Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a traffic scheduling method, apparatus, and device for end-network collaboration. Background Art

[0002] In a DCN (Data Center Network), it is usually necessary to respond to congestion using RTT (Round-Trip Time). When congestion occurs, it is difficult for the sending end to adjust the data sending rate in a timely manner. Especially in a high-speed DCN, most data flows can be completed within 1 RTT, resulting in the failure of the scheduling control of the data flow. Under the above-mentioned reactive flow control scheme, a relatively high queue buildup usually occurs in network devices, leading to an increase in delay and even packet loss.

[0003] In related technologies, a receiver-driven Credit-based scheduling scheme has emerged. In this scheme, the sending end sends a credit trust value acquisition request to the receiving end, and the receiving end responds to the credit trust value acquisition request and sends a Credit trust value according to its receiving ability (receiving bandwidth), thereby avoiding network congestion at the receiving end and achieving proactive congestion prevention. However, the receiver-driven Credit-based congestion control scheme has the following problems:

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Among them, the described embodiments are some but not all of the embodiments of this application.

For example, A / B may mean A or B; "and / or" in the text is only a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B may mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of this application, "a plurality of" means two or more than two.

[0063] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of this application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0064] In a DCN (Data Center Network), it is usually necessary to respond to congestion with RTT (Round-Trip Time). When congestion occurs, it is difficult for the sending end to adjust the data sending rate in a timely manner. Especially in a high-speed DCN, most data flows can be completed within 1 RTT, resulting in the failure of the scheduling control of the data flow. Under the above-mentioned reactive flow control scheme, a relatively high queue buildup usually occurs in network devices, leading to an increase in latency and even packet loss.

[0065] In related technologies, a receiver-driven Credit-based scheduling scheme has emerged. As shown in the data center network Figure 1 in the figure, the network includes a sending end device, a sending network device, a switching network device, a receiving network device, and a receiving end device. In this scheme, the sending end sends a credit trust value acquisition request to the receiving end. In response to the credit trust value acquisition request, the receiving end sends a Credit trust value according to its receiving ability (receiving bandwidth), thereby avoiding network congestion at the receiving end and achieving proactive congestion prevention. However, the receiver-driven Credit-based congestion control scheme has the following problems:

[0066] The receiver-driven Credit-based scheme only has a receiver-side perspective and lacks a network perspective. When the network capacity is insufficient, network congestion cannot be avoided.

[0067] Therefore, how to efficiently and accurately schedule the traffic in the network is an urgent problem to be solved.

[0068] In view of this, the present application provides a traffic scheduling method, device, and equipment for end-network collaboration, which are used to solve the problems in the related art that there is only a receiver-side perspective and lack of a network perspective when scheduling traffic, and network congestion cannot be avoided when the network capacity is insufficient.

[0069] The inventive concept of the present application can be summarized as follows: First, receive the credit trust value from the receiver device, and determine the network acceleration ratio of the switching network according to the keep-alive information of the switching network. If it is determined that the network acceleration ratio is less than the preset value, perform bandwidth shaping on the credit trust value. Finally, forward the bandwidth-shaped credit trust value to the switching network device so that the switching network device sends the bandwidth-shaped credit trust value to the sender device.

[0070] In summary, the embodiments of the present application can overall schedule the receiver device and the receiving network device, complement the network perspective in traffic scheduling, can quickly sense the capacity change of the switching network, perform bandwidth shaping on the credit trust value when it is determined that the network acceleration ratio of the switching network is less than the preset value, and forward the bandwidth-shaped credit trust value to the switching network device, realizing the collaborative scheduling of the receiver device and the receiving network device, and ensuring the data exchange between the sender and the receiver in any scenario, which can not only improve the data transmission efficiency but also effectively avoid network congestion.

[0071] After introducing the main inventive idea of the embodiments of the present application, the following briefly introduces the application scenarios applicable to the technical solutions of the embodiments of the present application. It should be noted that the following introduced application scenarios are only for explaining the embodiments of the present application rather than limiting. In specific implementation, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.

[0072] To facilitate the understanding of the end-network collaborative traffic scheduling method provided by the embodiments of the present application, the following further illustrates this with reference to the accompanying drawings.

[0073] In a possible implementation manner, an end-network collaborative traffic scheduling method provided by the embodiments of the present application is applied to the receiving network device of the data center network. The data center network includes a sender device, a sending network device, a switching network device, a receiving network device, and a receiver device. Its overall process is as Figure 2 shown and includes the following content:

[0074] In step 201, receive the credit trust value sent by the receiving-end device in response to the credit trust value acquisition request, where the credit trust value acquisition request is sent by the sending-end device.

[0075] In step 202, determine the network acceleration ratio of the switching network according to the keep-alive information of the switching network sent by the switching network device.

[0076] The Fabric network device (i.e., the switching network device) periodically sends signaling messages to transmit the keep-alive information to the receiving network device, so that the receiving network device determines the network acceleration ratio of the switching network (i.e., the data center network). The network acceleration ratio is used to characterize the bandwidth situation of the switching network. If the network acceleration ratio is less than the preset value, it indicates that the bandwidth of the switching network is insufficient and network congestion is likely to occur; if the network acceleration ratio is greater than the preset value, it indicates that the bandwidth of the switching network is sufficient and network congestion is not likely to occur.

[0077] In step 203, if the network acceleration ratio is less than the preset value, perform bandwidth shaping on the credit trust value.

[0078] In a possible implementation manner, performing bandwidth shaping on the credit trust value in step 203 can be implemented as:

[0079] Based on the bandwidth of the switching network, shape the bandwidth of the credit trust value to be the same as the bandwidth of the switching network; where the bandwidth of the switching network is the sum of the bandwidths of multiple switching network devices.

[0080] As Figure 3 shown, in the data center network, there are 4 switching network devices and 1 switching network device (i.e., switching network device 4) fails, or the data center network itself includes 3 switching network devices. At this time, the switching network device feeds back the keep-alive information to the receiving network device, and the Credit scheduler of the receiving network device Egress1 senses that the capacity of the switching network device (i.e., the uplink bandwidth of the network) is 3 * 200G = 600G. When the traffic of all 7 receiving-end devices is fully loaded, the sum of the bandwidths of the receiving-end devices (i.e., the downlink bandwidth of the network) is 7 * 100G = 700G. Therefore, the network acceleration ratio of the switching network is 600G / 700G = 0.86, which is less than the preset value of 1. In the embodiment of the present application, the credit trust value will be subjected to bandwidth shaping by the Credit scheduler. Since the total bandwidth of the switching network devices is 600G, the bandwidth of the credit trust value is 600G. Correspondingly, in the embodiment of the present application, the bandwidth of the credit trust value will be shaped from 700G to 600G by the Credit scheduler, so that the total traffic bandwidth allowed to be sent by the receiving-end devices is 600G, ensuring network non-blocking.

[0081] Among them, the Credit scheduler is inside the receiving network device.

[0082] In step 204, the credit trust value after bandwidth shaping processing is sent to the sending device, so that the sending device sends traffic to the receiving device according to the number of traffic authorization bytes included in the credit trust value after bandwidth shaping processing.

[0083] In a possible implementation manner, if the network acceleration ratio is not less than a preset value, the credit trust value that has not undergone bandwidth shaping processing is sent to the sending device according to a preset traffic scheduling policy. Here, the switching network device is an intermediate device, which is used to receive the credit trust value that has not undergone bandwidth shaping processing and send the credit trust value that has not undergone bandwidth shaping processing to the sending device.

[0084] As Figure 4 shown, there are 4 switching network devices in the data center network. At this time, the switching network device feeds back the keep-alive information to the receiving network device, and the Credit scheduler of the receiving network device Egress1 senses that the switching network capacity (i.e., the uplink bandwidth of the network) is 4 * 200G = 800G. When the traffic of all 7 receiving devices is fully loaded, the sum of the bandwidths of the receiving devices (i.e., the downlink bandwidth of the network) is 7 * 100G = 700G. Therefore, the network acceleration ratio of the switching network is 800G / 700G = 1.14. Since 1.14 is greater than the preset value of 1, the switching network can be non-blocking. Therefore, in the embodiment of the present application, the credit trust value that has not undergone bandwidth shaping processing will be forwarded to the switching network device according to a preset traffic scheduling policy (such as RR scheduling, SP scheduling), such as RR (Round Robin) scheduling, SP (Strict Priority) scheduling, so that the switching network device sends the credit trust value that has not undergone bandwidth shaping processing to the sending device.

[0085] In a possible implementation manner, during the process of sending the credit trust value after bandwidth shaping processing to the sending device, the following two situations are included:

[0086] If the congestion state of the credit trust value queue does not reach the backpressure waterline, the credit trust value is sent to the sending device according to a preset scheduling policy;

[0087] If the congestion state of the credit trust value queue reaches the backpressure waterline, it indicates that the credit trust value queue in the receiving network device is congested. Then, a backpressure frame message is sent to the corresponding receiving device, so that the receiving device stops sending the credit trust value, and the receiving network device cannot receive the credit trust value, thereby avoiding packet loss caused by network congestion.

[0088] In another possible implementation, the present application provides a traffic scheduling method for end-network collaboration, which is applied to the sending-end device of a data center network. The data center network includes a sending-end device, a sending network device, a switching network device, a receiving network device, and a receiving-end device. As Figure 5 shown, it includes the following:

[0089] In step 501, a credit trust value acquisition request is sent to the receiving-end device, so that the receiving-end device responds to the credit trust value acquisition request and sends the credit trust value to the receiving network device.

[0090] When the Ingress end device (i.e., the sending-end device) determines that traffic has arrived, it is first stored in the corresponding queue, and then a credit trust value acquisition request Request is initiated to the destination receiving-end device corresponding to the traffic, so as to apply for the credit trust value.

[0091] In step 502, the credit trust value after bandwidth shaping processing sent by the receiving network device is received; among them, the credit trust value after bandwidth shaping processing is obtained by the receiving network device performing bandwidth shaping processing on the credit trust value.

[0092] Among them, the receiving network device performs bandwidth shaping processing on the credit trust value, including: the receiving network device determines the network acceleration ratio of the switching network according to the keep-alive information of the switching network sent by the switching network device; if the network acceleration ratio is less than the preset value, bandwidth shaping processing is performed on the credit trust value; where the network acceleration ratio is used to characterize the bandwidth situation of the switching network.

[0093] In step 503, traffic is sent to the receiving-end device according to the number of traffic authorization bytes included in the credit trust value after bandwidth shaping processing.

[0094] In a possible implementation, when the network acceleration ratio is not less than the preset value, the sending-end device in the embodiment of the present application will also receive the credit trust value that has not been subjected to bandwidth shaping processing sent by the receiving network device according to the preset traffic scheduling policy.

[0095] To sum up, the embodiments of the present application can overall schedule the receiving-end device and the receiving network device, complement the network perspective during traffic scheduling, can quickly sense the capacity change of the switching network (i.e., the data center network), perform bandwidth shaping processing on the credit trust value when it is determined that the network acceleration ratio of the switching network is less than the preset value, and forward the credit trust value after bandwidth shaping processing to the switching network device, realizing the collaborative scheduling of the receiving-end device and the receiving network device, and ensuring data exchange between the sending end and the receiving end in any scenario, which can not only improve data transmission efficiency but also effectively avoid network congestion.

[0096] Based on the same inventive concept, the present application provides a traffic scheduling device for end-network collaboration, which is applied to a receiving network device in a data center network. The data center network includes a sending end device, a sending network device, a switching network device, a receiving network device, and a receiving end device. As Figure 6 shown, the device 600 includes:

[0101] In a possible implementation manner, the credit trust value forwarding module is further configured to:

[0102] If the network acceleration ratio is not less than the preset value, send the credit trust value without bandwidth shaping processing to the sending end device according to a preset traffic scheduling policy.

[0103] In a possible implementation manner, when performing the bandwidth shaping processing on the credit trust value, the bandwidth shaping processing module is configured to:

[0104] Based on the bandwidth of the switching network, shape the bandwidth of the credit trust value to be the same as the bandwidth of the switching network; wherein, the bandwidth of the switching network is the sum of the bandwidths of multiple switching network devices.

[0105] In a possible implementation manner, during the process of sending the credit trust value after bandwidth shaping processing to the sending end device, the credit trust value forwarding module is further configured to:

[0106] If the congestion state of the credit trust value queue does not reach the backpressure waterline, the credit trust value is sent to the sending device according to a preset scheduling policy;

[0107] If the congestion state of the credit trust value queue reaches the backpressure waterline, a backpressure frame message is sent to the corresponding receiving device to cause the receiving device to stop sending the credit trust value.

[0108] Based on the same inventive concept, the present application provides a traffic scheduling device for end-network collaboration, which is applied to a sending device in a data center network. The data center network includes a sending device, a sending network device, a switching network device, a receiving network device, and a receiving device.
