Description
Technical field
The present invention relates to the communications field, in particular to a kind of method of adjustment of ageing time and system, modulator-demodulator.
Background technology
Modem (modulator-demodulator) mainly comprises dual mode to the processing of multicast at present: Internet igmpinternet (Internet Group Management Protocol, abbreviate IGMP as) proxy and IGMP snooping technology, wherein IGMP Snooping (igmp snooping) is relatively simple, operate mainly in link layer, it is by the IGMP message between monitoring client and the router side, thereby at the multicast table entry of setting up at certain multicast.The mapping relations that comprised multicast address, physical port and VLAN (Virtual Local Area Network abbreviates VLAN as).Can set up multicast table on the two-layer switching equipment of not supporting IGMP by use IGMP Snooping, thereby reach the saving bandwidth, the purpose of control multicast message routing direction mainly makes under the modem bridge mode and realizes multicast mechanism in this way:
Step S1 when receiving IGMP general polling message from the upper united mouth, directly transmits message at all lan mouths.
Step S2, when receiving the IGMP report message of lan mouth, at first search medium access control (the Media Access the Control whether user's (by MAC Address sign) who sends this message has added this message ip multicast group correspondence at multicast MAC table, abbreviate MAC as) multicast group, if found corresponding clauses and subclauses according to MAC multicast address, the port numbers that receives the report message and source MAC then illustrated that this user has added the multicast group of report message appointment, upgrade its ageing time, message is transmitted in the upper united mouth.If do not find corresponding clauses and subclauses to illustrate that this port does not also add the multicast group of appointment in the report message, so will be according to multicast mac address, physical port, the newly-built clauses and subclauses of source MAC, and ageing time is set, the report message is transmitted at the wan mouth.
Step S3, when receiving the IGMP leave message of lan mouth, equally with (multicast address, the lan port, source MAC) searches multicast MAC table and whether had this forwarding entry, there are then these clauses and subclauses of deletion from multicast MAC table, and only search the clauses and subclauses of whether also depositing other with multicast address, if exist explanation to also have other lan mouth to need this multicast, then IGMP leave bag is lost no longer and transmitted to the wan mouth, if there is no other clauses and subclauses of this multicast are then transmitted IGMP leave message to the wan mouth.
From top flow process as can be seen, modem itself can initiatively not send query message (query message) to the lan mouth under IGMP snooping pattern, it is the query message that passive forwarding first line of a couplet equipment sends, the ageing time of each clauses and subclauses all is could upgrade after receiving the report message in the multicast MAC table, and the report message is that the user initiatively initiates when for the first time adding multicast group, the report message of back all is to send when responding the query message, and we can know that the ageing time of MAC forwarding entry depends on modem first line of a couplet equipment transmission query message like this.
In actual applications, the inventor finds, the time interval of supposing first line of a couplet equipment transmission query is 180 seconds, and the aging initial time of multicast forwarding clauses and subclauses is 120 seconds among the modem, after sending the query message, first line of a couplet equipment have certain user to add multicast 239.1.1.1 within 60 seconds from port eth1, will cause the first line of a couplet equipment query message next time that also do not have enough time to send like this, ageing time is just overtime, cause corresponding MAC forwarding entry deleted, modem can not transmit the multicast data flow of 239.1.1.1 again to eth1.Simultaneously, the initial value of ageing time sends the blanking time of query bag less than first line of a couplet equipment in multicast MAC table, might cause the interruption of the lan port multicast data flow of modem because of the overtime of ageing time, so first line of a couplet equipment must be sent the ageing time of being arranged to the blanking time of query greater than IGMPsnooping, the ageing time of the IGMP snooping function of present most of modem is all fixed, there is not configuration interface on the user interface, after dispatching from the factory, modem can not change, top fault so just might appear and the blanking time of needs adjustment first line of a couplet equipment transmission query, have only the modem of minority can revise the ageing time of IGMP snooping, but also need the staff ageing time to be set according to the query time interval of first line of a couplet equipment, more loaded down with trivial details.

Embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 1 is the schematic diagram according to the Adjustment System of the ageing time of the embodiment of the invention.
As shown in the figure, the Adjustment System of this ageing time comprises first line of a couplet equipment 10 and modulator-demodulator 20.
Wherein, first line of a couplet equipment 10 is used to send query message, and this first line of a couplet equipment 10 can be multicast router, various wired access devices such as bas; And modulator-demodulator 20 be used to receive described query message, monitor two continuous described query messages the time interval and with the described time interval as ageing time.
Whether first line of a couplet equipment can also be used for detecting has the user to add multicast group, and detecting under the situation that the user adds multicast group, sends described query message.
From the Adjustment System of this ageing time as can be seen the present invention can send the IGMP snooping ageing time of revising modem blanking time automatically of query message according to first line of a couplet equipment.
Fig. 2 is the flow chart according to the method for adjustment of the ageing time of the embodiment of the invention.As shown in Figure 2, this method may further comprise the steps:
Step S102, modulator-demodulator receives the query message from first line of a couplet equipment.
Before this step, whether described first line of a couplet equipment can detect earlier has the user to add multicast group; And described first line of a couplet equipment sends described query message detecting under the situation that the user adds multicast group.
Step S104, described modulator-demodulator is monitored the time interval of two continuous query messages.
For example, described modulator-demodulator monitor time interval of two continuous query messages can be in the following ways: described modulator-demodulator is created first variable and second variable; Described modulator-demodulator utilizes described first variable and described second variable to preserve the time of described two continuous query messages respectively; And described first line of a couplet equipment detecting under the situation that the user adds multicast group, and the time difference that described modulator-demodulator is preserved described second variable and described first variable adds the initial value of the very first time as described ageing time.
Particularly, during modem system start-up, create several variablees, query_first (being used to preserve the time that a preceding query message arrives), query_second (being used to preserve the time that a back query message arrives), timer query_timer, ageing time initial value query_timeout.
Preferably, do not having the user to add under the situation of multicast group, initial value that can ageing time is set to zero, thereby multicast can not be worn out when initial.
When initial, owing to add any multicast group without any the user, first line of a couplet equipment just can not send the query message, therefore can't know the blanking time that the query message sends, also do not send the query message for fear of first line of a couplet equipment, user's multicast forwarding clauses and subclauses occur with regard to aging problem, and composing initial value to query_timeout is 0.
Wherein, suppose that these two continuous described query messages are first query message and second query message, said method can also comprise: described modulator-demodulator judges whether to receive described second query message in second time after receiving described first query message; And described modulator-demodulator do not receive under the situation of described second query message in described second time, upgrades the ageing time of all clauses and subclauses with described initial value.
Step S106, described modulator-demodulator with the described time interval as ageing time.This ageing time is the ageing time of all clauses and subclauses in the multicast table.
Preferably, said method can also comprise: whether described modulator-demodulator detects and changes described blanking time; And described modulator-demodulator is under situation about changing described blanking time, according to described blanking time described ageing time being adjusted.
In the embodiment of the invention, after Modem started, when Any user added multicast group, first line of a couplet equipment began to send the query message, can know the time interval of query message transmission by monitoring two continuous query messages,
With the ageing time of above-mentioned time interval preservation as IGMP snooping, as long as have the user to add multicast group later, just can be with the value of this preservation initial value as ageing time, if finding the blanking time of first line of a couplet equipment transmission query message in addition changes, then the value of preserving among the modem is also made corresponding change, has guaranteed that like this IGMPsnooping ageing time changes with the change that first line of a couplet equipment sends query message blanking time.
Fig. 3 is the flow chart that obtains ageing time according to the embodiment of the invention.
Step S302, when initial, ageing time initial value query_timeout=0.
Step S304, when receiving a query message, first variable is preserved this query message, that is, and the time of advent of this query message of query_first=.
Step S306, when receiving next query message, second variable is preserved this query message, that is, and the time of advent of this query message of query_second=.
Step S308, ageing time is that the difference of second variable and first variable adds a time value.That is query_timeout=query_second-query_first+10.
From this embodiment as can be seen, first line of a couplet equipment begins to send the query message to the wan of modem mouth after having the user to add multicast group.Modem will receive that the time of first query message is saved in query_frist, the time of receiving next query message is saved in query_second, and the value that query_second deducts query_first is added time t1 (span can between 10～180 seconds) compose and give query_timeout, adding time t1 is in order to guarantee that the ageing time initial value is greater than the blanking time that sends the query message, again the time that two the query messages in back is arrived is kept among query_first and the query_second then, according to this supervision query message that do not stop of circulation blanking time of issuing, the query_timeout value upgrades in time.
Step 4, for the first time obtain query_timeout value after, will be with the ageing time of these all multicast entrys of value renewal.
Fig. 4 is the schematic diagram that IGMP snooping ageing time is set according to the embodiment of the invention.
As shown in Figure 4, when the user adds any multicast group, judge at first whether query_timeout is 0,, be equivalent to guarantee that these multicast forwarding clauses and subclauses can be by aging before blanking time not getting access to query to ageing time if be 0 then be more than half an hour; If be not 0 then query_timeout is set to ageing time.
Preferably, after receiving the query message each time, restart timer query_timer, timing is that query_timeout adds time t2 (scope can between 1＜t2＜10 second), if timer expiry is also confiscated the query message, then upgrade the ageing time of all clauses and subclauses, to guarantee that first line of a couplet equipment issues the modification of query blanking time and can not influence normal multicast service with query_timeout.
As can be seen from the above description, the present invention can adjust the ageing time of adjusting demodulator simply, easily.
Need to prove, can in computer system, carry out in the step shown in the flow chart of accompanying drawing such as a set of computer-executable instructions, and, though there is shown logical order in flow process, but in some cases, can carry out step shown or that describe with the order that is different from herein.
Fig. 5 is the schematic diagram according to the modulator-demodulator of the embodiment of the invention.As shown in the figure, this modulator-demodulator comprises receiver module 502, monitors the module 504 and first adjusting module 506.
