相关申请的交叉引用
本申请要求在2022年11月22日提交中国专利局、申请号为202211474087.7、申请名称为“一种信息处理方法及装置、存储介质”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
本申请涉及信息处理技术领域，涉及但不限于一种信息处理方法及装置、存储介质。
背景技术
容器编排管理平台(kubernetes，K8S)上的服务对外暴露有ClusterIP、NodePort以及负载均衡器等，以通过这些服务方式实现数据访问请求的负载均衡过程。
相关技术中，数据访问请求和其对应的响应信息会经过同一个具有转发程序的计算节点，在数据访问请求数量增加的情况下，对应的响应信息的数量也会对应增加，但是K8s中的计算节点数量有限，在数据访问请求和响应信息的数量大的情况下，会增加包含转发程序的计算节点的带宽，从而降低计算节点处理数据访问请求时的速度。
发明内容
为解决上述技术问题，本申请实施例期望提供一种信息处理方法及装置、存储介质，能够提高数据访问请求的处理速度。
本申请的技术方案是这样实现的：
本申请实施例提供一种信息处理方法，应用于第一信息处理装置，所 述信息处理方法包括：

调整部分，配置于利用所述请求转发地址和所述第二地址调整所述第二数据访问请求，得到第一数据访问请求；

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
现有技术中：如图1(a)所示，ClusterIP仅限在k8s集群内的工作负 载可访问，通过在计算节点上部署转发程序，将计算节点上的工作负载发出的请求转发到其它节点上的工作负载上。如图2(a)所示：ClusterIP的方式，只能在集群内可访问。
如图1(b)所示：NodePort方式同样是在计算节点上部署转发程序，k8s集群外的工作负载(请求端)可以访问工作负载所在的计算节点IP和分配的port，由计算节点上的转发程序将访问请求转发到集群内的工作负载上。如图2(b)所示：采用NodePort的方式，请求和响应数据都需要经过计算节点，对于需要大量数据传输的请求，会影响计算节点的带宽，消耗计算点的计算性能，同时需要额外引入高可用机制，如利用服务主动健康检查探测的机制切换DNS等，横向水平扩展能力不好，同时需要从计算节点分配TCP端口，受限于端口数量，支持的服务数有限。
如图1(c)所示：负载均衡器(LB)是指依赖传统的负载均衡设备，给k8s集群内的service分配一个服务IP和端口，Client端的请求先到负载均衡器，由负载均衡器将请求转发到k8s集群内的工作负载上。如图2(c)所示：采用负载均衡方式，不管是集群外还是集群内的请求和响应都需要经过它进行中转，时延比较高，由于东西向的工作负载间的流量比较大，需要更大处理能力的负载均衡服务集群，导致成本比较高。
针对现有技术中的不足，可以采用以下实施例中的方法进行解决。
申请实施例提供了一种信息处理方法，一种信息处理方法应用于第一信息处理装置，图3为本申请实施例提供的一种信息处理方法流程图，如图3所示，信息处理方法可以包括：
S101、在接收到第二信息处理装置传输的第一数据访问请求的情况下，解析第一数据访问请求，得到请求转发地址和第一地址；请求转发地址为第二信息处理装置的地址。
本申请实施例提供的一种信息处理方法适用于对K8s中的数据访问请 求进行负载均衡的场景下。
在本申请实施例中，第一信息处理装置可以以各种形式来实施。例如，本申请中描述的第一信息处理装置可以包括诸如手机、照相机、平板电脑、笔记本电脑、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、便捷式媒体播放器(Portable Media Player，PMP)、导航装置、可穿戴设备、智能手环、计步器等装置，以及诸如数字TV、台式计算机、服务器等装置。
在本申请实施例中，第一信息处理装置为K8s内的计算节点，第二信息处理装置可以为客户端(即K8s集群外的计算节点)，第二信息处理装置也可以为K8s内的计算节点(即除第一信息处理装置外的其他计算节点)；具体的第二信息处理装置可以根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，若第二信息处理装置为K8s内除第一信息处理装置外的其他计算节点，则第一数据访问请求可以为第二信息处理装置生成的请求；或者第一数据访问请求为通过第二信息处理装置将客户端生成的第二数据访问请求转发至第一信息处理装置中的请求。
在本申请实施例中，第一信息处理装置中包括地址转换模块(ReqMux-NAT-Agent)，用于解析第一数据访问请求，得到第一地址和请求转发地址。
在本申请实施例中，若第一数据访问请求为通过第二信息处理装置将客户端生成的第二数据访问请求转发至第一信息处理装置中的请求，则第一地址为客户端的地址。
在本申请实施例中，若第一数据访问请求为第二信息处理装置生成的请求，则第一信息处理装置在接收到第一数据访问请求的情况下，解析第一数据访问请求，得到的请求转发地址和第一地址相同，都为第二信息处理装置的地址。
需要说明的是，第一地址可以为网际互联协议(Internet Protocol，IP)/传输控制协议(Transmission Control Protocol，TCP)地址，第一地址还可以为其他的地址；具体的第一地址可以根据实际情况进行确定，本申请实施例对此不作限定。
需要说明的是，请求转发地址可以为IP/TCP地址；请求转发地址也可以为其他的地址；具体的请求转发地址可以根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，地址转换模块部署在K8s集群内的每一个计算节点中。
在本申请实施例中，第一数据访问请求可以是任意数据的访问请求；具体的第一数据访问请求可以根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，第一信息处理装置解析第一数据访问请求的方式为现有的技术方式；具体的可以根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，第一信息处理装置在接收到第二信息处理装置传输的第一数据访问请求的情况下，解析第一数据访问请求，得到第一地址和请求转发地址的过程，包括：第一信息处理装置在接收到第一数据访问请求、且第一数据访问请求中携带预设标识的情况下，解析第一数据访问请求，得到第一地址和请求转发地址。
在本申请实施例中，第一数据访问请求中携带预设标识可以为：第一数据访问请求中的IP选项中的预设标识字段的标识为预设标识。
需要说明的是，预设标识可以为未被分配使用标识，预设标识遵守请求评论(Request for Comments，RFC)规定。
示例性的，预设标识可以为code，预设标识也可以为其他的标识；具体的预设标识可以根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，第一数据访问请求包括IP头和IP报文，IP报文中的IP选项中记录有请求的目的地址(对于发送至第二信息处理装置中的第一数据访问请求，其目的地址为第二信息处理装置的地址)。具体的，IP选项由code、length和value三个字段组成，其中，value中的信息为请求转发地址，length中的信息为Value中信息的长度值；code为预设标识。
在本申请实施例中，第一信息处理装置解析第一数据访问请求，得到第一地址和请求转发地址之后，第一信息处理装置还会建立第一地址、第二地址和请求转发地址之间的第一对应关系。
需要说明的是，第二地址为实际处理第一数据访问请求生成对应的响应信息的装置，即为第一信息处理装置的地址。
需要说明的是，第一地址包括客户端的源IP和源端口(Port)；第二地址包括第一信息处理装置的目的IP和目的端口(Port)。
在本申请实施例中，第一信息处理装置还会从第一数据访问请求中获取传输层协议，如传输控制协议(Transmission Control Protocol，TCP)/用户数据报协议(User Datagram Protocol，UDP)。
在本申请实施例中，第一信息处理装置以第一地址、第二地址和传输层协议为key，以请求转发地址为对应的value值，从而得到k-v键值对，即得到第一对应关系。
S102、根据第一数据访问请求生成对应的响应信息。
在本申请实施例中，第一信息处理装置解析第一数据访问请求，得到请求转发地址和第一地址之后，第一信息处理装置就根据第一数据访问请求生成对应的响应信息。
在本申请实施例中，第一信息处理装置根据第一数据访问请求生成对应的响应信息的过程为现有技术，本申请实施例对此不作限定。
S103、将响应信息中的第二地址修改为请求转发地址，得到更新后的响应信息；第二地址为第一信息处理装置的地址。
在本申请实施例中，第一信息处理装置根据第一数据访问请求生成对应的响应信息之后，第一信息处理装置就将响应信息中的第二地址修改为请求转发地址，得到更新后的响应信息。
在本申请实施例中，第一信息处理装置可以将响应信息中的第二地址删除，并在第二地址的位置处写入请求转发地址，从而得到了更新后的响应信息；第一信息处理装置将响应信息中的第二地址修改为请求转发地址得到更新后的响应信息的具体实施方式，可以根据实际情况进行确定，本申请实施例对此不作限定。
在本申请实施例中，第一信息处理装置将响应信息中的第二地址修改为请求转发地址，得到更新后的响应信息的过程，包括第一信息处理装置获取响应信息的目的发送地址、响应信息中携带的第二地址、请求转发地址；建立目的发送地址、与第二地址，请求转发地址之间的第二对应关系；在第一对应关系与第二对应关系匹配的情况下，将响应信息中的第二地址修改为请求转发地址，得到更新后的响应信息。
在本申请实施例中，生成的响应信息中携带有第二地址。
在本申请实施例中，第一信息处理装置建立目的发送地址、第二地址和请求转发地址之间的第二对应关系的方式，与信息处理装置建立第一地址、第二地址和请求转发地址之间的第一对应关系的方式相同。
在本申请实施例中，第一信息处理装置在确定出第一关系中的请求转发地址和第二关系中的请求转发地址相同、第一关系中的第二地址与第二关系中的第二地址相同、第一关系中的第一地址与第二关系中的目的发送地址相同的情况下，第一信息处理装置就确定第一对应关系与第二对应关系匹配。
S104、向第一地址对应的客户端传输更新后的响应信息。
在本申请实施例中，第一信息处理装置将响应信息中的第二地址修改为请求转发地址，得到更新后的响应信息之后，第一信息处理装置就向第 一地址对应的客户端传输更新后的响应信息。
在本申请实施例中，ReqMux-NAT-Agent用于解析发往第一信息处理装置中的IP报文(第一数据访问请求由多条IP报文组成)，如果在IP报文的IP选项中包括code字段，则解析该字段，得到经第二信息处理装置中的请求分发模块(ReqMux)修改前的请求转发地址，并生成一条记录，记录的key为从IP报文中提取的五元组信息(源IP，源端口，目的IP，目的端口，传输层协议)，记录的value值为请求转发地址，从而得到第一对应关系。对于第一信息处理装置发送的IP报文，也按照上述方法提取五元组信息，得到第二对应关系，查找是否存在记录(确定第一对应关系与第二对应关系是否匹配)，如果存在(第一对应关系与第二对应关系匹配)则将响应信息中的第二地址修改为请求转发地址，得到更新后的响应信息。
示例性的，如图4所示：ReqMux-NAT-Agent分2个部分，如图4中的②所示，对于发往第一信息处理装置的报文，通过操作系统的HOOK机制，将程序逻辑串联到操作系统协议栈对发往第一信息处理装置的报文处理链路上(LocalIN)，通过设置优先级，对于发往第一信息处理装置的报文，优先执行地址转换(DNAT，目的地址转换)程序，例如linux系统，利用netfilter框架，在PREROUTING链上注册钩子函数，解析入方向的IP报文(解析接收到的报文或者是生成的报文)，如果IP报文的IP选项中包括code字段，则解析该字段，得到经第二信息处理装置中的ReqMux修改前的请求转发地址，并生成一条记录，记录的key为从IP报文中提取的五元组信息(源IP，源端口，目的IP，目的端口，传输层协议)，记录的value值为请求转发地址，从而得到第一对应关系。另一个部分是对于第一信息处理装置发出的报文，如图4中的③所示，通过操作系统的HOOK机制，将程序逻辑串联到操作系统协议栈对发往第一信息处理装置的报文处理链路上(LocalOut)，通过设置优先级，对于发往第一信息处理装置的报文，优先执行本程序，例如linux系统，利用netfilter框架，在POSTROUTING 链上注册钩子函数，提取五元组信息，得到第二对应关系，查找②中保存的信息(确定第一对应关系与第二对应关系是否匹配)，若找到(即第一对应关系与第二对应关系匹配)，则将响应信息中的第二地址修改为请求转发地址(SNAT，源地址转换)，得到更新后的响应信息。
可以理解的是，第一信息处理装置通过解析第一数据访问请求，得到客户端的第一地址和请求转发地址，将响应信息中的第二地址修改为请求转发地址，使得客户端可以根据请求转发地址认为更新后的响应信息为第二信息处理装置发送的，可以直接识别该更新后的响应信息，从而不需要再利用第二信息处理装置按照数据访问请求的传输反路径、将响应信息传输至客户端，在数据访问请求和响应信息的数量大的情况下，降低了信息处理装置的带宽、即降低了计算节点的带宽，同时提高了数据访问请求的处理速度。
本申请实施例又提供了一种信息处理方法，应用于第二信息处理装置，图5为本申请实施例提供的一种应用于第二信息处理装置中的信息处理方法流程图，如图5所示，信息处理方法可以包括：
S201、在接收到客户端传输的第二数据访问请求的情况下，从第二数据访问请求中获取请求转发地址。
本申请实施例提供的一种信息处理方法适用于对K8s中的数据访问请求进行负载均衡的场景下。
在本申请实施例中，第二信息处理装置可以以各种形式来实施。例如，本申请中描述的第二信息处理装置可以包括诸如手机、照相机、平板电脑、笔记本电脑、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、便捷式媒体播放器(Portable Media Player，PMP)、导航装置、可穿戴设备、智能手环、计步器等装置，以及诸如数字TV、台式计算机、服务器等装置。
在本申请实施例中，第二信息处理装置中携带有请求分发模块(ReqMux)，用于对客户端传输的至第二信息处理装置中的第二数据访问请求或者是第二信息处理装置生成的第二数据访问请求进行处理，得到第一数据访问请求，并发送至第一信息处理装置中。
在本申请实施例中，ReqMux部署在K8s集群内的每一个计算节点中。
在本申请实施例中，客户端为K8s集群外的计算节点，第二信息处理装置为K8s集群内除第一信息处理装置外的其他计算节点。
在本申请实施例中，若第二数据访问请求为第二信息处理装置生成的请求，则在第二信息处理装置生成第二数据访问请求的情况下，第二信息处理装置就根据请求转发地址(即为第二信息处理装置的地址，第二信息处理装置生成的第二数据访问请求中携带有请求转发地址)确定第一信息处理装置，并获取第一信息处理装置的第二地址；利用请求转发地址和第二地址调整第二数据访问请求，得到第一数据访问请求；向第一信息处理装置发送第一数据访问请求。
在本申请实施例中，第二数据访问请求中携带有请求转发地址和客户端的第一地址。其中，第一地址为客户端的地址。
需要说明的是，第一地址可以为IP/TCP地址，第一地址还可以为其他的地址；具体的第一地址可以根据实际情况进行确定，本申请实施例对此不作限定。

在本申请实施例中，第二信息处理装置利用请求转发地址和第二地址调整第二数据访问请求，得到第一数据访问请求之后，第二信息处理装置就向第一信息处理装置发送第一数据访问请求。
在本申请实施例中，ReqMux用于接收第二数据访问请求并匹配请求的请求转发地址(ip，port)，匹配上后，根据请求转发地址确定第一信息处理装置(后端服务器)，修改第二数据访问请求的报文头(IP头和TCP头)，将请求转发地址的对应的IP和TCP端口修改成第一信息处理装置的IP和服务端口，并在第二数据访问请求的IP报文的IP选项中记录目的请求地址(即第一信息处理装置的地址)。
示例性的，ReqMux可以通过操作系统的HOOK机制，将程序逻辑串联到操作系统协议栈对发往第二信息处理装置的报文处理链路上，通过设置优先级，对于发往第二信息处理装置中的报文，优先执行请求分发程序，例如linux系统，利用netfilter框架，在LOCAL_IN链上注册钩子函数。对所有发往第二信息处理装置的报文，获取报文的请求转发地址(IP和端口号)，通过IP和端口号查找暴露的服务列表，如果找到就通过一致性哈希算法(例如maglev consistent hash算法)选择一个后端服务器(工作负载，也即第一信息处理装置)，修改第二数据访问请求的报文头，将请求转发地址的对应的IP和TCP端口修改成第一信息处理装置的IP和服务端口(DNAT)，并在IP报文的IP选项中记录请求转发地址(ip，port)，IP选项由code，length,value三个字段组成，value字段的值为请求转发地址，length字段的值为Value中信息的长度值；code为预设标识，遵从IPv4RFC和IPv6RFC协议，预设标识为私有的code并且在组织内部不与其它程序冲突。
示例性的，如图6所示：集群外的客户端(工作负载：10.1.2.3)将第二数据访问请求传输至K8s集群内的第二信息处理装置(计算节点1)；第二信息处理装置(中的ReqMux)从第二数据访问请求中获取请求转发地址(172.1.2.1:80)；根据请求转发地址确定第一信息处理装置，并获取第一信息处理装置的第二地址(192.168.1.3:8080)；根据第二地址确定第一报文头；利用第一报文头修改第二数据访问请求中的第二报文头，得到第三 数据访问请求；在第三数据访问请求中添加请求转发地址，得到第一数据访问请求；向第一信息处理装置发送第一数据访问请求。第一信息处理装置(计算节点2)在接收到第二信息处理装置传输的第一数据访问请求的情况下，第二信息处理装置中的ReqMux-NAT-Agent解析第一数据访问请求，得到第一地址和请求转发地址；根据第一数据访问请求生成对应的响应信息；ReqMux-NAT-Agent将响应信息中的第二地址修改为请求转发地址，得到更新后的响应信息；向第一地址对应的客户端(工作负载：10.1.2.3)传输更新后的响应信息。
示例性的，如图7所示：K8s集群内的第二信息处理装置(计算节点1)生成了第二数据访问请求的情况下，第二信息处理装置就根据请求转发地址(即为第二信息处理装置的地址)确定第一信息处理装置，并获取第一信息处理装置的第二地址；利用请求转发地址和第二地址调整第二数据访问请求，得到第一数据访问请求；向第一信息处理装置发送第一数据访问请求。K8s集群内的第一信息处理装置(计算节点2)在接收到第二信息处理装置传输的第一数据访问请求的情况下，第二信息处理装置中的ReqMux-NAT-Agent解析第一数据访问请求，得到第一地址和请求转发地址；此时第一地址和请求转发地址相同，根据第一数据访问请求生成对应的响应信息；ReqMux-NAT-Agent将响应信息中的第二址修改为请求转发地址，得到更新后的响应信息；向第一地址对应的客户端(工作负载：10.1.2.3)传输更新后的响应信息。
可以理解的是，第二信息处理装置在接收到客户端传输的第二数据访问请求的情况下，利用请求转发地址和第二地址调整第二数据访问请求，得到第一数据访问请求，即在第二数据访问请求中添加请求转发地址和第二地址，以供第一信息处理装置将响应信息中的第二地址修改为请求转发地址，使得客户端可以根据请求转发地址认为更新后的响应信息为第二信息处理装置发送的，可以直接识别该更新后的响应信息，从而不需要再利 用第二信息处理装置按照数据访问请求的传输反路径、将响应信息传输至客户端，在数据访问请求和响应信息的数量大的情况下，降低了信息处理装置的带宽、即降低了计算节点的带宽，同时提高了数据访问请求的处理速度。
