Description

Time delay data measuring method, device, system, electronic equipment and storage medium
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, a system, an electronic device, and a storage medium for measuring delay data.
Background
A PON (Passive Optical Networks) is a system for providing network access between the edge of a service provider's network and the end consumer. In the PON system, the upstream and downstream delay asymmetry is obvious. The uplink delay is usually large because TDMA (Time division multiple access) and DBA (Dynamic Bandwidth Allocation) scheduling exists in the uplink and the downlink is broadcast. Therefore, half of the RTT (Round-Trip Time) cannot be used instead of the one-way delay.
In the conventional measurement of one-way delay, clock synchronization devices such as CDMA (Code Division Multiple Access) and GPS (Global Positioning System) are usually required to be externally hung, so as to improve the accuracy of delay measurement, and the additional addition of the clock synchronization devices on the devices undoubtedly increases the cost of the devices, and meanwhile, the efficiency of one-way delay measurement cannot meet the actual requirements.
Therefore, how to improve the efficiency of delay measurement becomes a technical problem which needs to be solved urgently.

Fig. 1 shows a schematic diagram of an exemplary system architecture of a delay data measuring method or a delay data measuring apparatus that can be applied to the embodiments of the present disclosure.
Fig. 1 is a schematic diagram of a PON 100 system. The PON 100 includes an OLT (Optical Line Terminal) 110, a plurality of ONUs (Optical Network units) 120, and an ODN (Optical Distribution Network) 130 that couples the OLT 110 and the ONUs 120. The PON 100 is a communication network that does not require any active components to distribute data between the OLT 110 and the ONUs 120. Instead, the PON 100 uses passive optical components in the ODN 130 to distribute data between the OLT 110 and the ONUs 120. The PON 100 may be configured to operate in accordance with ITU-T based protocols. For example, PON 100 may employ messages as described in ITU-T Recommendations G.9807.1 and/or G.989.3. The PON 100 serves as an access network and is designed to serve as the last mile connection between an end user and the internet. Further, the PON 100 is configured such that a signal from the OLT 110 is transmitted to all ONUs 120. Specifically, the OLT 110 assigns each ONU 120 a downstream time slot and/or channel, and the ONUs 120 read the data received at their respective time slots. In addition, the OLT 110 allocates upstream time slots and/or channels so that each ONU 120 can transmit upstream data in a manner that does not interfere with data from other ONUs 120.
The OLT 110 is an optical device configured to transmit data downstream from a core network (e.g., the internet) towards the ONUs 120 and upstream from the ONUs 120 towards the core network. Specifically, the OLT 110 acts as an intermediary between the core network and the ONUs 120. The OLT 110 may be located at a central location, such as a central office, but may be located at other locations as well. The OLT 110 typically contains one or more transmitters, receivers, and/or transceivers, collectively referred to as transceivers for clarity, configured as an upstream interface for communicating with the core network.
The OLT 110 also typically contains one or more downstream transceivers configured as downstream interfaces for communicating with the ONUs 120. In a multi-channel implementation, different interfaces communicate over different channels. For example, a first interface may communicate over a first channel, a second interface may communicate over a second channel, and so on. As used herein, a channel is a bounded set of wavelengths (or frequencies). Thus, different channels operate at different wavelengths and corresponding frequencies. Such an interface may be employed by the OLT 110 to modulate multiple wavelength signals onto a single optical carrier, which generates an optical signal containing multiple data signals at different wavelengths/frequencies.
The ODN 130 is a data distribution system. The ODN 130 may include fiber optic cables, couplers, splitters, distributors, and/or other equipment for conveying optical signals between the OLT 110 and the ONUs 120. Such fiber optic cables, couplers, splitters, distributors, and/or other equipment are passive optical components. In particular, fiber optic cables, couplers, splitters, distributors, and/or other equipment are components that do not require any power to distribute data signals between the OLT 110 and the ONUs 120. Accordingly, the ODN 130 propagates optical signals between the OLT 110 and the ONUs 120 without making changes to these signals (e.g., without exchanging packets).
In some cases, the ODN 130 may include some active components, such as optical amplifiers, to maintain signal quality and/or reduce signal loss. The ODN 130 may extend from the OLT 110 to the ONUs 120 in a branching configuration as shown in fig. 1, but may also be configured in any other point-to-multipoint configuration.
The ONUs 120 are devices configured to transmit data between the OLT 110 and a customer or user. In particular, the ONUs 120 may act as an intermediary between the OLT 110 and the customer. For example, the ONUs 120 may receive data from the OLT 110 via an upstream interface and forward such data to a customer via a downstream interface, or vice versa. For example, the ONU 120 may include one or more upstream interfaces, each including an optical transceiver (e.g., an optical transmitter and an optical receiver) configured to couple to the ODN 130.
The ONU 120 also includes one or more downstream interfaces, such as ethernet ports, for communicating with a local network, such as a home or office network. In addition, the ONUs 120 may include converters that convert optical signals received from the OLT 110 into electrical signals for the customer, such as signals in an ethernet or Asynchronous Transfer Mode (ATM) protocol. In examples employing multiple channels, the ONU 120 may comprise multiple upstream interfaces for transmitting and receiving optical signal data in the corresponding channels.
As described above, the OLT 110 and the ONUs 120 can increase the peak data rate by logically combining multiple channel-specific interfaces into a single logical link using channel bonding for the purpose of both Open Systems Interconnection (OSI) model layer two types of communication. For example, the OLT 110 may bundle multiple downstream interfaces into a logical link. The OLT 110 may then divide SDUs (Service Data units), such as ethernet frames, from the core network into a plurality of blocks and send the blocks simultaneously over a plurality of downstream interfaces and thus over a plurality of channels. In this manner, SDU blocks are transmitted in parallel rather than serially across the ODN 130. ONU 120 may receive these blocks via multiple upstream interfaces and may order the received blocks to reconstruct SDUs. The same procedure can also occur for upstream communication. For example, SDUs from the local network (e.g., from a user) may be split into multiple chunks and forwarded across multiple upstream interfaces at the ONU 120. The OLT 110 may receive these blocks by means of multiple downstream interfaces and may reconstruct SDUs for transmission towards the core network.
The present exemplary embodiment will be described in detail below with reference to the drawings and examples.
First, the embodiments of the present disclosure provide a time delay data measurement method, which may be applied to a first device or executed by any electronic device with computing processing capability.
Fig. 2 shows a flowchart of a method for measuring delay data in an embodiment of the present disclosure, and as shown in fig. 2, the method for measuring delay data in the embodiment of the present disclosure includes the following steps:
s202, receiving a first datagram sent by second equipment, wherein the first datagram comprises first timestamp information and a first identifier, the first timestamp information is time information when the second equipment sends the first datagram, and the first identifier is used for marking business information to which the first datagram belongs;
it should be noted that the first datagram may be an IP (Internet Protocol) datagram, and the IP datagram is a packet transmitted on the Internet defined by a TCP (Transmission Control Protocol)/IP Protocol, and is composed of a header and a data portion. The first part of the header is a fixed length, 20 bytes in total, that all IP datagrams must have. Following the fixed part of the header are some optional fields, the length of which is variable; the source and destination addresses in the header are both IP protocol addresses. Referring to a datagram format diagram shown in fig. 3, the formats of various datagrams mentioned in the embodiments of the present disclosure may be as shown in fig. 3.
In one embodiment of the present disclosure, when measuring the uplink time delay, the first device may be a olt device, and the second device may be a onu device; when measuring the downstream delay, the first device may be a onu device and the second device may be a olt device.
And S204, determining to acquire first time delay data of the service corresponding to the first datagram according to the first timestamp information, the first identifier and first receiving time information, wherein the first receiving time information is time information when the first device receives the first datagram.
It should be noted that, after receiving the first datagram, the first device extracts first timestamp information and a first identifier included in the first datagram, and records time information of a local clock when receiving the first datagram; taking the time value of the local clock when the first equipment receives the first data telegram as first receiving time information; calculating a first one-way time delay for receiving the first datagram according to the first timestamp information and the first receiving time information, wherein the first one-way time delay can be a difference value between two time values of the first receiving time information and the first timestamp information; the first device determines the service to which the first datagram belongs according to the first identifier, and records and obtains first time delay data of the service corresponding to the first datagram, where the time delay data may include information such as an IP quintuple of the first datagram, the first identifier, first timestamp information, and one-way time delay.
In one embodiment of the present disclosure, the format of the latency data may be as shown in table 1 below;
TABLE 1
Figure BDA0003759369980000101
In an embodiment of the present disclosure, the first device may further report the obtained unidirectional delay data to the statistical device at a preset period, where the statistical device is configured to receive unidirectional delay data uploaded by other devices, and determine, based on the unidirectional delay data and the identifier, an uplink or downlink unidirectional delay of the corresponding service.
According to the method for measuring the time delay data, the first time delay data of the service corresponding to the first datagram is determined to be obtained according to the first timestamp information and the first identification contained in the first datagram and the first receiving time information when the first datagram is received by receiving the first datagram sent by the second device, so that the efficiency and the precision of time delay data measurement are improved, and meanwhile, the cost of the measured device is reduced.
In addition, the time delay data measurement method disclosed by the disclosure can be applied to the PON system disclosed in fig. 1, and an external clock synchronization device is not required by using the clock synchronization function of the PON system; the identification of the head part in the datagram can also be used for associating the time delay data with the specific service packet, so that the time delay data of the service layer is provided, and the service party can position the corresponding service based on the time delay data.
In an embodiment of the present disclosure, determining to acquire first delay data of a service corresponding to a first datagram according to first timestamp information, a first identifier, and first receiving time information may be implemented by the steps disclosed in fig. 4, and referring to another flow chart of a delay data measuring method shown in fig. 4, the method may include the following steps:
s402, acquiring first receiving time information when a first data report is received;
s404, determining a first one-way time delay for obtaining the first datagram according to the first timestamp information and the first receiving time information;
s406, determining to obtain first time delay data of the service corresponding to the first datagram according to the first unidirectional time delay and the first identifier.
It should be noted that, a time value of the local clock when the first device receives the first datagram is used as the first receiving time information; calculating the difference value between the time value in the first timestamp information and the time value in the first receiving time information to obtain a first one-way time delay; and determining the service corresponding to the first datagram according to the first identifier, associating the first one-way delay with the service corresponding to the first datagram, and determining to obtain first delay data of the service corresponding to the first datagram. Here, the device identifier of the second device, the IP quintuple of the first datagram, the first identifier, the first timestamp information, the delay direction, and other information may also be written into the first delay data.
In an embodiment of the present disclosure, the method may further include the steps disclosed in fig. 5, referring to another flowchart of the time delay data measurement method shown in fig. 5, and the method may include the following steps:
s502, receiving a plurality of fragmented datagrams sent by a second device, where the plurality of fragmented datagrams include a second datagram and a third datagram, the second datagram is a first datagram in the plurality of fragmented datagrams sent by the second device to the first device, the third datagram is a last datagram in the plurality of fragmented datagrams sent by the second device to the first device, and the second datagram includes second timestamp information and a second identifier.
And S504, determining to acquire second time delay data of the services corresponding to the plurality of fragmented datagrams according to the second timestamp information, the second identifier and third receiving time information, wherein the third receiving time information is time information when the first device receives the third datagram.
It should be noted that, the plurality of fragmentation datagrams, the second datagram and the third datagram may all be IP datagrams, which satisfy the format of the IP datagram. During sending a datagram to the first device, the second device may determine whether the datagram exceeds a Maximum Transmission Unit (MTU) limit, where the MTU limit of the ethernet is usually 1500 bytes, and fragment processing is performed on data exceeding 1500 bytes. And under the condition that the datagram exceeds the MTU limit, the second equipment fragments the datagram to obtain a plurality of fragmented datagrams, and then sends the fragmented datagrams to the first equipment. Here, the identifiers contained in the headers of the fragmented datagrams are all the same, but the slice offsets of the headers are different, and the message transmission order in which the second device transmits the fragmented datagrams can be marked by a "flag" bit. In the process of receiving a plurality of fragment datagrams, when it is recognized that the identifiers in the currently received fragment datagram and the last received fragment datagram are the same, the first device does not calculate the one-way delay any longer, determines the last fragment datagram arriving at the first device based on the identifiers, and uses the difference between the timestamp information in the first fragment datagram and the time information when the last fragment datagram arrives as the one-way delay corresponding to the identifiers, that is, obtains the one-way delays of the plurality of fragment datagrams.
