Description

Background Art

[0002] With the continuous development of network-borne services, operators and users have put forward higher and higher requirements for network reliability. As an important network device, the high availability of routers plays a decisive role in network reliability. As the core part of the router, the switching network system is mainly responsible for completing the information exchange of network data packets.

[0003] The switching network system mainly includes a source line card, a target line card and a switching network board, wherein the source line card sends a data message to the target line card through the switching network board. In the prior art, there is a situation where the switching network board is prevented from being congested by adjusting the bandwidth convergence ratio between the source line card and the switching network board, but this is costly and during the data message transmission process, if the amount of data that the source line card needs to send to the target line card through the switching network board is greater than the amount of data that can be sent according to the increased bandwidth convergence ratio, the switching network board will still be congested. In addition, there is a situation where the switching network board is prevented from being congested by real-time monitoring of the delay of the data amount of each data message transmitted in the switching network board, but since the delay detection has a lag, the switching network board will still be congested. Summary of the invention

[0004] The embodiments of the present application provide a method, device and system for regulating congestion of a switching network board, thereby avoiding congestion of the switching network board.

[0005] In a first aspect, an embodiment of the present application provides a method for adjusting congestion of a switching network board, the method comprising:

[0007] Generate a first signaling request based on the data volume, send the first signaling request to the target line card corresponding to the target line card identifier through the switching network board, and receive a first signaling response sent by the target line card; the first signaling response includes at least a first amount of data to be transmitted determined by the target line card based on the priority of the first signaling request;

[0008] The data to be transmitted is sent to the target line card according to the first amount of data to be transmitted.

[0009] Compared with the prior art which adjusts the bandwidth convergence ratio between the source line card and the switching network board or monitors the data volume delay of each data message transmitted in the switching network board in real time, the present application sends a signaling application containing the data volume of the data to be transmitted to the target line card through the source line card, and after the target line card determines the signaling response containing the data volume to be transmitted according to the priority of the signaling application sent by the source line card, the data to be transmitted is sent to the target line card according to the data volume to be transmitted, thereby more accurately avoiding congestion in the switching network board.

[0010] Optionally, sending the data to be transmitted to the target line card according to the first amount of data to be transmitted includes:

[0011] Determine, based on the bandwidth of the target line card, a preset time period, and the first amount of data to be transmitted, the number of times the second signaling request is sent to the target line card through the switching network board and the amount of second data to be transmitted sent to the target line card each time;

[0012] Send the second signaling request the number of times to the target line card, and after each receipt of the second signaling response containing the second amount of data to be transmitted sent by the target line card, send the second amount of data to be transmitted to the target line card until the first amount of data to be transmitted in the data to be transmitted is sent to the target line card.

[0085] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0086] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0087] Below, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0088] (1) Line Card (LC) is a device interface between the access line and access device of a switch, router or other network device.

[0089] (2) A source line card refers to a line card that receives a data message and sends the data to be transmitted contained in the parsed data message.

[0090] (3) The target line card refers to the line card that receives the data to be transmitted from the source line card.

[0091] (4) A switching network board is used to send data from multiple source line cards to corresponding target line cards.

[0092] In practice, with the continuous development of network-borne services, operators and users have put forward higher and higher requirements for network reliability. As an important network device, the high availability of routers plays a decisive role in network reliability. As the core part of the router, the switching network system is mainly responsible for completing the information exchange of network data packets.

[0093] The switching network system mainly includes a source line card, a target line card and a switching network board, wherein the source line card sends a data message to the target line card through the switching network board. In the prior art, there is a situation where the switching network board is prevented from being congested by adjusting the bandwidth convergence ratio between the source line card and the switching network board, but this is costly and during the data message transmission process, if the amount of data that the source line card needs to send to the target line card through the switching network board is greater than the amount of data that can be sent according to the increased bandwidth convergence ratio, the switching network board will still be congested. In addition, there is a situation where the switching network board is prevented from being congested by real-time monitoring of the delay of the data amount of each data message transmitted in the switching network board, but since the delay detection has a lag, the switching network board will still be congested.

[0094] To this end, the present application provides a method for regulating congestion of a switching network board, wherein a signaling request containing the amount of data to be transmitted is sent by a source line card to a target line card, and after a signaling response containing the amount of data to be transmitted is determined by the target line card according to the priority of the signaling request sent by the source line card, the data to be transmitted is sent to the target line card according to the amount of data to be transmitted, thereby more accurately avoiding congestion in the switching network board.

[0095] After introducing the design ideas of the embodiments of the present application, the following briefly introduces the application scenarios to which the technical solutions of the embodiments of the present application can be applied. It should be noted that the application scenarios introduced below are only used to illustrate the embodiments of the present application and are not limited. In specific implementation, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.

[0096] refer to Figure 1, which is a schematic diagram of an application scenario of the method for regulating the congestion of a switching network board provided in an embodiment of the present application. The application scenario includes line card 1, line card 2, line card 3, line card 4 and a switching network board. Assuming that line card 1 receives a data message, line card 1, as a source line card, parses the received data message to obtain the target line card identifier corresponding to the data message, the data volume of the data message, and the data to be transmitted contained in the data message. Assuming that the target line card is determined to be line card 3 according to the target line card identifier, line card 1 generates a first signaling request based on the data volume, sends the first signaling request to line card 3 through the switching network board, and line card 3 generates a first signaling response containing at least the first amount of data to be transmitted based on the priority of the first signaling request, and sends the first signaling response to line card 1, so that line card 1 sends the data to be transmitted to line card 3 according to the first amount of data to be transmitted.

[0097] Of course, the method provided in the embodiment of the present application is not limited to Figure 1 The application scenarios shown can also be used in other possible application scenarios, and the embodiments of the present application are not limited thereto. Figure 1 The functions that can be implemented by each device in the application scenario shown will be described in the subsequent method embodiments, and will not be described in detail here.

[0098] To further illustrate the technical solution provided by the embodiment of the present application, this is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiment of the present application provides the method operation steps shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided by the embodiment of the present application.

[0099] Combine the following Figure 1 The application scenario shown illustrates the technical solution provided by the embodiment of the present application.

[0100] refer to Figure 2 , the embodiment of the present application provides a method for adjusting the congestion of a switching network board, comprising the following steps:

[0101] S201, parsing a received data message to obtain a target line card identifier corresponding to the data message, a data volume of the data message, and data to be transmitted contained in the data message.

[0102] like Figure 3As shown, it is assumed that line card 1 and line card 2 are both source line cards, line card 3 is the target line card, line card 1 and line card 2 send data to line card 3 through the switching network board, line card 1, line card 2 and line card 3 all include panel port 1, panel port 2, ..., panel port n (n is a positive integer), and the bandwidth of line card 1, line card 2 and line card 3 is the sum of the bandwidth of their corresponding panel port 1, panel port 2, ..., panel port n. For example, if the bandwidth of panel port 1, panel port 2, ..., panel port n corresponding to line card 1 is 10G, then the bandwidth of line card 1 is 10nG.

[0103] After line card 1 and line card 2 receive the data message, they parse the data message and determine that the target line card is line card 3 according to the target line card identifier corresponding to the data message. At the same time, line card 1 can also obtain the data volume of the data message is 200G and the data to be transmitted contained in the data message according to the parsing result. Line card 2 can also obtain the data volume of the data message is 100G and the data to be transmitted contained in the data message according to the parsing result.

[0104] S202, generate a first signaling request based on the data volume, send the first signaling request to the target line card corresponding to the target line card identifier through the switching network board, and receive a first signaling response sent by the target line card; the first signaling response includes at least a first amount of data to be transmitted determined by the target line card based on the priority of the first signaling request.

[0105] For example, Figure 3 As shown, line card 1 as a source line card may further include a signaling management unit 1, wherein the signaling management unit 1 includes a signaling register 11 corresponding to target line card 1, a signaling register 12 corresponding to target line card 2, ..., and a signaling register 1n corresponding to target line card n. Similarly, line card 2 also includes a signaling management unit 2, wherein the signaling management unit 2 includes a signaling register 21 corresponding to target line card 1, a signaling register 22 corresponding to target line card 2, ..., and a signaling register 2n corresponding to target line card n.

[0106] Line card 3 as a target line card may further include a scheduling management unit 1, wherein the scheduling management unit 1 includes a signaling application counter 1 corresponding to source line card 1, a signaling application counter 2 corresponding to source line card 2, ..., a signaling application counter n corresponding to source line card n.

[0107] Assume that the data volume in the first signaling request sent by line card 1 is 200G, and the data volume in the first signaling request sent by line card 2 is 100G. Line card 3 is the target line card. After receiving the first signaling request containing 200G data volume sent by line card 1 and the first signaling request containing 100G data volume sent by line card 2, if it is determined that the priority of the first signaling request of line card 1 is lower than the priority of the first signaling request of line card 2, the 200G data volume that line card 3 can receive is allocated to line card 1 as 100G data volume, and the 100G data volume is allocated to line card 2. That is, the first signaling response of line card 1 contains at least 100G of the first data volume to be transmitted, and the first signaling response of line card 2 contains at least 100G of the first data volume to be transmitted. Therefore, line card 1 and line card 2 can continue to send multiple second signaling requests to line card 3 respectively, so as to send the data of the first data volume to be transmitted of 100G that each needs to transmit to line card 3.

[0108] Since there are times in the signaling register corresponding to each target line card in the signaling management unit of the source line card, the source line card can send a second signaling request to the corresponding target line card. In order to reduce the delay in sending data from the source line card to the corresponding target line card, a preset number of times can be allocated to the signaling register corresponding to each target line card.

[0109] Specifically, the source line card includes a pre-allocated number of times for sending a second signaling request to the target line card. If the source line card sends the second signaling request to the target line card through the switching network board, the pre-allocated number is reduced; if the source line card receives the second signaling response sent by the target line card through the switching network board, the pre-allocated number is increased; when the pre-allocated number is less than or equal to zero, the data to be transmitted in the source line card is discarded to facilitate regulating the congestion of the switching network board.

[0110] Continuing with the above example, assuming that the target line card 1 in the signaling management unit 1 in line card 1 is line card 3, and the source line card 1 in the scheduling management unit 1 in line card 3 is line card 1, then line card 1 sends a second signaling request to line card 3 once, the number in the signaling register 11 decreases by one, line card 1 receives a second signaling response sent by line card 3 once, and the number in the signaling register 11 increases by one. Line card 3 receives a second signaling request sent by line card 1 once, the number in the signaling application counter 1 increases by one, line card 3 sends a second signaling response to line card 1 once, and the number in the signaling application counter 1 decreases by one.

[0111] For example, the number of pre-allocations for the signaling register 11 is 3. When the number of pre-allocations is reduced to 0 and the second signaling response is still not received, the data to be transmitted in the line card 1 is discarded to avoid congestion of the switching network board.

[0112] S203: Send the data to be transmitted to the target line card according to the first amount of data to be transmitted.

[0113] Specifically, based on the bandwidth of the target line card, the preset time period and the first amount of data to be transmitted, the number of times the second signaling request is sent to the target line card through the switching network board and the second amount of data to be transmitted sent to the target line card each time are determined, the second signaling request is sent to the target line card a certain number of times, and after each time a second signaling response containing the second amount of data to be transmitted is received from the target line card, data of the second amount of data to be transmitted is sent to the target line card until the data of the first amount of data to be transmitted in the data to be transmitted is sent to the target line card.

[0114] For example, the quotient obtained by dividing the bandwidth of the target line card by the preset time period is determined as the second amount of data to be transmitted sent to the target line card each time; the first amount of data to be transmitted is divided by the second amount of data to be transmitted to determine the number of times the second signaling request is sent to the target line card.

[0115] For example, if the bandwidth of the target line card is 400G and the preset time period is 10us, the second amount of data to be transmitted sent to the target line card each time is 400G / 10us=4Mbit. If the first amount of data to be transmitted is 100G, the number of times the second signaling request is sent to the target line card is 100G / 4Mbit=25000 times.

[0116] In one embodiment of the present application, when the target line card includes multiple target ports of different priorities, the received data packet is parsed to obtain the target port identifier in the target line card corresponding to the data packet, the data volume of the data packet, and the data to be transmitted contained in the data packet.

[0117] like Figure 4 As shown, assuming Figure 3 The line card 3 in the example includes a target port 31 and a target port 32, and the priority of the target port 31 is higher than the priority of the target port 32, the target port 31 includes a queue 311 and a queue 312, the target port 32 includes a queue 321 and a queue 322, and the priority of the queue 311 is higher than the priority of the queue 312, and the priority of the queue 321 is higher than the priority of the queue 322. The queue 311, the queue 312, the queue 321 and the queue 322 respectively include a scheduling management unit, wherein each scheduling management unit includes a signaling application counter 1 corresponding to the source line card 1, a signaling application counter 2 corresponding to the source line card 2, ..., a signaling application counter n corresponding to the source line card n (n is a positive integer).

[0118] Assume that the first amount of data to be transmitted sent by line card 1 to line card 3 is 300G, of which 10G is sent to queue 311 and 290G is sent to queue 312. Since the priority of queue 311 is higher than that of queue 312, the 10G data sent to queue 311 will be sent first. By further setting the priority of the target line card, the source line card can parse the data message and transmit the data to the corresponding target port more accurately, avoiding congestion in the switching network board.

[0119] like Figure 5 As shown, a schematic diagram of the flow of interaction between a source line card, a switching network board, and a target line card in a system for adjusting switching network board congestion provided by an embodiment of the present application is shown, including the following steps:

[0120] S501, the source line card parses the received data message, obtains the target line card identifier corresponding to the data message, the data volume of the data message, and the data to be transmitted contained in the data message, and generates a first signaling request based on the data volume;

[0121] S502, the source line card sends the first signaling request to the target line card corresponding to the target line card identifier through the switching network board;

[0122] S503, the target line card generates a first signaling response including at least a first amount of data to be transmitted based on the priority of the first signaling request;

[0123] S504, the target line card sends the first signaling response to the source line card through the switching network board;

[0124] S505, the source line card determines the number of times the second signaling request is sent to the target line card through the switching network board and the second amount of data to be transmitted to the target line card each time based on the bandwidth of the target line card, the preset time period and the first amount of data to be transmitted, and pre-allocates the number of times for the second signaling request;

[0125] S506, the source line card sends a second signaling request to the target line card a number of times, and after receiving a second signaling response including a second amount of data to be transmitted sent by the target line card, sends data of the second amount of data to be transmitted to the target line card each time, until the data of the first amount of data to be transmitted in the data to be transmitted is sent to the target line card completely;

[0126] S507, if the source line card sends a second signaling request to the target line card through the switching network board, the pre-allocation times are reduced; if the source line card receives a second signaling response sent by the target line card through the switching network board, the pre-allocation times are increased; when the pre-allocation times are less than or equal to zero, the data to be transmitted in the source line card are discarded.

[0133] Send a second signaling request to the target line card a number of times, and after each receipt of a second signaling response containing a second amount of data to be transmitted sent by the target line card, send data of the second amount of data to be transmitted to the target line card until the first amount of data to be transmitted in the data to be transmitted is sent to the target line card.

[0136] If the source line card receives a second signaling response sent by the target line card through the switching network board, the pre-allocated times are increased;

[0137] When the pre-allocation times are less than or equal to zero, the data to be transmitted in the source line card is discarded to facilitate adjusting the congestion of the switching network board.

[0138] Optionally, the sending module 603 determines the number of times the second signaling request is sent to the target line card through the switching network board and the second amount of data to be transmitted sent to the target line card each time based on the bandwidth of the target line card, the preset time period and the first amount of data to be transmitted, which is specifically used to:

[0139] The quotient obtained by dividing the bandwidth of the target line card by the preset time period is determined as the second amount of data to be transmitted sent to the target line card each time;

[0140] The number of times the second signaling request is sent to the target line card is determined by dividing the first amount of data to be transmitted by the second amount of data to be transmitted.

[0141] Optionally, the target line card includes a plurality of target ports of different priorities, and the parsing module 601 parses the received data message to obtain the target line card identifier corresponding to the data message, the data volume of the data message, and the data to be transmitted contained in the data message, which is specifically used for:

[0142] The received data message is parsed to obtain the target port identifier in the target line card corresponding to the data message, the data volume of the data message, and the data to be transmitted contained in the data message.

[0144] The receiving module 701 is used to receive a first signaling request sent by a source line card through a switching network board; the first signaling request is generated based on the data volume, and the data volume is obtained after the source line card parses the received data message;

[0146] Optionally, after sending the first signaling response to the source line card, the generating module 702 is further configured to:
