DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0014] Next, in conjunction with the accompanying drawings, a traffic control method, an electronic device, a storage medium, and a program product provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0015] Figure 1 A traffic control method provided by an embodiment of the present application is shown. The method includes the following steps: Step S102: When a part of the link between the core switch in the backbone layer and the receiving switch in the leaf layer is disconnected, obtain the first quantity of the non-disconnected links between the core switch and the receiving switch.

[0016] The embodiment of the present application is applied to a data network center with a Spine-Leaf architecture. The Spine-Leaf architecture is a data center network topology composed of two switching layers, Spine and Leaf. The Leaf layer consists of switches that aggregate traffic from servers and are directly connected to the Spine or the network core. The Spine switches interconnect all Leaf switches in a full-mesh topology. When link failures such as optical module failures, switch port failures, or fiber optic link disconnections occur in the data network center with a Spine-Leaf architecture, it will cause a part of the link between the core switch in the backbone layer and the receiving switch in the leaf layer to be disconnected. In the embodiment of the present application, when a part of the link between the core switch in the backbone layer and the receiving switch in the leaf layer is disconnected, the first quantity of the non-disconnected links between the core switch and the receiving switch can be obtained.

[0017] In one implementation, obtaining the first quantity of the non-disconnected links between the core switch and the receiving switch includes: setting the core switch and the receiving switch as a load sharing group; setting a unique number for each link in the load sharing group; and obtaining the first quantity according to the unique number.

[0018] In the embodiments of the present application, each switch in the leaf layer (Leaf) of the data center network and its BGP neighbor can be set as the same load sharing group first. In the data center network, each switch in the leaf layer is connected to the switch in the backbone layer (Spine) through the BGP protocol. Each switch in the Leaf layer belongs to a "load sharing group" (which can be understood as a set composed of multiple links) on the Spine, that is, the switch on the Spine and the switch on the leaf are BGP neighbors to each other. BGP (Border Gateway Protocol) is a path vector routing protocol used to exchange routing information between different autonomous systems (AS). It is the basic protocol for the core routing of the current Internet and is responsible for coordinating the selection of traffic transmission paths between various networks in the global Internet.

[0019] Since in a traffic transmission process, the switches in the leaf layer can be divided into receiving switches for receiving traffic and sending switches for sending traffic, in the traffic transmission process, the core switch in the backbone layer (Spine) and the sending switch for sending traffic can be set as the same load sharing group. The core switch and the receiving switch for receiving traffic are set as the same load sharing group.

[0020] In the same load sharing group, a unique number can be automatically assigned to each BGP neighbor member (link) in the normal state (UP). The number value can range from 1 to the total number N of links in the normal state in the load sharing group, as follows Figure 2 As shown, the core switch Spine1 in the Spine layer forms a load sharing group with Leaf1, Leaf2, and Leaf3 in the Leaf layer respectively. Spine2 can also form a load sharing group with Leaf1, Leaf2, and Leaf3 in the Leaf layer respectively. Each load group has 2 links numbered 1 and 2. Among them, Leaf1 can be a sending switch and Leaf2 can be a receiving switch.

[0021] For the traffic transmission process where traffic is transmitted from the sending switch to the receiving switch, relative to the core switch, the next-hop path of the route comes from the same load-sharing group. At this time, if some links between the core switch and the receiving switch are disconnected, that is, when the existing member neighbors of the load-sharing group are disconnected, the first quantity of the non-disconnected links between the core switch and the receiving switch can be obtained according to the link numbers in the load-sharing group.

[0022] Step S104: Control the traffic transmission rate between the sending switch and the core switch according to the second quantity of the links between the core switch and the sending switch in the leaf layer and the first quantity.

[0023] In the embodiment of the present application, the traffic sent by the sending switch is transmitted to the receiving switch through the core switch. Therefore, the embodiment of the present application can obtain the second quantity of the links between the core switch and the sending switch in the leaf layer, and then control the traffic transmission rate between the sending switch and the core switch according to the above first quantity and the second quantity. In the embodiment of the present application, the links between the sending switch and the core switch are all in a normal state.

[0024] In one implementation manner, the controlling the traffic transmission rate between the sending switch and the core switch according to the second quantity of the links between the core switch and the sending switch in the leaf layer and the first quantity includes: when the second quantity is greater than the first quantity, obtain the ratio between the second quantity and the first quantity, and reduce the traffic transmission rate between the sending switch and the core switch.

[0025] After obtaining the first quantity of the non-disconnected links between the core switch and the receiving switch and the second quantity of the links between the core switch and the sending switch in the leaf layer, the first quantity and the second quantity can be compared. If the second quantity is greater than the first quantity, it means that the number of normal links between the core switch and the sending switch is more than the number of links between the core switch and the receiving switch. Since there are some links disconnected between the core switch and the receiving switch, if the traffic transmission rate between the sending switch and the core switch is not reduced at this time, traffic congestion will occur when the core switch forwards the traffic to the receiving switch.

[0026] Therefore, in the embodiment of the present application, if it is determined that the second quantity of the links between the core switch and the sending switch is greater than the first quantity of the non-disconnected links between the core switch and the receiving switch, the traffic transmission rate between the sending switch and the core switch can be reduced according to the ratio between the second quantity and the first quantity, so that the traffic is transmitted from the sending switch to the core switch.

[0027] For exampleFigure 3 As shown, the traffic flows out from the sending switch Leaf1, is forwarded by the core switch Spine1 to the receiving switch Leaf2. At this time, the number of links between the sending switch Leaf1 and the core switch Spine1 is 2, and the number of links between the core switch Spine1 and the receiving switch Leaf2 is also two. However, since one link between the core switch Spine1 and the receiving switch Leaf2 is disconnected, the first number of the non-disconnected links between the core switch Spine1 and the receiving switch Leaf2 is 1. Then, at this time, the routing ratio of the traffic going to the receiving switch Leaf2 through the core switch Spine1 can be reduced, that is, the traffic transmission rate between the sending switch Leaf1 and the core switch Spine1 can be reduced. The traffic transmission rate between the sending switch Leaf1 and the core switch Spine1 can be reduced to 1 / 2 of the initial rate according to the ratio of the second number to the first number.

[0028] The traffic control method provided by the embodiments of the present application, when some links between the core switch in the backbone layer and the receiving switch in the leaf layer are disconnected, obtains the first number of the non-disconnected links between the core switch and the receiving switch; controls the traffic transmission rate between the sending switch and the core switch according to the second number and the first number of the links between the core switch and the sending switch in the leaf layer. The traffic sent by the sending switch is transmitted to the receiving switch through the core switch, and can combine the number of the non-disconnected links between the core switch and the sending switch and the receiving switch respectively to control the traffic transmission rate, intelligently share the proportional traffic to different switch devices, prevent the egress traffic congestion of the switch devices, and improve the utilization rate of the bandwidth.

[0029] In one implementation, the controlling the traffic transmission rate between the sending switch and the core switch according to the second number and the first number of the links between the core switch and the sending switch in the leaf layer includes: when the second number is less than or equal to the first number, controlling the traffic transmission rate between the sending switch and the core switch to remain unchanged.

[0030] In the embodiments of the present application, when some links between the core switch and the receiving switch are disconnected, if it is obtained that the second number of the links between the core switch and the sending switch is less than or equal to the first number of the non-disconnected links between the core switch and the receiving switch, it means that after the traffic sent by the sending switch reaches the core switch, there are still enough links to forward the traffic to the receiving switch. At this time, the core switch will not have traffic congestion either. Therefore, the traffic transmission rate between the sending switch and the core switch can be controlled to remain unchanged to ensure the stable transmission of the traffic.

[0031] In one implementation, reducing the traffic transmission rate between the sending switch and the core switch includes: controlling the core switch to send a low-priority route to the sending switch to control the sending switch to reduce the traffic transmission rate between it and the core switch.

[0032] In the embodiment of the present application, when a part of the link between the core switch and the receiving switch is disconnected, if the second number of links between the core switch and the sending switch obtained is greater than the first number of non-disconnected links between the core switch and the receiving switch, the core switch can be controlled to send a low-priority route to the sending switch to inform the sending switch to reduce the traffic transmission rate between it and the core switch. The low-priority route can be a route with a lower local pref value, or a route with a higher med attribute value or other implementation manners. In this way, the traffic transmission rate can be controlled by combining the number of non-disconnected links between the core switch and the sending switch and the receiving switch respectively, and the proportional traffic can be intelligently shared to different switch devices, preventing the egress traffic congestion of the switch devices and improving the utilization rate of the bandwidth.

[0033] In one implementation, keeping the traffic transmission rate between the sending switch and the core switch unchanged includes: controlling the core switch to send a normal route to the sending switch to control the traffic transmission rate between the sending switch and the core switch to remain unchanged.

[0034] In the embodiment of the present application, when a part of the link between the core switch and the receiving switch is disconnected, if the second number of links between the core switch and the sending switch obtained is less than or equal to the first number of non-disconnected links between the core switch and the receiving switch, the core switch can be controlled to send a normal route to the sending switch to inform the sending switch to keep the traffic transmission rate between it and the core switch unchanged and ensure the stable traffic transmission.

[0035] In one implementation, after obtaining the first number of non-disconnected links between the core switch and the receiving switch, it further includes: controlling the traffic transmission rate between the sending switch and other core switches in the backbone layer except the core switch to remain unchanged.

[0036] In the embodiment of the present application, the sending switch can also transmit the traffic to the receiving switch through other core switches in the backbone layer except the core switch, such as Figure 3As shown in the figure, the sending switch Leaf1 can also transmit traffic to the receiving switch Leaf2 through another core switch Spine2. Therefore, when the traffic transmission rate between the sending switch and the core switch is reduced, since the traffic transmission link of Leaf1-Spine2-Leaf2 is not affected, the traffic transmission rate of the traffic transmission link of Leaf1-Spine2-Leaf2 does not need to be changed. Figure 3 As shown in the figure, the ratio of the traffic transmission rate between the sending switch Leaf1 and the core switch Spine1 to the traffic transmission rate between the sending switch Leaf1 and the other core switch Spine2 is 1:2. In this way, it is ensured that there will be no traffic congestion on the Leaf1-Spine2-Leaf2 link, and the traffic transmission efficiency between the switch and other core switches is also guaranteed.

[0037] In the embodiments of the present application, Figure 3 As shown in the figure, when one link (part of the link) between Spine1 and Leaf2 is disconnected, Spine1 notifies Leaf1 of the low-priority route, allowing Leaf1 to share the traffic to the server connected to Leaf2 with Spine1 and Spine2 in a 1:2 ratio, so that the traffic egress from Spine1 to Leaf2 will not be congested. In the event of a link failure between a Leaf switch and a Spine switch, the overall bandwidth utilization of traffic from Leaf1 to Leaf2 via Spine1 / Spine2 is increased from 1 / 2 to 3 / 4, and this effect increases as the number of Spine switches increases (from 3 / 6 to 5 / 6 when there are 3 Spine switches; from 4 / 8 to 7 / 8 when there are 4 Spine switches, and so on).
