This text analyzes the network system structure in the process of IPv4 transferring toward IPv6,combining the present condition of the university campus network and turning into the process toward IPv6,putting forward a project in campus network transferring into IPv6.
In the light of the demand on enterprise's network information security,this paper constructs the framework and model of the network information security system of enterprise,and works out the design of the general scheme and several design schemes of typical application information security system.
Introduce the B/S-mode solution using SVG,JavaScript,XML-RPC,JSP and Java. The solution mainly resolves those problems:corresponding nodes and lines between SVG elements;
This paper introduces the basic principle of IPSec and NAT at first, then based on the analysis of IPSec-NAT compatibilities, gives the solution in which IPSec packet is encapsulated by UDP.
In analyzes the IP address embezzlement method in the foundation,from TCP/The IP different level proposed the corresponding guard measure,and gives one kind of more ideal solution and the realization method.
We use the decomposition of a group into double cosets and a graph theoretic indexing scheme to derive algorithms that generalize the Cooley-Tukey FFT to arbitrary finite group.
The new wavelets used in [23] were designed from the Loop scheme by using ideas and methods of [26, 27], where orthogonal wavelets with exponential decay and pre-wavelets with compact support were constructed.
Based on the methods of landscape ecology and ecological planning, this paper develops a zoning project of ecosystem functions suitable for various environments.
We concluded that the conversion project from croplands to forests and grasslands based on scientific principles is very important in the formation of carbon sinks for reducing greenhouse effects.
The theory is applied to the case of cubic hypersurfaces, which is the one most relevant to special geometry, obtaining the solution of the two classification problems and the description of the corresponding homogeneous special K?hler manifolds.
A necessary and sufficient geometric condition on the growth of the boundary of approximate tiles is reduced to a problem in Fourier analysis that is shown to have an elegant simple solution in dimension one.
Indeed, if the coefficients of L are in $W^{1,2}\cap L^{\infty},$ then L can be rewritten in divergence form for which the notion of a "weak" solution can be applied.
