Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a medium for detecting a link delay.
Background
At present, communication operators generally adopt a multi-port physical link aggregation mode in an Internet Protocol (IP) network for interconnection between networks, and use aggregation links for interconnection between devices. The delay is one of the important indexes reflecting the network quality between two network devices, and directly affects the quality of service signals flowing through the devices and finally affects the service perception of users.
For the time delay detection between network devices, usually, a test task is deployed between the network devices, and the network quality index of time delay is obtained by recording the test task. The following two situations are common practice:
in the first case: as shown in fig. 1, a Network Quality Analysis (NQA) test is deployed on network devices at both ends. The NQA analyzes the network performance and the service quality by sending the test message, and the time delay is an important test index.
In the second case: as shown in fig. 2, network probes are respectively connected to network devices at two ends, the network probes send network quality test messages, and test results are returned to a probe server for network performance and service quality analysis, where time delay is an important test index.
From the above two kinds of situation analysis, both the NQA test and the probe test construct a test message between tested links, for example, the delay and Packet loss rate test often uses the Internet Packet explorer (ping), which is an Internet Control Message Protocol (ICMP), to return the test result to the server for summary analysis.
However, when the aggregation link mode is used between two network devices, the test result shows the time delay of the aggregation link, and the two test methods cannot reflect the time delay of each member link.
In addition, at present, a few communication device manufacturers pay attention to the problem of link quality test in an aggregated link application scenario, and provide a method for performing quality test on a member link in an aggregated link, where a Two-way Active Measurement Protocol (TWAMP) is used to control reserved bytes in a message, and an aggregated member information related field is added, and before sending a test message, Two-end devices negotiate on which member link the test message is sent and received, that is, it is clear that a local end sending port and an opposite end reflection port are on the same member link, and a subsequent test message is sent and received on the member link, thereby implementing independent test and coverage on each member link.
The existing test method for the time delay of the aggregation link has the following defects:
both the NQA test and the probe test are constructed test messages. The NQA test takes the management IP or interface IP of the two-end equipment as a source and a destination address; the probe test is to construct a test message by taking the IP of the probes at two ends as a source address and a destination address. In the forwarding process of the aggregation link for the IP packet, a load sharing algorithm based on a triplet (source IP address, destination IP address, application protocol) or a quintuple (source IP address, source port, destination IP address, destination port, application protocol) is generally adopted to achieve the purpose of sharing different service flows in each member link in a balanced manner. Thus, the test message constructed in the NQA test and the probe test is calculated to be selected to a certain member link under the action of the aggregation link load sharing algorithm, and the test result of the aggregation link is actually the test result of the selected member link. The quality of the other member links is not measured and monitored.
In addition, a few device manufacturers add aggregated member information fields in reserved bytes of TWAMP control messages, and negotiate a method of sending ports and reflecting ports of two-end devices through the control messages before sending test messages, so that independent tests on all member links can be realized, but the definition and use of the reserved bytes are specified in the current unsolicited Comments (RFC) standard and belong to the customization of a few device manufacturers. The problem of intercommunication among different manufacturer devices exists, and practical application in the network is limited.

and S140, determining the time delay of each link in the aggregated links according to the first time delay and the second time delay.
According to the embodiment of the invention, the time delay of each link in the aggregation link can be detected.
It should be noted that, in the present invention, the ping command is executed on the network devices at both ends (set as the a-end network device and the B-end network device) by using the member link ports as the source interfaces, and the home-end member port returned by the ping message is recorded by configuring the command parameters.
In addition, the command format of each vendor device may be different, and may be queried through the product document thereof, taking hua as a router as an example, the command format may be the expression (1):
ping-i [ number of member link port ] -ri-a [ source IP address ] [ destination IP address ] (1)
Wherein, the source IP address and the destination IP address are respectively the interface IP addresses of the network equipment at the two ends of the tested aggregation link A/B. The i [ member link port number ] parameter identifies which member link port in the aggregated link the ping message originates from. The ri parameter identifies which member link port in the aggregated link to record from which to return when the ping message returns.
As an example, for a certain ping test command, the partial program code of which returns the result may be as follows:
<Router A>ping-i 100ge3/1/0/0-ri-a 211.137.47.1 211.137.47.2

from the above return results, it can be seen that the test packet is sent from the member link port 100GE3/1/0/0 in the aggregated link (Eth-Trunk10) of the a-side network device, and returns from the member link port 100GE3/2/0/0 of the a-side device after the B-side device responds, with a delay of 2 milliseconds.
Fig. 4 is a schematic diagram illustrating that two ends simultaneously perform link delay testing according to an embodiment of the present invention. As shown in fig. 4, assuming that the number of member links in the aggregated link between the a-side device and the B-side device is n, the a-side and B-side member link ports are respectively recorded as a1, a2 … An, B1, and B2 … Bn. And respectively carrying out ping test on the A-end equipment by taking the A1 and A2 … An ports as source ports, recording the returned time delay parameters of TA1 and TA2 … TAN, and recording the member port number (AX port) of the returned message.
Because the response of the ping test message of the a port is sent to the a port by the B port device, according to the aggregation link load sharing algorithm of the B port device, no matter from which member link port the a port device sends, as long as the source IP address and the destination IP address are not changed, the B port device will respond from the same member port. Thus, from the perspective of the a-side device, the AX ports are the same in the test results of the a1 and a2 … An ports. And recording that the B-end equipment is sent from the corresponding BX port through the corresponding relationship of the member ports at the two ends of the A/B.
Similarly, ping tests are respectively carried out on the B-end equipment By taking B1 and B2 … Bn ports as source ports, returned delay parameters are recorded as TB1 and TB2 … TBn, and member port numbers (By ports) of returned messages are recorded. According to the same principle, in the test results of the B1 and B2 … Bn ports, the By ports are the same. And through the corresponding relation of the member ports at the two ends of the A/B, the equipment at the A end is sent out from the corresponding Ay port.
Finding a test result corresponding to the Ay port in test results TA1 and TA2 … TAN of the A-end equipment, and marking the test result as TA'; and finding the test result corresponding to the Bx port in the test results TB1 and TB2 … TBn of the B-side equipment, and marking the test result as TB'.
As An example, according to the A/B two-end member port correspondence, for example, a first link is between the A1 port and the B1 port, a second link is between the A2 port and the B2 port, and so on, and An nth link is between the An port and the Bn port. The method comprises the steps that an A1 port is used as a source port to conduct ping test on an A-end device, ping messages are sent out from an A1 port to a B-end device, the B-end device is supposed to return to an A3 port of the A-end device from a B3 port after answering, and namely A3 rd link is a public link. A ping message sent from any port of the a-side device returns through the 3 rd link.
Similarly, a B1 port on the B-side device performs ping test for the source port, a ping message is sent from the B1 port to the a-side device, and it is assumed that the a-side device returns to the B2 port of the B-side device from the a2 port after responding, that is, the 2 nd link is a public link. A ping message sent from any port of the B-side device returns via the 2 nd link.
In the 2n test results of the a terminal and the B terminal, paths taken by only one test result are overlapped, for example, the a terminal device a2 sends A3 back and the B terminal device B3 sends a B2 back in fig. 4, and the test results under the same path are theoretically the same, that is, TA2 — TB 3. However, considering the test accuracy and the difference of the response time delay of the device except the transmission time delay, the two results are only relatively close, the relative influence of the response time delay of the device is small when the ports of the device are all opened in an icmp-fast mode, and the average value calculation can be carried out. The common path is easy to find through the belt-ri parameter and the port corresponding relation, and the time delay of the common path is recorded. And the time delay of each independent link is the sum of the test results at the two ends of the link and the subtraction of the common path.
Finally, respectively calculating time delays T1 and T2 … Tn of each member link between the devices at two ends of the A/B by using formulas (2), (3) and (4)
T1＝TA1+TB1-(TA’+TB’)/2 (2)
T2＝TA2+TB2-(TA’+TB’)/2 (3)
Tn＝TAn+TBn-(TA’+TB’)/2 (4)
Fig. 5 is a schematic diagram illustrating a single-ended link delay test according to an embodiment of the present invention. As shown in fig. 5, when a certain end network device does not have the collection test condition, the following test and calculation method may be adopted to measure the delay of the member link in the aggregated link.
As an example, assume that the number of member links in an aggregated link between an a-side device and a B-side device is n, and the B-side device does not have a collection test condition. The a-terminal member link ports are recorded as a1, a2 … An. And respectively carrying out ping test on the A-end equipment by taking the A1 and A2 … An ports as source ports, recording the returned time delay parameters of TA1 and TA2 … TAN, and recording the member port number (AX port) of the returned message. And finding out a test result corresponding to the Ax port from the test results TA1 and TA2 … TAN of the A-side equipment, and marking the test result as TA'. In this scenario, it is approximately considered that the time delay of transceiving two channels on the same physical link is the same, i.e. the round-trip path is 2 times that of the single round-trip path. Each physical link delay can therefore be approximated using the relationship of the common backhaul path.
Respectively calculating the time delay T1 and the time delay T2 … Tn of each member link between the devices at the two ends of the A/B by using the following formulas:
T1＝2TA1-TA’ (5)
T2＝2TA2-TA’ (6)
Tn＝2TAn-TA’ (7)
the invention is suitable for detecting the time delay of the member link of the network equipment under the condition of using the aggregation link for interconnection. Meanwhile, two situations that both ends of the network equipment can be used for acquisition test and only one end of the network equipment can be used for acquisition test are considered.
The invention realizes the specific measurement of the time delay index of each member link in the aggregation link between the IP network devices. The invention is a universal measuring method, solves the blind point in time delay quality monitoring under the application environment of the IP network aggregation link by utilizing the technical characteristics of the load sharing of the network equipment aggregation link, can be applied to the networking environment of multiple manufacturers, and has good application prospect.
