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 be combined with the accompanying drawings in the embodiments of the present invention, the technical solution in the embodiments of the present invention will be described clearly and completely, it is clear that the embodiments described are only a part of the embodiment of the present invention, not all embodiments. Based on embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work, are within the scope of protection of the present invention.

[0039]The basic idea of the present invention can be summarized as in the SDN scenario, based on different tenant services to divide the service level, and the SDN controller can create different forwarding path tunnels, to achieve different tenant services to take different tunnel forwarding paths, can achieve different tenant services differentiated service capabilities; This patent can combine network conditions, traffic characteris...

Abstract

The invention discloses a data forwarding method, device and computer-readable storage medium, which belong to the communication field and are applied in an SDN scenario, wherein the data forwarding method includes an SDN controller creating multiple SR-TE tunnels according to different service levels of tenants ; Wherein, the service level is set by the SDN controller; the SDN controller sends a forwarding policy to the forwarding device; wherein the forwarding device links different tenant services with the corresponding SR-TE according to the forwarding policy The tunnel matches and forwards the message; this forwarding method is an extension of the function of the existing forwarding device and SDN controller, and does not involve the hardware function of the forwarding device. The forwarding device of the current network only needs a software upgrade to support it; based on different tenant services Different tunnel forwarding paths can be used to realize differentiated service capabilities for different tenant services.

Description

Technical field [0001] The present invention relates to the field of communications, particularly to a data forwarding method applied to the SDN scenario, a device, and a computer-readable storage medium. Background [0002] With the development of SDN and NFV (Network Function Virtualization) technology, virtualized data center technology has attracted wide attention from the industry, and various application scenarios have emerged in an endless stream. Under the premise of introducing the SDN controller, the VXLAN (Virtual eXtensible LANs) tunnel can be dynamically established between the egress gateways of the two data centers, so as to realize the large layer two interconnection based on the IP bearer network, which is similar to MPLS VPN technology. By making proper use of the control plane based on VXLAN tunnels (such as EVPN, Ethernet Virtual Private Network), the egress gateway of the data center can achieve a role similar to that of the PE device in the MPLS VPN network,...
