本实施例针对当前RTN系统中仅针对媒体进行加速，对信令和非媒体数据缺乏加速措施的问题以及当前RTN系统中对于媒体的加速没有做精细化分级加速导致网络资源利用率底的问题提出了一种通用数据分级加速的RTN系统。该RTN系统不仅针对媒体数据进行加速，同时也针对信令和其他非媒体数据进行加速，提升媒体传输业务整体用户体验；另外，该RTN系统针对加速的数据进行精细化分级，为高优先级数据规划优质的传输路径，为低优先级数据规划一般的传输路径，针对媒体传输场景不同规划与之相匹配的链路，在提升用户体验的同时实现RTN传输资源利用价值最大化。可以应用于实时音视频通信相关行业，如AR/VR、云游戏、互动直播、云电脑、远程教育、视频会议、视频监控以及各种OTT应用等。

图4是根据本公开实施例的边缘节点组成的框图，如图4所示，本实施例通用数据分级加速的RTN系统中边缘节点的主要由客户端接入模块、数据分级模块、数据转发模块、链路探测模块组成。客户端接入模块负责接受客户端的接入请求，并负责与客户端之间的数据传输。数据分级模块负责对数据类型进行分级，数据优先级从1到4分为四个优先级，数字越小优先级越高。主要是根据需要传输的数据类型向路由调度中心查询该类型数据传输的优先 级，同时获取路由调度中心规划的数据传输的路径信息以及目的节点的接收端口信息。数据分级模块收到该类型数据传输的优先级信息和传输路径信息以及目的节点的接收端口信息后与原始数据包组成新的传输数据包，完成数据封装操作。数据收发模块负责将封装完成后的数据包根据传输路径的要求转发到中转节点，其中优先级高的数据优先转发。链路探测模块负责接收路由调度模块的探测请求指令，指令中会包含需要边缘节点探测的具体转发节点，接收指令后随机进行链路探测，探测指标包含丢包、延迟、抖动、带宽等，探测完成后将探测的具体参数定时发送到路由调度模块。
图5是根据本公开实施例的通用数据分级加速的RTN系统中中转节点的组成框图，如图5所示，数据接收模块负责高性能接收来自边缘节点或者其他中转节点的数据，并将数据交给数据处理模块处理。数据处理模块负责将封装后的数据解封装，然后去掉路径中本节点的信息病更新路径长度字段，暴露路径中下一节点的信息以便数据在路径中的快速转发，然后对数据进行封装。数据转发模块负责将封装完成后的数据包根据传输路径的要求转发到中转节点，其中优先级高的数据优先转发。链路探测模块负责接收路由调度模块的探测请求指令，指令中会包含需要边缘节点探测的具体节点(包含转发节点和其他边缘节点)，接收指令后随机进行链路探测，探测指标包含丢包、延迟、抖动、带宽等，探测完成后将探测的具体参数定时发送到路由调度模块。
图6是根据本公开实施例的通用数据分级加速的RTN系统中路由调度中心的组成框图，如图6所示，拓扑管理模块负责整个RTN网络的拓扑关系的管理，包含边缘节点和中转节点的增加、删除操作，节点之间连接关系的变更操作。探测管理模块负责向边缘节点和中转节点下发探测请求，并负责接收边缘节点和中转节点的探测数据。路径规划模块负责根据边缘节点和中转节点的拓扑关系和探测数据实时进行路径的规划，每一组起始节点和目的节点最多规划4条路径，并分1到4四个级别，其中1表示路径延迟小、带宽大；2表示路径延迟小，带宽小；3表示路径延迟大、带宽大；4表示路径延迟大、带宽小。实时规划出的分级传输路径保存在内存中供边缘节点查询。数据分级管理模块负责接收边缘节点的分级查询请求和路径查询请求，并根据路规划模块的结果将分级数据和路径数据下发给边缘模块。其中分级策略为：云电脑、云游戏、AR/VR、视频会议、互动直播等低延迟大带宽等场景媒体数据使用级别1的路径；信令和非媒体数据使用级别2的路径；视频监控、OTT应用等对带宽要求高，对延迟要求第的场景使用级别3的路径；其他非重要数据传输使用级别4路径。
本实施例提出的一种通用数据分级加速的RTN系统流程如下：
步骤1，路由调度中心的拓扑管理模块将用户配置的RTN系统中节点和链接关系保存在内存中，包含边缘节点和中转节点的网络地址信息；
步骤2，路由调度中心的探测管理模块根据拓扑关系向边缘节点和中转节点下发探测请求；
步骤3，边缘节点和中转节点的链路探测模块在接收到路由调度中心的探测请求后随机开始链路网络参数的探测请求，并将探测结果定时上报到路由调度中心的路径规划模块；
步骤4，路由调度中心的路径规划模块根据边缘节点和中转节点的拓扑关系和实时探测数据进行路径规划，每一组起始节点和目的节点最多规划4条路径，并分1到4四个级别。实时规划出的分级传输路径保存在内存中供边缘节点查询。
步骤5，当业务请求开始，客户端连接到边缘节点的客户端接入模块后，边缘节点的数 据分级模块根据业务类型向路由调度中心的数据分级管理模块查询数据分级信息和数据传输路径，然后将原始数据结合收到数据分析信息和数据传输路径以及目的端口等信息封装成新的数据包。图7是根据本公开实施例的封装后的数据格式的示意图，如图7所示。其中目的端口为路径中最后一个节点(一般为边缘节点，图6中为节点6)的接收端口；中间转发节点统一使用可配置的固定端口，以便减少端口协商动作，加速传输。
步骤6，数据封装完成后通过边缘节点的数据收发模块发送到中转节点。
步骤7，中转节点的数据接收模块接收到封装后的传输数据后，数据处理模块会对数据进行解封装，然后去掉路径中本节点的信息并更新路径长度信息，暴露路径中下一节点的信息以便数据在路径中的快速转发，然后对数据进行封装。例如，本转发节点为节点1，收到的封装数据如图7所示，去掉本节点1信息后重新封装后的数据格式，图8是根据本公开实施例的转发节点重新封装后的数据格式的示意图，如图8所示，下一转发节点为节点3。同时中转节点会判封装数据中的路径长度是否为1来判断当前节点是否是传输路径中的倒数第二个节点，如果不是，则将数据转发到下一节点的固定数据接收端口，如步骤8所示；如果当前节点是传输路径中的倒数第二个节点，则将数据转发到封装数据中目的端口字段描述的端口，如步骤9所示。
步骤8，中转节点的数据转发模块根据封装后的数据直接获取下一转发节点的信息，并根据优先级信息进行数据转发。高优先级的数据优先转发。
步骤9，边缘节点的数据模块在接收到中转模块的数据后，对数据进行解封装，获取到原始数据，然后将原始数据发送到目的客户端。
至此，完成了通用数据在RTN系统中的分级加速传输的过程。
