    • An ATM network switch (100) includes a plurality of slot controllers (112a-h) each coupled to a switch fabric (114) and an external link (116a-h). In addition, each slot controller (112a-h) is coupled to a system controller (122) via a LAN (120). A processor of each slot controller (112a-h) is programmed to forward Q.2931 messages to the system controller (122) via the LAN (120) and to receive information from the system controller (122) via the LAN (120). The system controller (122) is programmed to interpret the Q.2931 messages, update the routing tables of the slot controllers (112a-h) via the LAN (120), and forward a packet containing the Q.2931 messages to an appropriate slot controller (112a-h) via the LAN (120) whereafter the slot controller (112a-h) assembles ATM cells containing the Q.2931 messages for transmission.
    • ATM网络交换机(100)包括多个时隙控制器(112a-h),每个时隙控制器耦合到交换结构(114)和外部链路(116a-h)。 另外,每个时隙控制器(112a-h)经由LAN(120)耦合到系统控制器(122)。 每个时隙控制器(112a-h)的处理器被编程为经由LAN(120)将Q.2931消息转发到系统控制器(122),并且经由LAN(120)从系统控制器(122)接收信息。 系统控制器(122)被编程为解释Q.2931消息,经由LAN(120)更新时隙控制器(112a-h)的路由表,并将包含Q.2931消息的分组转发到适当的时隙 控制器(112a-h),之后时隙控制器(112a-h)组装包含用于发送的Q.2931消息的ATM信元。
