The routing protocols of local internets are discussed. Taking AppIeTalk internets which are interconnected by bridge as an example, the routing algorithms for datagram deliver protocol (DDP) and routing table maintenance protocol (RTMP) are addressed.

• 本文研讨了局部网际网的路由协议,文中以采用桥互连的Apple Talk局部网际网为实例,讨论了数据报传输协议(DDP)的路由算法,以及路由表维护协议(RTMP)。
