Method for adaptively adjusting lines in unstable multi-line scene and storage medium

Abstract

The invention provides a method for adaptively adjusting a line in an unstable multi-line scene and a storage medium. The method comprises the following steps: defining two layers of marking rules on an OUTPUT chain of iptables, wherein the two layers of marking rules comprise setting a first rule corresponding to a first layer of mark of the line and setting a second rule corresponding to a second layer of mark of the line; after a first rule action is executed, an available line is selected and an fwmark is marked on the data packet, a second rule action is executed, a mapping relation is established between an available line mark and an actually available physical line mark, and a second fwmark is marked on the data packet; a program is set at an edge node to periodically execute adaptive logic, send a data packet to detect the availability of each physical line, select an available line when executing a first rule action, and select an actually available physical line when executing a second rule action, so as to adjust the pairing of the available line and the actually available physical line. Therefore, the dropped line can be automatically avoided after a part of the line of the network is dropped, and the connection of a new outbound station can be ensured on the premise that the existing network connection is not interrupted. Therefore, the problem of network obstruction of the upper-layer application is eliminated.

Description

technical field [0001] The invention relates to a network technology of edge computing, in particular to a method and a storage medium for adaptively adjusting lines in an unstable multi-line scenario. Background technique [0002] In traditional cloud computing scenarios, application services are mainly run on servers in data centers with relatively stable networks, which can run trouble-free for a long time, and their connectivity and reliability can be guaranteed. There is a corresponding alarm mechanism to notify the operation and maintenance personnel to deal with and repair in time. [0003] In addition, the network of the data center server is relatively simple. Usually, the server only has a unique network card to communicate with the external network, so it will not face complex routing rule configuration and dynamic routing adjustment. [0004] Edge Computing: Edge computing is to migrate part of the computing load to the edge location closer to the data source, i...

[0011] 2) Instability: Edge nodes use home broadband to form a network to provide external services. Home broadband is usually unstable. Usually home bandwidth is accessed through the operator's PPPoE service, and access to the Internet needs to be dialed through PPPoE

However, in the actual test, it is found that it will lead to redialing of the line or reconfiguration of routing rules, which will cause the disconnection of the existing connection, so the application service of the upper layer will be affected, resulting in frustration of user experience
