Embodiment Construction
[0041] The present invention will be described in detail below in conjunction with specific embodiments.
[0042] Reference figure 1 The present invention is a method for piggybacking reverse interest packets in data packets in a content center network. The present invention needs to modify the message type and add a new message type—hybrid data packet. The mixed data package contains the complete data package and interest package.
[0043] For example, set the message type to 2 bits and the offset to 16 bits. If the message type is 00, the packet is a pure interest packet, if it is 10, the packet is a pure data packet, and if it is 11, The packet is a mixed data packet, which includes a data packet and a reverse interest packet. When the message type is 00 or 10, the message does not have a 16-bit offset; when the message type is 11, there is a 16-digit offset after the message type, which represents the mixed data packet The point of separation between data packets and interes...

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 data packets piggybacking reverse interest packets in a content center network, which can be used for the transmission of two-way communication data in the content center network. Background technique [0002] Compared with the existing Internet, the content center network is a revolutionary evolution. Today's Internet structure is host-centric. When a user wants to obtain a certain content, it is necessary to clearly indicate which host the content is stored on, and then the user accesses the host to obtain the content. In the content center 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 center network architecture, routing based on names is implemented. When a user wants t...
