Broadcast Routing Route a packet from a source to all nodes in the network Possible solutions: – Flooding: Each node sends packet on all outgoing links Discard packets received a second time – Spanning Tree Routing: Send packet along a tree that includes all of the nodes in the network

一、控制测量(control survey) 1、目的与作用 (1)为测图或工程建设的测区建立统一的平面控制网(horizontal control network)和高 程控制网(vertical control network) (2)控制误差的积累 (3)作为进行各种细部测量的基准
