Description

服务质量QOS参数配置方法、装置及系统 技术领域
本发明涉及通信领域，尤其涉及一种服务质量QOS参数配置方法、装置及系统。
背景技术
随着无线路由器，便携访问接入点(Access Point,简称AP)，电力猫等设备的普及，家庭网络组网变得越来越复杂。同时，家庭网络承载了上网，视频，语音，下载，游戏等多种业务，这些业务对带宽和延时等服务质量(Quantity of Service，简称QoS)有着不同的要求。如果家庭网络设备不能合理实施QoS，则可能出现家庭网络塞车，比如下载文件时视频业务出现卡住停顿，看视频时游戏掉线等。因此，家庭网络的QoS逐渐成为家庭网络的技术热点。
QoS处理流程通常包括分类(Classifying)，监管(Policing)，标识(Marking)，排队(Queueing)，调度(Scheduling)，整形(Shaping)等方面。其中分类功能发生在端口接收输入报文阶段，是QoS处理的第一步，其过程是根据信任策略或者根据分析每个报文的内容来确定将这些报文归类到以服务类别(Class of Service，简称CoS)值来表示的各个数据流中，从而保证特定报文数据流的QoS优先级。
分类的依据有很多种，常用的分类依据包括：传输控制协议(Transmission Control Protocol，简称TCP)和用户数据报协议(User Datagram Protocol，简称UDP)端口号，IP地址或媒体访问控制(Media Access Control，简称MAC)地址，以及物理端口号。
(1)TCP和UDP端口号
大多数应用会采用固定的知名TCP或UDP端口进行通信，如HTTP采用TCP端口80，流媒体实时流传输协议(Real Time Stream Protocol，简称RTSP)采用TCP端口554，可以在网络设备上根据知名端口号配置这些数据流的CoS参数来保证相关业务的QoS。这个方法的缺点是如果遇到端口号不固定的应用程序，则无法配置端口号从而保证优先级。另外，一个应用可能用到多个端口号，配置的工作量比较大。
(2)IP地址或MAC地址
每个网络终端设备都会有自己的IP/MAC地址，对特定IP/MAC地址配置QoS优先级可以保证这台设备的所有数据流的优先级。这个方法的缺点是管理员必须在网络设备上手工配置固定的IP/MAC地址，并将终端设备的IP/MAC地址固定下来。 如果终端设备采用DHCP方式获取IP，重新开机后IP可能会动态变化。如果设备损坏换新设备，MAC地址也会不同，上述两种情况，事先配置的参数则无法发挥作用。
(3)物理端口号
与源IP地址类似，网络设备的物理端口号可以对应具体的终端设备，这是最简单的分类形式，目前中国电信定制的家庭网关通常将第二个以太网端口固定设置为机顶盒端口，并保证这个端口的数据优先级。这个方法的缺点是用户必须将特定设备连接在特定的物理端口上，连接错误则无法保证优先级。
针对相关技术中QOS参数配置存在的无法保证QOS优先级的问题，尚未提出有效的解决方案。
发明内容
本发明提供了一种服务质量QOS参数配置方法、装置及系统，以至少解决现有技术中QOS参数配置存在的无法保证QOS优先级的问题。
根据本发明的一个方面，提供了一种服务质量QOS参数配置方法，包括接收终端设备发送的数据包，所述数据包中携带有所述终端设备的设备类型和设备地址；根据所述设备类型和预先设置的设备类型和服务类别对应关系确定所述终端设备的服务类别；根据所述设备地址和所述服务类别配置所述终端设备的QOS参数。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。。
在本实施例中提供了一种服务质量QOS参数配置方法，图1是根据本发明实施例的服务质量QOS参数配置方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，接收终端设备发送的数据，该数据包中携带有终端设备的设备类型和设备地址；
步骤S104，根据设备类型和预先设置的设备类型和服务类别对应关系确定终端设备的服务类别；
步骤S106，根据所述设备地址和所述服务类别配置所述终端设备的QOS参数。
通过上述步骤，根据所接收到的终端设备发送的设备类型和预先设置的设备类型和服务类别对应关系确定终端设备的相应服务类别，并根据设备地址和所确定的服务类别配置终端设备的QOS参数，解决了相关技术中QOS参数配置存在的无法 保证QOS优先级的问题，进而达到了保证QOS优先级的效果。
在另外一个实施例中，该数据包还可以包括DHCP Discovery数据包。终端设备向网络设备发送的数据包可以有很多种，但发送的如果是DHCP Discovery数据包，网络设备上必然需要设置有DHCP服务器，而DHCP服务器能够为终端设备提供IP地址及为网络设备配置参数，因此，优选地，终端设备发送DHCP Discovery数据包。
在另外一个实施例中，数据包中携带的设备地址可以是终端设备的MAC地址。设备地址可以有很多种，比如可以是IP地址，但是终端设备的MAC地址是全球唯一的，而IP地址等是可以发生变化的，因此，MAC地址更有利于识别终端设备。
数据包中携带终端设备的设备类型和设备地址的方式可以有很多种，优选地，可以是在数据包的源MAC地址中携带终端设备的MAC地址，在数据包中的Option60字段中携带有用于标识终端设备的设备类型。通过上述方式，可以更加快速地解析出数据包中有关终端设备的各种信息。

QOS参数可以包括很多种，但是优选地，包括QOS优先级参数。通过配置终端设备的QOS优先级参数，才能保证终端设备的QOS优先级。
上述QOS参数配置方法可以应用在很多场景，但优选地，应用在家庭网络设备上。家庭网络中由于没有网络管理人员并且可能终端设备的种类繁多，因此，上述方法应用在家庭网络的配置场景中，效果更为明显。
在本实施例中还提供了一种QOS参数配置装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

图6是根据本发明实施的DHCP协议流程图，如图6所示，终端设备启动时，通过DHCP协议获取IP地址，DHCP的第一步是发送DHCP Discovery数据包，数据包的源MAC地址是终端设备自身MAC地址，数据包中的Option 60字段(格式如表2)用于标识设备厂商类型和配置；
