技术领域 Technical field

本发明涉及通信技术领域，具体涉及一种网络丟包信息报告方法及装置。 The present invention relates to the field of communications technologies, and in particular, to a network packet loss information reporting method and apparatus.

背景技术 Background technique

网络丟包是常见的网络故障，包括节点拥塞丟包、链路时延抖动丟包等，会严重影响用户体验。其中，对于节点拥塞丟包，发生丟包的节点虽然知道发生了丟包，但往往不能识别被丟弃报文的业务类型和用户，也没有办法将丟包信息传递出去。例如图 1 所示的多协议标签交换（ Multi-protocol Label Switching, MPLS ) 网络，包括：运营商边缘 ( Provider Edge, PE ) 节点 PE1 和 PE2 , 以及运营商核心（ Provider, P )节点。虽然网络中的 PE节点能够识别业务类型和用户，但是网络中的 P 节点却不具有识别业务类型和用户的能力，因而 P节点在发生节点拥塞丟包时，也就不能有效获取丟包信息并告至信息中心供网络维护人员处理。 Network packet loss is a common network fault, including node congestion and packet loss, link delay jitter packet loss, etc., which will seriously affect the user experience. In the case of a node congestion packet loss, the node that has lost the packet knows that the packet loss has occurred, but the service type and user of the discarded packet are often not recognized, and there is no way to transmit the packet loss information. For example, the Multi-Protocol Label Switching (MPLS) network shown in Figure 1 includes: Carrier Edge (PE) nodes PE1 and PE2, and Carrier Core (Provider, P) nodes. Although the PE node in the network can identify the service type and the user, the P node in the network does not have the ability to identify the service type and the user. Therefore, when the node is congested and lost, the P node cannot effectively obtain the packet loss information. Report to the information center for network maintenance personnel to handle.

现有技术中，在网络出现严重丟包行为而影响到用户体验，以至用户产生抱怨并投诉至网络运营商后，网络维护人员进行分析处理。由于网络维护人员难以获取丟包信息，需要通过登录网络设备用命令行对逐个设备进行排查和解决；而对各个网络设备逐个进行排查，既耗时又容易遗漏。 In the prior art, network maintenance personnel perform analysis and processing after a serious packet loss behavior on the network affects the user experience, and the user complains and complains to the network operator. Because the network maintenance personnel can hardly obtain the packet loss information, you need to log in to the network device to check and solve the device one by one. The network devices are checked one by one, which is time-consuming and easy to miss.

具体实施方式 detailed description

本发明实施例提供一种网络丟包信息报告方法，用于在网络节点的接口发生队列拥塞丟包时，及时获取丟包信息，将丟包信息 4艮告到信息中心。队列拥塞丟包可以分为两种情况：一是设备故障导致的队列拥塞丟包；二是网络节点的某个接口处排队的报文较多，该接口不能及时将报文发送出去而导致的队列拥塞丟包。本发明实施例提供的方法适用于后一种情况，即，在网络节点的某个接口处排队的报文较多而导致队列拥塞丟包时，及时获取丟包信息，将丟包信息报告到信息中心。本发明实施例还提供相应的装置。以下结合附图对本发明实施例提供的方法和装置分别进行详细说明。 The embodiment of the present invention provides a network packet loss information reporting method, which is configured to timely obtain packet loss information and report the packet loss information to the information center when the network node's interface is congested and lost. Queue congestion packet loss can be divided into two cases: one is the queue congestion caused by device failure; the second is the network node. There are many packets queued at an interface. The interface cannot send packets out in a timely manner and the queue is congested and lost. The method provided by the embodiment of the present invention is applicable to the latter case, that is, when there are many packets queued at an interface of the network node, and the queue is congested and lost, the packet loss information is timely acquired, and the packet loss information is reported to information Center. Embodiments of the present invention also provide corresponding devices. The method and apparatus provided by the embodiments of the present invention are separately described in detail below with reference to the accompanying drawings.

请参考图 2, 本实施例提供一种网络丟包信息报告方法，包括： Referring to FIG. 2, this embodiment provides a network packet loss information reporting method, including:

101、处理节点获取丟包信息，所述丟包信息包括：丟包节点的地址、丟包节点的丟包接口信息、以及被丟弃报文的业务类型和用户信息。 The processing node obtains the packet loss information, where the packet loss information includes: an address of the packet loss node, a packet loss interface information of the packet loss node, and a service type and user information of the discarded packet.

所述的处理节点是指获取并处理丟包信息的节点设备，它可以是网络中具有识别业务类型和用户能力的节点，例如 MPLS网络中的 PE节点，或者网络电话 ( Voice over Internet Protocol , VoIP ) 网给中的媒体网关 ( media gateway, MGW )设备，等。 The processing node refers to a node device that acquires and processes packet loss information, and may be a node in the network that has an identified service type and user capability, such as a PE node in an MPLS network, or a voice over Internet Protocol (VoIP). Network media gateway (MGW) devices, etc.

所说的丟包节点是指发生丟包行为的节点设备，它可以是网络中的任意节点，既可以是具有识别业务类型和用户能力的节点，例如上述的 PE节点或媒体网关；也可以是不具有识别业务类型和用户能力的节点，例如 MPLS网络中的 P节点。丟包接口是指丟包节点上发生丟包行为的接口。 The packet loss node refers to a node device in which packet loss occurs, which may be any node in the network, and may be a node having an identification service type and user capability, such as the above-mentioned PE node or media gateway; There are no nodes that identify the type of service and user capabilities, such as P nodes in an MPLS network. A packet loss interface is an interface on which packet loss occurs on a packet loss node.

在丟包节点为具有识别业务类型和用户能力的节点时，处理节点和丟包节点可以是同一节点，称为丟包及处理节点，该丟包及处理节点可以直接获取自身的丟包信息。 When the packet loss node is a node with the identification of the service type and the user capability, the processing node and the packet loss node may be the same node, which is called a packet loss and processing node, and the packet loss and processing node may directly obtain the packet loss information of itself.

在丟包节点为不具有识别业务类型和用户能力的节点时，处理节点和丟包节点是不同的节点，此种情况下，处理节点获取丟包信息的步骤具体可以是： 101a, 处理节点接收丟包节点发送的丟包报告报文，所述丟包报告报文是丟包节点根据被丟弃报文生成的，携带有丟包节点的地址和丟包接口信息。 When the packet loss node is a node that does not have the service type and the user capability, the processing node and the packet loss node are different nodes. In this case, the step of the processing node acquiring the packet loss information may be: 101a, the processing node receives The packet loss report packet sent by the packet loss node is generated by the packet loss node according to the discarded packet, and carries the address of the packet loss node and the packet loss interface information.

丟包节点生成丟包报告报文的步骤具体可以是：丟包节点获取被丟弃报文，并获取自身的地址和丟包接口信息；丟包节点将所说的地址和接口信息写入所获取的被丟弃报文中，则写入了所述的地址和接口信息的被丟弃报文就成为了本文所说的丟包报告报文。 The packet loss node generates a packet loss report packet. The packet loss node obtains the discarded packet and obtains its own address and packet loss interface information. The packet loss node writes the address and interface information. In the obtained discarded packet, the discarded packet in which the address and interface information is written becomes the packet loss report packet mentioned in this document.

丟包节点发送丟包报告报文的步骤具体可以是：提高丟包报告报文的优先级，以丟包接口的最大发送能力将丟包报文发送给处理节点。其中，所说的丟包节点获取被丟弃报文包括：丟包节点统计单位时间内的丟包数量，根据该丟包数量判断丟包行为是常态化的偶尔丟包行为或者是突发性的丟包行为；如果是常态化的偶尔丟包行为，则获取每一个被丟弃的报文；如果是突发性的丟包行为，则按照预设比例获取被丟弃的报文，例如每丟弃 100 份报文获取一份被丟弃报文。 The packet loss node sends the packet loss report packet to the processing node. The packet loss report packet is sent to the processing node. The packet loss node obtains the discarded packet, including: the number of lost packets in the unit time of the packet loss node, and the packet loss behavior is normalized occasional packet loss behavior or suddenness according to the number of the packet loss. Packet loss behavior; if it is a normalized occasional packet loss behavior, it acquires each discarded packet; if it is a sudden packet loss behavior, it obtains the discarded packet according to a preset ratio, for example A discarded packet is obtained for every 100 packets discarded.

101b,处理节点提取丟包报告报文中携带的丟包节点的地址和丟包接口信息，并识别丟包报告报文的业务类型和用户信息。 101b. The processing node extracts the address of the packet loss node and the packet loss interface information carried in the packet loss report message, and identifies the service type and user information of the packet loss report message.

由于丟包报告报文是根据被丟弃报文生成的，因此，丟包报告报文的业务类型和用户信息也就是被丟弃文的业务类型和用户信息。 The packet loss report packet is generated based on the discarded packet. Therefore, the service type and user information of the packet loss report packet are the service type and user information of the discarded packet.

所说的接口信息至少包括接口索引，还可以包括接口描述等信息。 The interface information includes at least an interface index, and may also include information such as an interface description.

所说的业务类型可以是个人上网业务（High Speed lnternet , HSI ), 交互式网络电视（IPTV )业务，网络电话（VoIP )业务，或企业虚拟专用网络（Virtual Private Network, VPN ) 业务等。不同类型的报文携带的标签是不同的，可以通过识别标签来区分业务类型，例如 MPLS网络中 PE节点为不同的业务创建不同的虚拟专用网络（ Virtual Private Network, VPN ) , 可以通过识别报文的 VPN 标签来区分业务类型。 The type of service may be a personal high-speed Internet (HSI), an interactive network television (IPTV) service, a VoIP service, or a virtual private network (VPN) service. Different types of packets carry different labels. You can identify the service type by identifying the label. For example, the PE node in the MPLS network creates different virtual private networks (VPNs) for different services. VPN tags to differentiate business types.

所说的用户信息可以是地址信息或者电话号码等。报文中携带有发送方和接收方的网络（ IP )地址，可以用 IP地址表示用户。在某些类型的网络例如 VoIP 网络中，报文中也会携带用户的电话号码等信息，此时也可以用电话号码表示用户。 The user information may be address information or a telephone number or the like. The message carries the network (IP) address of the sender and the receiver, and the user can be represented by the IP address. In some types of networks, such as VoIP networks, messages also carry information such as the user's phone number. In this case, the user can also be represented by a phone number.

至此，处理节点已经获取了足够的丟包信息，丟包信息至少包括：丟包节点的地址、丟包节点中丟包接口信息、以及被丟弃报文的业务类型和用户信息。当然，在具体的应用中，处理节点也可以获取更多的丟包信息,例如，丟包接口处的队列深度等信息。 At this point, the processing node has obtained sufficient packet loss information. The packet loss information includes at least: the address of the packet loss node, the packet loss interface information in the packet loss node, and the service type and user information of the discarded packet. Of course, in a specific application, the processing node can also obtain more packet loss information, for example, the queue depth at the packet loss interface.

下面以 MPLS网络为例进行说明： The following takes the MPLS network as an example:

在 MPLS网络中，由于 PE节点（一般为网关设备）具有识别业务类型和用户能力，因此可以以 PE节点作为处理节点。如果丟包节点是 PE节点，则 PE节点可以直接获取丟包信息；如果丟包节点是 P节点，则 P节点可以获取被丟弃报文，根据获取的被丟弃报文生成携带有丟包节点的地址和丟包接口信息的丟包报告报文，并将丟包报告报文发送给 PE节点， PE节点可以从接收到的 P节点发送的丟包报告报文中提取丟包信息。 In an MPLS network, since a PE node (generally a gateway device) has an identification service type and a user capability, a PE node can be used as a processing node. If the packet loss node is a PE node, the PE node can directly obtain the packet loss information. If the packet loss node is a P node, the P node can obtain the discarded packet and generate a packet loss packet according to the obtained discarded packet. Packet loss of node address and packet loss interface information Reporting the packet, and sending the packet loss report message to the PE node, the PE node can extract the packet loss information from the received packet loss report message sent by the P node.

下面，以 P节点为例，对丟包节点生成丟包报告报文的过程进行描述：假设 P节点的一个接口发生了队列拥塞丟包，某用户的报文在队列已满的情况下不断被丟弃。由于 P节点在实时监测自身的丟包行为，因而 P节点知道该接口发生了丟包，但是不知道被丟弃报文的业务类型和用户信息。此时， P节点可以按预定比例选取被丟弃的报文，例如，每丟弃 100份报文，选取一份报文。然后， P节点将自身的地址以及丟包接口信息一并写入所选取报文的数据区。从而，所选取的被丟弃报文转换成为丟包报告报文。最后， P节点将该丟包报告报文发送给 PE节点。通过定义选取报文的比例，可以决定发送丟包报告才艮文的频次。 The following takes the P node as an example to describe the process of generating a packet loss report packet on the packet loss node: Assume that a packet on the P node has a queue congestion packet loss, and a packet of a user is continuously received when the queue is full. throw away. Because the P node monitors its own packet loss behavior in real time, the P node knows that the interface has lost packets, but does not know the service type and user information of the discarded packets. At this time, the P node can select the discarded packet according to a predetermined ratio. For example, for every 100 packets discarded, a packet is selected. Then, the P node writes its own address and the packet loss interface information together into the data area of the selected packet. Therefore, the selected discarded packet is converted into a packet loss report message. Finally, the P node sends the packet loss report message to the PE node. By defining the proportion of the selected message, you can decide how often the packet loss report will be sent.

102、处理节点将所述丟包信息发送给信息中心。 102. The processing node sends the packet loss information to the information center.

信息中心用于接收各个处理节点发送的丟包信息。也就是说，网络中的所有丟包信息均在信息中心集中，供网络维护人员分析处理使用。在不同的网络中，所说的信息中心可以是不同的设备。在 MPLS网络中，与作为处理节点的 PE节点连接的网络流量（Netstream )服务器可以作为信息中心；在 VoIP网络中，与媒体网关连接的软交换设备 ( Softswitch )可以作为信息中心。 The information center is used to receive packet loss information sent by each processing node. That is to say, all packet loss information in the network is centralized in the information center for network maintenance personnel to analyze and use. In different networks, the information center can be different devices. In an MPLS network, a network traffic (Netstream) server connected to a PE node as a processing node can serve as an information center; in a VoIP network, a softswitch device (Softswitch) connected to a media gateway can serve as an information center.

处理节点可以将丟包信息直接发送给信息中心；也可以将丟包信息发送给下游设备，由该下游设备将丟包信息发送给信息中心。当然，由于处理节点连接的信息中心和下游设备连接的信息中心可能是不同的设备，为了使各个信息中心设备均能收集到丟包信息，处理节点可以将丟包信息既发送给信息中心，又发送给下游设备。 The processing node can send the packet loss information to the information center directly. The packet loss information can be sent to the downstream device. The downstream device sends the packet loss information to the information center. Of course, since the information center connected to the processing node and the information center connected to the downstream device may be different devices, in order to enable the information center device to collect the packet loss information, the processing node may send the packet loss information to the information center, and Send to downstream devices.

例如，在处理节点是 MPLS域内的 PE节点时，处理节点将丟包信息发送给信息中心可以包括： For example, when the processing node is a PE node in the MPLS domain, the processing node sends the packet loss information to the information center, which may include:

PE节点将丟包信息发送给 Netstream服务器；或者， The PE node sends the packet loss information to the NetStream server; or

PE节点将丟包信息发送位于 MPLS域外的下游设备，再由下游设备将丟包信息发送给该下游设备连接的信息中心；例如，下游设备是媒体网关时，媒体网关设备在收到丟包信息后，可以将丟包信息发送软交换设备。 The PE node sends the packet loss information to the downstream device outside the MPLS domain, and then the downstream device sends the packet loss information to the information center connected to the downstream device. For example, when the downstream device is the media gateway, the media gateway device receives the packet loss information. After that, the packet loss information can be sent to the softswitch device.

其中， PE节点将丟包信息发送给 Netstream服务器具体可以是： PE节点将丟包信息封装在网络协议（Internet Protocol, IP )数据流信息输出（IP Flow Information Export, IPFIX ) 文中发送给 Netstream服务器。 The PE node sends the packet loss information to the NetStream server. The PE node will: The packet loss information is encapsulated in the Internet Protocol (IP) Data Flow Information Export (IPFIX) text and sent to the NetStream server.

PE节点将丟包信息发送位于 MPLS域外的下游设备具体可以是：将丟包信息封装在因特网控制报文协议（Internet Control Message Protocol, ICMP )报文中发送给作为下游设备的媒体网设备关，由媒体网关设备将丟包信息封装在会话初始协议（ Session Initiation Protocol, SIP )信令才艮文中发送给软交换设备。 The PE node sends the packet loss information to the downstream device that is located outside the MPLS domain. The packet loss information is encapsulated in the Internet Control Message Protocol (ICMP) packet and sent to the media network device as the downstream device. The packet loss information is encapsulated in the Session Initiation Protocol (SIP) signaling message sent by the media gateway device to the softswitch device.

IPFIX是基于流的技术，具有广泛的应用，具体包括华为的 NetStream技术、思科（Cisco ) 的 NetFlow技术等。版本九（ Version9 ) 的 NetStream是基于模板（ Template ) 的，模板提供了灵活可扩展的报文输出格式，这使得在不改变基本记录格式的情况下，方便的增加了新的流统计服务。 NetStream Version9的格式不固定，其中一种格式表 1所示，包括：包头（ Packet Header )、模板流量集（Template flowset ) 以及与模板流量集对应的数据流量集（Date flowset )等域。本实施例中，可以定义一个描述丟包信息的模板流量集，将丟包信息写入模板对应的数据流量集中，实现将丟包信息封装在 IPFIX报文中。 IPFIX is a stream-based technology with a wide range of applications, including Huawei's NetStream technology and Cisco's NetFlow technology. Version 9 (Version9) NetStream is based on Template. The template provides a flexible and extensible message output format, which makes it easy to add new stream statistics services without changing the basic record format. The format of NetStream Version 9 is not fixed. One of the format tables 1 includes: a packet header, a template flowset, and a data flow set corresponding to the template traffic set. In this embodiment, a template traffic set that describes the packet loss information may be defined, and the packet loss information is written into the data traffic set corresponding to the template, so that the packet loss information is encapsulated in the IPFIX packet.

表 1

Table 1

ICMP是一种面向连接的协议，用于传输出错报告控制信息。 ICMP报文的格式如表 2所示，包括： IP头部、类型、代码、校验和、标识符、序列号、有效载荷等域。本实施例中，可以利用现有网络中不采用的类型字段，或者通过扩充类型字段增加丟包报告报文类型，将 ICMP报文标识为丟包报告报文，然后将丟包信息写入有效载荷（PayLoad ) 。 ICMP is a connection-oriented protocol for transmitting error reporting control information. The format of the ICMP message is shown in Table 2. It includes: IP header, type, code, checksum, identifier, serial number, payload, and so on. In this embodiment, the type field that is not used in the existing network may be used, or the packet type of the packet loss report may be increased by using the extended type field, and the ICMP packet is identified as a packet loss report packet, and then the packet loss information is effectively written. Load (PayLoad).

SIP是一个会话层的信令控制协议。 SIP信令报文的格式如表 3所示，包括: SIP版本（ version )、状态代码（ Status code )、与状态代码对应的原因字段（ Reason phrase )等域。本实施例中，可以通过扩展状态代码增加丟包报告报文类型，将 SIP信令报文标识为丟包报告报文，然后将丟包信息写入增加的状态代码对应的原因字段中。 SIP is a session layer signaling control protocol. The format of the SIP signaling packet is shown in Table 3. It includes: The SIP version ( version ), status code (Status code), and the reason field corresponding to the status code ( Reason phrase ). In this embodiment, the packet loss report type is increased by the extended status code, the SIP signaling packet is identified as a packet loss report message, and the packet loss information is written in the reason field corresponding to the added status code.

表 3 table 3

SIP version Status code Reason phrase 信息中心收到的丟包信息至少包括：丟包节点的地址、丟包节点的丟包接口信息、以及被丟弃报文的业务类型和用户信息。信息中心收到丟包信息后，就可以利用所述丟包节点的地址信息定位异常设备（即丟包节点）在网络中的位置，利用所述接口信息定位异常端口（即丟包节点的丟包接口）在异常设备上的位置，利用所述业务类型和用户信息对该业务和用户的月良务质量（ Quality of Service, QoS )参数进行调整或通过增加物理链路调整带宽，改善网络服务质量。 The packet loss information received by the information center includes at least the address of the packet loss node, the packet loss interface information of the packet loss node, and the service type and user information of the discarded packet. After receiving the packet loss information, the information center can use the address information of the packet loss node to locate the location of the abnormal device (that is, the packet loss node) in the network, and use the interface information to locate the abnormal port (that is, the lost node). The location of the packet interface on the abnormal device, using the service type and user information to adjust the Quality of Service (QoS) parameters of the service and the user, or adjusting the bandwidth by adding a physical link, and improving the network service. quality.

需要说明的是，丟包节点按照预设比例获取被丟弃的报文时，有些类型的被丟弃报文会被漏选，则有可能发生丟包信息丟失的情况，针对这种情况，信息中心收到丟包信息后，可以认为该丟包节点的该丟包接口的与所述被丟弃报文的优先级相同的所有种类的报文都存在丟包现象。 It should be noted that when a packet loss node obtains a discarded packet according to a preset ratio, some types of discarded packets are missed, and packet loss information may be lost. After receiving the packet loss information, the information center can be considered to have packet loss on all types of packets of the packet loss interface that have the same priority as the discarded packet.

采用本发明实施例方法，网络节点在发生队列拥塞丟包时，丟包节点可以通过处理节点将丟包信息集中传递到信息中心。这样，网络维护人员就可以从信息中心知悉各个节点的丟包信息，方便的进行分析解决，而不必通过登录网络设备用命令行对逐个设备进行排查和解决。从而，可以提升网络业务丟包问题定位及处理速度，能够有效降低网络运行维护费用。 According to the method of the embodiment of the present invention, when a network node loses packet loss, the packet loss node can centrally transmit the packet loss information to the information center through the processing node. In this way, the network maintenance personnel can know the packet loss information of each node from the information center, and conveniently analyze and solve the problem without having to log in to the network device to check and solve each device by command line. Therefore, the positioning and processing speed of the network service packet loss problem can be improved, and the network operation and maintenance cost can be effectively reduced.

一种实施方式中，为了使处理节点易于将接收的丟包报告报文与普通的报文区分开来，丟包节点在生成丟包报告报文的过程中，可以在选取的被丟弃报文中写入预先定义好的检测标签（Diagnostic Label ), 以表示包含该检测标签的报文为丟包报告报文。本实施例中，上述步骤 101a具体可以包括： In an implementation manner, in order to make the processing node easy to distinguish the received packet loss report message from the ordinary message, the packet loss node may select the discarded report in the process of generating the packet loss report message. A predefined detection label (Diagnostic Label) is written in the text to indicate that the packet containing the detection label is a packet loss report message. In this embodiment, the foregoing step 101a may specifically include:

101al、处理节点接收发生丟包节点发送的报文； The processing node receives the packet sent by the packet loss node.

101a2、检测接收的报文是否包含检测标签； 101a2, detecting whether the received packet includes a detection label;

101a3、确认包含检测标签的报文为丟包报告报文。本实施例中，以检测标签来标识丟包报告报文，使处理节点能够方便快捷的从接收到的大量报文中识别出丟包报告报文，加快处理速度。 101a3. Confirm that the packet containing the detection label is a packet loss report message. In this embodiment, the detection packet is used to identify the packet loss report packet, so that the processing node can quickly and easily identify the packet loss report packet from the received large number of packets, thereby speeding up the processing.

请参考图 3, 本实施例提供一种网络丟包信息报告方法，包括： Referring to FIG. 3, this embodiment provides a network packet loss information reporting method, including:

201、丟包节点获取被丟弃报文，根据获取的被丟弃报文生成丟包报告报文，所述丟包报告报文携带丟包节点的地址和丟包接口信息。 201. The packet loss node obtains the discarded packet, and generates a packet loss report packet according to the obtained discarded packet, where the packet loss report packet carries the address of the packet loss node and the packet loss interface information.

具体的，丟包节点获取被丟弃报文，并获取自身的地址以及具体发生队列拥塞丟包的丟包接口信息；丟包节点将所说的地址和接口信息写入所获取的被丟弃报文中，则写入了所述地址和接口信息的被丟弃报文就成为了本文所说的丟包报告报文。 Specifically, the packet loss node obtains the discarded packet, and obtains its own address and the packet loss interface information of the specific congestion packet loss; the packet loss node writes the address and interface information and the obtained packet is discarded. In the message, the discarded packet with the address and interface information written becomes the packet loss report message.

其中，所说的丟包节点获取被丟弃报文包括：丟包节点统计单位时间内的丟包数量，根据该丟包数量判断丟包行为是常态化的偶尔丟包行为或者是突发性的丟包行为；如果是常态化的偶尔丟包行为，则获取每一个被丟弃的报文；如果是突发性的丟包行为，则按照预设比例获取被丟弃的报文，例如每丟弃 100 份报文获取一份被丟弃报文。 The packet loss node obtains the discarded packet, including: the number of lost packets in the unit time of the packet loss node, and the packet loss behavior is normalized occasional packet loss behavior or suddenness according to the number of the packet loss. Packet loss behavior; if it is a normalized occasional packet loss behavior, it acquires each discarded packet; if it is a sudden packet loss behavior, it obtains the discarded packet according to a preset ratio, for example A discarded packet is obtained for every 100 packets discarded.

下面以丟包节点为 MPLS网络中的 P节点为例进行说明： The following takes the packet loss node as the P node in the MPLS network as an example:

假设 P节点的一个接口发生了队列拥塞丟包，某用户的报文在队列已满的情况下不断被丟弃。由于 P节点在实时监测自身的丟包行为，因而 P节点知道该接口发生了丟包，但是不知道被丟弃报文的类型和用户信息。此时， P节点可以按预定比例选取被丟弃的报文，例如，每丟弃 100份报文，选取一份报文。然后， P节点将自身的地址以及丟包接口信息一并写入所选取报文的数据区。从而，所选取的被丟弃报文转换成为丟包报告报文。 Assume that a packet on the P-node is congested and packet loss occurs. A packet of a user is continuously discarded when the queue is full. Because the P node monitors its own packet loss behavior in real time, the P node knows that the interface has lost packets, but does not know the type of discarded packets and user information. At this time, the P node can select the discarded packet according to a predetermined ratio. For example, each time 100 packets are discarded, one packet is selected. Then, the P node writes its own address and the packet loss interface information together into the data area of the selected message. Therefore, the selected discarded packet is converted into a packet loss report message.

202、丟包节点将丟包报告报文发送给处理节点，以便处理节点从丟包报告报文获取丟包信息，并将丟包信息发送给信息中心，该丟包信息包括：丟包节点的地址、丟包节点的丟包接口信息、以及被丟弃报文的业务类型和用户信息。 202. The packet loss node sends the packet loss report message to the processing node, so that the processing node obtains the packet loss information from the packet loss report message, and sends the packet loss information to the information center, where the packet loss information includes: Address, packet loss interface information of the packet loss node, and service type and user information of the discarded packet.

本步骤中，不具有识别业务类型和用户能力的丟包节点，将生成的丟包报告报文中继到具有识别业务类型和用户能力的处理节点（例如 PE节点），通过处理节点将丟包信息发送到信息中心。 In this step, the packet loss node that does not have the service type and the user capability is configured to relay the generated packet loss report message to a processing node (such as a PE node) that has the identified service type and user capability, and the packet is lost through the processing node. Information is sent to the information center.

其中，丟包节点发送丟包报告报文的步骤具体可以是：提高丟包报告报文的优先级，以丟包接口的最大发送能力将丟包报告报文发送给处理节点。 The step of sending a packet loss report packet by the packet loss node may be: improving the packet loss report packet. The priority of the packet is sent to the processing node by the maximum transmission capability of the packet loss interface.

采用本发明实施例方法，网络中节点在发生队列拥塞丟包时，可以通过处理节点将丟包信息集中传递到信息中心。这样，网络维护人员就可以从信息中心知悉各个节点的丟包信息，方便的进行分析解决，而不必通过登录网络设备用命令行对逐个设备进行排查和解决。从而，可以提升网络业务丟包问题定位及处理速度，能够有效降低网络运行维护费用。 According to the method of the embodiment of the present invention, when a node in the network loses a packet, the processing node can centrally transmit the packet loss information to the information center. In this way, the network maintenance personnel can know the packet loss information of each node from the information center, and conveniently analyze and solve the problem without having to log in to the network device to check and solve each device by command line. Therefore, the positioning and processing speed of the network service packet loss problem can be improved, and the network operation and maintenance cost can be effectively reduced.

一种实施方式中，为了使处理节点易于将接收的丟包报告报文与普通的报文区分开来，丟包节点在生成丟包报告报文的过程中，可以在选取的报文中写入预先定义好的检测标签，以表示包含该检测标签的报文为丟包报告报文。本实施例中，上述步骤 201具体可以包括： In an implementation manner, in order to make the processing node easy to distinguish the received packet loss report message from the ordinary message, the packet loss node may write in the selected message in the process of generating the packet loss report message. Enter a predefined detection label to indicate that the packet containing the detection label is a packet loss report message. In this embodiment, the foregoing step 201 may specifically include:

丟包节点获取被丟弃报文，并获取自身的地址以及丟包接口信息；丟包节点将所说的地址和接口信息以及预定义的检测标签写入所获取的被丟弃报文中，以生产丟包报告报文。 The packet loss node obtains the discarded packet and obtains its own address and the packet loss interface information. The packet loss node writes the address and interface information and the predefined detection label into the obtained discarded packet. To produce a packet loss report message.

经过本步骤，写入了上述各项信息的被丟弃报文就成为了本文所说的丟包报告报文；其中，检测标签用于表示包含该检测标签的报文为丟包报告报文。 After this step, the discarded packet that has been written with the above information becomes the packet loss report packet. The detection label is used to indicate that the packet containing the detection label is a packet loss report packet. .

本实施例中，以检测标签来标识丟包报告报文，使处理节点能够方便快捷的从接收到的大量报文中识别出丟包报告报文，加快处理速度。 In this embodiment, the detection packet is used to identify the packet loss report packet, so that the processing node can quickly and easily identify the packet loss report packet from the received large number of packets, thereby speeding up the processing.

请参考图 4所示的 MPLS网络，在图 2和图 3提供的上述实施例的基础上，本实施例提供的网络丟包信息报告方法应用于 MPLS网络域内。该 MPLS网络包括节点 PE1、 P和 PE2, PE1和 PE2均与 Netstream服务器连接。其中，处理节点可以是节点 PE1或 PE2。 Referring to the MPLS network shown in FIG. 4, based on the foregoing embodiment provided in FIG. 2 and FIG. 3, the network packet loss information reporting method provided in this embodiment is applied to the MPLS network domain. The MPLS network includes nodes PE1, P, and PE2, and both PE1 and PE2 are connected to the Netstream server. The processing node can be node PE1 or PE2.

本实施例中，某种报文从节点 PE1进入 MPLS网络，该报文包含两层标签，其第一层标签为传输标签（Tunnel Label ), 第二层标签为用户标签；其中用户标签具体可以是业务标签或者虚拟信道标签（ Virtual Channel Label, VC Label ) 或者虚拟专用网标签（ Virtual Private Network Label, VPN Label )。假定用户标签为 2 ,传输标签为 18。假设该种报文在 Ρ节点的某个接口发生队列拥塞丟包，贝' JP节点按预定比例选取被丟弃报文，压入检测标签（例如 15 )。此时，由于该报文已到达 Ρ节点，传输标签已经交换，假设此时的传输标签为 4。压入检测标签后，三层标签具体为：第一层传输标签 4, 第二层检测标签 15, 第三层用户标签 2。即，检测标签代替用户标签被压入第二层，而用户标签改为压入第三层。同时， P节点获取自身的地址和丟包接口的接口信息，将该地址和接口信息写入被丟弃报文的数据区。至此，被丟弃报文转换成为丟包报告报文。然后将该丟包报告报文发送给处理节点 PE2进行处理。图 5示出了处理节点 PE2对收到丟包报告报文后的处理过程，包括： In this embodiment, a certain packet enters the MPLS network from the node PE1, and the packet includes two layers of labels. The first layer label is a tunnel label, and the second layer label is a user label. It is a service label or a virtual channel label (VC Label) or a virtual private network label (VPN Label). Assume that the user tag is 2 and the transport tag is 18. Assume that the packet has a queue congestion packet on an interface of the node, and the PM' JP node selects the discarded packet according to a predetermined ratio and pushes the detection label (for example, 15). At this time, since the message has arrived at the node, the transport label has been exchanged, assuming that the transport label at this time is 4. After the detection label is pressed, the three-layer label is specifically: the first layer transmission label 4, the second layer detection label 15, the third layer user Label 2. That is, the detection tag is pressed into the second layer instead of the user tag, and the user tag is pressed into the third layer instead. At the same time, the P node obtains its own address and interface information of the packet loss interface, and writes the address and interface information into the data area of the discarded packet. At this point, the discarded message is converted into a packet loss report message. The packet loss report message is then sent to the processing node PE2 for processing. FIG. 5 shows a process after the processing node PE2 receives the packet loss report message, including:

401、 PE2接收报文并检测收到的报文是否包含检测标签。 401. The PE2 receives the packet and detects whether the received packet includes the detection label.

具体的， PE2收到报文后，弹出第二层标签，如果该报文为丟包报告报文，则弹出的第二层标签是检测标签，从而 PE2根据预先设置确认该报文为丟包报告报文，然后对该丟包报告报文进行后续处理。如果弹出的第二层标签是用户标签，说明仅仅是普通的报文，则 PE2照常执行转发操作。 Specifically, after the packet is received by the PE2, the second layer label is displayed. If the packet is a packet loss report packet, the second layer label is a detection label. Therefore, the PE2 confirms that the packet is a packet according to a preset setting. Report the packet, and then perform subsequent processing on the packet loss report packet. If the second layer label is a user label, the description is only a normal packet, and PE2 performs the forwarding operation as usual.

402、 PE2获取丟包报告报文携带的丟包信息。 402. The PE2 obtains the packet loss information carried in the packet loss report packet.

具体包括： PE2提取丟包报告报文携带的丟包节点的地址和丟包接口的接口信息，识别丟包报告报文的业务类型和用户信息。 Specifically, the PE2 extracts the address of the packet loss node and the interface information of the packet loss interface, and identifies the service type and user information of the packet loss report message.

403、 PE2将丟包信息发送给信息中心，所述丟包信息包括：丟包节点的地址、丟包节点的丟包接口的接口信息、以及被丟弃报文的业务类型和用户信息。 403. The PE2 sends the packet loss information to the information center, where the packet loss information includes: an address of the packet loss node, an interface information of the packet loss interface of the packet loss node, and a service type and user information of the discarded packet.

具体可以是： PE2将丟包信息封装在 IPFIX报文中，发送给 Netstream服务器；或者， PE2将丟包信息封装在 ICMP报文中，根据用户信息中的的接收方地址将该 ICMP报文发送给下游设备，再由下游设备将丟包信息发送给该下游设备连接的信息中心；例如，下游设备是媒体网关时，媒体网关在收到丟包信息后，可以将丟包信息发送软交换设备。其中，可以在 PE2的访问控制列表（ Access Control List, ACL ) 中进行配置，指定是否要将丟包信息发送给下游设备。 Specifically, the PE2 encapsulates the packet loss information in the IPFIX packet and sends the packet to the NetStream server. Alternatively, the PE2 encapsulates the packet loss information in the ICMP packet, and sends the ICMP packet according to the receiver address in the user information. The downstream device sends the packet loss information to the information center connected to the downstream device. For example, when the downstream device is the media gateway, the media gateway can send the packet loss information to the softswitch device after receiving the packet loss information. . It can be configured in the Access Control List (ACL) of PE2 to specify whether to send packet loss information to downstream devices.

本实施例中，对于如何使用检测标签来标识丟包报告报文进行了详细说明，通过该种方式，处理节点可以快速从接收到的大量报文中识别出丟包报告报文，从而及时提取并发送丟包信息到信息中心。 In this embodiment, how to use the detection label to identify the packet loss report message is described in detail. In this manner, the processing node can quickly identify the packet loss report message from the received large number of packets, so as to timely extract And send the packet loss information to the information center.
