目前, 为了提高用户质量体验, 减少网络带宽压力, 运营商通过部署移 动服务增值网络来提供增值服务。 相关技术的移动增值服务网络的业务链 ( SC, Service Chain )主要有如下两种模式, 图 1 ( a )为相关技术的移动增 值服务网络的业务链模式一; 图 1 ( b )为相关技术的移动增值服务网络的业 务链模式二。
如图 1 ( a )所示, 在模式一中, 业务使能器( Service Node )通过交换机 静态链接在一起, 分组网关使用接入点名称(APN, Access Point Name )来 区分不同的业务链。 分组网关接收到报文后, 根据报文中的 APN将报文发送 给对应的业务链。 模式一中, APN对应的业务链相对静态, 业务使能器只能 按照既定的顺序进行部署, 在业务链中加入或移除一个业务使能器, 或者简 单改变业务链的逻辑都会导致网络拓朴的更改, 需要人工进行重新配置, 难 以适用于弹性的快速服务部署变动。
如图 1 ( b )所示, 在模式二中, 将所有业务使能器连接到一个路由控制 器, 分组网关将报文发送给路由控制器, 由路由控制器决定下一跳业务使能 器, 业务使能器接收到报文后进行相关处理, 将处理后的报文发送给路由控 制器, 路由控制器再决定下一跳业务使能器, 直到接入因特网或移动服务增 值网络。 模式二中, 路由控制器的资本支出 (CAPX, CAPital expenditure ) 高, 且与分组网关的功能重复。 发明内容
