The paper analyses the national defense scientific research " s decision - making phase, execution phase, application phase, the source is found out that asymmetric information come into being from, how does the asymmetric information affect the resource " s configure efficiency of national defense scientific research, discusses how the manager design the management system of national defense scientific research to on condition that the information is asymmetric, to settle or weaken the disadvantage influence of the resource " s configure efficiency of nat ional defense scientific research that is aroused by the asymmetry - information
一般來講，一個完整的國防科研管理流程一般分為決策、執行、運用三個階段，本文通過對這三個階段的分析，找出每個階段信息不對稱產生的根源，明確信息不對稱是如何影響國防科研投資配置效率的，在理論上論證了在信息不對稱條件下，如何設計科研管理體制來解決或者減弱信息不對稱對國防科研投資配置效率的不利影響。 -
It is conformed to the h. 323v4 and relevant national standards and ensures interoperability. besides the functions specified in h. 323, such as address translation, admissions control, zone management, call management and bandwidth control, it can satisfied with the requirements defined by users, such as web management, dynamic modification of running parameters, nat environment and fees calculation

To the issues that ipsec ca n ' t work with nat and multicast very smoothly and ipsec could n ' t also solve qos problem, combined with the national high - tech project of 863, the author has put forward the following viewpoints in the research of the security architecture model of ip layer : as to ipsec ' s working with nat, the author has proposed a scheme of using udp encapsulation along with configuring ipsec tunnel by dhcp and substituting ah with esp null encapsulation ; as to ipsec ' s working with the multicast, the author has proposed that combined with key management using complete binary tree, ipsec security process using espv3 and ahv2 can cooperate with multicast smoothly in multicast environments ; as to solving qos, the author has proposed a scheme of using two - level classifying and two - level scheduling with encryption scheduler and forwarding scheduler. the author has pointed out that combining ipsec with pki can make ipsec more flexible and more practical. based on the previous researches, the author has made an analysis of security risks of ip layer
在ip層安全體系結構模型研究中，針對ipsec在與組播、 nat協同工作等方面存在的問題以及ipsec不能很好解決qos等方面的問題，作者結合國家863高技術項目的研究提出了解決方案：在nat協同工作方面作者提出了採用udp封裝、配合使用dhcp配置ipsec隧道並用espnull封裝代替ah的方案；在與組播協同工作方面作者提出了基於espv3和ahv2的ipsec組播安全處理以及基於完全二又樹的組播密鑰管理的方案；在解決qos問題方面作者提出了採用分類器1和分類器2的兩級分類以及具有加密調度器和轉發調度器的兩級調度的技術方案；同時作者提出了ipsec與pki技術緊密結合，能使ipsec安全通信更加靈活和方便實用。
