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： 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： 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： A spanning tree is formed for each of MST (Multiple Spanning Tree Protocol) instances defined by a VLAN ID and a COS value. Each terminal apparatus specifies the COS value corresponding to the TCP/UDP port number of a Ethernet frame to be transmitted, based on a conversion table indicating the correspondence of a TCP/UDP port number to a COS value and sets the specified COS value to the header of the Ethernet frame. Each of bridges in the transit network specifies the MST instance identifier of a received frame based on a conversion table indicating the correspondence of the MST instance identifier to the combination of a VLAN ID and a COS value and forwards the received frame in accordance with the spanning tree having the specified MST instance.
