Method of network management and of selection of network manager

一种网络管理方法，它是用第一桥114、115将至少连接了一个节点的总线111、112、113连接起来构成子网络110，用第二桥161～164将多个子网络110、120、130、140、150之间连接起来，对这样构成的网络系统100进行管理的网络管理方法，在该方法中，从各子网络中确定的子网络管理者中选定的网络管理者至少进行给各网络附加地址的管理，同时进行各网络之间的通信路径设定管理，网络管理者的选定等的网络管理能经常在一定的状态下适当地进行。 In a network managing method for managing a network system 100 composed by connecting buses 111, 112, 113 connected with at least one node by first bridges 114, 115 to compose a sub-network 110, and connecting plural sub-networks 110, 120, 130, 140, 150 by second bridges 161 to 164, by a network manager selected from sub-network managers determined in respective sub-networks, at least the management of assigning each sub-network with an address is done, and also the management of setting the communication path among the respective sub-networks is executed, so that the management of network such as selection of network manager or the like can be done appropriately always in a specific state.
