摘要： In a PON system, a PON-ID assigned to a connected ONU before replacement is assigned to a newly connected ONU after the replacement and, setting data before the replacement is succeeded also after the replacement. An OLT includes a PON-ID state where a management state of the PON-ID is stored, a PON-ID management table where the PON-ID and an ONU serial number of the connected ONU and setting data are correspondingly stored and, a delete ONU table where the PON-ID and an ONU serial number of a replacement object are correspondingly stored. When the OLT receives an ONU replacement instruction from an operation system, the PON-ID assigned to the ONU of the replacement object is assigned to an ONU newly connected during the ONU replacement.

摘要： Communication of a terminal accessing a network by using a static IP address is cut off. A packet transfer device includes plural ports, a protocol processing unit and a control unit. An IP address distribution request by a DHCP protocol from a client terminal is transferred to a DHCP server, and an application of the IP address distribution is received. At that time, the packet transfer device stores information (IP address, MAC address) of the client terminal into a storage unit. Besides, information (IP address, MAC address) of the client terminal is stored into the storage unit also from an ARP packet by ARP resolution by the client terminal or ARP resolution by the packet transfer device itself. When the IP addresses of the stored DHCP packet and the ARP packet coincide with each other, port filtering is performed to the client terminal having transmitted the ARP packet.
摘要翻译： 通过使用静态IP地址访问网络的终端的通信被切断。 分组传送装置包括多个端口，协议处理单元和控制单元。 来自客户端的DHCP协议的IP地址分配请求被传送到DHCP服务器，并且接收到IP地址分发的应用。 此时，分组传送装置将客户终端的信息（IP地址，MAC地址）存储到存储单元中。 此外，客户终端的信息（IP地址，MAC地址）也通过客户终端的ARP分辨率从ARP分组存储到存储单元中，或者由分组传送装置本身存储在ARP分辨率中。 当存储的DHCP报文和ARP报文的IP地址彼此一致时，对发送ARP报文的客户端进行端口过滤。

摘要： OLT is provided with a field for storing the number of effective bits for searching ONU serial numbers, a field for storing a search start serial number and a field for storing a search end serial number, and ONU serial numbers are searched from the search start serial number to the search end serial number within the number of effective bits to automatically perform acquisition of the ONU serial number and ONU connection. An ONU automatic connection method for an ATM-PON system is provided by which an ONU serial number is searched efficiently without registering the ONU serial number from OpS to OLT.
