Problems solved by technology

In addition, this technology puts too much emphasis on the separation of the two namespaces and the role of the mapping system, making it completely dependent on the name resolution system, thus losing a lot of flexibility of NDN's original content-based routing

Abstract

The invention discloses a routing forwarding, routing table building and content obtaining method and a device thereof. The routing forwarding method comprises the following steps: a content request packet, which carries a content name of a request content and container information of the request content, is received; whether a forwarding entry which matches the content name of the request content exists in FIB is determined; whether a forwarding entry which matches a container sign in the container information exists in the FIB is determined when a forwarding entry which matches the content name of the request content doesn't exist in the FIB; and the content request packet is sent according to an interface in the matched forwarding entry when the forwarding entry which matches the container sign in the container information of the request content exists in the FIB. According to the embodiment of the invention, by increasing the container information based on the content name, dependence of routing forwarding on the content name can be minimized. Thus, it is possible to reduced routing table entries in a routing table, and it makes possible to solve problems such as route extension and the like which are caused by the content name.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method and device for routing and forwarding, establishing a routing table, and acquiring content. Background technique [0002] Although the Internet Protocol (Internet Protocol, referred to as "IP") has achieved great success and promoted the ubiquity of the Internet, at the beginning of the birth of IP, the "terminal" was placed at the core position, and the terminal identified by the destination IP address and source IP address Each IP packet carries a session between two terminals, so IP is a terminal-centric network protocol. Today, when people use the Internet, the main function is not to communicate between terminals, but to obtain information, such as online news, search engines, online music, online videos, blogs, microblogs, social networking sites, and online forums. The main purpose is the production, dissemination and sharing of variou...
