Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0035] figure 1 It shows the implementation process of the method for compressing, sending and processing multiple Interest packets in the content-centric network provided by the embodiment of the present invention.

[0036] The method includes the following steps:

[0037] Step S101, add a compressed interest packet, and divide the content name part of each compressed interest packet into two parts: the common prefix of each interest content name and the suffix of each interest content name;

[0038] Step S102, when the user wants to obtain a certain content, he starts to request data, and continuou...

Abstract

The invention discloses a content-centric networking multi-interest packet compression sending and processing method. The method comprises that compression interest packets are added, a content name part of each of the compression interest packets is divided into common prefixes of various interest content names and suffixes of the various interest content names, multiple interest packets which have a common prefix are compressed to be compression interest packet request data, when a network node receives the compression interest packets, the common interest prefix and the interest suffix are sliced to be an integrated content name, searching is carried out in content caching, a undetermined interest table and forwarding information table, forwarding interfaces are determined, for each interface, the common prefixes of the content names in all the interests to be sent are extracted, and the common prefixes and the surplus suffixes of the content names are combined to form a compressed interest packet which is sent.. The method effectively reduces the number of the interest packets in the network, and consumption of bandwidth is reduced, the compression problem of the multiple interest packets which have the same name prefix in the content center network is solved, and the content-centric networking multi-interest packet compression sending and processing method has stronger popularization and application value.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a method for compressing, sending and processing multiple interest packets in a content-centric network. Background technique [0002] Compared with the existing Internet, the content-centric network is a revolutionary evolution. The existing Internet is host-centric. When a user wants to access a certain content, he needs to specify which host the content is stored on, and then the user goes to the host to access the content. In a content-centric network, when a user wants to access a certain content, he only needs to submit a request to the network to access the content, without specifying where to obtain the content, and the network is responsible for delivering the content to the user. [0003] In the Content-Centric Networking (CCN) architecture, a routing mechanism based on names is implemented. CCN nodes are responsible for the storage, forwarding and routin...
