摘要
As a novel network architecture, software‐defined networking (SDN) separates the control plane from the data plane through the thought of centralized control and realizes flexible allocation of network resources on demand. While information‐centric networking (ICN) replaces the host‐centric TCP/IP network, and the router has the function of data storage and forwarding. With the growing trend of globalization, English translation has attracted much attention. This paper pays attention to efficient English translation in software‐defined ICN (SDICN). The translation efficiency cannot be ensured when multiple translation requests are made simultaneously in SDICN. Therefore, this paper studies deployment strategy of multi‐controllers in SDICN. The experimental results show that the proposed strategy outperforms in controller load, packet loss rate and latency, which ensures the efficiency of English translation.(#br)This paper uses SDICN system architecture based on edge caching. The English corpus content is cached by edge nodes, and the operation logic of the whole system is centrally controlled by SDN controller. Corpus content caching is independent of data interchange, which is conducive to the expansion and upgrading of interchange nodes and cache nodes respectively. Translation request routing and data caching are centrally controlled by the controller software based on the global view, which realizes the optimal scheduling of resources and flexible strategy management.
