Description

中转节点贡献值获取方法及装置 技术领域
本发明涉及互联网技术领域, 尤其涉及中转节点贡献值获取方法及装置。
背景技术 在复杂网络条件下, 由于网络盾量问题, 经常出现通话节点之间不能保 持流畅通信。 上述情况下, 可以在系统中采用转发机制, 选择网络中的其他 节点作为通话双方的中转节点, 实现中转流量的目的, 进而提高通信质量。 对于 P2P系统中直接连接无法实现或连接效果不能满足业务需求(如延时过大 等情况)的情况下, 也需要采取中转机制实现相应业务。 具体方法如下:
( 1 )设置全局 Tracker服务器, 记录所有活跃超级节点 (Super Node )和 终端节点的状态信息, 一方面用于计费等业务的支持, 一方面用于中转节点 的调度。 在直接连接无法实现或连接效果不能满足基本业务需求的情况下, Tracker服务器根据全局 Super Node的负栽信息及终端节点的 Landmark分布
( GUID值), 调度合适的 Super Node或终端节点给请求中转服务的节点。
( 2 )采取 Super Node中转: 对于对话双方(如 UE Bob和 UE Alice进行通 话), 从所有或一部分 Super Node中选择最合适的一个(如 SN C ), 担任这次 会话的中转方, 链路连接方式为 UE Bob-SN C-UE Alice, 反向亦可, UE Bob 和 UE Alice之间的会话数据由 SN C负责转发。 对于 SN C的选择要满足: 中转 后路径 UE Bob-SN C-UE Alice的全路径质量满足业务需求,且在负载均衡的前 提下选择满足较优的结果。
( 3 )采取中转终端节点中转: 某一部分普通终端节点能够较好的连接两 个域的节点, 并具有在线稳定、 能力较强等特点, 这部分普通终端节点则成 为中转终端节点。 中转终端节点需要定期向 Tracker服务器汇报自己的负载情 况和心跳信息, 在需要中转功能的时候, 根据 Tracker服务器的调度, 在普通 终端节点发起会话时, 判断是否采用其担任中转方。
由于音质清晰、 费用低廉、 功能齐全及使用方便, 目前, Skype类软件成 为比较流行的通信工具。 用 Skype进行文件传输的时候, 如果双方不能直接连 接, 则会通过其它用户的资源来进行中转。 普通的同类软件在无法直连的时 候一般是通过服务器中转, Skype不利用服务器的资源, 而是通过网络中的其 他终端节点来进行中转。
在上述方法中, 普通中转节点对于中转网络流量做出了贡献, 有必要对 其进行奖励, 其前提是获取普通中转节点对中转流量的贡献。 但是, 普通中 转节点通常位于不可信的网络环境中, 系统侧单独从普通中转节点获取的贡 献信息不一定可靠, 存在未对中转流量做出贡献的普通节点欺诈系统侧的可 能。

以下结合附图对本发明的实施例进行说明, 应当理解, 此处所描述的实 施例仅用于说明和解释本发明, 并不用于限定本发明。
实施例一
本实施例和下述各实施例中, 其前提条件为: 可信节点处于可信网络环 境下, 而中转节点处于不可信网络环境下。 图 1 为本发明实施例一中转节点 贡献值获取方法的流程图。 如图 1所示, 本实施例包括:
步骤 S102: 获取参与会话的可信节点的计费信息;
步骤 S104: 获取参与会话的中转节点的计费信息;
步骤 S106: 判断中转节点的计费信息与可信节点的计费信息是否一致, 如是, 执行步骤 S108, 否则, 执行步骤 S110;
步骤 S108: 根据中转节点的计费信息, 计算中转节点的贡献值, 流程结 束;
步驟 S110: 中转节点的计费信息不可信, 不可以作为计算中转节点的贡 献值的依据, 流程结束。
本实施例中, 计费信息包括会话时长和 /或网络流量, 网络流量可由会话 所使用的编解码原理来推算以及实际测量来获得, 会话时长可以通过会话起 始时间、 会话终止时间来表示。 此外, 计费信息还可以包括: 会话发起方、 会话接收方、 会话起始时间、 会话终止时间、 会话流水号等信息。 本实施例中, 系统 居中转节点的计费信息中记载的会话时长和 /或网络 流量,计算中转节点的贡献值,如规定中转时长为 10小时,获取 1个贡献值; 或中转网络流量为 100M时,获取 1个贡献值;或者采取特定的规则计算贡献 值。
本实施例中, 步骤"判断中转节点的计费信息与可信节点的计费信息是否 一致"中, "一致"指预设的指标相同、 相关指标的计算结果相同或指标误差在 预设范围内。
本实施例中, 在判断中转节点的计费信息与可信节点的计费信息是否一 致时, 对系统预先设定的几个对应指标进行核对, 例如: 系统预先设定对会 话发起方、 会话接收方、 会话肘长三个指标进行核对, 则当可信节点和中转 节点的计费信息中, 上述三个指标都一致时, 认为中转节点的计费信息可信, 根据上述计费信息进行中转节点贡献值的计算。
本实施例中, 由于可信节点的计费信息与中转节点的计费信息一致, 因 此采用中转节点的计费信息计算贡献值, 与采用可信节点的计费信息计算贡 献值, 在本质上是相同的, 均应包含在本发明的保护范围之内。
本实施例中, 可信节点可以为参与会话的超级节点, 具体为负责会话发 起方会话处理的 Super Node和负责会话接收方会话处理的 Super Node, 也可 以为两者之一。
本实施例中, 计贽中心可以根据可信节点和 /或中转节点发送的计费请求 消息( Accounting Request, 筒称 ACR消息)来获取计费信息。 此外, 也可以 采用 FTP方式获取计费信息。
本实施例中, 当可信节点和中转节点提交计费信息的方式不一致或其他 原因, 导致计费信息的格式不一致时, 计费中心还可以将两者转换为统一格 式, 而后再进行计费信息是否一致的判断, 例如, 中转节点计费信息中记载 为中转时长, 而 Super Node计费信息中记栽为会话起始时间、会话终止时间, 则系统会根据预先的设置, 计算 Super Node的通话时长, 与中转节点上报的 中转时长进行比较, 进而判断中转节点上报的计费信息是否可信。 本实施例提出的方法在获取中转节点贡献值时, 通过对参与会话的可信 节点与中转节点的计费信息进行核对, 当两者一致时, 认为中转节点的计费 信息可信, 根据中转节点的计费信息计算中转节点的贡献值。 本实施例提出 的方法可有效保证在中转节点网络环境不可信的情况下, 真实可靠的获取中 转节点的贡献值, 防止计费中心被虛假的中转节点贡献所欺诈。

步骤 S226: 如果 Relay Node计费信息中, 如会话的发起方 /接收方、 中转 起始时间 /终止时间,和中转时长、网络流量等指标与 Super Node A、 Super Node B计费信息中的对应指标-会话的发起方 /接收方、会话起始时间 /终止时间,和 会话时长、 网络流量等指标一致, 则说明这次会话中所选择的中转节点所提 供的计费信息是可信的, 可以作为计费的依据; 反之, 则不能作为计费依据, 并可以采取其他措施, 如上报欺诈、 或进行追踪等。
本实施例中, 全局 Tracker服务器调度中转节点和现有技术相同, 为清楚 起见, 在图 2中没有进行体现。 Super Node和 /或中转节点提交相关计费信息 时, 可以采取实时计费的方式, 也可以采取非实时计费方式。 在非实时计费 方式中, 会话结束后, Super Node和 /或中转节点再向 CDF发送 ACR消息, 提交全部的计费信息。 上述两种方式在信令流程上稍有差别, 均与现有技术 相同, 此处不再进行详细描述。
本实施例在实施例一的基础上, 对实现步骤进一步细化。 本实施例提出 的方法具有实施例一的全部有益效果, 并且可实施性更强。
