Abstract
The invention relates to the field of communication, and discloses a method for controlling the sending rate of a RADIUS (Remote Authentication Dial In User Service) messages. The method comprises the following steps of A, setting the maximum number Xmax of messages sent per second on equipment, and developing a section of cache for storing RADIUS messages to be sent in a system; B, setting a time interval of a scanning timer of a queue, and setting time for scanning the cached queue at the timer, wherein the time interval is shorter than 100 milliseconds, and a time length of the timer is shorter than 1 second; C, acquiring current system time of which the unit is second, rounding and obtaining the initial time Tinit of the current system time, and recording the number of messages which are sent till the current system time as Xsendold 0; D, when new RADIUS messages are generated by the equipment, storing the new RADIUS messages to the tail of the cache for sending; E, acquiring system time Tnow, acquiring the maximum number Xsend of messages which are sent this time according to Xsend=Xmax*(Tnow-Tinit)-Xsendold, sending not more than Xsend messages, adding the number Xsendold of the messages which are sent till the current system time to Xsend, and storing the sum as the value of Xsendold. According to the method, the messages can be uniformly sent, and impact on a RADIUS server is avoided.
Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of method of control RADIUS message transmitting spped rate.
Background technology
RADIUS is a kind of AAA(Authentication, Authorization, Accounting) the network application agreement of type, for functions such as authentication, authorization, accountings.This protocol realization is for the Long-distance Control of user's access.Usually, a radius server can receive the RADIUS message of multiple network equipment, like this, very high requirement is proposed to the disposal ability of radius server: if a radius server is connected with 10 network equipments, the maximum transmissions per second of every platform 2000 messages, then radius server needs are per second can process 20000 messages, for most server, it is inconvenient for reaching such processing speed, overstocking and postponing, the serious collapse that even may cause radius server of message will be caused.Therefore, the server requirement network equipment carries out speed limit to transmission RADIUS message.Therefore the network equipment does the restriction of a maximum transmission hundreds of message per second usually.But, generation due to RADIUS message has paroxysmal feature---and such as line card the reason such as to be restarted and user's short time may be caused to roll off the production line in a large number and reach the standard grade, in one second, same transmission rate is uneven like this: a possible hundreds of message all mails to radius server in several milliseconds, server is impacted, affects treatment effect.
Summary of the invention
The present invention is directed to the network equipment in prior art and there is paroxysmal shortcoming to radius server transmission message, provide a kind of method of control RADIUS message transmitting spped rate.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A method for control RADIUS message transmitting spped rate, comprises the following steps:
A: maximum transmission message number Xmax per second is set on equipment, and open up one section of buffer memory in systems in which and the radius message to be sent such as to deposit;
B: the scanning Timer interval that queue is set, the time interval is less than 100 milliseconds; At timer setting timing scan buffer queue, this timer duration is less than 1 second;
C: obtain present system time, chronomere is second, then round and obtain the initial time Tinit of present system time, and recording present system time, to have sent message number be Xsendold 0;
D: after equipment produces new RADIUS message, is stored in buffer memory afterbody etc. to be sent;
E: get system time Tnow, obtains this and sends maximum message segment number Xsend=Xmax*(Tnow-Tinit)-Xsendold, send the message being no more than maximum message segment number Xsend; Add that present system time has sent message number Xsendold and saved as Xsendold value;
F: after arriving timer duration, performs step e);
G: repeat step D) and F).
As preferably, described equipment and radius server run in an ip network respectively, and described equipment and radius server carry out cooperating.
As preferably, described equipment is router or access server.This equipment is the arbitrary network equipment that can carry out the transmission of radius message, comprises router, access server etc.
The present invention, owing to have employed above technical scheme, has significant technique effect:
The present invention arranges maximum transmission message number Xmax per second, record and sent message number Xsendold current second, the network equipment is (interval is less than 1 second) acquisition present system time Tinit at set intervals, unit second, be accurate to millisecond, triggered by event (as receive RADIUS message, the timer time of setting arrive) and send RADIUS message, calculate the difference of current time Tnow and Tinit, current maximum transmission message number Xsend=Xmax*(Tnow-Tinit)-Xsendold.Like this, just achieve the even transmission of message, avoid the impact to radius server.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
