【摘要】：內(nèi)容命名網(wǎng)絡(luò)(NDN)作為ICN的實(shí)例系統(tǒng),以其區(qū)別于傳統(tǒng)IP網(wǎng)絡(luò)的獨(dú)特體系結(jié)構(gòu)在近些年受到了研究界的普遍關(guān)注,NDN舍棄了IP網(wǎng)絡(luò)點(diǎn)到點(diǎn)的傳輸方式,設(shè)計(jì)了基于內(nèi)容名字的尋址方式,使得內(nèi)容的提供者由集中式一點(diǎn)變?yōu)榉稚⑹降亩帱c(diǎn),大幅提高了數(shù)據(jù)信息的利用率。將研究的重點(diǎn)放在NDN路由節(jié)點(diǎn)的轉(zhuǎn)發(fā)環(huán)節(jié),提出并實(shí)現(xiàn)了一種新的基于歷史訪問記錄的轉(zhuǎn)發(fā)策略HRF,使得數(shù)據(jù)請(qǐng)求者能夠發(fā)現(xiàn)本地的鄰居節(jié)點(diǎn)是否持有請(qǐng)求者所需的內(nèi)容,從而從本地網(wǎng)絡(luò)高效快速地獲取所需數(shù)據(jù),并通過實(shí)驗(yàn)驗(yàn)證了HRF策略的可行性和有效性。
[Abstract]:As an example system of ICN, the content named Network (NDN) has attracted much attention in recent years because of its unique architecture, which is different from the traditional IP network. In recent years, it has been widely concerned that NDN has abandoned the point-to-point transmission mode of IP network.A content-based addressing method is designed to change the content provider from a centralized point to a decentralized multi-point, which greatly improves the utilization rate of data information.Focusing on the forwarding of NDN routing nodes, this paper proposes and implements a new forwarding strategy based on historical access records, which enables the data requester to find out whether the local neighbor node holds the content required by the requestor.In order to obtain the required data efficiently and quickly from the local network, the feasibility and effectiveness of the HRF strategy are verified by experiments.
