Embodiment 1
[0052] In Embodiment 1 of the present invention, a service network traffic modeling method is provided, such as image 3 As shown, it specifically includes the following steps:
[0053] S301. Establish a network flow diagram of the service network,
[0054] Wherein, the network flow graph includes nodes representing network element nodes in the service network, and edges between nodes representing links between network element nodes in the service network.
[0055] Furthermore, the flow of the service network can be described by a bidirectional graph. Figure 4 In order to describe the schematic diagram of the network flow of the service network, the network flow graph can be described as: G=(V, E), wherein, V is a set of nodes, and E is a set of links between nodes. Node V represents a network element node in a service network, including both a data source node and a data receiver node. Edge E is bidirectional, indicating the flow direction between network element nodes in...
Embodiment 2
[0106] Based on a service network traffic modeling method provided by an embodiment of the present invention, in Embodiment 2 of the present invention, a network resource scheduling method is provided, such as Figure 8 As shown, it specifically includes the following steps:
[0107] S801. Establish a network resource information map of the physical network,
[0108] Wherein, the network resource information graph includes nodes representing network element nodes in the physical network, and edges between nodes representing links between network element nodes in the physical network.
[0109] S802. For every two network element nodes with links in the physical network, respectively determine the link capacity of the link between the network element nodes, the current occupancy rate of the link, link performance information, link traffic type information, and CPU usage of the end nodes forming the link.
[0110] In this step, the link performance information may include: link...

Abstract
Embodiments of the invention provide a business network traffic modeling method, a network resource scheduling method and a network element. The business network traffic modeling method comprises the following steps of establishing a network traffic diagram of a business network; counting the total traffic between two network element nodes with links and taking the total traffic as an attribute value of a traffic attribute of an edge for corresponding nodes of the two network nodes; determining traffic types included in the total traffic and proportions of the traffic types, making the traffic types and the proportions as attribute values of traffic type attributes of the edges for the corresponding nodes; and determining a performance requirement for the traffic between the two network element nodes as an attribute value of a traffic performance attribute of the edge for the corresponding nodes. When resource scheduling is carried out on the business network, resources which meet the network traffic requirements of the business network can be determined from the current distributable physical network resources and are distributed to the business network according to a network traffic requirement model. A problem of unreasonable description of the network traffic in the prior art is solved. The invention relates to the technical field of network communication.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a service network flow modeling method, a network resource scheduling method and a network element. Background technique [0002] A service network refers to a logical network composed of basic network devices (routers, switches, etc.) combined with service endpoints that provide services. For example, there are several WWW servers (or virtual machines), middleware servers (or virtual machines), and database servers (or virtual machines) in a business network, which are distributed in the same or different physical locations and are implemented through network infrastructure equipment. Connection to provide users with data business services. Therefore, the service network can also be understood as an overlay network (Overlay Network) superimposed on the physical network. [0003] Network traffic characteristics are the basis for high performance network planning, ...
