摘要： In a WDM type PON system, each ONU comprises an optical transmitter capable to transmit optical signals with variable wavelengths, an optical signal receiving filter variable its receiving wavelength, and a control unit. An OLT selects in response to a wavelength allocation request from each ONU, a transmitting wavelength and a receiving wavelength out of currently free wavelengths and allocates these wavelengths to the requester ONT. The control unit of the ONU switches the transmitting wavelength of the optical transmitter and the receiving wavelength of the optical signal receiving filter to the wavelengths specified in a response message from the OLT and starts data communication.

摘要： The access server receives an authentication packet including an authentication result, a port change setting information, a port change time, a filtering setting information and a filtering time from the authentication server. The access server stores the respective information in the authentication packet into a memory. The access server refers to the memory, and in the case where the port change setting information on an arbitrary user identifier is set to perform port change, when it becomes the port change time, the access server changes the output destination of a packet from a user terminal to, for example, a proxy server B from a proxy server A. Besides, in the case where the filtering setting information on an arbitrary user identifier is set to perform filtering, when it becomes the filtering start time, the access server performs filtering on the port to which the user terminal is connected.
摘要翻译：访问服务器从认证服务器接收包括认证结果，端口改变设置信息，端口改变时间，过滤设置信息和过滤时间的认证包。访问服务器将认证包中的相应信息存储到存储器中。访问服务器是指存储器，并且在端口改变关于任意用户标识符的设置信息被设置为执行端口改变的情况下，当其变为端口改变时间时，访问服务器将数据包的输出目的地从用户终端例如是来自代理服务器A的代理服务器B.此外，在将任意用户标识符的过滤设定信息设定为进行过滤的情况下，当成为过滤开始时刻时，访问服务器执行在用户终端连接的端口上进行过滤。

摘要： A method for processing data received from at least one of VLANs, the method including: obtaining, based on a VLAN tag included in a MAC header of a MAC frame received from the VLAN and a first destination IP address included in an IP header of the MAC frame, a second destination IP address, changing the first destination IP address of the IP header to the second destination IP address, and generating an IP packet by deleting the MAC header from the MAC frame.
摘要翻译：一种用于处理从至少一个VLAN接收的数据的方法，所述方法包括：基于包括在从所述VLAN接收的MAC帧的MAC报头中包含的VLAN标签以及包括在所述VLAN的IP报头中的第一目的地IP地址获得 MAC帧，第二目的地IP地址，将IP报头的第一目的地IP地址改变为第二目的地IP地址，以及通过从MAC帧中删除MAC报头来生成IP分组。

摘要： Receiving terminals joining a multicast group are divided into sub groups and rekeying is performed only on the sub group which one of the receiving terminals has left. An encryption key management system having an encryption method is provided in which a multicast server is connected via an IP network, a seed node carries out encryption multicast communications among receiving terminals by using an encryption key, the receiving terminals are properly divided into the sub groups, the single encryption key is used for data distribution of the multicast server, and the number of decoding keys is equal to the number of divided sub groups.
摘要翻译：加入组播组的接收终端被划分为子组，并且仅在接收终端中的一个已经离开的子组上执行重新密钥。提供一种具有加密方法的加密密钥管理系统，其中多播服务器经由IP网络连接，种子节点通过使用加密密钥在接收终端之间执行加密多播通信，接收终端被适当地分成子组，单个加密密钥用于组播服务器的数据分发，解码密钥数量等于分割子组的数量。
