Description

业务链的处理方法、装置与系统
本申请要求了2014年6月10日提交的、申请号为201410255254.8、发明名称为“业务链的处理方法、装置与系统”的中国申请和2014年12月27日提交的、申请号为201410834211.5、发明名称为“业务链的处理方法、装置与系统”的中国申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通讯技术领域,尤其涉及一种业务链的处理方法、装置与系统。
背景技术
当前,通信运营商在通信链路上部署了一系列的业务使能器,用以提供管道增值业务,业务使能器的不同组合被称作业务链。业务链可提供不同种类的功能,例如:可提供视频优化(Video optimization)、网络(Web)缓存、超文本传输协议(Hypertext transfer protocol,简称:HTTP)头增强、防火墙等业务功能。
通信运营商可通过以下关键部件实现对业务链的部署:业务配置管理系统、策略与计费规则功能(Policy and Charging Rules Function,简称:PCRF)实体、网关(Gate Way,简称:GW)、基于业务的路由(Service Based Routing,简称:SBR)实体、业务控制器(Service Controller)、负载均衡节点以及业务交换机(Service Switch),其中,SBR实体还可使用流量分类器(Traffic Classifier,简称:TC)代替,负载均衡节点与至少一个业务使能器连接。
现有技术中,通过业务链实现业务功能的具体过程如下:业务控制器从 业务配置管理系统处获取到业务链的描述信息。业务控制器还从业务交换机处获取到网络拓扑信息;根据网络拓扑信息,业务控制器确定网络中部署的负载均衡节点的种类,并生成业务链的路由规则表;业务控制器向业务交换机和SBR实体发送业务链的路由规则表。PCRF实体从业务配置管理系统处获取到业务链的描述信息。其中,所述业务链的描述信息具体如表1所示。
表1 业务链的描述信息
业务链的标识 业务链
业务链1 Video Cache<--->NAT
业务链2 Video Optimization<--->FW<--->NAT
…… ……
表1中,每个业务链的标识对应一条已配置的业务链,每条业务链由多个业务类型构成,每个业务类型也表示了构成业务链的业务使能器的类型。
业务控制器向业务交换机和SBR实体发送业务链的路由规则表后,PCRF实体通知SBR实体其所订阅的应用;当SBR实体检测到用户终端访问订阅的应用时,向PCRF实体发送上报订阅应用请求消息;PCRF实体根据上报订阅应用请求消息,从业务链的描述信息中选择出与应用对应的且为已配置完成的业务链并获取该业务链的标识;PCRF实体向SBR实体发送业务链的标识,以使得SBR实体接收到用户终端发送的数据包时,根据业务链的标识和业务链的路由规则表将数据包转发至业务交换机。业务交换机根据业务链的路由规则表,将SBR实体转发的数据包转发至负载均衡节点。负载均衡节点根据负载均衡算法,对可处理同一业务的业务使能器进行选择,并将交换机转发的数据包转发至选择出的业务使能器,由选择出的业务使能器对数据包进行业务处理。选择出的业务使能器对数据包进行业务处理后,再将数据包转发至业务交换机,业务交换机再次根据业务链的路由规则表,将数据包转发至另一个负载均衡节点处,直至数据包依照构成业务链的业务类型,完成全部的 业务处理。
但是,现有技术提供的技术方案也暴露出以下缺陷:1)每个负载均衡节点均需保存归属的业务使能器之间进行通信的会话状态信息,使得现有技术中网络实现复杂;2)业务链不易于扩展。例如,假设有网络地址转换(Network Address Translation,简称:NAT)、防火墙(Fire Wall,简称:FW)、视频缓存(Video Cache)、Video optimization 4种业务类型,则业务配置管理系统选择任意1个、2个、3个、4个业务类型可组成一条业务链,如果业务配置管理系统在先已配置完成多条业务链,但随着通信运营商增值业务种类的提升,使得业务链不易于扩展。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
为便于对本发明实施例的理解,下面将结合附图以具体实施例做进一步的解释说明,实施例并不构成对本发明实施例的限定。
实施例一
下面以图1为例详细说明本发明实施例提供的业务链的处理方法所应用的系统架构,图1为本发明实施例提供的业务链的处理系统架构图。所述系统可应用在移动互联网商业模式下。如图1所示,所述系统包括:应用检测实体110、PCRF实体120和业务控制器130。

所述业务控制器130,用于接收所述PCRF实体120发送的所述业务链路经请求消息,根据所述业务链的属性信息为所述业务链分配路径标识信息,并向所述PCRF实体120发送所述业务链的路径标识信息;
所述PCRF实体120还用于,接收所述业务控制器130发送的所述业务链的路径标识信息,并向所述应用检测实体110发送信用控制响应消息,所述信用控制响应消息包括所述路径标识信息,以使所述应用检测实体110根据所述路径标识信息,对接收到的所述用户终端发送的数据包进行转发处理。
具体地,用户终端根据用户的操作指令访问某一应用,被访问的应用根据用户终端发送的访问指令,进行自启动并为用户终端提供相应的服务。应用检测实体110执行步骤10,即获取应用的应用启动信息,将应用启动信息携带在信用控制请求消息(Credit Control Request,简称:CCR)中,向PCRF实体120发送信用控制请求消息。
PCRF实体120接收CCR消息后,根据携带的应用启动信息,PCRF实体120执行步骤20,即确定用于对应用进行业务处理的业务,向业务控制器130发送具有业务链的属性信息的业务链路径请求消息。
进一步地,在本发明实施例中,所述业务链的属性信息包括业务类型信息。所述PCRF实体120执行的根据所述应用启动信息确定用于对所述应用进 行业务处理的业务链的属性信息具体包括:根据应用启动信息包括的应用标识,确定用于对应用进行业务处理的至少一个业务类型信息。
在一个例子中,所述应用具体为在线视频应用,则应用启动信息包括的应用标识指示为在线视频。PCRF实体120根据在线视频,确定对在线视频进行业务处理的至少一个业务类型信息,确定的业务类型信息具体为:类型1:NAT业务;类型2:Video Cache业务和类型3:FW业务。PCRF实体120将确定的至少一个业务类型信息携带在业务链的属性信息中。
更进一步地,在本发明实施例中,所述业务链的属性信息还包括业务处理顺序信息。在实际应用中,PCRF实体120在确定对应用进行业务处理的业务类型信息的同时,还可确定出于业务类型信息对应的业务处理顺序。所述PCRF实体120执行的根据所述应用启动信息确定用于对所述应用进行业务处理的业务链的属性信息具体包括:根据应用启动信息包括的应用标识,确定用于对应用进行业务处理的至少一个业务类型信息;根据至少一个业务类型信息,确定用于对应用进行业务处理的业务处理顺序信息。
在另一个例子中,PCRF实体120根据在线视频,确定用于对在线视频进行业务处理的至少一个业务类型信息;根据至少一个业务类型信息,PCRF实体120确定用于对在线视频进行业务处理的业务处理顺序信息。例如,PCRF实体120在确定出类型1、类型2和类型3之后,确定业务类型信息对应的业务处理顺序,确定的业务处理顺序为:类型3、类型2、类型1;或者,业务处理顺序为:类型2、类型3、类型1等等。
更进一步地,在本发明实施例中,所述业务链的属性信息包括业务链标识信息。所述PCRF实体120执行的根据所述应用启动信息确定用于对所述应用进行业务处理的业务链的属性信息具体包括:根据应用启动信息包括的应用标识,确定用于对应用进行业务处理的业务链标识信息。
在一个例子中,所述应用具体为在线视频应用,确定用于对在线视频进行业务链标识为1的业务链处理,业务链标识1代表的业务链描述信息分别 预配置在所述PCRF实体和所述业务控制器实体上。例如:业务链标识1代表的业务链为:类型3->类型2->类型1。
需要说明的是,在本发明实施例中,PCRF实体还可结合网络以及用户签约等信息,进而确定业务链的属性信息。
业务控制器130在接收到业务链路径请求消息后,执行步骤30,即根据业务链的属性信息,为业务链分配路径标识信息,并向PCRF实体120发送业务链的路径标识信息。在本发明实施例中,业务控制器130根据业务链的属性信息,随机为业务链分配路径标识信息。
PCRF实体120在接收到业务链的路径标识信息后,执行步骤40,即向应用检测实体110发送信用控制响应消息(Credit Control Answer,简称:CCA),所述信用控制响应消息包括路径标识信息,以使应用检测实体110根据路径标识信息,对接收到的用户终端发送的数据包进行转发处理。
可以理解的是,应用检测实体110在接收到PCRF实体120发送的路径标识信息后,建立路径标识信息与应用的对应关系。以使得在接收到用户终端发送的数据包时,根据数据包所归属的应用对应的应用标识,确定对应的路径标识信息。
可选地,在本发明实施例中,所述系统还包括:至少一个业务使能器140;
所述业务控制器130还用于,根据所述业务链的属性信息,选择出构成所述业务链的所述业务使能器,根据已存储的网络拓扑信息和选择出的所述业务使能器,确定与所述业务链对应的业务链路径。
具体地,业务控制器130在为业务链分配完成路径标识信息后,根据业务链的属性信息选择出构成业务链的至少一个业务使能器140,根据已存储的网络拓扑信息和选择出的业务使能器140,业务控制器130确定与业务链对应的业务链路径。
可以理解的是,在通信系统中,存在着多个业务使能器实现同一个业务功能的情况,例如,业务使能器1、业务使能器2、业务使能器3均可实现NAT 业务,业务控制器可根据各业务使能器的当前处理数据包的占用情况、处理效率,从业务使能器1、业务使能器2、业务使能器3中选择出1个业务使能器作为构成业务链中实现NAT业务的业务使能器,同理,业务控制选择出实现Video Cache业务和FW业务的业务使能器。
需要说明的是,在一种实现方式中,业务控制器130可先根据业务链的属性信息为业务链分配路径标识信息,并向PCRF实体发送路径标识信息,业务控制器130再根据已存储的网络拓扑信息和业务链的属性信息,确定与业务链对应的业务链路径,当然在这种实现方式中,向PCRF发送路径标识信息和确定业务链路径无先后顺序之分;在另一种实现方式中,业务控制器130可先根据已存储的网络拓扑信息和所述业务链的属性信息,确定与业务链对应的业务链路径,再根据确定的业务链路径,业务控制器130为业务链分配路径标识信息,并向PCRF实体发送路径标识信息。
可选地,所述系统还包括业务交换机150,业务交换机150与多个业务使能器140连接。
所述业务控制器130还用于,根据所述业务链路径,确定业务链的路由规则表,并分别向所述应用检测实体110和所述业务交换机150发送所述业务链的路由规则表;
所述应用检测实体110还用于,接收所述业务控制器130发送的所述业务链的路由规则表,根据所述路径标识信息和所述业务链的路由规则表,将所述数据包转发至所述业务交换机150;
所述业务交换机150,用于接收所述业务控制器130发送的所述业务链的路由规则表,根据所述业务链的路由规则表,将所述应用检测实体110转发的所述数据包转发至对应的所述业务使能器150。
具体地,业务控制器130在确定出与业务链对应的业务链路径后,执行步骤50,即根据业务链路径,确定业务链的路由规则表,所述业务链的路由规则表中具体包括了每条业务链的路径标识信息和下一跳路由信息。业务控 制器130还向应用检测实体110和业务交换机150发送业务链的路由规则表。
业务检测实体110接收到业务链的路由规则表后,根据路径标识信息和所述业务链的路由规则表,将数据包转发至业务交换机150。
业务交换机150,接收到业务链的路由规则表后,根据业务链的路由规则表,将数据包转发至对应的业务使能器140。
在本发明实施例中,业务控制器130生成多个业务链的路由规则表,每个业务链的路由规则表包括的下一跳路由信息可不相同,所述下一跳路由信息为数据包转发的下一个设备或网元的IP地址或者MAC地址、或者设备或网元的端口号等。
例如,业务控制器130确定的业务链路径为FW业务使能器3->Video Cache业务使能器2->NAT业务使能器1,且业务链路径标识信息为10。
业务控制器130向应用检测实体110发送的业务链的路由规则表包括业务链的路径标识信息和与FW业务使能器3连接的业务交换机的IP地址或者MAC地址。业务控制器130向业务交换机150依次下发3个业务链的路由规则表,每个业务链的路由规则表均包括业务链的路径标识信息和1个业务使能器的端口号。例如,业务交换机150接收的业务链的第一路由规则表包括业务链的路径标识信息和FW业务使能器3的端口号;业务交换机150接收的业务链的第二路由规则表包括业务链的路径标识信息和Video Cache业务使能器2的端口号;业务交换机150接收的业务链的第三路由规则表包括业务链的路径标识信息和NAT业务使能器1的端口号。
进一步地,应用检测实体110接收到用户终端发送的数据包时,检测数据包所归属的应用,根据其对应的应用标识(例如,应用标识指示为在线视频),确定对应的路径标识信息(例如,路径标识信息为10)。应用检测实体110根据路径标识信息,确定业务链的路由规则表,并从路由规则表中获取业务交换机150的IP地址或者MAC地址。应用检测实体110将数据包转发至业务交换机150。
业务交换机150根据业务链的第一路由规则表,将应用检测实体110转发的数据包转发至FW业务使能器3,FW业务使能器3对数据包进行业务处理,并将业务处理后的数据包转发回业务交换机150。业务交换机150再次根据业务链的第二路由规则表,将数据包转发至Video Cache业务使能器2,Video Cache业务使能器2对数据包进行业务处理,并将业务处理后的数据包转发回业务交换机150。业务交换机150再次根据业务链的第三路由规则表,将数据包转发至NAT业务使能器1,NAT业务使能器1对数据包进行业务处理,并将业务处理后的数据包转发回业务交换机150。
业务交换机150确定数据包已完成全部的业务处理,则根据数据包携带的目的IP地址,将数据包转发至目的IP地址指示的设备或者网元处。
可选地,PCRF实体120向业务控制器130发送的业务链路径请求消息还包括应用检测实体的地址信息,所述应用检测实体的地址信息用于使业务控制器130向应用检测实体110发送业务链的路由规则表。通过该步骤,可使应用检测实体110根据路径标识信息和业务控制器130下发的业务链的路由规则表,对数据包进行转发处理。
可选地,在本发明实施例中,还可将应用检测实体110的地址信息在先存储在业务控制器130的存储器中,此时,PCRF实体120不再向业务控制器130发送应用检测实体的地址信息,业务控制器130根据已存储的应用检测实体110的地址信息,向应用检测实体110发送业务链的路由规则表。
相应地,PCRF实体120具体用于,向应用检测实体110发送信用控制响应消息,所述信用控制响应消息包括路径标识信息,以使应用检测实体110根据路径标识信息和接收到的业务控制器130发送的业务链的路由规则表,对接收到的用户终端发送的数据包进行转发处理。
需要说明的是,在本发明实施例中,业务控制器130向应用检测实体110发送业务链的路由规则表与业务控制器130向PCRF实体120发送路径标识信息可不限制时序关系。
因此,通过应用本发明实施例提供的业务链的处理系统,解决了现有技术中网络部署复杂,以及业务链不易扩展的问题。实现了网络中不再部署负载均衡节点,同时,按需创建业务链,适应多变的移动互联网商业模式,提升创建业务链的灵活性和可扩展性。

可选地,在本发明实施例中,还可将应用检测实体的地址信息在先存储在业务控制器的存储器中,此时,PCRF实体不再向业务控制器发送应用检测实体的地址信息,业务控制器根据已存储的应用检测实体的地址信息,向应用检测实体发送业务链的路由规则表。
相应地,步骤240具体为:PCRF实体向应用检测实体发送信用控制响应消息,所述信用控制响应消息包括路径标识信息,以使应用检测实体根据路径标识信息和接收到的业务控制器发送的业务链的路由规则表,对接收到的用户终端发送的数据包进行转发处理。
需要说明的是,在本发明实施例中,业务控制器向应用检测实体发送业务链的路由规则表与业务控制器向PCRF实体发送路径标识信息可不限制时序关系。
