Embodiment 1

[0070] A bypass method for tunnel traffic in an embodiment of the present invention is as follows: figure 2 As shown, the method includes the following steps:

[0071] Step s201, preset bypass conditions. In this embodiment, it specifically includes the following settings: specify the head node and tail node of the IP physical link segment to be monitored; set the type and threshold of the bandwidth utilization of the IP physical link; set the tunnel to be adjusted and need to match Tunnel conditions or traffic conditions. In this embodiment, the network maintenance personnel store the set information in a custom bypass template.

[0072] Step s202, collecting IP physical link traffic and tunnel traffic of the SDN device.

[0073] Step s203, making statistics on the collected traffic. In this embodiment, the process includes: counting the peak utilization rate of the IP physical link / tunnel bandwidth within a preset time, and / or counting the average utilization rate of th...

Embodiment 3

[0087] In the specific implementation of the present invention, a cooperative SDN controller is deployed in the SDN network organization framework of IP+optical integration, which includes the functions of the IP SDN controller and the optical SDN controller, and can coordinately manage the IP device and the optical device. The collaborative controller communicates with SDN network devices through Netconf or other protocols, including IP devices and optical devices, such as Figure 4 shown. Through the planning tool APP of the present invention, network maintenance personnel only need to customize the bypass policy template, and the cooperative SDN controller will automatically bypass all traffic of MPLS TE tunnels that meet the self-defined conditions from the IP layer to the optical layer according to the scheme defined in the template. Or bypass part of the service traffic carried by the MPLS TE tunnel to the optical layer.

[0088] refer to Figure 4Compared with the tra...

Abstract

The invention discloses a tunnel flow bypassing method. The method comprises the steps of collecting an IP physical link flow and a tunnel flow of an SDN device; performing statistics on the collectedflow; according to the statistic flow data, determining whether the physical link flow and the tunnel flow meet a preset bypassing condition; and if the physical link flow and the tunnel flow meet the preset bypassing condition, bypassing qualified tunnel flow to an optical layer. The invention further discloses a tunnel flow bypassing apparatus. Through adoption of the tunnel flow bypassing method and apparatus, flow information of the IP physical link and the tunnel is collected and analyzed automatically, when the preset bypassing condition is met, qualified tunnel traffic is bypassed to the optical layer from an IP layer automatically. The method and apparatus are easy to use, in an IP+ optical network hybrid deployment-based networking architecture, network flow is optimized more efficiently, and the maintenance cost is lowered.

Description

technical field [0001] The present invention relates to the technical field of network application, in particular to a kind of MPLS (Multiple Protocol Label Switching, multi-protocol label switching technology) TE (TRAFFIC ENGINEERING, traffic engineering) tunnel flow based on SDN (Soft Defined Network, software defined network) from IP ( A method and device for automatically bypassing (bypassing) an Internet Protocol (Internetwork Interconnection Protocol) layer to an optical layer. Background technique [0002] The hybrid deployment of IP+optical networks meets some transmission requirements such as high speed and large bandwidth of IP services. Generally, the bandwidth of physical links between IP devices is much smaller than that of links between optical devices. In the traditional network organization structure, the IP network and the optical network deploy their own independent NMS (NETWORK MANAGEMENT STYTEM, network management system). proprietary network, such as f...
