Their high-level switches and routers are prone to routing bottlenecks, and their network structure lacks flexibility and scalability. Their core switches and servers are single failure nodes of the entire network architecture, which cannot effectively guarantee the safe operation of the entire cloud computing data center network. In addition, the use of high-end core switches and servers and other equipment will increase the cost of constructing the entire cloud computing data center network.

[0017] from Figure 1 As can be seen in the example of the method for constructing the network topology structure of the cloud computing data center, the switches and servers are arranged in such a way that one switch and the servers connected to its ports are regarded as a unit. Each switch column includes four 4-port switches, and each server column includes ten dual-port servers. Figure 3 A switch and the servers connected to its ports are shown as a unit. In this example, a 4-port switch is used.

[0018] The switches and servers in the arrangement are connected in accordance with certain connection rules; wherein the scale of the cloud computing data center network topology structure of the present invention is determined by and These two global variables determine, The value of determines the number of switches and server units in each column in the cloud computing data center network topology, and Determines the number of servers in each switch and server unit; these two together determine the structure of the cloud computing data center network.

Each layer of the network has two servers in a column, namely the top server and the bottom server. Each switch in the switch column is connected to 4 servers in turn as a unit, so that 5 switches can successfully connect to 20 servers.

[0020] like Figure 1 As shown, the numbering strategy of the switches in this embodiment is as follows: To uniquely identify the location coordinates of the switch, , , and is an integer; the leftmost switch column in the arrangement is the starting switch column, and the left and right ports of the 4-port switches in the switch column are each connected to two servers; the horizontal coordinate value of each switch column is determined by the relative order of the switch column in all switch columns, and the starting horizontal coordinate of the switch is set to 0 and increases to the right; the bottom switch in each switch column is the starting vertical coordinate, and the starting vertical coordinate of the switch is set to 0 and increases upward in sequence. The vertical coordinate of each switch is the number of switches above the switch in the switch column where the switch is located plus 1; the coordinate number of each switch is as follows Figure 1 shown.

[0021] The server column numbering strategy in this embodiment is as follows: each switch port is connected to multiple corresponding servers, and the switch ports connected to the servers are numbered 1, 2, ..., ,in , ;against Figure 1 For example, the bottom server connected to the lower left port of each switch is numbered 1, and the top server connected to the upper left port is numbered 2; the bottom server connected to the lower right port of the switch is numbered 3, and the top server connected to the upper right port is numbered 4; each switch is connected to the corresponding 4 servers numbered 1, 2, 3, and 4 as a unit, and the coordinate number of each server is as follows: Figure 1 As shown; In order to distinguish servers connected to different switches, an example is given for servers connected to different switches, such as We number the switch's server number 1 as .

[0022] After the corresponding numbers, the switch in this embodiment is connected to the server according to the connection strategy provided by the present invention: Figure 1 As shown in the example, for any layer of the cloud computing data center network, there are 5 columns of switches and 10 columns of servers; in the network topology structure of the present invention, each switch is interconnected with the servers in the same unit corresponding to its port, and the servers corresponding to each switch are respectively connected to the servers corresponding to multiple switches in each layer, so that the servers are twisted and folded to form the network topology architecture of the present invention.

[0023] In the present invention, each switch is connected to the server corresponding to its port in the same unit. The special feature of this network topology is the connection between servers at each layer of the network. The specific connection between servers is as follows:

[0024] like Figure 1 As shown, the first layer network number (0,0) switch is the starting point, and its port corresponds to the bottom server No. 1 Connect to the port of the (0,0) switch to the right, and then connect to the bottom server No. 3 corresponding to the (0,0) switch ; afterwards Server connects right Server, then connect to the (0,1) switch, and then continue to connect No. server; the bottom server of the first layer of the network Connect servers and switches to the right in order, especially the bottom server of the first layer network The other port is connected to the fourth layer network The servers are connected to form a Mobius closed-loop network structure; similarly, the fourth layer network The other port of the server is connected to the Layer 1 network The servers are interconnected to form a closed loop.
