Wherein, described start node device also for when sending test packet, is sequentially written in self UID data in described equipment UID record cell;
Wherein, described intermediate node device is also for after the test packet receiving last layer node or the transmission of next node layer, and the equipment UID record cell to this test packet is sequentially written in self UID data;
Wherein, described destination node device is also for after the test packet receiving the transmission of last layer node, and the equipment UID record cell to this test packet is sequentially written in self UID data;
Wherein, described start node device also for drawing the transmission path of test packet according to the UID of journal in equipment UID record cell, and then draws whether to be communicated with between start node with destination node and to disconnect when not being communicated with after that node.
7. network situation detection system according to claim 5, is characterized in that:
Described start node device is sending test packet 15000-25000 time continuously or is stopping sending test packet after sending 1-2 hour continuously, then judges network condition by the test packet of returning.
8. network situation detection system according to claim 5, is characterized in that:
Described start node device judges network condition according to the data of IP address record cell, transmitting time record cell and time of reception recording unit records, specifically:
Draw the transmission path of test packet according to the IP address of journal in the record cell of described IP address, and then draw whether be communicated with between start node with destination node and disconnect when not being communicated with after that node;
Draw the transmission time between each node according to the time of reception of journal in the transmitting time of journal in described transmitting time record cell and time of reception record cell, and then judge network speed and draw Internet Transmission bottleneck node.
