1. safeguard a method for TCP flow list structure and out of order buffering area, it is characterized in that:

  • step is as follows;

    A, according to memory headroom size and purposes, by record link information space address stored in link address pond, will the address of out of order link information be recorded stored in out of order buffer zone address pond;

    After B, system initialization, from link address pond and out of order buffer zone address pond, read 2K address respectively stored in two FIFO buffer queues;

    When C, newly-built connection, from link address queue, take out an available address, and link information is write the buffering area pointed to this address;

    If D connects out of order, from out of order buffer queue, take out an available address, submit to out of order reordering module to process this address and out of order link information;

    When E, connection disconnect, the link address and out of order buffer zone address of distributing to this TCP connection are recovered to and receive in release address buffer queue;

    F, the inspection fast spacing wave of available address queue and the fast of release address queue expire signal, if available address queue is empty soon, from address pool, get address, if release address queue soon completely, reclaims address in address pool.
