Detailed Description

Embodiments of the present application are described below with reference to the accompanying drawings.

The terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely illustrative of the manner in which embodiments of the application have been described in connection with the description of the objects having the same attributes. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Referring to fig. 1-1, a schematic diagram of a system architecture according to an embodiment of the present application is shown, where the system architecture includes a communication network system 100, a first user device 200 and a second user device 300, the communication network system 100 includes a plurality of network devices, and a message may be transmitted between the first user device 200 and the second user device 300 through the network devices in the communication network system 100.

In some possible implementations, the first user device 200 or the second user device 300 may be a terminal device or a server. In some possible implementations, the first user device 200 or the second user device 300 may be a physical device or a virtual device, and the first user device 200 or the second user device 300 may also be a container instance. The first user device 200 and the second user device 300 may be the same type of communication device (terminal device or server, entity device or virtual device or container instance) or may be different communication devices.

The terminal device may be referred to as a terminal (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like. The terminal device may be a mobile phone, a tablet (pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), etc. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the terminal equipment.

The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, basic cloud computing services such as big data and an artificial intelligent platform.

Since a server needs to respond to a service request and process the service, and provide a reliable service, in general, the server should have a capability of bearing the service and guaranteeing the service, and the server needs to have a strong processing capability, high stability, high reliability, high security, expandability, and manageability. In an embodiment of the present application, the server may be an x86 server, which is also called a complex instruction set computer (complex instruction set computer, CISC) architecture server, i.e., a so-called personal computer (personal computer, PC) server, which is a server based on a PC architecture using Intel (Intel) or other processor chips compatible with the x86 instruction set and a windows operating system.

For example, referring to fig. 1-2, the communication network system 100 may include M network devices (M is a positive integer) for forwarding messages between the first ue 200 and the second ue 300. Illustratively, the plurality of network devices includes network devices 102-107 (i.e., network device 102, network device 103, network device 104, network device 105, network device 106, network device 107). A message forwarding path may be determined based on a flow direction of the message, the message forwarding path may include an ingress (ingress) network device, an egress (egress) network device, and optionally, at least one transit (transit) network device located between the ingress network device and the egress network device.

1-2, in the example where the first user device 200 transmits a message to the second user device 300 through the communication network system 100, if the message forwarding path is network device 102- > network device 103- > network device 104- > network device 107, then the network device 102 is an ingress network device, the network device 102 and the network device 103 are transit network devices, and the network device 107 is an egress network device. The two network devices shown in fig. 1-2 may be connected in direct communication or may be connected in communication via the internet.

Each of the network devices 102 to 107 may be a device for forwarding a message in the communication network system 100, such as a switch (virtual switch or physical switch) or a router (virtual router or physical router). Network devices 102-107 may be the same type of network device, e.g., network devices 102-107 may each be a router. Alternatively, network devices 102-107 may be different types of network devices, for example, some of network devices 102-107 may be routers and some may be switches, without limitation.

The router is a hardware device connected with two or more user devices, and plays a role of a gateway between the user devices, and the router is a special intelligent network device capable of reading a destination address in a message and deciding how to transmit the message according to the destination address; the router can understand different protocols, such as an Ethernet protocol used by a local area network, a transmission control protocol/interconnection protocol (Transmission Control Protocol/Internet Protocol, TCP/IP) protocol used by the Internet, and the like, so that the router can analyze destination addresses of messages transmitted by various different types of networks and convert non-TCP/IP addresses into TCP/IP addresses, or vice versa; the router then transmits each message to the destination address according to the optimal transmission path according to the routing algorithm, so that the router can connect the non-TCP/IP network to the Internet.

It should be noted that the system architectures shown in fig. 1-1 and fig. 1-2 above are merely for illustration, and are not intended to limit the technical solutions of the embodiments of the present application, and in the specific implementation process, the communication network system 100 may further include other devices, and the number of network devices may be configured as needed.

Many application scenarios (e.g. ultra-reliable low-latency communications for fifth generation mobile communication technologies, industrial internet, intelligent factories, etc.) have clear requirements for the reliability of network transmissions, requiring the network to guarantee that traffic end-to-end does not drop packets with very high probability (e.g. 99.99% or even higher), but double (multiple) transmission options may lead to message misordering. Message disorder is a common phenomenon in a network, and causes a problem in processing a message by a receiving end, for example, misjudgment of packet loss is caused.

As shown in fig. 1-3, which is an example of dual transmission and reception, a flow of messages enters the network through the network device 102, and the messages are sent through a first message forwarding path and a second message forwarding path, respectively. The first packet forwarding path is network device 102- > network device 103- > network device 104- > network device 107, and the second packet forwarding path is network device 102- > network device 105- > network device 106- > network device 107, and finally, the first packet forwarding path leaves the network through network device 107.

Under dual transmission and reception, the network device 102 copies each received message and marks the same message sequence number. And then, sending out the two messages with the same message sequence numbers through the first message forwarding path and the second message forwarding path respectively. After the network device 107 receives the same message, it performs a selecting operation, in which one message that arrives first is sent and another message that arrives after being discarded. The transmission delay between different message forwarding paths is different, and the delay of the message on the forwarded network equipment is jittery, so that the message may be disordered once the packet loss occurs on a certain message forwarding path.

1-3, when network device 107 receives message 0/1/2 sent by first user device 200, message 0/1/2 is sent to network device 103 (first message forwarding path) and network device 105 (first message forwarding path), respectively. The message sent to the network device 103 is again denoted as 0a/1a/2a and the message sent to the network device 105 is denoted as 0b/1b/2b. Then, if the packet 0a arrives at the network device 107 before the packet 0b, the packet 0b is received by the network device 107 and then discarded, and the packet 1b is discarded in the second packet forwarding path before arriving at the network device 107, and a larger delay is experienced in the first packet forwarding path before the packet 1a arrives at the network device 107. Message 2b experiences less delay in the second message forwarding path before reaching network device 107, before message 1a arrives. If the network device 107 only performs the selective receiving without any other processing, the message is out of order, i.e. the network device 107 sends the message 0/2/1 to the second user device 300 in sequence.

In addition, load balancing is commonly used to improve the network bandwidth utilization, that is, when one or more packet forwarding paths are provided, the packet forwarding paths can be used for transmission at the same time according to a certain rule.

1-4, the network device 102 extracts flow information (e.g., five-tuple) of the message, hashes (hash) the flow information, and determines a message forwarding path according to the obtained hash value. Since the flow information of all messages in the same flow is the same, the obtained hash value is the same, and the selected message forwarding paths are the same. In this case, messages of a certain stream are not out of order. However, a drawback of stream-by-stream load balancing is that elephant flows (large bandwidth flows) may be concentrated on certain packet forwarding paths, resulting in uneven loading. To this end, a solution to the per-flow load balancing is to employ per-packet load balancing, which can lead to the messages of fig. 1-4 being out of order.

Illustratively, when the network device 102 sequentially receives the message 0/1/2/3/4/5 sent by the first network device 200, the network device 102 sends the message 0/2/4 to the network device 103, and the network device 102 sends the message 1/3/4 to the network device 105, the network device 107 may receive the message 4/2/5/3/1/0 due to delay jitter of the forwarding device, and the like, which results in disorder of the messages.

In summary, avoiding message misordering is a critical task in the network. It should be noted that the network device 103/104/105/106 as in fig. 1-3 or fig. 1-4 is also referred to as an out-of-order domain.

Currently, a sort window may be maintained for several messages (e.g., several messages of a stream) to avoid out-of-order messages. As shown in fig. 2-1, the sorting sliding window is composed of a flag array unit and a message buffer module, where the flag array unit (shell, SH) corresponds to the message sequence number one by one, and the message buffer module is used for buffering the message that has arrived but has not yet been sent. Wherein, the header represents the maximum message sequence number described in the sequencing sliding window, and corresponds to a flag array unit [0]; tail represents the minimum message sequence number described in the sequencing sliding window, corresponds to a marker array unit [ header-tail ], and a header-k between the header and the tail corresponds to a marker array unit [ header-k ], wherein k is a positive integer, and tail+k is smaller than the header; win_size represents the maximum number of messages that can be described in the sorting window.

When the receiving end receives a message with a sequence number greater than that of the current header, the header is modified to be the sequence number of the message, i.e. the header slides, and the new header corresponds to the flag array unit [0], the header-k between the header and the tail corresponds to the flag array unit [ k ], and the tail corresponds to the flag array unit [ header-tail ]. If the new header is greater than the tail+win_size-1 after the header is slid, the tail is modified to be the header-win_size+1 and corresponds to the tag array element [ win_size-1]. When a sequence of X (1 or more) messages has been received from the Tail in the sequencing slide window, the Tail is modified to be tail+X, i.e. the Tail slides, and a new Tail corresponds to the tag array unit [ header-Tail ]. Then, the receiving end only receives the message with the sequence number greater than or equal to the tail, and the transmitting end only transmits the message with the sequence number less than the tail.

For example, as shown in fig. 2-2, after the 81 # message arrives, the receiving end does not receive the 81 # message because the serial number is smaller than tail; as shown in fig. 2-3, after the message number 94 arrives, the header is slid to 94, the correspondence between the tag array unit and the message sequence number after the header is modified, and the tail is also modified to 86. At this time, the messages from 86 to 89 are continuously arrived and sent out, and the tail is further modified to 90.

However, the above-described technical solution has the following problems: 1. a plurality of sequencing sliding windows need to be maintained, and the expandability is not enough; 2. a large amount of storage space is needed to buffer the unsent messages; 3. a significant amount of computing resources is required to continually scan the sequencing slide to determine which messages to send. In summary, the technical scheme has high consumption of computing resources and high requirement on storage space, which results in high cost and is difficult to realize for forwarding equipment.

Therefore, the application provides a message transmission method and related equipment, in the application, after receiving a plurality of messages sent by a first user equipment, a first network equipment marks a sequence number for each message in the plurality of messages to obtain a plurality of messages carrying the sequence number, and sends the plurality of messages carrying the sequence number, so that after receiving the plurality of messages carrying the sequence number, a receiving end can sequence the plurality of messages carrying the sequence number, thereby avoiding disorder of the messages.

The foregoing embodiments describe the communication network system 100 provided by the present application, and next describe a message transmission method performed based on the communication network system 100.

In the present application, a packet transmission method is described by the first embodiment, the second embodiment, and the third embodiment, where the first embodiment is an embodiment of a load balancing manner implemented based on a deterministic internet protocol network (deterministic internet protocol, DIP), the second embodiment is an embodiment of a dual transmission and reception manner implemented based on an 802.1Qch protocol, and the third embodiment is an embodiment of a dual transmission and reception manner implemented based on DIP.

Referring to fig. 3-1, a DIP-based load balancing method is provided, and the message transmission method provided in the first embodiment of the application mainly includes the following steps:

301. the first user equipment (200) sends a plurality of messages to the first network equipment (102).

In the embodiment of the application, the first user equipment (200) may send a plurality of messages to the first network equipment (102). It should be noted that, the plurality of messages sent by the first user equipment (200) may belong to the same flow or may belong to different flows, which is not limited herein. Illustratively, in the embodiment of the present application, the first user equipment (200) may send 30 messages to the first network equipment (102), where the 30 messages belong to the same flow, and the destination device of the 30 messages is the second user equipment (300).

302. The first network device (102) marks the ordering number for each message in the plurality of messages to obtain a plurality of messages carrying the ordering number.

In some possible implementations, the ordering number includes a number of multiple levels, such as a first level number, a second level number, a third level number, and so on, and then the first network device sends messages having the same first level number among the multiple messages in one period, where the first level number is one of the multiple levels.

For example, as shown in fig. 3-2, 3 levels of ordering numbering are performed for multiple messages, respectively, and each level may be numbered sequentially from 0. For example, as shown in fig. 3-2, the message corresponding to the number 134 has a primary number of 1, a secondary number of 3, and a tertiary number of 4.

In the embodiment of the present application, the number includes 2 levels, that is, the sorting number includes a primary number and a secondary number. In the embodiment of the application, when the first network device can divide a plurality of messages belonging to the same stream into a plurality of batches, wherein all the messages in one batch correspond to one primary number, and each message in one batch corresponds to different secondary numbers. In the embodiment of the application, when the first network equipment sends the message, the message is marked with the corresponding sequencing number comprising a first-level number and a second-level number.

In some possible implementations, the numbering may be explicit or implicit. Illustratively, a string of messages is numbered (0-99) with two decimal numbers, which may be considered a primary number and one digit as a secondary number, without limitation.

303. The first network device (102) sends the plurality of messages carrying the ordering number to the transit network device (103/105).

In the embodiment of the application, the first network device sends a first partial message with the same primary number in a plurality of messages through a first message forwarding path in one period, and sends a second partial message with the same primary number in a plurality of messages through a second message forwarding path, wherein the first partial message and the second partial message are not overlapped.

For example, the first network device may send the message based on the order of the primary number and the secondary number. For example, the first network device may send all messages with a primary number of 0, and when sending all messages with a primary number of 0, may send the messages based on the order of the secondary numbers. Then, the first network device sends all the messages with the primary number of 1 again, and when sending all the messages with the primary number of 1, the messages can be sent based on the sequence of the secondary numbers.

Illustratively, after the first network device (102) performs edge shaping on 30 messages of one flow, a part of the messages are sent to the network device 103 (the first packet forwarding path), and another part of the messages are sent to the network device 105 (the second packet forwarding path), so as to implement load balancing. It should be noted that the first network device performs edge shaping in such a way that the number of bytes per cycle of each flow does not exceed bi×t, where Bi represents the bandwidth specified by the service level agreement (service level agreement, SLA) of the flow, and T is the duration of the cycle. In some possible implementations, the period may be numbered with a natural number, or may be numbered circularly (e.g., 0-3) according to a certain value, and the number of the period is marked in the message sent in the period.

For example, the first network device may send the 30 messages respectively using 3 consecutive periods (T6-T8), where 10 messages are sent per period: the primary numbers of the 1 st to 10 th messages are 17, and the secondary numbers are 0 to 9 in sequence; the primary numbers of the 11 th to 20 th messages are 18, and the secondary numbers are 0 to 9 in sequence; the first-level numbers of the 21 st to 30 th messages are 19, and the second-level numbers are 0 to 9 in sequence. Next, as shown in fig. 3-3, the first network device (102) sends the packets with the secondary numbers of 0 to 4 to the network device 103 (the first packet forwarding path), and sends the packets with the secondary numbers of 5 to 9 to the network device 105 (the second packet forwarding path), thereby realizing load balancing.

3-4, after receiving 30 messages sent by the first user device, the first network device sends messages with primary numbers 17-19 and secondary numbers 0-4 to the network device 103 through the output interface 1 in a period T6-8, and sends messages with primary numbers 17-19 and secondary numbers 5-9 to the network device 105 through the output interface 2 in a period T6-8 after edge shaping.

304. The transit network device (103/105) forwards a plurality of messages carrying the ordering numbers.

In an embodiment of the application, after receiving the message, the transit network device (103/105) forwards the message to the next hop, for example to the transit network device (104/106), and then the transit network device (104/106) forwards the message to the second network device (107).

As illustrated in fig. 3-5, the time axis corresponding to the outbound interface of each network device includes a plurality of periods of duration T. For example, as shown in fig. 3-5, in the first packet forwarding path, the duration corresponding to the outgoing interface of the first network device (102) includes a period with a duration of T: t6, T7, T8; the duration corresponding to the outgoing interface of the network device 103/105 includes a period of duration T: t7, T8, T9; the duration corresponding to the outgoing interface of the network device 104/106 includes a period of duration T: t8, T9, T10; the duration corresponding to the outgoing interface of the second network device 107 includes a period with a duration of T: t9, T10, T11.

It should be noted that, for forwarding the message, the transit network device takes a period as a time unit, and one period corresponds to one primary number. As shown in fig. 3-6, after the first network device sends a message to the network device 103, the network device 103 may perform periodic mapping. Illustratively, the period X of the last network device plus delta is the period of the next network device. Illustratively, delta=1, then period T6 of the first network device maps to period T7 in network device 103.

For example, the network device 103 sends messages with primary number 17 and secondary number 0 to 4 through the outbound interface in the period T7, sends messages with primary number 18 and secondary number 0 to 4 through the outbound interface in the period T8, and sends messages with primary number 19 and secondary number 0 to 4 through the outbound interface in the period T9. For another example, the network device 105 sends messages with primary number 17 and secondary number 5 to 9 through the outbound interface in the period T7, sends messages with primary number 18 and secondary number 5 to 9 through the outbound interface in the period T8, and sends messages with primary number 19 and secondary number 5 to 9 through the outbound interface in the period T9.

And the second network equipment receives a first partial message with the same primary number in a plurality of messages with the sequence numbers through a first message forwarding path in one period, and receives a second partial message with the same primary number in a plurality of messages with the sequence numbers through a second message forwarding path, wherein the first partial message and the second partial message are not overlapped.

305. The second network device (107) ranks the messages carrying the ranking numbers according to the ranking numbers in the messages carrying the ranking numbers, and obtains a plurality of messages after ranking.

In some possible implementations, the ordering number includes a plurality of levels of numbers, and then the second network device determines a group of gating priority queues from the plurality of groups of gating priority queues according to a first level number of the ordering number of the plurality of messages carrying the ordering number, the different first level numbers correspond to the different groups of gating priority queues, determines one gating priority queue in the corresponding group of gating priority queues according to other numbers except for the first level number of at least one message having the same first level number, obtains the ordered plurality of messages, and sends the messages in the corresponding gating priority queues to the second user device in one period.

In some possible implementations, the ordering number includes a first-level number and a second-level number, and then the second network device determines a group of gating priority queues from the plurality of groups of gating priority queues according to the first-level number of the ordering number of the plurality of messages, different first-level numbers correspond to different groups of gating priority queues, and determines one gating priority queue in the corresponding group of gating priority queues according to the second-level number of at least one message with the same first-level number, so as to obtain the ordered plurality of messages, and sends the messages in the corresponding gating priority queues to the second user device in one period.

It should be noted that, the group of gating priority queues includes a plurality of priority queues, and a group of gating priority queues corresponds to a period, and a period corresponds to a first-level number. Wherein, a group of gating priority queues is opened in a specific time interval, and the rest of time is closed, and the time intervals among the groups of gating priority queues have no intersection. The inside of each group of gating priority queues is used for dispatching Strict Priority (SP), namely, the second network device sends the message strictly according to the ordering of the secondary numbers. After a group of gating priority queues are determined for a message, a corresponding gating priority queue is determined according to other numbers except the primary number of the message. For example, a corresponding gating priority queue is determined according to the secondary number of the message.

3-7, there are M groups of gating priority queues, each group of gating priority queues has N gating priority queues, where one group of gating priority queues corresponds to one primary number, different groups of gating priority queues correspond to different primary numbers, that is, each gating priority queue in the group of gating priority queues has the same primary number, and different gating priority queues in the same group of gating priority queues correspond to different secondary numbers, so that the ordering of the messages carrying the ordering numbers is achieved.

3-8, there is a set of gating priority queues, where the set of gating priority queues corresponds to one primary number, and different sets of gating priority queues correspond to different primary numbers, i.e., each gating priority queue in the set of gating priority queues has the same primary number. Then, different gating priority queues in the same group of gating priority queues correspond to other numbers except for different primary numbers, so that the ordering of the messages carrying the ordering numbers is realized. For example, the secondary number, the tertiary number … X-order number, and the x+1-order number. Each message has a number of x+1 levels to queue a set of gating priorities and one gating priority under the set of gating priorities.

In the embodiment of the application, after a message arrives at the second network device, the second network device determines a corresponding group of gating priority queues according to the primary number of the message, and determines one gating priority queue in the group of gating priority queues according to the secondary number of the message. And then, when the group of gating priority queues are opened, sending the messages in each gating priority queue in the group of gating priority queues strictly according to the sequence of the secondary numbers.

Illustratively, as shown in FIGS. 3-9, the second network device orders the messages after the second network device receives the messages from the network device 104. The method comprises the steps of placing a message with a primary number of 17 and a secondary number of 0-9 on a gating priority queue with the number of 17; placing the messages with the primary number of 18 and the secondary number of 0-9 on a gating priority queue with the number of 18; and placing the messages with the primary number of 19 and the secondary numbers of 0-9 on a gating priority queue with the number of 19.

306. The second network device (107) sends the ordered plurality of messages to the second user device.

In the embodiment of the present application, after the second network device (107) sorts the messages, the messages may be sent to the second user device based on the sorted messages. 3-10, after receiving the messages with the primary number 17, the secondary number 0-4 and the secondary number 5-9, the second network device (107) sends the messages in the gating priority queue with the number 17 to the second user device in the period T9, and sends the messages according to the secondary number, namely, sends the messages with the secondary number 0-9 in sequence; after receiving the messages with the primary number 18, the secondary number 0-4 and the secondary number 5-9, the second network device (107) sends the messages in the gating priority queue with the number 18 to the second user device in the period T10, and sends the messages according to the secondary number, namely sends the messages with the secondary number 0-9 in sequence; after the second network device (107) receives the messages with the primary number 19, the secondary number 0-4 and the secondary number 5-9, the second network device sends the messages in the gating priority queue with the number 19 to the second user device in the period T11, and the messages are sent according to the secondary number, namely the messages with the secondary number 0-9 are sequentially sent.

In the embodiment of the application, after receiving a plurality of messages sent by a first user equipment, the first network equipment marks the sequence number for each message in the plurality of messages to obtain a plurality of messages carrying the sequence number, and sends a plurality of messages carrying the sequence number, so that after receiving a plurality of messages carrying the sequence number, the receiving end can sequence the plurality of messages carrying the sequence number, thereby avoiding disorder of the messages.

Referring to fig. 4-1, a dual transmission and reception method implemented based on an 802.1Qch protocol, provided by a second embodiment of the present application, mainly includes the following steps:

401. the first user equipment (200) sends a plurality of messages to the first network equipment (102).

Please refer to step 301, which is not described herein.

402. The first network device (102) marks the ordering number for each message in the plurality of messages to obtain a plurality of messages carrying the ordering number.

In the embodiment of the present application, the number includes 2 levels, that is, the sorting number includes a primary number and a secondary number. In the embodiment of the application, when the first network device can divide a plurality of messages belonging to the same stream into a plurality of batches, wherein all the messages in one batch correspond to one primary number, and each message in one batch corresponds to different secondary numbers.

It should be noted that, in the 802.1QCH protocol, the primary number of the ordering number may be a periodic number, and then the message may not carry the primary number, but only carry the numbers of other levels except the primary number. For example, the number includes a primary number and a secondary number, and the message may not carry the primary number, but only the secondary number. In the embodiment of the application, the description is given by taking the example that the message does not carry the primary number.

403. The first network device (102) sends the plurality of messages carrying the ordering number to the transit network device (103/105).

In the embodiment of the application, the first network device respectively sends the messages with the same primary number in a plurality of messages through the first message forwarding path and the second message forwarding path in one period, wherein the messages passing through the first message forwarding path are the same as the messages passing through the second message forwarding path.

For example, the first network device may send the message based on the order of the primary number and the secondary number. For example, the first network device may send all messages with a primary number of 0, and when sending all messages with a primary number of 0, may send the messages based on the secondary number. Then, the first network device sends all the messages with the primary number of 1 again, and when sending all the messages with the primary number of 1, the messages can be sent based on the sequence of the secondary numbers.

Illustratively, after the first network device (102) performs edge shaping on 30 messages of a flow, all the messages are sent to the network device 103 (the first packet forwarding path), and at the same time, one copy is copied and sent to the network device 105 (the second packet forwarding path), so as to implement dual transmission and reception. It should be noted that the first network device performs edge shaping in such a way that the number of bytes per cycle of each flow does not exceed bi×t, where Bi represents the bandwidth specified by the service level agreement (service level agreement, SLA) of the flow, and T is the duration of the cycle.

For example, the first network device may send the 30 messages using 3 consecutive periods (T0/T1/T0), respectively, where 10 messages are sent per period: the primary numbers of the 1 st to 10 th messages are all 0, and the secondary numbers are sequentially 0 to 9; the primary numbers of the 11 th to 20 th messages are 1, and the secondary numbers are 0 to 9 in sequence; the first-level numbers of the 21 st to 30 th messages are all 0, and the second-level numbers are sequentially 0 to 9. Next, as shown in fig. 4-2, the first network device (102) transmits the packets with the secondary numbers 0 to 9 to the network device 103 (first packet forwarding path) and the network device 105 (second packet forwarding path).

4-3, after the first network device receives 30 messages sent by the first user device, after edge shaping, the first network device sends messages with primary number of 0/1/0 and secondary number of 0-9 to the network device 103 and the network device 105 respectively through the output interface 1 in period T0/T1/T0.

404. The transit network device (103/105) forwards a plurality of messages carrying the ordering numbers.

In the embodiment of the application, after receiving the message, the transit network device (103/105) forwards the message to the next hop. For example to a forwarding network device (104/106) and the forwarding network device (104/106) forwards the message to a second network device (107).

As illustrated in fig. 4-4, the time axis corresponding to the outbound interface of each network device includes a plurality of periods of duration T. For example, as shown in fig. 4-5, in the first packet forwarding path, the duration corresponding to the outgoing interface of the first network device (102) includes a period with a duration of T: t0, T1, T0; the duration corresponding to the outgoing interface of the network device 103/105 includes a period of duration T: t1, T0, T1; the duration corresponding to the outgoing interface of the network device 104/106 includes a period of duration T: t0, T1, T0; the duration corresponding to the outgoing interface of the second network device 107 includes a period with a duration of T: t1, T0, T1.

It should be noted that, for forwarding the message, the transit network device takes a period as a time unit, and one period corresponds to one primary number. As shown in fig. 4-5, after the first network device sends a message to the network device 103, the network device 103 may perform periodic mapping. For example, if the period of the previous network device is T0 and the period of the next network device is T1, the primary number of the message is changed from 0 to 1; the period of the last network device is T1, and the period of the next network device is T0, and the primary number of the message is changed from 1 to 0. For example, the transit network device sends a message with a primary number of 1 and a secondary number of 0-9 through the outbound interface in a period T1, sends a message with a primary number of 0 and a secondary number of 0-9 through the outbound interface in a period T0, and sends a message with a primary number of 1 and a secondary number of 0-9 through the outbound interface in a period T9.

And then, the second network equipment receives the messages with the same primary number in the messages with the sequence numbers through the first message forwarding path in one period, and receives the messages with the same primary number in the messages with the sequence numbers through the second message forwarding path.

405. The second network device (107) ranks the messages carrying the ranking numbers according to the ranking numbers in the messages carrying the ranking numbers, and obtains a plurality of messages after ranking.

In the embodiment of the present application, the ordering number includes a multi-level number, and if the second network device receives a message in a certain period, it determines that the first-level number of the message is the number of the period. And the second network equipment determines a group of gating priority queues from a plurality of groups of gating priority queues according to the first-level numbers of the sequencing numbers of the messages carrying the sequencing numbers, wherein different first-level numbers correspond to different groups of gating priority queues, determines one gating priority queue in the corresponding group of gating priority queues according to other numbers except the first-level number of at least one message with the same first-level number respectively, obtains a plurality of sequenced messages, and sends the messages in the corresponding gating priority queues to the second user equipment in one period.

In some possible implementations, the ordering number includes a primary number and a secondary number, and if the second network device receives a message in a certain period, determining the primary number of the message as the number of the period. And the second network equipment determines a group of gating priority queues from the groups of gating priority queues according to the first-level numbers of the sequencing numbers of the messages, wherein different first-level numbers correspond to different groups of gating priority queues, determines one gating priority queue in the corresponding group of gating priority queues according to the second-level numbers of at least one message with the same first-level number, obtains the sequenced messages, and sends the messages in the corresponding gating priority queues to the second user equipment in one period.

It should be noted that, in the 802.1QCH protocol, the basic principle of message forwarding is as follows: 1. maintaining a transmission period of boundary alignment by all network devices; 2. in the adjacent network equipment, the message sent in a certain period of the previous hop is sent in the next period of the next hop.

4-6, among any adjacent 2 sets of gating priority queues, one set of gating priority queues corresponds to a primary number (i.e., the number of the period) of 1, and the other set of gating priority queues corresponds to a primary number (i.e., the number of the period) of 0.

Illustratively, in the first packet forwarding path, the duration corresponding to the outgoing interface of the first network device (102) includes a period with a duration of T: t0, T1, T0; the duration corresponding to the outgoing interface of the network device 103/105 includes a period of duration T: t1, T0, T1; the duration corresponding to the outgoing interface of the network device 104/106 includes a period of duration T: t0, T1, T0; the duration corresponding to the outgoing interface of the second network device 107 includes a period with a duration of T: t1, T0, T1.

For example, as shown in fig. 4-7, the network device 103/105 sends a message with a primary number of 0 and a secondary number of 0-9 through the outbound interface in a period T0; transmitting a message with a primary number of 1 and a secondary number of 0-9 through an output interface in a period T1; and sending a message with the primary number of 0 and the secondary number of 0-9 through an output interface in the period T0.

It should be noted that, for any network device, for its outbound interface, each period corresponds to a queue, each queue corresponds to a plurality of messages, the index of the queue is the number (T0/1/0) of the period, the corresponding queue is only opened in the corresponding period, and the rest of the time is closed, i.e. the network device sends the messages in the corresponding queue during the period of opening. For example, the second network device sends a message with a primary number of 1 and a secondary number of 0-9 through the outbound interface in the period T1, sends a message with a primary number of 0 and a secondary number of 0-9 through the outbound interface in the period T0, and sends a message with a primary number of 1 and a secondary number of 0-9 through the outbound interface in the period T1.

406. The second network device (107) sends the ordered plurality of messages to the second user device.

In the embodiment of the application, after the second network device orders the messages, the messages can be sent to the second user device (107) based on the ordered messages. 4-8, the second network device (107) sends messages in the gating priority queue with the number 1 to the second user device in the period T1, wherein the messages are sent according to the secondary number, that is, the messages with the secondary numbers 0-9 are sent sequentially; the second network device (107) sends the message in the gating priority queue with the number of 0 to the second user device in the period T0, and the message is sent according to the secondary number, namely the messages with the secondary numbers of 0-9 are sequentially sent; the second network device (107) sends the messages in the gating priority queue with the number 1 to the second user device in the period T1, and the messages are sent according to the secondary number, namely the messages with the secondary numbers 0 to 9 are sent in sequence.

Referring to fig. 5-1, a dual transmission and reception method based on DIP implementation, provided in a third embodiment of the present application, mainly includes the following steps:

501. the first user equipment (200) sends a plurality of messages to the first network equipment (102).

Please refer to step 301, which is not described herein.

502. The first network device (102) marks the ordering number for each message in the plurality of messages to obtain a plurality of messages carrying the ordering number.

Please refer to step 302, which is not described herein.

503. The first network device (102) sends the plurality of messages carrying the ordering number to the transit network device (103/105).

For example, the first network device may send the 30 messages respectively using 3 consecutive periods (T6-T8), where 10 messages are sent per period: the primary numbers of the 1 st to 10 th messages are 17, and the secondary numbers are 0 to 9 in sequence; the primary numbers of the 11 th to 20 th messages are 18, and the secondary numbers are 0 to 9 in sequence; the first-level numbers of the 21 st to 30 th messages are 19, and the second-level numbers are 0 to 9 in sequence. Next, as shown in fig. 5-2, the first network device (102) sends the packets with the secondary numbers of 0 to 9 to the network device 103 (the first packet forwarding path), and sends the packets with the secondary numbers of 0 to 9 to the network device 105 (the second packet forwarding path), thereby realizing load balancing.

5-3, after receiving 30 messages sent by the first user device, the first network device sends messages with primary numbers 17-19 and secondary numbers 0-9 to the network device 103 through the output interface 1 in a period T6-8, and sends messages with primary numbers 17-19 and secondary numbers 0-9 to the network device 105 through the output interface 2 in a period T6-8 after edge shaping.

504. The transit network device (103/105) forwards a plurality of messages carrying the ordering numbers.

As illustrated in fig. 5-4, in the first packet forwarding path, the duration corresponding to the outgoing interface of the first network device (102) includes a period with a duration of T: t6, T7, T8; the duration corresponding to the outgoing interface of the network device 103/105 includes a period of duration T: t7, T8, T9; the duration corresponding to the outgoing interface of the network device 104/106 includes a period of duration T: t8, T9, T10; the duration corresponding to the outgoing interface of the second network device 107 includes a period with a duration of T: t9, T10, T11.

It should be noted that, for forwarding the message, the transit network device takes a period as a time unit, and one period corresponds to one primary number. After the first network device sends a message to the network device 103, the network device 103 may perform periodic mapping. Illustratively, the period X of the last network device plus delta is the period of the next network device. Illustratively, delta=1, then period T6 of the first network device maps to period T7 in network device 103.

For example, as shown in fig. 5-5, the network device 103 sends messages with primary number 17 and secondary number 0-9 through the outbound interface in the period T7, sends messages with primary number 18 and secondary number 0-9 through the outbound interface in the period T8, and sends messages with primary number 19 and secondary number 0-9 through the outbound interface in the period T9. For another example, the network device 105 sends messages with primary number 17 and secondary number 0 to 9 through the outbound interface in the period T7, sends messages with primary number 18 and secondary number 0 to 9 through the outbound interface in the period T8, and sends messages with primary number 19 and secondary number 0 to 9 through the outbound interface in the period T9.

505. The second network device (107) ranks the messages carrying the ranking numbers according to the ranking numbers in the messages carrying the ranking numbers, and obtains a plurality of messages after ranking.

Please refer to step 305, which is not described herein.

506. The second network device (107) sends the ordered plurality of messages to the second user device.

In the embodiment of the present application, after the second network device (107) sorts the messages, the messages may be sent to the second user device based on the sorted messages. 5-6, after receiving the messages with the primary number 17 and the secondary number 0-9, the second network device (107) sends the messages with the primary number 17 in the gating priority queue to the second user device in the period T9, and sends the messages with the secondary number 0-9 in sequence; after the second network device (107) receives the messages with the primary number of 18 and the secondary number of 0-9, the second network device sends the messages in the gating priority queue with the number of 18 to the second user device in the period T10, and the messages are sent according to the secondary number, namely the messages with the secondary numbers of 0-9 are sent in sequence; after the second network device (107) receives the messages with the primary number 19 and the secondary number 0-9, the second network device sends the messages in the gating priority queue with the number 19 to the second user device in the period T11, and the messages are sent according to the secondary number, namely the messages with the secondary numbers 0-9 are sequentially sent.
