摘要： The invention provides methods, apparatus and systems for detecting distributed denial of service (DDoS) attacks within the Internet by sampling packets at a point or points in Internet backbone connections to determine a packet metric parameter. The packet metric parameter which might comprise the volume of packets received is analyzed over selected time intervals with respect to specified geographical locations in which the hosts transmitting the packets are located. The expected behavior can be employed to identify traffic distortions revealing a DDoS attack. In a complementary aspect, the invention provides a method of authenticating packets at routers in order to elevate the QoS of authenticated packets. This method can be used to block or filter packets and can be used in conjunction with the DDoS attack detection system to defend against DDoS attacks within the Internet in a distributed manner.

摘要： There are introduced ways for retrieving or depositing a replica of an electronic document in a computer network. After having selected at least one replica number, a given function is applied. The function requires as input the replica number and a document identifier. The function returns as a result at least one entity identifier, each entity identifier representing an entity in the network that might provide the replica. In a next step, a document related request is addressed to at least one of the identified entities.

摘要： A method for converting a signal, including the steps of: providing a first representation of the signal in a first domain; converting the first representation of the signal into a second representation of the signal in a second domain, by applying a transform involving a Haar transform and a Hadamard transform, such that a basis of the second domain is maximally incoherent to a Haar basis. The signal is converted to a domain whose basis is maximally incoherent to a Haar basis. Yet, it is not required to convert the input vector representing the signal to a Haar basis first. This allows reducing the number of steps which increases conversion efficiency. Accordingly, obtaining the structure of the signal requires fewer samples.
摘要翻译：一种用于转换信号的方法，包括以下步骤：在第一域中提供信号的第一表示; 通过应用涉及Haar变换和Hadamard变换的变换，将信号的第一表示转换为第二域中的信号的第二表示，使得第二域的基础最大程度上不相干于Haar。该信号被转换为一个域，其基数最大程度地与Haar不相符。然而，不需要首先将表示信号的输入向量转换为Haar。这允许减少提高转换效率的步骤数量。因此，获得信号的结构需要更少的采样。
