Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.
Fig. 1 is a schematic flowchart of a method for implementing accelerated forwarding according to an embodiment of the present invention.
The embodiment of the invention provides a method for realizing accelerated forwarding, which comprises the following steps:
and S10, reading all connection tracking information. Wherein the connection tracking information comprises: source address, source port, destination address, destination port, and protocol number. The connection tracking information may further include: extension information, private information of each protocol.
It should be noted that, the connection tracking mechanism generates a new connection record (connectioncontrontrack) for the data packet passing through the network stack by Linux. Thereafter, all packets belonging to the connection are uniquely assigned to the connection and identify the status of the connection. Connection tracking is the basis of state detection of a firewall module and is also the premise for realizing SNAT and DNAT in address conversion. Hardware accelerated forwarding functionality requires software to assist in the implementation of the hardware. And the software reads the connection tracking information from the operating system, fills the information into the hardware according to the requirement of the hardware, and finishes the acceleration of the network flow. In the embodiment, all the connection tracking information is acquired, analyzed and screened at one time, and the tracking connection information does not need to be read, judged and refilled into hardware one by one, so that the waste of calculation resources during filling is avoided. And the problem that the connection trace information with large flow is filled into hardware after the connection trace information with small flow is avoided. In this embodiment, the communication device is described by taking a router as an example, and may be another communication device.
And S20, screening the connection tracking information according to a preset flow screening condition.
In a preferred embodiment, the screening the connection tracking information according to a preset traffic screening condition in step S20 specifically includes:
and screening the connection tracking information according to the flow per second and the forwarding pressure of the connection tracking information. It should be noted that the preset traffic screening condition may also be set according to the hardware configuration of the router itself.
In this embodiment, in the process of reading the connection trace information or after all the connection trace information is read, the connection trace information is screened (the screening may be performed by sorting the connection trace information according to the flow rate or by stacking, which is not limited herein), so that the connection trace information with a large flow rate is conveniently selected and filled into hardware, thereby avoiding waste of acceleration resources. And the problem of delay caused by the fact that the connection tracking information with small flow is accelerated first and the connection tracking information with large flow can be accelerated only after a long time is solved.
It can be understood that the connection trace information may be arranged according to the flow rate, or may be arranged from small to large, or may be arranged from large to small, or may be arranged after being screened, which may achieve the effect of facilitating the selection of the required connection trace information, and the arrangement order is not limited herein.
And S30, determining the number of required connection tracking information according to the preset acceleration condition of the communication equipment.
Specifically, since the number of required trace connection information is judged, the required number of trace connection information of appropriate traffic can be filled into hardware, thereby maximally utilizing a hardware acceleration function.
S40, selecting the screened connection tracking information according to the number of the connection tracking information, and filling the selected connection tracking information into hardware of the communication equipment.
Specifically, after the required connection trace information is screened (i.e., n connection trace information are screened), if the number of the required connection trace information is large (i.e., x connection trace information is required), if the flow rate is sorted from large to small, the first x connection trace information are selected and filled in the hardware.
In summary, since all the connection trace information is acquired at one time and the connection trace information is screened through the traffic, the waste of acceleration resources is avoided, and the waste of calculation resources during filling is also avoided. And because the number of the required trace connection information is judged, the trace connection information with the required number and proper flow can be filled into hardware, thereby maximally utilizing the hardware acceleration function and not influencing the expansibility of a protocol stack.
As an improvement of the above scheme, the screening the connection trace information according to the flow per second and the forwarding pressure of the connection trace information specifically includes:
a first threshold of traffic per second is determined based on the current communication device.
In this embodiment, the first threshold is set to 2M if the router is a gigabit router, and 500K if the router is a hundred mega router.
And when the forwarding pressure does not exceed a preset pressure threshold value, screening the connection tracking information of which the flow per second is greater than the first threshold value.
In the present embodiment, the preset pressure threshold is set according to the pressure condition of data forwarding, and is not limited herein. When the forwarding pressure does not exceed a preset pressure threshold (that is, the forwarding pressure at this time is considered to be not large), only screening is performed according to the first threshold, that is, the connection tracking information of the gigabit router with the flow rate per second greater than 2M is screened out. And the flow rate of hundreds of megaroads per second is greater than 500K and is screened out.
And when the forwarding pressure exceeds a preset pressure threshold, correspondingly increasing the first threshold to a second threshold, and screening the connection tracking information of which the flow per second is greater than the second threshold.
In this embodiment, when the forwarding pressure exceeds the preset pressure threshold, that is, the data forwarding pressure at this time may be considered to be larger, and at this time, the second threshold may be set to 4M, that is, connection trace information that can be dynamically adjusted to have a flow rate per second larger than 4M is screened out for the gigabit router.
As an improvement of the above solution, the determining the number of the required connection tracking information according to the preset acceleration condition of the communication device includes:
and determining the number of the required connection tracking information according to the computing power of a processor of the communication equipment, the time consumption when the connection tracking information is filled into hardware, the size of hardware acceleration resources and the current acceleration requirement. It should be noted that the number of connection trace information required may also be determined in combination with CPU consumption when filling the connection trace information into the hardware.
It should be noted that if the time consumption level of the padding is small, the number of connection trace information can be increased; otherwise, the number of connection trace information is reduced. If padding takes too much time while a larger number needs to be padded to the hardware, the speed of current data processing and forwarding is affected.
Specifically, the hardware acceleration resource size is the acceleration resource of the collocated hardware accelerator. Current acceleration requirements are related to user actions such as watching video, browsing web pages, playing games, listening to songs, etc. The number of connection trace information can be determined based on a large number of statistics and experience after acquiring the acceleration condition.
Illustratively, if the processor of the router a has multiple cores and a high main frequency, 10000 acceleration resources of the collocated hardware accelerator are provided, and the user frequently uses the speed measurement software to measure the speed for a very short time (such as several seconds). Then, the connection trace information screened each time can be set to 10, the connection trace information with the flow rate larger than 200K is screened, and then 10 connection trace information with the flow rate larger than 200K can be added to the hardware at one time, so as to complete acceleration.
In contrast, the processor of the router B is a single core and has a low dominant frequency, the number of acceleration resources of the collocated hardware accelerator is only 1000, and the user basically only watches video and does not have data needing burst large-flow forwarding. Then, the connection trace information screened each time may be set to 4, and the connection trace information with a flow rate greater than 500K is screened, so that only 4 connection trace information with a flow rate greater than 500K may be added to the hardware at a time to complete acceleration, it should be noted that, because the hardware resources are limited and the configuration is low, a stricter screening condition (that is, the flow rate is greater than 500K) needs to be set.
For example, if a user is playing a large amount of online games at the same time, downloading, listening to songs, refreshing web pages, etc. The connection tracking mechanism will instantly establish N pieces of connection tracking information. If only the n pieces of connection trace information corresponding to the network game have the largest flow, after traversing all the newly-created connection trace information, some pieces of the n pieces of connection trace information (depending on the screening number, if the screening number is greater than n, all) are preferably filled into hardware, and acceleration is completed. The method avoids randomly filling the connection tracking information (such as webpage refreshing) with small flow into the hardware randomly or according to the time sequence established by the connection tracking information, thereby delaying the acceleration of the online game with large flow by the hardware.
As an improvement of the above solution, after the selecting the connection tracing information after the screening according to the number of the connection tracing information, and filling the selected connection tracing information into hardware of a communication device, the method further includes:
and when the hardware needs to perform accelerated forwarding processing next time, judging whether new connection tracking information is read or not.
And in response to that no new connection tracking information is read, selecting connection tracking information from the rest screened connection tracking information according to the number of the connection tracking information and filling the connection tracking information into hardware of the communication equipment.
It should be noted that the new connection trace information is not read, and it can be understood that there is no new traffic demand, which is the same as the previous traffic demand. And if new connection tracking information is read, recalculating the number of the connection tracking information.
Illustratively, if there are ten pieces of connection trace information, the traffic ratios are 10,9 … and 2,1 in turn. Then the connection trace information with a traffic of 10 is most worth populating the hardware. If the number of current settings is limited to 2, then only two connection trace messages of 10 and 9 are populated into the hardware, completing the acceleration. And when the next processing is carried out, if no new connection tracking information is established and the old connection tracking information maintains the original flow, the connection tracking information with the flow of 8 and 7 is filled into hardware when the next processing is carried out, and the acceleration is completed.
