Example Embodiment

[0033] The specific embodiments of the present invention will be further described below in conjunction with the drawings and embodiments. The following examples are only used to illustrate the present invention, but not to limit the scope of the present invention.

[0034] In this embodiment, a method for implementing the bottom layer of the content center network is first provided, such as figure 2 As shown in, it mainly includes the following steps:

[0035] Connect the network nodes through the network card and the data path, and turn off the network card IP address setting, the network will fully run the CCN protocol; in this embodiment, the network card is a commonly used Ethernet network card, and the above data path may be a network cable;

[0036] Set the working mode of the network card to the promiscuous mode, so that broadcast and content data packets can be received to ensure the physical link of the content center network;

[0037] Set the maximum transmission unit leng...

Abstract

The invention relates to the technical field of computer architectures, in particular to a content-centric network bottom implementation method, a content-centric network and a communication method realized based on the content-centric network. The content-centric network bottom implementation method comprises the steps that network nodes are connected through a network card and a data path, and the IP address setting of the network card is closed; the operating mode of the network card is set to be a promiscuous mode; the length value of the maximum transmission unit of the network card is set so that an intact content data package can be accommodated; a bottom interface face, based on an original socket, of the network nodes is established; a physical interface of the network nodes and the bottom interface face are bound, and the network card and a specific transmitting interface are bound; content data are named and stored on a content originating node, and the content originating mode broadcasts the prefixes of the names of the content data through an external network card.

Description

technical field [0001] The present invention relates to the technical field of computer architecture, in particular to a method for realizing the bottom layer of a content-centric network, a content-centric network, and a communication method implemented according to the content-centric network. Background technique [0002] With the continuous development and changes of applications on the Internet, the existing Internet based on TCP / IP has gradually exposed many problems, such as poor security, no mobile support, unreliability, lack of flexibility, limited effectiveness, and rigidity to new applications. In response to these problems, many research institutions at home and abroad are currently conducting research on the design of the future network architecture. [0003] Content Centric Networking (CCN) is one of the important achievements of the current future Internet architecture research. Its core idea is to change the current end-to-end communication mechanism between...
