Problems solved by technology

But there are still some problems in two parts. First, a large amount of memory needs to be used for organization and management; second, the migration of timers needs to consume a lot of CPU resources.
The number of organizations that the device needs to manage is too large, and the CPU spends too much on timer migration

Embodiment Construction

[0028] Provides a timer scheduling method, which is suitable for timeout processing of resources such as network message information and network sessions in the current IP network environment, and uses limited hardware resources (hardware timers, memory, etc.) to achieve timer scheduling The algorithm achieves the same time complexity O(1) timer scheduling method as the FIFO (First In First Out) queue.

[0029] The organization method of the timer is very important, and the efficiency can be greatly improved through a good organization method. Analyze the organization method of the timer from the application environment. First, analyze the characteristics of the IP network environment. The application environment is that the current IP network environment is a TCP / IP 4-layer model. The function of each layer is described as follows:

[0030] Application Layer: The application layer in the TCP / IP group combines the functions of the OSI application layer, presentation layer, an...

Abstract

The invention provides a method for dispatching a timer under an IP network environment, which is a timer dispatching method applicable to overtime processing of network message information, network session and other resources under current IP network environment, and the method realizes time complexity O (1) of a timer dispatching algorithm the same as FIFO (First In First Out) queue through changing organization mode of the timer under a limited hardware resource (such as a hardware timer, a memory and the like). The method for dispatching the timer is applicable to using mode of communication network resources, so the method can be widely applied to a network equipment operation system, greatly reduces consumption of the timer on CPU resources in practical application, and improves service efficiency.

Description

technical field [0001] The invention relates to timer technology, in particular to an efficient timer scheduling method in an IP network environment. Background technique [0002] Network security equipment needs to have statistics, analysis, and control functions. First, it needs to complete the management of network message information and network session information. Take a network with only 1,000 hosts as an example: information such as the usage status of each host needs to be reflected. Generally, the IP protocol is used in the network, and the connection methods include: TCP, UDP, and ICMP. The state of the network communication session needs to be maintained, and at least 70 to 80 sessions are required to ensure the normal use of the host. It includes a large number of communication connections to ensure the normal use of the network; each user needs to use network resources and network information, such as Web browsing, and also needs to establish a large amount of...
