Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The embodiment of the invention provides a method and a system for measuring the speed of a home gateway CPU (Central processing Unit), wherein a plurality of data packets are packaged into one by hardware and then sent to a network card protocol module for reconstruction and packet return, so that the influence of the environment on the speed measurement can be reduced.
In order to achieve the technical effects, the general idea of the application is as follows:
establishing TCP connection with a speed measurement server, determining quintuple information of a speed measurement data packet sent by the speed measurement server, configuring the speed measurement data packet, and receiving the speed measurement data packet to a network card;
enabling an LRO (line replaceable operation) by the network card, packaging the network card into a transmission data packet when the network card receives N speed measurement data packets, wherein N is an integer greater than 1, and sending the transmission data packet to a network card protocol stack; the network card protocol stack receives the transmission data packet, unpacks the transmission data packet into N speed measurement data packets according to quintuple information, obtains N response data packets by the speed measurement data packet through ACK response of the network card protocol stack, sends the response data packets to the network card, and accumulates the receiving data length L of the speed measurement data packets; the network card starts the LSO to return a response data packet to the speed measurement server;
and (4) obtaining the length L of the received data twice at an interval of time T, and calculating the data transmission rate of the network card according to the change of the L.
In the transmission of gateway data packets, bandwidth rate testing can be affected by various factors, including uplink and downlink messages of other non-download servers combined with data path optimization of a protocol stack, where the optimization causes the test data packets to need to go through the protocol stack interactively, which further causes data path extension, and is finally susceptible to rate instability caused by environmental factors. Meanwhile, the data packet transmission needs a plurality of ports for interaction and transmission, and the interaction also takes more time, thereby affecting the accuracy of the test. After receiving the test data packets from the test server, the invention encapsulates the data packets into big packets and sets the special channels for the speed measurement data packets, thereby reducing the interaction flow and the flow path of the data packets, further reducing the influence of the environment on transmission and improving the data test effect.
In order to better understand the technical solution, the following detailed description is made with reference to specific embodiments.
Referring to fig. 1, an embodiment of the present invention provides a method for measuring a speed of a home gateway CPU, including:
s1: establishing TCP connection with a speed measuring server;
s2: determining quintuple information of a speed measurement data packet sent by a speed measurement server, configuring the speed measurement data packet, and receiving the speed measurement data packet to a network card.
In steps S1 to S2, after the TCP connection with the speed measurement server is completed, the home gateway can be ensured to directly take over the established TCP interaction through the network card by determining the quintuple information in the speed measurement data packet, thereby reducing the data path transmission distance and reducing the message interaction times. Furthermore, the invention also configures a speed measurement data packet to be capable of being packaged at the network card hardware, the test server sends the speed measurement data packet to the network card and packages the speed measurement data packet through the network card, CPU interruption is reduced, and after the packaging is finished, the transmission time of a plurality of data packets is reduced by only transmitting one big packet within the same time, so that the speed measurement performance in unit time can be larger, the network card performance is greatly utilized to reduce CPU resource consumption, and the CPU time slice processing is optimized.
Specifically, as shown in fig. 2, the establishing of the TCP connection with the speed measurement server in step S1 includes:
s101, receiving a speed measurement parameter by an application state;
and S102, downloading the speed measurement data packet from the speed measurement server in the application state.
And S103, removing the time stamp in the speed measurement data packet by the application state, interacting with the TCP of the speed measurement server for the first time, and establishing TCP connection.
At the test place, the home gateway and the test server will communicate and exchange the speed measurement parameters, and then the speed measurement is started. The invention is configured to receive the speed measurement parameters through the application state of the home gateway, complete the interaction with the speed measurement server and further download the speed measurement data packet from the speed measurement server. And have redundant information such as this timestamp in the data package tests the speed, consequently, the configuration is used the state and is got rid of the timestamp in the data package that tests the speed, rejects useless information in the data package, can effectively reduce the size of data package, reduces data transmission's pressure, and the data package diminishes simultaneously makes its transmission completion time faster, tests the speed more accurate, efficiency. Further, the data packets are TCP packets, and when the N data packets are encapsulated into one transmission data packet through the network card, an echo command is called to remove a timestamp field in the TCP packet.
The transmission data packet is directly sent to the network card protocol stack without being processed by the LINUX protocol stack, so that the influence on normal data message processing of the home gateway due to shielding hook processing in the home gateway service due to the fact that the data message is processed by skipping two layers and three layers NETFILTER HOOK in BRIDGE and ROUTE for optimizing the rate downloading performance is avoided.
Further, as shown in fig. 3, in step S2, determining quintuple information of a speed measurement data packet sent by the speed measurement server, and configuring the speed measurement data packet includes:
s201, a kernel mode receives a speed measurement data packet and quintuple information from an application mode;
s202, the kernel mode learns the quintuple information and configures that a subsequent speed measurement data packet is received by the network card according to the quintuple information;
wherein, the configuration is according to quintuple information, and subsequent speed measuring data packet is received by the network card, including:
S202A, judging whether the target IP in the speed measurement data packet is the same as the target IP of the target quintuple information;
S202B, judging whether the PROTOCOL types of the messages in the speed measurement data packet are the same as the target types of the target quintuple information;
if the data packets are the same, the message in the data packet is a TX ACK TCP message, and subsequent TCP message interaction is set to be processed by the network card without going through a protocol stack.
In the conventional gateway speed measurement, a transmission path of a speed measurement data packet is not usually directly specified, and the speed measurement data packet can be transmitted to a target address after being transferred and stored and waited for by a relatively complex process. Therefore, the configuration kernel mode receives the quintuple information from the application mode and further learns the quintuple information, and a path is appointed for the speed measurement data packet according to the learned content, namely, the subsequent speed measurement data packet is directly received by the network card and is not influenced by the path, protocol decision and the like, so that the unreal speed measurement result caused by unsmooth transmission is avoided.
It should be noted that, the kernel mode used in the present invention is a hardware resource for controlling a computer in an operating system, and provides an environment for running an upper application program; the user mode is an activity space of an upper application program, and the execution of the application program must depend on resources provided by a kernel, including CPU resources, storage resources, I/O resources and the like.
S3, starting the LRO by the network card, packaging the network card into a transmission data packet when the network card receives N speed measurement data packets, wherein N is an integer greater than 1, and sending the transmission data packet to a network card protocol stack; the network card protocol stack receives the transmission data packet, unpacks the transmission data packet into N speed measurement data packets according to quintuple information, obtains N response data packets by the speed measurement data packets through ACK response of the network card protocol stack, sends the response data packets to the network card, and accumulates the receiving data length L of the speed measurement data packets; and the network card starts the LSO to return a response data packet to the speed measurement server.
The invention further configures the network card to package the hardware, unpacks the software, and configures the path of the speed measuring package transmitted in the network card to be transmitted from the network card to the network card protocol stack. The designated path saves the judgment of a data packet transmission path, the packet unpacking saves the transmission time of the data packet, the data packets are not required to be independently interacted and transmitted but are sent together, and the time slice of the CPU can better arrange and finish the transmission of the data packet.
And the network card enters an LRO mode and combines the N data packets into one transmission data packet.
In an LRO (Large Receive Offload) mode, a plurality of received TCP data are aggregated into a Large data packet and then transmitted to a network protocol stack for processing, so as to reduce the overhead of an upper protocol stack and improve the capability of a system to Receive the TCP data packet. The encapsulation of each data packet of N can be more effectively finished, and a transmission data packet after shaping is transmitted out. Meanwhile, manpower and material resources for manual setting and maintenance of personnel are reduced.
And packaging the ten packets into a big packet at the hardware through an LRO mechanism, transmitting the big packet to a network card protocol stack, analyzing and unpacking the message according to the quintuple information after the big packet reaches the network card protocol stack, and reconstructing the message after unpacking to complete TCP (transmission control protocol) packet return. The method can effectively reduce the process of transmitting the packet interactive process with N data numbers to one packet.
Further, after receiving the speed measurement data packet, the invention starts to accumulate the data length L of the speed measurement data packet, so as to facilitate the subsequent gateway speed test.
Specifically, as shown in fig. 4, the receiving, by the network card protocol stack, the transmission data packet, and unpacking the transmission data packet into N speed measurement data packets according to quintuple information, where the speed measurement data packet obtains N response data packets through an ACK response of the network card protocol stack, and the method includes:
s301, a network card protocol stack receives the transmission data packet;
s302, unpacking the transmission data packet into N speed measurement data packets according to quintuple information;
s303, initializing response ACK configuration, and if the source IP address in the speed measurement data packet is a speed measurement server configuration address and contains a TCP message, acquiring the attribute of the speed measurement data packet, wherein the attribute comprises whether VLAN and IPOE/PPPOE protocol types are supported;
s304, reassigning the ACK _ NUM according to the attribute of the speed measurement data packet, and inserting the message serial number into the head of the reconstructed message to obtain a response data packet.
And after receiving the transmission data packet, the network card protocol stack further unpacks the transmission data packet according to the quintuple information, and further processes and reconstructs the transmission data packet according to the attribute of the speed measurement data packet to obtain a response data packet.
Finally, the speed measurement server is returned in the form of N data packets, that is, messages with the address of the speed measurement server as a source address and a destination address are optimized and judged, so that the speed measurement data packets can be subjected to speed test through the home gateway under the condition that the speed measurement data packets are not influenced by other protocols and the environment of the data packets.
It should be noted that the attribute of the speed measurement data packet is specifically a parameter for determining the type of the speed measurement data packet, and if the speed measurement data packet supports the VLAN and IPOE/PPPOE protocol types, the gateway can adjust the description content in the data packet according to the attribute/parameter of the speed measurement data. For example, the gateway can reassign the serial number of the velocity measurement data packet according to whether the gateway is provided with a VLAN or not and the difference of types of IPOE/PPPOE protocols, and increase the number of the received velocity measurement data packets, thereby reconstructing the message header of the message corresponding to the velocity measurement data packet.
S4, obtaining the length L of the received data twice at intervals of time T, and calculating the data transmission rate of the network card according to the change of the L
In summary, the steps S1 to S4 directly assign the speed measurement packet sent by the server to a path inside the gateway, and directly perform configuration processing, so as to avoid the influence of most protocols such as waiting and forwarding, reduce the influence of congestion of other upper and lower messages, and ensure the accuracy of speed measurement of the gateway.
For example, as shown in fig. 5, the speed measurement includes the following steps:
t1, the gateway software starts to read the length of the real-time received message, and the process goes to T2;
t2, the gateway software creates an AF _ INET mode socket, generates a handle and turns to T3;

It should be noted that ioctl (input/output control) is a system call dedicated to the input/output operation of a device, and the call is transmitted to a request code associated with the device, and the function of the system call depends entirely on the request code. And an Ioctl interface is an independent system call through which user space can communicate with the device driver. The request for the device driver is an Ioctl call with the device and request number as parameters, so the kernel allows the user space to access the device driver and then the device without knowing specific device details, and without requiring a large heap of system calls for different devices. Other kernel-mode/user-mode communication tools besides ioctl are also applicable, such as Netlink, etc., and the inventor is merely exemplified by ioctl, it being understood that the general and detailed descriptions are exemplary and explanatory only and are not restrictive of the present application.
