Description

网络配置的发送方法及装置、存储介质、电子装置 技术领域
本公开实施例涉及通信领域,具体而言,涉及一种网络配置的发送方法及装置、存储介质、电子装置。
背景技术
有线宽带接入是家庭宽带,企业专线,公共WiFi等的基础接入业务,是除移动宽带之外的第二大主流宽带接入业务,随着交互式网络电视IPTV,高清视频等新兴接入业务的高速发展,有线接入网关设备(宽带远程接入系统(Broadband Remote Access System,BRAS))转控面一体的传统模式越来越不适应云化网络架构、新业务的快速开发与交付等需求。基于SDN/NFV(Software-Defined Network/Network Function Virtualization)的BRAS转发和控制面分离,已经成为业界的共识,并在一些国内国际市场获得商用部署,国际国内的相关标准组织也正在积极标准化,以实现接入设备转发面和控制面的互联互通。
BRAS转控分离机制下,控制面负责集中处理用户接入及用户服务策略,并将用户ACL及QoS策略下发到转发面部署执行。通常情况下,控制面通过管理接口向转发面下发用户服务策略,如通过管理接口的网络配置(Network Configuration,简称为NETCONF)协议下发用户策略数据模型语言(Yet Another Next Generation,简称为YANG)模型。但是,转控分离BRAS的转发面执行层次化业务质量(Quality of Service,简称为QoS)HQoS,对于YANG模型的层次和架构设计,不同厂商的设备架构以及层次化设计都必然不一样,因此很难统一标准化,即设计一个标准化的基于YANG模型的QoS策略实现异厂家互通,将非常复杂甚至不可能。
针对上述技术问题,相关技术中尚未提出有效的解决方案。

下面结合具体实施例对本公开进行说明:
转控分离BRAS转发面层次化QoS体系,颗粒度由粗到细依次涉及设备接口、子接口、用户组、用户、用户业务(业务流)等QoS策略,YANG模型配置方案中,控制面需要依次嵌套配置,并通过管理接口NETCONF协议下发到转发面,通常配置在一张YANG模型表中,转发面根据该层次化QoS YANG模型对设备接口及用户进行QoS策略配置。
本实施例提出一种基于类型长度值(Type Length Value,简称为TLV)的扁平化转控分离BRAS QoS策略下发和配置流程,即针对BRAS转发面的多层次QoS策略,为每个层次定义一个或多个规则-动作对,由规则-动作对的组合映射对应的QoS策略,转发面可根据设备的具体结构情况,选择该设备支持的规则-动作对进行解析并部署配置,不支持的规则-动作对或组合,则直接忽略不做处理。因此,不同转发面设备无需支持统一的YANG模型配置数据结构,从而灵活高效的解决了层次化QoS YANG模型的异厂商互通问题。
特别的,基于TLV的QoS规则-动作对,不必通过管理接口的NETCONF协议下发,而是可以通过状态控制接口协议下发,灵活性更好,下发效率更高。
具体的,BRAS转发面ACL&QoS规则-动作对是基于基础规则和基础动作的二级TLV结构,如图4所示,一个规则-动作对类型定义一套唯一的规则和动作组合,构成特定的ACL&QoS基础配置单元,一个QoS策略由一个或多个规则-动作对构成。转控分离BRAS控制面根据策略、规则-动作对两级结构,向转发面下发ACL&QoS配置策略,转发面根据自身设备结构特征选择配置或不配置该策略。在两级TLV结构下,BRAS转发面层次化QoS实现了扁平化下发,不受层次化整体数据结构的约束,如图5所示。
在规则-动作对TLV消息结构中,转控分离BRAS转发面ACL&QoS策略可通过如下两种方式体现:
ACL&QoS策略TLV,为每一种层次化ACL&QoS策略定义一种TLV,其包含的规则-动作对组合由ACL&QoS策略TLV语义定义,规则-动作对TLV作为ACL&QoS策略TLV的下级嵌套TLV;
ACL&QoS策略由转控分离BRAS控制面向转发面下发的消息类型表示,其包含的规则-动 作对TLV组合作为该消息的数据负荷。
如图5所示,QoS策略的基础配置通过规则-动作对TLV由控制面生成并通过控制接口下发到转发面,每个规则-动作对由转发面单独解析,并根据自身设备结构特征以及运营商公共配置需求,决策部署或者忽略相应的规则-动作对TLV。由于规则-动作对TLV执行无层次化结构编排和下发,转发面设备不再受传统层次化ACL&QoS YANG模型结构的约束。
转控分离BRAS转发面层次化ACL&QoS策略,包含系列基础匹配规则和基础处理动作,按照ACL策略、接口QoS策略、用户(含用户组)QoS策略,分别列举典型的基础规则和基础动作。本公开旨在通过规则-动作对TLV的扁平化QoS策略模式代替传统YANG模型,其他未来新增、扩展的规则和动作,均可通过上述二级TLV结构进行QoS策略构建、下发和部署配置。

综上所述,通过用户ACL&QoS策略及其规则-动作对多级TLV描述传统网络配置管理数据,并通过非管理接口协议下发用户ACL&QoS策略;通过规则-动作对TLV模式扁平化传统的层次化QoS配置数据;配置设备可根据自身结构灵活选择配置数据,不再受传统YANG模型数据结构的约束;通过控制接口协议如S-CUSP,PFCP等下发配置数据,更加高效灵活;解决了转控分离BRAS YANG模型异厂商无法有效互通的行业瓶颈。
