Description
Technical Field
The present application relates to the field of internet technologies, and in particular, to a method and a system for checking and accepting a network node.
Background
In the internet, whether delivery of network nodes meets expectations or not is checked, whether bandwidth of the network nodes meets expectations or not is checked, and acceptance tests are often performed by using a C/S (client/server) tool. And in the test acceptance process, the bandwidth of the node needs to be filled, and after the expected bandwidth flow of the node is filled, the packet loss and transmission quality condition of the node are verified. Due to the fact that the C/S mode is used, corresponding software needs to be installed on the client side and the server side for testing, steps are complex, and when a node with large bandwidth needs to be tested, the number cost and the bandwidth cost of the target drone are high, efficiency is low, and time consumption is long.
Taking the test tool iperf as an example, when the C/S tool is used for pressing, a target machine (serving as a server) and an attack machine (serving as a client) are required, and the attack machine (client) sends a large amount of packet sending requests to the target machine (server). The prior art in this case has the following disadvantages:
(1) the target side (server side) is costly. The target machine end (server end) with the same bandwidth size as the attacking end node is adopted. If the attack end (client) has 100G bandwidth, the server end needs to prepare 100G bandwidth bearing capacity, and if the bandwidth bearing capacity is calculated according to 1G quintuple RMB, 50W bandwidth cost of the server end is consumed.
(2) The steps are cumbersome. Each machine at an attack end (client) needs to install iperf service, each machine at a target end (server) also needs to install the service, IPTABLES is closed and a monitoring port is opened, and after the test is finished, the corresponding monitoring port is closed and the IPTABLES is opened.
(3) The test time is long, the test quantity cannot be controlled, and the cost is high. The nodes at the target drone end (service end) need to be switched away for service and volume reduction. The time of the reduction process is long, and the normal use of the target drone node is influenced. The bandwidth of a single server of an attack end (client) needs to be fully filled and cannot be changed.
(4) The target side (server side) IP requirement is difficult. The target machine end can be controlled only by completely controlling the IP quantity and the bandwidth quantity by selecting the same province or adjacent provinces and ISP target machine end.
(5) Is vulnerable to being treated as an attack, resulting in the attacker (client) node machine being sealed. When the bandwidth is pressed, an attacking terminal machine can send a large number of packet sending requests to a target machine terminal (server terminal), similar to TCP SYN FLOOD attack, an IDC machine room and an operator can consider that a network node is attacked, and under the condition, the attacking terminal node is sealed if necessary, and is penalized if relevant laws and regulations are violated if necessary.
Therefore, there is a need for an efficient network node acceptance method and system.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
In the prior art, when a C/S (client/server) tool is used for acceptance test, the bandwidth of a node needs to be filled, and after the expected bandwidth flow of the node is filled, the packet loss and transmission quality of the node are verified. Due to the fact that the C/S mode is used, corresponding software needs to be installed on the client side and the server side for testing, steps are complex, and when a node with large bandwidth needs to be tested, the number cost and the bandwidth cost of the target drone are high, efficiency is low, and time consumption is long.
In order to solve the above problems, the present application proposes an innovative method of accepting network nodes. In the method, the press test acceptance can be carried out under the condition of no person on duty completely by only inputting the name of the network node to be accepted and the tested bandwidth information, and the node acceptance result is notified to the relevant responsible person.
In the application, the global management center is responsible for intelligent control of the strategy scheme, a packet sending scheme is generated according to a received node acceptance task, the packet sending scheme is issued to the intelligent packet sending module, the related information and the formula of the intelligent packet sending module calculate the number of data packets to be sent, the size of each data packet, which line to send out, the execution time, the packet loss acquisition module and the quality score acquisition module are triggered to start acquisition, the quality score data, the packet loss data and the like are reported to the global management center at regular time, and the bandwidth acquisition module reports the bandwidth information to the global management center. The global management center integrates the data to generate acceptance data, node detection results under several package sending schemes are finally obtained, the results are stored in the global management center, and the message notification module pulls acceptance result information of the node from the global management center and notifies the information to a node constructor.
The application provides a method for checking and accepting a network node, which comprises the following steps:
102, establishing a packet-sending IP library, generating a data packet by using the IP in the packet-sending IP library and the packet-sending strategy information, and sending the data packet to a corresponding target IP;
and 103, acquiring transmission quality data of the network node to be checked, grading the node quality based on the transmission quality data, and acquiring a network node checking result based on the node quality grade.
The operator responsible for checking and accepting the network node submits a network node checking and accepting task to the global management center, the global management center receives the network node checking and accepting task information, and the network node checking and accepting task information at least comprises: the network node name to be checked and accepted, the pressure measurement bandwidth, the pressure measurement line and the pressure measurement time. The global management center generates package sending strategy information based on the information, wherein the package sending strategy information at least comprises the following components: and receiving the single machine bandwidth, the single machine voltage measuring circuit and the single machine voltage measuring time of the network node to be checked.
And the intelligent packet sending module receives the packet sending strategy information from the global management center, generates a data packet based on the packet sending strategy information and sends the data packet to a corresponding target IP.
In step 101, generating packet-sending policy information based on the received network node acceptance task includes: and after receiving the network node acceptance task information, carrying out network node correctness verification and network node safety verification on the network node acceptance task.
And after receiving the acceptance task from the operator, the global management center checks the network nodes related to the task, including correctness checking and safety checking. And firstly, checking the correctness of the node, and then checking the safety of the node after the check is passed.
The correctness check is to submit a POST request to the resource management interface, wherein the request carries parameters such as network node names and the like so as to judge whether the network nodes exist in the resource management platform, the node bandwidth size and whether the submitted line is consistent with the information when the information is recorded. If the verification is not present or is not consistent with the input, the verification fails.
The security check is divided into analysis check and flow check, so that whether the network node can perform pressure measurement check at present is determined, and the pressure measurement of the nodes served on line is prevented, so that the service quality of customers is influenced. Specifically, a POST request based on the network node name and POST requests of all IPs of the network node are submitted from the traffic management interface and the DNS resolution interface, and whether security verification can be passed is determined according to the size of the node traffic and whether resolution exists. If the node flow is less than the set threshold, for example, 100M marks the flow check to pass, if all the IPs of the node are not marked in the DNS resolution by the resolution check to pass.
In step 101, generating packet-sending policy information based on the received network node acceptance task further includes: when the network node correctness check and the network node security check both pass, judging whether the network node acceptance task comprises pressure measurement of a single operator line of the network node or multiple operator lines of the network node, and generating acceptance criteria and package sending strategy information for the single operator line or the acceptance criteria and package sending strategy information for each operator line in the multiple operator lines.
After the correctness check and the safety check of the network node by the global management center are passed, whether the network node involved in the acceptance task is a single line or a plurality of lines, namely a single operator line or a plurality of operator lines of the network node is judged. If the node is a single-line node (single operator line), directly generating acceptance criteria and package sending strategy information; if the multi-line (with a plurality of operator lines) is adopted, the system prompts a line appointed to select pressure measurement acceptance, and an operator selects single-line pressure measurement or multi-line simultaneous pressure measurement each time (if the multi-line simultaneous pressure measurement acceptance is not selected, all the operator lines perform pressure measurement acceptance by default) and generates acceptance criteria and package sending strategy information aiming at the plurality of lines.
The acceptance criteria may be given in the form of a standard mapping table. For example, the construction bandwidth of the input node is 100G, the name of the network node is dx-yd-guizhou-guiyang-jd-6, the node pressure measurement time is 30min, and the pressure measurement line is a double line; the standard mapping table generated is as follows:
a.A rating: the bandwidth reaches more than 96G (more than 96%), the packet loss rate is within 1%, and the quality score is more than 90 points;
b.B rating: the bandwidth reaches 93-96G (93% -96%), the packet loss rate is within 1%, and the quality score is within 80-90;
c.C rating: the bandwidth reaches below 93G (less than 93%), the packet loss rate is greater than 1% or the quality score is below 80 points;
..
The hair-bag scheme is exemplified as follows: submitting the tasks of checking and accepting the telecommunication and the mobile Guiyang node 6, wherein the telecommunication bandwidth is n, the mobile bandwidth is m, and the unit is G.
The reference scheme formula of the package sending scheme of the Guiyang node is as follows:
y＝(k*a)/x，
wherein the dependent variable y represents the bandwidth printed by a single machine; a is a bandwidth percentage, is a value determined according to actual needs, can support self-adjustment, and is used for node quality grade or gear division and generation of a packet sending scheme of a corresponding gear, for example, default fixed values are as follows: 96%, 93%, 90%, 80%, 60% and 50%, selecting the 6 gears from the fixed list one by one for 1 time, and testing the node quality data of each gear. k is the total bandwidth of the node; the dependent variable x represents the number of machines selected by the node.
And 6 packet sending schemes are generated according to the bandwidth percentage value quantity:
f1: telecom-y 1 (G/stage), where y1 ═ (n × 96%)/x, mobile-y 2 (G/stage), where y2 ═ (m × 96%)/x measured time: 5 min;
f2: telecom-y 1 (G/stage), where y1 ═ (n × 93%)/x, mobile-y 2 (G/stage), where y2 ═ (m × 93%)/x measured time: 5 min;
f3: telecom-y 1 (G/stage), where y1 ═ (n × 90%)/x, mobile-y 2 (G/stage), where y2 ═ (m × 90%)/x measured time: 5 min;
f4: telecom-y 1 (G/stage), where y1 ═ (n × 80%)/x, mobile-y 2 (G/stage), where y2 ═ (m × 80%)/x measured time: 5 min;
f5: telecom-y 1 (G/stage), where y1 ═ (n 60%)/x, mobile-y 2 (G/stage), where y2 ═ (m 60%)/x measured time: 5 min;
f6: telecom-y 1 (G/stage), where y1 ═ (n × 50%)/x, mobile-y 2 (G/stage), where y2 ═ (m × 50%)/x measured time: and 5 min.
Where n represents the telecommunications bandwidth of the node and m represents the mobility bandwidth of the node.
The packet sending scheme (namely packet sending strategy information) comprises node single machine bandwidth, single machine voltage measuring circuit and single machine voltage measuring time. And after generating the package sending strategy information, the global management center sends the package sending strategy information to the intelligent package sending module.
In step 102, the building of the packet IP library includes: and acquiring an IP list belonging to an operator to which the single voltage measuring line belongs on the basis of the single voltage measuring line, and selecting an IP which passes through the gateway of the network node to be checked and received but is not communicated with the gateway in the IP list to establish the packet sending IP library.
Here, the principle of the intelligent packet sending module is to send only data packets but not to establish a connection, so that the three-way handshake and four-way disconnection processes for establishing a connection are bypassed. Specifically, the building of the transmission packet IP includes: pulling an IP list from a public network IP interface aiming at an operator of a pressure measurement line; and circularly traversing to judge whether each IP passes through the gateway of the pressure measurement node and is accessible to the gateway, and selecting the IP which passes through the gateway and is not accessible to generate an IP list for different operators. The reason for this is: on one hand, all data packets can be ensured to be sent out from the outlet of the switch; on the other hand, the sent data packet does not affect the normal communication service in the internet, because if the data packet is an IP connected with the gateway, the normal service of the IP may be affected.
In step 102, generating a data packet by using the IP in the packet-sending IP library and the packet-sending policy information includes: determining the size of the data packet; and calculating the number of the data packets based on the size of the data packets and the single bandwidth of the network node to be checked and received, and generating the data packets based on the size of the data packets, the number of the data packets and the IP list.
Specifically, the generating a data packet and sending the data packet to a corresponding target IP by using the IP in the packet sending IP library and the packet sending policy information includes: generating data sets of the calculated number of data packets, wherein the size of each data set is equal to the size of the determined data packet, and constructing a header for each data set based on set parameters; selecting a target IP for each data message from the packet-sending IPs, and encapsulating each target IP and the corresponding data set and the header into a data packet; and sending the data packet to a target IP contained in the data packet.
And after receiving the packet sending strategy information sent by the global management center, the intelligent packet sending module generates a data packet by using the generated IP list and the packet sending strategy information. The process of generating the data packet includes the following steps (taking the transmission of a TCP data packet as an example):
(1) TCP message with encapsulation structure
This step in turn comprises 3 steps: a) according to the data structure of the TCP, randomly selecting some reasonable parameters to construct a TCP header; b) determining the size of the data packets, calculating the number of the data packets according to the received single-machine bandwidth quantity and a formula, and then constructing the data packets with the specified size; c) and encapsulating the TCP header and the data part to form a complete TCP message.
The number of packets is calculated by: n BW/(b × S), where b is a constant, a suitable value can be determined by simulation testing. S is the size of the transmitted packet, S takes the value automatically in [0,1452], which is determined by the protocol, S generally defaults to 1452, 1452 being the maximum load value of 1 TCP packet, where S may be an empirical value determined by simulation testing. BW is the node standalone bandwidth. The total amount of the data packets sent by the single station can be calculated according to the total bandwidth of the single station sending packets and the size of the single station sending packets. If the calculated N is not an integer, the size of one data packet (data set) can be reduced accordingly, so that the sum of the sizes of all the constructed data packets is equal to the total bandwidth value of the single machine to be tested.
(2) Constructing IP message, sending TCP data packet
And constructing and packaging a required TCP message according to the calculated size of the data packet to be transmitted, combining the received pressure measurement information, selecting an IP from a corresponding IP list according to a pressure measurement line to package the IP message, and then adding the packaged IP message into a transmission queue for transmission. Here, the IP may be selected randomly from an IP list.
When there are multiple pressure measurement lines, a line mapping table may be generated to facilitate IP selection, for example, the line mapping table relationship is as follows:
a telecommunications line IP library 1;
a mobile line IP library 2;
a communication line IP library 3;
and so on.
Therefore, when the node is checked and accepted, a plurality of data packets are generated, the total size of the data packets is the same as the size of the bandwidth of the node, and the data packets are sent to the IP address encapsulated in the data packets. Thus, the data packets can be sent out from the nodes, and the full-load operation of the single node is tested. However, since the IP of these extranets is not configured to the actual server, this bypasses the 3-way handshake and 4-way disconnection process of TCP, and also does not require the actual target server as long as the target IP is available. Also for this reason, in the present application, no waste of bandwidth is generated.
The traditional mode in the prior art is as follows: sending out the data packet, then requiring the target IP and the server to receive the sent data packet, then marking the node outlet bandwidth to a set threshold value, after reaching the threshold value, selecting the available IP according to the strategy to establish an IP base, wherein an actual server is required to configure the IPs on the server. Therefore, in the prior art, the process of checking the quality condition of the node needs to go through 3 handshakes to establish connection, send data packets and disconnect 4 times.
Therefore, the method simplifies the operation steps, improves the acceptance efficiency, releases the occupation of the line to be accepted and saves the labor cost.
In step 103, the acquiring the transmission quality data of the network node to be checked at least includes:
and acquiring the flow bandwidth per minute, packet loss information per minute and average download speed per minute of the single machine on the network node to be checked.
Specifically, the bandwidth acquisition module can acquire the traffic bandwidth of the edge single machine and report the real-time bandwidth information to the global management center according to the minute granularity; the packet loss information of the edge single machine can be acquired by a packet loss acquisition module, and the packet loss information is reported to a global management center according to minute granularity; the average download speed of the url accessed in 1 minute can be calculated by the quality scoring module from the access log and the system kernel. Furthermore, the downloading speed within the current 1 minute can be compared with the downloading speed within the previous 1 day and the same time period, the variation is calculated, the quality score is obtained, and finally the score result is reported to the global management center. If the pressure measurement circuit comprises a plurality of circuits, the acquisition module can acquire scores of the plurality of circuits respectively and report the score results to the global management center.
In addition, the message channel module can also receive the result information of the node acceptance quality from the global management center and inform the corresponding network constructor of the result information.
The positions of the modules may be set according to actual conditions, and the modules may be arranged in a centralized manner or in a distributed manner. For example, the intelligent packet sending module is located on a node server because a data packet needs to be sent from a node, the bandwidth acquisition module can also be located on a node server of a network, the global management center can be located on a central server, the packet loss acquisition module and the quality scoring module can be located on an independent data analysis server, the message channel module can also be located on an independent server as an independent module, and an interface of the message channel module can be directly called when the message channel module is used.
A specific embodiment according to the present application is described in detail below, which comprises the following steps:
step one, an operator submits a network node acceptance task to a global management center.
And step two, after receiving the node acceptance task, the global management center generates packet sending strategy information based on the network node name to be accepted, the pressure measurement bandwidth, the pressure measurement line and the pressure measurement time, wherein the packet sending strategy information comprises the stand-alone bandwidth, the stand-alone pressure measurement line and the stand-alone pressure measurement time of the network node to be accepted.
