Problems solved by technology

[0005] The existing frame format analysis method based on the MAC layer multicast data frame in the HINOC system needs to be analyzed separately by different methods, which cannot be aimed at different types of HM terminal equipment, for example, HINOC3.0 HM terminal equipment, HINOC2 .0 The HM terminal equipment performs synchronous and parallel compatible analysis, therefore, the analysis efficiency of the frame format of the MAC layer multicast data frame is low

Embodiment Construction

[0042] The following description and drawings illustrate specific embodiments of the invention sufficiently to enable those skilled in the art to practice them.

[0043] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] Based on the existing parsing method, the resolution efficiency of the frame format of the MAC layer multicast data frame is low. For this reason, the application provides a frame format parsing method of the MAC layer multicast data frame based on the HINOC system and Device, to solve the problems existing in the above-mentioned related technical problems. In the technical solution provided by the application, the type information and the MAC layer multicast data frame of e...

Abstract

The invention discloses a frame format analysis method and device for an MAC layer multicast data frame based on an HINOC system. The method comprises the following steps: configuring a corresponding analysis mode for analyzing the frame format of the MAC layer multicast data frame according to the type of each piece of HM terminal equipment; according to the type of the current HM terminal equipment, analyzing the frame format of the MAC layer multicast data frame by adopting an analysis mode matched with the type of the current HM terminal equipment to obtain a corresponding analysis result. Therefore, according to the method provided by the embodiment of the invention, a corresponding analysis mode used for analyzing a frame format of an MAC layer multicast data frame is configured in advance according to the type of each HM terminal device, and the analysis mode comprises a first analysis mode matched with an HINOC3.0 HM terminal device and a second analysis mode matched with an HINOC2.0 HM terminal device. According to the invention, synchronization and parallel compatible analysis of the frame formats of the MAC layer multicast data frames can be carried out for different types of HM terminal devices, and finally the analysis efficiency of the frame formats is effectively improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for analyzing the frame format of a MAC layer multicast data frame based on the HINOC system. Background technique [0002] Multicast, also known as multi-target broadcast or multicast, is a transmission method used in the network. It allows the delivery of sent messages to a selected subset of all possible destinations, ie, delivery of information to well-specified multiple addresses. Is a method of communication between a sender and multiple receivers. An important application of multicast is the transmission of video programs, that is, the video program server will use multicast technology to transmit video program datagrams to user groups who have ordered the same program. Compared with unicast transmission, in the process of multicast transmission, the same Only one copy of the data packet of the program needs to be transmitted, which saves the tr...
