A network device for packet flow classification of packet flows received at the network device in a packet transport network, comprising a receiving unit configured for receiving a packet flow; a monitoring and determining unit configured for monitoring said received packet flow during a plurality of consecutive sample time frames, and for determining for each sample time frame thereof a value indicating whether packets have been received; a storing unit configured for storing, after each sample time frame, the determined value in a flow vector storage, and for removing a previously stored value from said flow vector storage, said flow vector storage storing n determined values such as to cover a flow window corresponding with n sample time frames, n being greater than 1; a classifying unit configured for classifying said packet flow using said flow vector storage. |
