As a preferred embodiment, above-mentioned speed limit rule can be real by the speed limit rule chain in POSTROUTING chains
It is existing, specifically it can increase node in speed limit rule chain head, for judging whether the destination address of downlink message belongs to affiliated gateway
Local address in the present embodiment can be defeated by the output interface of downlink message from the flow controller of affiliated gateway local address
Go out, without carrying out flow restriction, realizes when carrying out message rate-limiting to client by flow controller on gateway, client
The purpose of the gateway configuration management page can normally be accessed.
In a preferred embodiment, further include after executing the step S1：Judge whether downlink message is that affiliated gateway is local
The downlink message of address, if so, executing step S2；If it is not, according to speed limit rule to the downlink report except affiliated gateway local address
After text carries out class indication, step S3 is executed.
In the present embodiment, pass through the form to beating class indication (mark) except the downlink message of affiliated gateway local address
It distinguishes, the downlink message with class indication can be carried out by flow restriction according to the mark of class indication in exit.
As shown in Fig. 2, in a preferred embodiment, the detailed process of step S5 is：
S51. corresponding downlink message is made an addition in preset classification queue according to class indication；
S52. it is put in order according to the downlink message of preset classification queue and exports downlink message from output interface, knot
Beam.
In the present embodiment, flow control can be realized by establishing a classification queue at output port.Downlink report
Text carries out judgement selection after input interface is come in, by input demultplexer：The downlink message for being equipped with class indication is sent to
Forwarding module processing, by check routing table obtain downlink message next destination, to downlink message be arranged such that by
It is delivered to output interface.
In a preferred embodiment, according to speed limit rule to classifying except the downlink message of affiliated gateway local address
Further include before mark：
The downlink message for not meeting speed limit rule is abandoned.
In the present embodiment, it can be realized by the flow controller that linux kernel provides, when downlink message connects from input
After mouth is come in, downlink message against regulation is abandoned to realize the purpose of flow restriction by flow restriction.
As shown in figure 3, a kind of flow controller, to carry out flow restriction to the downlink message of transmission, including：
One receiving unit 1, to receive the downlink message of transmission；
One processing unit 2 connects receiving unit 1, provides speed limit rule, processing unit 2 is to according to speed limit rule general
The downlink message of affiliated gateway local address exports；
One recognition unit 3, connection processing unit 2, to identify whether downlink message has class indication；
One current limiting unit 4 connects recognition unit 3, and the downlink message will carry class indication carries out flow restriction；
One output unit 5, is separately connected recognition unit 3 and current limiting unit 4, to export downlink message.
It in the present embodiment, can be directly by the downlink message of the affiliated gateway local address of not class indication from flow control
The output interface of device processed exports, and without carrying out flow restriction, solves after carrying out message rate-limiting to client on gateway, client
End accesses the problem of gateway configuration management page leads to system failure.
As shown in figure 4, in a preferred embodiment, further including：
One judging unit 6, connect with receiving unit 1 and processing unit 2 respectively, to judge whether downlink message is affiliated
The downlink message of gateway local address；
Processing unit 2 exports the downlink message of affiliated gateway local address according to speed limit rule, and is advised according to speed limit
Class indication then is carried out to the downlink message except affiliated gateway local address.
In the present embodiment, by judging unit 6 to beating class indication except the downlink message of affiliated gateway local address
(mark) form distinguishes, and through the processing unit 2 can will have contingency table in exit according to the mark of class indication
The downlink message of knowledge carries out flow restriction.
In a preferred embodiment, current limiting unit 4 includes：
One Queue module 42 provides preset classification queue, under Queue module 42 according to class indication to incite somebody to action accordingly
Row message makes an addition in preset classification queue；
Output unit 5 according to the downlink message of preset classification queue putting in order downlink message from output interface
Output.
In the present embodiment, a classification queue can be established by Queue module 42 to realize flow control.Downlink message
After input unit is come in, judgement selection is carried out by recognition unit 3：The downlink message for being equipped with class indication is sent to forwarding module
Processing, by check routing table obtain downlink message next-hop, using current limiting unit 4 to downlink message be arranged such that by
It is delivered to the output of output unit 5.
In a preferred embodiment, processing unit 2 includes：
One rejects module 21, to reject the downlink message for not meeting speed limit rule.
By the way that the limit efficiency that flow restriction can be improved will be rejected with the unmatched downlink message of speed limit rule.
In the present embodiment, it can be realized by the flow controller that linux kernel provides, when downlink message is single from input
After member is come in, the purpose of flow restriction is realized to abandon downlink message against regulation by rejecting module 21.
In technical solution, when client, which accesses gateway management, configures the page, HTTPD processes can be triggered and handled.
When gateway uses downlink speed limit, first IP information filtering can be inserted into output data packet (POSTROUTING) chain
(iptables) regular：Data message to coming from gateway local directly returns to (return) processing, that is, comes from gateway
Local data message will not stamp class indication by follow-up rule, would not be entered in any current limliting queue in exit,
The phenomenon that avoid HTTPD processes from occupying excessive system resource because of long transmission data, lead to system failure.
The foregoing is merely preferred embodiments of the present invention, are not intended to limit embodiments of the present invention and protection model
It encloses, to those skilled in the art, should can appreciate that all with made by description of the invention and diagramatic content
Equivalent replacement and obviously change obtained scheme, should all be included within the scope of the present invention.
