摘要： An apparatus (101, 110) and method for channel acquisition in a communication system (100) provides for selecting a channel, from a multiplicity of available channels (205), and determining whether the selected channel is the properly assigned channel for data and other information to be received by the apparatus (101, 110). The selected channel is monitored for a predetermined or adaptive energy level (210), a predetermined modulation mode (215), for a protocol signal, and for a protocol signal having an identification specifying the particular apparatus (225), such as a protocol frame containing a serial number corresponding to the apparatus. When a protocol signal having an identification specifying the particular apparatus (225) is received, the selected channel is acquired (250) for reception of data and other information. Channels are selected on the basis of searching first for those channels most likely to be assigned to the particular apparatus, such as previously assigned channels (305, 320, 325), followed by a focused search initially in the vicinity of a central channel under a particular channel plan (345, 355). The process may also be repeated utilizing a variety of channel or frequency plans (375).

摘要： An apparatus (101, 110) and method provide for memory utilization and management which may expand the number of write operations for limited write memories, such as non-volatile memory, to provide for more optimal performance of systems such as computer or communication systems. Such memory utilization, in accordance with the present invention, includes allocating portions of the limited write memory, as a memory structure, for an ordinal or parameter designation. Upon system initialization or start up, comparison of adjacent ordinal designations may then be utilized to precisely locate the area of memory into which data or other information was previously written, indicating the current memory locations for current read operations, and to precisely locate the area of memory into which data or other information is to be written next, in order to provide the proper memory location for a subsequent write operation. The ordinal designation also provides for tracking the number of write operations performed in a given memory location, to prevent overuse of a given memory location and concomitant potential loss of data. In the preferred embodiment, the apparatus includes a processor (150) and memory (155), which includes a working memory and a limited write memory.

摘要： A method for providing access by secondary stations (12, 14, 16) to a shared transmission medium, maintains a list of secondary stations (12, 14, 16). A poll is transmitted poll by a primary station (10) to one of the secondary stations (12, 14, 16). The secondary station (12, 14, 16) waits for a poll, examines the transmission allocation, determines if there is congestion and transmits, along with the data in response to the poll, information regarding congestion. A system for providing such access includes a primary station (10) and a plurality of secondary stations (12, 14, 16). The primary station includes a polling controller (30), a receiver (32), a transmitter (34), a summer (36), a secondary station poll list database (38) and a data traffic controller (40).

摘要： Described are computer-based methods and apparatuses, including computer program products, for identifying attackers on a network. A data packet is filtered by a multi-tiered filtering and transmission system. Data packets matching the first tier filter are discarded. Data packets matching the second tier filter are transmitted to an output module based on a criterion. Data packets in the third tier filter are hashed into bins and data packets matching an entry in the bin are transmitted to the output module based on a criterion for the bin. Data packets in the fourth tier transmission system are transmitted to the output module based on a criterion. Data packets that do not meet the criterion for transmission to the output module are transmitted to an attack identification module which analyzes the data packets to identify attacks.

摘要： The system and method provide for efficiently resolving collisions in an environment where a transmitting device cannot hear collisions without a headend control station/control device, i.e., master, repeating transmission of all upstream frames in the downstream direction. This invention also prevents additional collisions from occurring between a device that is retransmitting and a device that is transmitting a packet for the first time. Further, the present invention allows continued utilization of a channel by other devices while contending devices are processing collision resolution procedures.
