Description

QoS处理及控制方法及网络接口控制器
本申请要求2019年06月10日递交的申请号为201910497729.7、发明名称为“QoS处理及控制方法及网络接口控制器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及数据转发技术领域，具体涉及一种QoS处理方法、装置及电子设备。本申请同时还涉及QoS控制方法、装置及电子设备。本申请同时还涉及一种网络接口控制器。
背景技术
随着网络应用的普及与推广，针对网络传输的数据流量进行QoS控制越来越重要，通过Qos控制能保障网络应用业务不被延迟或丢弃，提升用户体验。所谓QoS(Quality of Service，服务质量)，是为指定的网络通信提供更好的服务能力的网络技术。网络应用一般涉及服务器间的数据通信网络和服务器内系统总线互连网络(以下称系统总线互连网络)。所谓数据通信网络是指用于服务器间数据通信的网络，例如数据中心网络，已经有完善的QoS设置，用来降低流量间干扰，保障不同流量间的服务质量。系统总线互连网络也有类似的QoS机制，如PCIE总线支持TC和VC两级QoS机制，其中，所谓TC是指PCIE的TLP头部的TC(Traffic Class，流量类别)，取值范围0～7，值越大优先级越高，0优先级最低，表示总线事务层处理的服务质量分级。VC是PCIE总线的虚拟通道，PCIE总线设备将TC值映射到VC值进行数据传输。但是现有技术中存在的问题是，数据通信网络的QoS机制和系统总线互连网络的QoS机制处于完全隔离的状态，例如，在连接数据通信网络和系统总线互连网络的网络接口控制器(网卡)中，数据通信网络的QoS机制和系统总线互连网络的QoS机制是不连通的两个QoS域，在数据中心网络中得到高服务质量保障的流量，在服务器内部却可能只是最低服务质量保障，最终导致网络应用得不到所需的通信性能，无法实现端对端QoS控制。甚至，现有的设备在实现PCIE总线功能时未支持PCIE总线规范的全集，例如，所有流量均被映射至TC0(优先级最低)和VC0(优先级最低)，从而，系统总线互连网络的QoS体系完全缺失。
因此，如何消除数据通信网络和系统总线互连网络之间的QoS域隔离状态，是需要 解决的问题。

具体实施方式
在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似推广，因此本申请不受下面公开的具体实施的限制。
本申请提供一种QoS处理方法、装置及电子设备。本申请还提供一种QoS控制方法、装置及设备。本申请还提供一种网络接口控制器。在下面的实施例中逐一进行详细说明。
本申请第一实施例提供一种QoS处理方法，用于在系统总线互连网络的第一QoS域与数据通信网络的第二QoS域之间建立映射关系，将数据通信网络和系统总线互连网络之间的QoS域关联起来。
为便于理解，首先介绍系统总线互连网络与数据通信网络之间进行数据传输的网络环境。
请参考图1，图中，数据中心网络101为数据通信网络，具体是用于服务器间数据通信的网络，能够通过包含的网络转发设备给数据流量提供QoS控制，降低流量间干扰，保障不同流量间的服务质量。系统总线互连网络102是服务器内系统总线互连网络，即服务器内互连各种设备的通信总线构成的网络，所谓系统总线可以是PCIE总线、CCIX总线、OpenCAPI总线、GenZ总线、CXL总线，能够给在服务器内系统总线互连网络中传输的数据流量提供QoS控制，例如，采用PCIE总线的系统总线互连网络，一般包括 TC和VC两级QoS机制。网络接口控制器103用于在数据中心网络101和系统总线互连网络102之间传输数据，例如可以是连接数据通信网络和系统总线互连网络的网卡。网络接口控制器103通过通信队列(Queue Pair，缩写为QP)与数据中心网络101之间进行数据传输，并提供第一QoS域用于对网络接口控制器103与数据中心网络101之间传输的数据进行QoS控制，其中，通信队列可以为网卡上的硬件队列，网络接口控制器内有多个QP，一个Socket链接的通信可以由一个QP完成，如图中所示的QP0、QP1、…、QPn-1；网络接口控制器103通过流量类别队列(TC)与系统总线互连网络102的虚拟通道(VC)之间映射进行数据传输，并提供第二QoS域用于对网络接口控制器103与系统总线互连网络102之间传输的数据进行QoS控制。现有技术中，第一QoS域与第二QoS域处于隔离状态，因此针对在数据中心网络101和系统总线互连网络103之间传输的数据无法进行端对端QoS控制，在数据中心网络中得到高服务质量保障的流量，在服务器内部却可能只是最低服务质量保障。
以下结合图2对本申请第一实施例提供的所述QoS处理方法进行说明。
图2所示的QoS处理方法，包括：步骤S201至步骤S203。
步骤S201，获得针对系统总线互连网络的第一QoS配置数据。
所述第一QoS配置数据，为系统总线互连网络QoS配置信息，例如，可以是服务器内系统总线互连全局QoS配置信息，服务器内系统总线上连接的多个总线设备使用的全局QoS配置信息，如显示卡、声卡等总线设备使用全局QoS配置信息。
本步骤为获得针对系统总线互连网络的第一QoS配置数据。具体可以从连接数据通信网络与服务器内系统总线互连网络的网络接口控制器的配置信息中获得所述网络接口控制器与系统总线的接口上绑定的QoS配置信息。
步骤S202，获得针对数据通信网络的第二QoS配置数据。
所述第二QoS配置数据，为数据通信网络的QoS配置信息，例如，可以是数据中心网络全局QoS配置信息，数据中心网络的各转发设备使用的全局QoS配置信息，如路由器、交换机等交换设备针对指定流量使用相同的QoS配置信息。
本步骤是获得针对数据通信网络的第二QoS配置数据。具体可以从连接数据通信网络与服务器内系统总线互连网络的网络接口控制器的配置信息中获得所述网络接口控制器与数据通信网络的接口上绑定的QoS配置信息。

实际应用中，传输层QoS标签是标识传输层服务差异的标签，可以是系统总线事务层TLP包的TC字段；链路层QoS标签是标识链路层服务差异的标签，可以是系统总线链路层包头中的VC字段。数据通信网络网络层QoS标签可以是以太网网络层的qos标签，即IP包的DSCP值。

图11所示的网络流量调度方法，包括：步骤S1101至步骤S1104。
步骤S1101，获得针对系统总线互连网络的第一QoS配置数据。
所述第一QoS配置数据，为系统总线互连网络QoS配置信息，例如，可以是服务器内系统总线互连全局QoS配置信息，服务器内系统总线上连接的多个总线设备使用的全局QoS配置信息，如显示卡、声卡等总线设备使用全局QoS配置信息。
本步骤为获得针对系统总线互连网络的第一QoS配置数据。具体可以从连接数据通信网络与服务器内系统总线互连网络的网络接口控制器的配置信息中获得所述网络接口控制器与系统总线的接口上绑定的QoS配置信息。
步骤S1102，获得针对数据通信网络的第二QoS配置数据。

步骤S1103，根据所述第一QoS配置数据和所述第二QoS配置数据，建立所述系统总线互连网络的第一QoS域与所述数据通信网络的第二QoS域之间的映射关系。
本实施例中，通过下述处理建立所述系统总线互连网络的第一QoS域与所述数据通信网络的第二QoS域之间的映射关系：
根据所述第一QoS配置数据，获得用于存储所述数据的通信队列与系统总线互连网络传输层QoS标签之间的第一映射关系，以及系统总线互连网络传输层QoS标签与系统 总线互连网络链路层QoS标签之间的第二映射关系；
根据所述第二QoS配置数据，获得所述通信队列与数据通信网络网络层QoS标签之间的第三映射关系；
根据所述第一映射关系、所述第二映射关系以及所述第三映射关系，得到所述系统总线互连网络的第一QoS域与所述数据通信网络的第二QoS域之间的映射关系；其中，所述第一QoS域包括下述至少一种信息：系统总线互连网络传输层QoS标签、系统总线互连网络链路层QoS标签；所述第二QoS域包括：数据通信网络网络层QoS标签。
实际应用中，传输层QoS标签是标识传输层服务差异的标签，可以是系统总线事务层TLP包的TC字段；链路层QoS标签是标识链路层服务差异的标签，可以是系统总线链路层包头中的VC字段。数据通信网络网络层QoS标签可以是以太网网络层的qos标签，即IP包的DSCP值。
以网卡连接数据中心网络和服务器内的系统总线互连网络为例，将所述方法应用于网卡。网卡接受针对所述网卡与系统总线侧接口的总线互连全局QoS配置信息，从所述总线互连全局QoS配置信息中获取QP(即网卡通信队列)与SysTC之间的映射关系，其中SysTC是系统总线传输层QoS标签，将所述映射关系作为第一映射关系；从所述总线互连全局QoS配置信息中获取SysTC与SysVC之间的映射关系，其中，SysVC是系统总线链路层QoS标签；将所述映射关系作为第二映射关系。网卡接受针对与数据中心网络侧接口的全局QoS配置，从所述全局QoS配置中获取QP(即网卡通信队列)与DSCP(即IP包中的QoS域)间的映射关系，将所述映射关系作为第三映射关系。将第一映射关系、第二映射关系、第三映射关系作为所述第一QoS和第二QoS域这两种QoS体系之间的映射关系，即所述两种QoS体系之间的映射关系，包括：进入服务器内方向的网卡通信队列到网卡流量类别队列再到系统总线虚拟通道的QoS映射关系；出服务器进入数据通信网络方向的通信队列到IP包的DSCP的QoS映射关系。
本实施例的一个实施方式中，还包括根据数据通信网络的网络状态以及系统总线互连的网络状态两种信息中的至少一种信息调整系统总线互连网络的第一QoS域与数据通信网络的第二QoS域之间的映射关系。其中，数据通信网络的网络状态，包括网络延迟、拥塞状态中的至少一种状态信息；系统总线互连网络的网络状态，包括网络延迟、拥塞状态中的至少一种状态信息。具体包括下述处理：

步骤S1104，根据所述映射关系针对在所述数据通信网络和所述系统总线互连网络之间传输的数据流量进行调度。
本实施例中，根据所述映射关系，对所述数据流量进行调度，实现针对所述数据流量的端到端QoS控制。
本实施例的一种实施方式中，还包括将映射关系存储到表中。具体包括下述处理：
将所述第一映射关系存储到以所述通信队列的队列号为索引的第一映射关系表；将所述第二映射关系存储到第二映射关系表；将所述第三映射关系存储到以所述通信队列的队列号为索引的第三映射关系表。
进一步，所述第一映射关系表和第三映射关系表分别还包括用于存储非通信队列号索引的映射关系的预留映射区，所述非通信队列号索引的映射关系用于未与通信队列绑定的特定流量的流量控制。
沿用以网卡连接数据中心网络和服务器内的系统总线互连网络的例子。将QP与SysTC映射关系写入第一映射关系表；将SysTC与SysVC之间的映射关系写入第二映射关系表；将QP与DSCP的映射关系写入第三映射关系表。其中，第一映射关系表以及第二映射关系表用于对进入服务器内系统总线互连网络的数据进行QoS控制；第三映射关系表用于出服务器内系统总线互连网络进入服务器间数据通信网络的数据进行QoS控制。实际应用中，网卡的网络接口引擎读取映射关系表信息进行QoS映射，对于出服务器内系统总线互连网络进入服务器间数据通信网络的数据，离开服务器后由数据通信网络的交换设备例如交换机，进行DSCP到网络队列(NetVC)的映射，最终实现端对端QoS控制。
本实施例的一种实施方式中，具体通过下述处理对在所述数据通信网络和所述系统总线互连网络之间传输的数据包进行QoS控制：
查询第一映射关系表，获得第一映射关系；
根据所述第一映射关系查询第二映射关系表获得第二映射关系；

查询第三映射关系表，获得第三映射关系；
根据第三映射关系对由系统总线互连网络发往数据通信网络的数据包进行QoS控制。
需要说明的是，如果将进入服务器内系统总线互连网络的数据作为输入方向的数据，将出服务器内系统总线互连网络进入数据通信网络的数据作为输出方向的数据，则建立输入方向的QoS映射关系与建立输出方向的QoS映射关系可以分别单独实施，例如：
根据所述第一QoS配置数据，获得用于存储所述数据的通信队列与系统总线互连网络传输层QoS标签之间的第一映射关系，以及系统总线互连网络传输层QoS标签与系统总线互连网络链路层QoS标签之间的第二映射关系；将所述第一映射关系以及所述第二映射关系作为输入方向QoS映射关系；
根据所述第二QoS配置数据，获得所述通信队列与数据通信网络网络层QoS标签之间的第三映射关系；将所述第三映射关系作为输出方向QoS映射关系。
建立输入方向QoS映射关系和输出方向QoS映射关系中的至少一种映射关系，均属于本申请保护范围。甚至，在建立输入方向QoS映射关系中，建立第一映射关系和第二映射关系中的至少一种映射关系，均属于本申请保护范围。
