The embodiment of the application optimizes the sending logic of the sending detection data packet, adjusts the detection rate in real time according to the response condition of the sending detection data packet, and realizes the dynamic rate adjustment of the sending detection data packet
Corresponding to the disclosed TCP port detection device, the embodiment of the invention also discloses a TCP port detection device method. The TCP port probing method disclosed in the embodiment of the present invention is described in detail below with reference to the TCP port probing apparatus described above.
As shown in fig. 3, specific steps of a TCP port probing method provided in this embodiment of the present application are described in detail below.
Step S11: sending probe packets at a first rate probes all TCP ports.
All TCP ports will be probed by the first sending module 01 sending probe packets at the first rate.
Specifically, the invention can initiate probing to the probing target at a lower rate, and then gradually adjust the probing rate to a higher level, which can help to subsequently adjust the rate of sending the probing packets.
Step S12: the rate adjustment period for sending the probe packets is determined based on an average round trip delay of the TCP port in response to sending the probe packets at the first rate.
Further, after sending the probe data packets to all TCP ports at the first rate, when receiving the first return packet, the value of probe target response RTT (Round-Trip Time Round Trip delay) can be approximately obtained, where RTT is the Time when data is completely sent (the last bit is pushed to the data link) and an acknowledgement signal is received. Taking the obtained round trip time RTT value as a rate adjustment period, and averaging all RTT values of the received data packets in order to prevent occurrence of singular values. According to the embodiment of the application, the RTT (Round-Trip Time Round Trip delay) of the detection target is used as the rate adjustment period, so that the fluctuation of the network can be responded quickly.
Step S13: and determining a rate adjustment reference IP according to the number of the target IP response data packets.
Further, the step S13 specifically includes: and when the response quantity of the TCP ports with the response hosts for sending the detection data packets at the second speed exceeds a preset threshold value, determining the response hosts as reference IPs for regulating the speed of sending the detection data packets.
In this embodiment of the present application, when a data packet returned by a TCP port that is closed by a selected responding host exceeds a preset threshold, the responding host is determined as a reference IP for rate adjustment of sending a probe data packet, because for a host that is closed by a TCP port and does not respond, a sample space is too small to adjust the sending of the probe data packet, and meanwhile, because some firewall policies may cause some TCP ports to respond to the probe data packet at the beginning and not respond after a period of time, the present application determines that the determination condition is "when the number of responses for sending the probe data packet at a second rate by the TCP port that is closed by the responding host exceeds the preset threshold".
Step S14: adjusting the overall probing rate according to the rate adjustment period, so that the probing rate of the TCP port of the reference IP approaches the response rate of the TCP port of the reference IP, where step S14 specifically includes: and determining and adjusting the speed of sending the detection data packets according to the comparison between the number of the response detection data packets of the TCP port needing to be adjusted at the current moment and the sent detection data packets.
Specifically, the speed of sending the detection data packet is adjusted for the TCP port needing to be adjusted in the following mode;
firstly, counting the number of detection data packets sent to a TCP port needing to be adjusted at a first moment as R;
counting the response quantity S of the quantity R of the detection data packets sent to the TCP port needing to be adjusted at the current moment in response to the first moment;
if R is larger than S × Lmax, increasing the detection rate of sending the detection data packet to the TCP port needing to be adjusted according to the rate adjustment period, wherein Lmax is the packet receiving rate when the network condition is good, and Lmax is usually 0.95 (corresponding to five percent of packet loss rate); the new sending probe packet rate is adjusted to the current rate by an adjustment factor, which is usually 1.1.
If R is less than or equal to S X Lmax and R is greater than S X Lmin, the TCP port needing to be adjusted is not adjusted to send the speed of the detection data packet;
and if R < S-Lmin, considering that the network condition is degraded, adjusting the scanning rate to be the current rate/adjustment coefficient, and reducing the detection rate of sending the detection data packet to the TCP port needing to be adjusted according to the rate adjustment period, wherein Lmin is the packet receiving rate of the worst network condition, and Lmin is usually 0.9.
In a specific implementation, for example, 100 packets are sent to a TCP port needing adjustment in one second, and only 96 packets are received in the next second, and since 96> < 100 × 0.95, the scan rate is adjusted to 110 packets per second.
Repeating the above process, when the scanning rate is increased to 1100 data packets per second, transmitting 1100 data packets within one second, finding that only 800 data packets are received in the next second, and 800-straw 1100 × 0.9 indicates that the network quality is degraded, and at this time, adjusting the transmission of 1100 data packets per second to 1000 data packets.
Repeating the above process, and repeating the above calculation process by transmitting packets at the new rate. The scanning speed can be quickly adjusted to the speed approaching the response speed of the target host because the adjusting speed period is very short and the scanning process can be adjusted for many times, and the speed adjusting process of sending the detection data packets is finished after one round of detection is finished on all the TCP ports which need to be adjusted and send the detection data packets.
As shown in fig. 1, before step S11, the method further includes:
step S15: and allocating the TCP ports of the adjacent IP to the same probe group, wherein the number of the TCP ports in each probe group is the same.
Grouping TCP ports to be detected, wherein indexes such as link quality similarity, packet loss rate, RTT and the like of target hosts of adjacent IPs are close to be consistent, and therefore the TCP ports to be detected are grouped in a scanning group.
Compared with the prior art, the embodiment of the invention provides a TCP port detection method and a device, the detection data packet is sent at a first speed to start the TCP port detection of a target IP, then the speed regulation period for sending the detection data packet is determined according to the round-trip delay, the rate regulation reference IP is determined according to the number of the data packets responded by the target, the overall detection rate is regulated according to the rate regulation period, so that the port detection rate of the reference IP approaches the port response rate of the reference IP, and the detection of all targets is optimized. By adjusting the sending rate of the detection data packet for a plurality of times, the sending rate of the detection data packet approaches the response rate of the target, thereby reducing packet loss and accelerating the scanning speed. According to the embodiment of the application, the sending logic for sending the detection data packet is optimized, the detection rate is adjusted in real time according to the response condition of the detection data packet, the packet sending rate is prevented from far exceeding or far being smaller than the response capacity of a network and a target, and the accuracy and the efficiency of detection are effectively improved.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
