Description

一种会话监控方法 艮务节点设备 技术领域
本发明涉及会话监控技术， 尤其涉及一种双栈用户的会话监控方法及 服务节点设备。 背景技术
参照图 1 , 现有的宽带接入网络的基本组网包括： 用户主机通过接入节 点 ( Access Node, AN )设备接入到服务节点 （ Service Node , SN )设备， 在 SN设备获取 IP地址和运营商分配的用户策略。 在用户上线的同时， SN 设备会建立相关的用户会话表， 并且通过不同的方式对用户进行保活， 以 便及时删除异常下线却占用设备系统资源的用户。
随着 IPv4地址的资源耗尽， IPv6接入的应用将越来越普遍， 但是目前 网络仍然是以 IPv4网络为主， 因此 IPv4网络转型到 IPv6网络存在着过渡 期， 在这个过渡期内， 一台主机同时拥有 IPv4/IPv6地址的双栈用户成为宽 带接入不可避免的接入类型。
基于 IPv4的以太网上的 IP协议（ IP over Ethernet, IPoE )接入使用动 态主机设置协议 ( Dynamic Host Configuration Protocol, DHCP )接入； 基 于 IPv6的 IPoE接入分为 DHCPv6接入、 无状态地址自动配置 （Stateless Address Autoconfiguration , SLAAC ) 接入等以太网上的点对点协议 ( Point-to-Point Protocol over Ethernet, PPPoE ) 的接入方式。 IPoE的双栈 接入会话分为 DHCP和 DHCPv6同时接入、 DHCP和 SLAAC同时接入这 两种类别。
现有技术中， SN设备对 IPoE双栈接入后的 IPv4会话和 IPv6会话是单 独进行会话监控的， 即当一台主机同时获取 IPv4和地址 IPv6时， SN分别 对这个 IPoE双栈用户的 IPv6地址和 IPv4地址进行会话监控， 这种实现方 式有如下缺陷：
SN设备需要对同一个用户的 IPv4会话和 IPv6会话分别进行监控， 这 不符合双栈用户的定义， 正比如 PPPoE的双栈一样， 双栈用户应该算一个 用户会话；
IP会话监控主要是为了防止主机异常离线后资源未被释放， 如果这个 主机异常离线的话， 那么这个主机的 IPv4会话和 IPv6会话都会中断， 因此 对同一用户主机同时进行 IPv4会话和 IPv6会话监控是一种重复劳动，无形 之中增加了 SN设备的处理压力， 具体来说，对双栈用户接入按照现有方式 的处理压力会是单栈用户的两倍。 发明内容
本发明所要解决的技术问题是提供一种会话监控方法及服务节点设 备， 以降低服务节点设备的处理压力。
为解决上述技术问题， 本发明提供技术方案如下：
一种会话监控方法， 包括：
当 IPoE双栈用户接入服务节点设备时， 所述服务节点设备为该 IPoE 双栈用户建立 IPv4会话和 IPv6会话；
所述服务节点设备从所述 IPv4会话和 IPv6会话中选择一种会话，得到 第一会话；
所述服务节点设备对所述第一会话进行会话监控， 得到会话监控结果； 所述服务节点设备根据所述会话监控结果处理所述 IPv4会话和 IPv6 会话。
其中， 所述服务节点设备根据所述会话监控结果处理所述 IPv4会话和 IPv6会话包括：
当所述会话监控结果指示所述第一会话处于非活跃状态时， 删除所述 IPv4会话和 IPv6会话；
当所述会话监控结果指示所述第一会话处于活跃状态时， 保持所述 IPv4会话和 IPv6会话。
其中，所述服务节点设备从所述 IPv4会话和 IPv6会话中选择一种会话， 得到第一会话， 包括：
所述服务节点设备从所述 IPv4会话和 IPv6会话中选择先成功建立的会 话作为所述第一会话。
上述的会话监控方法， 其中， 还包括：
所述服务节点设备接收到对会话的释放请求时， 如果请求释放的会话 为所述第一会话， 则在删除该会话后， 选择所述 IPv4会话和 IPv6会话中的 另外一种会话作为所述第一会话。
一种服务节点设备， 包括：
会话建立单元， 用于为 IPoE双栈用户建立 IPv4会话和 IPv6会话； 会话选择单元， 用于从所述 IPv4会话和 IPv6会话中选择一种会话，得 到第一会话；
会话监控单元， 用于对所述第一会话进行会话监控， 得到会话监控结 果；
会话处理单元， 用于根据所述会话监控结果处理所述 IPv4会话和 IPv6 会话。
其中， 所述会话处理单元进一步用于：
当所述会话监控结果指示所述第一会话处于非活跃状态时， 删除所述 IPv4会话和 IPv6会话；
当所述会话监控结果指示所述第一会话处于活跃状态时， 保持所述 IPv4会话和 IPv6会话。
其中， 所述会话选择单元进一步用于： 从所述 IPv4会话和 IPv6会话中选择先成功建立的会话作为所述第一会 话。
上述的服务节点设备还包括：
释放处理单元， 用于接收到对会话的释放请求时， 如果请求释放的会 话为所述第一会话， 则在删除该会话后，选择所述 IPv4会话和 IPv6会话中 的另外一种会话作为所述第一会话。
与现有技术相比， 本发明的有益效果是：
对于 IPoE双栈用户， 服务节点设备只对用户的 IPv4会话和 IPv6会话 中的一种会话进行监控， 并根据会话监控结果一并对该用户的 IPv4会话和 IPv6会话进行处理， 这样就能够降低服务节点设备的处理压力； 而且， 这 种处理方式更加符合双栈用户的定义。 附图说明

如果主机异常离线的话，那么这个主机的 IPv4会话和 IPv6会话都会中 断， 因此对同一用户主机可以只对 IPv4会话或者 IPv6会话进行会话监控。 基于此， 本发明实施例提供一种双栈用户的会话监控方法及服务节点设备， 对于 IPoE双栈用户， 服务节点设备只对用户的 IPv4会话和 IPv6会话中的 一种会话进行监控，并根据会话监控结果对该用户的 IPv4会话和 IPv6会话 进行处理， 这样就能够降低服务节点设备的处理压力。

对于 IPv4会话， 会话监控的方法可以是通过地址解析协议（Address Resolution Protocol, ARP )监控； 对于 IPv6会话， 会话监控的方法可以是 针对 IPv6地址的邻居发现过程。
会话监控结果包括： 会话处于非活跃状态和会话处于活跃状态。 会话 处于非活跃状态一般代表用户异常离线。
204: 所述服务节点设备根据所述会话监控结果处理所述 IPv4会话和 IPv6会话。
当所述会话监控结果指示所述第一会话处于非活跃状态时， 删除所述 用户的 IPv4会话和 IPv6会话； 当所述会话监控结果指示所述第一会话处于 活跃状态时， 保持所述用户的 IPv4会话和 IPv6会话。
另外， 用户还有可能主动释放 IP地址， 此时， 用户主机向服务节点设 备发送对会话的释放请求， 服务节点设备收到释放请求后， 会删除这个会 话。 在本发明实施例中， 在删除一个会话后， 如果删除的会话是当前正在 监控的会话， 则启动对另一个会话的监控。
即， 所述服务节点设备接收到所述用户对会话的释放请求时， 如果请 求释放的会话为所述第一会话， 则在删除该会话后， 选择用户的 IPv4会话 和 IPv6会话中的另外一种会话作为所述第一会话。
按照本发明实施例提供的双栈用户的会话监控方法， 设计出本发明实 施例的服务节点设备。

会话监控单元 30, 用于对所述第一会话进行会话监控， 得到会话监控 结果， 对于 IPv4会话， 会话监控的方法可以是通过 ARP监控， 对于 IPv6 会话， 会话监控的方法可以是针对 IPv6地址的邻居发现过程；
会话处理单元 40, 用于根据所述会话监控结果处理所述 IPv4会话和 IPv6会话， 具体为： 当所述会话监控结果指示所述第一会话处于非活跃状 态时，删除所述 IPv4会话和 IPv6会话； 当所述会话监控结果指示所述第一 会话处于活跃状态时， 保持所述 IPv4会话和 IPv6会话。
另外， 用户还有可能主动释放 IP地址， 此时， 用户主机向服务节点设 备发送对会话的释放请求， 服务节点设备收到释放请求后， 会删除这个会 话。 在本发明实施例中， 在删除一个会话后， 如果删除的会话是当前正在 监控的会话， 则启动对另一个会话的监控。
即， 所述服务节点设备还可以包括： 释放处理单元（图未示）， 用于接 收到所述用户对会话的释放请求时， 如果请求释放的会话为所述第一会话， 则在删除该会话后，选择所述 IPv4会话和 IPv6会话中的另外一种会话作为 所述第一会话。
以下给出本发明的三个应用实例。
第一应用实例

605: 用户手动申请 IPv6地址， 服务节点设备为用户建立 IPv6会话， 服务节点设备仍然对用户的 IPv4会话进行会话监控，并将 IPv4会话的监控 结果关联到 IPv6会话。
综上所述， 在本发明实施例中， 对于 IPoE双栈用户， 服务节点设备只 对用户的 IPv4会话和 IPv6会话中的一种会话进行监控，并根据会话监控结 果一并对该用户的 IPv4会话和 IPv6会话进行处理，这样就能够降低服务节 点设备的处理压力； 而且， 这种处理方式更加符合双栈用户的定义。
最后应当说明的是， 以上实施例仅用以说明本发明的技术方案而非限 制， 本领域的普通技术人员应当理解， 可以对本发明的技术方案进行修改 或者等同替换， 而不脱离本发明技术方案的精神范围， 其均应涵盖在本发 明的权利要求范围当中。

Claims

权利要求书

2、 如权利要求 1所述的会话监控方法， 其特征在于， 所述服务节点设 备根据所述会话监控结果处理所述 IPv4会话和 IPv6会话包括：
当所述会话监控结果指示所述第一会话处于非活跃状态时， 删除所述 IPv4会话和 IPv6会话；
当所述会话监控结果指示所述第一会话处于活跃状态时， 保持所述 IPv4会话和 IPv6会话。
3、 如权利要求 1所述的会话监控方法， 其特征在于， 所述服务节点设 备从所述 IPv4会话和 IPv6会话中选择一种会话， 得到第一会话， 包括： 所述服务节点设备从所述 IPv4会话和 IPv6会话中选择先成功建立的会 话作为所述第一会话。
4、 如权利要求 1所述的会话监控方法， 其特征在于， 还包括： 所述服务节点设备接收到对会话的释放请求时， 如果请求释放的会话 为所述第一会话， 则在删除该会话后， 选择所述 IPv4会话和 IPv6会话中的 另外一种会话作为所述第一会话。
5、 一种服务节点设备， 其特征在于， 包括：
会话建立单元， 用于为 IPoE双栈用户建立 IPv4会话和 IPv6会话； 会话选择单元， 用于从所述 IPv4会话和 IPv6会话中选择一种会话，得 到第一会话；
会话监控单元， 用于对所述第一会话进行会话监控， 得到会话监控结 果；
会话处理单元， 用于根据所述会话监控结果处理所述 IPv4会话和 IPv6 会话。
6、 如权利要求 5所述的服务节点设备， 其特征在于， 所述会话处理单 元进一步用于：
当所述会话监控结果指示所述第一会话处于非活跃状态时， 删除所述 IPv4会话和 IPv6会话；
当所述会话监控结果指示所述第一会话处于活跃状态时， 保持所述 IPv4会话和 IPv6会话。
7、 如权利要求 5所述的服务节点设备， 其特征在于， 所述会话选择单 元进一步用于：
从所述 IPv4会话和 IPv6会话中选择先成功建立的会话作为所述第一会 话。
8、 如权利要求 5所述的服务节点设备， 其特征在于， 还包括： 释放处理单元， 用于接收到对会话的释放请求时， 如果请求释放的会 话为所述第一会话， 则在删除该会话后，选择所述 IPv4会话和 IPv6会话中 的另外一种会话作为所述第一会话。
