Abstract

An embodiment of the invention provides a method for transmitting virtual traffic based on an artificial network, which comprises the following steps of: in response to the virtual traffic to be transmitted matching a corresponding intention routing rule at a source node, packaging the virtual traffic at each subsequent node in an intention routing path of the virtual traffic to be transmitted, transmitting the packaged virtual traffic to a next node according to the intention routing path, and unpackaging the virtual traffic until the virtual traffic to be transmitted reaches a destination node in the intention routing path, wherein the intention routing rule is generated according to the intention routing path of the virtual traffic to be transmitted and is deployed on tanhe intention routing data module, and the intention routing path of the virtual traffic to be transmitted comprises key nodes in a hop-by-hop routing path of the virtual traffic to be transmitted. According to the method provided by the embodiment of the invention, unnecessary packaging and unpackaging steps in the traffic transmission process can be greatly reduced, and the traffic transmission performance is improved while the routing function of the artificial network is maintained.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a method and system for encapsulating, decapsulating and transmitting virtual traffic based on a simulated network. Background technique [0002] At present, the large-scale simulation network of semi-materialization usually uses the overlay (Overlay) network virtualization technology to simulate a variety of real networks. Overlay refers to a virtualization technology mode that is superimposed on the network architecture. Its general framework is to build a virtual network on top of the existing physical network without making large-scale modifications to the basic network, so as to realize the bearing of applications on the network, so that the upper-layer applications are only related to the virtual network and can communicate with other networks. Separation of network services. [0003] The devices in the simulated network (including terminals and network devices) are usual...
