Firewalls play a vitally important role to network security. Packet filtering in firewall either accepts or denies packets based upon set of pre-defined rules called policy. Management policy is boring task and always prone error. There have been lot analysis methods for anomalies detection IPv4 But, the reason enormous address space, these could not be used deal with IPv6 directly, low effectiveness. In this work, we propose method by using formal that can analyze inclusion relations...

<abstract><p>This paper elucidates that the AIDS/HIV incidence rate differences exist among different population and regions, especially old college students. Due to effect of age, AIDS peak in males aged 20–35 years 50 both Chongqing Shenzhen, increasing spread was higher than females under period effect. In local over 40, below whole age groups are predicted increase sharply future six years, while females, rates 40-year-old were as well. The homosexually transmitted patients...

Varicella (chickenpox) is highly contagious among children and frequently breaks out in schools. In this study, we developed a dynamic compartment model to explore the optimal schedule for varicella vaccination Jiangsu Province, China. A susceptible-infected-recovered (SIR) was proposed simulate transmission of different age groups. The basic reproduction number computed by kinetic model, impact three prevention factors assessed through global sensitivity analysis. Finally, effect various...

After data processing, 12469 (HIV HBV, 1033; HIV, 11436) left further analysis, including 7849 4620 transmission. Univariate logistic regression was used to select variables significant P value odds ratio multivariable...

Packet filtering in firewall either accepts or denies network packets based upon a set of pre-defined filters called policy. Firewall policy is designed under the instruction security A generic document that outlines needs for computer access permissions. And it determines how are designed. If inconsistencies, such as redundant filters, insufficient contradict exist between and policy, could not filter exactly, protected by will be affected. To resolve this problem, we propose an...

Firewalls have been a very important secure tool to protect networks against attacks, which usually filter the unauthorized traffic entering secured network. The packet filtering based on predefined collection of ordered rules. Along with IPv6 protocol is widely used, and security issues comes it. Firewall for network, as an element network security, it will be not able packets correctly if there are conflicts that caused by same matching two or more In addition, new kind firewall time...

Snort is the most popular Intrusion Detection Systems (IDS). It will generate alert messages when an arrival packet matches some of pre-defined rules. has problems as follows: it tries matching for all rules even never in case other rules, and provides contradictory redundant a set erroneous poorly-organized given. This paper proposes method characterizing relations between towards solutions above problems. The proposed calculates topological based on theory.

Available bandwidth estimation is useful for route selection in overlay networks, QoS, and traffic engineer-ing. Many measurement algorithms, such as Pathload, Pathchar, Packet Transmission Rate (PTR) method, etc. have been proposed. PTR method sends a sequence of packet trains to characterize the interac-tion between probing packets competing traffic, uses average rate train an estimate available bandwidth. However, this algorithm does not fully consider situation that detection lost...
