Abstract
A method of adaptively classifying information using a binary tree comprises establishing a binary tree including a set of binary sequences each representing one or more network addresses. Once network traffic is received having identifiers describing network traffic sources, the identifiers are correlated to binary sequences within the binary tree. A revision metric is formed based on this correlating, and the binary tree is then revised according to this revision metric. A method of blocking a DDOS attack comprises establishing a binary tree including a set of binary sequences, each of these binary sequences representing one or more network addresses. When network traffic is received having identifiers describing network traffic sources, the identifiers are correlated to binary sequences within the binary tree. Once a DDOS attack notification signal is received, a selected binary tree path within the binary tree is identified as a low cost blocking path within the binary tree. Network traffic correlated to a binary sequence corresponding to the selected binary tree path is blocked.
