A kind of SDN multi-thread timing control method, system, device and readable storage medium

Abstract

The present application discloses an SDN multi-thread timing control method, system, device and computer-readable storage medium, comprising: receiving a network element device IP binding request sent by a virtual router; judging an IP corresponding to the network element device IP binding request Whether the binding tag semaphore of the address is in the unbound state; if the binding tag semaphore is in the unbound state, the IP address is allocated to the network element device recorded in the IP binding request of the network element device to complete the binding; If the fixed marked semaphore is not in the unbound state, continue to judge whether the bound marked semaphore of the IP address is in the unbound state; this application adds a binding marked semaphore for the IP address in advance for processing the IP binding of the network element device. Determine the binding state of the IP address when requesting, and do not perform an incorrect binding operation when the binding flag semaphore is not in the unbound state, and perform the binding operation until the binding flag semaphore is in the unbound state to ensure that the network element equipment is in the unbound state. The IP binding request can be effectively executed, which solves the timing problem.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to a method, system, device and computer-readable storage medium for SDN multi-thread timing control. Background technique [0002] SDN (Software Defined Networks, Software Defined Networks) is a new type of network innovation architecture, which realizes flexible control of network traffic by separating the control plane and the data plane. The SDN controller manages multiple network element devices to realize automatic network deployment. When the SDN controller manages multiple network element devices, in order to improve the operating efficiency of the software system, multi-thread concurrent processing is usually used for configuration processing. [0003] The SDN controller system creates a thread for each network element device. When a virtual router binds an NE device, the SDN controller system sends a NE Bind Router message to the NE thread, and the NE thread receive...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, when there is a timing problem in the response sequence between threads, the binding request will be processed before the unbinding request. Since the IP address has been bound, the IP address cannot be assigned to the new network element device, resulting in The newly bound NE thread did not deliver the IP address to the new NE device, resulting in unavailable functions
