具体实施方式Detailed ways

此处所描述的具体实施例仅仅用以解释本申请。The specific embodiments described here are only used to explain the present application.

5G***提出网络切片概念。图1示出了一实施例提供的一种网络切片满足不同服务需求的网络架构示意图。3GPP对5G的典型场景归纳为以下三种：如图1所示，增强的移动宽带业务(enhanced Mobile Broadband，eMBB)，海量机器类型连接业务(massive Machine Type Communication，mMTC)以及超可靠低时延业务(Ultra Reliable and Low Latency Communications，URLLC)，URLLC也可以称为特定机器类型连接业务(Critical machine type communication)。其中，eMBB是指在移动宽带业务场景的基础上，对于用户体验等性能的提升，mMTC则主要针对物联网的应用场景，适用于大规模，低功耗，低成本，深度覆盖的物联网终端提供网络接入服务，而URLLC则面向对数据传输可靠性以及时延要求苛刻的业务，如车联网，工业控制等场景。三大场景中包含了多样化，差异性的服务，并非所有未来的用例都对速率，覆盖有较强的需求，因此，3GPP允许运营商通过独立网络功能集合与参数配置构建网络切片，用来服务多个以及虚拟运营商的需求，同时，3GPP要求可以根据不同的市场场景动态生成网络切片。The 5G system proposes the concept of network slicing. FIG. 1 shows a schematic diagram of a network architecture in which network slicing meets different service requirements provided by an embodiment. 3GPP’s typical 5G scenarios are summarized into the following three types: as shown in Figure 1, enhanced mobile broadband services (enhanced Mobile Broadband, eMBB), massive machine type connection services (massive Machine Type Communication, mMTC) and ultra-reliable low-latency Business (Ultra Reliable and Low Latency Communications, URLLC), URLLC can also be called a specific machine type connection business (Critical machine type communication). Among them, eMBB refers to the improvement of user experience and other performance on the basis of mobile broadband service scenarios, and mMTC is mainly aimed at application scenarios of the Internet of Things, suitable for large-scale, low-power, low-cost, and deep-coverage Internet of Things terminals Provides network access services, while URLLC is oriented to services that have strict requirements on data transmission reliability and delay, such as Internet of Vehicles, industrial control and other scenarios. The three major scenarios include diversified and differentiated services. Not all future use cases have strong requirements for speed and coverage. Therefore, 3GPP allows operators to build network slices through independent network function sets and parameter configurations for To serve the needs of multiple and virtual operators, at the same time, 3GPP requires that network slices can be dynamically generated according to different market scenarios.

网络切片可以实现QoS的隔离，灵活的网络管控与网络效率的提升。即可以为同一用户提供多个网络切片，不同的业务适用不同的网络切片，对于单一用户使用的终端设备，3GPP已经定义了本地业务如何映射到不同网络切片的策略。但是对于CPE来说，上述映射策略并不适用，这是因为：首先，CPE是个管道设备，其很难分辨出哪些业务要使用高优先级的网络切片，哪些业务要使用普通网络切片；其次，CPE的QoS功能比较简单，无法映射到网络切片，即使5G网络分给一个业务非常高的QoS，但是到了CPE后，又会导致所有业务的QoS基本一致了。这样即使5G网络分给高优先级业务再高的QoS，通过CPE后，QoS还是无法得到保障。Network slicing can realize QoS isolation, flexible network management and control, and improvement of network efficiency. It can provide multiple network slices for the same user, and different services are suitable for different network slices. For terminal equipment used by a single user, 3GPP has defined strategies for how local services are mapped to different network slices. But for CPE, the above mapping strategy is not applicable, because: first, CPE is a pipeline device, it is difficult to distinguish which services should use high-priority network slices, and which services should use ordinary network slices; secondly, The QoS function of the CPE is relatively simple and cannot be mapped to network slices. Even if the 5G network assigns a very high QoS to a service, the QoS of all services will be basically the same after reaching the CPE. In this way, even if the 5G network allocates higher QoS to high-priority services, the QoS cannot be guaranteed after passing through the CPE.

本申请实施例提供了一种报文处理方法、客户前置设备及计算机可读存储介质，能够在CPE端实现网络切片的映射，保证整条链路的QoS都满足业务的需求。The embodiment of the present application provides a packet processing method, a client front-end device, and a computer-readable storage medium, which can realize mapping of network slices on the CPE side, and ensure that the QoS of the entire link meets service requirements.

下面对报文处理方法、客户前置设备及其技术效果进行描述。The message processing method, customer front-end equipment and technical effects thereof are described below.

图2示出了一实施例提供的一种报文处理方法的流程示意图，如图2所示，本实施例提供的方法适用于CPE，该方法包括：Fig. 2 shows a schematic flowchart of a message processing method provided by an embodiment. As shown in Fig. 2, the method provided by this embodiment is applicable to a CPE, and the method includes:

S110、从CPE接入的至少两个网络切片处获取多条报文。S110. Obtain multiple messages from at least two network slices accessed by the CPE.

CPE可以从接入的至少两个网络切片处获取报文，以实现QoS的隔离。每条报文对应一个网络切片。报文的数量为多条。The CPE can obtain packets from at least two connected network slices to implement QoS isolation. Each packet corresponds to a network slice. The number of messages is multiple.

例如，CPE接入的网络切片的数量为2(分别记为网络切片1和网络切片2)，从网络切片1处获取了三条报文(分别记为报文1、报文2和报文3)，从网络切片2处获取了两条报文(分别记为报文4和报文5)。那么，报文1对应网络切片1，报文2对应网络切片1，报文3对应网络切片1，报文4对应网络切片2，报文5对应网络切片5。For example, the number of network slices accessed by the CPE is 2 (denoted as network slice 1 and network slice 2 respectively), and three messages are obtained from network slice 1 (denoted as message 1, message 2 and message 3 respectively). ), two packets (respectively denoted as packet 4 and packet 5) are obtained from network slice 2. Then, packet 1 corresponds to network slice 1, packet 2 corresponds to network slice 1, packet 3 corresponds to network slice 1, packet 4 corresponds to network slice 2, and packet 5 corresponds to network slice 5.

S120、确定每条报文的优先级参数。S120. Determine the priority parameter of each packet.

在一实施例中，优先级参数为差分服务代码点(Differentiated Services Code Point，DSCP)值。In one embodiment, the priority parameter is a Differentiated Services Code Point (DSCP) value.

DSCP值位于报文的网际互连协议(Internet Protocol，IP)头部的服务类别(Type Of Service，TOS)标识字节中，利用报文中已使用的6比特和未使用的2比特，通过编码值来区分报文的优先级。通常，DSCP值的范围为0-63。DSCP值越大，表示报文的优先级越高；DSCP值越小，表示报文的优先级越低。The DSCP value is located in the Class of Service (Type Of Service, TOS) identification byte of the Internet Protocol (Internet Protocol, IP) header of the message, using the used 6 bits and the unused 2 bits in the message, through Encoding value to distinguish the priority of the message. Typically, DSCP values range from 0-63. The larger the DSCP value, the higher the priority of the packet; the smaller the DSCP value, the lower the priority of the packet.

S120中“确定每条报文的优先级参数”的方法可以包括如下任意一个：The method of "determining the priority parameter of each message" in S120 may include any one of the following:

1.在每条报文中预置有该条报文的DSCP值的情况下，维持该条报文的DSCP值不变。1. In the case where the DSCP value of the message is preset in each message, the DSCP value of the message is kept unchanged.

2.在每条报文中未预置有该条报文的DSCP值的情况下，根据该条报文对应的网络切片的优先级，设置该条报文的DSCP值。2. If the DSCP value of the message is not preset in each message, set the DSCP value of the message according to the priority of the network slice corresponding to the message.

在根据每条报文对应的网络切片的优先级，设置该条报文的DSCP值时，该条报文对应的网络切片的优先级越高，设置的该条报文的DSCP值越大；该条报文对应的网络切片的优先级越低，设置的该条报文的DSCP值越小。When setting the DSCP value of the message according to the priority of the network slice corresponding to each message, the higher the priority of the network slice corresponding to the message, the larger the DSCP value of the message is set; The lower the priority of the network slice corresponding to the message, the smaller the DSCP value of the message is set.

对于未预置有DSCP值的多条报文，对应同一个网络切片的多条报文的设置后的DSCP值相等。For multiple packets without preset DSCP values, the set DSCP values of multiple packets corresponding to the same network slice are equal.

在一实施例中，若一条报文不具有可用令牌，则丢弃该条报文；若一条报文具有可用令牌，则对该条报文进行流量整形。In an embodiment, if a message does not have an available token, the message is discarded; if a message has an available token, traffic shaping is performed on the message.

在确定每条报文的优先级参数后，还可以根据每条报文的IP五元组，以及每条报文来自哪个切片，对多条报文进行分类，放入对应的令牌桶；当令牌桶中没有令牌，说明该类报文的速率过大，需要丢弃该类报文；若令牌桶中有令牌，说明该类报文可以正常处理，需要对该类报文进行流量整形(又称流量限速)。After determining the priority parameters of each message, multiple messages can be classified and put into the corresponding token bucket according to the IP quintuple of each message and which slice each message comes from; When there is no token in the token bucket, it means that the rate of this type of message is too high, and this type of message needs to be discarded; if there is a token in the token bucket, it means that this type of message can be processed normally, and this type of message needs to be Perform traffic shaping (also known as traffic rate limiting).

流量整形的目的是为了限制一类报文的速率，防止该类报文的速率过大，影响其他类型的报文。The purpose of traffic shaping is to limit the rate of a type of packet, preventing the rate of this type of packet from being too high and affecting other types of packets.

S130、将从同一个网络切片处获取的所有报文放入同一个队列中，并按照网络切片的优先级顺序，依次处理对应队列中的报文，在同一个队列中存在多条报文的情况下，按照每条报文的优先级参数确定该多条报文的处理顺序。S130. Put all the messages obtained from the same network slice into the same queue, and process the messages in the corresponding queues sequentially according to the priority order of the network slices, if there are multiple messages in the same queue In this case, the processing order of the multiple messages is determined according to the priority parameter of each message.

在一实施例中，网络切片的优先级根据网络切片的QoS确定。In one embodiment, the priority of the network slice is determined according to the QoS of the network slice.

例如，CPE接入的网络切片的数量为2(分别记为网络切片1和网络切片2)，网络切片1的优先级高于网络切片2的优先级。CPE从网络切片1处获取了三条报文(分别记为报文1、报文2和报文3)，从网络切片2处获取了两条报文(分别记为报文4和报文5)。那么，CPE将报文1、报文2和报文3放入队列1中，将报文4和报文5放入队列2中，然后先处理队列1中的三条报文，再处理队列2中的两条报文。For example, the number of network slices accessed by the CPE is 2 (denoted as network slice 1 and network slice 2 respectively), and the priority of network slice 1 is higher than that of network slice 2. The CPE obtained three packets from network slice 1 (denoted as packet 1, packet 2, and packet 3), and obtained two packets from network slice 2 (respectively recorded as packet 4 and packet 5). ). Then, the CPE puts packet 1, packet 2, and packet 3 into queue 1, puts packet 4 and packet 5 into queue 2, and then processes the three packets in queue 1 first, and then processes queue 2. two messages in .

针对同一个队列中的多条报文，按照每条报文的优先级参数确定该多条报文的处理顺序。假设任意一个队列为预设队列，S130中“依次处理对应队列中的报文”包括处理预设队列中的报文，对应的方法可以包括：For multiple messages in the same queue, the processing order of the multiple messages is determined according to the priority parameter of each message. Assuming that any queue is a preset queue, "sequentially processing the messages in the corresponding queue" in S130 includes processing the messages in the preset queue, and the corresponding method may include:

一.根据预设队列中的多条报文的DSCP值，将该多条报文放入N个子队列中，N为大于或者等于2的整数。1. Put the multiple messages into N subqueues according to the DSCP values of the multiple messages in the preset queue, where N is an integer greater than or equal to 2.

通常，N的取值为4；四个子队列分别为：语音接入子队列、视频接入子队列、尽力接入子队列和后台接入子队列。Usually, the value of N is 4; the four sub-queues are: a voice access sub-queue, a video access sub-queue, a best-effort access sub-queue and a background access sub-queue.

N的取值为4；根据预设队列中的多条报文的DSCP值，将该多条报文放入N个子队列中的方法包括：The value of N is 4; according to the DSCP value of multiple messages in the preset queue, the method of putting the multiple messages into N sub-queues includes:

1.在一条报文的DSCP值小于或者等于第一阈值的情况下，将该条报文放入第一子队列中；2.在一条报文的DSCP值大于第一阈值、且小于或者等于第二阈值的情况下，将该条报文放入第二子队列中；3.在一条报文的DSCP值大于第二阈值、且小于或者等于第三阈值的情况下，将该条报文放入第三子队列中；4.在一条报文的DSCP值大于第三阈值的情况下，将该条报文放入第四子队列中。1. When the DSCP value of a message is less than or equal to the first threshold, put the message into the first subqueue; 2. When the DSCP value of a message is greater than the first threshold and less than or equal to In the case of the second threshold, put the message into the second sub-queue; 3. When the DSCP value of a message is greater than the second threshold and less than or equal to the third threshold, put the message Put into the third sub-queue; 4. When the DSCP value of a message is greater than the third threshold, put the message into the fourth sub-queue.

二.按照N个子队列的优先级顺序，依次处理N个子队列中的多条报文。2. Process the multiple messages in the N sub-queues sequentially according to the priority order of the N sub-queues.

通常，N的取值为4；四个子队列分别为：语音接入子队列、视频接入子队列、尽力接入子队列和后台接入子队列，其中，语音接入子队列的优先级最高，其次是视频接入子队列的优先级，然后是尽力接入子队列的优先级，后台接入子队列的优先级最低。Usually, the value of N is 4; the four sub-queues are: voice access sub-queue, video access sub-queue, best-effort access sub-queue and background access sub-queue, among which the voice access sub-queue has the highest priority , followed by the priority of the video access sub-queue, then the priority of the best-effort access sub-queue, and the lowest priority of the background access sub-queue.

如此，能够在CPE端实现网络切片的映射，保证整条链路的QoS都满足业务的需求。In this way, the mapping of network slices can be realized on the CPE side, ensuring that the QoS of the entire link meets service requirements.

示例性的，假设CPE接入网络切片A和网络切片B，CPE从接入的网络切片A处获取报文1-报文6，CPE从接入的网络切片B处获取报文7-报文10。表1示出了报文和网络切片的对应关系及报文的初始DSCP值。Exemplarily, assuming that the CPE accesses network slice A and network slice B, the CPE obtains packet 1-packet 6 from the connected network slice A, and the CPE obtains packet 7-packet from the connected network slice B. 10. Table 1 shows the correspondence between packets and network slices and the initial DSCP value of packets.

表1Table 1

报文message	初始DSCP值initial DSCP value	所属网络切片Belonging network slice
报文1message 1	无none	网络切片ANetwork slice A
报文2message 2	5050	网络切片ANetwork slice A
报文3message 3	4545	网络切片ANetwork slice A
报文4message 4	2626	网络切片ANetwork slice A

报文8message 8	无none	网络切片BNetwork slice B
报文9message 9	无none	网络切片BNetwork slice B

报文10message 10	无none	网络切片BNetwork slice B

CPE获取到这10条报文后，首先在确定这10条报文的DSCP值。如表1所示，报文2、报文3和报文4中预置有DSCP值，因此保持报文2、报文3和报文4的DSCP值不变；报文1、报文6-报文10中未预置有DSCP值，因此，CPE要为这些报文设置DSCP值。After obtaining the 10 messages, the CPE first determines the DSCP values of the 10 messages. As shown in Table 1, DSCP values are preset in message 2, message 3 and message 4, so keep the DSCP values of message 2, message 3 and message 4 unchanged; message 1, message 6 - There is no DSCP value preset in the message 10, therefore, the CPE needs to set the DSCP value for these messages.

由于报文1和报文6对应的网络切片A，网络切片A的优先级高于网络切片B的优先级，因此，根据网络切片A的优先级，设置报文1和报文6的DSCP值为60；根据网络切片B的优先级，设置报文7-报文10的DSCP值为10。表2示出了报文和网络切片的对应关系及报文设置后的DSCP值。Since packet 1 and packet 6 correspond to network slice A, the priority of network slice A is higher than that of network slice B. Therefore, according to the priority of network slice A, set the DSCP value of packet 1 and packet 6. is 60; according to the priority of network slice B, set the DSCP value of packet 7-packet 10 to 10. Table 2 shows the correspondence between packets and network slices and the DSCP value after the packets are set.

表2Table 2

CPE接入的网络切片的数量为2，此时创建两个队列，根据报文的IP五元组以及报文来自哪个切片，将报文1-报文6放入队列1中、将报文7-报文10放入队列2中。由于网络切片A的优先级高于网络切片B的优先级，因此先发送队列1中的报文到CPE的wifi层进行处理，当队列1中的报文都处理完后，再发送队列2中的报文到CPE的wifi层进行处理。The number of network slices accessed by the CPE is 2. At this time, two queues are created. According to the IP quintuple of the packet and which slice the packet comes from, the packets 1-6 are put into queue 1, and the packet 7-Packet 10 is put into queue 2. Since the priority of network slice A is higher than that of network slice B, the packets in queue 1 are first sent to the wifi layer of the CPE for processing. After the packets in queue 1 are all processed, they are sent to queue 2. The packets are sent to the wifi layer of the CPE for processing.

在对队列1中的报文进行处理时，首先根据报文1-报文6的DSCP值，将报文1-报文6放入4个子队列中。表3示出了报文1-报文6的DSCP值与子队列的对应关系。When processing the packets in queue 1, firstly, according to the DSCP values of packets 1 to 6, put packets 1 to 6 into four subqueues. Table 3 shows the correspondence between the DSCP values of packets 1-6 and subqueues.

表3table 3

报文message	DSCP值DSCP value	所属子队列belongs to the subqueue
报文1message 1	6060	AC_VOAC_VO
报文2message 2	5050	AC_VOAC_VO
报文3message 3	4545	AC_VIAC_VI
报文4message 4	2626	AC_BEAC_BE
报文5message 5	22	AC_BGAC_BG
报文6message 6	6060	AC_VOAC_VO

如表3所示，假设第一阈值为15，第二阈值为31，第三阈值为47。As shown in Table 3, assume that the first threshold is 15, the second threshold is 31, and the third threshold is 47.

报文1、报文2和报文6的DSCP值大于第三阈值47，将报文1、报文2和报文6放入语音接入子队列AC_VO中；报文3的DSCP值大于第二阈值31、且小于第三阈值47，将报文3放入视频接入子队列AC_VI中；报文4的DSCP 值大于第一阈值15、且小于第二阈值31，将报文4放入尽力接入子队列AC_BE中；报文5的DSCP值小于第一阈值15，将报文5放入后台接入子队列AC_BG中。The DSCP value of message 1, message 2 and message 6 is greater than the third threshold 47, and the message 1, message 2 and message 6 are put into the voice access subqueue AC_VO; the DSCP value of message 3 is greater than the third threshold Second threshold 31, and less than the third threshold 47, put message 3 into the video access sub-queue AC_VI; the DSCP value of message 4 is greater than the first threshold 15, and less than the second threshold 31, put message 4 into Best-effort access to the sub-queue AC_BE; the DSCP value of the packet 5 is less than the first threshold 15, and the packet 5 is put into the background access sub-queue AC_BG.

因此，在处理队列1中的报文时，首先处理语音接入子队列AC_VO中的报文1、报文2和报文6；然后处理视频接入子队列AC_VI中的报文3；再处理尽力接入子队列AC_BE中的报文4；最后处理后台接入子队列AC_BG中的报文5。Therefore, when processing the message in the queue 1, first process the message 1, message 2 and message 6 in the voice access sub-queue AC_VO; then process the message 3 in the video access sub-queue AC_VI; then process Best-effort access to message 4 in sub-queue AC_BE; finally process background access to message 5 in sub-queue AC_BG.

处理完队列1中的报文后，对队列2中的报文进行处理。首先根据报文7-报文10的DSCP值，将报文7-报文10放入4个子队列中。表4示出了报文7-报文10的DSCP值与子队列的对应关系。After the packets in queue 1 are processed, the packets in queue 2 are processed. Firstly, according to the DSCP values of the packets 7-10, put the packets 7-10 into 4 sub-queues. Table 4 shows the correspondence between the DSCP values of packets 7-10 and subqueues.

表4Table 4

报文message	DSCP值DSCP value	所属子队列belongs to the subqueue
报文7message 7	1010	AC_BGAC_BG
报文8message 8	1010	AC_BGAC_BG
报文9message 9	1010	AC_BG AC_BG

报文10message 10	1010	AC_BGAC_BG

如表4所示，假设第一阈值为15，第二阈值为31，第三阈值为47。As shown in Table 4, assume that the first threshold is 15, the second threshold is 31, and the third threshold is 47.

报文7-报文10的DSCP值均相等，报文7-报文10的DSCP值小于第一阈值15，将报文7-报文10放入后台接入子队列AC_BG中。The DSCP values of the packets 7-10 are equal, and the DSCP values of the packets 7-10 are smaller than the first threshold 15, and the packets 7-10 are put into the background access sub-queue AC_BG.

因此，在处理队列2中的报文时，由于语音接入子队列AC_VO、视频接入子队列AC_VI和尽力接入子队列AC_BE中均没有报文，此时直接处理后台接入子队列AC_BG中的报文7-报文10即可。Therefore, when processing packets in queue 2, since there are no packets in the voice access sub-queue AC_VO, video access sub-queue AC_VI, and best-effort access sub-queue AC_BE, the background access sub-queue AC_BG is directly processed at this time. The message 7-message 10 is enough.
