【摘要】：內容命名網絡(NDN)作為ICN的實例系統(tǒng),以其區(qū)別于傳統(tǒng)IP網絡的獨特體系結構在近些年受到了研究界的普遍關注,NDN舍棄了IP網絡點到點的傳輸方式,設計了基于內容名字的尋址方式,使得內容的提供者由集中式一點變?yōu)榉稚⑹降亩帱c,大幅提高了數據信息的利用率。將研究的重點放在NDN路由節(jié)點的轉發(fā)環(huán)節(jié),提出并實現了一種新的基于歷史訪問記錄的轉發(fā)策略HRF,使得數據請求者能夠發(fā)現本地的鄰居節(jié)點是否持有請求者所需的內容,從而從本地網絡高效快速地獲取所需數據,并通過實驗驗證了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.
