基于订阅推送的NDN实时通信机制
Subscription push based real-time communication mechanism for NDN
摘要
Abstract
The study focused on the real-time communication mechanism of the promising Internet architecture of named data networking ( NDN) , and pointed out that NDN users obtain contents by sending out request messages, while for real-time communications such as instant chatting or monitoring Internet of things, the synchronization of the re-quest rate of users and the data production rate is difficult to realize and the needs of real-time applications are una-ble to meet when using the conventional user-driven pull mode for data requiring because of data generation' s ab-ruptness and randomness as well as the time delay of data receiving.For the purpose of reducing the data response delay, the study presented a subscription-push-based real-time communication mechanism on the basis of unmodify-ing conventional NDN routing and caching mechanisms.Under the new mechanism, the subscription information is added into NDN routers in advance, and later thereal-time producercould pushdata to the subscriber immediately. The experimental results show that this new mechanism can greatly reduce the reception delay compared with the original NDN design.关键词
