Weighted hashing could distribute appropriate flow according to enable firewall component, to improve overall efficiency. In the fault-tolerant mechanism, transition hashing table was used to record unstable connection when firewall component came into failure or came back to work, which could avoid existed connections broken due to the transformation of algorithm parameter.

加权处理根据防火墙组件的不同处理能力调度访问请求，保证处理能力强的防火墙组件处理更多的访问流量，提高了系统的整体效率；容错机制在防火墙组件失效或恢复正常时利用基于连接调度的过渡散列表记录不稳定连接，避免已有连接因算法参数改变而失效。

Though comparing Canny operator and center B spline dyadic wavelet, the following conclusion is proven in this dissertation: a Center B spline function has tight support and Canny operator hasn't. b Center B spline function asymptotic convergence to Gaussian function and the derivative of Center B spline function asymptotic convergence to Canny operator. c The derivative of fourth order center spline B function is more suitable as a optimal edge detector than Canny operator. d Center B spline function can balance the smoothing and approximation of original data, and the fourth center B spline function is the only optimal solution of two order smoothing problem. e The error between the valve of time-frequency uncertainty of the fourth center B spline function and the lower bound of time-frequency uncertainty does not exceed 0.143% of the lower bound. f The derivative of center spline B function can construct a stability dyadic wavelet and can give a fast algorithm for multiscale edge detection, but Canny operator can do neither.

作者给出了Canny算子与中心B样条二进小波严格的比较证明，得出如下结论：a中心B样条函数具有紧支集，Canny算子不具有紧支集。b中心B样条函数的极限收敛于高斯函数，中心B样条函数的导数收敛于Canny算子。c四阶中心B样条函数的导数比Canny算子更接近最佳边缘检测滤波器。d中心B样条函数比高斯函数更能兼顾对原函数平滑和逼近的折中要求，并且四阶中心B样条函数是二阶逼近问题的唯一最优解。e四阶中心B样条函数的时频测不准关系值与时频测不准关系下界的逼近误差不超过0.143％。f中心B样条函数的导数可以构成稳定的二进小波，存在快速的多尺度算法；而Canny算子不构成稳定的二进小波，无法给出快速的多尺度算法。

hashing function：杂凑函数

此种函数,一般称之为杂凑函数(Hashing function)或键值对应位址转换(key to address transformation). 对於有限的储存空间,能够有效使用且在加入或删除时也能快的完成,利用杂凑法是最适当不过了. 因为杂凑表搜寻在没有碰撞(collision)及溢位(overflow)的情况下,
