The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In order to better understand the embodiments of the present invention, the related concepts of SCTP are first described.

1) Transport Address: is a binary combination of IP address and port, unique Identifies the sender and receiver of a message.

2) Endpoint: A collection of transport addresses with the same port. For example, Endpoint=[IP 1 , IP2, ... , ΙΡη: Port].

3) Association: As a connection-oriented transport protocol, before the application layer transfers data from one endpoint to another, the two endpoints exchange information first to establish a communication relationship. This communication relationship is coupled. E.g,

Association={[ ΙΡ11,ΙΡ12,...,ΙΡ1η: Portl] :[IP21,IP22,...,IP2n: Port2]}

4) Primary Transport Address: Relative to the alternate transport address, the endpoint uses the primary transport address to transmit user data, and does not use the alternate transport address for load sharing. When the primary transport address is inactive, the alternate transport address is enabled to transmit data.

5) Path: A path is a vector with a starting identifier relative to an endpoint and is a source-destination address pair. When the destination transport address is inactive, the path to the destination address of the destination endpoint is considered faulty.

6) multi-homing: If there are multiple transmission addresses in the two SCTP endpoints, there are multiple transmission paths within the SCTP coupling. Normally, one of the paths is used to transmit traffic. This path is called the primary path. When the primary path is deactivated (inactive), the service switches to another active alternate path.

1 is a schematic structural diagram of a multi-homing system according to an embodiment of the present invention. The system includes two ports, namely, an endpoint A and an endpoint B. The endpoint A has two IP addresses, namely IP1 and IP2, and the endpoint B also has Two IP addresses, IP3 and IP4.

When endpoint A and endpoint B communicate, endpoints [[IP1, IP2:100], endpoints B[IP3, IP4:100], are coupled {[IP1JP2:100]:[IP3JP4:100]}. Figure 1 shows two paths: Path 1 ( Pathl ) and Path 2 ( Path 2 ). Actually, depending on the definition of the path, there can be up to 4 paths between the two endpoints.

In addition, in the prior art, a heartbeat request message may be used to detect an on/off state of the backup path. For example, port A sends a heartbeat request packet to port B. The source and destination addresses of the heartbeat request packet correspond to the source and destination addresses of the alternate path respectively. Port A starts the timer when sending heartbeat request packets. If the heartbeat response packet of the corresponding heartbeat request packet sent by port B is not received after the timer expires, the backup path between port A and port B is disconnected. If the timer expires, port B is received. The heartbeat response message of the corresponding heartbeat request message sent, This indicates that the alternate path between port A and port B is connected.

However, in the prior art, the heartbeat request message can only detect the on/off state of the alternate path, and cannot further detect the communication quality of the alternate path, for example, cannot detect the QoS parameter of the alternate path.

In order to implement the detection of the communication quality of the alternate path, the heartbeat request message is extended in the embodiment of the present invention so that the relevant parameters are carried in order to implement the detection of the communication quality. See the following examples for details.

2 is a schematic flowchart of a method for detecting a path communication quality according to an embodiment of the present invention, including: Step 21: A sending end sends a heartbeat request message to a receiving end, where the heartbeat request message includes a source address of a path to be detected and The destination address and the first field, the first field indicating that the heartbeat request message is used for path communication quality detection.

The system shown in FIG. 1 is taken as an example. If the path to be detected is path 2, and the source address and the destination address of the path 2 are IP2 and IP4, respectively, the endpoint A sends a heartbeat detection packet to the endpoint B, and the The source address and destination address in the header of the heartbeat detection packet are filled with IP2 and IP4, respectively.

In addition, the first field is also required to be carried in the existing heartbeat request packet, and the first field may be referred to as a heartbeat usage field, and the heartbeat usage field is used for the heartbeat usage field. The heartbeat request message corresponding to the identifier is an ordinary heartbeat request message or a heartbeat request message for communication quality detection.

The Heartbeat Usage field can be included in the Sender-Specific Heartbeat Info section of the mind request.

Further, the Heartbeat Usage field can take a type length value (Type Length

Value, TLV) format.

Specifically, referring to FIG. 3, the heartbeat request message includes a heartbeat information part, and the heartbeat information part is composed of a Heartbeat Info Type, a Heartbeat Info Length, and a Sender-Specific Heartbeat Info. Part of the composition. The Heartbeat Usage field is included in the Sender-Specific Heartbeat Info section, and the heartbeat information part is in the TLV format. The Heartbeat Usage Type and the Heartbeat Request are used. The Heartbeat Usage Length and Heartbeat Usage are composed of Heartbeat Usage Length. The value of the Heartbeat Usage Type is 1 and the value of the Heartbeat Usage Type can be defined as 2. The value of Heartbeat Usage Length can be defined as 4, and the value of Heartbeat Usage is used to indicate that the heartbeat request message is The heartbeat request message is a heartbeat request message for the path communication quality check. For example, when the value is 0, it indicates that it is a normal heartbeat request message. When the value is 1, it indicates that the heartbeat is used for path communication quality detection. Request a message.

Step 22: The sending end receives the heartbeat response message corresponding to the heartbeat request message, and determines the communication quality of the path to be detected according to the heartbeat request message and the heartbeat response message.

The foregoing communication quality may be the number of lost packets or the hopping of the content of the packet. Further, the number of lost packets may be the number of packets lost for packets of different lengths. The number of packet loss and the detection of the hopping condition can be specifically referred to the following embodiments.

In this embodiment, the existing heartbeat request message is extended, and the communication quality of the path is detected according to the heartbeat request message.

4 is a schematic flowchart of another embodiment of a method for detecting path communication quality according to the present invention, including: Step 41: End point A performs initial setting.

Wherein, the initial settings can include:

(1) setting a first counter and a second counter, and setting an initial value of the first counter and the second counter to 0, wherein the first counter is configured to perform a number of heartbeat request messages for detecting communication quality Counting, the second counter is configured to count the number of received heartbeat response messages corresponding to the heartbeat request message used to detect the communication quality.

(2) A transmission cycle timer is started, which is used to indicate a period of sending a heartbeat request message, that is, a heartbeat request message is sent when the transmission cycle timer expires.

(3) The detection period timer is started, and the detection period timer is used to indicate the detection period, that is, the detection ends when the detection period timer expires.

The value of the above-mentioned transmission cycle timer and the value of the detection cycle timer can be set according to actual needs.

Step 42: After the sending loop timer expires, the endpoint A sends a heartbeat request packet to the port B, and the value of the heartbeat request packet use field of the heartbeat request packet is set to indicate that the heartbeat request packet is used for communication quality detection. Value.

For example, if the value of the heartbeat request message use field is 1 indicating that the heartbeat request message is used for communication quality detection, set the value of the heartbeat request message use field to 1.

In addition, the source address and the destination address of the packet header of the heartbeat request packet may be the alternate path, and the source and destination addresses corresponding to the alternate path are IP2 and IP4. The source address and destination address in the header of the heartbeat request packet are IP2 and IP4, respectively.

Step 43: Endpoint A increments the value of the first counter by one after each of the above heartbeat request messages.

Step 44: After receiving the heartbeat request packet, endpoint B sends a corresponding heartbeat response packet to port A.

The source address and the destination address of the heartbeat response packet are in an interchangeable relationship with the source address and the destination address of the corresponding heartbeat request packet. The source and destination addresses of the heartbeat request packet are IP2 and IP4 respectively. , the source address and destination address of the corresponding heartbeat response are IP4 and IP2, respectively.

In addition, the payload content of the heartbeat response message is the same as the payload content of the corresponding heartbeat request message when no message content hopping occurs.

Step 45: Endpoint A increments the value of the second counter by one after each receiving a heartbeat response message corresponding to the heartbeat request message.

The port A can determine whether to correspond to the heartbeat request packet according to the source address and the destination address in the heartbeat response packet.

In addition, as the transmission cycle timer continuously times out, the heartbeat request message can be repeatedly transmitted, and the corresponding heartbeat response message is received, that is, the above steps 42-45 can be repeatedly performed.

Step 46: After the detection period timer expires, endpoint A calculates the packet loss rate.

Wherein, assuming that the count value of the first counter is A and the count value of the second counter is B, the calculation formula of the packet loss rate is: (A-B) /A.

In this embodiment, the packet loss rate is calculated by using the heartbeat request message for communication quality detection and setting a counter.

FIG. 5 is a schematic flowchart of another embodiment of a method for detecting path communication quality according to the present invention, including: Step 51: End point A performs initial setting. Detection.

In this embodiment, the initial settings include:

(1) setting a plurality of first counters and a plurality of second counters, and setting initial values of the first counter and the second counter to 0, wherein each of the first counters is used for respectively for different padding lengths The number of heartbeat request messages for detecting the communication quality is counted, and each second counter is divided. Do not use the number of received heartbeat response messages to count.

For example, the length of the packet that can be detected in this embodiment is as shown in Table 1:

Table 1

When the length of the message that can be detected is nine as shown in Table 1, nine first counters and two second counters corresponding to each of the first counters may be respectively set for the statistical length of 8, 16 respectively. , 32, 64....1400 4 packet loss rate.

(3) The detection cycle timer is started, and the detection cycle timer is used to indicate the detection cycle, that is, the detection ends when the detection cycle timer expires.

Step 52: After the sending loop timer expires, the endpoint A sends a heartbeat request packet to the endpoint B, and the value of the heartbeat request packet use field of the heartbeat request packet is set to indicate that the heartbeat request packet is used for communication quality detection. The value, as well as the heartbeat request message is filled with a certain length of message content.

Referring to FIG. 6, on the basis of the previous embodiment, the heartbeat request message in this embodiment further includes a Fill field, which can be in a TLV format, and is filled in type (Fill Type) and filled in length (fill). Length ) and the fill content ( Fill Content ). The value of the Fill Type can be a predefined value, for example, 3, and the value of the Fill Content is filled according to the pre-configured content, and the value of the Fill Length is set according to the length of the content of the Fill Content. For example, if the configuration is populated as shown in Table 1, Fill Content can fill each byte to 0x55. A total of 8 bytes of content, at this time, the value of Fill Length is 8; or, Fill Content can fill each byte of OxAA, a total of 16 bytes of content, at this time, the value of Fill Length is 16. This is a length of 8 bytes (Byte), the second time can also fill the content of 8 bytes (Byte), or the second can fill the content of 16 bytes (Byte) . The content of each fill can be filled in a random manner or in a preset manner.

Further, in order to improve the accuracy of the hopping detection, the content filled in the message needs to be guaranteed that each bit (bit) will be filled with 0 and filled with 1. For example, for a byte, the content of the -time padding is 0x55, that is, 0101. In the subsequent message, it is necessary to ensure that the highest bit has been filled with 1, the second highest bit has been filled with 0, and the lower low bit is filled. In the case of 1, the lowest bit has a case of being filled with 0. Specifically, the content to be filled next time is 0xAA.

Step 53: After transmitting one of the above heartbeat request messages, the endpoint A increases the value of the first counter corresponding to the length of the sent heartbeat request message by one.

For example, if the length of the content of the sent heartbeat request message is 8, the value of the first counter for counting the transmission of the heartbeat request message with the padding length of 8 is increased by one.

Step 54: After receiving a heartbeat request packet of a certain padding length, the endpoint B sends a heartbeat response packet with a corresponding padding length to the port A. After the address is exchanged, for example, the source address and the destination address of the received heartbeat request message are IP2 and IP4, respectively, and the source address and the destination address of the heartbeat reply message can be filled with IP4 and IP2, respectively, for the heartbeat request. The rest of the message, especially the padding content of the heartbeat request message, can be completely copied to the corresponding location of the heartbeat response message.

Step 55: Endpoint A increases the value of the corresponding second counter by one after each receiving a heartbeat response message with a certain padding length.

For example, if the length of the received heartbeat response message padding is 8, the value of the second counter used for receiving the heartbeat response message with the padding length of 8 is incremented by one.

In addition, as the transmission cycle timer continuously times out, the heartbeat request message can be repeatedly transmitted, and the corresponding heartbeat response message is received, that is, the above steps 52-55 can be repeatedly executed.

Step 56: After the detection period timer expires, the endpoint A calculates the packet loss rate of the packet of the corresponding length. If the count values of the first counter and the second counter for counting the padding content of length 8 are A1 and B1, respectively, the packet loss rate of the packet of length 8 can be obtained: (A1-B1) /A1 ; Assuming that the count values of the first counter and the second counter for counting the padding content of length 16 are A2 and B2, respectively, the packet loss rate of the packet of length 16 can be obtained: (A2) -B2) /A2. Similarly, the packet loss rate of the remaining length packets can be obtained.

In this embodiment, the packet loss rate of packets of different lengths can be calculated by using a heartbeat request packet for the communication quality detection and setting a counter corresponding to the length of the packet.

FIG. 7 is a schematic flowchart of another embodiment of a method for detecting path communication quality according to the present invention, including: Step 71: End point A performs initial setting.

Different from the previous embodiment, this embodiment can realize the detection of the hopping variable by detecting the content of the padding.

In this embodiment, the initial settings include:

(1) Set the trip counter and set the initial value of the trip counter to 0.

(2) A transmission cycle timer is started, which is used to indicate a heartbeat request packet transmission period, that is, a heartbeat request message is sent when the transmission cycle timer expires.

Step 72: After the sending loop timer expires, the endpoint A sends a heartbeat request packet to the endpoint B, and the value of the heartbeat request packet use field of the heartbeat request packet is set to indicate that the heartbeat request packet is used for communication quality detection. The value, as well as the heartbeat request message is filled with a certain length of message content.

For the specific filling method, refer to the previous embodiment.

In addition, endpoint A also needs to record the padding information of the heartbeat request message. For example, a padding request message with a source address and a destination address of IP2 and IP4 respectively is filled with: 8 bytes in total, and each byte is filled with 0x55. Further, in a scenario in which a plurality of lengths can be filled, it is also necessary to record the length of the padding content, such as the length of the record padding: 8.

Step 73: After receiving the heartbeat request packet, the endpoint B sends a corresponding heartbeat response packet to the port A.

Step 74: After receiving a heartbeat response message, the endpoint A compares the padding content in the heartbeat response message with the padding content of the corresponding heartbeat request message. If there is a content hopping, each hop changes to a bit, The count value of the trip counter is incremented by 1. If the corresponding heartbeat request packet and the heartbeat response packet are determined according to the source address and the destination address, the endpoint A can compare the padding content of the corresponding heartbeat request packet with the heartbeat response packet. Fill the content and get the jumps. For example, if the source address and the destination address of the heartbeat request packet R1 are IP2 and IP4 respectively, the source address and destination address of the received heartbeat response message A1 are IP4. IP2, compare the fill content F1 of R1 and the fill content F2 of A1. If F1 and F2 are the same, it means there is no jump. If a certain bit of F1 and F2 is different, it is determined that the jump number is 1, similarly, after comparison, Get the jump number.

In addition, if the endpoint A determines the heartbeat request packet and the heartbeat response packet according to the source address and the destination address, the endpoint A continues to determine the corresponding heartbeat request packet and the heartbeat response packet according to the fill length Fill Length. Then, the padding content of the corresponding heartbeat request message and the padding content of the heartbeat response message are compared to obtain a hopping number. For example, if the source address and the destination address of the heartbeat request message R1 are IP2 and IP4 respectively, the source address and destination address of the received heartbeat response message A1 are IP4 respectively. For IP2, you cannot directly compare the fill content F1 of F1 and the fill content F2 of A1 in the previous scene. Instead, you need to obtain the Fill Length part of R1 and the Fill Length part of Al, if the Fill Length part of R1 and the Fill of Al are The length part is the same, and the filling parts of the filling parts F1 and A1 of R1 are further compared. If F1 and F2 are the same, it means that there is no jump. If a certain bit of F1 and F2 is different, the jump number is determined to be 1, similar to the comparison. , get the jump variable.

In addition, as the transmission cycle timer continuously times out, the heartbeat request message can be repeatedly transmitted, and the corresponding heartbeat response message is received, that is, the above steps 72-74 can be repeatedly performed.

Step 75: After the detection period timer expires, Endpoint A determines the value of the hopping counter as the content hop.

In addition, after the hops of packets of different lengths need to be obtained, the packet loss rate of packets of different lengths can be determined, and a hopping counter is set for each packet of the padding length, and hops corresponding to different lengths are used. The variable counter determines the number of hops separately.

4 or the mode shown in Figure 5 determines the number of lost packets, and determines the number of hops in the manner shown in Figure 6.

In this embodiment, the calculation of the hopping number can be implemented by using the heartbeat request message for the communication quality detection and setting the hopping counter. In addition, the embodiment of the present invention can implement the path communication quality detection as described above after adding a heartbeat request message use field to the heartbeat request message. In addition, the heartbeat request packet of the embodiment of the present invention can be used only for the existing on-off detection. In this case, the value of the heartbeat request packet use field of the heartbeat request packet can be set to indicate that the heartbeat request packet is normal. The value of the heartbeat request message can be processed according to the existing on-off detection mode.

After obtaining the data of the above communication quality detection, different applications can be performed. For example, if the packet loss rate is greater than a certain threshold, for example, 0.1%, the sub-health status of the alternate path is presented through alarms, diaries, and the like, and the user is prompted to perform troubleshooting to ensure that the alternate path maintains a healthy communication state. When a packet of a certain length is always discarded, it is presented by a similar prompt such as an alarm, a diary, etc., to remind the user to perform a purposeful check to ensure that the alternate path maintains a healthy communication state. The alternate path communication quality detection result provides SCTP multi-homing based on the QoS handover path to provide decision data, ensuring that the SCTP multi-homing is accurate and efficient according to the QoS handover.
