Problems solved by technology

[0003]In order to reduce the impact of monitoring on NE forwarding, NEs will impose certain restrictions on concurrent access, and the sudden change in the concurrent access of the controller to NEs may lead to exceeding the network Meta-concurrency access failure problem

Embodiment 1

[0041] Such as figure 1 As shown, this embodiment provides a system for solving the problem of limited concurrent access to network elements, and the system includes:

[0042] The first producer, the tunnel queue to be detected, the first consumer, the tunnel queue that has not obtained the detection result and the second consumer, among which,

[0043] The first producer periodically traverses the network element equipment, obtains all tunnels with the network element equipment as the source node, and adds the queried tunnels to the queue of tunnels to be detected;

[0044]The first producer is an object in the program, which is responsible for querying the tunnels to be detected, adding them to the queue of tunnels to be detected, and is an independent thread when the program is running; the first consumer is also an object in the program, responsible for receiving The tunnel in the detection tunnel queue sends detection information to the network element device, and it is ...

Embodiment 2

[0057] Based on the above system, the present application also discloses a method for solving the problem of limited concurrent access to network elements, and the method includes the following steps:

[0058] Step 1: The first producer regularly traverses the network element equipment, obtains all tunnels with the network element equipment as the source node, and adds the queried tunnels to the queue of tunnels to be detected;

[0059] Step 2: The first consumer removes a tunnel from the waitingTunnel queue of the undelivered tunnel queue each time, decrements the leftNum by one, sends the detection information of the tunnel, and adds the tunnel to the tunnel queue of unobtained results , until the tunnel queue waitingTunnel that has not delivered detection is empty or leftNum is equal to 0;

[0060] Step 3: The second consumer blocks when the tunnel queue that has not obtained the result is empty; if it is not empty, the second consumer queries the detection result of the tu...

Abstract

The invention discloses a method and system for solving the problem of network element concurrent access limitation and a computer readable storage medium, and the method comprises the steps: 1, traversing network elements one by one, querying all tunnels taking the network elements as source nodes, and adding the queried tunnels to a to-be-detected tunnel queue; 2, according to the residual concurrent number leftNum of the current equipment, removing leftNum tunnels from a to-be-detected tunnel queue, issuing detection of the tunnels to the equipment, and adding the tunnels into the tunnel queue which does not obtain a detection result; and 3, removing the tunnel with the obtained result from the tunnel queue without the obtained detection result, releasing the occupied leftNum, and storing the detection result on a controller; repeating the above steps, thereby completing the collection of the tunnel performance information on the controller, and completing the control of the concurrent access network element of the controller. Concurrent access of sudden increase of the controller to the network elements can be effectively solved, and healthy and stable operation of the controller is guaranteed.

Description

technical field [0001] The invention belongs to the field of application technology in IP backbone network and 5G bearer network, and specifically relates to the concurrency control of controller access to network elements in the SDN (Software Defined Network, software defined network) scenario. Background technique [0002] With the rapid development of the network and the emergence of 4K and VR applications, the IP backbone network, as an indispensable link connecting various services, inevitably faces new problems and challenges. Operators need to monitor various performance data of the network in real time to detect problems in time and respond to various emergencies in the network. With the increasing scale of SDN network equipment and carrying more and more services, users have put forward higher requirements for the intelligent operation and maintenance of SDN networks, including higher accuracy of monitoring data for timely detection and rapid adjustment of micro-bur...
