Problems solved by technology

However, since the caching strategies of each router have the same influencing factors, they are the time and / or frequency at which data is requested; if the same data is requested at the same frequency or time in each router, the data is cached locally in each router The life cycle in is also the same, which may cause the same data in each router to be deleted at the same time, thus affecting the data diversity of the NDN system and affecting the data hit rate of the NDN system

Embodiment approach

[0083] In the first feasible implementation manner, the priority of data can be divided into two levels, that is, the priority attribute of data can include: first priority and second priority; the level of the second priority A level higher than the first priority; that is, in this embodiment, each data corresponds to a priority attribute, and the priority of the data indicated by the priority attribute can be low priority (that is, the first priority) or High priority (i.e. second priority).

[0084] In the second feasible implementation manner, the priority of data can be divided into three levels, that is, the priority attributes of data can include: first priority, third priority, and second priority; The second priority level is higher than the third priority level, and the third priority level is higher than the first priority level; that is, in this embodiment, each data corresponds to a priority attribute, and the priority attribute indicates The priority of the data...

Abstract

The embodiment of the invention discloses a data processing method, a router and an NDN system. The data processing method can include the steps of obtaining priority attributes of data when the data are received, setting life cycle attributes for the data according to the corresponding relation of the priority attributes and the life cycle attributes, and storing the data with the life cycle attributes in a local cache. According to the data processing method, the router and the NDN system, the life cycle attributes of the data are set according to the priority attributes of the data, the differential cache strategy can be achieved, the data diversity of the NDN system is improved, and meanwhile the data hit rate of the NDN system is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field of data processing, in particular to a data processing method, router and NDN (Named Data Networking, named data network) system. Background technique [0002] NDN provides a data-based architecture, using data as an entity in the network, and using "name" as the unique identifier of data. NDN defines two formats of data, one is the data used to send the request, which can be called "Interest packet"; the other is the data containing the content, which can be called "data packet" ". Data in each format uses a name as a unique identifier. For example, the name of the Interest packet is used to uniquely identify the request to obtain the content of the Interest packet, and the name of the data packet is used to uniquely identify the content of the data packet load. [0003] The NDN system includes a data source and at least one router. Among the...
