Embodiment
Describe the present invention below with reference to embodiment shown in the drawings.But these execution modes do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these execution modes, method or the function all is included in protection scope of the present invention.
Ginseng Fig. 1 introduces the embodiment that dynamic monitoring message of the present invention is transmitted the congested method of port.In the present embodiment, this method may further comprise the steps:
S1, the inbound port timestamp that obtains message and outbound port timestamp, and calculate described message forwarding time of delay.
Ginseng Fig. 2, wherein, the message forwarding of calculating by port specifically comprises time of delay:
The time of S11, recorded message entry port is the inbound port timestamp;
Time when S12, recorded message arrive message outlet processing module is the outbound port timestamp;
The difference of S13, the described outbound port timestamp of calculating and inbound port timestamp obtains the message forward delay.
Message enters in the bag forwarding chip through port, when each port receives a message, obtain the current time as the inbound port timestamp of this message according to the timestamp engine, message is through message import processing module and packet buffer module subsequently, and enter message outlet processing module, after arriving this module, message has been assigned with a purpose and has transmitted port.In message outlet processing module, obtain the current time as corresponding message outbound port timestamp by the timestamp engine, because message outlet processing module also finally transfers the time-delay relative fixed of chip to port, so difference by outbound port timestamp and inbound port timestamp, obtain can reference the message forward delay, this delay can be used as dynamic monitoring and uses.
S2, will described forward delay time and one group of delay zone between relatively, determining between corresponding delay zone of described forward delay time, and increase the count value in phase delay interval.
At the message forwarding port, can dispose respectively between one group of delay zone.Cooperation is with reference to Fig. 3 and Fig. 4, to comprise 48 ports, and for disposing respectively between 16 delay zones, each port is example, exemplarily, be ltcyThrd0Cnt0 [23:0] between the delay zone of port 0, ltcyThrd1Cnt0 [23:0], ltcyThrd15Cnt0 [23:0], wherein, 0 benchmark postpones to be ltcyThrd0[6:0 between delay zone], this benchmark is postponed displacement one predetermined displacement amount ltcyThrd0Shift[4:0] obtain between delay zone 0 delay upper limit ltcyThrd0[6:0]＜＜ltcyThrd0Shift[4:0], so, determine between delay zone that 0 delay scope is ltcyThrd0[6:0] ~ ltcyThrd0[6:0]＜＜ltcyThrd0Shift[4:0].Similarly, at 1 can reconfiguring new benchmark and postpone between delay zone, and the mode by displacement, obtain the delay scope between corresponding delay zone, certainly, the delay scope between different delay zones can be identical or different, and can carry out the refinement adjustment according to the demand of reality.
Certainly, here only be that demonstration ground hypothesis benchmark length of delay is smaller value, and this benchmark length of delay moved to left obtain a higher value and explain for being limited to example on postponing, in the execution mode of some replacements, can also be that benchmark is postponed to do the processing that moves to right, between the delay zone that obtains being fit to, above-mentioned explanation only is exemplary, and nonrestrictive.
At ltcyThrd0 [23:0], ltcyThrd1 [23:0] between the delay zone of a port ..., ltcyThrd15 [23:0], correspondence disposes counter incr ltcyThrd0Cnt[23:0 respectively], incr ltcyThrd1Cnt[23:0] ..., incr ltcyThrd15Cnt[23:0], if there is message forwarding to postpone to fall into wherein between a delay zone, then Dui Ying counter adds one operation.In actual disposition, between each delay zone at each port, need dispose counter respectively, to reach the purpose of counting respectively.
As preferred embodiment, be continuous each other between between one group of above-mentioned delay zone, that is to say, 0 delay upper limit ltcyThrd0[6:0 between delay zone]＜＜ltcyThrd0Shift[4:0] equal between delay zone 1 benchmark length of delay, also be 1 delay lower limit ltcyThrd1[6:0 between delay zone].Need to prove, in the above-described embodiment, the common factor that does not have length of delay between between two adjacent delay zones, for example, 0 higher limit is ltcyThrd0[6:0 between said delay zone]＜＜ltcyThrd0Shift[4:0] do not represent between delay zone 0 and comprise ltcyThrd0[6:0]＜＜ltcyThrd0Shift[4:0] itself, ltcyThrd0[6:0]＜＜ltcyThrd0Shift[4:0] only for example as 1 lower limit between delay zone, can fall between delay zone 1 scope, and push away class with this.
Complete in a big way section time of delay that contains continuously is conducive to the statistics of science is more made in the delay of port between one group of delay zone setting, avoids lacking necessary statistical sample.
Especially, above-mentioned " increasing the count value in phase delay interval " also comprises and upgrades that shown in Figure 4 to transmit port numbers with message be the concordance list of index.For the necessary information of monitoring is provided, need to safeguard this concordance list here, it is index that this table is transmitted port numbers with message, is example to distribute between 16 delay zones still, this table all needs to read modification for each message and writes once.That is to say, after the count value between a certain delay zone is made amendment, need to upgrade this concordance list.
Cooperation is with reference to Fig. 5, fall into process between concrete delay zone in judgement, at first with endpoint value thrd0, thrd1 between message forward delay ltny and 16 delay zones, thrd2 ..., thrd15 compares judgement, judging between the delay zone that finally falls into, and with 16 counter incr ltcyThrd0Cnt[23:0], incr ltcyThrd1Cnt[23:0] ..., incr ltcyThrd15Cnt[23:0] in the value of corresponding that counter add one.
S3, judge that according to count value current between each delay zone message transmits port and whether be in congestion state.
Particularly, exemplarily provide several below and judge whether message forwarding port is in the mode of congestion state.
Decision procedure 1:
After each message is transmitted, count value current between each delay zone and its corresponding default count threshold are compared;
If the count value between a certain delay zone judges then that greater than its corresponding default count threshold described port is in congestion state.

Decision procedure 2:
After a plurality of messages are forwarded, if the control bit between one or more delay zones of the bigger delay of setting of correspondence is not triggered, then also need carry out following judgement:
After a plurality of messages are transmitted, read count value current between each delay zone;
Judge according to count value current between each delay zone whether message forwarding port is in congestion state.
Between one group of delay zone at configuration, may exist more widely between a plurality of delay zones of corresponding common delay (also can comprise between the delay zone of the bigger delay of correspondence among the embodiment one here), at between this type of delay zone, if wherein the accumulated value of the count value between these a plurality of delay zones surpasses another default count threshold, can judge that then this port is in congestion state.Particularly, the external control chip reads one group of count value between delay zone every predetermined read cycle, and the count value between a plurality of delay zones of wherein corresponding common delay is added up, and compares with corresponding default count threshold, if exceed this default count threshold, then judge congested.
As preferred embodiment, after control chip has read count value between this group of delay zone, with this count value zero clearing.And control chip can read this table at any time to understand the forward delay situation of each target port, here control chip read the back to address contents zero clearing in the counter of reading, can avoid the data volume of long-term accumulated and cause difficult in maintenance.Certainly, in some embodiments, controllably, the address contents zero clearing after can not reading control chip, these all are the replacement technique means that those of ordinary skills can expect easily, must work as to belong in the protection category of the present invention.
Certainly, need to prove, there is not ordinal relation successively in above-mentioned several decision procedures, in the judgement of reality, above-mentioned several decision procedures are complementary forms, that is to say, only need to satisfy wherein a kind ofly to be judged as congested condition, namely can decision making to the congestion state that message is transmitted port, and be not the execution sequence that need follow fixing decision condition.
