Problems solved by technology

[0004] However, each data fragmentation will correspond to a data reorganization, and each data fragmentation and data reorganization will consume a certain amount of CPU and other hardware resources. If data fragmentation and data reorganization are performed multiple times, it will consume a lot of hardware resources

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0024] In order to reduce the number of fragments and thereby reduce the consumption of hardware resources, the embodiment of the present application provides a method and device for determining the length of a message, which are applied to the detection end. The method for determining the length of the message includes:

[0025] After determining that the detecting end and the detected end are in the same layer 2 network, sending a first detection message of a first length to the de...

Abstract

The embodiment of the invention provides a message length determination method and device. The method comprises the steps of: after it is determined that a detection terminal and a detected terminal are located in the same two-layer network, sending a first detection message with a first length to the detected terminal, if a first response message is received, confirming whether a second responsemessage is received or not, if not, determining the first length to the message length of message segmentation, if the first response message is not received, confirming whether a third response message is received or not, if yes, determining the third length of the third detection message as the message length of the message segmentation. According to the technical scheme provided by the embodiment of the invention, the maximum message length for message segmentation is determined from the preset length range to reduce the number of times of segmentation, even directly transmit the messages with large message lengths with no need for segmentation, reduce the consumption of hardware sources, save the segmentation time and improve the data transmission efficiency.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for determining the length of a message. Background technique [0002] The AP (Access Point, access point) establishes a connection with the AC (Access Controller, access controller) through the CAPWAP (Control And Provisioning of Wireless Access Points Protocol Specification, wireless access point control and configuration protocol). According to the CAPWAP protocol, the AC establishes a CAPWAP channel with the AP. [0003] The length of the message in the required transmission message between the AC and the AP may be greater than the MTU (Maximum Transmission Unit, maximum transmission unit), where the MTU is the maximum length of the user-defined payload in the transmittable message. When the length of the data carried in the message is greater than the MTU, the message needs to be fragmented by CAPWAP. After fragmentation, the lengt...
