Embodiment Construction

[0046] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0047] figure 1 It is a schematic diagram of the existing system architecture 100 . The system architecture 100 can be understood as a telecommunication backbone network. figure 1 The illustrated telecommunication backbone network is generally planned, constructed and managed in layers according to an internet protocol (IP) network and an optical network. The layer where the IP network is located may be called the IP layer, and the layer where the optical network is located may be called the optical layer. like figure 1 As shown, the IP network includes multiple IP network elements, the optical layer may include multiple optical network elements, and the IP network elements and the optical network elements are connected through cross-layer links.

[0048] Exemplarily, the above-mentioned IP network elements may be switches, routers, gateway GPRS ...

Abstract

The invention provides a network control method, device and system, and the method, device and system can achieve the unified management of an IP network and an optical network, thereby reasonably controlling the use of resources of a whole network. The method comprises the steps of: obtaining first link state information and second link state information, wherein the first link state informationis used for representing the link state of an internet protocol IP network, and the second link state information is used for representing the link state of an optical network; determining third linkstate information according to the first link state information and the second link state information, the third link state information comprising a link state of the IP network and a link state of the optical network; and calculating a path according to the third link state information.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a network control method, apparatus and system in the field of communications. Background technique [0002] The telecommunication backbone network is generally planned, constructed and managed in layers according to the Internet Protocol (IP) network and the optical network. The layer where the IP network is located may be called the IP layer, and the layer where the optical network is located may be called the optical layer. For a long time, the IP layer and the optical layer have adopted different technical routes, and have developed independently for a long time without perceiving each other. The IP layer can be used as the load of the optical layer; the optical layer can be used as the pipeline of the IP layer. Software-defined networking (SDN) still inherits the traditional layering idea, and builds IP network controller and optical network controller, which c...
