    摘要： A server/overlay network architecture and related method prevent (i.e., minimize the likelihood of) overloads from many network clients all trying to upload data files to a common destination server on the network at about the same time. Before a client transfers its (his or her) data file to the common network destination, a unique identifier (generally much smaller than the data itself) for the data of that client is generated. The unique identifier, such as a one-way hash function, is transmitted to an authenticator trusted by the common destination. The authenticator time-stamps (i.e., stores time and date) the unique identifier, digitally signs a message incorporating the unique identifier and the time-stamp and sends the message to the client who sent the unique identifier. The client then sends the data file with its time stamp to one of a plurality of upload proxy servers. The proxy server sends a message to the common destination telling it to pick up the data file when ready. The common destination server thus avoids being overloaded by many clients transferring their rather large data files to it at the same time. The common destination server can check the time-stamp and unique identifier to insure that the data has not been altered after the time-stamp.

    摘要： In applications where data is transmitted in frames of symbols and the transmission medium is such that the probability of correct reception of symbols is, on the average, not uniform for different symbols in a frame, transmission of test frames enables creation of information about the different probabilities of correct reception, and that information is employed by the transmitter to control the manner in which symbols are transmitted so as to ameliorate the effects of the different probabilities of correct reception.

    摘要： A denial-of-service network attack detection system is deployable in single-homed and multi-homed stub networks. The detection system maintains state information of flows entering and leaving the stub domain to determine if exiting traffic exceeds traffic entering the system. Monitors perform simple processing tasks on sampled packets at individual routers in the network at line speed and perform more intensive processing at the routers periodically. The monitors at the routers form an overlay network and communicate pertinent traffic state information between nodes. The state information is collected and analyzed to determine the presence of an attack.

    摘要翻译： 服务器/覆盖网络架构和相关方法防止（即最小化许多网络客户端的重载的可能性），所有这些都试图将数据文件在大约相同的时间上传到网络上的公共目的地服务器。 在客户端将其（他或她）的数据文件传输到公共网络目的地之前，生成该客户端的数据的唯一标识符（通常远小于数据本身）。 诸如单向散列函数的唯一标识符被发送到由公共目的地信任的认证器。 认证者时间戳（即，存储时间和日期）唯一标识符，对包含唯一标识符和时间戳的消息进行数字签名，并将消息发送给发送唯一标识符的客户端。 然后，客户端将具有其时间戳的数据文件发送到多个上传代理服务器之一。 代理服务器向公共目的地发送消息，告知它在准备好时接收数据文件。 因此，公共目的地服务器避免了许多客户端将其相当大的数据文件传输到它的同时过载。 公共目的地服务器可以检查时间戳和唯一标识符，以确保在时间戳之后数据未被更改。
