Description

Method and device for measuring service quality

Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a service quality measurement method and apparatus.

Background technique

When operators provide network services to customers, they need to monitor the performance and fault conditions of customer services for the purposes of operation and maintenance and fault definition. For common IP services, IETF (The Internet Engineering Task Force) defines TWAMP (Two-Way Active Measurement Protocol) in RFC5357, which can be used to measure and monitor the performance of customer services. In the networking shown in Figure 1, the operator wants to know the quality of the service transmission it provides to the customer. It will be in PE1 (where PE is the abbreviation of Provider Edge, the carrier edge router, and CE is the abbreviation of Customer Edge. The TWAMP protocol is used between the user edge router and the PE2 to simulate the customer service for measurement. According to RFC5357, the functional block diagram of the measurement scheme is shown in Figure 2. The TWAMP measurement is performed between the Session-Sender and the Session-Reflector, and the Control-Client and Server are mainly configured for TWAMP measurement.

As the security requirements of the customer are improved, the carrier often provides device-level protection at the edge of the network to improve network security. As shown in Figure 3, the client's headquarters organization uses a double span. The mode is connected to the PE2 and PE3 at both ends of the carrier network. The PE2 can be configured as the backup device of the PE2. When the PE2 or PE3 fails, or PE2 or PE3 is restarted due to device upgrade, The customer service between CE1 and CE2 is not interrupted. However, in the networking scenario shown in Figure 3, TWAMP cannot be deployed on the carrier network because the carrier network provides IP services, and the IP service is based on one-way forwarding technology. Assume that PE2 acts as a Session-Sender, PE1. As a Session-Reflector, according to the measurement function framework shown in Figure 2, the TWAMP measurement protocol can be run between PE2 and PE1. However, the service quality measurement message sent by PE2 may be returned to PE3 after PE1 processing, resulting in TWAMP. The measurement protocol does not interact properly.

While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

First embodiment

The embodiment of the present disclosure provides a service quality measurement method, which is applied to a backup router of a first router at a session transmitting end. As shown in FIG. 4, the service quality measurement method includes:

S401. Receive a first reflection packet sent by a second router that is in a session reflection end.

The first reflective packet is a data packet generated after the second router receives the measurement packet sent by the first router at the session transmitting end.

The first router may correspond to PE1 in FIG. 3, the backup router corresponds to PE3 in FIG. 3, and the second router corresponds to PE2 in FIG. 3, so the following descriptions about the first router, the second router, and the backup router are performed. PE1, PE2, and PE3 are taken as examples. PE1 is defined as a session transmitting device, PE2 is defined as a session reflector device, and PE3 is defined as a forwarding device. When PE1 sends a measurement packet to PE2, PE2 processes the measurement packet according to the relevant protocol (such as RFC5357) to generate a first reflection packet. When PE2 sends the first reflection packet to PE1, PE1 calculates the service according to the first reflection packet. Quality measurement result; when PE2 sends the first reflection packet to PE3, it proceeds to S402.

S402. Generate a second reflection packet according to the first reflection packet.

After receiving the first reflection packet sent by the PE2, the PE3 processes the first reflection packet to generate a second reflection packet. For example, adding a first receiving time that the PE3 receives the first reflective packet in the first reflective packet, and generating a second reflective packet, so that the PE1 calculates the session transmitting end and the session reflection according to the first receiving time that the PE3 receives the first reflective packet.

The PE3 sends the generated second reflection packet to the PE1, so that the PE1 calculates the service quality measurement (such as calculating the packet loss rate and the two-way delay). In this way, even if the PE2 does not directly send the first reflection packet to the PE1, it can be forwarded through the PE3, thereby implementing the service quality measurement by the TWAMP technology, so that the TWAMP technology can deploy the application in a more complex network environment, and the TWAMP pair is improved.

Specifically, the first transmission packet records the first transmission time that PE1 sends the measurement packet and the second reception time that PE2 receives the measurement packet. The first transmission time, PE2, in which the PE1 sends the measurement packet is recorded in the second reflection packet. The second reception time of the measurement packet is received and the first reception time of the first reflection packet is received by the PE3. In this way, PE1 may calculate a one-way delay from the session transmitting end to the session reflection end according to the first sending time and the second receiving time recorded in the second reflection packet, and according to the first sending time and the first recorded in the second reflection packet. A receiving time calculates a two-way delay between the session transmitter and the session reflector.

Step 2: The measurement reflection module processes the received measurement message according to the requirements of RFC5357, constructs a measurement reflection packet (ie, the first reflection packet), and transmits it, and then proceeds to step 3 or step 4.

The measurement reflection packet records the reception time of the measurement packet (ie, the second reception time), measures the sequence number and the packet transmission time (ie, the first transmission time) in the packet, and the sequence number and the packet of the measurement reflection packet. Time and other information.

Step 3: If the measurement and delivery module receives the measurement reflection packet, the service quality measurement result is calculated according to the requirements of RFC5357, and the process ends.

Step 5: After the measurement packet receiving module receives the measurement reflection packet of the reflection packet forwarding module, the service quality measurement result is calculated and ended.

If the packet loss rate is calculated, it can be calculated according to the requirements of RFC5357. If the two-way delay is calculated, the calculation should be based on the time when the packet forwarding module receives the packet, that is, the first transmission time and the first reception. Time, calculate the two-way delay between the session transmitter and the session reflection end.

In summary, in the service quality measurement method provided by the embodiment of the present disclosure, when the router at the session reflection end sends the reflection packet to the backup router of the router that sends the measurement packet, the reflective packet can be forwarded by the backup router to the router that sends the measurement packet.
