ABSTRACT:
The invention relates to packet tracing in computer networks. Data packets are captured when entering or exiting the network or at any point within the network protocol stack. Buffers in computer kernel space memory store the packets until the contents of the buffers are written to persistent memory. Each buffer holds one or more data packets and the contents of a buffer are written to persistent memory when a status flag associated with the buffer indicates that it may hold no further packets. Data packets may be continuously captured, or capture may be initiated and/or terminated in response to a special event.
