Description
网络资源的共享处理、 共享方法及装置、 系统 技术领域 本发明移动通信领域, 更具体地说, 涉及一种网络资源的共享处理、 共享方法及 装置、 系统。 背景技术 随着宽带网络的大规模普及、 互联网业务类型日新月异式的增长, 以及业务质量 的不断提升, 用户带宽需求的飞速增长, 电信运营商的宽带接入网络面临是越来越大 的负载压力, 运营商的带宽扩容速度已经渐渐跟不上宽带用户的需求增长速度, 同时 由于用户使用习惯、 作息时间等等的多样性越发明显, 传统的根据新增用户数扩容的 方式成本巨大、 已经不能满足网络发展的需求。 宽带网络的发展需要依靠更大范围的资源共享来实现资源的有效利用, 而非盲目 的物理带宽资源。传统的宽带网络中, 网络带宽的规划是根据用户数量, 实现小区级、 小局点的带宽资源共享, 包括线路带宽资源和业务节点带宽资源, 从目前的网络发展 速度来看, 线路带宽资源相对业务节点带宽资源而言相对比较充足, 而后者明显已经 遇到较大的资源困境, 一个很有代表性的问题就是, 大部分用户在晚高峰时段都无法 享受到运营商承诺的最大带宽, 原因是这段时间内大部分的用户都集中在城市的居住 区, 居住区的业务节点的带宽资源使用率极高, 而城市办公区的业务节点普遍处于较 低使用率、 甚至闲置状态。 反之, 工作时段城市居住区的宽带网络设备的资源利用率 远低于晚高峰时段。 如何解决宽带网络的资源利用效率问题, 进而实现最大限度的利用现有的网络资 源、 降低扩容频率、 减少网络成本投入, 这是当前全球电信运营商面临的主要问题之 一。 在宽带接入领域, 尤以提升业务节点 (即宽带接入服务器、 业务路由器等设备) 的资源利用率为主要需求。 当前业界的主流技术方案是业务节点的池组化方案, 通过 更大范围的业务节点资源共享, 实现全天候、 大规模地区的宽带资源合理利用, 在有 限的资源下实现不同地区的峰时谷时的资源互补、 不同类型的用户的资源共享。 就业务节点的资源池组化技术方案而言,首先要实现不同业务节点间的用户信息、 网络信息的资源共享, 当前主流的方案是业务节点间的分布式协商, 就所谓 Full Mesh (全互联) 方式实现业务节点间的信息全共享。 但这种方式随着资源共享的规模越来
