子周期、减损子周期和平稳发送子周期下的传输速率。
