摘要： The present invention provides a device and method for allocating a bandwidth to a plurality of optical network units (ONUs) for transmitting an uplink frame in the EPON. The bandwidth allocation device includes a plurality of optical network units and an optical line terminal (OLT). The optical network units classify uplink data to be transmitted to an optical line terminal according to a predetermined priority, and transmit the classified uplink data by receiving an allocated bandwidth according to each class from the optical line terminal. The optical line terminal preferentially distributes a predetermined bandwidth for transmitting uplink frames of a highest priority class to the optical network units and then dynamically distributes a remained bandwidth form transmitting the uplink frames for remained classes.

摘要： Provided is a method for setting a security channel between an OLT and at least one ONU in an EPON. In detail, a channel is generated by which the OLT makes a reciprocal security capability agreement with the ONU that wants to set a security channel in a discovery interval and then automatically registers the ONU with the security capability agreement. The security channel is set by which the OLT distributes an encryption key for the security with the ONU completed with the security capability agreement. A renewal point of the encryption key is shared by transmitting a message indicative of a time to change the encryption key between the OLT and the ONU both completed with the encryption key distribution.

摘要： A method for controlling a security channel for reducing system load by extending the use period of a security association key is provided. In this method, an upper bit initial value of an initialization vector of an encryption algorithm and a using range thereof are shared between a transmitting side and a receiving side when a security channel is created. Then, a secure association is created between a transmitting side and a receiving side by setting an association number, a next packet number which is a lower bit value of an initialization vector, and a secure association key. Afterward, a packet number is modified whenever a frame is transmitted until all of packet numbers are used. When all packet numbers are used, the upper bit value of the initialization vector changes.

摘要： An asynchronous transfer mode (ATM) protection triggering method using “received-AIS” flag determines whether the failure generation position is generated within a protected domain or not, by determining whether the “received-AIS” flag is “0” in case that a node detecting a failure link transmits an end-to-end AIS cell to a downstream side node, and a source point passing the end-to-end AIS cell sets the “received-AIS” flag to “1” and then receives “AIS cell receiving” signal from a sink point of the protected domain, thereby obviating a CRC-10 calculation problem and a backward compatibility.
