摘要： A method supports scalable and reliable multicast in a wireless network with a large bandwidth-delay product. In this method, acknowledgement packets from different receivers experiencing the same number of data packets lost are assigned the same time slots. This method can be combined with other loss recovery techniques, such as forward error correction (FEC) recovery, proactive protection, feedback suppression and collision detection. Scalability is achieved as bandwidth usage relates only to the number of packets transmitted, rather than the number of receivers.

摘要： A data transmission device comprises a transmitter device and a receiver device. The transmitter device divides a data string to be transmitted into an original data string requiring protection against code error and a data string requiring no protection. The transmitter device then carries out an error detection code adding operation and error correction coding at a redundancy code rate of 1/N on the original data string to generate a coded data string. The transmitter device divides the coded data string by N, and outputs the N divided coded data strings and the data string requiring no protection on a communication line under a time division multiplexing control. The receiver device receives the N coded data strings and the data string requiring no protection. The receiver device carries out error correction decoding on the N divided coded data strings and a mixed coded data string obtained by mixing the divided coded data strings, and carries out error detection on decoded data strings obtained by the decoding. The receiver device then outputs one of the decoded data strings from which no code error is detected together with the data string requiring no protection. The data transmission device can carry out a data transmission protecting the transmitted data from burst code errors and random code errors without increase of redundancy.

摘要： For the transmission of variable length coded data blocks, a threshold arithmetic calculation circuit (9) obtains a threshold from an average of the bit lengths of the variable length coded data blocks for each group of such block, and the judgment circuit (10) makes a judgment as to whether or not those variable length coded data blocks have bit lengths exceeding the threshold of the block group to which such data blocks belong. Then, a block divider circuit 11 divides the variable length coded data blocks having bit lengths exceeding the threshold into blocks having small bit lengths. Each block thus obtained is fixedly equalized in bit length to an average length level and transmitted in that condition.

摘要： Under the situation in a network including a transmitter and a receiver in which a transmitter converts a non-compressed packet to be transmitted as a full-header packet including a full header or a header-compressed packet including a compressed header, and sends the converted packet to the receiver, the transmitter sends at least an important packet in the non-compressed packet to be transmitted as a full-header packet. The important packet means for example, a packet containing the data serving an important role when the data terminal eventually receiving each packet reproduces the audio and/or image in accordance with the data in each packet.

摘要： In a fast active scanning wireless network apparatus and method for quick determination of available access points (20), information about a candidate set of available access points (20) is obtained, and a candidate access point is identified from the candidate set. A mobile station (10) then queries the candidate access point with a probe request that designates the candidate access point as a sole responder. The probe request prevents other access points from contending for the medium of communication between the mobile station and the designated sole responder access point by excluding the attempt by other access points (20) to transmit probe responses. The apparatus and method thus increases the probability of a fast and successful probe request from the mobile station and subsequent response from the designated access point (20). The designated access point may also respond with a probe response of high priority, preventing intervention of communication.

摘要： A delay unit 103 adds holding time that has been set by a holding time setting unit 104 to a received data. The holding time is computed based on delay time of received data and the minimum delay time of data received up to a certain point for the purpose of reducing a total delay time. The delay time is estimated in a delay time estimating unit 106 from the difference between a reception time of a packet counted based on an internal clock generator 107 and a time designated by a time stamp in the received packet.

摘要： Cryptographically Protected Prefixes (“CPPs”) are used to create IP addresses, preventing any correlation between a CPP IP address and a host's geographic location. An IP address is subdivided into address prefixes of multiple segments. Each segment is encrypted with a cryptographic key known only to a subset of routers in the access network domain (or Privacy Domain). Therefore, each router obtains the information it needs to forward a packet of information, but not any additional information.
摘要翻译：密码保护前缀（“CPP”）用于创建IP地址，防止CPP IP地址与主机的地理位置之间的任何相关性。 IP地址被细分为多个段的地址前缀。每个段都使用仅在接入网络域（或隐私域）中的路由器的一部分已知的加密密钥进行加密。因此，每个路由器获得转发一个信息包所需的信息，但没有任何附加信息。

摘要： The frame-forming data computing part 101 sorts a plurality of types of parameters forming the frames, and generates frame-forming data that contains data relating to the configuration of said frames and data establishing for each class the error protection method to be applied to each said parameter. The frame-forming data error protection processing part 102 implements the specified error protection for said frame-forming data. The class data error protection processing part 103 implements error protection that is specified for each class according to the frame-forming data, with respect to the parameters that are sorted into a plurality of classes. The synthesizer 104 transmits the frame-forming data that has undergone the specified error protection and the parameters that have undergone the error protection established for each class. In accordance with the present invention, error correction is implemented on frame-forming data indicating the configuration of the frames, and it is also implemented on each class according to the frame-forming data, and these two are synthesized and output. Therefore, it becomes possible to obtain data relating to the configuration of said frames, according to frame-forming data received by the receiving side device. As a result, it is possible to set on the transmission side as desired the content of the error protection to be applied to each class, and in addition, error protection becomes possible for each frame, due to the fact that these data are contained in the frame-forming data, even if the frame has a variable frame length, with the number of bits fluctuating over time.
