Embodiment 1

[0025] Embodiment 1 is based on the background of SDN / OpenFlow environment networking, see figure 1 , where A, B, C, D, E, F, G, H are network nodes, including but not limited to switches or routers, assuming that they are OpenFlow switches for data forwarding and switching, and the control plane switches in the figure are connected A-H The control plane switch of the switch and the controller is used to transmit OpenFlow control data. The controller receives the information reported by A-H through this forwarding channel, and sends various instructions to the A-H OpenFlow switch through the OpenFlow message format. It embodies one of the construction methods of the device of the present invention.

[0026] The processing steps of the process part of embodiment 1 are as follows (the flow chart can refer to the flow chart of embodiment 1):

[0027] S101: According to OpenFlow and its extended protocol, the network node reports to the controller which evaluation capability elem...

Embodiment 2

[0036] Embodiment 2 is based on the background of non-SDN / OpenFlow traditional networking, see Figure 4 , where A, B, C, D, E, F, G, H are network nodes, including but not limited to switches or routers, which are traditional switches for data forwarding and switching, where node C is where the control module is located The switch is used to send control and forwarding information to other switches including itself. Node C receives the information reported by A-H through the in-band or out-of-band forwarding channel, and sends various instructions to the A-H switch through a customized message format. At the same time The information also embodies one of the construction methods of the device of the present invention.

[0037] The processing steps of the process part of embodiment 2 are as follows (the flow chart can refer to the flow chart of embodiment 2):

[0038] S201: The network node reports to the node where the control module is located the elements that can report t...

Embodiment 3

[0047] The processing method is the same as that in Embodiment 1, and the only difference is that the connected link is a wireless connection.

Abstract

The invention provides a method and device for achieving dynamic and intelligent routing of a data communication network. The method includes the steps that all factors having influence on performance of network communication constitute an evaluation set, an evaluation system constituted by all combinations of the factors serves as a basis for evaluating corresponding network path costs, corresponding paths are endowed with the corresponding costs, and therefore optimal paths are calculated. Intelligent control having flexibility to the network and high fine grit is provided through the method and device. Thus, intelligent routing can be conducted on cells in network communication, and dynamic and intelligent routing of the network can be flexibly achieved.

Description

technical field [0001] The invention relates to the field of network communication. Background technique [0002] The current SFP routing algorithm is relatively simple in terms of link cost data obtained, which is assigned automatically or manually. Depending on the algorithm of the link state protocol, the source of the cost can be the number of hops the packet has to traverse, the link bandwidth, the current load on the link, or even other weights added by the administrator. However, the current cost evaluation system is far from meeting the requirements of the actual network. There needs to be a method that can comprehensively consider various related factors in the network for overall unified calculation and coordination. The emergence of the current SDN / OpenFlow network technology provides conditions for the collection and calculation of various related data. By extending the OpenFlow protocol, various data that the network management cares about can be collected to t...
