Fig. 2 is the software overview flow chart of the embodiment of the invention.
[embodiment]
Below through concrete embodiment and combine accompanying drawing that the present invention is described in further detail.
Please refer to shown in Figure 1ly, the media gateway log system that this is routine comprises some WMGs and log server; WMG comprises VOIP driver module, journaling agent module and local memory module; In this routine media gateway log system, medium bag snapshot is exported as log event.The VOIP driver module is exported daily record through the journaling agent module; The journaling agent module can be selected the outgoing route of daily record, and preferential selection will be mail to log server as the medium bag snapshot of daily record output; If Communication Block, then journaling agent module selection outgoing route is local memory module; In case WMG and log server communication recovery, the daily record outgoing route can switch to log server again.
Please refer to shown in Figure 2, the media gateway log output intent that this is routine, concrete steps are following:
1) the VOIP driver module is through calling logging application interface (API), issues the journaling agent module after the voice medium package of specified format is dressed up asynchronous message.
2) the daily record flow control of bandwidth on demand: the journaling agent module receives medium bag data output request; Its legitimacy of verification at first; Judged whether the output authority; The journaling agent module is set up differentiation of CPU usage thresholding and daily record switch, comprises the output authority differentiation that the CPU usage thresholding is differentiated and the daily record switch is differentiated.
The process of daily record flow control is following:
The media gateway log proxy module receives log request message, realizes the daily record flow control through control of authority, and authority comprises that the CPU usage thresholding is differentiated and the daily record switch is differentiated.
The CPU usage thresholding is differentiated: database disposes the CPU thresholding respectively to different module in advance, and under the very high situation of telephone traffic, current C PU occupancy surpasses threshold value, for guaranteeing regular traffic function, closing journal output function; When CPU usage falls back to below the thresholding, then open the daily record output function again.
The daily record switch is differentiated: database provides the configuration of module daily record switch; The user can control according to actual needs; Can be very big like medium bag snapshot situation log information flow; Consider that the AM/BAM communication bandwidth has only 100M, journal function that can be through this other module of switch temporary close follow-uply reactivates again.If this daily record switch is in closed condition, then abandon medium bag snapshot daily record output.
3) standby redundancy in log store path: according to the communication conditions between WMG and the log server, the journaling agent module can be selected medium bag outgoing route, and preferential the selection mail to log server with the medium bag.
The standby redundancy strategy in log store path:
Before the media gateway log proxy module sends daily record data, need the communications status between judgement earlier and the log server, if communication is normal, then the daily record outgoing route is chosen as log server; If Communication Block, then the daily record outgoing route is chosen as the WMG local storage medium, like hard disk or reserved memory; Consider that WMG storage resources itself is limited, the time of preservation and capacity are limited, if Communication Block overlong time and log information amount are very big again, when exceeding storage medium permission use maximum, then abandon follow-up data.In case with the log server communication recovery, the daily record outgoing route can switch to log server again.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
