[0056] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Figure 1 Schematic diagram of the system architecture of the network performance measurement method according to the embodiment of the present invention; Figure 1 As shown, the system architecture used in the network performance measurement method of this embodiment includes: a measurement control point (MCP) and at least one data collection point (DCP). The above system architecture can also be called an IP flow performance monitoring (IPFPM) architecture. In a statistical period, the difference between the number of packets entering the network and the number of packets leaving the network is the number of packet losses in the network in the statistical period; information such as latency can also be counted.

[0058] In traditional technical solutions, DCP is only used to collect data (for example, in the scenario of counting packet loss, DCP is used to count the number of received messages) and report the data to MCP; MCP collects the data reported by DCP and completes the aggregation and calculation of statistical data.

[0059] In the embodiments of the present invention, a sending device performs coloring and marking on a plurality of data packets for network performance measurement, and adds block identifiers and measurement information to the plurality of data packets; the processed plurality of data packets are sent. In this way, the sending device notifies the self-identified network performance monitoring information (such as measurement information), and the receiving device can directly obtain the added information (i.e., directly obtain the block identifier and measurement information) from the received data packet to monitor the network performance, without setting up a separate measurement information collection and matching device, and is suitable for various application scenarios, not limited to network performance monitoring scenarios in the same management domain.

[0060] An embodiment of the present invention provides a network performance measurement method, which is applied to a sending device. Figure 2 The network performance measurement method of the present invention is shown in FIG. Figure 1 ;like Figure 2 As shown, the method includes:

[0061] Step 101: marking a plurality of data packets for network performance measurement, and adding block identifiers and measurement information to the plurality of data packets;

[0062] Step 102: Send the processed multiple data messages.

[0063] In this embodiment, the sending device performs coloring on the data message to be measured for network performance, to indicate that the data message to be colored is used for network performance measurement. Exemplarily, the coloring bit in the message header of the data message can be determined in a pre-agreed manner.

[0064] The coloring bit is also called a feature identification bit. For example, the coloring bit can be divided into a packet loss coloring bit and a delay coloring bit, which are used to identify whether a service message is used for packet loss statistics or for delay statistics.

[0065] Figure 3 Schematic diagram of the structure of the Internet Protocol version 4 (IPv4) message header; Figure 3As shown in the figure, the IPv4 packet header usually includes: Version Number (Version), Header Length (Header Length), Type of Service (TOS), Total Length (Total Length), Identification (Identification), Flags (Flags), Fragmentation Offset (Fragmentation Offset), Time To Live (TTL), Protocol (Protocol), Header Checksum (Header Checksum), Source Address (Source Address), Destination Address (Destination Address), Options (Options) and Padding (Padding) and other fields.

[0066] The 3rd to 7th bits of the Type of Service (TOS) field are rarely used in actual applications. If it is confirmed that the above bits are not occupied, these bits can be used as color bits to uniquely identify service messages.

[0067] The 0th bit of the Flags field is currently still a reserved bit and can be directly used as a color bit to uniquely identify the service message.

[0068] In this way, taking the data message as an IPv4 message as an example, it can be agreed in advance which bits in the above example are used as coloring bits, and further the data message to be measured for network performance can be determined by coloring marking on the determined coloring bits.

[0069] In this embodiment, the sending device does not need to pay attention to whether network measurement is in progress, and can perform coloring marks on the coloring bits of key services. In addition, the sending device adds block identifiers (Block IDs) and measurement information to the multiple data messages, so that the receiving device can obtain the block identifiers and measurement information from the received data messages.

[0070] Reference Figure 1 The example shown is Figure 1 Taking the three DCPs in the example, if the first DCP performs color marking on the data message and adds the block identifier and the measurement information to the multiple data messages, the first DCP can be used as a sending device and the second DCP can be used as a receiving device; correspondingly, if the second DCP performs color marking on the data message and adds the block identifier and the measurement information to the multiple data messages, the second DCP can be used as a sending device and the third DCP can be used as a receiving device, and so on.

[0071] In some optional embodiments of the present invention, the block identifier and the measurement information are added to the multiple data messages, including: dividing the block identifier into multiple parts, and / or dividing the measurement information into multiple parts; adding multiple partial block identifiers and / or multiple partial measurement information to at least some of the data messages in the multiple data messages.

[0072] In some optional embodiments, the measurement information includes at least one of the following information: the duration of the dyeing cycle, the number of data packets in the previous dyeing cycle, and the timestamp of the first data packet.

[0073] In this embodiment, refer to Figure 4a As shown, the measurement information may include the TLV of the block interval, the TLV of the number of last block, and the TLV of the timestamp of the first packet; wherein the block interval can also be used to indicate the block duration, or the dyeing cycle duration; the number of the last block also indicates the number of data packets in the last dyeing cycle; the timestamp of the first data packet also indicates the timestamp of the first data packet. TLV refers to a structure consisting of a data type tag (Type), a data length (Length), and a data value (Value), and is used to describe the data type. As shown Figure 4a As shown, it includes a data type (Type) field, a data length (Length) field, and fields corresponding to a block interval (Interval of the block), the number of last blocks (number of last block), and a timestamp (Timestamp of the first packet) of the first data packet.

[0074] Reference Figure 4b As shown, it is a schematic diagram of the format of the block identifier (block ID), including a version number (Version) field, a reserved (Resv) field, a data length (Length) field, a block identifier (block ID) field, a TLV field, and a cyclic redundancy check (CRC) field, etc.

[0075] In this embodiment, the sending device divides the block identifier into multiple parts and / or divides the measurement information into multiple parts, and adds the divided partial block identifiers and / or the multiple parts of measurement information to at least some of the data messages in the multiple data messages. Figure 5aAs shown, the partial block identifiers and / or multiple partial measurement information (such as the filled area in the figure) after the measurement information and / or block identifier are divided can be added in sequence to at least part of the data messages in the multiple data messages; then the receiving device can extract the divided partial block identifiers and / or multiple partial measurement information from the received data message, combine the multiple partial block identifiers to obtain the block identifier, and / or combine the multiple partial measurement information to obtain the measurement information.

[0076] In some optional embodiments, at least one bit in each data message in the at least part of the data messages is used to carry a part of the block identifier and / or a part of the measurement information.

[0077] In this way, segmenting the block identifier and / or measurement information and adding it to the data message only takes up a small number of bits without changing the size of the existing data packet, which can effectively reduce the impact of the data packet used for network performance monitoring on other services.

[0078] In some optional embodiments of the present invention, sending the plurality of data packets with coloring marks and information added includes: periodically sending the plurality of data packets with coloring marks and information added;

[0079] The periodic sending of the multiple data packets that have been marked with colors and have information added includes: for the data packets to be subjected to network performance measurement, at specific time intervals or at specific number of packets, changing the coloring bits used for coloring marking, adding a new round of block identification and measurement information, and sending the processed data packets.

[0080] In this embodiment, the sending device periodically sends the multiple data messages with coloring marks and information added according to a preset sending cycle or coloring cycle; within a sending cycle or coloring cycle, the sending device color-marks the data messages according to the same coloring mark, and adds the segmented partial block identifiers and / or multiple partial measurement information to the data messages within the sending cycle or coloring cycle respectively; in the next sending cycle or coloring cycle, the sending device may change the coloring mark data message to color-mark, and segment the block identifier and the measurement information corresponding to the next sending cycle or coloring cycle, and add the segmented partial block identifiers and / or multiple partial measurement information to the data messages within the sending cycle or coloring cycle respectively. Among them, a sending cycle or coloring cycle can be a specific duration, or a specific number of messages.

[0081] In some optional embodiments of the present invention, the method further includes: every preset number of periods, giving up adding the block identifier and the measurement information to the data message, and adding protection information to the data message; the protection information is calculated based on the information added within a preset number of periods before the current period, and the protection information supports information recovery when the information added within the preset number of periods is erroneous.

[0082] In this embodiment, the sending device does not add block identification and measurement information in certain sending cycles or coloring cycles, but adds protection information in these sending cycles or coloring cycles; Figure 5b As shown, protection information is added to the data message at intervals of several cycles. The protection information is calculated based on the information added in a preset number of cycles before the current cycle; in this way, in the previous cycle, when a CRC check error occurs in the process of the receiving device obtaining the block identifier based on the extracted partial block identifier combination and / or obtaining the measurement information based on the extracted partial measurement information combination, the information in the corresponding cycle can be recovered according to the protection information.

[0083] Based on the above embodiments, an embodiment of the present invention further provides a network performance measurement method, which is applied to a receiving device. Figure 6 The network performance measurement method of the present invention is shown in FIG. Figure 2 ;like Figure 6 As shown, the method includes:

[0084] Step 201: receiving a plurality of data packets after coloring and information addition processing; the added information includes block identification and measurement information;

[0085] Step 202: Identify the coloring marks in the multiple data messages, and extract the block identifiers and the measurement information in the multiple data messages;

[0086] Step 203: Determine network performance information based on the measurement information.

[0087] In this embodiment, the receiving device identifies and analyzes the received data message, identifies the coloring mark in the data message, and determines that the data message is to be measured for network performance based on the coloring mark; illustratively, the receiving device can determine whether it is used for packet loss statistics or for delay statistics based on the difference in the coloring mark. In addition, the receiving device extracts the block identifiers and the measurement information from the multiple data messages; and determines the network performance information based on the measurement information.

[0088] In this embodiment, the measurement information includes at least one of the following information: the duration of the dyeing cycle, the number of data packets in the previous dyeing cycle, and the timestamp of the first data packet.

[0089] In one example, the receiving device may count the number of packets received in the previous dyeing cycle, and then determine the number of packet losses in the previous dyeing cycle based on the number of packets and the number of data packets in the previous dyeing cycle included in the measurement information in the current dyeing cycle. In another example, the receiving device may count the timestamp of the first data packet received in the current dyeing cycle, and then determine the delay of the first data packet in the current dyeing cycle based on the timestamp of the first data packet in the measurement information of the current dyeing cycle.

[0090] In some optional embodiments of the present invention, the extracting block identifiers and measurement information from the multiple data packets includes: extracting partial block identifiers and / or partial measurement information from at least some of the multiple data packets, combining the extracted partial block identifiers into block identifiers, and / or, combining the extracted partial measurement information into measurement information.

[0091] In this embodiment, the sending device adds the partial block identifiers and / or multiple partial measurement information after the measurement information and / or block identifier are divided into at least some of the data messages in sequence; the receiving device can extract the divided partial block identifiers and / or multiple partial measurement information from the received data message, combine the multiple partial block identifiers to obtain the block identifier, and / or combine the multiple partial measurement information to obtain the measurement information.

[0092] In some optional embodiments, at least one bit in each data message in the at least part of the data messages is used to carry a part of the block identifier and / or a part of the measurement information.

[0093] In this way, segmenting the block identifier and / or measurement information and adding it to the data message only takes up a small number of bits without changing the size of the existing data packet, which can effectively reduce the impact of the data packet used for network performance monitoring on other services.

[0094] In some optional embodiments of the present invention, the receiving of the plurality of data packets after being processed by coloring marks and information addition includes: receiving the plurality of data packets after being processed by coloring marks and information addition periodically;

[0095] The identifying of the coloring marks in the multiple data messages, and extracting the block identifiers and the measurement information in the multiple data messages, include: for the data messages to be subjected to network performance measurement, identifying the coloring bits for coloring marks, and extracting the block identifiers and the measurement information; if a change in the coloring bit is detected, restoring the block identifiers and measurement information of the current cycle.

[0096] In this embodiment, the sending device periodically sends the multiple data messages with coloring marks and information added according to a preset sending cycle or coloring cycle; within a sending cycle or coloring cycle, the sending device performs coloring marks on the data message according to the same coloring mark, and adds the segmented partial block identifiers and / or multiple partial measurement information to the data message within the sending cycle or coloring cycle respectively; in the next sending cycle or coloring cycle, the sending device can change the coloring mark data message for coloring mark, and segment the block identifier and the measurement information corresponding to the next sending cycle or coloring cycle, and add the segmented partial block identifiers and / or multiple partial measurement information to the data message within the sending cycle or coloring cycle respectively. Among them, a sending cycle or coloring cycle can be a specific duration or a specific number of messages. The receiving device identifies the coloring bit for coloring mark; if the coloring bit changes, it can indicate that the next sending cycle or coloring cycle has been reached, and the receiving device combines the partial block identifiers and / or partial measurement information within the current sending cycle or coloring cycle to recover the block identifiers and / or measurement information.

[0097] In some optional embodiments of the present invention, the method further includes: restoring protection information every a preset number of periods; the protection information is calculated based on information added within a preset number of periods before the current period.

[0098] In this embodiment, the sending device does not add block identification and measurement information in certain sending cycles or coloring cycles, but adds protection information in these sending cycles or coloring cycles; Figure 5b Thus, the receiving device obtains the protection information based on the information calculation in these specific periods.

[0099] In some optional embodiments of the present invention, the method further includes: if a CRC check of the extracted block identifier and / or the measurement information is erroneous within a preset number of cycles before the current cycle, the block identifier and measurement information recovered within the cycle without the check error and the protection information are calculated to recover the block identifier and / or the measurement information within the cycle with the check error.

[0100] In this embodiment, the protection information is calculated based on the information added in a preset number of cycles before the current cycle; if a CRC check error occurs in the information added in the cycle before the current cycle, it indicates that disorder or packet loss may occur. For example, the protection information is transmitted every 3 cycles. If a CRC check error occurs in the information added in one of the first three cycles, the information with the CRC check error can be restored based on the information in the two cycles without the CRC check error and the protection information. Optionally, if the information with the CRC check error cannot be restored, the receiving device abandons the current record, or considers that part of the content is available and records it after marking the error.

[0101] In some optional embodiments of the present invention, the method further includes: the receiving device sending the block identifier and the network performance information.

[0102] In this embodiment, refer to Figure 1 In the system architecture shown, the receiving device sends the block identifier and the network performance information to the MCP. The sending device side does not need to report data. The MCP counts the block identifier and network performance information reported by each receiving device (such as each DCP), and associates the network performance information corresponding to the same block identifier, so as to realize business visualization in the transmission network and facilitate fault location.

[0103] The embodiment of the present invention also provides a network performance measurement device.
