应用程序/主机/网关/网络级别的参考模型

Question

第 9 页，RFC793描述 TCP 在协议层次中的位置如下：

   +------+ +-----+ +-----+       +-----+
   |Telnet| | FTP | |Voice|  ...  |     |  Application Level
   +------+ +-----+ +-----+       +-----+
         |   |         |             |
        +-----+     +-----+       +-----+
        | TCP |     | RTP |  ...  |     |  Host Level
        +-----+     +-----+       +-----+
           |           |             |
        +-------------------------------+
        |    Internet Protocol & ICMP   |  Gateway Level
        +-------------------------------+
                       |
          +---------------------------+
          |   Local Network Protocol  |    Network Level
          +---------------------------+

这个参考模型有名字吗？
