摘要
传统铁路通信传输SDH网络管理中心LT,对于划分ID只按不同车站划分,对于同一车站不同信息平台的2M接口不做划分,只按照接入网2M接口的接入,自动分配时隙;至于该数据在信息平台处理的周期、数据归口为哪一种车站业务数据、数据的具体内容,不做处理。数据包较大的信息量会造成信道拥堵,造成重要的通信数据丢失或者形成误码。无法保证反馈的相对平衡。在LT终端采用新的反馈平衡程序,保证同等重要、数据量大小基本一致的信息包,在同一个ID下输入信息终端处理后,进行平衡反馈,有效地提高通信信道使用率,解决信道拥堵问题。
LT,of the traditional railway communication transmission SDH network management center for the division of ID divided by different stations,not to divide 2M interface for different information platforms in the same station,the only access by the access network 2M interface,automatic allocation of time slots;As for the processing cycle of the data in the information platform,centralized data for which a station business data,data content,not treated Packets larger amount of information will cause channel congestion,resulting in important communications data loss or the formation of the error.Cannot guarantee that the feedback is relatively balanced.In the LT terminal using the new balance of feedback procedures to ensure that basically the same size are equally important,the amount of data packets,with an ID to enter the information terminal processing to balance feedback effectively improve the communication channel usage,solve congestion of the channel.
