Embodiment Construction
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0027] In the embodiment of the present invention, the fusion of two IP backbone networks is taken as an example for illustration. In order to facilitate the distinction, the two IP backbone networks are divided into main network and subordinate network. Specifically, the subordinate network is the same as the main network. Correspondingly, the IP backbone network with relatively small performance and scale, correspondingly, the main network is an IP backbone networ...

The invention discloses an IP backbone network merging method and device, and relates to the technical field of networks. In the network convergence process, cut over without interruption of services is achieved, and cut over complexities are reduced. The method comprises the steps that any of links between a service access router and a convergence router is assigned to be a first link, and all flows of all the links between the service access router and the convergence router are adjusted to the first link; all the links except for the first link are disconnected; a second link between the service access router and a main network is built, the second link is the link between the service access router and a convergence router of the main network, and the flows on the first link are adjusted to the second link. The IP backbone network convergence method and device are mainly applied to the IP backbone network convergence process.
Description
technical field [0001] The invention relates to the field of network technology, in particular to a method and device for IP backbone network integration. Background technique [0002] Currently, the IP backbone network can be used to carry Internet leased line services and carrier-class services. In order to integrate applications based on various heterogeneous networks into one IP backbone network, a network convergence solution is proposed. For example, considering the demand for comprehensive service carrying, with the continuous development of the network and services, one IP backbone network can carry multiple services to meet the demand. If multiple services are carried by two IP backbone networks to one IP The comprehensive bearer of the backbone network requires the integration of the IP backbone network. Of course, in some cases, the positioning of the two IP backbone networks of the operator overlaps and bears similar services. At this time, network convergence i...
