Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for measuring packet loss under a Tag model, and an electronic device.
Background
The Two-Way Active Measurement Protocol TWAMP (Two-Way Active Measurement Protocol) provides a flexible approach for establishing a monitoring session and exchanging information between a sender and a receiver of a monitoring data packet, and comprises Two groups of protocols: a set of protocols, called control protocols, is used to establish performance measurement sessions; another set of protocols is used for the transmission and reception of performance measurement probes, called test session protocols. The TWAMP test may measure packet loss, delay, and jitter indicators for both directions of the network.
The TWAMP test is for a specific service entry, after the transmitting end sends a measurement packet, the transmission end sends the measurement packet to the reflecting end on the NNI line, after the reflecting end receives the service packet and the measurement packet, the service packet is sent to the UNI side of the client, the source IP address, the destination IP address, the source port number and the destination port number of the measurement packet of the TWAMP are exchanged, and then the exchanged measurement packet is sent back to the transmitting end, thereby completing a complete measurement process, as shown in fig. 1.
In the current TWAMP measurement model of the packet transport network, a virtual local area network Tag VLAN Tag is configured for a service in the call-up direction (from the user side to the network side) or the call-down direction (from the network side to the user side) of the reflection end, Tag actions change VLAN information carried in a message, and when the reflection end finally returns the message, the reflection end needs to restore the VLAN information of the Tag action change message, and return the restored message to the transmission end. The above measurement process has the following problems: the VLAN configuration action is configured in the following direction, for example, deletion is performed, that is, a service packet VLAN sent by the reflection end is deleted and then sent to a UNI (User Network Interface), because the TWAMP measurement packet and the service packet have the same logic, the VLAN in the TWAMP measurement packet is also deleted, and the deleted VLAN needs to be restored in the measurement packet returned to the transmission end, so that the transmission end considers that the packet returned by the reflection end is correct only when receiving the packet returned by the reflection end, and the accuracy of calculated packet loss is not affected, and the specific process is shown in fig. 2.
However, because the reflective end device sometimes processes the abnormal or the chip VLAN Tag cannot restore the message before the Tag action in some scenes, the VLAN information is asymmetric with the transmitting end when the reflective end returns the message, and after the transmitting end receives the message returned by the reflective end, the transmitting end considers that the message is not an expected message and discards the expected message, which results in greatly reducing the accuracy of the performance of calculating packet loss and the like by the transmitting end.

Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
The embodiment of the invention solves the key problem of how to feed back the information of the message changed by the Tag action of the reflection end to the transmission end, thereby reducing the packet loss of the transmission end caused by the self processing logic defect of the reflection end.
To solve the problem, firstly, the processing logic of the packet switch chip at the reflection end for the VLAN Tag in the prior art is analyzed, please refer to table 1:
TABLE 1
A message received from a transmitting end is intended for the reflecting end in the down-call direction (i.e. from the NNI side to the UNI side), and the following two situations may occur.
In the first case: the "identification" (NNI) - - - - - "increase" (UNI) UNI side service rule only matches PORT (PORT), does not match relevant rules such as VLAN, and corresponds to the 4 processing modes of table 1, which are respectively mode 1 corresponding to sequence number 1, mode 2 corresponding to sequence number 2, mode 3 corresponding to sequence number 3, and mode 4 corresponding to sequence number 4.
According to the mode 1, under the condition of TWAMP message (without VLAN) at NNI side, a layer of VLAN is added to UNI side, the value is assumed to be A, the message measurement message of VLAN A is carried, and the packet switching chip at the reflection end can delete VLAN A.
According to the method 4, if the twimp packet at the NNI side carries a layer of VLAN, which is a layer of VLAN a, with B, the added VLAN may be deleted and the original VLAN may be retained.
According to the method 3, if the identification is "identification — addition", the chip does not add a layer of VLAN a, but the chip is deleted, so that the VLAN carried by the TWMAP message is deleted as B. That is because mode 1 and mode 3 are mutually exclusive in the above table. In table 1, the "behavior" and "action" in the second and third columns are the same in the mode 1 and the mode 3, but the "result after chip processing" in the fourth column is different in the result. The result of the method 1 is that the VLAN a in the "action" is added, but the result of the method 1 is that the VLAN a in the "action" is not added, and the VLAN B in the original message is retained.
In the second case: "identify" (NNI) -delete "(UNI), UNI-side traffic rules match only PORTs (PORTs), do not match relevant rules like VLAN.
When the NNI side service and TWAMP packet are downloaded with a layer of VLAN, the VLAN device cannot recognize the message (because recognition is not required, because the service rule on the UNI side is Port-based, it is not necessary to analyze whether there is a VLAN in the packet and the value of the VLAN), and the message is deleted directly by the "delete" action of the download. Since the TWAMP message does not have VLAN and VLAN value at all, the packet switching chip at the reflection end cannot restore (add) the VLAN, and therefore, the TWAMP message finally reflected from the NNI side has no VLAN. However, after the transmitting end receives the message returned by the transmitting end, the message is considered to be wrong, and the message is discarded.
Based on the above analysis, an embodiment of the present invention provides a method for measuring packet loss under a Tag model, including a reflection end method and a transmission end method.
Fig. 3 is a schematic flow chart of a method for measuring packet loss under a Tag model according to a reflection end method of the present invention, where the method for measuring packet loss under the Tag model shown in fig. 3 includes:
s100, receiving a TWAMP measurement message sent by a transmitting terminal;
s101, adding local VLAN Tag information to a reserved field of the TWAMP measurement message, forming a reflection message and then sending the reflection message, so that a transmitting end can restore the reflection message through the VLAN Tag information and then measure packet loss;
the VLAN Tag information comprises a Tag action identifier and a VLAN value.
The embodiment of the invention provides a method for measuring packet loss under a Tag model, which increases VLAN Tag identification and Tag VLAN value in a reflection message under a Tag business model, so that a transmitting end can confirm whether a reflecting end has Tag action and whether the reflecting end increases VLAN. The method of the invention does not need to change the existing TWAMP protocol specification and flow, only needs to add the VLAN Tag identification and Tag VLAN value from the reflected message, can lead the transmitting end to analyze and check the returned message, accurately obtains the performance of the packet loss or the packet loss rate of the test service, and greatly improves the accuracy of the packet loss measurement.
The method of the embodiment of the invention is particularly suitable for the condition that the message is discarded by the transmitting terminal due to the fact that the message returned is incorrect sometimes because of processing errors or after the VLAN Tag is configured by the service at the reflecting terminal.
Specifically, in the current TWAMP test message, the message format of the reflection end is as follows:
step S101, adding local VLAN Tag information to a reserved field of the TWAMP measurement packet, forming a reflection packet, and then sending the reflection packet, specifically including: and filling own action and VLAN Value information into the reserved field of the message by using the reserved field in Padding in the current message.
The VLAN Tag information comprises a Tag action identifier and a VLAN Value, and is respectively represented in the message through a Flag field and a VLAN Value field.
Specifically, the format of the reflection message is as follows:
specifically, the VLAN Tag information is configured with 3 bytes, where the Tag action identifier, i.e., Flag, occupies 1 byte, and the VLAN Value, i.e., VLAN Value, occupies 2 bytes.
In an optional embodiment, VLAN Tag information configured by the following method is added to the reserved field of the TWAMP measurement packet:
if the local test service is not configured with VLAN Tag, setting the Tag action identifier as an unconfigured identifier;
and if the local test service is configured with VLAN Tag, setting the Tag action identifier as a configured identifier, and setting the VLAN value according to the TWAMP measurement message, the local behavior configuration and the action configuration.
Specifically, the unconfigured flag may be set to 0, and the configured flag may be set to 1. If the test service corresponding to the reflection end is not configured with VLAN Tag, setting Flag to 0 in the reflection message; if the VLAN Tag is not configured for the test service corresponding to the reflection end, the Flag is set to be 1 in the reflection message, and meanwhile, the Value of the VLAN Value is set.
In other words, Flag is equal to 1, which indicates that there is a Tag action, Vlan Value is equal to a, which indicates that the reflection end adds a VALN a to the packet; and the Vlan Value is 0, which indicates that the reflection end does not add VALN to the message.
Specifically, according to table 1, if the local test service is configured with a VLAN Tag, the Tag action identifier is set as a configured identifier, and the VLAN value is set according to the TWAMP measurement packet, the local behavior configuration, and the action configuration, which specifically includes:
if the TWAMP measurement message has no VLAN information, the local behavior configuration is identification, and the action configuration is VLAN increase, after the exchange chip increases the VLAN, the Tag action identifier is set as the configured identifier, and the VLAN value is set as the VLAN value increased by the exchange chip;
if the TWAMP measurement message has no VLAN information, the local behavior is configured to be unidentified, and the action is configured to be added with VLAN, after the exchange chip is added with VLAN, the Tag action identifier is set as a configured identifier, and the VLAN value is set as the VLAN value added by the exchange chip;
if the TWAMP measurement message contains VLAN information, local behavior configuration is identification, and action configuration is VLAN increase, the Tag action identifier is set as a configured identifier and the VLAN value is set as 0 after the exchange chip increases the VLAN;
if the TWAMP measurement message contains VLAN information, the local behavior is configured to be unrecognized, and the action is configured to be added with VLAN, after the exchange chip adds VLAN, the Tag action identifier is set as a configured identifier, and the VLAN value is set as the VLAN value added by the exchange chip.
For example, for the two cases mentioned above where the mode 1 and the mode 3 are mutually exclusive, if there is no VLAN in the original measurement packet in the mode 1, after identifying that a layer of VLAN is added, the Flag of the reflection end packet may be set to 1, and meanwhile, the VLAN Value is filled with a, and after the transmission end resolves that the Flag is 1 and the VLAN Value is a, it may be determined that the reflection end is the VLAN added, and the packet is considered to be the reflection end and should not be discarded, and the detailed results are shown in the following table.
The results of the processing performed in the embodiment of the present invention with respect to table 1 are shown in table 2:
fig. 4 is a schematic flowchart of a method for measuring packet loss under a Tag model at a transmitting end in an embodiment of the present invention, where the method for measuring packet loss under the Tag model shown in fig. 4 includes:
s200, receiving a reflection message sent by a reflection end;
s201, analyzing VLAN Tag information in the reflection message; and restoring the reflection message according to the Tag action identifier and the VLAN value in the VLAN Tag information so as to measure packet loss.
In this embodiment, the reflected packet processed by the reflection end is identified, and the transmission end determines whether to discard the packet based on the VLAN Tag identifier and the Tag VLAN value in the reflected packet, so as to complete correct packet processing. Please refer to the description of the foregoing embodiments for the VLAN Tag information and the format of the reflection packet, which is not described herein again.
In an optional embodiment, the restoring the reflection packet according to the Tag action identifier and the VLAN value in the VLAN Tag information specifically includes:
if the Tag action identifier is not configured, directly taking the reflection message;
and if the Tag action identifier is a configured identifier, judging whether a VLAN is added to the reflection message at the reflection end according to the VLAN value.
Further, if the fact that the reflection end is added with the VLAN is judged and known, the added VLAN value is obtained according to the VLAN value in the VLAN Tag information.
Specifically, after the reflection enclosure is sent back to the transmitting end, the transmitting end may analyze information of Flag and VALN Value when analyzing the reflection packet, and determine whether the reflecting end changes the packet through the VALN Tag. If the Flag value is 0, the reflection end does not perform VLAN Tag action, and the transmission end is directly used; if the transmitting end confirms that the VALN Tag exists through the Flag bit, the transmitting end can restore the message, so that the phenomenon that the transmitting end discards the message and calculates performance data such as packet discarding and the like because the transmitting end cannot correctly process the message can be effectively avoided.
To sum up, in the measurement scheme of the Tag service model, the reflection end in the embodiment of the present invention does not need to change the existing TWAMP protocol specification and flow, and only needs to add the identifier of the VLAN Tag and the Tag VLAN value from the reflection packet, so that the transmission end can analyze and check the returned packet, accurately obtain the performance of the packet loss or the packet loss rate of the test service, and greatly improve the accuracy of the packet loss measurement.
