Embodiment 1

[0090] This embodiment discusses the application of the connection-oriented named data network transmission control protocol in NDN communication, and its implementation process is as follows figure 1 shown. This embodiment is based on the NDN network. The consumer sends an Interest packet to request data, and the producer responds with a data packet to respond to the request. The consumer is A, the producer is B, the interface used by the consumer communication is a, and the interface used by the producer is b , the name of the data required by the user is datawanted, and its size is 300 bytes. An example of NDN communication using the transmission control protocol of the present invention is as follows:

[0091] Step I, consumer A and producer B respectively create their own sockets, specifically including the following sub-steps:

[0092]Step I.1 Producer B selects the port b to interact with the consumer, and creates a socket (B, b) representing the interaction endpoint,...

Abstract

The invention relates to a connection-oriented data transmission method, and belongs to the technical field of network data transmission. The method comprises the steps that a consumer A and a producer B create sockets; the consumer A sends a connection request interest packet, and the producer B continuously receives and connects a request data packet reply; the producer B sends a connection confirmation interest packet, and the consumer A continuously receives and connects a confirmation data packet reply; the consumer A sends an inquiry interest packet, and the producer B replies a notification data packet; the consumer A sends a data request interest packet, and the producer B replies a data content data packet; the consumer A sends a release interest packet, the producer B replies andsends the release interest packet, and the consumer A replies a release data packet; the producer B periodically sends a detection interest packet and replies from the consumer A; and the consumer Aperiodically sends the detection interest packet, the producer B replies the detection data packet, and the consumer A and the producer B periodically detect the retransmission timer and retransmit the retransmission timer. The method realizes reliable transmission of data.

Description

technical field [0001] The invention relates to a connection-oriented data transmission method, in particular to a connection-oriented named data network (Named DataNetworking, NDN) data transmission method, which belongs to the technical field of computer network data transmission. Background technique [0002] Named Data Network (NDN) is a network system with named data as the main communication object. In NDN, by naming the data content and communicating according to the content name information of the data packet, the current communication method based on the IP address of the network is changed, and the separation of the data content and the host address is realized, and its robustness and scalability It is better than TCP / IP network. The communication in NDN is driven by the content requester, that is, the content requester needs to send a data content request first, and the content publisher will reply the corresponding data content to the data content requester acco...
