Problems solved by technology

The disadvantage of this method is: the header and data load of the COAP protocol data packet are shorter, and the header of the HTTP protocol data packet is longer
As a result, when a COAP packet is unpacked and encapsulated into an HTTP packet, a longer packet header is used to transmit a shorter data load, which greatly reduces transmission efficiency and wastes link resources

Embodiment

[0048] Figure 5 A schematic diagram of a data packet processing method based on a COAP protocol and an HTTP protocol is provided for an embodiment of the present invention. As shown, the main idea of ​​this method includes: data load merge determination algorithm design and dynamic priority control strategy design;

[0049] Wherein, the data load merge determination algorithm is used to combine the COAP data load in the data load queue in the data load queue, and write into the conversion mapping table according to the combined threshold and the transmission threshold in advance.

[0050] The dynamic priority control strategy is configured to set a wait time threshold for a data load in advance, and a timer is set to each of the data load queues, the timer being inserted from the data load into the data load. The queue starts timing until the data load is combined, and the timer time is long as the delay time of the corresponding data load.

[0051] The delay time of each of the ...

Abstract

The invention provides a data packet processing method based on conversion between a CoAP protocol and an HTTP protocol. The method comprises the following steps: unpacking a CoAP data packet to be sent, and removing a data packet header to obtain a data load; judging whether the size of the data load is smaller than a set merging threshold value or not, and if yes, putting the data load into a data load queue; and merging the data loads in the data load queue based on a dynamic priority control strategy according to a set sending threshold, adding an HTTP packet header to obtain an HTTP data packet, and transmitting the HTTP data packet through a link. According to the data load merging method for conversion between the CoAP protocol and the HTTP protocol, data load merging is achieved, and the problem that when conversion between the CoAP protocol and the HTTP protocol is carried out, a long packet header is used for transmitting a short data load can be solved; and moreover, the method is simple and easy to use, and facilitates the improvement of link transmission efficiency.

Description

Technical field [0001] The present invention relates to the field of data packet processing, and more particularly to a data packet processing method based on a COAP protocol and HTTP protocol. Background technique [0002] HTTP protocol: (Hyper Text Transfer Protocol, Hyper Text Transport Protocol), is the Internet application layer protocol, based on TCP / IP (Transmission Control Protocol / Internet Protocol, Transmission Control Protocol / Internet Protocol) communication protocol, belongs to application layer Object-oriented protocol, general packets have hundreds to a few thousand bits. [0003] COAP protocol: (Constrained Application Protocol, restricted application protocol), is one of the IoT application layer protocols, and the COAP protocol runs above UDP (User DataGram Protocol, User Data). For small devices in the Internet of Things, it is very difficult to implement TCP protocols and HTTP protocols. Therefore, the COAP protocol is a very small application layer prot...
