Network security resource distributing method based on level bidding mechanism

Abstract

The invention discloses a network security resource distributing method based on a level bidding mechanism. The network security resource distributing method based on the level bidding mechanism comprises the following steps: collecting available bandwidth resources in a network, wherein the bandwidth resources are total flow bandwidth of wireless frequency resources in a heterogeneous network; collecting security resource service application of user equipment; distributing network safety resources by using a bacteria foraging optimization algorithm; distributing bacteria into swimming bacteria and rotating bacteria according to movement modes; calculating fitness values of the bacteria, and storing the current fitness values of the bacteria as the most suitable value; searching each bacterium at an original position and calculating a fitness value at a new position; if the fitness value of bacterium at the new position is greater than that of the bacterium at the original position, the original position is replaced; if searching times reach a threshold value, randomly generating a new position; if the searching times are smaller than or equal to the threshold value, carrying out a next step; recording the position where the fitness value is maximum and a corresponding fitness function value; and repeating for multiple times to obtain the distributed resource maximum value of network security resources.

Description

technical field [0001] The invention belongs to the technical field of computer networks, in particular to a method for allocating network security resources based on a hierarchical bidding mechanism. Background technique [0002] With the increasing complexity of the network, there is an ownership structure. This means that traditional models and secure resource exchanges between original owners and end users using allocation mechanisms are no longer always relevant. There are more and more middlemen, and operators buy the network security resources of the original owners and sell them to end users. Although middlemen play an important role in matching supply and demand in urban distribution channels, they also lead to inefficient allocation of network security resources. [0003] Consider bandwidth allocation schemes. Network bandwidth is mainly owned by Tier 1 ISPs (Internet Service Providers), and then allocated to Tier 2 ISPs. Tier 2 ISPs are further assigned to Tie...
