Fig. 2 shows the composition of the supervisory control system 200 of content distributing network according to an embodiment of the invention and outside connection diagram.Here content distributing network comprises in the multiple network nodes 320, Fig. 2 be associated with the webserver 310 incidence relation do not illustrated between the webserver 310 and network node 320.Network node 320 realizes the distribution of the service content provided with the webserver 310.The supervisory control system 200 of content distributing network comprises one or more monitor node 210 and monitoring server 220.The supervisory control system 200 of content distributing network realizes the monitoring management to each network node 320.
Fig. 3 shows the deployment schematic diagram of supervisory control system in real network of content distributing network according to an embodiment of the invention.See Fig. 3, in this network design schematic diagram, illustrate user terminal 110, CDN node 120, Web server 130, monitor node 210 and monitoring server 220.User terminal 110 obtains by CDN node 120 service that Web server 130 provides, CDN node 120 is for ensureing the ageing of the service that web server 130 provides, timer access web server 130, to ensure the consistency of the information in CDN node 120 and the information in web server 130, these CDN node 120 constitute a content distributing network.And the supervisory control system of monitor node 210 and monitoring server 220 constitution content distributing network, for realizing the monitoring to each CDN node 120.Here, Web server 130 is the webserver 310 in Fig. 2, and CDN node 120 is the network node 320 in Fig. 2.
Referring to Fig. 2 and Fig. 3, technical scheme of the present invention is described in detail.
See Fig. 2 and Fig. 3, the supervisory control system 200 of content distributing network comprises one or more monitor node 210 and monitoring server 220.Illustrate in fig. 2 in two monitor nodes 210, Fig. 3 and illustrate three monitor nodes 210, but this all can not as the restriction of the monitor node number in the supervisory control system to content distributing network of the present invention.
See Fig. 2, monitoring server 220 comprises journal processing unit 221, effectively node determining unit 222, monitor node linkage unit 223 and abnormal nodes determining unit 224.
Access log before the appointment moment that journal processing unit 221 obtains the webserver 310, therefrom obtains network node and returns Source log, use when determining effective network node list for effective node determining unit 222.
Specifically, journal processing unit 221 is suitable for each access log traveled through before the appointment moment of the webserver 310 obtained, judge whether this access log returns Source log as network node by the access links in this access log, retain, otherwise delete, thus acquisition network node returns Source log.
Such as; in the network design shown in Fig. 3, it is as follows that CDN node returns Source log example: 119.146.194.11121.8.137.56--[18/Sep/2012:23:59:59+0800] " GET/secache.html 39130838.html HTTP/1.1 " 20085861 "-" " Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NETCLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; MAAR; .NET4.0C; .NET CLR 1.1.4322; .NET4.0E; Media Center PC 6.0; 360SE) " "-" hao.360.cn 75686138167984
Wherein " GET/secache.html 39130838.html HTTP/1.1 " represents the http request secache.html(page of access node, this page does not exist in fact, web server receives this request will return home tip), namely CDN node returns the http request that source request will send to web server as upper pathway.Because request is with timestamp parameter, and CDN node is not preserved corresponding page info, therefore request penetrates CDN node and directly accesses web server.
The log example of normal users request is as follows: 61.164.60.244175.180.112.40,203.66.41.51--[19/Sep/2012:00:00:00+0800] " GET/xinwenmeiti.html HTTP/1.1 " 20015886 " http://hao.360.cn/ " " Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0; MAAU) " "-" hao.360.cn 702161377374
Above-mentioned daily record represents the normal http request xinwenmeiti.html page of http request, belongs to normal user request, not CDN node request.
Therefore, in the network design shown in Fig. 3, distinguish CDN node according to the access links in daily record and return Source log and other daily record.If the access links in daily record starts with secache.html, then this daily record is that CDN node returns Source log.As returned in the example of Source log in above-mentioned CDN node, access links is " GET/secache.html 39130838.html HTTP/1.1 ", and it starts with secache.html, therefore can confirm that this daily record is that CDN node returns Source log.And in the log example of above-mentioned normal users request, access links is " GET/xinwenmeiti.html HTTP/1.1 ", not with secache.html beginning, therefore not that CDN node returns Source log.Above to being whether that the judgement that CDN node returns Source log is only way of example, so the CDN node can distinguished in web server log returns the mode of Source log and general access log all within protection scope of the present invention.
In addition, first IP address in daily record is the IP address of visitor.Therefore confirming after CDN node returns Source log, CDN node is determined in first the IP address can returned in Source log according to CDN node.As returned in the example of Source log in above-mentioned CDN node, 119.146.194.11 is the IP address of CDN node.
The network node that effective node determining unit 222 is suitable for obtaining according to journal processing unit 221 returns Source log and determines effective network node list, and what comprise in active block node listing is the IP address of active block node.Specifically, effective node determining unit 222 is suitable for returning to network node each network node occurred in Source log, according to network node return Source log judge this network node return source number of times whether be less than preset value and last Hui Yuan whether before second specifies the moment, if it is judge that this network node is invalid, otherwise this network node is put into effective network node list, specifically effective network node list is put in the IP address of this network node.Wherein, second the moment is specified to be specify a time point before the moment.
Such as, in one embodiment of the invention, specify the moment to be the zero point of today, then second specify the moment be zero point today before sometime, such as, before can being zero point today moment of 1 hour, i.e. 23 points of yesterday.If the time of a last Hui Yuan of network node before 23 of yesterday, then illustrate this network node 23 of yesterday to zero point today during this period of time in there is no Hui Yuan, this network node may fail when zero point today.Therefore, by returning source number of times and whether be less than preset value and whether last Hui Yuan specifying judgment rule before the moment second, failed network node when effective node determining unit 222 can eliminate zero point today, thus unspent each network node when remaining into zero point today, these are the objects will monitored today to each network node unspent during zero point today.
Monitor node linkage unit 223 and the communication of each monitor node 210, issue the active block node listing that will monitor to each monitor node 210, and receive the monitoring access log that each monitor node reports.Specifically, active block node listing is sent to one or more monitor node 210 by monitor node linkage unit 223, and receive the monitoring access log that one or more monitor node 210 returns, generate monitoring access log is accessed each network node in active block node listing during by monitor node 210.
Each monitor node 210 is suitable for accessing each network node in active block node listing, and record monitoring access log, recorded monitoring daily record is returned to the monitor node linkage unit 223 in monitoring server 220.In Fig. 2, multiple monitor node 210 is distributed in different network sites.Specifically, each monitor node 210, after receiving the active block node listing issued, carries out the access of respective service to the all-network node in this active block node listing, and record monitoring daily record.Have recorded the abnormal conditions of access in monitoring daily record.
Abnormal nodes determining unit 224 is suitable for, according to monitoring access log, determining abnormal network node listing.Specifically, the monitoring access log that abnormal nodes determining unit 224 is suitable for recording at one or more monitor node shows, for a network node, at least one monitor node accesses this network node abnormality, and the number of times of access exception is when reaching pre-determined number, determine that this network node is abnormal network node, this node is put into abnormal network node listing.
In one embodiment of the invention, for a network node, abnormal nodes determining unit 224 can just determine that when a monitor node accesses this network node abnormality this network node is abnormal network node.Or consider that the position of different monitor nodes residing for it is different, some monitor node may be that the network environment residing for himself is poor and cause accessing the problem of this network node abnormality, in another embodiment of the present invention, abnormal nodes determining unit 224 can access this network node abnormality at multiple monitor node or even whole monitor node, and the number of times of access exception is when reaching pre-determined number, determine that this network node is abnormal network node.
Alternatively, abnormal nodes determining unit 224 can also determine abnormal network node further in conjunction with journal processing unit 221.First, journal processing unit 221 can also be suitable for the access log after the appointment moment of the acquisition webserver.Subsequently, abnormal nodes determining unit 224 is after as mentioned above according to monitoring access log determination abnormal network node listing, the each abnormal network node in abnormal network node listing can also be traveled through, from journal processing unit 221 obtain the webserver the appointment moment after access log search whether exist this abnormal network node return Source log, if there is no, then this abnormal network node is deleted from abnormal network node listing.Here, if what there is this abnormal network node in the access log after the appointment moment returns Source log, then show this abnormal network node still in a network not by undercarriage, illustrate that CDN does not also find this abnormal network node, therefore need the keeper to CDN to notify this abnormal network nodal information.Otherwise show this abnormal network node in CDN by normal undercarriage, so there is no necessaryly this network node to be placed in abnormal network node listing and to inform the keeper of CDN.
Thus, abnormal nodes determining unit 224 can be deleted further from abnormal network node listing, specifying after the moment to be found its network node that is abnormal and normal undercarriage.
Above-mentioned supervisory control system can be monitored the abnormal network node of content distributing network effectively, solve the monitoring problem of the abnormal network node in content distributing network thus, achieve the beneficial effect effectively content distributing network being carried out to maintenance and management.
Fig. 4 shows a kind of according to an embodiment of the invention flow chart of method for supervising of content distributing network.This content distributing network comprises the multiple network nodes be associated with the webserver.
The method for supervising of this content distributing network starts from step S410 as shown in Figure 4, the access log before the appointment moment obtaining the webserver in this step, therefrom obtains network node and returns Source log.
This step is time Source log filtering out network node from the daily record of the webserver.In one embodiment of the invention, obtain the access log before the appointment moment of the webserver, therefrom obtain network node to return Source log and comprise: travel through each access log before the appointment moment of the webserver obtained, judge whether this access log returns Source log as network node by the access links in this access log, retain, otherwise delete, thus acquisition network node returns Source log.
This step S410 can perform in the monitoring server 220 of the system above shown in Fig. 1, is specifically performed by journal processing unit 221 in monitoring server 220.
Subsequently in the step s 420, return Source log according to network node and determine effective network node list.
In one embodiment of the invention, return Source log according to network node and determine that effective network node list comprises: network node is returned to each network node occurred in Source log, according to network node return Source log add up this network node return source number of times whether be less than preset value and last Hui Yuan whether before second specifies the moment, be judge that this network node is invalid, otherwise network node put into effective network node list.Wherein, second the moment is specified to be specify a time point before the moment.
Such as, in one embodiment of the invention, specify the moment be the zero point of today, then second specify the moment be zero point today before sometime.Effective node determining unit 222 is unspent each network node before can determining zero point today, and these unspent each network nodes before zero point today are the objects will monitored today.Failed network node today is eliminated in the effect of this step S420 as far as possible.
This step S420 can perform in the monitoring server 220 of the system above shown in Fig. 1, is specifically performed by the effective node determining unit 222 in monitoring server 220.
In step S430, active block node listing is sent to one or more monitor node, make each network node in one or more monitor node access active block node listing, and access log monitored in record separately.
In one embodiment of the invention, each monitor node, after receiving the active block node listing issued, carries out the access of respective service to the all-network node in this active block node listing, and record monitoring daily record.Have recorded the abnormal conditions of access in monitoring daily record.The plurality of monitor node is the multiple monitor nodes being distributed in heterogeneous networks position.
