摘要:一种NDN和IP融合网络的内容管控方法及装置。捕获TCP/IP网络中的客户端发出的请求包;对该请求包进行应用层协议的深度报文分析,当判断该请求包是符合第一类目标站点的请求报文,则根据预先建立的命名映射表,确定替换内容的命名;根据替换内容的命名和该请求包在TCP/IP网络下所请求内容,生成NDN协议格式的兴趣包,并转发到NDN网络中;获取所述NDN协议格式的兴趣包被转发到NDN网络后所返回的NDN协议格式的数据包;将所述NDN协议格式的数据包转换成IP协议格式的数据包,并返回给所述TCP/IP网络下的客户端。本发明实现了内容粒度级别的内容管控,可以对内容进行修改或替换,再返回给用户,这在传统TCP/IP网络是无法做到的。

Abstract: The invention discloses a content management and control method and device for an NDN (Named Data Networking) and IP (Internet Protocol) fusion network. The method comprises the following steps: capturing a request packet sent by a client in a TCP (Transmission Control Protocol)/IP network; performing deep packet analysis of an application layer protocol on the request packet, and determining thename of replacement content according to a preestablished named mapping table when the request packet is judged to be a request message conforming to a first-class target site; generating an interestpacket in an NDN protocol format and forwarding the interest packet to an NDN network according to the name of the replacement content and content requested under the TCP/IP network; acquiring a datapacket in the NDN protocol format returned after the interest packet in the NDN protocol format is forwarded to the NDN network; and converting the data packet in the NDN protocol format into a data packet in an IP protocol format, and returning the data packet to the client under the TCP/IP network. Through adoption of the content management and control method and device, content management and control of a content granularity level are realized and the content can be modified or replaced and returned to a user, which is impossible in a traditional TCP/IP network.
