摘　　要：当前,互联网的应用模式已经从发送者驱动的点对点通信转向接收者驱动的大规模信息获取。用户通常并不关心谁发布了这些信息,以及这些信息位于何处,而仅仅关注信息本身。信息中心网络(Information Centric Network,ICN)架构顺应了这一应用模式,实现了内容生产者与内容消费者之间的解耦,内容名字与存储位置的解耦和泛在的内容之缓存。但是ICN不能高效地支持发布/定义的应用模式。为此,本文提出在ICN的主流架构之一——内容中心网络(Content Centric Network,CCN)中实现基于Push模式的内容实时推送能力。同时,为了研究CCN网络与IPv6网络的融合互通,本文在系统实现时将上述具有Push能力的CCN网络部署在IPv6边缘,并在IPv6网络中使用IPv6组播通信,实现IP网络资源的高效利用。The Internet usage has shifted from sender-driven end-to-end communication to receiver-driven large-scale content retrieval.Users usually do not care who publishes the content and where the content is located,but only care about the content itself.Information Cenctric Network adapts the shift of the network application mode.It enables the content producers and consumers to decouple from each other and unbind the content’s name with its location.What’s more,it provides built-in caches.However,since ICN is essentially a Pullbased publish/subscribe network,it can hardly efficiently support the Push-mode applications.Based on it,This paper proposes to implement push ability in Content Centric Network,which is a mainstream architecture of ICN.In addition,in order to achieve the gradual transition from ICN to IPv6 network,the CCN network with push ability is deployed at the edge of IPv6.What’more,in order to take advantage of IPv6 network as much as possible,we use IPv6 multicast technology to transmit message,which can ensure that the same message is transmitted only once on the same link.
