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： The invention relates to an EPON bridge apparatus and a forwarding method thereof. In case of receiving frame from the network port or the PON port, the apparatus associates the port having the received frame inputted with source MAC address of the received frame to learn the information in an FDB table which manages port information for the learned MAC address. Then the apparatus refers to the FDB table to remove LLID from upstream frame, and then forwards the upstream frame to the network port, while attaching LLID corresponding to destination MAC address to downstream frame to transmit to the PON port. Bridging between ONUs are possible with flooding capability using anti-LLID. It provides VLAN-LLID translation mode with support for VLAN tag addition/removal at the ONU side. It also provides multicast pruning function for the downstream.

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： The invention provides a method and apparatus for allocating a dynamic band width of an EPON and an EPON master apparatus using the same. The bandwidth allocation is cycle based where every predetermined cycle, static gates are generated for all ONUs and dynamic gates are generated according to the reports using the remaining grant resource. The method for allocating an upstream bandwidth to transmit data from the ONUs to an OLT is as follows. A total allocatable grant length is calculated for the given cycle. A requested amount of grant length needed to transmit upstream data in each ONU is set based on report values collected from the report frames from all ONUs in the EPON. Then, distribution is made sequentially and repeatedly in a cycle by taking a basic unit from the total grant length and adding it to the grant length of the ONUs until the total allocatable grant length becomes 0 or the grant length allocated to all ONUs satisfy the requested amount of the grant length set in all ONUs.

摘要： Edge extracting method and apparatus using a neural network performing a function of diffusing an excitation. The method and apparatus continuously detect a variety of intensity changes of an image via a function having a variety of frequency characteristics. An edge of a fixed object is detected from images continuously input, and an edge of a moving object is selectively detected from the images. The edge extracting apparatus includes a first neural network which receives an image signal. The first neural network derives a Gaussian function representing the regularity of an excitatory response and an inhibitory response to a spot excitation of the image signal. The apparatus also includes a second neural network which detects edges of an image represented by the image signal by convolving the Gaussian function and the image signal.
