Method and device for sending data and method and device for receiving data

Abstract

The embodiment of the invention provides a method and a device for sending data and a method and a device for receiving data. The method for sending data comprises the steps of receiving business data sent by an application layer, encapsulating the link layer of the business data, writing a destination media access control (MAC) address into the business data, encapsulating the physical layer of the business data of which the link layer is encapsulated, writing a destination MAC address to the business data according to the link layer encapsulation, and sending an Ethernet data packet generated after the physical layer encapsulation. The embodiment of the invention can reduce the workload of sending and receiving data, increase the speed and the efficiency of sending and receiving data, improve the network resource utilization ratio and lower the data transmission cost.

Description

technical field [0001] The invention relates to a wireless communication network, in particular to a data sending method and device, and a data receiving method and device. Background technique [0002] An existing wireless communication network usually includes a wireless communication terminal and a wireless network part. The wireless network is composed of a base station, a base station controller, and a core node. The base station controller can be integrated into the base station or the core node. [0003] In various wireless communication networks, Ethernet is a data communication network that transmits data between user equipments through Media Access Control (hereinafter referred to as MAC) switching and forwarding, and has been widely used as a telecommunications bearer network. application. In wireless network communication technology, data must be transmitted by means of various network protocols. In the prior art, when Ethernet is used as a bearer network betwe...

Problems solved by technology

[0006] Since the bearer network is Ethernet, and Ethernet devices exchange and forward MAC frames based on Layer 2 information such as MAC addresses, there is no need to analyze IP header information. Therefore, IP header information is useless information in Layer 2 In the process, it is also necessary to add the IP header to the head of the data through the IP layer in the IP protocol stack, which unnecessarily increases the workload of sending data, prolongs the data sending time, and seriously affects the data sending speed and transmission efficiency; and, because the length of the useless IP header occupies as much as 20 bytes, it needs to occupy a certain bandwidth of the Ethernet bearer network, wasting limited network resources, and unnecessarily increasing the number of nodes in the wireless communication network. cost of data transfer between
