point-to-point links and edge-type links can go to the forwarding state immediately 點(diǎn)對(duì)點(diǎn)連結(jié)及端點(diǎn)類型連結(jié)能立即成為轉(zhuǎn)送狀態(tài)。
but the number of forwarding states becomes huge in routers when there are a large number of multicast groups in the network, which may cause explosions of state information and control information 組播在數(shù)據(jù)轉(zhuǎn)發(fā)上有明顯的優(yōu)勢(shì),但是當(dāng)網(wǎng)絡(luò)中的組播組很多時(shí),轉(zhuǎn)發(fā)狀態(tài)大大增加,管理組播組需要消耗大量的資源和控制開銷。
secondly, unlike previous approaches that concentrated on reducing forwarding states to improve multicast scalability after constructing multicast trees, our approach is to include forwarding state scalability as one of the optimal objectives when constructing new multicast trees . that is, we make the underlying routing algorithms aware of the scalability requirement . this is scalability-aware approach can be applied to many exiting multicast state reduction methods 第二,針對(duì)現(xiàn)有多播可擴(kuò)展性方法的不足(現(xiàn)有的方法大都在已有多播路由的基礎(chǔ)上進(jìn)行改進(jìn),效率較低),將多播可擴(kuò)展性作為一個(gè)最優(yōu)化目標(biāo)引入到多播路由算法的設(shè)計(jì)中,有效地提高了多種多播可擴(kuò)展性方法的效率,是多播可擴(kuò)展性研究的一個(gè)新思路。

the thesis introduces the basic meanings of state-owned assets and relative questions, analyses the problems in present state-owned assets management in china . based on the analysis and reference of foreign state-owned assets management models, puts forward state-owned assets management models which we can make choice and standard of choice, structure state-owned assets management models of our country and it's realizing ways; and it analyses the concrete evidence, based on the comparative analysis of regional government state-owned assets management models, puts forward state-owned assets management models of changchun city 論文闡述了國(guó)有資產(chǎn)的涵義及相關(guān)理論問(wèn)題,通過(guò)對(duì)我國(guó)國(guó)有資產(chǎn)的歷史回顧與現(xiàn)狀分析,指出了當(dāng)前我國(guó)國(guó)有資產(chǎn)管理中存在的問(wèn)題;并在分析和借鑒國(guó)外國(guó)有資產(chǎn)管理模式的基礎(chǔ)上,提出了我國(guó)國(guó)有資產(chǎn)管理可供選擇的模式及選擇標(biāo)準(zhǔn),構(gòu)建了我國(guó)三層次的國(guó)有資產(chǎn)管理的目標(biāo)模式及其實(shí)施途徑;并且進(jìn)行了實(shí)證研究,在比較分析我國(guó)地方政府國(guó)有資產(chǎn)管理模式的基礎(chǔ)上,提出了長(zhǎng)春市的國(guó)有資產(chǎn)管理模式。
