Cisco SCCP  Cisco SCCP:瘦小客户端控制协议

  (SCCP:Cisco Skinny Client Control Protocol)

  瘦小客户端控制协议(SCCP:Cisco Skinny Client Control Protocol)是用于思科呼叫管理器及其 VOIP 电话之间的思科专有协议。有些供应商也支持该协议。

  在 VOIP 解决方案中,要求 LAN 或者基于 IP 的 PBX 的终端机操作简单,易于上手且相对便宜。相对于 H.323 推荐的相当昂贵的系统,SCCP 定义了一个简单且易于使用的架构。通过 SCCP,H.323 代理可以与瘦客户机进行通信。在这样的情况下,电话充当了 IP 上的瘦客户机。代理服务主要用于 H.225 和 H.245 信令。

  在 SCCP 结构中,大量的 H.323 处理任务就落在了称为 Cisco 呼叫管理器的 H.323 代理上。终端(电话)运行瘦客户端,这样该客户机只需消耗少量处理开销。客户机通过面向连接(基于 TCP/IP )的方式与呼叫管理器通信,从而建立到另一个 H.323 兼容终端的呼叫。一旦呼叫管理器建立这个连接,那么两个 H.323 终端就可以通过无连接(基于 UDP/IP)通信方式实现音频传输。这样,通过限制从 H.323 到呼叫管理器建立呼叫的复杂性、以及为终端间的实际音频通信使用 Skinny 协议来降低整个过程的费用和负荷。

  协议结构

  瘦客户机(即一个以太网电话)使用 TCP/IP 传输和接收呼叫,并使用 RTP/UDP/IP 和其它客户机或 H.323 终端进行音频通信。瘦信息通过 TCP 端口 2000 传送。信息类型如下所示:
