Problems solved by technology

However, in the scenario where the data source moves, the content request packet should be forwarded to the node where the data source is moved, and NDN needs to update the route. Because the NDN routing table itself has routing expansion problems, that is, the entries in the core routing table can be Reaches two hundred times the number of Border Gateway Protocol (BGP) routing entries in the current network. If each mobile terminal needs to have its own routing entry in the routing table, the number of routing entries in the routing table It will be larger, and the existing hardware conditions are difficult to meet such a large-scale routing table processing
In addition, due to operations such as routing updates brought about by mobility, more routing fragments will be brought about, making

Abstract

The invention discloses a data source movement handling method applied to the Information Centric Center (ICN), a message forwarding method and its device. The data source movement handling method comprises the following steps: when a target container enters a second container through a first container, route of the target container is registered in the second container; when the target container enters the second container through the first container, the target container communicates with an analytic system such that the analytic system updates an access container of the target container to the second container through the first container; and when the target container moves inside the first container, route of the target container in the first container is updated through the communication between the target container and the first container. According to the data source movement handling method provided by the embodiment of the invention, data resource movement is supported while frequent and tedious routing update will not be introduced. In addition, content name of content cannot be changed so as to maintain durability of the content name. Thus, feasibility of the ICN framework is enhanced, and user experience is raised.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, relate to a processing method for data source movement applied to an information-centric network ICN, a method for forwarding a message, and a device thereof. 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 ...
