Embodiment Construction

[0015] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0016] figure 1 is a flow chart of a port flapping suppression method according to an embodiment of the present invention. Such as figure 1 As shown, the port flapping suppression method according to the embodiment of the present invention includes the following processing:

[0017] Step S102: regularly obtain the current oscillation status of the port, and map it as a penalty value;

[0018] Among them, the above penalty value is a value calculated by the algorithm according to the frequency of up and down events. The algorithm is required to increase according to a certain rule according to the frequency of up and down events, and decay according to a certain rule over time. For example: the pen...

Abstract

The invention discloses a method and a device for inhibiting port oscillation. The method comprises the following steps of: regularly obtaining the current oscillation state of a port and mapping to form a punishment value; judging whether the punishment value is greater than the inhibiting threshold or not, if so, setting the port to be in a failure state and reporting to an upper-layer protocol module that the port is in the failure state. The technical scheme can effectively inhibit the oscillation frequency of the port and reduce influence on the stability of a communication device and the whole network by port oscillation.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for suppressing port oscillation. Background technique [0002] In the application of communication equipment, due to various reasons (such as physical signal interference, link layer configuration errors, etc.), the port may frequently alternately appear in the connected (up) and unconnected (down, or failure) state. [0003] Frequent port flapping will cause repeated flapping of various routing protocols, Multi-Protocol Label Switching (MPLS for short), Spanning tree protocol (STP for short), and other upper-layer protocols, and will also affect the central The processor (Central processing unit, referred to as CPU) has a certain impact, which has a serious impact on equipment and networks, and may even cause some communication equipment to be paralyzed, resulting in unusable networks and affecting various network services.
