Abstract

The disclosure discloses an OSPF protocol-based critical path information forwarding method, device and system, and relates to the field of IP network intelligence. The method includes: the initial OSPF node receives the OSPF signaling control information sent by the controller, the OSPF signaling control information encapsulates critical path information, and after removing the relevant information of the node in the OSPF signaling control information, the remaining OSPF signaling The control information is encapsulated in the LSA, and according to the critical path information received from the controller, the LSA is sent to the next OSPF node; the intermediate OSPF node receives the LSA sent by the previous OSPF node, and after removing the relevant information of the node, Encapsulate the remaining OSPF signaling control information in LSA, and send the LSA to the next OSPF node according to the critical path information sent by the previous OSPF node; the terminal OSPF node processes the OSPF signaling control information in the received LSA, and sends The processing results are sent to the controller. The disclosure realizes end-to-end quality assurance for key services.

Description

technical field [0001] The present disclosure relates to the field of intellectualization of IP networks, and in particular to a key path information forwarding method, device and system based on OSPF (Open Shortest Path First, Open Shortest Path First) protocol. Background technique [0002] SDN (Software Defined Network, Software Defined Network) is a new network innovation architecture and a way to realize network virtualization. Under the SDN architecture, the flexible control of network traffic is realized by separating the control plane and data plane of network equipment. However, in related technologies, end-to-end quality for key services cannot be guaranteed. Contents of the invention [0003] A technical problem to be solved in the present disclosure is to provide an OSPF protocol-based key path information forwarding method, device and system, which realize end-to-end quality assurance for key services. [0004] According to one aspect of the present disclosu...
