Description

Packet loss statistics realization method and device for message

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for implementing packet loss statistics for a packet.

Background

In the internet era, more and more services are transmitted through IP networks and each service becomes extremely sensitive to the loss of data packets. Such as voice and video traffic. In order to accurately determine whether data packet loss occurs in the IP Network and at which position the data packet loss occurs, y.1731 technology and Network Quality Analysis (NQA) technology should be applied.

Both the y.1731 and NQA techniques are indirect measurement techniques, which first construct a plurality of statistical messages to form an emulation stream or an insertion stream. And the performance statistical data of the service message is indirectly obtained through the statistics of the statistical message.

However, the two techniques described above also have the following problems in practical use: 1) the Y.1731 technology is suitable for a two-layer Ethernet network, and can not realize the performance statistics of service messages crossing a three-layer network; 2) because the Y.1731 technology and the NQA technology are indirect measurement technologies, the overhead of network equipment is increased, and the passing condition of real service flow in the network and the network equipment cannot be directly reflected; 3) neither the y.1731 technique nor the NQA technique supports multipoint-to-multipoint networking, and cannot meet the performance statistical requirements of service messages in the presence of multiple paths in an IP network.

The packet loss statistics implementation method for the packet provided in the embodiment of the present application is described in detail below. Referring to fig. 1, fig. 1 is a flowchart of a packet loss statistics implementation method for a packet according to an embodiment of the present application. The method is applied to network equipment, and the packet loss statistics implementation method of the packet provided by the embodiment of the application can comprise the following steps.

Step 110, receiving a first data request sent by the network management system, where the first data request is used for the network management system to obtain instance data configured in the network device, and the instance data includes a configured instance list, a collector list configured under each instance in the instance list, and an atomic measurement section AMS list.

Specifically, the network management device needs to obtain instance data configured in the network device, so as to reconstruct and display a transmission path for forwarding the service packet through the obtained instance data.

The network management system generates a first data request, and the first data request is used for the network management system to obtain instance data configured in the network equipment. The instance data includes a configured instance list, a Collector (Collector) list configured under each instance in the instance list, and an Atomic Measurement Span (AMS) list.

The collector is responsible for managing and controlling a Measurement Point (MP), collecting statistical data about service packets collected by the MP, and reporting the statistical data to an Analyzer (Analyzer). The analyzer is responsible for collecting the statistical data of the related service messages reported by the collector and finishing the summarization and calculation of the data. The MP is responsible for measuring actions of processing the service packet and generating measurement data, and for a specific target service flow, the MP includes three roles of an ingress measurement point (in-point), an egress measurement point (out-point), and an intermediate measurement point (mid-point). That is, the service message is dyed at the entrance measuring point, and the service message is undyed at the exit measuring point, so that the service message is counted. And the AMS is associated with the MP, and the packet loss data of each hop of the service message is counted.

In the embodiment of the present application, the Network device and the Network management system are communicatively connected through respective Network Configuration Protocol (Network Configuration Protocol, abbreviated as Netconf) interfaces.

The network management system sends a first data request to the network equipment.

And step 120, acquiring a configured instance list, a Collector (Collector) list configured under each instance, and an Atomic Measurement range (AMS) list according to the first data request.

Specifically, after receiving the first data request, the network device determines, according to the first data request, that the network management system needs to obtain an instance list configured by the network device, a collector list configured under each instance in the instance list, and an AMS list.

In the embodiment of the present application, the configured instance list, collector list, and AMS list of the network device are as follows:

in the foregoing example, the network device includes an instance, identified as instance 1.

This example 1 is followed by a collector list. The collector list includes four collectors, each identified by its IP address.

For example, collector identification of collector 1 is 1.1.1.1, collector identification of collector 2 is 1.1.1.3, collector identification of collector 3 is 1.1.1.5, and collector identification of collector 4 is 1.1.1.7.

The AMS list is also configured under this example 1. The AMS list includes seven AMSs and is distinguished by AMS identification. For example AMS1, AMS2, AMS3, AMS4, AMS5, AMS6, AMS 7.

Each AMS includes an identifier of an MP in an MP group (inggroup), an identifier of a collector associated with the MP, an identifier of an MP in an MP out group (OutGroup), and an identifier of a collector associated with the MP.

For example, the identifier of an MP under an MP group entered by AMS1 is MP1, the identifier of a collector associated with MP1 is 1.1.1.1, the identifier of an MP under an MP group exited by AMS1 is MP2, and the identifier of a collector associated with MP2 is 1.1.1.1. The identification of the MP under the MP group entered by the AMS2 is MP2, the collector identification associated with the MP2 is 1.1.1.1, the identification of the MP under the MP group exited by the AMS2 is MP1, and the collector identification associated with the MP1 is 1.1.1.3. Similarly, AMS3-AMS7 include the same configuration structures and are not repeated here.

Step 130, sending a first data response to the network management system, where the first data response includes the instance list, the collector list configured under each instance, and the atomic measurement section AMS list, so that the network management system reconstructs and displays a transmission path of a service packet according to the instance list, the collector list configured under each instance, and the atomic measurement section AMS list.

Specifically, the network device generates a first data response after acquiring the configured instance list, the collector list configured under each instance, and the atomic measurement section AMS list. The first data response includes a list of instances, a list of collectors configured under each instance, and a list of atomic measurement segment AMSs.

The network device sends a first data response to the network management system.

And after receiving the first data response, the network management system acquires the configured instance list of the network equipment, the configured collector list under each instance and the atomic measurement section AMS list. And according to the example list, the collector list configured under each example and the atomic measurement section AMS list, reconstructing and displaying the transmission path of the service message by the network management system.

Further, from the AMS list, the network management system sequentially obtains the recorded AMS identifications of each AMS, collector identifications associated with MPs in the MP group of each AMS, and collector identifications associated with MPs in the MP group of each AMS. From the collector list, the network management device sequentially obtains the collector identifier of each collector of the record. And according to the collector identifier of each collector, the collector identifier associated with the MP under the MP group of each AMS and the collector identifier associated with the MP under the MP group of each AMS, the network management system determines the MP associated with each collector and the interface of the network equipment serving as the collector associated with the MP. According to the interface of the network equipment which is related to the MP and is used as the collector, the network management equipment determines the link connection relation between the collectors. And according to the link connection relation between the collectors, the network management equipment reconstructs and displays the transmission path of the service message.

According to the foregoing example, the network management device sequentially acquires AMS1, AMS2, AMS3, AMS4, AMS5, AMS6, AMS7, a collector identifier (e.g., 1.1.1.1) of an MP association under an in-MP group of each AMS, and a collector identifier (e.g., 1.1.1.1) of an MP association under an out-MP group of each AMS. According to the collector identification of each collector, the collector identification associated with the MP under the MP group of each AMS and the collector identification associated with the MP under the MP group of each AMS, the network management system determines the MP (such as MP1) associated with each collector and the interface of the network equipment which is associated with the MP and is used as the collector. According to the interface of the network equipment which is related to the MP and is used as the collector, the network management equipment determines the link connection relation between the collectors. According to the link connection relationship between the collectors, the network management device reconstructs and displays the transmission path of the service message, as shown in fig. 2. Fig. 2 is a schematic transmission path diagram of a reconstructed service packet according to an embodiment of the present application.

In fig. 2, four collectors recorded in the collector list are sequentially connected.

Step 140, receiving a second data request sent by the network management system, where the second data request is used for the network management system to obtain packet loss data of each instance in the current period and packet loss data of each AMS in the AMS list configured in each instance.

Specifically, after reconstructing and displaying the transmission path of the service packet, the network management device needs to obtain packet loss data of each instance of the network device in the current period and packet loss data of each AMS in the AMS list configured in each instance.

Further, the network management system creates a periodic task, that is, the network management system obtains packet loss data of each instance in the network device and packet loss data of each AMS in the AMS list configured under each instance in a certain period (for example, 3 hours).

And the network management system generates a second data request, wherein the second data request is used for the network management system to acquire the packet loss data of each instance in the current period and the packet loss data of each AMS in the AMS list configured under each instance. The second data request includes periodic information.

And the network management system sends a second data request to the network equipment.

Step 150, obtaining the packet loss data of each instance and the packet loss data of each AMS according to the second data request.

Specifically, after receiving the second data request, the network device obtains packet loss data of each instance and packet loss data of each AMS in the period according to the second data request.

In the embodiment of the present application, the network device obtains packet loss data of each instance and packet loss data of each AMS in the period as follows:

in the foregoing example, the number of packet loss data of example 1 is 249387; the number of lost packet data of the AMS1 is 498774; the number of lost packets of the AMS2 is 498554.

Step 160, sending a second data response to the network management system, where the second data response includes the packet loss data of each instance and the packet loss data of each AMS, so that the network management system displays the packet loss data of each instance and the packet loss data of each AMS in a transmission path of the service packet.

Specifically, the network device generates a second data response after acquiring the packet loss data of each instance and the packet loss data of each AMS in the period. The second data response includes packet loss data of each instance and packet loss data of each AMS at the period.

And the network equipment sends a second data response to the network management system.

And after receiving the second data response, the network management system acquires the packet loss data of each instance and the packet loss data of each AMS in the period. And the network management system displays the packet loss data of each example and the packet loss data of each AMS in a transmission path of the service message.

Further, according to the collector identifier associated with the MP under the MP group of each AMS and the collector identifier associated with the MP under the MP group of each AMS, the network management system determines whether the collector identifiers associated with the MP under the MP group and the MP under the MP group are the same collector. If so, the network management system displays the packet loss data of the AMS below the collector represented by the collector identifier; and if not, the network management system displays the packet loss data of the AMS above the link correspondingly formed by the plurality of collector identifications.

According to the foregoing example, in one example, the collector identification of an MP association under an in-MP group of AMS1 is 1.1.1.1; if the collector identifier of the MP association under the outgoing MP group of the AMS1 is 1.1.1.1, the network management system determines that the collector identifier of the MP association under the incoming/outgoing MP group of the AMS1 is the same collector, and the network management system displays the packet loss data of the AMS1 below the collector represented by the collector identifier 1.1.1.1.

In another example, the collector identification of an MP association under an MP group of AMS2 is 1.1.1.1; if the collector identifier of the MP association under the outgoing MP group of the AMS2 is 1.1.1.3, the network management system determines that the collector identifier of the MP association under the incoming/outgoing MP group of the AMS2 is a different collector, and the network management system displays the packet loss data of the AMS2 on the link between 1.1.1.1 and 1.1.1.3.

Fig. 3 is a schematic diagram illustrating packet loss data displayed in a transmission path of a service packet according to an embodiment of the present application.

Therefore, by applying the packet loss statistics implementation method of the packet provided by the application, the network device receives the first data request sent by the network management system. According to the first data request, the network equipment acquires a configured instance list, a configured collector list under each instance and an atomic measurement section AMS list. And the network equipment sends a first data response to the network management system, so that the network management system reconstructs and displays a transmission path of the service message according to the example list, the collector list configured under each example and the atomic measurement section AMS list. And the network equipment receives a second data request sent by the network management system. And according to the second data request, the network equipment acquires the packet loss data of each instance and the packet loss data of each AMS. And the network equipment sends a second data response to the network management system, so that the network management system displays the packet loss data of each instance and the packet loss data of each AMS in a transmission path of the service message.

Optionally, before step 110 in this embodiment of the application, a step in which the network device receives a third data request sent by the network management system and sends a third data response to the network management system is further included.

Specifically, an analyzer list page is displayed in the network management system, as shown in fig. 4, fig. 4 is a schematic diagram of the analyzer list page provided in the embodiment of the present application. In fig. 4, the parser list includes a status column, a device tag column, a parser identification column, a UDP port column, an instance number column, and a details column.

And if the network management system needs to acquire the related information and data of the analyzer, the network management system generates a third data request according to the IP address of the analyzer recorded in the equipment label column, wherein the third data request comprises an analyzer field. The third data request may be specifically as follows:

<INQA>

</INQA>

and if the network device receiving the third data request is the analyzer, the network device fills the attribute data of the analyzer in the analyzer field.

And the network management system sends a third data request to the network equipment, and after the network equipment receives the third data request, if the network equipment is an analyzer, the network equipment fills the attribute data of the analyzer in the field of the analyzer and generates a third data response.

And the network equipment sends a third data response to the network management system. And after receiving the third data response, the network management system acquires the attribute data of the analyzer from the third data response, and then determines that the network equipment is the analyzer. At this time, if the user inputs a click instruction, for example, the user clicks "instance details in the details column". The network management system generates a first data request and performs the steps 110-160.

After the network management system acquires the configured instance list, the collector list and the AMS list of the network equipment, the network management system displays the instance list, the collector list and the AMS list. As shown in fig. 5, fig. 5 is a schematic diagram of an example data page provided in the embodiment of the present application.

If the network device is not the analyzer, the network device discards the third data request.

Optionally, in this embodiment of the present application, the method further includes a step of marking, by the network device, the service packet to be counted.

Specifically, the network device obtains a first service packet, where the first service packet includes an IP header, and the IP header includes a ToS field. The first service packet further includes a feature attribute field, and the feature attribute field may specifically be a source IP address, a destination IP address, and the like.

According to the characteristic attribute field, the network device determines that the first service message is a message to be subsequently counted and belongs to the target service flow, and sets a fifth position included in the ToS field to generate a second service message. Note that the ToS field has 8 bits. In the embodiment of the application, the fifth bit is used as a dyeing bit to mark the service message.

Subsequently, the network device counts the marked second service packet belonging to the same target service flow, and forwards the second service packet through a transmission path for transmitting the second service packet, so that each network device (it can be understood that the network device configured with the MP) included in the transmission path counts the second service packet according to the set fifth bit.

Optionally, before step 110 in this embodiment of the present application, a step of configuring an instance in a network device and associating the instance with a service flow is further included.

Specifically, an instance corresponding to each service feature is configured according to the service feature (e.g., voice stream, video stream, etc.) of each service stream. In the embodiment of the present application, one example configures a service flow, and the service flow may be a unidirectional flow or a bidirectional flow. Wherein a bidirectional flow is logically two unidirectional flows in opposite directions.

In each instance, the network device associates a feature attribute of a service packet included in the service flow (the feature attribute may include a source IP address, a destination IP address, and the like). In one example, the service flows configured under example 1 are: "forward source-ip 10.1.1.1destination-ip 10.2.2.2". That is, the source IP address of the target service flow is 10.1.1.1, and the destination IP address is 10.2.2.2, and statistics is performed on the service packet sent from 10.1.1.1 to 10.2.2.2.

Optionally, in each instance, after the network device associates the feature attribute of the service packet included in the service flow, the network device further configures an MP and an AMS in the instance.

Specifically, when the network device is a collector, at each instance, the network device configures an MP identifier of an associated MP, where the MP identifier represents an MP associated with an interface of the network device; when the network device is an analyzer, in each instance, the network device sequentially configures an identifier of a collector and an identifier of an AMS that pass through a transmission path for transmitting the service packet.

It should be noted that, in the embodiment of the present application, the roles of the network device include a collector and an analyzer. The role configuration of the network device may be configured locally at the network device by an administrator in the form of a command line.

The packet loss statistics implementation method for the packet provided in the embodiment of the present application is described in detail below. Referring to fig. 6, fig. 6 is a flowchart of another packet loss statistics implementation method for a packet according to the embodiment of the present application. The method is applied to a network management system, and the packet loss statistics realization method of the message provided by the embodiment of the application can comprise the following steps.

The network management system generates a first data request, and the first data request is used for the network management system to obtain instance data configured in the network equipment. The instance data comprises a configured instance list, a configured collector list under each instance in the instance list and an AMS list.

Step 620, receiving a first data response sent by the network device, where the first data response includes the list of instances, the list of collectors configured under each instance, and the list of atomic measurement section AMS.

In the embodiment of the present application, the configured instance list, collector list and AMS list of the network device are shown in step 120 in the foregoing embodiment, and are not repeated here.

And the network equipment generates a first data response after acquiring the configured instance list, the collector list configured under each instance and the atomic measurement section AMS list.

And according to the example list, the collector list configured under each example and the atomic measurement section AMS list, reconstructing and displaying the transmission path of the service message by the network management system.
