背景技术 Background technique

[0002] 现有的局域网技术具有较强及灵活的数据接入服务功能,因此局域网得到广泛的应用,在现有的局域网技术上所采用的传输协议中,比较常见的为WIFI认证协议,WIFI技术在无线传输接入方面米用的传输协议为IEEE 802. 11,在有线局域网传输中常见的传输协议是IEEE 802. 3,其共同的特点都是采用载波侦听及冲突检测的方式来控制网络中信息的传送,对于现有的局域网网络传输方面,归结起来存在如下问题: 1、 局域网用户终端接入局域网的认证过程较长,不利于局域网用户终端的快速接入及在移动时的快速切换,造成接续中断时间较长; 2、 局域网用户终端的无线数据接入传输采用用户竞争模式,造成无线数据接入延时过大,相对于局域网用户终端的接入无绝对的优先权及较好的可靠性保障;对于采用免竞争工作模式,由于采用了轮询方式,当相同 [0002] The prior art local area network having a strong and flexible data access services, thus widely used local area network, a local area network transmission protocol in the conventional technology used in the more common a WIFI authentication protocol, WIFI in the radio transmission technology transmission protocol used for access in the meter IEEE 802. 11, the common wired LAN transmission transport protocol is IEEE 802. 3, which are the common characteristics and the way of carrier sense collision detection employed to control transmitting the network information for the existing LAN network transmission, there is a problem boils down to: 1, the LAN to access the LAN terminal user authentication process is longer, is not conducive to rapid access to the LAN and the user terminal at the fast moving switching the connection break resulting in a long time; 2, wireless LAN access transmission data using a user terminal user competition mode, the wireless data access delay caused by too large with respect to the user terminal to access the wireless LAN absolute priority and more guarantee good reliability; Free competition for the mode of operation employed, the use of polling, when the same 入点的局域网用户终端较多时,则轮询时间较长,局域网用户终端的数据传输效率下降;虽然在数据帧的传输过程中运用了不同的帧间隔来设定不同的优先级,但这只是一种减少冲突、提高部分帧的传输几率的方式,不具有绝对的优先级功能及固定传输速率的保障; 3、 局域网有线传输部分采用以太网传输协议,其用户数据传输也采用竞争模式,在网络设备中,如局域网交换机、路由器、网关,大多采用了存储转发工作模式,造成数据传输延时过大,并且也无绝对优先权及较好的可靠性保障; 4、 由于企业局域网中,接入的监测监控等数据终端较多,由于多用户的接入竞争,接入用户的数据实时性传输能力低; 上述四点,造成局域网传输的实时性效果较差,影响局域网用户终端的实时数据传输的使用效果,如语音信号的延迟造成的通话质量下降 When many point of LAN user terminals, then the polling longer time, data transmission efficiency decreases LAN user terminals; although the use of different frame intervals during the transmission of a data frame to set different priorities, but only a method of reducing conflicts, increase the probability of transmission of the frame mode does not have an absolute guarantee of a fixed priority function and transmission rate; 3, a wired LAN using Ethernet transmission protocol transmission section, which is also the use of competitive user data transmission mode, network devices such as LAN switches, routers, gateways, they use a store and forward mode, resulting in data transmission delay is too large, and no absolute priority and better reliability guarantee; 4, due to the corporate LAN, the ground monitoring and control of the data terminal and the like more, since the multi-user access competition, low access real-time user data transmission capacity; the above-described four points, LAN transmission caused by poor real-time effect, the influence of the real time data LAN user terminals use of the effect of the transmission, such as delayed speech signal quality degradation caused by the call 视频信号的延迟造成的图像变化,实时监控数据的延时对设备控制及生产流程的不利影响;在实际生产调度通信工作中,需要有通信连接速度快,实时性强,优先权级别具有绝对的强制性优先通信,并具有全呼、组呼、 通告、插入呼叫及紧急插入所要求的实时数据传输技术,以满足实时数据用户终端对语音数据、视频数据及实时控制数据传输的需要,而现有的局域网数据传输协议下的数据传输方法不能适应这些要求,而单纯的实时数据传输网络不具有局域网的数据接入服务功能。 Image change caused by the delayed video signal, delay adversely affect real-time monitoring and control data to the equipment of the production process; actual production scheduling in a communication operation, communication connections requires a fast speed, real-time, with the absolute priority level preferential communication mandatory, and has a full call, group call, advertisement, emergency calls and insert inserted real time data transmission technology required to meet the real-time data of the user terminal to the voice data, video data and control data requires real-time transmission, but now data transmission method in some LAN data transfer protocol can not meet these requirements, and simple real-time data transmission network does not have a local area network data access services.
