Embodiment Construction
[0033] 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 some of the embodiments of the present invention, but not all of them. 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.
[0034] For ease of understanding, first combine figure 1 to briefly introduce the scenario of service flow forwarding based on virtual network elements. As mentioned above, the service flow forwarding system using virtualization technology is presented to users in the form of virtual network elements, see figure 1 , the service flow sequentially passes through virtual network element A and virtual network element B in the network, wherein each virtual...

The invention discloses a redirection method and device of a service flow forwarding path, and a service flow forwarding system. The method includes: determining a redirection parameter of a virtual network element through which the service flow passes, and the virtual network element includes a plurality of physical network elements ; According to the topology relationship of the physical network elements in the virtual network element, a redirection path for forwarding the service flow is established between the incoming interface of the starting physical network element and the outgoing interface of the last physical network element; generating the Tunnel forwarding information of the redirection path; send the corresponding packet labels to the physical network elements on the redirection path, so that the physical network elements on the redirection path forward the service flow on the redirection path in tunnel mode message. The embodiment of the present invention simplifies the redirection process of the forwarding path of the service flow.
Description
technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a method and device for redirecting a service flow forwarding path, and a service flow forwarding system. Background technique [0002] With the development of network technology, network virtualization and network centralized control are paid more and more attention and are widely used. Virtualization can be understood as a resource management technology that abstracts and converts various physical resources of a computer, such as servers, networks, memory, and storage, and presents them after conversion, which can break the inseparable relationship between physical structure and function. barriers, allowing users to apply these resources in a better way than the original configuration, without being too limited by the physical hardware. [0003] In a network using the virtualization technology, service flow forwarding is presented to users in the form of...
