Problems solved by technology

[0003] This data packet transmission method transmits data packets according to the IP address of the node. When the IP address of a node in the network changes, all nodes in the entire network need to update the IP address in the address table, and the address update is relatively cumbersome.

Embodiment 1

[0048] Such as figure 1 As shown, this embodiment provides a data packet transmission method, including:

[0049] 110. The adapter receives the service request sent by the initiating node.

[0050] 120. The adapter determines a matching destination node according to the service request.

[0051] For example, the adapter determines the service required by the originating node according to the service request, and the node in the network that provides the service required by the originating node is the destination node.

[0052] 130. The adapter determines path information from the starting node to the destination node, where the path information is used to identify a path from the starting node to the destination node.

[0053] 140. The adapter sends the path information to the originating node, so that the originating node transmits a data packet to the destination node according to the path information.

[0054] Wherein, the adapter may be a server or the like, which is not ...

Embodiment 2

[0061] This embodiment provides a data packet transmission method, which can be applied to a network system including multiple groups, each group containing at least one node, and the network system can adopt image 3 Internet architecture shown.

[0062] Such as image 3 As shown, the Internet architecture includes: a smart service layer 101 , a resource adaptation layer 102 and a network node layer 103 .

[0063] Smart service layer 101, resource adaptation layer 102 and network node layer 103 all include entity domain and behavior domain;

[0064] The smart service layer 101 includes at least one network service, and each network service is represented by a service identifier in the entity domain in the smart service layer 101 and a service demand behavior description in the behavior domain in the smart service layer 101;

[0065] The resource adaptation layer 102 includes at least one network group, and each network group is represented by the group identification of the...

Embodiment 3

[0128] Such as Figure 9 The present embodiment shown provides a network system, the network system includes a plurality of groups, each group includes at least one node, the network system includes: an adapter 91, an initial node 92, wherein:

[0129] The adapter is used to receive the service request sent by the starting node; determine the matching destination node according to the service request; determine the path information from the starting node to the destination node; send the path information to the starting node, and the path information is used to identify the starting node to the destination node. the path of the destination node;

[0130] The starting node 92 is used to send a request to the adapter, so that the adapter determines the matching destination node according to the service request, and determines the path information from the starting node to the destination node; receives the path information sent by the adapter; transmits data to the destination n...

Abstract

The invention discloses a data packet transmission method and a network system. Path information is used for transmitting data packets, and the work load for address updating can be reduced. The method comprises that an initial node sends a service request to an adapter, the adapter determines a matched destination node according to the service request and determines the path information from the initial node to the destination node, and the path information is used for identifying a path from the initial node to the destination node; the initial node receives the path information sent by the adapter; and the initial node transmits the data packets to the destination node according to the path information. According to the data packet transmission method and the network system, the data packet transmission is achieved through the path information from the initial node to the destination node; in the prior art, the data packets are transmitted according to internet protocol (IP) addresses of nodes, and when the IP address of one node in a network is changed, the IP addresses in an address list are required to be updated for the nodes of the whole network; and compared with the prior art, the data packet transmission method and the network system have the advantages of being capable of effectively reducing the work load for address updating.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a data packet transmission method and a network system. Background technique [0002] In a communication network, a data packet can be forwarded by a node, and the data packet can be transmitted to a destination node. In the Internet based on IP addresses, each node has a unique IP address in the entire network as an identity identifier. When transmitting a data packet, the IP address of the destination node is carried in the header of the data packet. The IP address of the node queries the address table to determine the destination node, and finally transmits the data packet to the destination node. [0003] This data packet transmission method transmits data packets according to the IP address of the node. When the IP address of a certain node in the network changes, all nodes in the entire network need to update the IP addresses in the address table, and the address updat...
