Example Embodiment

[0041] Example 1

[0042] Such as figure 1 As shown, the method for guaranteeing critical network services provided by Embodiment 1 of the present invention specifically includes:

[0043] S01. Monitor the CPU load, obtain the current CPU soft interrupt occupancy rate, and determine whether it is greater than the upper threshold of the soft interrupt occupancy rate, if yes, perform step S02, otherwise repeat step S01;

[0044] Monitor the CPU load and obtain the CPU soft interrupt occupancy rate once every second. After n seconds, calculate the average value to get the soft interrupt occupancy rate per second, which is the current CPU soft interrupt occupancy rate, and judge whether the soft interrupt occupancy rate is If the upper threshold of the soft interrupt occupancy rate is exceeded, step S02 is executed if it exceeds, and step S01 is repeated if it does not exceed.

[0045] S02: Calculate the current packet loss threshold according to the number of currently received data pack...

Abstract

The invention discloses a method and a device for guaranteeing key businesses of networks. The method and the device have the advantages that dynamic update of packet loss threshold values is achievedby monitoring a CPU (central processing unit) software interrupt occupancy rate, and dynamic and selective package loss is performed according to the current packet loss threshold values and the quantity and the type of received data packets, so that the problem that normal operation of the key businesses cannot be guaranteed due to network congestion caused by full load of CPUs in the prior artis solved, dynamically-adjustable selective packet loss is realized, and normal operation of the key businesses under different application occasions is guaranteed sufficiently.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to a method and device for guaranteeing key network services. Background technique [0002] In a common network environment, the overload of the network will cause the CPU load of the router to be fully loaded, which will seriously affect the scheduling of upper-layer applications, and sometimes cause some applications to be basically unavailable, the timing is completely uncontrollable, and even flow control occurs. Problems such as failure to take effect will not guarantee the normal operation of key services, and there will be situations such as network forwarding freezes, network service interruptions, and slow key business forwarding. [0003] The existing technology also adopts measures such as monitoring CPU and packet loss to control traffic and network congestion. However, the set packet loss conditions are static, rather than dynamically changing acc...
