Fig. 4 is an architectural diagram of a logical network according to one embodiment of the present invention.
As shown in fig. 4, in one embodiment, the number of network hierarchy levels and the first network capacity of each network hierarchy level are determined based on the first network capacity requirement of the data center, the network hierarchy level includes one or more network roles, the composition of each network hierarchy level and the first network capacity of each network role are respectively determined according to the first network capacity of each network hierarchy level, and the relationship between each network role is established. Specifically, the first network capacity requirement of the data center may be a requirement of hardware resources such as a port rate, a port number, a hardware table entry, and a memory size. The scale of the data center network is determined according to a first network capacity requirement of the data center, and the number of network levels and the scale of each network level (i.e., the first network capacity) are determined based on the size of the network scale, for example, the number of network levels in fig. 4 may be 3, each network level is respectively a DC (data center), a POD (Point of discovery, basic physical design unit of the data center), and a RACK (data center cabinet for placing a server and a network device), and the scales of the network levels of the DC, the POD, and the RACK are determined step by step based on the first network capacity requirement of the data center. Based on the scale of each network hierarchy, the composition of the network roles in each network hierarchy and the first network capability of each network role are determined, for example, in fig. 4, RACK may be composed of network devices with multiple Server and Leaf roles, POD may be composed of network devices with multiple RACK and Spine roles, and DC may be composed of network devices with multiple POD and Super Spine roles. The Server is a Server, a computer bearing various services is connected with a Leaf switch through a network card, the Leaf is an access switch and used for converging the flow of the Server and completing communication between the servers, the Spine is a convergence switch and used for converging the flow of the Leaf switch and completing communication between the leaves, and the Super Spine is a core switch and used for converging the flow of the Spine switch and completing communication between the spines. Specifically, when creating a DC, it is necessary to define a logical resource pool (IP, ASN, VNI, VLAN, etc.), add a Super Spine role, and define POD attributes (number of devices, number, interconnection attributes, etc.); when a POD is created, a Spine role needs to be added, and RACK attributes (the number of devices, interconnection attributes, and the like) are defined; when creating RACK, a Leaf role needs to be added, and Server attributes (number of devices, number, interconnection attributes, etc.) are defined.

Each network layer is composed of different network roles, and a network planner or a network architect can flexibly select the connection relation between the logic network equipment and each network role according to the requirement to form a reusable arbitrary network layer or network networking unit template, and carry out standardized network design, construction and operation through the network template.
FIG. 5 is a schematic diagram of a network character model according to one embodiment of the invention.
As shown in fig. 5, in an embodiment, a logical network device corresponding to a network role is generated according to a first network capability of each network role, and a mapping relationship between the network role and the logical network device is established to generate a network role model. Specifically, the network role is a role definition performed on devices in the network architecture, which bear different network functions, and can be flexibly added and deleted according to specific scenes, for example, the network role can be a Server, a Leaf, a Spine, or a Super Spine, and the naming of the network role can be customized and specified without strict standards. When modeling the network role, the difference of shielding equipment manufacturers only takes the network capabilities required by different roles as a starting point to abstract, and the logic network equipment of the required network role is formed by modularly superposing the different network capabilities. The points in fig. 5 correspond to the network role, the logical network device, and the first network capability, respectively, and the edge is an association relationship between the two points. The capacity required by the logic network device is determined according to the function requirements of each network role, the logic network device with any port rate can be defined through the flexible combination of the first network capacity (the port rate is taken as the network capacity as an example), and meanwhile, the same device can be used as a plurality of network roles for network design. One network role may have one or more logical network devices corresponding to it, so long as the function meets the function requirement of the network role, the same network role may be assumed by multiple logical network devices, and similarly, one logical network device can also serve multiple roles, and generally, the more powerful logical network devices can serve more roles, in fig. 5, a LogicDevice1 has two edges pointing to 48 × 10G network capability and 48 × 25g network capability, which means that the LogicDevice1 has two network capabilities, which respectively represent that a port with a 10G rate has 48 ports and a port with a 25G rate has 48 ports. All network levels can be defined as network level templates, so that the network level templates are directly used in each network design or planning, for example, a RACK network level comprises 1 Leaf switch and 4 servers, the RACK network level can be defined as RACK template a, and the RACK template a can be directly used for multiplex design in other network architectures.
In one embodiment, the second network capability of each logical network device is determined based on a second network capability requirement of the data center, where the second network capability requirement may be a requirement of a network function, such as configuring an IP address, configuring a device name, and the like. The configuration module is a configuration unit associated with the logical network device, and can perform capability configuration on the physical network device according to the configuration module. The configuration modules can be combined into a configuration template of the network equipment, the configuration template is a bridge for connecting a logic network and a physical network, the logic network represents the design target of the network, the physical network represents the actual state of the network, a set of configuration templates are associated with the logic network equipment, and meanwhile, a certain model of equipment of a certain actual network equipment manufacturer bears the role of the network, so that the functions of the associated configuration modules in the configuration template are realized. And each logic network device determines one or more corresponding configuration modules according to the functional units which are required to be realized, wherein each logic network device can be determined according to the second functional requirements of the data center network according to the functional units which are required to be realized.
In one embodiment, for each logical network device, a physical network device satisfying the network capability of the logical network device is determined using a pre-configured network capability attribute template, and a mapping relationship is established between the logical network device and the physical network device satisfying the network capability of the logical network device. Specifically, each manufacturer may have its own network capability attribute template, where the network capability attribute template includes a configuration module corresponding to a physical network device of the manufacturer and a mapping relationship between the physical network device and each logical network device.
