Method of sending data package and incidentally sending reverse interest package in content center network

Abstract

The invention discloses a method of sending a data package and incidentally sending a reverse interest package in content center network. The method includes the following steps : step 1, sending the interest package to the network to by a user A show that the user A is interested in the content; step 2, an intermediate node dealing with a request when the intermediate node in the network receives the interest package; step 3, combining a response data package and the interest package which needs to be requested by the user A to form a mixed data package by a user B when the user B wants to send a data request to the user A; step 4, the intermediate node splitting the mixed data package into a data package and a reverse interest package when the intermediate node in the network receives the mixed data package and respectively dealing with the data package and the reverse interest package; step 5, splitting the mixed data package by the user A when the user A receives the mixed data package, receiving the data package and delivering the data package to primary requested program, and meanwhile responding to the interest package by the user A and producing a corresponding data package. The method of sending the data package and incidentally sending the reverse interest package in content center network reduces transmission times of the package and improves information quantity and efficiency in once transmission.

Description

technical field [0001] The invention belongs to the field of network technology, and relates to piggybacking a reverse interest packet on a data packet in a content-centric network, which can be used for the transmission of two-way communication data in the content-centric network. Background technique [0002] Compared with the existing Internet, the content-centric network is a revolutionary evolution. Today's Internet structure is host-centric. When users want to obtain a certain content, they need to clearly indicate which host the content is stored on, and then the user accesses the host to obtain the content. In the content-centric network, when a user wants to obtain a certain content, he only needs to send a request for the content to the network, without specifying the storage location of the content, the network can find the content and return it to the user . [0003] In the content-centric network architecture, routing based on names is implemented. When a use...
