TECHNICAL FIELD The present invention relates to the field of communications technologies, and in particular, to a measurement technique.

BACKGROUND In order to meet diverse user bandwidth and quality requirements, provide higher bandwidth for multiple services, and reduce overall costs, wireless access networks are becoming more and more IP-oriented. In the process of implementing IP access in the wireless access network, the QoS (Quality of Service) control of the wireless network gradually becomes an important function.

In the IP process of the radio access network, the QoS of the wireless network depends on the IP network performance test. Currently, the end-to-end IP network performance test is performed by IPPM (IP Performance Metrics) functional entity to actively send IP performance measurement packets or perform IP performance measurement operations without service traffic. The IP performance indicators measured by the IPPM functional entity can be used as a basis for evaluating the performance of the IP network.

The current method for IP network performance testing is to measure network performance by actively transmitting data packets, and the measurement object is an active measurement message instead of a service data message. Since the measurement packet is different from the data service packet, the forwarding processing may be inconsistent in the network, which may result in a deviation between the measurement result measured by the measurement message and the real performance of the service data.

Moreover, in the current method of IP network performance testing, measurement packets are limited to UDP (User Datagram Protocol) data packets, and other protocol data packets are measured. It is still blank. For example, the method does not currently include measurement of TCP (Transport Control Protocol) data packets.

Since the current measurement method is only for measurement messages rather than service data, it cannot meet the requirements of wireless network QoS control.

DETAILED DESCRIPTION OF THE EMBODIMENTS In order to make the objects, technical solutions, and advantages of the present invention more comprehensible, the technical solutions provided by the present invention are further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The measurement information transmission method provided by an embodiment of the present invention will be described in detail below with reference to FIG. The measurement method includes:

Step 101: The source host carries the first measurement information corresponding to the measurement content in the IP packet of the service data according to the measurement content.

Step 102: Send the IP packet to the destination host.

In this embodiment, the first measurement information corresponding to the measurement content is carried into the IP packet of the service data, and the IP packet is sent to the destination host, so that the destination host can be based on the first packet carried in the IP packet. The measurement information measures the measurement content, for example, records and counts the first measurement information, and calculates an IP performance metric according to the statistical result. Since the first measurement information is carried in the IP packet of the service data, the real service data can be directly measured, thereby ensuring that the deviation between the measurement balance and the real performance of the service data is smaller and better. Full The need for wireless network QoS control. Moreover, in this embodiment, the measurement of the real service data avoids the insufficiency of only measuring the UDP protocol packet, and expands the type of the IP address to be measured. Further, since the carried first measurement information is measurement information corresponding to the measurement content, unnecessary measurement information is avoided, and bandwidth is saved while implementing flexible measurement.

Further, in this embodiment, the first measurement information needs to be carried in the IP packet of the service data, and the specific information may be carried in the header field of the IP packet, for example, the IPv4 IP packet may be carried in the header. Option (Option) field in the domain; For IPv6 IP packets, it can be carried in the option field in the extended header field, such as the Destination Options field. For the header field of the IPv4 IP packet, refer to the structure shown in FIG. 2. The header field and the extended header field of the IPv6 IP packet can refer to the structure shown in FIG.

In this embodiment, the measurement content may include, for example, one of the following or any combination thereof: delay, jitter, packet loss, packet misorder, and message repetition. The above measurement contents are merely examples, and do not limit the scope of the present invention, and may be other measurement contents.

In this embodiment, the first measurement information may include one or more measurement options, for example, may include one or any combination of the following: sequence number measurement option, transmission time measurement option, security check code option, measurement session identification option.

The sequence number measurement option is used to identify the message; the send time measurement option is used to indicate the time when the source host sends the IP packet; the security check code option is used to perform the security check; and the measurement session identification option is used to indicate that the process is in progress. Which measurement session belongs to the IP performance measurement, where the measurement session corresponds to the IP service session.

In this embodiment, different measurement contents have respective first measurement information.

For example, when the measurement content includes a time delay, the first measurement information includes at least: a transmission time measurement option and a sequence number measurement option. For example, when the measurement content includes jitter, the first measurement information includes at least: a transmission time measurement option and a sequence number measurement option. For example, when the measurement content includes packet loss, the first measurement information includes at least: a sequence number measurement option. For example, in measurement When the content includes the wrong sequence of the message, the first measurement information includes at least: a sequence number measurement option. For example, when the measurement content includes the message repetition, the first measurement information includes at least: a sequence number measurement option.

When the measurement content includes a combination of a plurality of contents, the first measurement information corresponding to the measurement content does not contain repeated measurement options. For example, the measurement content includes jitter and packet loss, and the first measurement information corresponding to the measurement content includes at least: a sequence number measurement option and a transmission time measurement option, and does not include a repeated sequence number measurement option.

In addition, regardless of the specific content included in the measurement content, the first measurement information corresponding to the measurement content may further include a measurement session identification option and/or a security check code option.

In this embodiment, when the security check code option is included in the first measurement information, the destination host may perform security check after receiving the IP packet, thereby discriminating the forged measurement packet, and ensuring accurate measurement. Safety. When the measurement information identifier is included in the first measurement information, the destination host can perform statistics according to different measurement sessions, so that different measurement sessions can be separately measured, and measurement results of each measurement session are obtained, thereby obtaining each IP service. The IP performance metrics of the session make the measurement results more accurate and the measurement method more flexible.

In this embodiment, when the first measurement information is carried in the IP packet of the service data, there is a difference between the IPv4 and IPv6 IP documents.

In order to carry the measurement information in the IP packet of the service data, the embodiment of the present invention extends the existing IPv4 protocol and the IPv6 protocol, and adds measurement options, such as a transmission time measurement option, a reception time measurement option, and a sequence number measurement. Options, measurement session identification options, security check code options. According to the IPv4 or IPv6 protocol format, the option consists of three parts: Option Type, option length, and option content. In order to distinguish it from other options, for these new measurement options, an option type different from the other options is required, and the option type of the above measurement option is defined as, for end-to-end IP performance measurement, and the IP device of the intermediate node cannot Delete or modify the contents of these end-to-end measurement options.

For example, in an IPv4 message, the option type can be represented by 8 bits, where 1 bit represents a copy flag, and 2 bits represent an option class, a 5-bit table. Show option number ( option number ). The option category of the above measurement options can be 2 (2 means for debugging and measurement), and the option number for sending time measurement option, receiving time measurement option, sequence number measurement option, measurement session identification option, security check code option can be separately For 5, 6, 7, 8, and 9.

For example, in an IPv6 message, the option type can also be represented by 8 bits, and the highest 2 bits of the option type of the above measurement option are defined as "00", so that the IP device capable of supporting the option type can be recognized by the option, IP devices that support this option type ignore this option and avoid exception handling that occurs because the IP device cannot support this option. For example, the options for the send time measurement option, the receive time measurement option, the sequence number measurement option, the measurement session identification option, and the security check code option can be 11, 12, 13, 14, and 15, respectively.

In this embodiment, the source host and the destination host need to dynamically adjust the MTU saved in the measurement process because the source host and the destination host add measurement options to the IP packet to change the IP packet length of the service data. Transmission Unit, minimum transmission unit) value.

Further, in the embodiment, the first measurement information may also be compressed. When the first measurement information is compressed, it may be a compression option field or an entire header field. By compressing, the bandwidth occupied by IP packets can be reduced, and the transmission can be smooth.

In this embodiment, the compression of the first measurement information may only compress a portion of the first measurement information, such as only the transmission time measurement option and/or the sequence number measurement option, without compressing the security check code option and/or measurement. Session identification options.

In this embodiment, the above compression method may be, for example, the method shown in FIG. 4:

Step 401: Initialize the context of the measurement information in the first IP packet with the measurement information, where the measurement information used for initialization may be a configuration agreed by the source host and the destination host.

Step 402: Receive a feedback response sent by the destination host, where the feedback response is sent after the destination host determines the context of the measurement information according to the first IP with the measurement information.

Step 403, according to the change of the measurement information to be sent and the context of the initialized measurement information, In the TP packet of the subsequent service data, the change value of the transmission time measurement option, the reception time measurement option, the sequence number measurement option, and the like are carried, thereby saving bandwidth.

After receiving the IP packet of the service data, the destination host can learn the specific content of each measurement option included in the measurement information according to the measurement information context and the change value, that is, decompress, and record according to the decompressed measurement option. Statistics, and finally calculate the IP performance metric.

Further, in this embodiment, the step of acquiring the measurement configuration may be included, for example, the measurement configuration configured in the source host itself may be obtained, or the measurement configuration sent by the network management system may be acquired. After the measurement configuration is obtained, further, the embodiment may further include the step of negotiating the measurement configuration with the destination host according to the obtained measurement configuration.

Specifically, the measurement configuration may be obtained by the static configuration of the source host and the destination host, or may be implemented by the network management remote operation, that is, the network management system sends the measurement configuration to the source host and the destination host. . The destination host obtains the measurement configuration, and the source host negotiates the measurement configuration with the destination host after obtaining the measurement configuration. The measurement configuration negotiation may be a source host and a destination host, or a measurement proxy node of the source host and the destination host, or a measurement proxy node and a destination host of the source host, or a measurement proxy node and a destination host of the source host. Measure the proxy node. In this embodiment and the following embodiments, the measurement negotiation between the source host and the destination host is taken as an example. And it can be considered that the negotiation of the measurement configuration with the measurement proxy node is basically the same as the negotiation of the measurement configuration between the source host and the destination host, and the measurement proxy node and the source host or the destination host may be in one entity, or Implemented as two entities.

Wherein, the above measurement configuration may include, for example, measurement content. The measurement configuration may further include one or any combination of the following in addition to the above: an initial value of the sequence number measurement option, a transmission interval of the measurement information, a measurement period, an effective waiting delay, a measurement verification algorithm, a key, Measurement start time, measurement type, compression indication, measurement session identification, measurement direction, source host address, destination host address.

The initial value of the sequence number measurement option is used to represent the first IP message with measurement information. The value of the sequence number measurement option. The sending interval of the measurement information is used to indicate the length of the sending interval between two IP packets with adjacent sequence numbers, that is, the source host is sent the next band after sending an IP packet with measurement information. The approximate time of the IP packet with the measurement information (because the exact time depends on the time when the IP service session generates the service data IP packet), the transmission interval of the measurement information can also be expressed as the transmission frequency of the measurement information. The measurement period is used to indicate the duration of the current measurement. The measurement content is the content that needs to be measured for this measurement, that is, the packet loss, jitter, and message misordering mentioned above. The effective waiting delay is used to indicate that when the destination host receives an IP packet whose delay exceeds the value, the delay of the IP packet should be recorded as infinity, that is, the packet is considered to be lost in performance measurement. The measurement check algorithm is used to represent the algorithm used to perform the verification, such as the algorithm used for security check or redundancy check. The key is used to indicate the key used to calculate the check code. It may be that the specific key content is sent, or the source host and the destination host both retain the key list, and the index of the sent key list is not sent. Key content, in this embodiment, the check code includes a security check code. The measurement start time is used to indicate the approximate time that the source host sends the first IP packet with measurement information to the destination host (because the exact time depends on the time when the IP service session generates the service data IP packet). The measurement type is used to indicate whether the measurement is an active measurement or a passive measurement. The active measurement is a measurement of a special measurement message (an IP packet dedicated to IP performance measurement) rather than an IP packet for service data. The measurement is performed, and the passive measurement is to measure the IP packet of the service data, instead of measuring the special measurement message. The compression indication is used to indicate that the measurement information in the message is compressed and needs to be decompressed. The measurement direction is used to indicate that the measurement is a one-way measurement or a two-way measurement. The one-way measurement is the measurement of delay, jitter, packet loss, packet misordering, and message repetition in a single direction from the source host to the destination host. The two-way measurement is the measurement of the delay, jitter, packet loss, packet misorder, and packet repetition in the two directions of the source host to the destination host and then back to the source host.

In this embodiment, the method for negotiating the measurement configuration may be, for example, the method shown in FIG. Methods for negotiating configuration configurations include:

Step 501: Generate a measurement negotiation request according to the obtained measurement configuration, where the measurement negotiation is requested. The request includes a measurement configuration.

Step 502: Send the measurement negotiation request to the destination host, where the destination host sends a measurement response message to the source host after receiving the measurement negotiation request, when it can accept and is willing to accept the IP performance measurement; When it is unable or unwilling to accept the IP performance test, a rejection response message is sent to the source host.

Step 503: Receive a negotiation response message or a rejection response message sent by the destination host to receive the measurement.

Through the measurement negotiation process, the measurement configuration of the source host and the destination host can be clarified, and the parameters of the current measurement, such as the measurement content to be measured, for the active measurement or the passive measurement, and the sequence number measurement option are determined by the measurement configuration. Initial value, etc. In addition, the measurement verification algorithm and the used key can be negotiated, and the measurement information can be negotiated to ensure that the measurement is flexible and consistent with both configurations. In addition, the source and destination hosts need to adjust their saved MTU values after the measurement negotiation is completed, that is, use the original MTU value minus the total length of various measurement options that may be used.

Further, the measurement method provided in this embodiment may further include the steps as shown in FIG. 6. Step 601: Receive a measurement response sent by the destination host, where the measurement response message is sent by the source host to the destination host. The IP packet carrying the service data of the first measurement information, and carrying the second measurement information corresponding to the IP packet.

The destination host receives the IP packet of the service data carrying the first measurement information sent by the source host. The destination host records the measurement options included in the first measurement information according to the first measurement information carried in the received IP packet, and performs statistics on the recorded result, and calculates the IP performance metric value by statistical aggregation, that is, according to the first The measurement information measures the received IP packet.

When the measurement direction included in the measurement configuration is bidirectional, the destination host sends a measurement response packet based on the IP packet to the source host. The measurement response packet can be a service data packet or a separate IP packet. The measurement response message includes second measurement information corresponding to the IP packet received by the destination host. The second measurement information includes the first measurement in the IP packet received by the destination host. Part or all of the information, and when the first measurement information includes a transmission time measurement option, the second measurement information further includes a reception time measurement option. When the measurement direction included in the measurement configuration is bidirectional measurement, and the measurement content includes delay and/or jitter, the second measurement information carried in the measurement response message may include a reception time measurement option; and when the measurement content includes delay and The first measurement information carried in the IP packet of the service data sent by the source host also includes the transmission time measurement option. Therefore, it can be said that the first measurement information of the IP packet sent by the source host includes the transmission time. When the option is measured, the second measurement information also includes a reception time measurement option. In the embodiments of the present invention, the receiving time measurement option is used to indicate the time when the destination host receives the IP packet.

In this embodiment, if the first measurement information in the received IP packet includes only one or more of a sequence number measurement option, a transmission time measurement option, and a measurement session identification option, the second measurement information includes the first Measure all of the information, and when the first measurement information includes a transmission time measurement option, the second measurement information further includes a reception time measurement option; when the first measurement information includes a security check code option, the second measurement information includes the first The portion of the measurement information, that is, does not include the security check code option in the first measurement information, but includes a new security check code option.

For example, if the first measurement information in the IP packet received by the destination host only includes the sequence number measurement option, the second measurement information in the measurement response includes the same sequence number measurement option. By carrying the same sequence number measurement option in the measurement response message, you can measure two-way packet loss, packet misordering, and message repetition. If the first measurement information in the IP packet received by the host includes the sequence number measurement option and the transmission time measurement option, the second measurement information in the measurement response includes the same sequence number measurement option and is sent. The time measurement option, and also includes the receiving time measurement option of the destination host. By carrying the same sequence number measurement option, transmission time measurement option, and reception time measurement option in the measurement response message, two-way delay and jitter can be measured, and two-way packet loss, packet misorder, and message can be simultaneously measured. repeat.

In this embodiment, the second measurement information may further include a security check code option and a measurement session identification option. The security check code option in the second measurement information is usually different from the security check code option carried in the received IP 4 message, and the measurement session identification option and the received IP packet are carried. The measurement session identification options are the same.

After the destination host sends the measurement response packet, the source host receives the measurement response packet. Step 602: Extract the second measurement information from the measurement response message.

Step 603: Perform recording statistics according to the second measurement information.

Recording statistics are performed according to the measurement options included in the second measurement information, and the IP performance metric value is calculated according to the statistical result to know the bidirectional IP performance.

In this embodiment, when the source host or the destination host receives the IP packet or the IP packet of the data service, for example, the IP packet is fragmented during the transmission process, and the IP packet is received. After that, the received IP packet needs to be reorganized and restored to the original IP packet, that is, the originally sent packet, and then processed.

In this embodiment, when the source host or the destination host includes the compression indication in the measurement configuration, the compression step as shown in FIG. 4 needs to be performed before the IP packet or the measurement response packet is sent, and Decompression is required before making measurements based on measurement information.

In this embodiment, whether the source host or the destination host includes the measurement verification algorithm in the measurement configuration, the received IP packet needs to be verified. After the verification is passed, the next step is processed.

It should be noted that there is no fixed order for performing verification or decompression. For example, the decompression may be performed after verification, or may be decompressed and then verified.

With this embodiment, the packet protocol type of the IP performance test can be extended, so that the type of the tested IP packet protocol is not limited to the UDP protocol, and may include other protocols, such as the TCP protocol. Moreover, since the IP packet of the service data is directly measured, the measurement score is more accurate, and the difference between the real performance of the service data is smaller, and the QoS control requirement can be better satisfied. Moreover, various measurement contents can be measured, and only the measurement content corresponding to the content to be measured is carried as needed, and the bandwidth is effectively utilized. In this embodiment, by compressing the measurement information, the bandwidth occupation can be further reduced, and the security of the message can be ensured by carrying the security check code, and the spoofed message can be discriminated. By measuring the configuration negotiation, both parties can flexibly configure various parameters, and And a good understanding of the other party's configuration, to achieve the agreement between the two sides. By carrying the measurement session identification option, specific measurements can be made for a certain data service, making the measurement more flexible, more targeted, and the result closer to the true performance of the business data.

A method of measurement provided by another embodiment of the present invention will be described below with reference to FIG. This embodiment is a specific description of the previous embodiment. The method includes:

Step 701: Obtain a measurement configuration sent by the network management.

The NMS performs remote operations on the source host and sends the measurement configuration to the source host. The measurement configuration includes: initial value of sequence number measurement option, transmission interval of measurement information, measurement period, measurement content, effective waiting delay, security check algorithm, key, measurement start time, measurement type, compression indication, measurement Session ID, measurement direction, source host address, destination host address.

The initial value of the IP packet sequence number measurement option is 0; the measurement interval is 5 seconds; the measurement period is 30 minutes; the measurement content is delay and the message is out of order; the effective waiting delay is 3 seconds. The security check algorithm is a key spalling algorithm; the key is 0xDlD83946; the measurement start time is 19:30 minutes, 10 seconds, 30 milliseconds on August 09, 2009; the measurement type is passive measurement; the compression indication is uncompressed; The measurement session identifier is 0x1200 for representing the ongoing IP telephony service of the host (using the UDP protocol), and 0x1201 is for representing the ongoing IP Internet service of the host (using the TCP protocol); the measurement direction is bidirectional.

Step 702: Generate a measurement negotiation request according to the obtained measurement configuration, and send the measurement negotiation request to the destination host.

The source host generates a measurement negotiation request according to the measurement configuration, and the negotiation measurement request includes the foregoing measurement configuration.

After receiving the measurement negotiation request sent by the source host, the destination host sends a negotiation response message that accepts the measurement if it is willing and able to perform IP performance measurement with the source host; if it is unwilling or unable to perform measurement with the source host IP performance, the rejection is sent. Response message. The measurement configuration is also included in the negotiation response message that accepts the measurement. In this step, the received negotiation response message receiving the measurement includes: an initial value of the sequence number measurement option, a transmission interval of the measurement information, a measurement period, Measurement content, effective wait delay, security check algorithm, key, measurement start time, measurement type, compression indication, measurement session identification, measurement direction, source host address, destination host address.

Step 703: Receive a negotiation response message that is sent by the destination host and receives the measurement.

After receiving the negotiation response message sent by the destination host, the source host and the destination host complete the negotiation process.

Step 704: Carry the first measurement information corresponding to the measurement content in an option field of the header field of the IP packet of the service data.

In this embodiment, an IPv4 packet is taken as an example. In the measurement configuration determined in the above steps, the measurement content includes delay and message misordering. For the delay, the corresponding first measurement information includes at least: a sending time measurement option and a sequence number measurement option; and for the grammatical error sequence, the corresponding first measurement information includes at least: a sequence number measurement option. In order to ensure the security of the text, the first measurement information also includes a security check code option. And in order to obtain the measurement result of each service more flexibly and accurately, the first measurement information further includes a measurement session identification option.

For example, in the first IP packet carrying the first measurement information, the transmission time measurement option is 19:30:10, 30 milliseconds on August 09, 2009, and the sequence number measurement option is 0, security check code option. For 0xDlD56896, the measurement session identification option is 0x1201.

The above measurement option is carried in the option field of the header field of the IP packet of the service data. And the option type for each measurement option uses the value of the option type specified in advance.

Step 705: Send the IP packet to the destination host.

During the delivery process, the IP packet may be fragmented.

If the IP packet is fragmented during the transmission process, the destination host needs to reassemble and revert to the original IP packet, that is, the IP packet sent by the source host.

The destination host performs security check on the original IP packet, and after performing the check, it performs measurement according to the first measurement information carried in the IP packet, and obtains a delay and a packet error from the source host to the destination host in one direction. In order, the unidirectional IP performance metric of the IP Internet service is obtained.

Since the measurement direction in the measurement configuration is bidirectional, the destination host generates a measurement response message. And the measurement response packet carries the second measurement information corresponding to the received IP packet. The second measurement information includes: a transmission time measurement option, a sequence number measurement option, a reception time measurement option, a security check code option, and a measurement session identification option. Among them, the transmission time measurement option is 19:30:10, 30 milliseconds on August 09, 2009, the sequence number measurement option is 0, and the reception time measurement option is 19:30:10, 50 milliseconds on August 09, 2009, security The checksum option is 0xDlD48962 and the measurement session identification option is 0x1201.

The destination host sends the generated measurement response to the source host.

Step 706: Receive a measurement response sent by the destination host, where the measurement response carries the second measurement information.

Step 707: Extract the second measurement information from the measurement response message, and record the time when the measurement response message is received. For example, the measurement response message receiving time is 19:30:10 on August 09, 2009. 80 milliseconds in seconds.

Before the second measurement information is extracted, if the measurement response message has been fragmented in the transmission, the measurement response message needs to be reorganized and restored to the original IP packet, that is, the measurement response originally sent by the destination host. Text.

After the original IP packet is restored, the original packet is also checked for security. If the security check is performed, the second measurement information carried in the measurement response packet is extracted.
