Problems solved by technology
In the SDN scenario provided by the present invention, the VNI based on VXLAN distinguishes services, divides service levels, and then implements SR-TE (Segment Routing Traffic Engineering, segment routing-based traffic Engineering) tunnel, and use the SDN controller to calculate the forwarding path that meets the business requirements for the SR-TE tunnel. This technical solution can effectively solve the difficulty that the VxLAN network currently encounters that the forwarding path cannot be controlled and visualized. Different SR-TE tunnels and intelligent path algorithms can automatically match service requirements, so that service applications drive network deployment and simplify network deployment

Embodiment Construction
[0038] 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 making creative efforts belong to the protection scope of the present invention.
[0039] The basic idea of the present invention can be summarized as in the SDN scenario, classify service levels based on different tenant services, and the SDN controller can create tunnels with different forwarding paths, so that different tenant services can take different tunnel forwarding paths, and different tenant services can be implemented. Differentiated service capabilities for business; this patent can combine network conditions, traffic character...

The invention discloses a data forwarding method and device and a computer readable storage medium, belongs to the field of communication, and is applied to an SDN scene, and the data forwarding method comprises the steps that an SDN controller creates a plurality of SRTE tunnels according to different service levels of tenants, wherein the service level is set by the SDN controller; the SDN controller issues a forwarding strategy to a forwarding device, wherein the forwarding device matches different tenant services with corresponding SRTE tunnels according to the forwarding strategy and forwards messages; according to the forwarding method, functions of an existing forwarding device and an SDN controller are expanded, hardware functions of the forwarding device are not involved, and theforwarding device of a current network can be supported only by software upgrading; and different tunnel forwarding paths are routed based on different tenant businesses, so that differentiated service capabilities of different tenant businesses can be realized.
Description
technical field [0001] The present invention relates to the communication field, in particular to a data forwarding method, device and computer-readable storage medium applied in an SDN scenario. Background technique [0002] With the development of SDN and NFV (Network Function Virtualization, network function virtualization) technology, the virtualized data center technology has attracted extensive attention in the industry, and various application scenarios emerge in endlessly. Multi-tenant physical data centers realize three-layer interconnection through the IP bearer network. On the premise of introducing an SDN controller, a VXLAN (Virtual eXtensible LANs) tunnel can be dynamically established between the egress gateways of the two data centers, thereby realizing a network based on The effect of the large Layer 2 interconnection of the IP bearer network is similar to that of the MPLS VPN technology. By making reasonable use of the VXLAN tunnel-based control plane (suc...
